摘要:
A round baler has a bale chamber surrounded by bale forming means running over stationary and moveable rollers. Some moveable rollers are carried by arms which are located outside opposite side walls of the bale chamber. This enables a bale to be formed within the spacing between the side walls and to be ejected by raising the arms carrying moveable rollers to open the bale chamber.

A large round baler includes a pick-up which delivers crop to a transport assembly including a guide wall and tined rotor, together with a rotor stripper, which cooperate to move harvest material from the pick-up to the inlet of a baling chamber. Various embodiments are disclosed for moving one or more of the guide wall, rotor or stripper for effecting adjustments narrowing or expanding the cross section of a guide channel for the harvest material defined in part by the guide wall, rotor and stripper. These adjustments can be done manually or with power and can be made in response to computer generated information or command signals resulting from collected and/or stored data indicating various conditions of the harvested material.

A large round baler, designed as a non-stop baler, includes a mobile chassis supporting a lower baling chamber section, defined by a floor conveyor arrangement, and an upper baling chamber section. The upper baling chamber section, together with opposite side walls, is mounted for fore-and-aft movement relative to the lower baling chamber section between a rear location, wherein it cooperates with the floor conveyor arrangement to define a rear baling chamber, and a front location wherein it cooperates with the floor conveyor arrangement to define a front baling chamber. The upper chamber section includes front and rear wall portions which are mounted for being raised once a bale is formed in the rear baling chamber so that the upper section may be moved to its forward location. A wrapping device is provided which is operable once the upper chamber section is moved to its front location, for wrapping the bale with overlapping wraps of sheeting made from plastic or the like so as to provide an air tight casing for the crop material so as to make silage.

The bale-forming belt for wrapping crop upon itself to form a cylindrical bale within a baling chamber of a round baler is automatically maintained in a straight tracking condition, despite an uneven supply of crop entering across the width of the baler, by a tracking control that is responsive to uneven tension across or the mistracking of the belt for effecting radial adjustment of one end of one or more of the rolls supporting the belt.

The binder twine arm arrangement includes two arms having twine dispensing ends. The arms initially remain in a rest position wherein their dispensing ends are near a first end face of a bale to be bound. The arms are moved to a start position wherein the dispensing ends are located centrally between the first end face and a second end face of the bale. The arms are then actuated or controlled such that they first spread apart and then return together about a hinge joint interconnecting the two arms. Upon returning to the start position the arms are returned to the rest position. For this purpose, an actuator is provided between the two arms which becomes active to effect relative motion between the arms as soon as the arms have reached the start position.
摘要:
A baling machine for forming large cylindrical bales of hay has a variable volume bailing chamber defined by moving belts with a crop inlet on the underside of the machine. When a bale has been completed it is wrapped with net stored in a holder on the back of the baler. The net is advanced by feed rolls through a cutting mechanism below the holder, and is then guided by a plate extending along the underside of a run of the belts to the baling chamber. The plate is in such close proximity to the run that the net is gripped between the plate and belts and is advanced by the moving belts. Finally, the net is cut by the cutting mechanism, the wrapping of net completed, and the bale discharged rearwardly through a gate onto the ground.
摘要:
A baling machine for forming large cylindrical bales of hay has a variable volume baling chamber defined by moving belts with a crop inlet on the underside of the machine. When a bale has been completed it is wrapped with surface wrapping material stored in a holder on the back of the baler. The wrapping material is advanced by feed rolls through a cutting mechanism below the holder, and is thus guided by a plate extending along the underside of a run of the belts to the baling chamber. In order to avoid wasting wrap, a cutter is triggered by a peg carried by a metering wheel movable between an adjustable "home" position against an abutment or stop to a trigger position in which it engages and lifts a release lever to release the cutter, and this distance is a measure of the length of wrap material required for the completed bale. In respective embodiments, the metering wheel is in the form of a friction wheel, a worm wheel and a ratchet wheel with all wheels being selectively driven by one of the feed rolls.

A cylindrical baler is comprised of an adjustable bale-forming chamber for forming spirally wound, cylindrical bales. A completed bale is discharged on the ground through a rear gate. The chamber is comprised of a plurality of longitudinally extending, side-by-side belts supported on a plurality of transverse rollers. The chamber is adjusted by a pair of belt tension rollers engaged with the bale chamber belts and supported between a pair of pivotally mounted belt tension arms which are displaceable as the diameter of a bale in the chamber increases during formation. A hydraulic circuit controls the tension applied to the chamber by the belt tension arms and rollers and also operates the bale discharge gate. A pair of hydraulic jacks are, respectively, mounted on each side of the baler and connected between the bale discharge gate and the belt tension arms. To properly tension the belts, a nonreturn valve isolates the hydraulic jacks from the tractor's hydraulic supply and the jack chambers are connected in closed circuit through an adjustable pressure valve to apply a resistance to fluid flow from one chamber of each jack to the other. The nonreturn valve is pilot controlled and is opened to permit return fluid flow to the tractor supply when the jacks are actuated to open the rear gate. Thus, each jack performs a double function of braking the movement of belt tension arms and rollers and operating the bale discharge gate, thereby, providing a simple, low cost, hydraulic circuit for belt tensioning and gate operation.

A baler is comprised of a plurality of rollers and two sets of belts supported on the roller and defining a bale-forming chamber for rolling crop material into a cylindrical bale. A guide is mounted on the exterior of the bale-forming chamber and generally parallel to its longitudinal axis. A control wheel is mounted on a support means for mounting the wheel on the guide for movement about an axis perpendicular to the longitudinal axis of the chamber. By movement of the guide, the control wheel may be moved into and out of contact with one set of the belts. The support further carries a twine guide for guiding the entry of twine into the bale-forming chamber during movement of the support to and fro along the transverse guide. The movement of the wheel about the axis perpendicular to the longitudinal axis of the chamber controls the direction of displacement of the support along the guide when the control wheel is engaged with the set of belts.

A baffle arrangement is provided for a harvested crop recovery machine such as a baler. The baffle arrangement has two baffles that follow each other in the direction of the flow of the crop. The upstream baffle is configured in the form of a rake and permits harvested crop lying upon it to fall back into the flow of the crop. A second baffle following the above baffle is configured as a deflector plate having a substantially closed surface and extends above an overshot conveyor in order to conduct harvested crop lifted by it with a minimal amount of friction and prevents the harvested crop from leaving the flow of crop.
