DETAILED DESCRIPTION

[0015] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0016] according to Figure 1-4 As shown, a shot blasting machine that is easy to clean, a frame 1, an active roller 3 and two transmission rollers 4 are arranged inside the frame 1, the active roller 3 and the transmission roller 4 are distributed in a triangle, and a track 2 is provided on the outer wall of the active roller 3 and the transmission roller 4. A cleaning brush 5 is provided under the track 2, and the roller shaft 6 of the cleaning brush 5 has a hollow structure. A dust suction hole 7 is provided on the roller shaft 6. The end of the cleaning brush 5 is equipped with a driving assembly for driving it to rotate, and the end of the cleaning brush 5 is connected to the dust suction device 8 through a pipe.

[0017] In the above specific embodiment, the workpiece is placed on the crawler 2, and the crawler 2 is rotated by the active roller 3 and the transmission rod 4. The crawler 2 can flip the workpiece during the rotation, so that the ejected steel balls can better clean the workpiece. A cleaning brush 5 is provided under the crawler 2 to clean the powder and impurities adhered to the crawler 2. A dust suction hole 7 is provided on the roller 6 to suck the cleaned powder into the roller 6 and discharge it through the dust suction device 8, making it easy to clean the crawler 2.
