[0041] In the process of moving the bearing column 24, the bearing column 24 is rotated on the rack two 342 by the steering piece 32 against the gear two 341, when the gear two 341 rotates in the clockwise direction, the gear two 341 drives the bevel gear piece two 322 to rotate counterclockwise through the bevel gear piece one 321, the bevel gear piece two 322 drives the driving rod two 34 to rotate counterclockwise synchronously, and the lower part of the frame of the steering piece 32 is fixedly connected with the scraping frame 5, so the scraping frame 5 will scrape the metal particles accumulated on the front slope of the cloth bag dust collector 1 synchronously, because the front slope is long, the metal particles will be partially accumulated together in the process of scraping by the scraping frame 5, thereby increasing the weight and being adsorbed on the front slope, and the connecting end of the bearing column 24 and the connecting plate 31 will also move together, the connecting plate 31 will drive the driving rod one 33 to move, the driving rod one 33 drives the gear one 331 to rotate on the rack one 332, the rack one 332 drives the driving rod one 33 to rotate, and the scraping frame 5 connected with the connecting plate 31 will also clean the front slope, and the driving rod one 33 rotates clockwise at this time, the driving rod two 34 rotates counterclockwise, the driving rod one 33 drives the poking rod one 364 to rotate synchronously, the driving rod two 34 drives the poking rod two 362 to rotate synchronously, so the rotation of the poking rod one 364 will drive the driving block two one 363 to be pushed upward, the poking rod two 362 will also drive the driving block two 361 to be pushed upward, with continuous rotation, the poking rod one 364 drives the driving block two one 363 to be pushed downward, the poking rod two 362 drives the driving block two 361 to be pushed downward, so the top-moving bin 36 will be driven to move up and down reciprocatingly, and the sliding grooves on the inner wall of the top-moving bin 36 will enable the driving block two one 363 and the driving block two 361 to slide adaptively in the process of movement, the driving block two one 363 and the driving block two 361 are not in the same sliding groove, so they will not interfere with each other in the process of sliding, when the top-moving bin 36 moves up and down reciprocatingly, the guide column 30 will slide under the limitation of the fixed track plate 242, and the top-moving bin 36 drives the pouring head 351 to slide reciprocatingly through the connecting frame 35, the pouring head 351 contacts the front slope of the cloth bag dust collector 1, which is arc-shaped, so when the pouring head 351 is pushed downward, it will push the accumulated metal particles away, and when the pouring head 351 moves upward, because of the arc shape, the pouring head 351 will not push the metal particles upward, but will make the metal particles fall downward along the arc.

[0042] The setting of the positive slope cleaning assembly 3 can clean the longer positive slope more cleanly, because when the scraping frame 5 cleans the positive slope, if the distance of movement is too long, some metal particles will be accumulated, and the accumulated metal particles will be adsorbed on the positive slope of the bag-type dust collector 1. At this time, the continuously moving unloading head 351 can specially clean the metal particles.

[0043] As a further scheme of the present application, the side slope cleaning assembly 4 comprises a fixed handle 41, a hinged rod 42, a moving handle 43, a rebound head 431, an elastic rotating column 432, a hanging rod 44, and a horizontal connecting handle 441.

The other end of the horizontal connecting handle 441 is fixedly connected to the end of the hanging rod 44.

[0044] During the movement of the fixed track plate 242, the fixed track plate 242 drives the fixed handle 41 to move synchronously. At this time, the hinged rod 42 is pushed to expand outward. The connection between the hinged rod 42 and the moving handle 43 is pushed to the corner of the inner wall of the bag-type dust collector 1. The moving handle 43 slides in the sliding groove in the inner wall of the bag-type dust collector 1, so that the movement of the moving handle 43 is stable. The moving handle 43 is fixedly connected to the rebound head 431. The rebound head 431 drives the fixed handle 41 to move synchronously through the elastic rotating column 432. When the lower part of the hanging rod 44 encounters the bottom of the bag-type dust collector 1, the lower part of the hanging rod 44 is blocked by the bottom of the bag-type dust collector 1 and cannot continue to move as the moving handle 43 continues to move. At this time, the spring sheet in the rebound head 431 acts, so that the elastic rotating column 432 rotates. As the moving handle 43 continues to move, the elastic rotating column 432 continues to rotate, so that the connection between the horizontal connecting handle 441 and the hanging rod 44 continues to clean the wide opening at the bottom of the bag-type dust collector 1.

[0045] The setting of the side slope cleaning assembly 4 can clean the shorter side slope. The structure of the side slope cleaning assembly 4 is simple and easy to maintain, and has an advantage in cleaning the shorter side slope.
