Description

BACKGROUND OF THE INVENTION

The present invention relates to a table extension for an agricultural bagging machine, and in particular to a table extension that moves between a bagging position and a transport position preferably under hydraulic power.

Agricultural bagging machines are well known in the art, and are used to bag all types of agricultural materials into very long plastic bags. The bags are essentially horizontal silos that lie on the ground. The bagging machines consist of some type of a loading device like a conveyer or hopper, which feeds the material to an auger or rotor that forces the material into the bags. Often the machines include some means to control the density or compaction of the material in the bag. As the bags fill, the agricultural bagging machine moves forward in a controlled manner and deploys the bag horizontally along the ground.

During operation, trucks unload the material to be bagged into the loader of the agricultural bagging machine at a rate controlled by the throughput of the bagging machine. In most situations the trucks can unload faster than the agricultural bagging machine can process the material, as such the trucks tend to back up and wait to unload the material.

Additionally, the agricultural bagging machines can be quite large. The bags alone can reach 12 to 14 feet in diameter, with the machine at least this wide. Obviously, the machines are of such a size that transportation of the machines can be difficult. Agricultural bagging machines are often too wide to transport safely, or legally, within a single lane of traffic.

Thus, a need exists for a device that can increase the capacity of agricultural bagging machines and that can be safely transported on conventional roadways.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a table extension for an agricultural bagging machine that moves between a bagging position and a transport position.

These and other objects of the present invention will become apparent to those skilled in the art upon reference to the following specification, drawings, and claims.

The present invention intends to overcome the difficulties encountered heretofore. To that end, a table extension is provided and is adapted for movement between a bagging position and a transport position for use with an agricultural bagging machine. The table extension comprises a table for conveying material to be bagged to the agricultural bagging machine, a frame for supporting the table, and a lift mechanism adapted for moving the table between the bagging position and the transport position with the lift mechanism in operable communication with said frame.

DETAILED DESCRIPTION OF THE INVENTION

In the Figures, FIG. 1 shows a table extension 10 of a type that includes a conveyor 11 for conveying material to be bagged to an agricultural bagging machine 12 (see FIGS. 2-3). In the preferred embodiment of the invention, the agricultural bagging machine 12 is a Roto-Pac bagging machine provided by Sioux Automation Center of Sioux Center, Iowa. Those of ordinary skill in the art will understand that the present invention is not necessarily so limited.

The table extension 10 is preferably designed for use as a secondary or additional means of conveying material to be bagged, in that it attaches to a conveyor that is permanently attached at an intake end of the agricultural bagging machine 12. Again, the invention, however, is not necessarily limited thereby. The use of the table extension 10 adds capacity to the agricultural bagging machine 12, helps to level out the material to be bagged across the width of the conveyor 11 so as to increase the throughput of the agricultural bagging machine 12, and due to the unique design of a lift mechanism 14 of the table extension 10, allows the table extension 10 to easily move between a bagging position and a transport position (see FIGS. 1, 2). Furthermore, the unique design of the table extension 10 is of a width that allows it to be transported on conventional roadways while in the transport position.

For ease of reference, the table extension 10 is given two distinct frames of reference depending on whether the table extension 10 is in the transport or bagging positions. In particular, in the transport position the table extension 10 is capable of being towed by a vehicle (not shown). Accordingly, in this position the table extension 10 has a forward end 20 located at the end closest to a trailer hitch 18 and a rearward end 22 opposite thereto (see FIG. 1). In the bagging position, the table extension is attached to the conveyer of the agricultural bagging machine 12. As mentioned, the table extension 10 transports the material to be bagged to the machine 12. Thus, in this position the conveyor has a forward end 24 were the material to be bagged is loaded from a truck 16, and a rearward 26 opposite thereto were the material to be bagged exits the table extension 10 and enters the conveyor of the agricultural bagging machine 12 (See FIG. 2).

