Abstract
A self-contained material handling and shearing attachment for a backhoe enables the backhoe to be used in grasping and moving structural beams, pipes, cables, and the like, and pivotally positions a cutting blade in the form of a hook on the end of a backhoe boom for actuation by a self-contained piston and cylinder assembly. A fixed blade is secured to the attachment forming a shear point between the movable cutting blade and the fixed blade. The fixed and movable blades are shaped and positioned relative to their pivotal engagement to move objects being sheared towards the blade's pivotal engagement rather than away therefrom and does not require the use of the piston and cylinder of the backhoe as is known in prior art shears.
Claims6
An improvement in a cutting and manipulating attachment for a backhoe, the bucket of which has been removed and having a boom and means for moving the boom;
- the improvement comprising a mounting body defining an elongated cavity arranged to receive a portion of said boom, means for attaching said mounting body to said boom, an elongated movable cutting blade having a pair of cutting edges arranged in a V-shape on a common plane parallel with said cutting blade, said cutting edges positioned in shearing relation to a fixed cutting blade on said mounting body, means pivotally mounting said elongated cutting blade on said mounting body in pivotal relation to said fixed cutting blade with at least one of said cutting edges arranged in approximately parallel spaced relation to said fixed cutting blade when said elongated movable cutting blade is in substantially open relation thereto, means on said mounting body for keeping said elongated movable cutting blade in shearing relation to said fixed cutting blade consisting of spaced parallel guides adjacent said fixed cutting blade defining an elongated guide path for a portion of said movable elongated cutting blade, a piston and cylinder positioned on said mounting body and pivotally connected to said movable cutting blade so that the same can be moved relative to said fixed body thereby.
