Problems solved by technology

The threshing device mainly uses the principle of impact and friction for threshing. The threshing element and the concave plate sieve exert a line contact or point contact force on the corn ear, and the impact force and rubbing intensity on the grain are large, resulting in a large number of corn grain damage.

Abstract

The invention discloses an axial-flow type rigid-flexible coupling copying corn shelling device. The device comprises an upper shell which is provided with a guide vane, a concave grid which is connected with the upper shell and is enclosed to form a cylindrical hollow structure, a threshing cylinder which is arranged at the center of the cylindrical hollow structure and can axially rotate around the shelling cylinder, wherein an elastic threshing unit is arranged on the inner wall face of the concave grid; and rigid-flexible coupling copying threshing units are uniformly arranged on the shelling cylinder; and the elastic threshing unit and the rigid-flexible coupling copying shelling units are in meshed state relative to the corn ears. According to the axial-flow type rigid-flexible coupling copying corn shelling device, the elastic shelling unit is arranged on the concave grid, and the rigid-flexible coupling copying shelling units are arranged on the shelling cylinder, so that the grain breakage rate can be reduced, and the threshing performance can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and more specifically, the invention relates to an axial-flow rigid-flexible coupling profiling corn threshing device. Background technique [0002] Corn is one of the main food crops in my country. The moisture content of corn grains in most areas is 25% to 40% when harvested. The damage resistance of the grains decreases with the increase of the moisture content. It is easy to cause grain damage when directly threshing. damage. With the acceleration of the mechanization process of corn harvesting, the direct harvesting technology of corn kernels has increasingly become a hot spot and difficulty in the industry. Most of the threshing elements of the existing axial flow threshing device adopt the form of corrugated rods, nail teeth, plate teeth, etc., and are directly rigidly connected to the surface of the threshing drum. The concave screen of the threshing device is composed of g...
