Swinging type automatic agriculture seed screening and drying device

Abstract

The invention discloses a swinging type automatic agriculture seed screening and drying device, and belongs to the technical field of automatic equipment. A screening box is included. A first screening plate and a second screening plate are hinged to the right end of the inner wall of the screening box through hinge blocks. A stirring shaft penetrates through the middle portion of the first screening plate and the middle portion of the second screening plate in a connection manner. The positions, close to the upper ends of the first screening plate and the second screening plate, of the stirring shaft are provided with air spraying discs. The positions, close to the lower ends of the first screening plate and the second screening plate, of the stirring shaft are provided with drive gears.The left ends of the drive gears are engaged with driven gears. Transmission shafts are connected to the middle portions of the left ends of the driven gears. The left ends of the transmission shaftsare provided with cams. The upper ends of the cams make contact with the first screening plate and the second screening plate correspondingly. A hot air box is connected to the middle portion of the upper end of the screening box, and the top end of the stirring shaft penetrates through the screening box and the hot air box to be connected with a stirring motor. According to the swinging type automatic agriculture seed screening and drying device, screening hole blockage is avoided, accordingly, the agriculture seed screening function is achieved, and meanwhile the drying function during agriculture seed screening is achieved.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a swing-type automatic screening and drying device for agricultural seeds. 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. 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. ...

AI Technical Summary

Problems solved by technology

The above are botanical seeds, not seeds for production. Seeds for production include not only the previous botanical seeds, but also organs and artificial seeds that can be used for reproduction. Seeds need to be screened before use. The current screening device, the screening efficiency is poor, and the screening effect is not good, especially when screening, it will block the screen holes, which will seriously affect the quality of later screening

[0003] Chinese patent (publication number: CN108114890A) discloses a screening device for agricultural seeds, including a base and a screening box, a number of iron blocks are arranged on the upper side of the base, springs are arranged on the upper side of the iron block, and the spring The upper end of the electromagnet is connected with an electromagnet, and the upper side of the electromagnet is provided with a supporting platform. Although the device increases the screening effect to a certain extent, in actual operation, the whole electromagnet is used to switch on and off to realize the up and down movement. It is relatively difficult, and at the same time, the stirring blade in the device will interfere with the screen when it rotates, which seriously affects the normal use of the device, so it needs to be improved
