When the device is used for a long time, a large amount of impurities are accumulated on the surface of the filter screen 3, the impurities are stacked together to block a screen opening, the speed of smoke dust passing through the filter screen 3 is seriously influenced, the dust removal efficiency is reduced, in addition, because the air outlet direction of the air inlet pipe 2 is kept unchanged, and the air inlet pipe 2 is just opposite to the center of the filter screen 3, so that the impurities are accumulated in the middle of the filter screen 3 first, at the moment, the motor 5 can be started to drive the rotating shaft 6 to rotate through the rotating shaft 6, the rotating arm 7 is driven to rotate through the rotating arm 7, the rotating rod I8 is driven to rotate through the meshing transmission of the gear I and the inner toothed ring 4, the rotating plate 10 is driven to rotate through the rotating rod I8, the rotating plate 10 is driven to rotate, the sliding column 11 is driven to push the frame body 12 and the support plate I13 to reciprocate, the support plate I13 is driven to reciprocate the connecting plate 14, and the connecting plate 14 reciprocates to drive the fixing rod 17 to slide along the return groove 16, and drive the dead lever 171 and the scraper 18 to follow the dead lever 17 to move, the dead lever 17 will swing upwards or downwards when the dead lever 171 and the scraper 18 pass the cambered surface portion of the return groove 16, as shown in fig. 1 to 4, when the scraper 18 moves to the middle position of the filter screen 3, keep the lifting state, make it have enough distance with the filter screen 3, prevent the scraper 18 from continuing to push the impurity to the middle of the filter screen 3 instead when moving to the middle position of the filter screen 3, improve the working quality of the scraper 18, when the scraper 18 reaches the middle position of the filter screen 3, the dead lever 17 passes the cambered surface portion of the return groove 16 at this time, make the scraper 18 move downwards, then return again, thus push the impurity in the middle of the filter screen 3 to the edge, and through the rotation arm 7, will drive the rotation lever 8 to rotate around the rotation shaft 6, make the scraper 18 rotate around the rotation shaft 6 while reciprocating, the accumulated impurities in the middle of the filter screen 3 are continuously scraped to the edge, so that the speed of the smoke dust passing through the filter screen 3 is ensured, and the dust removal efficiency is ensured.
When the rotating rod 8 rotates to the position shown in fig. 2 and 3, the rack row 121 on the surface of the frame 12 is meshed with the second gear 19, the second gear 19 and the third rotating rod 20 are driven to rotate by the continuous movement of the rotating rod 8, the second rotating rod 22 is driven to rotate by a certain amplitude through the rotation of the third rotating rod 20 and the action of the belt transmission mechanism 21, the second rotating rod 22 rotates to drive the abutting plate 24 to rotate, as shown in fig. 5 and 6, when the abutting plate 24 rotates clockwise in the direction shown in fig. 5 to contact with the clamping block 28, the second rotating rod 22 rotates continuously to drive the abutting plate 24 to press the clamping block 28 to be separated from the clamping groove 231, the tension spring 27 is stretched by the rotation of the abutting plate 24, the rotating disc 23 is not limited to rotate when the clamping block 28 is separated from the clamping groove 231, and the rotating disc 23 is driven to rotate quickly by the elastic restoring force of the tension spring 27, when the rotating disc 23 rotates to the clamping groove 231 to be matched with the other clamping block 28, the rotating disc is stopped rotating, the rotating disc 23 is rotated fast to drive the filter screen 3 and impurities on the surface of the filter screen to rotate fast, so that the impurities on the surface of the filter screen 3 move towards the edge under the action of centrifugal force, the impurities on the surface of the filter screen 3 are far away from the rotating center under the action of the centrifugal force, namely the middle part of the filter screen 3, when the impurities rotate, because the centrifugal force is related to the radius and the angular velocity, the centrifugal force of the impurities far away from the middle part of the filter screen 3 is larger, so that the centrifugal force can be further increased through the fast rotation of the rotating disc 23, only when the rack bar row 121 rotates to be meshed with the gear wheel II 19, the rotating rod II 22 is driven to rotate by a certain amplitude, when the rotating disc 23 rotates, the scraping plate 18 scrapes the impurities repeatedly, so that the impurities on the edge of the filter screen 3 can be fast screwed into the dust collection box 35 every time when the rotating disc 23 rotates, accelerate the speed of clearance impurity to reduce the time that filter screen 3 is influenced, guarantee the smoke and dust speed of flowing, improve dust collection efficiency, can clear up dust collection box 35 when the maintenance truck work finishes, make things convenient for follow-up use.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
