Continuous screening device used for crop processing

Abstract

The invention discloses a continuous screening device used for crop processing. The continuous screening device comprises a processing barrel, an annular sliding rail is fixedly connected to the top of the inner wall of the processing barrel, screening boxes are evenly connected to the top of the inner wall of the processing barrel and located in the processing barrel in a surrounding manner, anda bearing shaft penetrates through the positions, on the inner ring of the annular sliding rail, of the screening boxes. A feeding port is formed in the side, close to the bearing shaft, of the top ofeach screening box, and connecting bases are fixedly connected to the portions, located on one sides of the feeding ports, of the top of the surface of the bearing shaft. According to the continuousscreening device, internal crops are subjected to up-down waggling and shaking screening by driving the six screening boxes to waggle and shake up and down, the six screening boxes are subjected to feeding in sequence and conduct continuous screening, fine screening is conducted on the crops in sequence, the crop screening quality is improved, and therefore the crop processing product quality is improved; and the crops are turned over and screened while up-down shaking screening is conducted on the crops, dual screening is achieved, and therefore the continuous crop screening efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of crop processing, in particular to a continuous screening device for crop processing. Background technique [0002] Agricultural product processing is a production activity that uses physical, chemical and biological methods to make agricultural main and by-products into various food or other supplies. It is an important link for agricultural products to enter the consumption field from the production field. Before the agricultural products need to be screened according to the size of the processed products, the size of the crop particles can be processed and sold separately. [0003] At present, the existing screening devices for crop processing cannot perform uniform and continuous screening on a small amount of crops in the process of screening crops, making the screening quality imprecise and reducing the quality of subsequent processed products of crops. Single method screening The screening time is ...
