In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1-2, the embodiment of the utility model provides a wet blasting machine telescopic boom frame dust collector sets up on telescopic boom frame 10, and telescopic boom frame 10 comprises first telescopic boom 11 and the flexible arm 12 of second, and the flexible arm 12 of second relies on the hydro-cylinder to promote can slide in first telescopic boom 11 to flexible operation carries out. The telescopic boom 10 is the prior art, and the detailed structure thereof is not described herein. The device comprises a plurality of dust removing mechanisms 20, wherein the dust removing mechanisms 20 are respectively arranged on all outer side surfaces of the first telescopic arm 11 in a one-to-one correspondence mode.

The dust removing mechanism 20 includes a support plate 21, a squeegee 22, and an adjustment assembly 30. The support plate 21 is arranged outside the first telescopic arm 11 and fixedly connected with the first telescopic arm 11, and the support plate 21 is inclined towards the direction close to the head of the second telescopic arm 12. The scraper 22 is arranged on the support plate 21 and is rotatably connected with the support plate 21 through a connecting piece 23, and the scraper 22 can be contacted with the corresponding outer side face of the second telescopic arm 12. The adjustment assembly 30 is used to adjust the angle between the blade 22 and the support plate 21, and thus the distance between the blade 22 and the second telescopic arm 12.

When the second telescopic arm 12 is performing telescopic operation, the scraper 22 will automatically clean the corresponding outer side surface of the second telescopic arm 12 to prevent dirt from entering the gap between the two arms, and further prevent the inner slide block structure from being damaged.
