ABSTRACT:
An impact cutter implement consists of an actuator comprising a large-diameter cylinder in front and a small-diameter cylinder in the rear in coaxial alignment, a large piston and a small piston mounted on a common piston rod and axially movable in the respective cylinders, the piston rod protruding out of the large cylinder and forming a cutter at its front end. The frontal cylinder is connected to a large compressed air vessel, and the rear cylinder to a vessel containing oil, the two vessels being alternately connected to a compressed air supply and to the atmosphere by a valve. Pressurized oil holds the frontal piston in retracted position, until a valve between the oil vessel and the rear cylinder is opened, releasing the oil, whereupon the compressed air in the large air vessel drives the frontal piston forward at substantially uniform pressure and accelerating the cutter to a high impact velocity.
