Abstract:
A round baler for forming crop material into cylindrical bales. The baler has a main frame, a pair of side walls, a crop pickup mounted on the main frame, and a tailgate pivotally connected to the main frame. The tailgate is operative between a closed position during which a bale is being formed in an expandable chamber, and an open position during which a formed bale is being discharged from the chamber. A sledge assembly, pivotally mounted on the main frame for movement between a bale starting position and a full bale position, has crop engaging transverse rollers for urging the crop material along a spiral path in the chamber for starting and forming a bale. A apron is supported along a continuous path on the main frame and tailgate by a plurality of rotatable guide members. The path has an inner course that cooperates with the sledge rolls on the sledge assembly to define moveable walls of the chamber. A drive roll moves the apron along the continuous path. A take up assembly moves with the sledge assembly between the bale starting position and full bale position to provide slack in the apron under conditions where the tailgate is moved from its closed position to its open position.

The tailgate is operative between a closed position during which a bale is being formed in an expandable chamber, and an open position during which a formed bale is being discharged from the chamber. A sledge assembly, pivotally mounted on the main frame for movement between a bale starting position and a full bale position, has crop engaging transverse rolls for urging the crop material along a spiral path in the chamber for starting and forming a bale. A apron is supported along a continuous path on the main frame and tailgate by a plurality of rotatable guide members. The path has an inner course that cooperates with the sledge rolls on the sledge assembly to define moveable walls of the chamber. A drive roll moves the apron along the continuous path. One of the transverse rolls on the sledge has a plurality of flaps that extend into the space between and has intermittent contact with the apron as it travels in the vicinity of the outer surface of the transverse roll. This prevents leakage of stray crop material from the space between such roll and the apron under conditions where a cylindrical package of crop material is being formed in the chamber.
Abstract:
The vertical chamber of the open throat, vertical chamber baler has its bottom inlet opening devoid of a starter roll. A resilient rotary rake tine assembly positioned below and ahead of the inlet opening picks up crop material from the ground and delivers it to a rigid tooth feeder spaced below the inlet opening in vertical alignment therewith. At the beginning of each bale forming cycle when the chamber is small and empty, the rigid tooth feeder propels the crop material into the chamber and against the upwardly moving rear belt stretch which encourages the material to tumble forwardly against the downwardly moving front belt stretch. The oppositely moving surfaces presented by the front and rear belt stretches encourage the tumbling material to coil into a bale core, which ultimately forms a larger bale. In the event loose material drops through the bottom inlet opening during core starting, such material is immediately returned to the chamber by the rigid tooth feeder along with other material delivered to the rigid tooth feeder in the meantime.
Abstract:
The round baler has a plurality of transverse rolls and a plurality of laterally spaced belts entraining the rolls, wherein the rolls and belts cooperatively define a baling chamber expandable from an initial, generally upright, bale-starting configuration. The baling chamber has a crop intake opening adjacent the bottom of the chamber through which crop material is delivered to the chamber during formation of a bale. The rolls include a lower front roll and a lower rear roll which are located behind the intake opening. The lower rear roll has a bale supporting surface that is positioned generally upwardly and rearwardly from the front roll for supporting the bale during formation thereof at a point spaced upwardly and rearwardly from the intake opening. The belts include a stretch that extends generally upwardly from the front roll when the chamber is in the bale-starting configuration and shifts into engagement with the rear roll as the chamber expands, whereby the belt stretch presents a moving surface extending generally rearwardly and upwardly from the front roll to the rear roll for delivering crop material from the intake opening to the bale.
Abstract:
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 tailgate. The chamber is defined by a plurality of belts supported on a system of rollers. Tensioning cylinders are mounted on each side of the baler to provide variable bale density and tailgate cylinders are positioned on the rear of the baler to actuate the tailgate after a bale is formed. A two-way proportional valve acts alone or in cooperation with an adjustable rotary valve and an adjustable relief valve to coordinate the flow, to vary the belt tension, and to open and close the tailgate.
Abstract:
A round baler having a bale forming chamber including one or more transversely mounted rolls and at least one elongated belt having opposing ends spliced together to form a continuous band. The splice includes a first and a second series of similar side-by-side loops connected to and extending from the respective opposing ends of the belt, and an attaching element extending through the first and second series of loops to maintain the opposing ends of the belt in alignment and close proximity to each other. Retention components affixed to the attaching element retain it in operative relationship to the first and second series of loops and are disposed outwardly of the outer loops.
Abstract:
An apparatus for forming large round bales of crop material includes a frame (10) having a pair of side walls (12, 14) and ground engaging wheels (18) mounted on the frame for supporting the apparatus for movement across the ground. A plurality of rollers (24, 26, 28, 30, 32, 34, 36, 38) are mounted for rotatable movement relative to the frame (10) and extend between the side walls (12, 14), and a plurality of endless bale forming belts (46) are trained about the rollers to define a bale forming chamber (16) in which large round bales of crop materials are formed. At least one additional chamber (48) is also defined by the bale forming belts (46) adjacent the bale forming chamber (16). A clean-out assembly (54) is provided for cleaning crop material from the additional chamber. The clean-out assembly (54) includes an opening (64) in one of the side walls (12) of the baler and a clean-out belt mounted on a pair of pulleys (56, 58) for sweeping crop material in a direction toward the opening in the side wall so that material within the additional chamber (48) is swept from the apparatus through the opening (64).
Abstract:
In order to retain the press element (9) in a roll baling press (1) in a stable shape corresponding to the minimum size of the press chamber after a movable part (3) of the press has been closed, the press element (9) consists of an inherently stiff rubber or plastic web capable of forming a self-supported loop (SM) corresponding to the minimum size of the press chamber. At the beginning of the winding operation there is thus no interference by laterally disposed components, resulting in optimum operating conditions.
Abstract:
A baling machine adapted to a produce a rolled mat in the form of a bale comprises an inlet (10) for straw or other material to form the mat, a baling chamber (11) for progressively accumulating a rolled bale (41), rollers (12) for forming said straw into an elongate mat, a flow path for mat through the baling machine from the inlet (10) through said rollers (12) to the baling chamber (11), troughs (17, 18) for mounting rolls of net as encasing material adapted to supply the net progressively to the flow path so as at least to over and underly said mat, and a work station in the flow path comprising stapling machine (19) for attaching together over and underlying portions of the encasing material through said mat.
Abstract:
Instead of being bound by being wrapped with twine, wire or plastics sheeting, relatively large bales of crop formed by winding are made cohesive by pressing a pushing or penetrating member into the bales as the outer layers are formed. The pushing member forces stalks from each layer of crop into inner layers, to achieve a plaited or braided effect that keeps the bale intact.In another embodiment U-shaped binding elements are shot into the bale for holding the bale together after it has been formed.
