[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 - 3 shown, it relates to a rice seed screening device, including a box body 1. The top of the box body 1 is an open design, and a feeding component 2 is provided at the top end inside the box body 1. A motor 3 matching the feeding component 2 is fixed on the outer side wall of the box body 1. Symmetric air inlets 4 and air outlets 5 are provided on the side wall of the box body 1, and both the air inlets 4 and air outlets 5 are located below the feeding component 2. A fan 6 is fixed on the outer side wall of the box body 1 and near the air inlet 4. A discharge port 8 is provided on the side wall of the box body 1 near the air inlet 4. A guide plate 9 is fixed inside the box body 1, and the bottom end of the guide plate 9 extends to the discharge port 8. A water tank 10 is fixed on the outer side wall of the box body 1 and below the discharge port 8. A mesh bag 11 is attached to the inner side wall of the water tank 10. A slag discharge component 13 is installed at the top end of the water tank 10 away from the box body 1.

[0022] The feeding component 2 includes two symmetric inclined plates 21 fixed inside the box body 1. Vertical plates 22 are fixed to the bottom ends of the two inclined plates 21. A roller shaft 23 is provided between the two vertical plates 22. The output shaft of the motor 3 passes through the side wall of the box body 1 and is fixedly connected to one end of the roller shaft 23. A plurality of grooves 24 are equidistantly arranged on the outer side wall of the roller shaft 23.

[0023] After the rice seeds are poured into the inside of the box body 1 from the top of the box body 1, they will accumulate between the two inclined plates 21. At this time, the roller shaft 23 is driven to rotate by the motor 3, and the rice seeds will get stuck in the grooves 24 on the surface of the roller shaft 23. When the grooves 24 rotate from top to bottom, the rice seeds are taken out downward, thereby realizing controllable feeding. By controlling the rotation speed of the motor 3, the feeding speed can be controlled.

[0024] A shielding cover 7 is fixed on the outer side wall of the box body 1 and near the air outlet 5.

[0025] The fan 6 can blow the rice husks and dust in the falling rice seeds towards the air outlet 5 side, and the shielding cover 7 plays a role in preventing the dust and rice husks from flying randomly.

[0026] Both sides of the top end of the water tank 10 are fixedly connected with side baffles 12.

[0027] The side baffles 12 can prevent the rice seeds from sliding down along the guide plate 9 and falling outside the water tank 10.

[0028] The slag discharging assembly 13 includes a side shell 131 fixed to the outer side wall of the water tank 10. A hopper 132 is fixedly connected to the bottom of the side shell 131. A slag discharging pipe 133 is fixedly connected to the bottom of the hopper 132, and a valve is fixed in the middle of the slag discharging pipe 133.

[0029] When the valve on the slag discharging pipe 133 is opened, the rice husks floating on the water surface enter the side shell 131 along with the water, and then are discharged along the hopper 132 and the slag discharging pipe 133.

[0030] A water replenishing pipe 15 penetrates and is fixedly connected to the middle of any one of the side baffles 12. The water tank 10 can be replenished with water through the water replenishing pipe 15, and the water replenishing pipe 15 is connected to a tap water pipe for use.

[0031] A drain pipe 14 is fixedly connected to the bottom end of the side wall of the water tank 10, and a valve is fixedly connected to the middle of the drain pipe 14. By opening the valve, the water in the water tank 10 can be discharged.

[0032] Working principle: Pour the rice seeds to be screened into the box body 1 from the top, and then start the motor 3 and the fan 6. The rice seeds at the top of the box body 1 will slide down along the inclined plate 21, and the rice seeds at the bottom will get stuck in the groove 24 above the roller shaft 23. After the motor 3 drives the roller shaft 23 to rotate, the groove 24 rotates to the lower part, so as to realize the downward discharge of the rice seeds. When the rice seeds fall along the two vertical plates 22, the fan 6 blows the rice husks and dust in the rice seeds out of the air outlet 5, and the rice husks then fall downward along the shielding cover 7. The remaining rice seeds slide onto the water tank 10 along the guide plate 9, and the rice husks float on the water surface, and the qualified rice seeds sink into the mesh bag 11. After the screening is completed, open the valve on the slag discharging pipe 133, and the rice husks enter the side shell 131 along with the water flow, and are discharged along the hopper 132 and the slag discharging pipe 133. Finally, lift the mesh bag 11 out of the water tank 10 to take out the rice seeds. When continuous screening is needed, replenish water into the water tank 10 through the water replenishing pipe 15.

[0033] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made. These embodiments are selected and specifically described in this specification to better explain the principle and practical application of the present invention, so that those skilled in the relevant technical field can understand and utilize the present invention well. The present invention is only limited by the claims and their full scope and equivalents.
