[0010] The working principle of this utility model is as follows: When cleaning garbage by moving the chassis frame, when it is necessary to remove most of the garbage or lighter garbage at the curb, hydraulic motor A and hydraulic motor B are turned on at the same time. Hydraulic motor A drives fan A to run, and fan A blows air to the air outlet pipe A. Hydraulic motor B drives fan B to run, and fan B blows air to the air outlet pipe B.

[0011] When it is necessary to blow away the garbage on the left side of the chassis frame, the lifting cylinder A is activated. The main shaft of cylinder A drives the connecting plate A, which in turn drives the rotating shaft A to rotate. The rotating shaft A drives the wind deflector A to approach the lower right side of the conical tube. The lifting cylinder A is then stopped. The air generated by the blower A passes through the air outlet pipe A, the serpentine air guide pipe A, and the left side of the L-shaped plate and blows into the conical tube. The air generated by the blower B passes through the air outlet pipe B, the serpentine air guide pipe B, and the right side of the L-shaped plate and blows into the conical tube. The air inside the conical tube passes through the rectangular bucket and the arc-shaped pipe A to blow away the garbage on the left side of the chassis frame along the road surface.

[0012] When it is necessary to blow away the garbage on the right side of the chassis frame, the cylinder A retracts. The main shaft of cylinder A drives the connecting plate A, which in turn drives the rotating shaft A to rotate. The rotating shaft A drives the wind deflector A to approach the lower left side of the conical tube. The cylinder A retracts and stops. The air generated by the blower A passes through the air outlet pipe A, the serpentine air guide pipe A, and the left side of the L-shaped plate and blows into the conical tube. The air generated by the blower B passes through the air outlet pipe B, the serpentine air guide pipe B, and the right side of the L-shaped plate and blows into the conical tube. The air in the conical tube passes through the rectangular barrel and the arc-shaped pipe B and blows away the garbage on the right side of the chassis frame on the road surface that the chassis frame passes through.

[0013] When it is not necessary to blow away the garbage, the lifting cylinder B is activated. The main shaft of cylinder B drives the connecting plate B, which in turn drives the rotating shaft B to rotate. The rotating shaft B drives the baffle plate B to block the air inlet at the top of the serpentine air duct A. The air generated by the blower A is blown out through the air outlet pipe A. The lifting cylinder B is then stopped. The lifting cylinder C is activated. The main shaft of cylinder C drives the connecting plate C, which in turn drives the rotating shaft C to rotate. The rotating shaft C drives the baffle plate C to block the air inlet at the top of the serpentine air duct B. The air generated by the blower B is blown out through the air outlet pipe B. The lifting cylinder C is then stopped.

[0014] When it is necessary to blow out the waste again, cylinder B retracts. The main shaft of cylinder B drives the connecting plate B, which in turn drives the rotating shaft B to rotate. The rotating shaft B drives the baffle plate B to block the upper part of the inner wall of the air outlet pipe A. Cylinder B stops retracting. Cylinder C then retracts. The main shaft of cylinder C drives the connecting plate C, which in turn drives the rotating shaft C to rotate. The rotating shaft C drives the baffle plate C to block the upper part of the inner wall of the air outlet pipe B. Cylinder C stops retracting. The above actions are repeated to continue working.
