Description

Technical Field

[0001] The present application relates to the technical field of screeners, and more particularly to an agricultural seed screener. Background Art

[0002] Seeds are the foundation of agricultural development, and high-quality seeds are crucial to the final harvest. Damaged seeds can cause a loss of nutrients, affecting germination and growth. Furthermore, seeds can contain fine sand, as well as unfilled or shriveled seeds. Failure to pre-screen these impurities can significantly reduce germination rates.

[0003] The document with the prior art publication number CN220425922U provides a seed screening device, which discharges the seeds in the discharge hopper in batches through the discharge component, which can make the seed screening more uniform and thorough, and will not cause accumulation and insufficient screening, thereby improving the screening effect and screening efficiency. The two screen plates are driven to move back and forth by the screening component to screen the seeds, which can improve the seed screening effect; the half gear is driven by the driving motor to reciprocate and mesh with the two rack plates respectively, which can drive the two screen plates to move back and forth to screen the seeds, thereby improving the seed screening effect, and at the same time, it can also avoid the sieve plates from being blocked during the screening process, thereby improving the screening efficiency. While the driving motor rotates, it can also drive the rotating column and the discharge trough to feed the seeds in batches, so that the seeds are screened more evenly, further improving the screening effect.

[0004] Although this device has many beneficial effects, the following problems still exist: when the staff opens the box door, the relatively round bean seeds can easily roll off the sieve plate and onto the ground, requiring the staff to clean the seeds that have rolled onto the ground, which easily increases the staff's workload. In view of this, we propose an agricultural seed screener. Utility Model Content

[0005] The embodiment of the present application provides an agricultural seed screener to solve the technical problem in the prior art that when the staff opens the box door, the relatively round bean seeds are very likely to roll off the sieve plate to the ground, requiring the staff to clean the seeds that have rolled on the ground, which easily increases the workload of the staff.
