Wet spraying machine and automatic speed regulation control method thereof
The invention discloses a wet spraying machine and an automatic speed regulation control method thereof. The wet spraying machine comprises a display on which a proportionality coefficient and an initial concrete pumping speed are set and are output, a flow meter which is arranged on a concrete pumping pipe, monitors a real-time concrete pumping speed and outputs the real-time concrete pumping speed, a stirrer which stirs concrete, a stirring motor which drives the stirrer, a rotating speed sensor which acquires a real-time stirring speed and outputs the real-time stirring speed, a proportional valve which changes the flow of a pipeline so as to regulate the output rotating speed of the stirring motor, a hydraulic pump which is connected to the proportional valve, a main motor which is connected to the hydraulic pump, and a controller which multiplies the real-time concrete pumping speed by the proportionality coefficient, calculates a corrected stirring speed, regulates the driving current of the proportional valve according to the corrected stirring speed, and compares the real-time stirring speed with the corrected stirring speed so as to perform closed-loop control.
