Hulled rice containing chaff is added to the filter frame. The rice and smaller pieces of chaff fall downwards. When the rice and chaff pass the blower, the blower is activated, blowing the chaff towards the first filter plate. The chaff enters the feeding plate from the first filter plate, while the rice rolls down onto the second filter plate. The chaff moves downwards through the feeding plate, and the blower separates the rice and chaff for chaff removal. Pulling the traction rope moves the slider, compressing the first spring and causing the brush to slide against one side of the first filter plate for automatic cleaning. Releasing the traction rope causes the first spring to return the slider to its original position due to its elasticity, thus moving the brush in the opposite direction for back-and-forth cleaning, reducing filter clogging and preventing clogging from affecting filtration efficiency.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example:

[0023] Reference Figure 1-4 The present invention discloses a pneumatic rice dehulling device, including a dehulling box 1 and a feeding hopper 4 fixedly connected to its upper end. A filter frame 5 is provided inside the feeding hopper 4. A first filter plate 7 is fixedly connected to the inner top wall of the dehulling box 1, and a second filter plate 8 is fixedly connected to one side of the first filter plate 7. A discharge plate 10 is fixedly connected to the connection between the first filter plate 7 and the second filter plate 8, and the other side of the discharge plate 10 is fixed to the inner wall of the dehulling box 1. A fan 9 is installed on one side of the dehulling box 1.

[0024] A brush 16 is slidably disposed at the lower end of the first filter plate 7. A slider 15 is provided on the inner top wall of the chaff removal box 1. The brush 16 is slidably connected to the moving groove 12 through the slider 15. A first spring 14 is fixedly connected between the slider 15 and the moving groove 12. A traction rope 20 is fixedly connected to one side of the slider 15.

[0025] In this embodiment, hulled rice containing bran is added to the filter frame 5. The rice and smaller pieces of bran fall downwards, and the rice and bran pass through the fan 9. Figure 2When the rice is in the middle right position, start the fan 9. The speed and force of the fan 9 need to be adjusted to achieve the desired airflow for rice bran and rice. The fan 9 can blow the rice bran towards the first filter plate 7. The rice bran enters the feeding plate 10 from the first filter plate 7, while the rice rolls down onto the second filter plate 8. The pores of the first filter plate 7 are smaller than those of the second filter plate 8, allowing the rice bran to pass through but the rice not to, and it falls downwards. The rice bran moves downwards through the feeding plate 10, and the fan 9 can separate the rice and rice bran for bran removal. Pull the traction rope 20, and the traction rope 20 drives the slider 15 to move. The first spring 14 is in a compressed state, causing the brush 16 to slide against one side of the first filter plate 7 for automatic cleaning. Release the traction rope 20, and the first spring 14, due to its own elasticity, pushes the slider 15 back to its original position, thereby driving the brush 16 to move in the opposite direction for the purpose of back-and-forth cleaning.

[0026] For further details, please refer to Figure 3 Two limiting rods 13 are fixedly connected between the side walls of the moving groove 12, and the slider 15 is slidably connected to the circumferential side of the two limiting rods 13.

[0027] In this embodiment, the slider 15 moves circumferentially on the two limiting rods 13, which can improve the movement stability of the brush 16 and the slider 15.

[0028] For further details, please refer to Figure 1 The traction rope 20 extends through one side of the hull removal box 1 and is equipped with a winding component. The winding component includes a material distribution shaft 11 installed on one side of the hull removal box 1, and the traction rope 20 is fixedly connected to the circumferential side of the material distribution shaft 11.

[0029] In this embodiment, the dispensing shaft 11 consists of a frame, a drum, and a motor. The frame is fixed to one side of the dehull 1, the drum is rotatably connected to one side of the frame, and the motor is fixed to one side of the frame, with the motor's output end fixed to the drum. When the dispensing shaft 11 is started, the traction rope 20 gradually wraps around the surface of the dispensing shaft 11. The traction rope 20 can pull the slider 15 to move, causing the brush 16 to slide against one side of the first filter plate 7 for automatic cleaning. When the motor rotates in the opposite direction, the traction rope 20 disengages from the surface of the dispensing shaft 11. Due to its elastic recovery, the traction rope 20 pushes the slider 15 back to its original position, thereby driving the brush 16 to move in the opposite direction for back-and-forth cleaning.

[0030] For further details, please refer to Figure 4 An electric stirring rod 6 is rotatably installed on the inner bottom wall of the filter frame 5. Several shaking parts are installed below the filter frame 5. The shaking parts include a mounting plate 18 fixedly connected to one side wall of the feeding hopper 4. A second spring 17 is fixedly connected between the mounting plate 18 and the filter frame 5.

[0031] In this embodiment, after the hulled rice containing bran is added to the bran removal box 1, the electric stirring rod 6 is started. Figure 1 On the upper side, the electric stirring rod 6 rotates, which can break up the rice and rice bran. When the electric stirring rod 6 is working, the electric stirring rod 6 shakes. Due to its own elasticity, the second spring 17 can increase the shaking amplitude of the filter frame 5, thereby performing the screening operation.

[0032] For further details, please refer to Figure 4 The lower end of the filter frame 5 is fixedly connected to a T-shaped rod 19, and the T-shaped rod 19 moves through the lower end of the mounting plate 18. The second spring 17 is sleeved on the circumferential side of the T-shaped rod 19.

[0033] In this embodiment, the T-shaped rod 19 can prevent the second spring 17 from bending when it is compressed or when it elastically recovers.

[0034] For further details, please refer to Figure 2 An electric distributing roller 21 is rotatably installed between the side walls of the feeding hopper 4, and a discharge port 3 is opened on one side wall of the chaff removal box 1. A discharge gate 2 is slidably installed between the side walls of the discharge port 3.

[0035] In this embodiment, the electric distributing roller 21 consists of an electric rotating rod and several distributing plates. The electric rotating rod is rotatably disposed between the side walls of the feeding hopper 4, and the distributing plates are evenly fixed on the surface of the electric rotating rod. When the rice falls, the two distributing plates catch the rice, and when rotating, they tilt the caught rice downwards.

[0036] The implementation principle of the above embodiment is as follows: Hulled rice containing bran is added to the filter frame 5. The rice and smaller pieces of bran fall downwards. When the rice and bran pass through the fan 9, the fan 9 is activated. The speed and force of the fan 9 need to be adjusted to achieve the desired airflow for the rice and bran. The fan 9 blows the bran towards the first filter plate 7. The bran enters the feed plate 10 from the first filter plate 7, while the rice rolls downwards onto the second filter plate 8. The pores of the first filter plate 7 are smaller than those of the second filter plate 8, allowing the bran to pass through. The rice falls downwards, while the rice bran moves downwards via the feeding plate 10. The fan 9 separates the rice from the bran for bran removal. Pulling the traction rope 20 causes the slider 15 to move, compressing the first spring 14 and causing the brush 16 to slide against one side of the first filter plate 7 for automatic cleaning. Releasing the traction rope 20 causes the first spring 14 to return to its original position due to its elasticity, thereby causing the brush 16 to move in the opposite direction for back-and-forth cleaning.
