ABSTRACT:
A block impact splitter is comprised of a support frame connected on a swivel to a stationary frame. A hammer is provided with a hammer head and secured to a pivotal arm pivotally connected to the support frame at a pivot connection. An actuating piston has a cylinder end thereof pivotally connected to the support frame and a piston rod end pivotally connected to the pivotal arm. The actuating piston displaces the hammer head to impact against a pitching blade assembly and to retract it therefrom. The pitching blade assembly has a pivotal support arm to which is secured a pitching blade. An adjusting mechanism positions the pitching blade relative to a block to be split along a parting slot of the block.