It should be noted that the direction of movement of the table extension 10 when in the transport position is perpendicular to the direction of movement is different of the table extension 10 when in the bagging position. The relative directions of movement correspond to the orientation of the forward and rearward ends in the two positions. That is, in the bagging position the agricultural bagging machine 12 moves in a direction that moves the forward end 24 of the table extension 10 ahead of the rearward end 26. Likewise, in the transport position the table extension 10 is moved under the power of a towing vehicle that moves the forward end 20 of the table extension 10 ahead of the rearward end 22.

In operation, the table extension 10 includes a table 30 that utilizes conventional chain and slat means to convey the material from the forward end 24 to the rearward end 26 during bagging operation. The table extension 10 includes a conventional hydraulic table motor 28 mounted to the table 30 for this purpose (the motor 28 is shown in detail but not described as it is of a conventional design and not considered an essential component of the present invention). The table 30 further includes hook plates 33 (see FIGS. 13, 15) that fit over a nose tube 27 (see FIG. 17) of the load table of the agricultural bagging machine 12 in the bagging position. In particular, FIG. 13 shows the hook 33 portion of the table 30 located on the forward end 20 of the table extension 10, while FIG. 15 shows the hook 33 portion of the table 30 located on the rearward end 22 of the table extension 10. The hooks 33 mount to plates 25 attached to the side of the table 30. The hooks 33 are shaped to fit over an end of a conveyor axle 124, which is driven by the motor 28 used to drive the conveyor 11. The hooks 33 also contain a slot 126 shaped to fit over table brackets 31. Conventional nut and bolt fasteners 39 secure the hooks 33 to the table 30. In particular, a rectangular bracket 35 secures to the table bracket 31 on one end of the hooks 33. On the rearward end 22 (FIG. 15), the hook 33 also includes an angle bracket 37 pivotally attached to an ear 128 on the upper edge of the table 30, and then the fasteners 39 secure the hook 33 to the bracket 37. On the forward end 20 (FIG. 13), the hook 33 attaches directly to the ear 128 and uses a rectangular bracket 35. Finally, a ring 34 is provided to fit around the end of the nose tube 27. A fastener 29 is then attached to a pin 43 located on the hook 33 to hold the ring 34 in place.

The table extension 10 includes a lift mechanism 14 that underlies and supports the table 30. The table extension 10 also includes moveable side panels 23 that move into an upright horizontal position when the table extension 10 is in the bagging position, and lie flat on top of the table 30 when table extension 10 is in the transport position (see FIGS. 1-2).

The lift mechanism 14 moves the table extension 10 between the bagging and transport position, as well as providing support for the table 30. The lift mechanism 14 utilizes a plurality of hydraulic cylinders to operate a modified 4-bar linkage 34 to accomplish the movement. In particular, an axle lift cylinder 36 and a main folding cylinder 38 are the primary cylinders for moving the lift mechanism 14 between the bagging position and the transport position. The lift mechanism 14 also utilizes a table angle cylinder 40 and a hitch height cylinder 42 in the process. Accordingly, in the preferred embodiment of the invention the lift mechanism 14 is hydraulically driven and includes a power 4-bank hydraulic valve and manifold 44 (see FIG. 18) for control and supply of hydraulic power to the cylinders 36, 38,40, 42.

