Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a lifting sandblasting gun for a dry sandblasting machine. Background Art

[0002] The suction dry sandblasting machine is powered by compressed air. The negative pressure formed in the spray gun by the high-speed movement of the airflow causes the abrasive to pass through the sand conveying pipe, be sucked into the spray gun and be ejected through the nozzle. In the prior art, the spray gun needs to be maintained after long-term use, and the sandblasting gun and the lifting equipment are fixed, which makes maintenance more difficult. At the same time, if a single sandblasting gun is damaged or the lifting equipment is damaged, it is impossible to separate them, resulting in the entire equipment being unusable, and it is inconvenient to separate the lifting equipment from the sandblasting gun.

[0003] For example, the authorized patent document with application number 202022321350.1 discloses a lifting sandblasting gun for a dry sandblasting machine, comprising a support base, a support plate fixedly connected to the top of the support base, a track rod fixedly connected to the top of the support plate, a lifting worm screw passing through the axis of the support plate, a fixed plate fixedly connected to the upper end of the track rod, a limit plate provided at the upper end of the lifting worm screw, a sandblasting head threadedly connected to the outer surface of the lifting worm screw, a sandblasting hole provided on the outer surface of the sandblasting head, a threaded hole provided on the axis of the sandblasting head, and a sliding hole provided on the surface of the sandblasting head.
