[0020] This self-cleaning grain throwing device includes a frame 1, a pressure roller 2, a conveyor belt 3, a washing roller 4, and a dewatering assembly. A drive roller 24 is movably mounted on one end of the frame 1 via a mounting plate, bearings, and a short shaft. A driven roller 27 is movably mounted on the other end of the frame 1 via a mounting plate, bearings, and a short shaft. The pressure roller 2 is movably mounted on the frame 1 between the drive roller 24 and the driven roller 27 via a mounting plate, bearings, and a short shaft. The pressure roller 2 is a variable-diameter cylinder. An annular groove 5 is provided in the middle of the pressure roller 2, and bosses 6 are provided at both ends of the annular groove 5.

[0021] The drive roller 24 and the driven roller 27 are fitted with a conveyor belt 3. Multiple round pits 7 are evenly distributed on the outer surface of the conveyor belt 3. During operation, the round pits 7 can increase the friction between the conveyor belt 3 and the grain, thereby enabling the grain to move forward and upward along the conveyor belt 3 to form a high-speed parabolic motion.
[0022] A grain storage box 8 is provided above the drive roller 24. The grain storage box 8 is fixedly installed on the frame 1. A discharge port is provided at the bottom of the grain storage box 8, and the discharge port is correspondingly set with the conveyor belt 3.
[0023] A motor 9 is installed on the frame 1 below the drive roller 24. The motor 9 is connected to the drive roller 24 through the transmission belt 10 and the pulley. When working, the motor 9 can drive the drive roller 24 to rotate. Since a conveyor belt 3 is installed between the drive roller 24 and the driven roller 27, the drive roller 24 rotates synchronously with the driven roller 27 and the conveyor belt 3.
[0024] A cleaning roller 4 is movably mounted on the frame 1 between the driving roller 24 and the driven roller 27 via a mounting plate, bearings, and a short shaft. Brushes 11 are evenly distributed on the circumference of the cleaning roller 4. The brushes 11 of the cleaning roller 4 are in contact with the conveyor belt 3. A water tank 12 is provided on the frame 1 below the cleaning roller 4. A water inlet 13 is provided at one end of the water tank 12, and a water outlet 14 is provided at the bottom of the water tank 12. During operation, the brushes 11 of the cleaning roller 4 can brush the dust adhering to the surface of the conveyor belt 3 and the round pit 7. The water tank 12 is filled with clean water to clean the brushes 11 of the cleaning roller 4. Through the cooperation of the water inlet 13 and the water outlet 14, the water in the water tank 12 can always be kept clean.
[0025] A first water-absorbing roller 15 and a second water-absorbing roller 16 are movably mounted on the frame 1 on one side of the cleaning roller 4. Cotton layers 17 are respectively provided on the circumference of the first water-absorbing roller 15 and the second water-absorbing roller 16. The cotton layers 17 of the first water-absorbing roller 15 and the second water-absorbing roller 16 are respectively in contact with the conveyor belt 3. During operation, the cotton layers 17 can absorb the water remaining on the surface of the conveyor belt 3 and the round pit 7.
[0026] A water-squeezing assembly is provided on the frame 1 corresponding to the first water-absorbing roller 15 and the second water-absorbing roller 16. The water-squeezing assembly includes an assembly plate 18 and a water-squeezing roller 19. The assembly plate 18 is a rectangular plate and is symmetrically arranged on the frame 1. One end of the assembly plate 18 is provided with a slide groove 20. A fixing plate 21 is fixedly installed on the assembly plate 18 outside the slide groove 20 by bolts. The other end of the assembly plate 18 is inclined and is fixedly connected to the frame 1. A positioning plate 22 is slidably installed in the slide groove 20 by a key and a keyway. A pressure spring 2 is installed in the slide groove 20 between the positioning plate 22 and the fixing plate 21. 3. One end of the compression spring 23 is fixedly connected to the positioning plate 22, and the other end of the compression spring 23 is fixedly connected to the fixing plate 21. A squeezing roller 19 is movably installed between the positioning plates 22. The squeezing roller 19 is in contact with the cotton layer 17 of the suction roller. During operation, when the suction roller is driven to rotate by the conveyor belt 3, the squeezing roller 19 rotates simultaneously under the action of friction. Through the cooperation of the squeezing roller 19 and the elastic force of the compression spring 23, the water adsorbed in the cotton layer 17 of the suction roller is squeezed out, so that the cotton layer 17 of the suction roller can adsorb the water remaining on the surface of the conveyor belt 3 and the round pit 7 again.
[0027] A sewage collection tank 25 is provided below the water tank box 12. The water outlet 14 of the water tank box 12 is correspondingly provided with the sewage collection tank 25. The sewage collection tank 25 is correspondingly provided with the cleaning roller 4, the first suction roller 15 and the second suction roller 16. A sewage pipe 26 is provided at one end of the sewage collection tank 25. When working, when the water from the water outlet 14 of the water tank box 12 and the first suction roller 15 and the second suction roller 16 are squeezed out, they fall into the sewage collection tank 25 by their own gravity. The sewage collection tank 25 is used to collect the sewage discharged from the water outlet 14 of the water tank box 12 and the water squeezed out by the first suction roller 15 and the second suction roller 16, and discharges it to the sewer through the sewage pipe 26.
[0028] When using this self-cleaning grain throwing device, the grain is first placed into the grain storage box 8. The grain in the grain storage box 8 falls onto the conveyor belt 3 under its own gravity. Then, the motor 9 is started. The motor 9 drives the active roller 24, the driven roller 27 and the conveyor belt 3 to rotate synchronously through the transmission belt 10. The pressure roller 2 and the conveyor belt 3 work together to force the grain and impurities to move forward and upward along the conveyor belt 3 under inertia, forming a high-speed parabolic motion. Since the material density of stones, grains and chaff in the grain is different, the grain is separated and piled up, which facilitates the collection of grain.
[0029] As the conveyor belt 3 rotates continuously, it drives the cleaning roller 4, the first water-absorbing roller 15, and the second water-absorbing roller 16 to rotate simultaneously. While rotating, the cleaning roller 4 uses its bristles 11 to scrub the dust adhering to the surface of the conveyor belt 3 and the round pit 7. The water tank 12 contains clean water to clean the bristles 11 of the cleaning roller 4. The water inlet 13 and outlet 14 work together to keep the water in the water tank 12 clean. While rotating, the first and second water-absorbing rollers 15 and 16 use their cotton layers 17 to absorb residual water from the surface of the conveyor belt 3 and the round pit 7, allowing the conveyor belt 3 to continue its grain-throwing operation after absorbing residual moisture. When the water-absorbing rollers are rotated by the conveyor belt 3, the squeezing roller 1... Under the action of friction, the rollers rotate simultaneously. Through the cooperation of the squeezing roller 19 and the elastic force of the compression spring 23, the water adsorbed in the cotton layer 17 of the suction roller is squeezed out, so that the cotton layer 17 of the suction roller can again adsorb the water remaining on the surface of the conveyor belt 3 and the round pit 7. When the water is squeezed out from the outlet 14 of the water tank box 12 and the first suction roller 15 and the second suction roller 16, it falls into the sewage collection tank 25 by its own gravity. The sewage collection tank 25 is used to collect the sewage discharged from the outlet 14 of the water tank box 12 and the water squeezed out by the first suction roller 15 and the second suction roller 16, and discharges it into the sewer through the sewage pipe 26, thereby completing the entire self-cleaning operation of the self-cleaning grain throwing equipment.