The structural components of the lift mechanism 14 will now be described in order better understand the movement of the lift mechanism 14 between the bagging and transport positions. These components comprise generally an axle assembly 46, a linkage assembly 56, and a hitch assembly 64, and will be described initially while in, and in reference to, the transport position. The axle assembly 46, best shown in FIGS. 6, 7, of the lift mechanism 14 includes and axle 48 that connects to two wheels 50 used for transportation of the table extension 10. An axle frame 52 is connected to the ends of the axle 48 with conventional nut and bolt fasteners 49, and is generally located above and forward of the axle 48. The axle frame 52 includes two side beams 54 connected perpendicularly to an axle cover 51 of the axle frame member 52. The axle cover 51 secures directly over the axle 48, with the side beams 54 extending forward therefrom. The axle frame 52 also includes struts 58 secured to the side beams 54 and the axle cover 51 for additional support. Also, the axle frame 52 includes a cylindrical pivot bar 53 that secures to collars 63 on the forward end of either side beam 54. A linkage saddle 55 attaches to the center of the axle cover 51. A pivot lever 66 secures to the pivot bar 53 by attaching a nut and bolt fasteners 47 through a pivot lever bracket 65 that surrounds a portion of the pivot bar 53 and attaches to a rounded bracket end 17 of the pivot lever 66. The axle lift cylinder 36 secures on one end to a lower ear 67 on the pivot lever 66, and the other end secures at the junction of the side beam 54 and the axle 48. The pivot lever 66 also includes an upper ear 69.

Turning now to the linkage assembly 56, shown best in FIGS. 6, 9, and 8, the linkage assembly 56 is comprised of two longitudinally orientated frame members 62. A plurality of reinforcing blocking members 68 secure and support the frame members 62 along the length thereof. Further support is provided by gussets 70 attached to either side of at least the centermost blocking members 68 closest to the main folding cylinder 38. Two upright triangularly shaped beams 72 pivotably attach to the inside of the two frame members 62 and extend upward therefrom. The upright beams 72 are secured to the inside of the frame members 62 with elongated bolt and nut fasteners 71 that pass through the frame members 62 as well as the bottom of the upright beams 72. The connection allows the upright beams 72 to pivot at the juncture with the frame members 62.

A support beam 74 pivotably attaches to the top of the two triangular upright beams 72 with elongated bolt and nut fasteners 19, which pass through the upper ends of the triangular beams 72 and through collar tubes 73 on the end of the support beams 74. A cotter pin 15 further secures the elongated bolt and nut fasteners 19. The support beam 74 is the point of connection between the linkage assembly 56 and the table 30. Collar brackets 76 pivotably attach with conventional nut and bolt fasteners through bracket holes 13 in the ends of the support beam 74 and then latch to the underside of the table 30 for this purpose. The collar brackets 76 detach and then are inserted through holes in collars 95 located on either side of the under side of the table 30, thereby locking the table to the support beam 74 (see FIGS. 19, 20). Together the support beam 74, triangular beams 72, and frame members 62 form the modified 4-bar linkage 34.

Additionally, an upright bar 60 pivotably mounts to one of the upright beams 72, through the side of one of the beam members 62. The elongated bolt and nut fasteners 71 pass through the upright bar 60, a collar 45, the beam member 62, and the bottom of the upright beam 72 to form the pivoting connection (see FIG. 6). The opposite end of the upright bar 60 pivotably connects to a linkage arm 61 with bolt and nut fasteners 57. The upright bar 60 and linkage arm 61 also attach to a bracket plate 78 secured to the support beam 74. The opposite end of the linkage arm 61 secures to the upper ear 69 of the pivot lever 66 with fastener 130.

The main folding cylinder 38 attaches to the end of the bracket plate 78 extending laterally outward from the support beam 74 with conventional nut and bolt fastener. The opposite end of the main folding cylinder 38 connects to the bracket plate 75 secured to a support plate 9 extending from the side of the support beam 74.

The table angle cylinder 40 secures to a bracket plate 77 secured to one of the frame members 62, and then extends upward to connect to the underside of the table 30 by attaching at to the back side of hook plate 33 (see FIGS. 13, 20). In particular, spacers 79 insert between the inside prongs of the bracket 77 and the outside of the connector on the bottom of the table angle cylinder 40. A pin 81 inserts through the bottom of the table angle cylinder 40, the spacers 79, and the bracket 77 to secure the cylinder 40. A cotter pin 83 then secures the pin 81. The upper end of the table angle cylinder 40 secures in a similar manner by utilizing a bracket 85 and pin 87 that pass through an opening 89 in the top of the table angle cylinder 40, and through holes in the sides of the bracket 85. The bracket 85 secures to the table 30 by attachment to the back side of the hook plate 33 with nut and bolt fastener 91. The table angle cylinder 40 also includes a cylinder lock 98 for use in preventing movement and damage to the cylinder 40 during transportation of the lift mechanism 10. The cylinder lock 98 secures to the table angle cylinder 40 with fastener 132. The fastener 132 passes through holes in the sides of the cylinder lock 98, and through a hole in the center of the table angle cylinder 40.

