Description

Technical Field

[0001] This application relates to the field of seed sorting machines, and more specifically, to a gravity-based corn seed sorting machine. Background Technology

[0002] A specific gravity-based seed sorting machine utilizes the difference in specific gravity between seeds of varying quality. Shriveled seeds have a lower specific gravity. Inside the sorting machine, the sieve bed, through vibration and airflow, separates high-quality corn seeds from shriveled seeds on the sieve surface. The heavier seeds are at the bottom, and the lighter shriveled seeds are at the top. As the sieve bed vibrates, the heavier seeds are pushed towards the discharge end, while the lighter shriveled seeds move towards the lower discharge direction, thus achieving the sorting purpose. A specific gravity-based corn seed sorting machine is disclosed in publication number CN217094389U. The gravity-type corn seed sorting machine uses a gravity-based sorting method to classify and separate seeds of different qualities. During the sorting process, a fan assists in blowing out impurities from the seeds. However, the inventor believes that the aforementioned related technologies still have the following drawbacks: the sorting machines in the comparative literature are difficult to feed seeds, require a lot of labor, and generate a large amount of dust during seed sorting, causing dust pollution to the surrounding environment. Corn silks and leaves mixed in with the corn seeds cannot be effectively screened out, reducing their practicality. Therefore, we propose a gravity-type corn seed sorting machine. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a gravity-type corn seed sorting machine, which solves the technical problems in the prior art, such as difficulty in feeding seeds, high labor costs, and the generation of a large amount of dust during seed sorting, causing dust pollution in the surrounding environment. Furthermore, the machine cannot effectively remove corn silks and leaves mixed in with the seeds, reducing its practicality. This new sorting machine is lightweight and suitable for home use, easily movable by vehicle. When sorting corn seeds, the seeds can be easily placed in the first hopper and then mechanically fed to the second hopper using a screw conveyor, reducing manual labor. Seeds mixed with corn silks and impurities are evenly scattered by the vibrating rotating plate. A circulating fan removes dust from the top of the cover through a suction pipe, and a blower can blow the silks out of the cover. Then, with the cooperation of a vibrating screen and a bellows, the heavy corn seeds and shriveled impurities are separated and discharged in layers, achieving a pollution-free and impurity-free sorting effect.
