[0002] A paddy and brown rice separator is a common grain separation device that separates straws, branches, sands, dusts, etc. in paddy before entering a rice (flour) mill to ensure the cleanliness of rice and flour. Therefore, the exhaust gas of the paddy and brown rice separator contains a large amount of dust, seriously polluting the working environment and affecting the health of workers. After retrieval: A dust collection device for a paddy and brown rice separator with the authorization announcement number of CN204051241U, the dust collection device of the paddy and brown rice separator includes a separation cylinder and a dust accumulation cylinder, the dust accumulation cylinder is detachably arranged below the separation cylinder, and a separable separator is arranged in the separation cylinder. The dust collection device of the paddy and brown rice separator of the utility model uses a separator to separate impurities in the exhaust gas, so that dust and impurities in the exhaust gas directly fall into the dust accumulation cylinder.

[0003] However, the dust collection device of the above-mentioned paddy and brown rice separator still has deficiencies. There is no filtering mechanism at the exhaust pipe. Although most dust can be collected, due to the absence of a filtering mechanism, a small amount of dust will still be discharged from the exhaust pipe, reducing the dust collection and dust removal effect. Therefore, we propose a dust collection device for a paddy and brown rice separator to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned drawbacks and propose a dust collection device for a paddy and brown rice separator.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A dust collection device for a paddy and brown rice separator includes a dust collection cylinder, a separation cylinder and a cover plate used for the dust collection device of the paddy and brown rice separator. The dust collection cylinder and the separation cylinder are fixedly connected. The cover plate is fixedly sleeved on the outer side of the top of the separation cylinder. The top of the cover plate is fixedly communicated with an exhaust pipe. A filtering member is fixedly sleeved on the outer side of the exhaust pipe. One side of the separation cylinder is fixedly communicated with an air pump. The top of the cover plate is fixedly connected with a support plate. The support plate is fixedly sleeved on the outer side of the exhaust pipe. A knocking mechanism for knocking and vibrating the filtering member is arranged between the support plate and the exhaust pipe.

[0007] Preferably, one end of the air pump is fixedly communicated with an air suction pipe.

[0008] Preferably, the filtering member includes a threaded pipe. The threaded pipe is threadedly sleeved on the outer side of the bottom end of the exhaust pipe. The bottom end of the threaded pipe is fixedly communicated with a filter net.

[0009] Preferably, two cavities are formed in the support plate. The knocking mechanism includes two driving motors fixedly connected to the front side of the support plate, rotating shafts rotatably connected to the inner walls of the front and rear sides of the cavities, and a return spring fixedly connected to the inner wall of one side of the cavity. The output shafts of the driving motors are respectively fixedly connected to the front ends of the corresponding rotating shafts. Sector gears are fixedly sleeved on the outer sides of the two rotating shafts. The mutually approaching ends of the two return springs are fixedly connected with moving plates. Tooth plates are fixedly connected to the outer sides of the two moving plates. The two sector gears are respectively meshed with the corresponding tooth plates. Three knocking rods are fixedly connected to the inner sides of the two moving plates. The six knocking rods are respectively movably abutted against both sides of the exhaust pipe.

[0010] Preferably, three through holes are formed in the inner wall of one side of the cavity, and the three knocking rods are respectively slidably sleeved in the corresponding through holes.

[0011] Preferably, rectangular openings are formed on both sides of the support plate, and the two tooth plates are respectively slidably sleeved in the corresponding rectangular openings.

[0012] Preferably, the two moving plates are respectively slidably sleeved in the corresponding cavities.

[0013] Preferably, the cover plate is threadedly sleeved on the outer side of the separation cylinder.

[0014] Preferably, a dust outlet pipe is fixedly communicated with the bottom end of the separation cylinder, and the bottom end of the dust outlet pipe extends into the dust collection cylinder.

[0015] Preferably, a fixing ring is fixedly sleeved on the outer side of the separation cylinder, four screws are threadedly connected to the top of the fixing ring, and the fixing ring is fixedly connected to the top of the dust collection cylinder through the four screws.

[0016] In the present utility model, for the dust collection device of a paddy and rough rice separator, the air outlet of the paddy and rough rice separator is communicated with the suction pipe. By fixing the filter element on the outer side of the bottom end of the exhaust pipe, then tightening the cover plate to block the separation cylinder, and finally through the arrangement of the fixing ring and the screws, the separation cylinder is fixed on the top of the dust collection cylinder. Through the air pump, the dust in the paddy and rough rice separator can be sucked into the suction pipe and finally enter the separation cylinder. The dust falls into the dust outlet pipe and the dust collection cylinder after being separated by the separation cylinder, while the air is intercepted and filtered by the filter screen and then discharged from the exhaust pipe, thereby greatly improving the dust collection and dust removal effect and making it difficult for the dust to escape outside the exhaust pipe.

