Full-automatic grain screening device

Abstract

The invention discloses a full-automatic grain screening device. The full-automatic grain screening device comprises a screening bin, and a feeding hopper is fixedly installed at the top of the screening bin; a second motor is fixedly installed on the right side of the screening bin, a reciprocating plate is movably connected to the right portion of an inner cavity of the screening bin, a conveying belt is fixedly installed on the left side of the reciprocating plate, a moving frame is fixedly connected to the left side wall of the conveying belt, and a spring is fixedly connected to the leftside of the moving frame; a screen is fixedly connected between the lower portion of the inner wall of the left side of the inner cavity of the screening bin and the spring, and the screen is arrangedto be in a folded wave shape; and a discharging opening is fixedly formed in the bottom of the screening bin, a discharging pipe is fixedly installed on the left side of the screening bin, and the discharging pipe is located on the upper side of the screen. The screening device is simple in structure, convenient to use, practical and capable of achieving scattered discharging and enhancing the screening effect.

Description

Technical field: [0001] The invention relates to the field of grain processing, in particular to a fully automatic grain sorting device. Background technique: [0002] The screening device uses a sieve to make the fine-grained material smaller than the sieve hole pass through the sieve surface, while the coarse-grained material larger than the sieve hole stays on the sieve surface, thereby completing the process of separating coarse and fine materials. The separation process can be regarded as composed of two stages: material stratification and fine particle sieving. Material stratification is the condition to complete the separation, fine particles suitable for sieving is the purpose of separation, and the use of screening devices is also indispensable in agricultural processing and production. One step ahead, high-efficiency screening devices can obtain high-quality grain products in the production process of agricultural processing. The existing screening devices have co...

Problems solved by technology

One step ahead, high-efficiency screening devices can obtain high-quality grain products in the production process of agricultural processing. The existing screening devices have complex structures and poor screening effects

In the process of grain collection and processing, professional impurity removers are needed to remove impurities, but it is still unavoidable to be mixed with a small amount of impurities such as wheat straw, rice husk and even dust, which may cause local accumulation and insufficient screening.
