動たがね装置。In an automatic chisel device in which the head of a chisel is struck with a piston that moves inside the piston sliding hole of a cylinder by the pressure of compressed air, the piston sliding hole is moved from near the center to the rear with a large diameter step. A stepped piston having a large diameter near the rear end is inserted into the piston sliding hole so as to be reciprocally movable, and the piston has a passage penetrating from the front outer peripheral surface to the rear surface. A hole is formed therethrough, and a recess adjacent to the piston sliding hole and having a larger diameter than the piston sliding hole is formed inside the cylinder at a forward position, and the recess is communicated with the atmosphere through an exhaust hole. Excluding the exhaust hole (a container is attached to the rear outside to define an air chamber, and the air chamber is connected to the large diameter part of the piston sliding hole through an air supply hole provided through the body of the cylinder). The air supply hole is opened and closed by a valve mechanism, and when the piston is in the backward position C, a hollow chamber defined by the large diameter part of the piston sliding hole and the piston is connected to the air supply hole near the front end of the piston. communicates with the front end of the ventilation hole,
The automatic chisel device is further characterized in that when the piston moves forward, the front end of the vent hole of the piston enters into the recess.