[0017] In the utility model, the dust collecting device of the grain-rough separator described in the utility model can start two driving motors when it is necessary to clean the filter screen, and the two driving motors drive the two rotating shafts and the fan-shaped gears to rotate, and the two fan-shaped gears drive the two tooth plates, the moving plate and the outer side of the knocking rod to move and squeeze the reset spring. When the tooth plate is not meshed with the fan-shaped gear, under the elastic force of the reset spring, the six knocking rods move inward and knock on the two sides of the exhaust pipe, so that the exhaust pipe can be repeatedly knocked periodically to form vibration. The dust on the filter is then shaken off and collected in the dust collecting tube under vibration, so as to avoid the dust blocking the filter and reducing the dust collection and removal effect. When the device needs to be cleaned and maintained, the cover can be unscrewed, the cover can be removed, and then the threaded tube can be loosened to remove the filter for cleaning and replacement. The fixing ring and the separation tube can be removed from the dust collecting tube by loosening the screws, so as to clean the dust collected in the dust collecting tube and improve the use effect of the device.

[0018] The utility model has a reasonable structural design. By setting a filter at the bottom of the exhaust pipe, the exhausted air can be filtered and intercepted to prevent a small amount of dust from being discharged from the exhaust pipe and reducing the dust collection and removal effect. The exhaust pipe can be repeatedly knocked regularly to make the filter vibrate, which can shake off the dust attached to the filter and prevent the dust from clogging the filter and reducing the dust collection and removal effect. It is also easy to assemble and disassemble, and thus convenient for later cleaning and maintenance of the device. Brief Description of the Figures

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Refer to Figures 1-5 , a dust collection device for a paddy and brown rice separator, including a dust collection cylinder 1, a separation cylinder 3 and a cover plate 5 used for the dust collection device of the paddy and brown rice separator. The dust collection cylinder 1 and the separation cylinder 3 are fixedly connected. The cover plate 5 is fixedly sleeved on the outer side of the top of the separation cylinder 3. The top of the cover plate 5 is fixedly communicated with an exhaust pipe 9. A filter element is fixedly sleeved on the outer side of the exhaust pipe 9. One side of the separation cylinder 3 is fixedly communicated with an air pump 6. The top of the cover plate 5 is fixedly connected with a support plate 8. The support plate 8 is fixedly sleeved on the outer side of the exhaust pipe 9. A knocking mechanism for knocking and vibrating the filter element is arranged between the support plate 8 and the exhaust pipe 9.

[0027] Furthermore, one end of the air pump 6 is fixedly communicated with an exhaust pipe 7. Through the exhaust pipe 7, it is beneficial to be connected with the air outlet of the paddy and brown rice separator, so as to extract the dust in the paddy and brown rice separator for dust collection and dust removal.

[0028] Furthermore, the filter element includes a threaded pipe 20. The threaded pipe 20 is threadedly sleeved on the outer side of the bottom end of the exhaust pipe 9. The bottom end of the threaded pipe 20 is fixedly communicated with a filter screen 21. By arranging the filter element at the bottom end of the exhaust pipe, the discharged air can be filtered and intercepted, avoiding a small amount of dust from being discharged from the exhaust pipe and reducing the dust collection and dust removal effect.

[0029] Further, two cavities 17 are formed in the support plate 8. The knocking mechanism includes two driving motors 11 fixedly connected to the front side of the support plate 8, rotating shafts 12 rotatably connected to the inner walls of the front and rear sides of the cavities 17, and a return spring 14 fixedly connected to the inner wall of one side of the cavity 17. The output shafts of the two driving motors 11 are respectively fixedly connected to the front ends of the corresponding rotating shafts 12. Sector gears 13 are fixedly sleeved on the outer sides of the two rotating shafts 12. The ends of the two return springs 14 close to each other are fixedly connected with a moving plate 15. Tooth plates 10 are fixedly connected to the outer sides of the two moving plates 15. The two sector gears 13 are respectively engaged with the corresponding tooth plates 10. Three knocking rods 16 are fixedly connected to the inner sides of the two moving plates 15. The six knocking rods 16 are respectively movably abutted against both sides of the exhaust pipe 9. When the filter screen 21 needs to be cleaned, the two driving motors 11 are started. The two driving motors 11 drive the two rotating shafts 12 and the sector gears 13 to rotate. The two sector gears 13 drive the two tooth plates 10, the moving plates 15 and the outer sides of the knocking rods 16 to move and compress the return spring 14. When the tooth plates 10 are not engaged with the sector gears 13, at this time, under the elastic force of the return spring 14, the six knocking rods 16 move inward and knock both sides of the exhaust pipe 9, so as to periodically knock the exhaust pipe 9 repeatedly to form vibration. The vibration is transmitted to the exhaust pipe 9, the threaded pipe 20 and the filter screen 21. Then, under the vibration, the dust attached to the filter screen 21 can be shaken off and collected in the dust collection cylinder 1, avoiding the dust clogging the filter screen 21 and reducing the dust collection and removal effect.

