Full-wrap-angle threshing and separating device and threshing method

Abstract

The invention discloses a full-wrap-angle threshing and separating device for a harvester, and belongs to the technical field of agricultural machinery, the full-wrap-angle threshing and separating device comprises a rack, a conical roller part, a threshing roller, a concave grid, a transmission device for driving the concave grid, a tensioning device and two groups of circumferential rolling supporting devices for supporting the concave grid, and the invention further discloses a threshing method. The concave grid is driven through chain transmission, so that the concave grid has the circumferential speed opposite to that of the threshing roller, the threshing roller, the threshing concave plate and the separating concave plate move oppositely, and the threshing wrap angle of grains is increased; therefore, on the premise that the threshing cylinder of the grain harvester is not lengthened and the occupied space of equipment is not enlarged, the grain feeding processing capacity of the grain harvester is improved, the energy consumption is reduced, the threshing rate is improved, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a threshing and separating device and a threshing method for an all-inclusive angle. Background technique [0002] Rice and wheat oil is the main crop rotation in the Yangtze River Basin in my country. Due to the rainy season, lodging, stubble and other reasons, the traditional grain combine harvester usually has problems such as insufficient processing capacity and low net removal rate. For example, by increasing the diameter and length of the drum to increase its crop processing capacity, the overall size of the machine is too large, the structure layout is not compact, the energy consumption for operation increases sharply, and the use of small fields and large machinery is excessive. At the same time, accompanied by problems such as cleaning loss, especially in the case of high moisture content, there is also a decrease in the smoothness of machine operations ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention discloses a full angle threshing separation device and a threshing method, through the chain transmission, the concave plate sieve is driven, so that it has the same The peripheral speed of the threshing cylinder in the opposite direction forms the opposite relative movement between the threshing cylinder and the threshing concave plate and the separation concave plate, which increases the threshing wrap angle of the grain, and not only solves the problem that the equipment occupies a large space in the prior art and the threshing cylinder is blocked, It also improves the grain feeding processing capacity, reduces energy consumption, and improves the cleaning rate
