[0002] Rice is an important crop, and a large amount of rice needs to be sown every year to ensure a sufficient food supply for people. When sowing rice, rice seeds need to be screened to remove the unripe seeds and keep the plump seeds for sowing to improve the survival rate. Existing rice seed screening equipment usually uses water to screen the seeds.

[0003] According to the published patent CN216322563U, this patent makes it relatively easy to retrieve seeds floating on the water surface and take out seeds that have sunk to the bottom. It also recycles the water used for screening, which saves water resources. However, the existing technology cannot screen out the empty shells pressed at the bottom. There may still be empty shells piled up at the bottom during the screening process, resulting in poor screening effect. Utility Model Content

A top plate is lifted and lowered to the upper end face of the screening bucket. The turning assembly is installed on the lower end face of the top plate and extends into the screening basket. The turning assembly includes a motor, a connecting shaft, and a spiral stirring rod. The motor is installed on the upper end face of the top plate. A through hole is provided on the upper end face of the top plate. The connecting shaft is rotatably connected to the through hole and extends out of the through hole at both ends. The upper end face of the connecting shaft is fixedly connected to the output end of the motor. The spiral stirring rod is installed on the lower end face of the connecting shaft.

[0006] Preferably, the upper end face of the support frame is symmetrically mounted with an mounting plate, the lower end face of the top plate is provided with a connecting plate corresponding to the mounting plate, the upper end face of the mounting plate is symmetrically mounted with a telescopic rod, the lower end face of the connecting plate is provided with a mounting hole corresponding to the telescopic rod, and the telescopic rod extends into the mounting hole and is fixedly connected to the mounting hole.

[0007] Preferably, an electric telescopic rod is also installed on the upper end face of the support frame, and an installation block is provided on the outer wall of the connecting plate, with the output end of the electric telescopic rod being fixedly connected to the installation block.

[0008] Preferably, a valve pipe is installed at the lower end of the screening barrel.

[0009] Preferably, the bottom surface of the screening bucket is semi-circular.

[0010] Preferably, an overflow pipe is installed on the outer wall of the screening barrel, and the overflow pipe is connected to the inside of the screening barrel.

[0011] Compared with the prior art, the present invention provides a rice seed screening device, which has the following beneficial effects:

[0012] 1. This rice seed screening equipment, by setting up a screening bucket and a screening basket, can put the seeds into the screening basket and pour in clean water to make the empty shells float, thereby screening the seeds.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-5 This utility model discloses a rice seed screening device, including a screening barrel 1, a screening basket 2, and a turning assembly 3. A support frame 11 is installed on the outer wall of the screening barrel 1. The screening basket 2 is movably installed inside the screening barrel 1. A top plate 4 is lifted and lowered to the upper end face of the screening barrel 1. The turning assembly 3 is installed on the lower end face of the top plate 4 and extends into the screening basket 2. The turning assembly 3 includes a motor 31, a connecting shaft 32, and a spiral stirring rod 33. The motor 31 is installed on the upper end face of the top plate 4. A through hole 41 is provided on the upper end face of the top plate 4. The connecting shaft 32 is rotatably connected to the through hole 41 and both ends extend out of the through hole 41. The upper end face of the connecting shaft 32 is fixedly connected to the output end of the motor 31. The spiral stirring rod 33 is installed on the lower end face of the connecting shaft 32.

[0023] The above design, by setting up a screening bucket 1 and a screening basket 2, allows seeds to be placed into the screening basket 2 and clean water to be poured in, causing the empty shells to float and thus achieving screening. The clean water can pass through the holes of the screening basket 2, while the seeds remain in the screening basket 2, thereby separating the seeds from the water. The stirring component can turn the seeds over, causing the empty shells accumulated at the bottom to be turned upside down, thereby improving the screening effect and cleaning up dust and other impurities attached to the seeds by continuously turning them over.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The upper end face of the support frame 11 is symmetrically equipped with an mounting plate 12, and the lower end face of the top plate 4 is provided with a connecting plate 42 corresponding to the mounting plate 12. The upper end face of the mounting plate 12 is symmetrically equipped with a telescopic rod 13, and the lower end face of the connecting plate 42 is provided with a mounting hole 421 corresponding to the telescopic rod 13. The telescopic rod 13 extends into the mounting hole 421 and is fixedly connected to the mounting hole 421. By setting up the mounting plate 12, the connecting plate 42, the mounting hole 421 and the telescopic rod 13, the top plate 4 can be lifted, thereby facilitating material feeding or unloading, and also facilitating the cleaning of the screening barrel 1.

[0025] Please see Figure 1 , Figure 2The lower end of the screening tank 1 is equipped with a valve pipe 15. By setting the valve pipe 15, sewage can be easily discharged. The bottom surface of the screening tank 1 is semi-circular, which can facilitate the introduction of sewage into the valve pipe 15. An overflow pipe 16 is installed on the outer wall of the screening tank 1. The overflow pipe 16 connects to the inside of the screening tank 1. By setting the overflow pipe 16, the empty shell can be easily discharged through the overflow pipe 16.

[0026] Example 2

The output end of the electric telescopic rod 14 is fixedly connected to the installation block 43. By setting the electric telescopic rod 14, the screening bucket 1 can be opened easily, and the screening basket 2 can be taken out easily, or seeds can be added and taken out.

[0028] Working principle and usage process of this utility model:

[0029] In use, install the switch to start the electric telescopic rod 14, which extends to guide the top plate 4 upward. Then, pour the seeds into the screening basket 2. Press the switch again to retract the electric telescopic rod 14, causing the top plate 4 to descend. At the same time, the spiral stirring rod 33 enters the seeds. Pour clean water into the screening bucket 1 and turn on the motor 31. The motor 31 starts and drives the connecting rod to rotate. The connecting rod drives the spiral stirring rod 33 to agitate the seeds. As clean water is added, the empty shells float on the water surface. When they reach the overflow pipe 16, they are discharged through the overflow pipe 16. After all the empty shells have been screened out, turn off the motor 31 and start the electric telescopic rod 14 again, causing the top plate 4 to drive the spiral stirring rod 33 to rise. At the same time, open the valve pipe 15 to discharge the wastewater. Then, take out the seeds that have been filtered with clean water to complete the operation.
