HOPPER OPEN-CLOSE DEVICE FOR PAVER

摘要

PROBLEM TO BE SOLVED: To smoothly convey asphalt mixture to the rear by facilitating the falling of the asphalt mixture when the asphalt mixture received in a hopper is charged into a conveyor device. SOLUTION: In a paver freely opening and closing the hopper side face section of a hopper device receiving the asphalt mixture by a hydraulic cylinder, an intermittent device is composed of a limit switch detecting the closing of the hopper side face section and a relay, a toggle switch selecting the open-close operation of the hopper side face section and a timber making an actuating signal to a lifting solenoid intermittent when the closing of the hopper side face section is detected.
