[0031] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth specifically explaining that the reciprocating assembly 4 includes a driving shaft 41, which is rotatably connected to the inner side wall of the processing box 1. The outer surface of the driving shaft 41 is tightly sleeved with two symmetrically distributed cams 42, and the cams 42 are located directly below the screen plate 3. A base plate 43 is fixed to the outer side wall of the processing box 1, and a driving motor 44 is fixed to the top side wall of the base plate 43. One end of the output shaft of the driving motor 44 is coaxially fixed to one end of the driving shaft 41; two mounting plates 45, the two mounting plates 45 are symmetrically distributed and fixed to the inner side wall of the processing box 1, and the top side wall of the mounting plate 45 is fixed with two symmetrically distributed cams 42. A damper 46 of cloth is provided, and one end of the damper 46 is fixed to the side wall of one side of the sieve plate 3. A spring 47 is sleeved on the outer surface of the damper 46. One end of the spring 47 is fixed to the side wall of one side of the mounting plate 45, and the other end of the spring 47 is fixed to the side wall of one side of the sieve plate 3. Through the arrangement of the reciprocating component 4, the sieve plate 3 can be effectively and stably driven to reciprocate up and down, thereby greatly improving the efficiency of the rice impurity removal processing, and can complete the rice impurity removal work in a short time, and can effectively solve the problem of blockage affecting the work during rice impurity removal. It has strong practicality, simple structure and high reliability.

[0032] Further as Figure 4 and Figure 6 As shown, it is worth explaining in detail that the inner side wall of the processing box 1 is rotatably connected to a driven shaft 8, and a plurality of circumferentially distributed stirring rods 9 are fixed to the outer surface of the driven shaft 8. A pulley 10 is arranged between the driven shaft 8 and the driving shaft 41, and a belt 11 is commonly sleeved on the outer surfaces of the two pulleys 10. Through the arrangement of the driven shaft 8 and the stirring rod 9, the material in the processing box 1 can be broken up and stirred, so that the rice can be in a more dispersed state for impurity removal processing, which greatly improves the impurity removal effect of the rice and prevents the impurity removal effect from being affected by the "clumping" phenomenon of the rice.

[0033] This scheme has the following working process: when it is necessary to remove impurities from rice, first pour the material from the feed hopper 16, and drive the driving motor 44 to make the driving shaft 41 rotate synchronously, drive the cam 42 to operate synchronously, and use the extrusion transmission between the cam 42 and the screen plate 3 to make the screen plate 3 move after being compressed, and use the elastic effect of the spring 47 and the damper 46 to make the screen plate 3 always fit the surface of the cam 42, so as to achieve the purpose of the screen plate 3 moving up and down after being stressed, and the screen plate 3 shakes and screens the material, and uses the transmission of the pulley 10 and the belt 11 to The driven shaft 8 rotates synchronously, driving the stirring rod 9 to rotate synchronously, so as to disperse and stir the material in the processing box 1. The vacuum pump 73 drives the pipe a74 to continuously evacuate the connection frame 71, thereby absorbing the air and dust in the processing box 1. The grid plate 14 and the filter plate a72 filter and remove impurities from the gas. The pressurized air is transported to the docking frame 75 through the pipe, and the filter plate b77 filters the gas again, so that the pressurized air is discharged from the air outlet groove 12, thereby accelerating the discharge speed of the material. The material after screening is discharged to the outside through the discharge guide plate 6.

[0034] According to the above working process, it can be known that: through the setting of the reciprocating component 4, the screen plate 3 can be effectively and stably driven to shake back and forth up and down, thereby greatly improving the efficiency of the rice impurity removal processing, and the rice impurity removal work can be completed in a short time. It can also effectively solve the problem of blockage affecting the work during rice impurity removal. It has strong practicality, simple structure and high reliability. Through the setting of the dust reduction component 7, the dust generated by the rice undergoing impurity removal processing can be effectively adsorbed, thereby effectively preventing the dust from seriously affecting the surrounding environment when the rice is shaken for impurity removal. It has better protection for the staff, prevents the excessive inhalation of dust from affecting the health, and effectively improves the overall working environment quality during rice impurity removal.

