摘要:
A round baler having a wrapping apparatus for wrapping bales with twine includes a twine dispenser moveable generally between the sidewalls for dispensing at least one strand of twine around the bale. The wrapping apparatus further includes a retractable twine guide for spacing the twine wrapped around the bale a certain distance from one of the sidewalls. The guide is shiftable into and out of an operating position, in which the guide engages and maintains the twine the distance from the one sidewall. The operating position of the twine guide is generally within or proximate to the path of inflowing crop material so that shifting of the guide out of the operating position minimizes interference with the flow of material and reduces accumulation of trash and material on the guide.

A round baler includes bale forming mechanism and a crop delivery apparatus for delivering crop material to the bale forming mechanism. A clutch is provided for drivingly disconnecting the bale forming mechanism and delivery apparatus from the driveline while the tailgate is raised to discharge a wrapped bale. Engagement and disengagement of the clutch is controlled by a piston and cylinder assembly, and raising and lowering of the tailgate is controlled by a pair of piston and cylinder units. The baler is provided with a hydraulic sequencing circuit that connects the clutch assembly and the tailgate units to a common source of pressurized fluid. Moreover, the sequencing circuit controls fluid flow to the assembly and the units so that the clutch is disengaged before the tailgate is raised and the clutch is not re-engaged until the tailgate has been closed.

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.

The baler has a "vertical" bale starting chamber in which the upward moving rear belts and the downwardly moving front belts cooperate to tumble and roll incoming material into a bale. When the bale reaches full size in the expanded chamber, the bale is lifted while still in its chamber to a wrapping station where it continues to spin as a binding wrapper is applied. During the lifting of the finished bale and subsequent application of the wrapper, fresh material entering the continuously moving baler is confined beneath the finished bale in a new starting chamber, whereupon the cycle is repeated. As the new bale grows, a discharge ramp becomes formed by certain stretches of the belts and rollers to gravitationally discharge the wrapped bale from the baler without stopping advancement of the machine.

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.

A round baler includes a tension assembly for applying pressure evenly across the periphery of the bale as it grows within the baling chamber. The tension assembly includes a rotatable torque tube extending between the sidewalls and only one tensioning mechanism, such as a hydraulic cylinder, adjacent one of the sidewalls of the baler for supplying a yieldable resistance load in opposition to torsional loads on the torque tube. A load transferring member extends inwardly from the one sidewall to operably connect the single tensioning mechanism to the torque tube at a location spaced between the sidewalls and thereby transfer the loads between the mechanism and tube.

The round baler has an improved feed device for feeding wrapper material from a reel of the material to the baling chamber, wherein the device includes a pair of feed rollers receiving the wrapper therebetween and drivable in directions to pull the wrapper from the reel for presentation to the chamber. A drive is coupled with the feed rollers for driving the rollers at velocities which pull the wrapper from the reel at a speed relatively less than the speed at which the wrapper is pulled from the reel by the bale forming mechanism during wrapping of the bale. The device also includes an overrunning clutch intercoupling the drive and the feed rollers. The clutch drivingly connects the feed rollers to the drive when engaged and drivingly disconnects the rollers from the drive when disengaged. The feed rollers are freely rotatable when the clutch is disengaged for allowing the wrapper to be pulled off the reel by the bale forming mechanism.

Grid members for supporting a bale of hay within the tub of a tilt-tub bale processor are fixed to the floor of the tiltable tub and extend across an opening in the floor in order to control the feed rate of crop materials toward the chopping and disintegrating rotor. The tub is shiftable to any one of a number of slightly tilted orientations so that bottom reaches of the bale within the tub engage only a selected portion of rotor hammers. If the rotor tends to plug, the tub can be tilted away from the rotor and the grid members supporting the bale simultaneously shift lower reaches of the bale away from the rotor hammers so that the latter are able to clear. In preferred embodiments, a knife extends across the floor opening in transverse relation to the supporting grid members to provide a pinch point for crop materials entering the rotor chamber.

The cutting mechanism has a stationary anvil and a movable knife that is swung across the path of travel of the taut, moving wrapper to deflect the wrapper into engagement with the anvil and accomplish severance. A tapered nose on the anvil fits into a slot along the length of the knife as the two components come together whereby the wrapper is stuffed by the nose of the anvil into the slot in a distorted condition, conforming to the shape of the nose and bending over a sharp edge along the slot. As the wrapper becomes gripped within the slot and bent over the cutting edge, it is severed cleanly from the roll and the severed length of the wrapper is delivered to the bale for completion of the wrapping cycle. The knife is in the nature of a tubular member with a slot in its peripheral wall so that the arcuate outer surface of the wall slidingly engages and keeps the wrapper out of contact with the sharp edge until the anvil enters the slot, thereby preventing premature snagging and severance of the wrapper by the sharp edge.

A pair of separate, obliquely disposed, angled-in rakes of the rotating tine bar type are mounted slightly forwardly of the pickup in the marginal areas along side the path of travel of the pickup to engage outlying materials and converge them inwardly into the main portion of the windrow as the baler advances. The tine bars are driven independently of forward motion of the baler by drive mechanism on the baler, and each of the rakes is provided with its own gauge wheel to permit the rake to rise and fall relative to the baler as changes in ground contour are encountered. The rakes slightly overlap the pickup in a lateral sense at their inner end so as to assure discharge of the crop material into the path of travel of the oncoming pickup, and the discharge ends of the rakes are spaced forwardly of the pickup a sufficient distance as to permit the velocity of the rake material to be substantially diminished by the time it is engaged by the pickup.
