Abstract
A square baler includes a compression chamber, a reciprocating plunger configured to compress bale material in the compression chamber to make a square bale, and a feeding system configured to feed bale material into the compression chamber. The feeding system includes a feeding duct having an input end and an output end, a feeding fork configured to perform a loading stroke to pre-compress bale material in the feeding duct and a feeding stroke to transfer bale material from the feeding duct into the compression chamber. A drive mechanism is provided for driving movement of the feeding fork. The drive mechanism is adjustable to control the length and/or the speed of the loading stroke.
Claims16
A square baler comprising:
- a compression chamber,
- a reciprocating plunger configured to compress bale material in the compression chamber to make a square bale, and
- a feeding system configured to feed bale material into the compression chamber, the feeding system comprising
- a feeding duct having an input end and an output end,
- a feeding fork configured to perform a loading stroke to pre-compress bale material in the feeding duct and a feeding stroke to transfer bale material from the feeding duct into the compression chamber, and
- a drive mechanism for driving movement of the feeding fork,
- wherein the drive mechanism is adjustable to control at least one of a length and a speed of the loading stroke, and
- wherein the drive mechanism includes a feeding fork crank and a steering arm crank, the drive mechanism being arranged such that during the loading stroke, the feeding fork crank and a steering arm crank both rotate, and during the feeding stroke, the feeding fork crank rotates and the steering arm crank does not rotate.
A square baler comprising:
- a compression chamber,
- a reciprocating plunger configured to compress bale material in the compression chamber to make a square bale, and
- a feeding system configured to feed bale material into the compression chamber, the feeding system comprising
- a feeding duct having an input end and an output end,
- a feeding fork configured to perform a loading stroke to pre-compress bale material in the feeding duct and a feeding stroke to transfer bale material from the feeding duct into the compression chamber, and
- a drive mechanism for driving movement of the feeding fork,
- wherein the drive mechanism is adjustable to control at least one of a length and a speed of the loading stroke,
- wherein the drive mechanism includes an asynchronous drive mechanism configured to convert a uniform input speed into a varying output speed, and
- wherein the asynchronous drive mechanism comprises an offset drive mechanism comprising first and second cranks with offset axes of rotation and a connecting arm that connects the first and second cranks and transmits rotational drive therebetween.
A square baler comprising:
- a compression chamber,
- a reciprocating plunger configured to compress bale material in the compression chamber to make a square bale, and
- a feeding system configured to feed bale material into the compression chamber, the feeding system comprising
- a feeding duct having an input end and an output end,
- a feeding fork configured to perform a loading stroke to pre-compress bale material in the feeding duct and a feeding stroke to transfer bale material from the feeding duct into the compression chamber, and
- a drive mechanism for driving movement of the feeding fork,
- wherein the drive mechanism is adjustable to control at least one of a length and a speed of the loading stroke, and
- wherein the drive mechanism comprises a feeding fork crank that is connected directly to a feeding fork and a steering arm crank that is connected to the feeding fork through a first steering arm, a swing arm mounted on a swing arm pivot, and a second steering arm.
