AI Technical Summary

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 rigid-flexible coupling profiling corn threshing device, which comprises: an upper casing, on which guide vanes are arranged; and a concave plate screen, which is connected with the upper casing to form a cylinder type hollow structure, the inner wall of which is provided with elastic threshing units; Shaped threshing unit; wherein, the elastic threshing unit and the rigid-flexible coupling profiling threshing unit are in a meshing shape relative to the ear of corn. The axial-flow rigid-flexible coupling profiling corn threshing device described in the present invention can reduce the breakage rate of grains and improve the threshing rate by arranging elastic threshing units on the concave plate sieve and rigid-flexible coupling profiling threshing units on the threshing drum. Rate.

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...
