[0035] The installation chamber 3 is fixedly connected to one side of the transmission frame 1. An air pump 31 is fixedly connected inside the installation chamber 3. An air supply pipe is fixedly connected to the air pump 31. An air jet chamber 32 is fixedly connected to the air supply pipe on the air pump 31. An air supply pipe is fixedly connected to the air jet chamber 32. A feed chamber 33 is fixedly connected to the air supply pipe on the air jet chamber 32.

[0036] The air pump 31 drives the sand and gravel, causing air pressure changes that alter the shaft rotation speed. With the coordinated operation of a speed sensor, an electric telescopic rod 24, and a series of transmission components, abnormal sandblasting air pressure can be monitored in real time. This allows for a rapid response to sudden increases in the risk of sand splashing, promptly sealing the transmission frame 1 to prevent sand from scattering towards the operator. This effectively avoids sand impact injuries to the operator's eyes, face, neck, arms, and other parts of the body, greatly reducing the probability of accidents and creating a safe and worry-free working environment for the operator.

[0037] Furthermore, such as Figures 1 to 4 As shown, there are two air pumps 31. The air supply pipe on the air pump 31 on the side away from the jet chamber 32 is fixedly connected to the feed chamber 33. By setting two air pumps 31, air is supplied to the jet chamber 32 and the feed chamber 33 respectively.

[0038] The piston is slidably connected in the air injection bin 32 and the feeding bin 33, and when the air pump 31 supplies air into the feeding bin 33, the material is pressed into the bottom of the air injection bin 32, and the other air pump 31 works to push the piston in the feeding bin 33 to descend to spray the material.

[0044] Before use, first install the speed sensor in the mounting frame 23 and connect it with the electric telescopic rod 24;

[0045] The sand is poured into the feeding bin 33 through the feeding port of the transmission frame 1, the sand in the feeding bin 33 is pressed into the air injection bin 32 by starting the air pump 31, and the other air pump 31 is started to spray the sand on the workpiece;

[0046] When the air pressure of the air injection bin 32 downwardly sprayed is too large, the rotating speed of the first rotating shaft 21 is increased, the speed sensor captures the rotating speed change, the electric telescopic rod 24 is controlled to rise, the second rotating shaft 25 is driven to lift, the sliding block 27 is rapidly pressed downwardly, and the sealing plate 22 is driven to seal the transmission frame 1, so that the sand is prevented from being sprayed on the body of the worker.
