Description

Technical Field

[0001] The utility model relates to the technical field of agricultural seed screening, in particular to an agricultural seed screening device. Background Technique

[0002] Agricultural seed screening is an important step in the seed planting process. When screening agricultural seeds, it is necessary to select a sieve with a suitable sieve hole according to the shape, size, length and thickness of the seeds for seed grading. Through this step, fine grains, empty grains and impurities can be screened out, and plump seeds can be selected to improve the seed quality. Then, through winnowing, the empty grains, impurities and plump seeds can be separated, so as to further select plump seeds. Finally, the screened seeds are put into water, and diseased grains, insect grains and other impurities are eliminated by using the specific gravity principle. Only through a series of screening processes can healthy seeds that are plump and free of pests and diseases be selected.

[0003] In the current prior art, when screening seeds with pests and diseases through a screening box and using the specific gravity principle, it is necessary for workers to put agricultural seeds into the screening box filled with brine solution. After soaking for a period of time, the healthy seeds will sink to the inner bottom wall of the screening box, while the seeds with pests and diseases will float to the surface of the solution. Then, the workers need to fish out all the floating seeds to remove the inferior seeds with pests and diseases in the agricultural seeds. This process requires the workers to manually fish them out, which increases the labor intensity of the workers. Therefore, an agricultural seed screening device is proposed to solve the above problems. Content of the Utility Model

Then, the workers need to fish out all the floating seeds to remove the inferior seeds with pests and diseases in the agricultural seeds. This process requires the workers to manually fish them out, which increases the labor intensity of the workers.
