The first mounting groove 23 is provided with a flat gear 25, and the second mounting groove 24 is provided with a bevel gear 26. The shaking cleaning cutter head 2 is rotated by the transmission belt of the pneumatic motor 1, so that the flat gear 25 and the bevel gear 26 slide outwardly under the centrifugal force and fully contact with the inner wall of the pipeline. The centrifugal force generated by the rapid rotation drives the gears in the shaking cleaning cutter head 2 to dry-clean the moderate and severe hard powder-like and hard solid-like scaling on the inner wall of the oil pipe, with fast speed and good descaling effect.

[0025] Furthermore, sliding holes are equidistantly provided at the top of the positioning piece 22, the spur gear 25 and the bevel gear 26 are coaxially connected, and the rotating shafts of the spur gear 25 and the bevel gear 26 are slidably connected to the sliding hole at the top of the positioning piece 22, and the rotating shaft size of the spur gear 25 and the bevel gear 26 is smaller than the sliding hole at the top of the positioning piece 22.

[0026] Furthermore, the size of the middle portion of the cutter head body 21 is larger than the size of the end away from the pneumatic motor 1 .

[0027] Furthermore, the extension mechanism 3 includes a connecting head 31, an end of the pneumatic motor 1 away from the shaking cleaning blade 2 is fixedly connected to the connecting head 31, an end of the connecting head 31 away from the pneumatic motor 1 is fixedly connected to a guide rail 32, an end of the guide rail 32 away from the connecting head 31 is symmetrically slidably connected to an inclined sliding rod 33, an end of the inclined sliding rod 33 away from the guide rail 32 is fixedly connected to a straight rod 34, one side of the straight rod 34 is equidistantly rotatably connected to a wall-attached roller 35, a rebound component 4 is provided on the inner side of the straight rod 34 and between adjacent wall-attached rollers 35, an end of the straight rod 34 away from the inclined sliding rod 33 is rotatably connected to a rotating connecting rod 36, an end of the rotating connecting rod 36 away from the straight rod 34 is provided with a handle, and both ends of the handle 37 are rotatably connected to the two rotating connecting rods 36 respectively, and the extension mechanism 3 facilitates better extension of the equipment, so that the shaking cleaning blade 2 can extend to the deeper part of the pipeline to clean the pipe wall, thereby increasing the cleaning range of the equipment.

[0028] Furthermore, the handle 37 is a U-shaped structure, the wall-adhering roller 35 is larger than the straight rod 34 , and the two inclined sliding rods 33 form an angle of sixty degrees.

[0030] Furthermore, armor is provided on the outside of the pneumatic motor 1. By setting up the armored air pipe, the equipment is made both rigid and flexible, ensuring the centrality of the combination of the high-speed pneumatic motor 1 and the shaking cleaning head 2 on the inner wall of the oil pipe, ensuring that the shaking cleaning head 2 is always in the best working state, and achieving the best descaling effect.

[0031] Specifically, when in use, first fix the pneumatic motor 1, the shaking cleaning blade 2 and the extension mechanism 3 together, then align the shaking cleaning blade 2 with the inside of the pipeline and insert it, then turn on the pneumatic motor 1, and push the shaking cleaning blade 2 deeper into the pipeline by pushing the pneumatic motor 1. The pneumatic motor 1 drives the shaking cleaning blade 2 to rotate, and the centrifugal force generated by the rapid rotation drives the shaking cleaning blade 2 to perform dry cleaning on the medium and heavy hard powder and hard solid scale on the inner wall of the oil pipe. When the pneumatic motor 1 penetrates into the pipeline, the gripping handle 37 is grasped to push the device into the pipeline, and the two straight rods 34 are pushed in parallel and away from each other by the spring 45, and then the wall-adhering roller 35 is fully fitted with the inner wall of the pipeline, driving the device to move deeper into the pipeline, so that the shaking cleaning blade 2 can clean the pipeline deeper.
