Adjusting mechanism of crop screening device and adjusting method

Abstract

The invention relates to an adjustment mechanism and an adjustment method of a crop screening device, belonging to the field of agricultural machinery. When the crops in the prior art are screened, the crops of the same variety need to use the same size of sieve holes. In the present invention, the sieve hole, the cavity and the limiting groove are all arranged on the sieve plate, the cavity is arranged on the inner wall of the sieve hole, the limiting groove is arranged on the bottom surface of the sieve plate, and the limiting groove communicates with the cavity, and the left limit The cavity and the right limit cavity are installed in the cavity, the left limit seat and the right limit seat pass through the limit groove, the left limit cavity cooperates with the right limit cavity, and one side of the baffle plate is installed on the left limit In the position cavity, the other side of the baffle plate is installed in the right limit cavity, one end of the return spring is connected with the material baffle plate, the other end of the return spring is connected with the cavity, the motor is installed at the bottom of the sieve plate, the screw rod and The motor is connected, and the left limit seat and the right limit seat are all sleeved on the screw mandrel. It can be screened for different varieties of crops, when screening different varieties of crops.

Description

technical field [0001] The invention relates to an adjustment mechanism and an adjustment method of a crop screening device, belonging to the field of agricultural machinery. Background technique [0002] When the crops in the prior art are screened, the crops of the same variety need to be screened with the same size of sieve hole, but when encountering multiple varieties of crops that need to be screened, the sieve can only be replaced, which will increase the production cost input. [0003] In view of this, a crop grading and screening device is disclosed in the patent document with application number 2017109480173. An installation platform and a second installation platform, the first installation platform is provided with several identical working rooms at different heights, each of the working rooms is provided with a first movable plate, and the lower surface of each of the first movable panels is An elastic mechanism is provided, and the side wall of each working c...