Shown best in FIG. 11, the hitch assembly 64 will now be described. The hitch assembly 64 includes a hitch 18 that allows for attaching the table extension 10 to a towing vehicle. The hitch 18 includes two plates 82 separated by a narrow channel therebetween. The plates 82 include upper and lower holes 84, 86 for attachment of the structural components of the hitch assembly 64. In particular, the hitch assembly 64 includes a three beam triangularly shaped yoke 88 that connects the hitch 18 and the frame members 62 of the linkage assembly 56. The yoke 88 secures to the hitch 18 with a fastener 90. Holes 92 in the end of the yoke 88 align with the lower holes 86 in the hitch 18, the fastener 90 and a cotter pin 93 then secures the connection. The yoke 88 is pivotably attached to the frame members 62 and held in place between upper and lower channel plates 94, 96 shaped to capture the cylindrical beam 89 of the yoke 88. The plates 94, 96 are then secured to each other with convention nut and bolt fasteners 100. The upper plate 94 is rigidly attached to the frame members 62 by plates 102 welded thereto. A tierod 104 located above the yoke 88 secures on one end to the hitch 18, and on the other end to a collar 106 located in the center of the upper plate 94. The tierod 104 includes holes 110 on either end for attachment. A pin and connector 108 extends through one of the holes 110 in the tierod 104 to secure the tierod 104 to the collar 106. A similar connector (not shown) extends through the other hole 110 in the tierod 104, and through the upper holes 84 in the two plates 84 of the hitch 18, wherein the tierod 104 fits in the channel located between the two plates 82. A collar 112 is attached to the yoke 88 and includes a hole 114 to secure to a bracket 116 located on one end of the hitch height cylinder 42. A pin and connector 118 secures through the hole 114 in the collar 112 and through holes in the bracket 116 of the hitch height cylinder 42. The other end of the hitch height cylinder 42 secures to a bracket 120 located on one of the frame members 62 of the linkage assembly 56. A cylinder lock 122 is provided to lock the hitch height cylinder 42 in place when the table extension 10 is in the transport position. The hitch height assembly 64 also includes a protective bumper plate 134 located on the upper channel plate 94. An upright post 135 extends upward from one of the frame members 62 and provides support to the underside of the table 30 when the table extension 10 is in the bagging position.

Operation of the table extension 10 begins in the transport position. The table extension 10 should be positioned adjacent the agricultural bagging machine 12, and remain attached to the towing vehicle. A power source is then attached to the 4-bank hydraulic manifold 44 to provide operational control of the various hydraulic cylinders of the table extension 10.

Next, the table angle cylinder lock 98 and the hitch height cylinder lock 122 are removed to allow for release of the cylinders 40 and 42. The table cylinder 40 is then retracted to move the table 30 from its transport position to a more horizontal position. The main folding cylinder 38 is then retracted to begin movement of the linkage assembly 56 and the axle assembly 46 into the bagging position. Retracting the main folding cylinder 38 moves the table 30 toward the forward end 20 of the table extension by pivoting the modified 4-bar linkage 34 in that direction. This moves the center of the weight of the table 30 off of the wheels 50, where it is when the table extension 10 is in the bagging position, toward the center of the lift mechanism 14 and lowers the table 30 as the triangular beams 72 move from a vertical position to a more diagonal position. Retraction of the main folding cylinder 38 also begins moving the axle assembly 46 because of the connection of the upright beam 60 and the linkage arm 61 to the bracket plate 78. Specifically, the linkage arm 61 is connected to the upper ear 69 of the lever plate 66, which as the linkage assembly 56 begins to move toward the forward end 20 of the table extension, will begin to rotate the lever plate 66 as well as the pivot bar 53 of the axle assembly 46 which in turn causes the movement of the axle assembly 46 out from under the table extension 10 and toward the rearward end 26 of the table extension 10.

