Screening device for rice processing

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a screening device for rice processing. The screening device for rice processing comprises a screening box, wherein a vertical hydraulic telescopic rod is arranged at the middle position of the top end of the inner cavity of the screening box; a horizontal screening barrel is placed inside the inner cavity ofthe screening box; a conveying screw rod is inserted into the screening barrel; a baffle plate is fixedly connected to the other end of the screening barrel; a servo motor is fixedly connected to theouter side of one side wall, near the baffle plate, of the screening box. The screening device for rice processing drives the screening barrel to move up and down through the hydraulic telescopic rod,so that separation of husks and brown rice is facilitated; through the conveying screw rod and the servo motor, conveying and transfer are facilitated and the husks cannot drop down through meshes inthe screening barrel; through a sliding slot, an L-shaped connecting rod and a clamping connector, stabilization of the screening barrel is facilitated; through a rectangular through hole and shock-absorbing blocks, damage of the conveying screw rod to the screening barrel is reduced so as to ensure that the brown rice slides down into a rice discharging column under the action of gravity.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a sieve cleaning device for rice processing. Background technique [0002] Rice is the finished product of paddy after cleaning, husking, rice milling, finishing and other processes. The cleaning process is to use appropriate equipment, through appropriate technological processes and proper operation methods, to remove all kinds of impurities mixed in the rice, so as to improve the quality of the finished rice, and to use magnets to remove iron nails and iron filings in the rice. To ensure production safety. The hulling process is to use a rubber roller huller or emery huller to remove the chaff of the rice and separate the chaff from the brown rice. The cleaning machine is the key equipment in the ridge process. The existing cleaning machine is inconvenient to sieve rice, and it is difficult to separate chaff and brown rice, so the grade of rice cannot be improv...

AI Technical Summary

Problems solved by technology

The existing cleaning machine is inconvenient to sieve rice, and it is not easy to separate chaff and brown rice, so the grade of rice cannot be improved, which seriously affects the sales of rice, and then affects the income of rice. In view of this, we propose a method for rice cleaning. Processing screen cleaning device
