DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A construction crusher comprises a crushing box 1, a pump water tank 2 is installed on the outer wall of the crushing box 1, a water spray ring 4 is arranged above the crushing box 1, and a plurality of atomizing nozzles 5 are arranged on the water spray ring 4. A rotating chamber 12 and an active chamber 13 are arranged inside the pump water tank 2. A reciprocating screw 8 extending to the top of the pump water tank 2 is rotatably arranged in the rotating chamber 12. A driving motor 7 connected to the reciprocating screw 8 is arranged on the outer wall of the crushing box 1 through a fixing mechanism. A piston plate 14 is provided in a sealing and sliding manner in the active chamber 13. The piston plate 14 is connected to the reciprocating screw 8 through a connecting mechanism. The active chamber 13 is connected to the water spray ring 4 through a water inlet pipe 3. The active chamber 13 is connected to a water source through a water suction pipe. An annular rotating groove is provided on the upper end surface of the crushing box 1. A rotating ring 6 is rotatably arranged in the annular rotating groove. The rotating ring 6 is connected to the reciprocating screw 8 through a rotating mechanism. A wiping rod 11 is provided on the rotating ring 6 through a support rod 10, and a wiping cloth is provided on the wiping rod 11.

[0021] The fixing mechanism includes a fixing ring fixedly arranged on the outer wall of the driving motor 7, the outer wall of the fixing ring is fixedly connected to the outer wall of the crushing box 1, the fixing ring realizes the rotation of the driving motor 7, and the reciprocating screw 8 is not provided with a thread on the outer wall outside the pump water box 2.

[0022] The connecting mechanism includes a connecting rod 15 threadedly mounted on the reciprocating screw 8, the end of the connecting rod 15 is fixedly connected to the outer wall of the piston plate 14, and the connecting rod 15 is L-shaped, and its end slides through the inner bottom wall of the rotating chamber 12 and extends into the active chamber 13. It has its own limit so that it will not rotate with the reciprocating screw 8.

[0023] The rotating mechanism includes a gear 9 arranged on the reciprocating screw 8, and a gear ring 17 meshing with the gear 9 is provided on the rotating ring 6. The teeth of the gear ring 17 are arranged on its arc-shaped outer wall and mesh with the teeth on the arc-shaped outer wall of the gear 9 to achieve power transmission.

[0024] A first one-way valve is provided in the water inlet pipe 3, and a second one-way valve is provided in the water suction pipe. The two one-way valves realize one-way flow operation of water.

[0025] An annular hidden groove 16 is provided on the arc-shaped outer wall of the rotating ring 6, and the gear ring 17 is arranged in the annular hidden groove 16.