Next, the collar brackets 76 are then inserted through the holes in the collars located on the underside of the table, and latched to secure the table to the support beam 74. The position of the table extension 10 can be precisely adjusted so that the hook plates 33 are centered over the nose tube 27 of the conveyor 11 of the agricultural bagging machine 12. The table extension 12 can then be further lowered into position by retracting the axle lift cylinder 36 and the hitch height cylinder 42 until the hooks 33 fully engage the nose tube 27. Retracting the axle lift cylinder 36 moves the axle assembly 46 further out from under the table extension 10 and toward the rearward end 26 of the table extension 10. This is accomplished in a manner similar to that described above in reference to retraction of the main folding cylinder 38. One end of the axle lift cylinder 36 is attached to the lower ear 67 of the pivot lever 66. After retraction of the main folding cylinder 38 the pivot lever 66 will have rotated counterclockwise from the poison shown in FIG. 6, and will be generally held in place thereby. Retraction of the axle lift cylinder 36 will cause the axle assembly 46 to rotate counter clockwise as well, thus raising the wheels 50 off of the ground and into the position shown in FIGS. 2, 16, and 17.

Next, the table angle cylinder 40 can be adjusted to appropriately level the table 30 and bring the hooks 33 into full engagement with the nose tube 27, and the lift mechanism 14 is level under the table 30. The power source is disconnected from 4-bank hydraulic manifold 44 and released from the towing vehicle. The towing vehicle is then moved away from table extension 10 and agricultural bagging machine 12 bagger. The rings 41 can then be locked into place to secure the table 30 to the nose tube 27 of the agricultural bagging machine 12. The side panels 23 of the table extension 10, and the side panels 23 of the agricultural bagging 12 can be raised and locked into place. Finally, hydraulic hoses can be connected to the motor 28 to power the table 30. The system is capable of operating the motor 28 and the motor on the conveyor of the agricultural bagging machine 12 in series from a central control panel of the agricultural bagging machine 12.

Converting from the bagging position to the transport position essentially requires reversing the process. The hydraulic attachment to the motor 28 is removed, and the side panels 23 of the table extension 10 lowered. The table extension 10 is then unlocked from the nose tube 27 of the conveyor 11 of the agricultural bagging machine 12, by removing the rings 41. The towing vehicle can then be connected to the hitch 18 of the table extension 12, and hydraulic power connected to the 4-bank valve manifold 44. The table 30 can then be raised off of the nose tube 27 of the conveyor 11 of the agricultural bagging machine 12 by extending the axle lift cylinder 36 and the hitch height cylinder 42 until the hooks 33 are clear of the nose tube 27 and the wheels 50 are in contact with the ground.

The table extension 10 can then be transported, however, only short distances. If bagging operations are to continue at the same site the table extension 10 can be transported as needed. If the table extension 10 needs to be transported any substantial distance, complete transition to the transport position will need to be completed.

To complete transition, the table 30 should be unlocked from the lift mechanism 14 by removing the collar bracket 76. The axle lift cylinder 36 and the hitch height cylinder 42 can be fully extended. The main folding cylinder 38 should be extended to move the axle assembly 46 and wheels 50 fully under the lift mechanism 14, and to begin raising the table 30 off of the lift mechanism 14. Next, the table angle cylinder 40 is extended to place the table 30 in the transport position (see FIG. 1). The cylinder locks 98 and 122 should be engaged. Finally, the hydraulic connection can be removed from the manifold 44.
