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 located at an upper part of the cross-flow air chamber structure (B) and 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. By using excess heat that is generated by the engine of the combine harvester to perform auxiliary blowing and drying during the process of conveying and feeding a wet material, the feeding device may lower the temperature of the engine and reduce the effects of heat radiation and ageing that high temperatures have on surrounding devices, and may lower the water content of a wet agricultural material, thus preventing blockages produced because of moisture.

A draper belt for a head of a harvester that is to extend about a roller having an outer groove encircling the roller and may include a web and an elastomeric belt guide. The web may have a first surface to carry crop material and a second surface to face the roller. The elastomeric belt guide may extend from the second surface and may include downwardly projecting teeth.

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.

Systems and methods for mechanical Cannabis harvesting which utilize a harvester having two counter-rotating rollers, each having a brush thereon, where the brushes serve to strip leaves and buds from the stalk of a standing Cannabis plant introduced to a harvesting space between them. The brushes transport the stripped leaves and buds to a series of conveyors that eventually deposit the leaves and buds in a hopper. The stripped stalk of the Cannabis plant may be left standing in the field to be cut down later, or may be knocked or cut down by the harvester.

An agricultural header for use with an agricultural harvester is configured to cut crop when the agricultural harvester moves in a direction of travel. The agricultural header comprises a first frame, a side draper belt supported by the first frame and positioned to receive cut crop and advance cut crop laterally relative to the direction of travel, a second frame, a center draper belt supported by the second frame and positioned in register with the side draper belt to receive cut crop laterally therefrom and advance cut crop rearwardly toward the agricultural harvester opposite to the direction of travel, and a joint interconnecting the first frame and the second frame and enabling relative fore-aft and lateral translation between the first frame and the second frame.

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.

A header for an agricultural harvester includes: a header frame; a plurality of cutters carried by the header frame and configured to sever crop material; a draper belt carried by the header frame rearwardly of the cutters and configured to travel in a travel direction; at least one crop ramp associated with at least one of the cutters, the at least one crop ramp including a front edge disposed in front of the draper belt and a rear edge that overlaps the draper belt; and a seed saver that is associated with the draper belt and defines a length extending in the travel direction. The seed saver extends above the draper belt and is disposed rearwardly of the rear edge of the at least one crop ramp.

A feeding device for a flexible canvas or draper harvester characterized by upper beam (8) linked to a lower front beam (10) and joined by side covers (11) forming a frame, integral with a lateral stud supports (12) and a central stud supports (13) associated with a central lower beam (9) cut into three sections; the central stud supports (13) are integral with the anchors of the coupling device (15) and with the flexible body supports (14); the central stud supports (13) and lateral stud supports (12) are linked to the conveyor belts with flexible canvases (3, 4, 5 and 6), forming a central body and two laterals with space to accommodate a double row.

A harvest head having a threshing comb, two covers, and two convergent conveyor belts over a third conveyor belt arranged transversely to the first two.
