Second-level soybean screening device for agriculture processing

Abstract

The invention discloses a second-level soybean screening device for agriculture processing. The second-level soybean screening device comprises a bottom plate. A left vertical plate and a right vertical plate are vertically and fixedly arranged on the bottom plate, and an ejector rod is horizontally and fixedly arranged at the upper end of the left vertical plate and the right vertical plate. Theejector rod is sleeved with two sliding sleeves in a sliding manner. The lower ends of connecting rods are fixedly provided with a first lead screw sleeve and a second lead screw sleeve correspondingly. A second lead screw extends rightwards to the right side of the right vertical plate. The right end of the second lead screw is coaxially and fixedly provided with a driving bevel gear. The diameter of sieve holes of a lower sieve plate is smaller than that of sieve holes of an upper sieve plate. The side wall of a screening groove is provided with an upper movable door and a lower movable doorthrough hinges in a connected manner. Through rotation of a first cam and a second cam, the upper sieve plate and the lower sieve plate are driven to reciprocate left and right under elastic acting force of reset springs, and soybean particle screening is promoted. Brush discs rotate while moving left and right in a reciprocating manner, scattering of soybeans on the upper sieve plate is promoted, and the soybean screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a soybean secondary screening device for agricultural processing. Background technique [0002] The scientific name of soybean is soybean. Soybean is an annual herbaceous plant belonging to the family Fabaceae, originating in my country. It has been cultivated in my country since ancient times and has a planting history of 5,000 years. Now it is widely planted all over the country, and it is produced in Northeast China, North China, Shaanxi, Sichuan and the lower reaches of the Yangtze River. It is cultivated more in the Yangtze River Basin and Southwest China, and the quality of soybeans in the Northeast is the best. Soybean is rich in isoflavones, which can cut off the nutritional supply of cancer cells. It contains 8 essential amino acids, multiple vitamins and various trace elements, which can lower blood cholesterol, prevent high blood pressure, coronary hea...

AI Technical Summary

Problems solved by technology

[0003] In the production and processing of soybeans, it is necessary to screen and classify soybean particles according to their particle size to determine the quality of soybean particles. The current soybean screening device does not have a good screening effect, and soybeans cannot be screened quickly. Low, slow sieving speed, unable to achieve good classification of soybeans
