Abstract:
The baling chamber of one type of round baler is defined by belts which are trained over rolls connected to a drive. Stones can enter the nip formed between the belts and some of the rolls, e.g., a lower front belt driving roll, and thereby cause poor tracking of the belts. To reduce the problem, a shield device is snap-fit mounted on the roll. The device includes a nip bridging plate an upright portion of which abuts the belt run advancing to the nip and a downwardly sloping lower portion of which bridges the nip. Thus the device covers the nip preventing access to it by the stones, and stones which fall upon it slide down the sloping portion of the plate eventually to find their way harmlessly to the ground.
Abstract:
A combined large round baler and whole bale wrapping apparatus includes a wheeled chassis carrying and extending between the baler and the wrapping apparatus and including tandem wheels carried at opposite ends of walking beams. A lower region of the baler is secured to the front of the chassis. First and second braces are fixed to, and diverge upwardly from, a fore-and-aft middle location of the chassis respectively to the hinge joint between the front and rear sections of the baler and a wrapping arm assembly. A tie-bar extends between the two braces. The wrapping apparatus includes a wrapping table mounted to the chassis for fore-and-aft movement between a receiving position, wherein it is disposed for receiving a bale formed by the baler, and a wrapping position, wherein it is located centrally below the wrapping arm.
Abstract:
A large round baler having an expansible bale chamber has tension cylinders associated with the chamber for strongly resisting expansion thereof so as to produce dense bales when a bypass valve located in a bypass line interconnecting rod and piston ends of the tension cylinders is positioned for preventing flow through the valve thereby forcing the flow to go through a variable high pressure relief valve located in another bypass line, the bypass valve being selectively shiftable to another position for permitting free flow therethrough when it is desired to produce a soft bale. The baler also includes gate cylinders for opening and closing the discharge gate of the baler. These gate cylinders are connected in circuit with the tension cylinders and the bypass valve is connected to the piston ends of the gate cylinders in such a way as to prevent the gate cylinders from extending at a time when the gate has just been closed, such extension of the gate cylinders, if not prevented, resulting in the gate becoming unlatched.
Abstract:
A round baler includes an expansible, upwardly converging wedge shaped bale chamber having an opening at its bottom and being formed in part by first and second belt runs that respectively converge upwardly from first and second belt support rolls respectively located at the front and rear of the inlet opening. Expansion of the baling chamber works against a downwardly biased tensioning frame pivotally mounted to opposite side walls, the first and second belt runs extending between a fixed and a pivotal roll carried by the frame with the pivotal roll being controlled to move closer to the fixed roll as the tensioning frame is forced upwardly by a growing bale. A fingered rake structure bridges the gap between the fixed and pivotal rolls to keep crop material from exiting the chamber. A crop braking structure is mounted above the first belt support roll and includes fingers projecting downwardly between the belts of the first run of belts and into the opening to the chamber to impede the flow of crop being carried downwardly by the first run of belts. An alternate feeding structure may be mounted to the baler below and rearwardly of the first belt support roll and includes feeding lugs extending through slots defined by stripper vanes, the vanes having ends of the crop braking fingers received therein and cooperating with the fingers to form a smooth crop engaging surface.
Abstract:
A baling maching includes a variable volume baling chamber with which there is associated a hydraulic tension cylinder containing fluid in its rod end for resisting expansion of the baling chamber. A high pressure relief valve is connected in circuit between the opposite ends of the cylinder for permitting fluid transfer between the ends in accordance with the pressure setting of the valve. A low pressure relief valve is connected in circuit between the opposite ends of the tension cylinder so as to be in parallel with the high pressure relief valve. A mode select valve is located in circuit between the tension cylinder and the low pressure relief valve and is shiftable between a dense bale position wherein it prevents flow from the rod end of the tension cylinder to the low pressure relief valve whereby fluid exchange between the opposite ends of the tension cylinder is by way of the high pressure relief valve, and a soft bale position wherein it allows fluid to flow freely from the rod end of the tension cylinder to the low pressure relief valve whereby fluid exchange between the opposite ends of the tension cylinder is by way of the low pressure relief valve.
Abstract:
A round baler of the non-stop type has three arms rotating about a common axis and having rolls at their free ends. A loop may be formed between the rolls of the same arm, whereas a small loop is created, by way of which the start of a bale core can be achieved.
Abstract:
A baler and wrapper combination comprises a baler, a bale wrapper, and a bale transport table. The bale transport table is movable between a bale receiving position at a bale output location of the baler, a wrapping position at which the wrapper can wrap a bale located upon the bale transport table with a sheet material, while movable bale support elements rotate the bale around its horizontal central axis, and a bale depositing position in which a wrapped bale can be deposited on the ground. The bale support elements are arranged to be moved in the bale depositing position into an orientation in which the bale is deposited on its flat end.
Abstract:
A round baler of the non-stop type has three arms rotating about a common axis and having rolls at their free ends. A loop may be formed between rolls of adjacent arms, wherein material is fed to the loop forming a bale from one of several outlets fed by a feeder.
Abstract:
A round baler has an overshot secondary rotor located behind an undershot precutter rotor. The round baler has a relatively wide swath crop pick-up and a baling chamber with a significantly more narrow inlet. The precutter rotor has a central region supporting a plurality of rotatable crop conveying members interleaved by both a set of relatively fixed cutting blades and a set of relatively fixed strippers for urging cut crop away from the rotor, and end regions supporting rotatable helically disposed bands for receiving wide swath crop from the pick-up arrangement and urging the received crop toward the central region. The secondary rotor creates an S-shaped or serpentine crop path with minimal dead space and is a positive feeder for bale starting. Stationary strippers for the secondary rotor prevent crop from exiting the baler behind the secondary rotor.
Abstract:
A baler comprises a baling chamber and a sensor arrangement. The sensor arrangement comprises at least one sensor arranged to provide information about a mechanical property of a bale built in the baling chamber and a control unit receiving signals from the sensor. The control unit is operable to automatically calibrate the signals from the sensor based upon at least one signal from the sensor received in at least one known state of the sensor.
