摘要： An improved automatic height adjustment system for use with a header of an agricultural harvester is provided. The system includes apparatus and methods utilizing detection of a light beam at or near the skid plate of a header to adjust the height of the header relative to the ground surface. The apparatus includes an emitter for emitting a beam of light to a receiver. An apertured sensor guide is positioned between the emitter and the receiver. The sensor guide is in communication with a controller. If the body of the sensor guide is detected as blocking passage of light to the receiver then the controller operates an extensible actuator to raise or lower the header relative to the ground surface. The system provides rapid header height adjustment in response to detected changes in elevation of the skid plate as the harvester traverses a crop field.

摘要： A combine including a cutting wheel for harvesting crop, a separating system for threshing the harvested crop to separate grain from residue, at least one of a yield monitor or a loss monitor, a crop cleaning system including a cleaning fan, and a controller coupled to the at least one of the yield monitor or the loss monitor. The controller controls the crop cleaning system, and is configured to determine at least one of a throughput from the yield monitor, or a loss from the loss monitor, compare the determined throughput or loss to a respective throughput threshold or loss threshold, and control a speed of the cleaning fan based on the throughput or loss comparison.

摘要： A preparation section of a combine harvester that is configured to receive a mixture of grain and material other than grain (MOG) from a threshing section of the combine harvester. The preparation section includes a conveyor positioned beneath the threshing section that is configured to transport the grain and MOG in a downstream direction toward a cleaning section, and a deflector positioned at a downstream end of a conveyor that is configured to launch the grain and MOG into the air and cause at least partial separation of the MOG and grain prior to falling onto the cleaning section.

摘要： An agricultural vehicle header having a frame, at least one support arm extending, a cutter assembly attached to the distal ends of the support arms, a draper belt with an upper belt portion located above the support arms, and a parallel linkage connected to each support arm to operatively connect the cutter assembly to the frame. The linkage includes upper and lower links. The upper belt portion extends along a cross-belt direction that is perpendicular to a travel direction of the upper belt portion, and the proximal pivots of the upper and lower links are positioned on a line that is oriented at an angle of 60 to 120 degrees relative to the cross-belt direction when the header is in a freestanding static state.

摘要： A combine grain cleaning system having front and rear rollers, a conveyor belt having an upper surface extending from the front roller to the rear roller, a motor operatively connected to the conveyor belt and configured to drive the upper surface in a belt travel direction from the front roller to the rear roller, and a baffle located adjacent the rear roller. The baffle has a leading edge, a trailing edge located behind the leading edge with respect to the belt travel direction and below the leading edge with respect to a vertical direction, and a baffle surface extending from the leading edge to the trailing edge. One or more sieves are located below the baffle, and a fan is provided to direct an airflow at least partially upwards in the vertical direction adjacent the rear roller. A method for separating grain is also provided.

摘要： An adjustable gathering chain assembly for a header of an agricultural harvester includes a drive unit, a driven unit spaced from and movable with respect to the drive unit and an endless gathering chain extending between the drive unit and the driven unit. An adjustment unit including an idler member in engagement with the gathering chain is operable to move the idler member with respect to the drive unit in order to move the driven unit between first and second positions relative to the drive unit whereby the header may effectively harvest both standing crop and downed or lodged crop depending on harvesting conditions.

摘要： An adjustable gathering chain assembly for a header of an agricultural harvester is disclosed as is a header including such an assembly and methods for adjusting the length of the gathering chain assembly. The assembly includes a drive unit, a driven unit spaced from and movable with respect to the drive unit and an endless gathering chain extending between the drive unit and the driven unit. An adjustment unit including an idler member in engagement with the gathering chain is operable to move the idler member with respect to the drive unit in order to move the driven unit between first and second positions relative to the drive unit whereby the header may effectively harvest both standing crop and downed or lodged crop depending on harvesting conditions.
