Abstract:
A round baler is provided having a bale chamber that is partly covered by stationary side walls assuming the size and shape of the bale chamber and by a gate having a skirt which can be brought into an overlapping relationship with the side walls when the gate is closed.
Abstract:
An actuating mechanism for the functional elements in a round baler for agricultural crops includes a tensioning arm which is provided with guide rollers and a pivotal arm and which is pivoted on the frame of the baler via a hydraulic cylinder. The hydraulic cylinder is arranged between the pivotal arm and a first arm of a bell crank, which is pivotally mounted on the tailgate. A second arm of the bell crank is selectively engageable with the front part of the housing.
Abstract:
A baler including a plurality of endless belts and opposing side walls defining therebetween a chamber for receiving forage material and forming a bale. Each of the belts is formed as a full width belt extending substantially a transverse distance from one of the side walls to the other of the side walls. In order to maintain proper tracking of the full width belts, a drive roller for each of the belts is formed with a sleeve centrally located on the drive roller and defining a crown for the roller, as well as improving traction between the roller and the belt. In addition, each of the full width belts is formed with a differential stiffness wherein the belt exhibits a greater stiffness against bending about an axis perpendicular to the rollers than the stiffness against bending about an axis parallel to the rollers. In order to facilitate removal of debris from an area adjacent to an inner surface of the belt, a roller for guiding the belt is provided with a helix structure wherein the helix acts as an auger to convey debris away from the center and toward the ends of the roller.
Abstract:
A latch assembly for a cylindrical baler for latching a bale discharge gate to the front section of the baler. The bale discharge gate is moveable by a hydraulic cylinder back and forth between a closed position for bale formation and open position for bale discharge. The latch assembly includes a latch member fixed to the front section of the baler; a latch hook, for engaging the latch member, pivotably mounted to the gate; and an actuator arm connected between the latch hook and the hydraulic cylinder for engaging and disengaging the latch hook with the latch member responsive to the retraction and extension of the cylinder. The improvement comprises a resiliently biased slidable connection between the latch hook for permitting the actuator arm to be moved responsive to the retraction of the cylinder plunger even though the latch hook may be restrained from movement due to misalignment of the latch hook with the latch member.

Abstract:
Apparatus is presented for slicing a large round bale into two or more parts prior to discharge from the baler. Slicing is accomplished by inserting a knife blade into the bale-forming chamber during or subsequent to the tying-off event while the bale rotates. The cutting means is inserted into the sidewalls of the baler and into the baling chamber. As the bale is rotated, the cutting means cuts the bale. Typically, a ring and core are formed. The preferred configurations of the core are cylinders or conical structures.
Abstract:
An ejection mechanism is described which automatically assists in the discharge of completed bales from the bale-forming chamber. As implemented the ejection mechanism forms a part of a baler which produces generally cylindrical bales in a chamber of fixed size having closed sidewalls adjacent the ends of the bale. The baling chamber is divided into two parts with one portion being hinge mounted along its front edge to allow its second or rear edge to swing open upwardly to provide a gate through which completed bales can be discharged. The second portion of the baling chamber contains a bottom conveyor for imparting rotational motion to the bale during the crop gathering and bale forming process. When the bale in the chamber is completed and ready for discharge, the gate swings open and the bottom conveyor continues moving in a front to rear direction. Simultaneously with the opening of the gate, bale contacting means are applied at the top edges of the bale to introduce a coupling force which tends to stop the bale from turning in place, thereby enabling the bottom conveyor to transfer the bale out the gate of the machine.
Abstract:
To form round bales of fibrous agricultural material, windrowed material is fed into a baling zone formed within a frame. The frame is formed of a stationary front part and a rear part pivotally connected to the front part. Circumferential peripheral surface of the baling zone is lined with conveying elements, either belts, chains, drums, rollers or the like can be used. The material enters in the lower portion of the front part through an opening between two adjacent conveying elements. As it is carried along by the conveying elements, the material is turned over on itself gradually producing a round bale limited in size by the circumferential periphery of the baling zone. As the zone becomes filled, the conveying elements compress the material, wherein the inner layers foist together in a stellate manner. When the bale is completed the rear part pivots away from the front part to discharge the bale.
Abstract:
A crop collection vehicle can be coupled to a prime mover for movement over the ground to collect and move crop to a desired site. A pick up and feeding mechanism at the front of the vehicle feeds crop to a chamber that is defined by a forward wall, a rear wall, side walls and a top. The chamber is enlarged with its walls bulged outwardly and a conveyor system within the chamber is positioned to receive and move crop received from the mechanism towards the rear of the chamber. The conveyor system includes a floor conveyor that slopes downwardly to the rear and articulated conveyors that coextend upwardly with a portion of the rear wall. The latter portion can be tilted together with the articulated conveyors to a downwardly extending position so that crop received from the floor conveyor can be formed and discharged as a coherent mass of crop intact. The rear wall and top of the chamber can be tilted by hydraulic piston assemblies and the mechanism together with conveyor system can be driven from the p. t. o. of the prime mover. A feeding device formed by cooperating opposing drums with tines that are moved to active crop loading positions is located at an entrance of the chamber so that crop is fed from between the drums through the chamber entrance. Alternatively, the feeding device can be reciprocating tine supports that progressively feed crop from a pick up to the floor conveyor. The conveyors of the system can be driven intermittently from a drive connection between the feeding device and the floor conveyor.
Abstract:
A tailgate latching mechanism for a round bale that utilizes action of the tailgate lift cylinders to release the latch to allow the tailgate to be opened and an independent spring action to cause the mechanism to catch and latch the tailgate into position upon closure of the tailgate.
