[0003] When selecting rice seeds, the existing seed selection device usually adds prepared salt water into a box or bucket, then pours the seeds into the salt water, and uses the buoyancy of the salt water to make the impurities or unfull and diseased grains in the seeds float on the surface of the salt water, while some full and large seeds sink to the bottom of the water, thereby achieving seed selection;

[0004] However, when the seeds are screened in the above manner, a large amount of seeds will be poured into the salt water and tend to accumulate at the bottom of the box, so that some impurities and incomplete diseased grains are often buried inside and at the bottom of the large amount of seeds, which leads to the screening of impurities and diseased grains being insufficient and incomplete.

[0028] The driving assembly 6 includes two movable chutes 601, two hydraulic cylinders 602 and two movable sliders 603. The two movable chutes 601 are symmetrically opened on the inner wall of the seed selection box 1. The two hydraulic cylinders 602 are respectively fixedly connected to one end of the two movable chutes 601. The two ends of the rotating roller 501 are respectively slidably connected to the side walls of the two movable chutes 601 through the two movable sliders 603, and the two ends of the rotating roller 501 are respectively rotatably connected to the middle parts of the two movable sliders 603.

[0030] The material-snapping assembly 8 includes a support frame 801, a material-snapping plate 802 and two torsion springs 803. The bottom of the support frame 801 is fixedly connected to the side wall of the flipping plate 502, one end of the material-snapping plate 802 is rotatably connected to the middle of the support frame 801, and the two ends of the two torsion springs 803 are respectively fixedly connected to the side wall of the support frame 801 and the side wall of the material-snapping plate 802;

[0031] The bottom of the seed selection box 1 is symmetrically and evenly distributed with a number of support legs 3 fixedly connected, and the side wall of the seed selection box 1 is also equipped with a discharge door 2;

[0032] In this embodiment, first, the seed selection box 1 is supported and fixed by the provided supporting legs 3, and then the prepared brine is injected into the provided brine tank 101, and then the seeds to be screened are poured into the brine tank 101 filled with brine. When the seeds sink and accumulate at the bottom of the brine tank 101, at this time, the two hydraulic cylinders 602 controlled by the same control system are started to provide a force to drive the two movable sliders 603 connected thereto to move back and forth in the two movable slides 601 under force, and the two movable sliders 603 move back and forth to drive the rotating roller 501 to follow the back and forth movement, and the rotating roller 501 moves back and forth and is affected by the resistance of the brine and the seeds to force the rotating roller 501 to rotate during the movement, at this time, the movement and rotation of the rotating roller 501 can drive a plurality of turning plates 502 to move and rotate at the same time to overturn and stir the accumulated seeds, and the provided spring 701 is used to lift The supply force causes the sweeping brush plate 702 to slide out from the inner side of one end of the turning plate 502, and the sweeping brush plate 702 extends out so as to fit with the bottom of the salt water tank 101 during the rotation, so that the seeds attached to the bottom of the salt water tank 101 are swept by the sweeping brush plate 702. At the same time, the turning plate 502 rotates to drive the slapping plate 802 to follow the rotation, and the resistance of the salt water and the impact force when the seeds collide with each other cause the set slapping plate 802 to rotate in the middle part of the set support frame 801, and the set torsion spring 803 provides a reaction force to force the slapping plate 802 to rotate in a rotating manner, so that the seeds can be slapped by the rotation and rotation of the slapping plate 802, so that the seeds are evenly dispersed during the slapping, so that the accumulated seeds can be easily turned over, stirred and evenly scattered, and the impurities and incomplete diseased grains in the seeds can be fully and thoroughly screened out in the salt water.

[0033] Further, the aeration mechanism 4 includes a support plate 401 and an aerator 402, both ends of the support plate 401 are fixedly connected to the top center of the seed selection box 1, the aerator 402 is fixedly connected to the top center of the support plate 401, and the output end of the aerator 402 extends to the inside of the brine tank 101 by penetrating the top center of the support plate 401;

[0034] On the basis of the above embodiment, while the piled and immobile seeds are turned over and stirred, the aerator 402 supported and fixed by the support plate 401 is started to inject "microbubbles" directly into the brine in the brine tank 101 through the air dispersion impeller. The microbubbles slowly rise to the water surface, and the buoyancy of the bubble group is utilized to make the impurities suspended in the water and the incomplete diseased grains float quickly to the liquid surface, thereby achieving the effect of further improving the screening efficiency.

[0035] The implementation principle of a rice seed selection device in an embodiment of the present application is as follows: when in use, first, the prepared brine is injected into the brine tank 101, and then the seeds to be screened are poured into the brine tank 101 filled with brine. When the seeds sink and accumulate at the bottom of the brine tank 101, at this time, two hydraulic cylinders 602 controlled by the same control system are started to provide force to drive the two movable sliders 603 connected thereto to move back and forth in the two movable slides 601 under force, and the two movable sliders 603 move back and forth to drive the rotating roller 501 to follow the back and forth movement, and the rotating roller 501 is driven to rotate. The roller 501 moves back and forth and is affected by the resistance of the salt water and the seeds, so that the rotating roller 501 is forced to rotate during the movement. At this time, the movement and rotation of the rotating roller 501 can drive a plurality of turning plates 502 to move and rotate at the same time to turn over and stir the accumulated seeds, and the spring 701 provides a force to force the sweeping brush plate 702 to slide out from the inner side of one end of the turning plate 502, and the sweeping brush plate 702 extends out so that it fits with the bottom of the salt water tank 101 during the rotation, so that the sweeping brush plate 702 is attached to the bottom of the salt water tank 101. The seeds are swept, and at the same time, the turning plate 502 is driven to rotate with the slapping plate 802, and the resistance of the salt water and the impact force of the seeds when they collide are used to force the slapping plate 802 to rotate in the middle of the support frame 801, and the torsion spring 803 provides a reaction force to force the slapping plate 802 to rotate in a rotary motion. In this way, the seeds can be slapped by the rotation and rotary rotation of the slapping plate 802, so that the seeds are evenly dispersed during the slapping. In this way, it is effective to overturn and stir the accumulated seeds and evenly slap them, and avoid the seeds from accumulating at the bottom of the salt water tank 101. The impurities and diseased grains are not fully and thoroughly screened, so that the impurities and incomplete diseased grains can be screened more fully and thoroughly. Secondly, while the immobile seeds are turned over and stirred, the aerator 402 supported and fixed by the support plate 401 is started to inject "microbubbles" directly into the brine in the brine tank 101 through the air diffusion impeller. The microbubbles slowly rise to the water surface, and the buoyancy of the bubble group is used to make the impurities suspended in the water and the incomplete diseased grains float to the liquid surface quickly, thereby effectively achieving the purpose of further improving the screening efficiency.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
