A seed screening machine for agricultural technology promotion

Abstract

The invention discloses a seed screening machine for popularizing agricultural technology. The structure includes a machine base, a spring, a driving box, a screening mechanism, and a feeding hopper. The spring is vertically installed on the upper end of the machine base, and the driving box is embedded and installed inside the machine base. , the screening mechanism is installed horizontally on the upper end of the drive box, and the feeding hopper is installed on the upper end of the screening mechanism. The screening mechanism includes the first screening structure, the discharge pipe, the second screening structure, the third screening structure, and the drive shaft. The discharge pipe is installed on the left end of the outer surface of the first screening structure, the second screening structure is installed horizontally on the lower end of the first screening structure, the upper end of the third screening structure is clipped to the lower end of the second screening structure, and the drive shaft is embedded in the second screening structure. On the inner side of the three screening structures, the present invention sets a soil removal structure above the screen structure, so that it can remove the soil on the outside of the seeds, preventing them from being blocked by the soil and making it difficult to screen, thereby making the screening more accurate and preventing storage The seeds have soil, which is more conducive to the storage and promotion of seeds.

Description

technical field [0001] The invention belongs to the field of modern agricultural technology, and in particular relates to a seed screening machine for agricultural technology promotion. Background technique [0002] Agricultural technology promotion is mainly to promote advanced agricultural scientific and technological achievements and practical technologies, so that farmers can fully grasp agricultural technology and strengthen agricultural development. In agricultural extension, the selection, promotion and use of seeds also play a key role. The quality of seeds Germination and survival rate will be determined, so the seeds need to be screened, that is, the seed screening machine is used to screen and distinguish, but the prior art has the following deficiencies: [0003] Because some seeds are covered with soil, the combination of seeds and soil will increase the overall volume. During the screening, they will not be able to pass through the screen due to the blocking of...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a seed screening machine for agricultural technology promotion, to solve the problem that in the prior art, due to the fact that some seeds are wrapped with soil on the outside, the combination of seeds and soil causes the overall volume to increase. The sieving will not pass through the sieve due to the blockage of the soil, which will affect the sieving, and the original seed volume will not match, and the seeds wrapped in the soil will germinate when the seeds wrapped in the soil are stored in a humid place. The problem that affects the promotion of seeds
