摘要： A crop harvesting machine with a cutter bar on a header frame has a height control system which uses depending sensor fingers arranged in contact with the ground so as to measure a height of the cutter bar above the ground. The sensor fingers are controllably retractable under actuation from an operator in the cab or automatically in response to prescribed conditions being met. The actuator used in retracting the sensor fingers can also be used to adjustably control ground pressure of the sensor fingers in the deployed position of the sensor fingers engaging the ground. The header height is adjusted using laterally spaced apart hydraulic linkages which can be operated at different elevations relative to one another responsive to different height signals relating height of opposing ends of the header frame relative to the ground to also control tilt of the header relative to the harvester frame.

摘要： In a sickle cutting system including a plurality of guard fingers at spaced positions across a cutter bar across which a reciprocating sickle knife passes, each guard finger has a forwardly projecting tip portion in front of a ledger surface and a rearwardly projecting tang portion connected to a rear end of the tip portion and extending therefrom over the ledger surface to a rear edge of the tang portion located over the blade. The lower surface of the tang portion includes a first portion adjacent the tip portion which is generally parallel to the ledger surface and a second portion adjacent the rear edge which is inclined at an angle away from the ledger surface. The width of the tang portion across the rear of the tang portion is equal to or greater than 1.5 inches.

摘要： A clip for a draper of a crop header is arranged to cover a portion of a cleat of a draper where the lower run of the draper comes into contact with a lower support track which confines the lower run to a location clear of the cutter bar and a forwardly extending beam of the crop header frame. The clip forms a channel which features teeth presented at an inside of the channel for biting into the cleat so as to retain the clip thereon with the teeth forming ramped surfaces which can slide along the cleat upon installation of the clip, for example by press fitting the clip downwardly onto the cleat.

摘要： In a header for a crop harvester including two side drapers each a front edge adjacent the cutter bar and a feed draper including a feed draper belt, a front roller behind the cutter bar and parallel thereto and a rear roller with two side edges each adjacent a respective one of the side drapers there is provided a pair of edge seals for engaging a respective side edge of the feed draper belt each comprising a strip of a flexible material extending from a frame member adjacent the respective side edge to a position in engagement with the feed draper at or adjacent the side edge. The strip is distorted by an interference connection with the draper belt so as to follow sagging of the edge of the draper belt by flexing and is biased by a downturned flange of the mounting member into an interference connection with the draper belt.

摘要： A draper header is attached to a harvesting machine by an adapter including a bottom feed draper and an upper feed roller driven by a coupling from an output of the machine rotatable about an axis parallel to the forward direction and a right angle gearbox. The feed roller is mounted at each end allowing independent up and down floating movement of the ends and there is provided a mechanical linkage using two chains and an idler shaft between the output shaft of the gear box an input shaft of the roller with a universal coupling therebetween. The gear box is located at least partly underneath the discharge opening and underneath the feed roller, rearwardly of the rear guide roller of the feed draper, rearwardly of the axis of rotation of the feed roller and underneath a feed pan which is inclined upwardly and rearwardly over the gear box.

摘要： A sickle cutting system is mounted on a header for forward travel over ground having a standing crop thereon and includes a cutter bar with a plurality of knife guards and at least one sickle bar with a drive system for driving the sickle bar through repeated cycles of reciprocating movement from start-up of the system through to a shut-down. The drive system includes an arrangement to halt the sickle bar on shut-down at a predetermined position of the knife blades relative to the knife guards and preferably the position where the blades lie intermediate two knife guards. The system can be halted by either a physical stop member at the required position or by detecting the position of the sickle bar during operation and causing it to halt the required position. The detection can be carried out by counting pulses generated by markers on a rotary member of the drive system.

摘要： A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

摘要： A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

摘要： A crop harvesting header includes a cutter bar arranged across a forward edge of a header frame structure, a draper or auger transport arrangement for transporting the cut crop for further processing, and a reel with a reel drive mechanism for driving rotation of the reel including a variable speed drive motor and a drive transmission having two different drive ratios for high and low speed reel operation. The transmission is mounted in a housing with a readily removable cover part allowing access to a chain and sprocket drive system where the chain can be loosened to allow it to be transferred from one set of cooperating sprockets to another. The reel shaft is movable to release the chain tension and adjusted by a cam and ratchet arrangement.
