Seed screening preprocessing device

Abstract

The invention discloses a seed screening preprocessing device which comprises a device body. An upper guiding cylinder and a lower guiding cylinder are arranged at the upper portion and the lower portion of the inner side of the device body. A dust removal net cylinder is installed between the upper guiding cylinder and the lower guiding cylinder, an inner cavity of the dust removal net cylinder is a dust removal cavity, a conveying pipe is installed in the middle of the top of the device body, a driving mechanism for driving the conveying pipe to rotate is further arranged at the top of the device body, a raw material box is installed at the upper end of the vertical portion of the conveying pipe, an air conveying pipe is installed in the middle of the bottom of the device body, the upperend of the air conveying pipe is fixedly connected with the conveying pipe, a plurality of exhaust heads are installed on the air conveying pipe inside the dust removal cavity, the lower end of the air conveying pipe is connected with the air inlet pipe through a rotating joint, and the other end of the air inlet pipe is connected with an air pump. The structure is reasonable in design, drying and dust removal preprocessing processing can be performed before seed screening, and the follow-up seed screening processing quality and effect are improved.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a seed screening pretreatment device. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is the basic industry that provides support for the construction and development of the national economy. [0003] Seeds, the characteristic propagules of gymnosperms and angiosperms, which are formed by pollination and fertilization of ovules. Seeds are generally composed of three parts: seed coat, embryo and endosperm. Some mature seeds of plants only have two parts: seed coat and embryo. Seed formation enables young sporophy...

AI Technical Summary

Problems solved by technology

During the processing of seeds (wheat, soybean, corn and sesame, etc.), screening operations are required. In order to make the quality of seed screening and processing better, a seed screening pretreatment that can be used for drying and dust removal pretreatment before seed screening is proposed. device to overcome the deficiencies in current practical applications and meet the needs of seed production and processing