[0030] Further, three through holes 18 are formed in the inner wall of one side of the cavity 17. The three knocking rods 16 are respectively slidably sleeved in the corresponding through holes 18. Rectangular openings 22 are formed on both sides of the support plate 8. The two tooth plates 10 are respectively slidably sleeved in the corresponding rectangular openings 22. The two moving plates 15 are respectively slidably sleeved in the corresponding cavities 17, which is beneficial to guiding the tooth plates 10, the moving plates 15 and the knocking rods 16, making their movement more stable and smooth.

[0031] Further, the cover plate 5 is threadedly sleeved on the outer side of the separation cylinder 3, which is beneficial to the disassembly and assembly of the cover plate 5.

[0032] Further, an ash discharge pipe 19 is fixedly communicated with the bottom end of the separation cylinder 3. The bottom end of the ash discharge pipe 19 extends into the dust collection cylinder 1, which is beneficial to the connection between the separation cylinder 3 and the dust collection cylinder 1, and convenient for the dust separated in the separation cylinder 3 to fall into the dust collection cylinder 1 for collection.

[0033] Further, a fixing ring 2 is fixedly sleeved on the outer side of the separation cylinder 3. Four screws 4 are threadedly connected to the top of the fixing ring 2. The fixing ring 2 is fixedly connected to the top of the dust collection cylinder 1 through the four screws 4. Through the arrangement of the screws 4 and the fixing ring 2, it is beneficial to the disassembly between the separation cylinder 3 and the dust collection cylinder 1, and beneficial to the later cleaning of the dust in the dust collection cylinder 1.

[0034] In the present utility model, during use, the air outlet of the paddy and brown rice separator is connected to the suction pipe 7. By fixing the filter element on the outer side of the bottom end of the exhaust pipe 9, and then tightening the cover plate 5 to block the separation cylinder 3. Finally, through the arrangement of the fixing ring 2 and the screw 4, the separation cylinder 3 is fixed on the top of the dust collection cylinder 1. Through the air pump 6, the dust in the paddy and brown rice separator can be sucked into the suction pipe 7 and finally enter the separation cylinder 3. The dust falls into the ash discharge pipe 19 and the dust collection cylinder 1 after being separated by the separation cylinder 3. And the air is discharged from the exhaust pipe 9 after being intercepted and filtered by the filter screen 21, thereby greatly improving the dust collection and dust removal effect, making it difficult for the dust to escape outside the exhaust pipe 9. When it is necessary to clean the filter screen 21, two driving motors 11 can be started. The two driving motors 11 drive the rotation of the two rotating shafts 12 and the sector gears 13. The two sector gears 13 drive the movement of the two toothed plates 10, the moving plate 15 and the outside of the knocking rod 16 and compress the return spring 14. When the toothed plate 10 is not engaged with the sector gear 13, at this time, under the elastic force of the return spring 14, the six knocking rods 16 move inward and knock on both sides of the exhaust pipe 9, thereby periodically knocking on the exhaust pipe 9 repeatedly to make it vibrate. The vibration is transmitted to the exhaust pipe 9, the threaded pipe 20 and the filter screen 21. Thus, under the vibration, the dust attached to the filter screen 21 can be shaken off and collected into the dust collection cylinder 1, avoiding the reduction of the dust collection and dust removal effect due to the blockage of the filter screen 21 by dust. When it is necessary to clean and maintain the device, the cover plate 5 can be unscrewed, and then the cover plate 5 can be disassembled. Then, by loosening the threaded pipe 20, the filter screen 21 can be disassembled for cleaning and replacement. By loosening the screw 4, the fixing ring 2 and the separation cylinder 3 can be disassembled from the dust collection cylinder 1 to facilitate the cleaning of the dust collected in the dust collection cylinder 1 and improve the use effect of the device.
