[0012] Compared with the prior art, the advantages and positive effects of the utility model are:
[0013] In the utility model, by arranging a knocking component and an auxiliary component, when the equipment is working, the operator can remotely control the equipment to work through an operating handle connected to the equipment. When the equipment is working, the spray gun is energized to cooperate with the conduit to extract the concrete in the storage bin and spray it evenly onto the wall. When the spraying operation of one area is completed, the staff operates the chassis to work, and the chassis drives the crawler to move the equipment forward or backward; when the equipment completes the operation and the nozzle of the spray head is aimed at the ground, the switch of the servo motor is turned on, and the servo motor is energized to cooperate with the assembly sleeve to drive the pressing cam to rotate counterclockwise.

When the pressing cam rotates and disengages from the connecting frame, the connecting frame loses the pressure applied to the reset spring, and the reset spring loses the pressure and rebounds, and pushes the connecting frame to reset. The connecting frame pushes the connecting shaft under the action of the reset spring, and the connecting shaft cooperates with the supporting arm to push the knocking hammer. The knocking hammer is pushed to knock the sprinkler head. The servo motor drives the pressing cam to rotate cyclically, so that the knocking assembly works reciprocatingly, thereby vibrating the sprinkler head and shaking off the attached concrete in the sprinkler head. By setting the knocking assembly and the auxiliary assembly, the equipment can quickly clean the auxiliary concrete inside the spray gun after completing the work, thereby reducing the problem of concrete remaining in the spray gun, which is easy to interfere with the normal operation of the spray gun, and further improves the equipment's treatment effect on residual concrete.
