This invention relates to an elephant grass seed threshing device, comprising a frame, a storage device, a feeding device, a threshing device, a dehulling device, and a screening device. The threshing device includes a support, a threshing mechanism, and a threshing conveying mechanism. The threshing mechanism includes threshing rollers arranged vertically and a threshing drive mechanism. Multiple sets of threshing components are arranged on the threshing rollers. The threshing components on the upper and lower threshing rollers are staggered. When the feeding device delivers elephant grass inflorescences into the threshing device, the bottom of the inflorescence passes through the threshing mechanism first and then enters the threshing conveying mechanism. The threshing conveying mechanism includes conveying rollers arranged vertically and a threshing conveying drive mechanism, wherein the linear velocity of the conveying rollers is greater than the linear velocity of the threshing rollers. This elephant grass seed threshing device can automatically thresh elephant grass seeds, achieving a higher degree of automation.

The application discloses a flexible threshing device with adjustable threshing box of a wheat combine harvester, which comprises the threshing box, a transmission shaft one is horizontally arranged at the upper end of the threshing box, and a threshing mechanism is arranged at the middle part of the transmission shaft one. When threshing, the wheat combine harvester throws the wheat into the inlet of the left upper end of the threshing box through the conveying belt, the spiral feeding frame sends the wheat into the space between the two guide plates, when the transmission shaft one rotates, the fixed disc at the middle part drives the cutter to rotate through the lateral rods at the two sides, the cutter slides along the arc-shaped groove at the inner wall of the middle part of the two guide plates, and the guide plates can be expanded, when the two cutters move to the horizontal angle, the two guide plates are reset, with the timed expansion of the guide plates and the cutting of the long wheat in the rotating process of the cutter, the entering wheat cannot be blocked, and the wheat is threshed by the flexible threshing head outside the fixed disc, so that the threshing efficiency is improved, and the blockage during feeding is avoided.

The utility model provides a threshing concave sealing plate convenient to disassemble and assemble and a harvester. A threshing concave sealing plate convenient to disassemble and assemble comprises a first sealing plate welding part, a second sealing plate welding part and a third sealing plate welding part, and one side of the first sealing plate welding part and one side of the third sealing plate welding part are each provided with a first connecting mechanism used for being detachably connected with a reinforcing plate. Second connecting mechanisms used for being connected with the first sealing plate welding part and the third sealing plate welding part are installed on the two sides of the second sealing plate welding part correspondingly. The two sides of the second sealing plate welding part are detachably connected with the other side of the first sealing plate welding part and the other side of the third sealing plate welding part through the second connecting mechanisms respectively.

The invention belongs to the technical field of soybean threshing, and particularly relates to a soybean semi-automatic low-loss single-plant directional threshing device which comprises a support, a threshing box is fixed to the upper side of the support, a lifting mechanism is fixed to the rear side of the threshing box, a swing mechanism is fixed to the lower end of the lifting mechanism, and a clamping mechanism is fixed to the lower end of the swing mechanism. A soybean plant is fixed at the lower end of the clamping mechanism; symmetrical adjusting mechanisms are fixed to the lower end of the inner wall of the threshing box, threshing plates are arranged on the side walls of the two adjusting mechanisms, and the lower ends of the two threshing plates are rotationally connected with the inner wall of the threshing box through shaft pins; according to the soybean threshing device, soybean plants are clamped and fixed through the clamping mechanism, and the soybean plants are driven to swing left and right in a reciprocating mode through the swing mechanism, so that the soybean plants collide with the threshing plate to be threshed, original manual threshing is effectively replaced, the soybean threshing efficiency is greatly improved, manpower is reduced, and the operation comfort of workers is improved.

This utility model provides a threshing device for a harvester and a harvester in general. The threshing device includes a threshing box; a main extrusion roller rotatably disposed within the threshing box; multiple auxiliary extrusion rollers rotatably disposed within the threshing box and distributed circumferentially around the main extrusion roller, with a main threshing gap formed between the side walls of the auxiliary and main extrusion rollers; a driving component for driving the main and auxiliary extrusion rollers to rotate synchronously; and a transmission mechanism for connecting the main and auxiliary extrusion rollers, enabling them to rotate at different circumferential speeds. The auxiliary extrusion rollers can form a stable circumferential speed difference with the main extrusion roller, thereby improving the threshing efficiency of the threshing device, ensuring threshing quality, reducing the load on the main extrusion roller, and lowering the risk of damage to the main extrusion roller. The transmission mechanism allows multiple rollers to operate simultaneously with a single driving component, improving the utilization rate of the power source.
