Description

Technical Field

[0001] The present application relates to the technical field of seed screening, and more specifically, to a tool for selecting and grading crop seeds. Background Art

[0002] Seed grading mostly uses manual winnowing, picking, sieving and other methods to complete seed selection. The manual selection method has problems such as low work efficiency, high labor intensity, and poor working environment, which brings a lot of trouble to seed selection. Although some manufacturers have produced some simple seed processing equipment and application technologies, they all have problems such as uneven seed size, excessive seed damage and loss, and mixed waste residues and debris in the seeds are difficult to remove, and cannot provide efficient and high-quality seeds to meet the needs of modern seed production.

[0003] A document with prior art announcement number CN220111638U provides a tool for selecting and grading crop seeds. In the related technology of the device, light dead seeds can be vibrated to the upper layer of intact seeds through continuous vibration, which is convenient for identification. In addition, users can increase or decrease several levels of screening devices through a joystick as needed to facilitate grading, thereby avoiding problems such as uneven seed size, seed damage and excessive loss.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the sieve plate structure is used for graded screening, the seeds are concentrated and accumulated at the bottom of the sieve frame, resulting in a slow screening speed and the need for repeated stirring through a stirring head.

[0005] In view of this, we propose a crop seed selection and grading tool. Utility Model Content

[0048] The crop seed selection and grading tool can guide and discharge the seeds screened by the screening cylinder 31 by utilizing the discharge plate 32 and the extension plate 33 .
