Description

Technical Field

[0001] The utility model belongs to the technical field of seed screening, and particularly relates to a seed screening and disinfection device. Background Art

[0002] A seed screening device is a special equipment for screening and classifying seeds. Its main purpose is to remove impurities and unqualified seeds in the seeds and classify the seeds according to certain standards. This kind of device is widely used in agricultural production, seed processing and scientific research experiments. It screens, classifies and cleans seeds through physical or mechanical methods. It can effectively remove impurities such as dust, small stones and weed seeds in the seeds, and classify them according to the physical characteristics of the seeds such as size, shape and density to ensure the purity and quality of the seeds.

[0003] For example, the Chinese patent with the publication number CN220554780U discloses a seed classification and screening device, including a screening box. A feeding port is opened at the top of the screening box. Inside the screening box, a screening component for screening rapeseed is arranged at the bottom of the feeding port. The screening component includes a rotating frame. Seeds of different sizes are collected through three-layer pull-out frames. After each layer of collection is completed, they are taken out. After the sealing plate is disassembled, it is resealed on the screening box to collect while screening, improving the screening efficiency of the seeds. Compared with the prior art, through the cooperation of the screening component and the driving component, the rotating frame drives the seeds to rotate reciprocally along the arc plate, accelerating the flow of the seeds and enabling them to quickly pass through the gaps between the partition plates for screening. The driving component changes the distance between the partition plates for screening seeds of different sizes. The screened seeds directly fall into the corresponding collection boxes, improving the seed screening and collection efficiency and avoiding seed blockage of the holes.

[0004] The above patent has the following problems:

[0005] There are some disadvantages when using this patent. For example, after the staff classifies and screens the seeds using the above screening device, in order to ensure that various germs, viruses and insect eggs carried on the surface of the seeds will not affect the survival rate of the seeds, the staff needs to disinfect the screened seeds, increasing the workload of the staff and reducing the work efficiency. In view of this, we propose a seed screening and disinfection device. Summary of the Utility Model
