The dust scraping assembly includes an annular scraping knife, a plurality of knife rods and a plurality of hydraulic cylinders. The scraping knife is closely attached and slidably arranged on the outside of the filter cartridge. The knife rods are evenly distributed on the outside of the scraping knife and are horizontally arranged. One end of the knife rod is fixedly connected to the scraping knife, and the other end is connected to the telescopic end of the hydraulic cylinder. The hydraulic cylinders are arranged corresponding to the knife rods and are vertically and fixedly connected to the inner wall of the body. The air inlet channel includes a round hole arranged on the right side of the body, a circular spring tube fixedly connected to the round hole, and a flange fixedly connected to the other end of the circular spring tube.
[0005] Further, a dust removal filter bag is sleeved on the outside of the filter cartridge.
[0006] Further, the number of the knife rods and the hydraulic cylinders is four. The knife rods are evenly distributed on the outside of the scraping knife, and the hydraulic cylinders are arranged corresponding to the knife rods and are evenly distributed on the inner wall of the body.
[0007] Further, brackets are evenly distributed on the bottom surface of the body to support the pulse dust collector.
[0008] Further, a pre-filter screen is arranged inside the circular spring tube to filter out large particles of dust or impurities.
[0009] Further, the hydraulic cylinders are electrically connected to a driver, and the driver controls the hydraulic cylinders to expand and contract simultaneously to control the horizontal up and down movement of the scraping knife.
[0010] Furthermore, a support wire is arranged inside the circular bellows to support the shape of the circular bellows.
[0011] Furthermore, a number of dust removal holes are arranged on the outer side of the dust collection box. A cover plate is arranged on the dust removal holes. The cover plate is sealed by bolts and detachably connected to the dust removal holes.

In addition, the filter cartridges or fans not defined in the present utility model all adopt conventional technical means in the art.
[0013] The working principle of the present utility model is that the device sucks in the air containing dust through the air inlet channel, first removes large particles of dust or impurities through the pre-filter screen, passes from the outside of the filter cartridge through the dust removal filter bag to the center of the filter cartridge to achieve the dust removal effect, and the dust-removed air leaves the pulse dust collector through the variable-diameter pipeline via the fan; after long-term use, dust accumulates and caking appears on the outer wall of the filter cartridge. The driver controls the hydraulic cylinders to expand and contract simultaneously, controls the scraping knife to move horizontally up and down, scrapes the dust on the outside of the filter cartridge, reduces the resistance of the dust removal system, and achieves the initial dust removal effect of the device.
