Abstract: A pair of straw and chaff spreaders for a combine are operable to distribute straw and chaff in an even and wide spread pattern on the ground behind the combine. Each spreader has an upright shaft drivably coupled to upper and lower dishes. Flexible arms on the upper disk distribute straw. Rigid channel shaped arms on the lower disk propels chaff and small particulate materials in the pattern. The turning channel shaped arms also generate an air stream which distributes straw and chaff in the wide spread pattern.

Abstract: A spreader for granular and/or powdery material such as fertilizer comprises a hopper having two delivery parts. Distribution members are provided under the delivery parts for broadcasting material fed to them from the hopper. The distribution members are mounted on a carrier rigidly supported by the hopper. This construction results in a fixed position of the distribution member with respect to the delivery parts, regardless of deflections which may occur as a result of the weight of material in the hopper. The distribution members may be driven by a mechanical transmission from a power take-off shaft of a tractor, or by a hydraulic motor. The mechanical transmission includes a horizontal shaft connected to two vertical shafts for rotating the distribution members via bevel gears and is contained in a hollow tube with gear boxes on either end which maintain the axes and levels of the vertical shafts and distribution members in fixed relative positions.

Abstract: A straw spreader for the rear straw discharge of a combine comprises a frame mounted on ground wheels together with a pair of hitch arms which extend forwardly from the frame on either side of the rear portion of the combine for attachment to the combine frame structure. The separate frame can thus move up and down relative to the rear of the combine and maintains a pair of spreader spinners on the frame at a predetermined height relative to the ground. Guide surfaces collect the material from the chopper at the rear of the combine and direct it onto the spinners for a spreading action. The low height of the spreading action reduces dust emission and enhances spreading consistency. An accumulator can be provided between the spreader and the discharge in the rear of the combine to allow the amount of straw spread to be varied relative to the amount collected at any particular point on the field.

Abstract: A spreader for spreading granular and/or powdery materials having a hopper and rotary distribution members with ejection blades on plates located below the hopper. The areas covered by the two distribution members can be adjusted so that they substantially coincide with one another. In some embodiments, the orientation of the ejection blades on the plates can be adjusted. Material flows to the distribution members through feeding means that include outlet openings and ports that can be in register with the openings. Also, displacers or closing members for affecting this flow can be positioned near the outlets at the lower portion of the hopper. A transmission, including change speed gears, can be connected through endless flexible members, i.e., ropes or belts to the shafts mounting the distribution members.

Abstract: A device for spreading granular and/or powdery material comprising a hopper for material to be supported and at least two distributing members rotated in opposite directions about vertical rotary axes, material feeding means provided between the hopper and distributing members for feeding material from the hopper to the distributing members so that each of the two distributing members receives the material eccentrically with respect to its rotary axis; the distributing members having such shape and being drivable in a manner, and the feeding means being constructed and disposed whereby in operation material is supplied to the distributing members so that each spreads material across a sector which substantially coincides with the sector across which the other distributing member spreads material. With such a device the material is advantageously spread uniformly and different materials may be spread in the same manner without the need for readjusting various members of the device.

Abstract: A chaff spreader for attachment to a combine includes a pair of spaced circular mounting rings, each having a fan rotatably mounted therein. An elongated drive shaft extends between the fans and is connected to a belt and pulled drive system for rotating the fans. A semi-cylindrical shroud is secured between the mounting rings and partially surrounds the fans. An open side wall portion of the shroud is directed forwardly toward the sieve of the combine for inducting chaff through the fans and laterally outwardly from the combine. The belt and pulley drive system is connected to a pulley on a straw chopper section of the combine. In a second embodiment, a generator driven light is mounted on the combine, adjacent the fans to serve as a warning to indicate fan rotation. The shaft spreader collects chaff through a suction effect created by the fans and spreads chaff evenly across the width of the cut, eliminating the toxic effect to seedlings growing through a concentration of chaff residue.

Abstract: A harvester thresher is provided with a device for distributing grain-chaff mixture coming from a grain separating device over the whole width of a cutting mechanism which is generally substantially wider than the harvester thresher itself. For this purpose the housing which surrounds discs provided with distributing strips peripherally and at their one end side is provided with an additional air supply opening, so that in the region of the distributing strips a suction aspirates the grain-chaff mixture into the distributing device.

