A device for conveying and feeding wet material for a cross-flow hot air combine harvester, the device consisting of a hot air pumping part and a material conveying part. The hot air pumping part uses an air suction pump (4) to pump a flow of hot waste air from an engine radiator (1) of the combine harvester by means of an air suction pipeline (3) so as to provide hot air flow for the material conveying and feeding device. The material conveying part consists of a chain harrow-type conveying groove structure (A) and a cross-flow air chamber structure (B), wherein the chain harrow-type conveying groove structure (A) is used for forcibly conveying and feeding a material; and the cross-flow air chamber structure (B) uses hot air to dry the material, blows to assist in feeding the material, and uses a cross-flow air wheel (14) to forcibly feed the material.

A combine comprising a feeder housing, and an auger for receiving harvested crop. The auger includes an auger tube rotatable around an auger axis, and a tined-tube positioned inside the auger tube and rotatable around a tined-tube axis that is offset from the auger axis, the tined-tube including fingers extending from the tined-tube and protruding through the auger tube to convey the harvested crop to the feeder housing.

A dust management system for an agricultural harvester includes a perforated tube extending transversely through a feeder housing of the harvester. The perforated tube has exhaust plenums at opposite ends directing any flow towards the ground over which an agricultural harvester operates. A longitudinal drive shaft mounts axial flow fans within the exhaust plenums and a drive shaft is driven through a pulley system so that rotation of the drive shaft induces flow through the perforated tube and out of the exhaust plenum.

A draper belt tensioning system having a frame having a first tensioner mount, a roller, and a first belt tensioner. The roller is movable along a lateral direction that is perpendicular to a roller rotation axis. The first belt tensioner is connected to the first roller end and selectively connectable to the first tensioner mount. The first belt tensioner includes a first travel stop configured to selectively abut the first tensioner mount with the first tensioner mount between the first travel stop and the first roller end, a first spring, and a first threaded connector configured to move the first roller end closer to and further from the first travel stop upon rotation of the threaded connector. The first travel stop, first spring and first threaded connector are removable from the first tensioner mount without disassembly from each other and without disassembly from the first roller end.

A telescoping rotatable tool includes a first shaft and a second shaft. The first shaft has a first material-engaging element extending from an exterior surface of the first shaft. The second shaft has a second material-engaging element extending from an exterior surface of the second shaft. The second shaft is configured to extend from and retract within an interior space presented by the first shaft. The first shaft includes at least one helical-shaped groove extending along an interior surface of the first shaft. The second shaft includes at least one guide element extending from the exterior surface of the second shaft. The guide element is configured to engage with the groove, such that as the second shaft extends from and retracts within the first shaft, the second shaft is configured to rotate with respect to the first shaft.

A system and method for reversing a rotational direction of an auger of a header. The system includes a fluid line for delivering fluid to a motor that drives the auger. A directional flow control valve is connected to the fluid line and is movable between a first state in which the valve is configured to deliver the fluid to the motor in a first fluid direction to cause the motor to move the auger in a first rotational direction, and a second state in which the valve is configured to deliver the fluid to the motor in a second fluid direction that is different from the first fluid direction to cause the motor to move the auger in a second rotational direction that is opposite to the first rotational direction.

A draper belt assembly for an agricultural harvester that includes a first roller, a second roller, and a draper belt surrounding the first and second rollers. The draper belt includes a front end, a rear end opposite the front end, and an upper surface extending from the front end to the rear end having a width substantially parallel to a longitudinal axis of one of the first and second rollers. The draper belt further includes a plurality of spaced apart lugs each extending in the widthwise direction having an anterior end distal to the rear end and a posterior end proximal to the rear end, wherein the anterior end is spaced from the front end of the draper belt at least about 15 mm.

A feed train assembly for a sugarcane harvester includes a first feed section comprising a plurality of first pairs of upper and lower feed rollers configured to receive a first mat of sugarcane, with such pairs of upper and lower feed rollers comprising a first upstream pair of upper and lower feed rollers. The feed train assembly also includes a second feed section comprising a plurality of second pairs of upper and lower feed rollers configured to receive a second mat of sugarcane, and a combined feed section configured to receive the first and second mats of sugarcane from the first and second feed sections, respectively. A rotational axis of the lower feed roller of the first upstream pair of upper and lower feed rollers is oriented non-parallel relative to a rotational axis of the upper feed roller of the first upstream pair of upper and lower feed rollers.

A self-propelled combine harvester has at least one tilting mechanism for the uniform distribution of a harvested material on an oscillating conveying and cleaning unit, in particular a top sieve. The tilting mechanism has elements for defining a swiveling direction of the conveying and cleaning unit which are arranged between the conveying and cleaning unit and a machine housing. The tilting mechanism has an actuator for continuous adjustment of at least one component part of the elements from an initial position to an adjusting position. The position of the at least one component part decisively defines the swiveling direction. An electric control unit controls the actuator depending on a state of the combine harvester and/or harvested material and the initial position of the at least one component part of the tilting mechanism.

A sugarcane harvester may include a base cutter configured to cut sugarcane, a chopping device in communication with the base cutter to receive the sugarcane cut by the base cutter, the chopping device configured to chop the cut sugarcane into billets, an elevator in communication with the chopping device, the elevator configured to transport the billets out of the sugarcane harvester, the elevator having a discharge end, a forward billet deflector beyond the discharge end of the elevator distant the discharge end, a rearward billet deflector proximate the discharge end and spaced from the forward billet deflector such that the billets fall between the forward billet deflector and the rearward billet deflector and a powered actuator to move the rearward billet deflector to adjust a discharge direction of the billets.
