[0002] With the rapid development of science and technology, agricultural mechanization has become a research hotspot. Although the existing technology has made certain progress in rice seed screening, it still has obvious limitations in using a rotating screen. For example, the holes of the screen are easy to be blocked, especially for smaller seeds such as rice, which are not easy to distinguish, causing the holes to be blocked, increasing the difficulty of cleaning, and seriously affecting the screening efficiency, resulting in an increase in overall operating costs and limiting the further development of rice seed screening technology. Therefore, it is of great significance to develop a selection device for seed production that can efficiently and accurately screen rice seeds while avoiding hole blockage, in order to improve the quality of rice seeds and the efficiency of agricultural production.

Moreover, the first feature can be directly above or obliquely above the second feature, or only indicate that the first feature is higher than the second feature in horizontal height.

[0022] Please refer to Figure 1 The seed selection device 100 for seed production is used for seed screening, and the seed selection device 100 comprises a support 10, a cylindrical screen 20 and a driving device 30. The screen 20 is installed on the support 10 in an inclined manner relative to the horizontal plane, and the driving device 30 is installed on the support 10. The driving device 30 comprises a rotating shaft 31 and a driving motor 32 for driving the rotating shaft 31 to rotate. The outer circumferential surface of the rotating shaft 31 is in abutment and tangential to the outer circumferential surface of the screen 20. The rotating shaft 31 drives the screen 20 to rotate, and the rotating shaft 31 unblocks the blocked holes in the rotating abutment.

[0023] The seed selection device 100 of the present application effectively solves the problem of easy blocking of the holes of the screen 20 in the existing seed screening device by adopting the design of tangential cooperation between the screen 20 and the rotating shaft 31. In the rotating process of the screen 20, the rotating shaft 31 rotates tangentially to the outer circumferential surface of the screen 20, which not only drives the rotating screening of the screen 20, but also unblocks the blocked holes through the rotating abutment. The screening efficiency and accuracy are significantly improved, the operation interruption and cleaning cost caused by the blocking of the screen holes are greatly reduced, and a more efficient and economical seed screening solution is provided. Therefore, the present application has a wide application prospect and significant social and economic value in the field of agricultural seed production, can effectively promote the process of agricultural modernization, and improve the agricultural production efficiency and quality.

[0024] Specifically, please refer to Figure 2The inclination angle of the screen 20 can be adjusted by increasing the lifting mechanism or the cushion, etc. The inner circular surface of the screen 20 is provided with a scraper 21 along the length direction, which is used to stir the rice seeds and prevent the rice seeds from being concentrated on the inner circular surface. In the embodiment of the present application, the scraper 21 has four, which are uniformly spaced and fixed on the inner circular surface. The number of the scraper 21 can be increased or decreased as needed.

[0025] The seeds enter the screen 20 through the upper port and flow out through the lower port and the mesh. The outer circular surface of the upper end of the screen 20 is provided with a retaining ring 22, and the support 10 is provided with a clamping column 11 corresponding to the retaining ring 22 on both sides of the screen 20. The clamping column 11 is provided with a rotating wheel 12, which abuts against the retaining ring 22, so that the screen 20 can be rotatably clamped on the support 10.

[0026] The screen 20 includes a first screen 23 and a second screen 24, the first screen 23 is located at the upper end of the second screen 24, the aperture of the first screen 23 is smaller than that of the second screen 24, and the first screen 23 and the second screen 24 are connected by a transition ring 25. The transition ring 25 separates the two sections with different apertures to prevent the seeds from being mixed together after screening. The size of the aperture of the screen 20 can be determined according to the size of the seeds, which is not limited in the present application. The support 10 is provided with a first receiving hopper 13 and a second receiving hopper 14, the first receiving hopper 13 corresponds to the first screen 23, and the second receiving hopper 14 corresponds to the second screen 24, and the two receiving hoppers are used to prevent the seeds from being mixed again after screening.

[0027] Please refer to Figure 1 The driving device 30 includes a rotating shaft 31 mounted on the cover of the support 10, a driving motor 32 and an auxiliary wheel 33. The rotating shaft 31 and the auxiliary wheel 33 are located in the same plane, and the rotating shaft 31 and the auxiliary wheel 33 are combined to form a mounting table 34 for mounting the screen 20. The lower outer circular surface of the screen 20 is tangentially connected to the rotating shaft 31 and the auxiliary wheel 33. The rotating shaft 31 and the auxiliary wheel 33 are located below the center of gravity of the screen 20. The rotating shaft 31 rotates to drive the screen 20 to rotate.

[0028] The rotating shaft 31 is made of flexible material, such as rubber, silicone, etc. When the rotating shaft 31 abuts against the screen 20, under the action of the gravity of the screen 20, the rotating shaft 31 deforms in the hole of the screen 20 to form a certain protrusion, which extends into the hole to push the stuck seeds, so that the seeds fall off, thereby unblocking the blocked hole.

[0029] In one embodiment, the rotating shaft 31 is provided with anti-skid lines 311, which protrude outward. On the one hand, it can increase the friction to prevent slipping, and on the other hand, it can increase the degree of extrusion deformation, which is beneficial to unblock the blocked hole.

[0030] The seeds enter the upper port of the screen 20, are screened by rotating the inclined screen 20, the small-diameter seeds flow out from the first screen 20, the large-diameter seeds slide along the second screen 24, and the seeds flow out from the second screen 24 and the port, so that three different degrees of seed screening can be realized. However, the large particles of seeds are prone to be blocked in the first screen 23 and the second screen 24. The present application adopts the design that the rotating shaft 31 rotates tangentially with the outer circular surface of the screen 20, so that the problem of easy blocking of the screen 20 holes can be effectively solved, the screening efficiency and accuracy are improved, and the operation interruption and cleaning cost are reduced. The screening effect is optimized by adjusting the inclination angle of the screen 20 and the scraper 21. The design of the two-section screen 20 and the intermediate transition interval avoids seed mixing, and the receiving hopper ensures the classified collection of the screened seeds, thereby providing an efficient and economical solution for agricultural seed production.
