摘要:
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.

A wide pick-up for a baler includes a crop feed rotor and auger arrangement located at an elevated position rearward of a tined pick-up reel arrangement. Positioned for receiving crop delivered by the reel arrangement, and extending beneath the crop feed rotor and auger arrangement is a crop guide plate arrangement including a central movable crop guide plate portion mounted to be moved vertically between a raised feed position, wherein it is relatively close to a circular path traced by the outer peripheries of the crop feed rotor and the converging augers, and a lowered, crop unplugging position, wherein it is spaced to create a gap between the crop guide plate portion and the crop feed rotor and auger arrangement. Right and left, primary crop stripper plates are respectively mounted to right and left front end regions of the moveable crop feed plate portion, with the primary stripper plates each having an edge located close to the associated auger for preventing crop from being wrapped about the augers when the movable crop guide plate portion is in its normal raised operating position. Right and left secondary crop stripper plates are respectively mounted to right and left fixed walls extending upwardly about the augers from right and left fixed guide plate portions, these secondary stripper plates remaining in place to strip crop from the augers when the central movable crop guide plate portion is lowered.

An agricultural machine having a crop pick up section, a crop chamber, and a crop repositioning device. The crop chamber has an opening and the crop repositioning device receives crop material from the crop pick up section and assists in the delivery of the crop material to the opening. The crop repositioning device is configured to reposition at least a portion of the crop material dependent upon the detected crop material distribution in the crop pickup section, the detected crop material distribution in the opening and/or the detected crop material distribution in the crop chamber.

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.

This cylindrical bale-forming press comprises sets of belts, bands or the like which define a chamber for forming a bale by rolling up crop products. At least one stationary roller drives the belts and is itself driven from a main drive shaft. Some of the guide rollers are movable and are subjected to a biasing action by hydraulic cylinders so as to maintain the belts under tension. According to the invention, a torque sensor is provided on the main drive shaft of the press and operates to provide an electrical output signal which is operatively connected to electrically responsive valve means in the hydraulic circuitry for controlling the hydraulic cylinders so as to reduce or eliminate the tension in the belts when an excessive resisting torque on the main driving shaft is sensed. In one embodiment wherein the hydraulic cylinders are associated with an expansion valve, the torque sensor is operatively connected to the expansion valve so as to lower the threshold of response of the valve in response to an excessive torque being sensed. According to a variant, an electrically responsive shunt valve which is movable to a position wherein it interconnects the opposite ends of the hydraulic cylinders may be connected in parallel with the hydraulic cylinders for actuation in response to the output signal of the torque sensor.

A wrapping means tensioning device is provided for a round baler and comprises an idler assembly and an application assembly. Wrapping means, like net, when drawn during a wrapping cycle acts onto the idler assembly, which in turn will press an application element of the application assembly against a roll, on which wrapping means is stored. This provides for proper tension during a wrapping cycle without the need for springs or the like, the force of which would need to be overcome, when a wrapping device is brought into a non-operative loading mode.

A large round baler has a pickup including a tined reel mounted beneath an inlet at the bottom of an expansible baling chamber for picking up windrowed crop and delivering it into the inlet. The teeth of the tined reel are constructed so as to be in the neighborhood of at least two times stiffer than conventional teeth for the purpose of enhancing bale starting and diminishing plugging by effecting a constant smooth delivery of crop to the baling chamber. An embodiment is disclosed wherein ultra-stiff teeth, teeth which are so stiff as to be virtually inflexible, are used at selected areas across the width of the reel together with the stiff teeth.

A large round baler includes mechanism for optionally wrapping a bale with either twine or a surface wrap material. A wrap control mechanism includes means whereby the wrapping process is initiated in response to a bale reaching a desired diameter within the bale chamber. Various microswitches are strategically mounted so as to be operated by various components of the twine and surface wrap mechanisms and the control mechanism therefor. These switches are integrated into an indicator circuit including indicator devices including various colored lights and a buzzer all of which are caused to operate in various modes to apprise an operator of when the wrapping process is beginning, whether or not twine or surface wrap material is present, when wrapping is complete and when the surface wrap material has been severed.