Abstract: A straw chopper and spreader assembly for receiving straw from a threshing machine, has a casing enclosing a pair of contra-rotatable flail assemblies. The flails are mounted in different horizontal planes and have blades which overlap so as to shear and chop the straw. At the rear of the casing is a rear outlet defined between a rear skirt and a bottom extension of the casing. The rear skirt is adjustble so as to enlarge or reduce the size of the rear outlet. In addition to discharge through the rear outlet, chopped straw is also discharged laterally through side chutes which have removable end portions so that discharge selectively may be outwardly and upwardly or outwardly and downwardly. Chaff spreading discs are mounted below the assembly and rotates horizontally.

A synchronizing mechanism interconnects the star wheel applicators to synchronize the speed of rotation and to assure a uniform spray pattern.

Abstract: A spreader for granular and/or powdery material such as fertilizer comprises a hopper having two delivery parts. Distribution members are provided under the delivery parts for broadcasting material fed to them from the hopper. The distribution members are mounted on a carrier rigidly supported by the hopper. This construction results in a fixed position of the distribution members (3, 4) with respect to the delivery parts, regardless of deflections which may occur as a result of the weight of material in the hopper. The distribution members may be driven by a mechanical transmission from a power take-off shaft of a tractor, or by a hydraulic motor.

Abstract: A spreader comprises four spreader members which, in operation, all spread material over substantially the same sector at the same time. The two central spreader members are lower than the two outer spreader members to avoid collisions between particles ejected from the different members. The hopper has four discharge funnels, each provided with a discharge outlet, the aperture size of which is controlled by a doser member. All of the doser members are rigidly connected together so that they move in unison and open each outlet opening initially in its central part considered in a direction transverse to the spreader's usual direction of travel. The hopper is very large, having a width of between two hundred sixty and three hundred centimeters.

Abstract: A spreader has a hopper the lower region of which comprises a wall portion which coincides in part with a sphere and contains outlet ports for material to pass at an inclined angle from the hopper to a rotating distribution member. The free aperture of each port is adjustable by a dosing slide. These dosing slides are controlled by an adjusting mechanism capable of displacing either one of the dosing slides without displacing the other.

Abstract: The spreading apparatus has a main hopper and at least one extension hopper, each having a discharge roller for flowable material such as chippings for road surfacing. The extension hopper is mounted adjacent the main hopper and movable longitudinally to enable variation of the combined width of the hoppers. A baffle cuts off communication between the discharge roller of the extension hopper and the major part of the interior of the extension hopper over a width corresponding to the longitudinal overlap between the main hopper and the extension hopper.

The movable member includes a shaft driven in rotation by a motor and flexible, moderately hard deflecting strips, which are articulated to the shaft or to a structure rigidly integral with the shaft, so as to spread out from the shaft at an angle by the effect of centrifugal force when driven in rotation. At least one discharge opening is provided in the side wall of the hopper and/or of the chute in the direction of the rotating deflecting strips.

Abstract: A method for controlling the density distribution of bulk material in the manufacture of pressed wood panels includes the step of eliminating the irregularities in the bulk material stream as it flows to the forming station. Apparatus for accomplishing this result includes a pair of spaced apart parallel rollers that define an adjustable slotted opening through which the material passes. Rotation and oscillation of the rollers function to render uniform the density distribution of the bulk material stream.

Abstract: Two spreading mechanisms disposed substantially completely across a rear outlet of a container-hopper having a movable deck, the spreader comprising a pair of two-part distribution members which rotate about vertical shafts which are disposed close to the edge of the deck. The upper part has four sets of resilient tines extending from angle irons spaced outwardly from the rotary shaft, the tines being bent at their ends and connected to the angle irons via coils whereby they are resiliently forced backward in their rotation through the fertilizer, usually manure, and when released resiliently spring forward whereby material engaged by the tines if flung outwardly. On the same shaft the lower part is a disc type ejector extending in substantial part under the moving deck to receive fertilizer which the tines miss. A freely rotatable guide member surrounds the shaft between the ejector and the tined portion to preclude material from winding around the shaft.

Abstract: A spreader suitable for spreading granular and/or powdery materials, such as seeds or fertilizer, comprises a distributor which has an upturned rim. The distributor can be driven in rotation or reciprocated about an axis which is inclined rearwardly from top to bottom at different speeds by means of a change-speed means. Frame members are orientated to prevent the least obstruction to material ejected past them by the distributor. A downwardly inclined deflector prevents material from impinging against a vehicle to which the spreader is hitched. The constructional features of the spreader contribute to an even distribution of material about the axis, regardless of the type of material being spread.
