This application is a continuation of U.S. patent application Ser. No. 13/369,230 filed Feb. 8, 2012 which is incorporated herein for any and all purposes.
FIELD OF THE INVENTIONThe embodiments of the present invention relate to a mobile hay press configured to compress conventionally baled hay into smaller packages for shipping.
BACKGROUNDHay is conventionally baled using a large vehicle known as a hay baler. In general, the hay baler uses a device known as a pickup to harvest the hay. The pickup comprises a series of metal bands on a spool that rotates as it passes over the hay along with the hay baler moving over a field of hay. After the hay is harvested by the pickup, the hay is transported to a connected baler that presses the hay into a bale and cuts the bale to size. The hay may be compressed by a spring mechanism and packing arm that moves back and forth as hay is collected inside of a bale chamber. When a complete bale is made, the baler ties the bale with twine and ejects them to the field. Square bales are built in many different sizes. In one embodiment, the apparatus disclosed herein accommodates, without additional pre-processing, and in an un-ground or un-chopped state, bales of 3′×4′ cross section with lengths of 6′ to 9′ and also 4′×4′ cross section with lengths of 6′ to 9′. As described, the aforementioned bales weigh between 700 and 2500 pounds. The apparatus can also accommodate any size or shape bale that is first ground or chopped into a loose state and then repressed by the apparatus by first loading the ground or chopped hay into a loose hay loading chamber also incorporated into the apparatus.
With increased hay exports, it would be advantageous to develop an apparatus for compressing conventional hay bales making them more suitable for shipment. Ideally, the apparatus would be mobile allowing it to be transported to the source of the hay bales.
SUMMARYAccordingly, a first embodiment of the present invention comprises an apparatus (termed a “hay press”) configured to generally (i) receive hay bales; (ii) cut the twine holding the hale bales together; (iii) move, by weight, a pre-established amount of loose hay into a compression chamber; (iv) compress the pre-established amount of loose hay into a package of pre-established size; and (v) eject and wrap the compressed package of hay for shipping. In one embodiment, the original hay bale having a 3′×4′ or 4′×4′ cross section is compressed into a 35″ high by 49″ long package of hay varying in width from 40″ to 44″.
In one embodiment, the hay press comprises a (i) loading table and destacker; (ii) twine slicer; (iii) loading compartment; (iv) loading hydraulic press and platen; (v) in-feed forks; (vi) compression chamber; (vii) scale; (viii) compression chamber door; (ix) hydraulic compression ram and platen; (x) hydraulic ejection press and platen; and (xi) ejection chute. Other elements and features may be present as described in detail below.
In one embodiment, the hay press is supported by a frame on wheels such that the hay press is mobile allowing it to be transported to sources of hay bales. A hitch member integrated with the frame allows the frame to be connected to a truck or similar vehicle which can then tow the hay press to any desired location. The unique in-line configuration of the hay press allows the hay press to be transported in one piece.
Other variations, embodiments and features of the present invention will become evident from the following detailed description, drawings and claims.
For the purposes of promoting an understanding of the principles in accordance with the embodiments of the present invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive feature illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention claimed.
The embodiments of the present invention are directed to a hay press which may be fabricated of known materials such as metals, alloys, composites and fasteners such as screws, rivets and welds. Those skilled in the art will recognize that any suitable materials and fasteners may be used to fabricate the hay press detailed below.
Once the hay bale 101 is loaded into the loading chamber 120, as shown in
As shown in
Opening and closing the compression chamber door 150 is accomplished using one or more hydraulic rams 146 to drive upward one or more arms 147 and linkage 148 connected to a door lift 149.
The compression chamber 140 is defined in part by a bottom 141, top 142 and the compression chamber door 150. The platen 170 of the hydraulic ejection press 165 and the platen 160 of the hydraulic compression ram 155 serve as two more sides of the compression chamber 140. A fourth and final side 143 of the compression chamber 140 includes in part a previously compressed hay package restrained in the ejection chute 175 by friction between the package and the ejection chute walls and extending from said compression chamber 140.
After the compressed hay is ejected and packaged, a second scale 177 weighs the compressed hay package. The compressed hay package is hand labeled, bar-coded or RF tagged to allow each compressed hay package to be tracked. The compressed hay package is then transported by rollers 180 or conveyor belts onto a stacking table 185 that indexes and stacks the compressed hay package to form a 2×2 compressed hay package arrangement which may be picked up and loaded by a forklift or similar device into a shipping container. In another embodiment, the stacking table 185 is controlled by hydraulics or similar technology allowing the stacking table 185 to directly load the compressed hay packages into a shipping container.
A control panel 190 allows a single operator to control the hay press 100. The control panel 190 utilizes touch screen technology along with other user interface means and relies on proprietary software to facilitate the desired hay press actions according to the instructions input by an operator.
In another embodiment, a conveyor system 191 handles loose hay thereby limiting clean-up and general labor related to the operation of the hay press 100.
The embodiments of the present invention involve multiple advantages including mobility allowing the hay press 100 to be transported to the hay source rather than transporting hay to the hay press. The mobility eliminates the need for specialty facilities for receiving hay prior to access to the hay press and thereafter. The mobile hay press is ideal for small hay producers and shippers incapable or not desirous of owning a large, expensive hay press. The mobile hay press is also subject to less governmental oversights and regulations, at least for the hay producers and shippers. Another advantage is the narrow width facilitated by the inline configuration allowing the hay press to be transported on highways without significant re-configuration. Yet another advantage is the use of the compression chamber door 150 as a back wall for the compression chamber 140. Moreover, the door 150 design facilitates the inline design and allows the hay to be loaded opposite the hydraulic compression ram 155. By loading the hay opposite the hydraulic compression ram 155 and platen 160, the stroke of the hydraulic compression ram 155 and platen 160 is reduced thus decreasing the time necessary to compress loaded hay and required horsepower. That is, hay may be loaded into the compression chamber 140 as the hydraulic compression ram 155 and platen 160 are retracting from the last compression.
While not shown, the hay press 100 described herein may include numerous additional sensors to maintain a status of the hay press process such that the hay press may be stopped or otherwise manipulated if problems arise. Moreover, various tubing and piping configured to carry various fluids (e.g., hydraulic, water, etc.) form part of the hay press 100 and facilitate the process undertaken by the hay press 100.
The embodiments of the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive.
