Abstract

The invention provides a cereal quantitative screening device which comprises a feeding groove, multiple screening cylinders, a first collecting cylinder, a second collecting cylinder and a third collecting cylinder. Multiple feeding holes are formed in the bottom end of the feeding groove, and a quantitative feeding assembly for quantitatively feeding materials into the feeding holes is mounted at the bottom end of the multiple feeding groove. The multiple screening cylinders are vertically arranged below the feeding groove, the top ends of the screening cylinders are connected with the bottom of the feeding groove, and the multiple screening cylinders communicate with the multiple feeding holes correspondingly. A first screen and a second screen which are arranged up and down are mounted in each screening cylinder. The first collecting cylinder is arranged below the feeding groove. The second collecting cylinder is arranged below the first collecting cylinder. The third collecting cylinder is arranged below the second collecting cylinder. According to the cereal quantitative screening device, graded screening of cereal can be achieved by arranging the screening cylinders, the first screens and the second screens, and collection of cereal of different grades can be achieved by arranging the first collecting cylinder, the second collecting cylinder and the third collecting cylinder.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a grain quantitative screening device. Background technique [0002] In the process of grain processing, in order to ensure uniform grain size and grain quality, it is usually necessary to classify and screen grain grains. Screening is to use a perforated sieve surface to divide mixed materials with different grain sizes into various grain size grades. However, the existing grain particle screening device has low screening efficiency. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a grain quantitative screening device. [0004] A kind of quantitative screening device for grains proposed by the present invention comprises a feeding chute, a plurality of screening cylinders, a first collecting cylinder, a second collecting cylinder and a third collecting cylinder; wherein: ...