[0035] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, it is worth specifically explaining that the dust reduction component 7 includes two connecting frames 71, the two connecting frames 71 are fixed to the side wall of one side of the processing box 1, the connecting frame 71 is connected to the inside of the processing box 1, and a filter plate a72 is slidably penetrated through the inner side wall of the connecting frame 71. An air pump 73 is fixed to the outer side wall of the processing box 1, and a connected pipe a74 is fixed between the input end of the air pump 73 and the two connecting frames 71. A docking frame 75 connected to the inside is fixed to the outer side wall of the processing box 1, and a filter plate a72 is fixed between the output end of the air pump 73 and the docking frame 75. The connected pipe b76; the filter plate b77, the filter plate b77 is fixed to the inner side wall of the docking frame 75, and the filter plate b77 is located directly below the pipe b76. Through the setting of the dust reduction component 7, the dust generated by the rice undergoing impurity removal processing can be effectively adsorbed, thereby effectively preventing the situation in which the surrounding environment is seriously affected by dust when the rice is shaken for impurity removal. It has better protection for the staff, preventing the excessive inhalation of dust from affecting the health, and effectively improving the overall working environment quality during the rice impurity removal work.

[0036] Further as Figure 3 and Figure 7 As shown, it is worth explaining in detail that two air outlet grooves 12 are provided on the side wall of one side of the discharge guide plate 6, and a baffle 13 is fixed inside the air outlet groove 12. The baffle 13 and the discharge guide plate 6 are arranged in an inclined distribution, and the air outlet groove 12 is located on one side of the docking frame 75. Through the arrangement of the air outlet groove 12 and the baffle 13, the pressurized air is discharged to the discharge guide plate 6 by the air outlet groove 12, which can greatly improve the material discharge speed after impurity removal and avoid the situation where the material is not discharged smoothly due to retention. With the arrangement of the baffle 13, the material can be effectively prevented from falling into the air outlet groove 12.

[0037] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the vertical cross-section of the stirring rod 9 is set in a T shape, and the cross-section of the screen plate 3 is set in an arc shape. The shape setting of the stirring rod 9 effectively improves the breaking and stirring effect of the material, so that the breaking and stirring effect of the material can be significantly improved.

[0038] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth explaining in detail that two symmetrically distributed grid plates 14 are fixed to the inner side wall of the processing box 1, and the grid plates 14 are located on one side of the connecting frame 71. A support frame 15 is fixed to the bottom side wall of the processing box 1, and a feed hopper 16 is fixed to the top side wall of the feed pipe 2. The aperture value of the grid plate 14 is greater than the aperture value of the filter plate a72. The grid plate 14 is set on one side of the filter plate a72, and the grid plate 14 blocks impurities with larger particle sizes floating in the air, and the filter plate a72 filters the gas again, effectively preventing the impurities from entering the vacuum pump 73 and causing its structural damage.

[0039] In summary: through the setting of the air outlet groove 12 and the baffle 13, the pressurized air is discharged to the discharge guide plate 6 by the air outlet groove 12, which can greatly improve the material discharge speed after the impurities are removed, and can avoid the situation where the material is not discharged smoothly due to the retention of materials. With the setting of the baffle 13, the material can be effectively prevented from falling into the air outlet groove 12, and the shape setting of the stirring rod 9 can effectively improve the material breaking and stirring effect, so that the material breaking effect can be significantly improved, and through the setting of the driven shaft 8 and the stirring rod 9, the material in the processing box 1 can be broken and stirred, so that the rice can be in a more dispersed state for impurity removal processing, which greatly improves the impurity removal effect of the rice and prevents the impurity removal effect from being affected by the "clumping" phenomenon of rice.

[0040] Both the driving motor 44 and the vacuum pump 73 can be purchased from the market. Both the driving motor 44 and the vacuum pump 73 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
