The current main model of wet concrete shotcrete machine is rotor type concrete wet spray machine, which has the advantages of uniform discharge, compact structure, low working dust concentration, less rebound and high strength of shotcrete. It is widely used in mine anchor spray. Protection, tunnel engineering, construction sites and other fields.
The working principle is as follows: the motor drives the reducer through the coupling, and the output shaft of the reducer drives the rotor to rotate, and drives the hopper on the hopper to rotate, and the concrete mixture falls into the rotating rotor cavity through the hopper. After the rotor rotates through 180°, the compressed air communicates with the air inlet of the material chamber. Under the action of the gas, the material is sent to the nozzle through the discharge elbow and the delivery pipe, and water is sprayed out at the nozzle.
