Abstract

PURPOSE:To detect the wear of a cutter bit and so on attached to a digging machine easily by leading a pressure resistance line from a position on a cutter frame whose wear is to be detected to a rear wall, enclosing pressure liquid into the line and detecting wear at the back of the rear wall. CONSTITUTION:A hole 14 with a suitable depth which does not penetrate into a wall up to the outside is cut inside a cutter bit, a pressure liquid enclosing tube 15 for detection is attached from the hole 14 up to the back of a rear wall 5 and a switching apparatus 16 and a pressure gauge 17 are fitted to the tube 15. Pressure liquid such as pressure oil is fed from the external into the pressure liquid enclosing tube 15 and the switching apparatus 16 is closed when the pressure gauge indicates a suitable pressure. When a cutter bit 6 is gradually worn away in digging and the wear reaches the hole 14, the pressure in the tube 15 is reduced and the operator can detects the wear of the cutter bit 6 by reading the indication of pressure gauge at the back of the rear wall 5. Thus, the wear of the cutter bit and so on can be detected easily on a safety place.
