Description

Technical Field

[0001] The present invention belongs to the technical field of corn seed planting, and in particular relates to a corn seed screening device and a screening method for agricultural breeding. Background Art

[0002] Rice is one of the main food crops in my country, with a wide planting area. During the corn planting process, seed screening and processing play an important role in improving corn yield and quality. The corn breeding particle screening device is a device designed specifically for the corn breeding process. It aims to improve seed purity by screening and separating seed particles, providing high-quality seed materials for subsequent sowing, planting, genetic improvement and other work.

[0003] However, existing corn seed pellet screening devices on the market still exhibit some deficiencies in practical applications. In particular, when the corn seed surface is damp, impurities easily adhere to the seed surface, forming a dense layer. This greatly increases the difficulty of separating the impurities from the corn seed, significantly reducing screening efficiency and affecting the overall screening quality of the corn seed pellets. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes a corn seed screening device and screening method for agricultural breeding to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] Furthermore, the third gear is fixedly mounted with a first transmission wheel, the first transmission wheel is connected to a second transmission wheel via a first transmission belt, and the second transmission wheel is rotatably mounted on the operating box.

[0009] Furthermore, the second transmission wheel is fixedly mounted with a first rotating shaft, the first rotating shaft is fixedly mounted with a plurality of cams, and the raised ends of the plurality of cams are in contact with the bottom of the filter screen plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This corn seed screening device achieves precise grading of corn seeds by size through a filter cartridge and two layers of filter screens. Simultaneously, the counter-rotating cleaning brush within the filter cartridge effectively removes larger impurities, preventing clogging and ensuring a continuous and efficient screening process. This design not only improves screening efficiency but also extends the life of the equipment.

[0017] 2. A cam mechanism within the device, driven by a drive wheel and belt, vibrates the filter screen, further improving screening efficiency. This vibration helps distribute the seeds more evenly across the filter screen, accelerating screening. Furthermore, a heating element maintains a suitable temperature within the operating chamber, ensuring the seeds remain dry during the screening process, facilitating their storage and subsequent use.

[0018] 3. The device is equipped with a control panel, allowing operators to monitor and adjust operating parameters such as screening speed and temperature control in real time, achieving intelligent control of the equipment.
