The water sprayed by the nozzle 11 also acts on the inner wall of the second dust removal tank 2, thereby cleaning the inner wall of the second dust removal tank 2. The dust cleaned by water dust reduction is discharged through the discharge valve 12. This solution cleans the dust on the inner walls of the first dust removal tank 1 and the second dust removal tank 2 by driving the cleaning plate 27 to rotate with the filter barrel 5, sucking the dust inside the first dust removal tank 1 into the second dust removal tank 2 by the blower 4, driving the rotation of the fixed column 29 and the scraper 30 by the rotation of the hollow tube 9, scraping off the dust on the inner wall of the second dust removal tank 2 by the rotation of the scraper 30, spraying water by the nozzle 11 to reduce the dust, and the water sprayed by the nozzle 11 also acts on the inner wall of the second dust removal tank 2, thereby cleaning the inner wall of the second dust removal tank 2. The dust cleaned by water dust reduction is discharged through the discharge valve 12, achieving the cleaning of the dust on the inner walls of the first dust removal tank 1 and the second dust removal tank 2, spraying water by the nozzle 11 to reduce the dust in the second dust removal tank 2, preventing the dust from floating again, and avoiding secondary pollution of the dust.

[0044] Please refer to Figures 1 to 7 As shown in [figure number], the difference based on the combination of the embodiments lies in that several openings 24 are provided on the surface of the filter barrel 5. The top of the first dust removal tank 1 is threadedly connected with a tank cover 8. The inside of the tank cover 8 at the top of the first dust removal tank 1 is rotatably connected with an air inlet pipe 6. An opening is provided on the top surface of the filter barrel 5. The bottom end of the air inlet pipe 6 extends into the filter barrel 5 through the opening, and the air inlet pipe 6 is rotatably connected with the filter barrel 5. A flexible pipe 14 is provided at the top end of the air inlet pipe 6. A collecting pipe 13 is provided at the top end of the flexible pipe 14. An air inlet 15 is provided at one end of the collecting pipe 13. A suction fan is fixedly installed at the end of the air inlet 15.

[0045] Usage steps of the present invention: When the dust-proof device for agricultural equipment is in use and dust removal is carried out on the crusher, since dust and crushed wheat straw may be mixed, it is necessary to filter out the remaining wheat straw and then process the dust. During the process of filtering out the remaining wheat straw, the exhaust fan is turned on. The exhaust fan works to adsorb the dust with the remaining wheat straw into the dust inlet 15. The dust enters the filter cylinder 5 through the collecting pipe 13, the hose 14, and the dust inlet pipe 6. The dust is drawn out from the opening 24 by the blower 4, and the remaining wheat straw is left in the filter cylinder 5. The blower 4 works to suck the dust inside the first dust removal tank 1 into the second dust removal tank 2, and the dust is dusted by spraying water through the nozzle 11 inside the second dust removal tank 2. This solution adsorbs the dust with the remaining wheat straw into the dust inlet 15 through the work of the exhaust fan. The dust enters the filter cylinder 5 through the collecting pipe 13, the hose 14, and the dust inlet pipe 6. The dust is drawn out from the opening 24 by the blower 4, and the remaining wheat straw is left in the filter cylinder 5. The blower 4 works to suck the dust inside the first dust removal tank 1 into the second dust removal tank 2, and the dust is dusted by spraying water through the nozzle 11 inside the second dust removal tank 2. It realizes the filtration of wheat straw, prevents the accumulation of remaining wheat straw from blocking the connecting pipe 3, and ensures the normal operation of the dust removal equipment.

[0046] Please refer to Figures 1 to 7 , the difference based on the combination of the embodiments lies in that a spline 23 is provided at the end of the rotating shaft 21, a groove matching the spline 23 is provided at the bottom of the filter barrel 5, a clamping block 31 is fixedly connected to the inner wall of the filter barrel 5, the top end of the filter barrel 5 is movably connected with an installation cover 32, and a clamping groove 33 engaged with the clamping block 31 is provided on the side surface of the installation cover 32. The above process realizes the cleaning of the remaining wheat straw inside the filter barrel 5.

[0047] The filter barrel 5 is rotationally connected to the rotating shaft 21 through the spline 23, and through the cooperation of the spline 23, it is convenient for the installation of the filter barrel 5.

