Description

Driving mechanism of corn kernel cleaning sieve

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a driving mechanism of a corn kernel sorting screen.

Background

Due to the defects and problems in the aspect of structural design, the conventional corn kernel sorting screen can only realize the reciprocating parallel direction swinging motion after the screen body is obliquely arranged. Therefore, when the corn cleaning mechanism is used in operation, corn grains on the surface of the screen body cannot be rapidly and uniformly distributed on the effective area of the surface of the screen body, the surface area of the screen body cannot be fully and effectively utilized, the operation efficiency is low, and the corn grain cleaning effect and quality are poor.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and researches and designs a corn kernel cleaning sieve driving mechanism with a new structure so as to achieve the purposes of simple and compact structure, stable operation, low noise, high cleaning operation efficiency and good quality.

The invention aims to realize that a driving mechanism of a corn kernel cleaning sieve comprises an upper sieve and a lower sieve, wherein a supporting beam is fixedly arranged on the side part of the bottom of a sieve box frame, a gear box shell and an upright slideway are respectively and fixedly arranged on the supporting beam, the upright slideway is positioned at the central part of the gear box shell, a driving bevel gear and four driven bevel gears are arranged in the gear box shell, the driving bevel gear is meshed with the four driven bevel gears, the four driven bevel gears are respectively and fixedly arranged with four gear shafts, the four gear shafts are respectively and fixedly connected with four connecting rods, the four driven rods are respectively and fixedly arranged on the four connecting rods, pushing blocks which respectively rotate in the circumferential direction and move in the axial direction are sleeved on the four driven rods, four sieve surface supporting rods are respectively and fixedly arranged on the four pushing blocks, two sieve surface fixing plates are sequentially and fixedly arranged on the four sieve surface supporting rods from top to, the two screen surface fixing plates are radially positioned, can rotate in the circumferential direction and can move axially, and are sleeved on the upright column slide way, and the upper screen and the lower screen are respectively arranged on the upper screen surface fixing plate and the lower screen surface fixing plate.

The invention adopts the technical scheme of connecting and combining the conical gear drive and the rod piece, realizes the compound motion of synchronous up-and-down direction reciprocating linear motion and circumferential reciprocating circumferential swing of the upper sieve and the lower sieve, and has the characteristics of novel, reasonable, simple and compact structure, stable operation, low noise, reliable use, high cleaning efficiency and good quality.
