Sectional type corn kernel cleaning device imitating butterfly wing surface structure

Abstract

The invention discloses a corn kernel cleaning device with a sectional type butterfly wing surface imitating structure. The corn kernel cleaning device comprises a cleaning device driving mechanism, a sectional type butterfly wing surface imitating structure cleaning sieve and a frame assembly, an inner disc type rotating wheel, an outer circle rotating frame, a connecting rod, a driving mechanism shell, a sectional type front-side cleaning sieve and a sectional type rear-side cleaning sieve are installed on an installation frame of the frame assembly. In conclusion, the inner disc type rotating wheel rotates to drive the driving mechanism to enable the sectional type front-side cleaning sieve and the sectional type rear-side cleaning sieve to move, overall stable operation is achieved, and the screening efficiency is high; the screen hole form and the screen hole arrangement of the sectional type front-side and rear-side cleaning screen imitate a butterfly wing surface structure, multi-dimensional screen penetration of removed objects is achieved, the cleaning quality is high, adaptability is high, comb tooth ridges and comb teeth are arranged on the surface of the cleaning screen, guiding, viscosity reduction and accumulation and blockage prevention of the removed objects are achieved, and the strength of a screen body is improved; the rear slide way of the third mounting frame is slightly higher than the front slide way, so that the threshed materials are fully sieved, and the grain loss rate is reduced.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a segmented corn grain cleaning device imitating the surface structure of butterfly wings. Background technique [0002] At present, the sieve body of the corn grain cleaning device mostly adopts a flat integrated sieve, and the sieve body is mostly reciprocating in a plane, and the grains are sieved one-dimensionally on the sieve body. The accumulation and blockage of the sieve holes lead to low screening efficiency and poor operation quality; at the same time, the sieve holes of traditional cleaning devices mostly use round holes. If there are too many holes, the strength of the sieve body will be reduced, and the opening rate of the round hole sieve will be limited. Thus affecting the utilization rate of the sieve body. Contents of the invention [0003] Aiming at the above technical problems, the present invention develops a segmented corn grain cleaning device that imitates ...