[0048] The installation cover 32 is mutually clamped with the filter barrel 5 through the clamping block 31, and the clamping block 31 is engaged with the clamping groove 33, which is convenient for taking out the remaining wheat straw in the filter barrel 5.

[0049] Usage steps of the present invention: When using this agricultural equipment dust prevention device, when there is a certain amount of residual wheat straw in the filter cylinder 5, it is necessary to remove the residual wheat straw in the filter barrel 5. The dust removal equipment stops working, remove the lid 8 on the top of the first dust removal tank 1, and draw the filter barrel 5 upward. At this time, the spline 23 is separated from the filter barrel 5, and then the filter barrel 5 is taken out of the first dust removal tank 1. After taking out the filter barrel 5, pull the mounting cover 32 upward, and the clamping block 31 is separated from the clamping groove 33, and then the mounting cover 32 is removed from above the filter barrel 5. Then pour out the residual wheat straw in the filter barrel 5, reinstall the mounting cover 32 on the filter barrel 5, and then install the filter barrel 5 in the first dust removal tank 1 through the spline 23. Insert the dust inlet pipe 6 into the hole above the lid 8, and then screw the lid 8 onto the first dust removal tank 1. The above process realizes the cleaning of the residual wheat straw inside the filter barrel 5.

[0050] Working principle: When cleaning the dust on the inner wall of the dust removal box, first open the discharge valve 12, then start the motor 22. The rotation of the motor 22 drives the rotation of the rotating shaft 21. The rotating shaft 21 drives the rotation of the hollow tube 9 through the belt 34. The rotation of the rotating shaft 21 drives the rotation of the filter cylinder 5. The rotation of the filter cylinder 5 drives the cleaning plate 27 to clean the dust on the inner wall of the first dust removal tank 1. When the motor 22 is started, the blower 4 is also started. The dust cleaned from the inner wall of the first dust removal tank 1 is sucked into the second dust removal tank 2 by the blower 4. The rotation of the hollow tube 9 drives the rotation of the fixed column 29 and the scraper 30. The rotation of the scraper 30 scrapes off the dust on the inner wall of the second dust removal tank 2. When the motor 22 is started, the water pump 17 is also started. The water pump 17 pressurizes the water and enters the second water inlet pipe 7 through the water outlet pipe 18. The second water inlet pipe 7 enters the hollow tube 9, and then the water is sent to the nozzle 11 through the drain pipe 10. The nozzle 11 sprays water to reduce the dust. The water sprayed by the nozzle 11 also acts on the inner wall of the second dust removal tank 2, thereby cleaning the inner wall of the second dust removal tank 2. The dust cleaned by water dust reduction is discharged through the discharge valve 12;

[0051] When dust removing the crusher, since the dust and the crushed wheat straw may be mixed, it is necessary to filter out the residual wheat straw and then process the dust. During the process of filtering out the residual wheat straw, start the exhaust fan. The exhaust fan works to adsorb the dust with residual wheat straw into the dust inlet 15. The dust enters the filter cylinder 5 through the collection pipe 13, the hose 14, and the dust inlet pipe 6. The dust will be drawn out by the blower 4 from the opening 24, and the residual wheat straw is left in the filter cylinder 5. The blower 4 works to suck the dust inside the first dust removal tank 1 into the second dust removal tank 2, and the dust is reduced by spraying water through the nozzle 11 inside the second dust removal tank 2;

[0052] When there is a certain amount of residual wheat straw in the filter barrel 5, it is necessary to take out the residual wheat straw in the filter barrel 5. The dust removal equipment stops working. Remove the lid 8 on the top of the first dust removal tank 1, and pull the filter barrel 5 upward. At this time, the spline 23 is separated from the filter barrel 5, and then the filter barrel 5 is taken out of the first dust removal tank 1. After taking out the filter barrel 5, pull the mounting cover 32 upward, and the clamping block 31 is separated from the clamping groove 33, and then the mounting cover 32 is removed from above the filter barrel 5. Then pour out the residual wheat straw in the filter barrel 5, reinstall the mounting cover 32 onto the filter barrel 5, and then install the filter barrel 5 into the first dust removal tank 1 through the spline 23. Insert the dust inlet pipe 6 into the hole above the lid 8, and then screw the lid 8 onto the first dust removal tank 1. The above process realizes the cleaning of the residual wheat straw inside the filter barrel 5.
