The square structure of the hard alloy block is inserted into the caulking groove for welding, so that the binding force between the hard alloy block and the special-shaped body is increased, and the pointed structure of the hard alloy block protrudes out of the special-shaped body, so that the special-shaped body is prevented from being worn.
Preferably, the left side of the special-shaped body is provided with a large arc shape, the large arc shape is connected with the plane of the bottom of the special-shaped body, the rear side of the plane of the bottom of the special-shaped body is provided with a fixed cylindrical mounting hole, and the top of the special-shaped body is a large backward inclined plane. The contact area of the special-shaped body and the stone is increased by arranging a large arc shape on the left side of the special-shaped body, so that the crushing efficiency is improved.
Compared with the prior art, the utility model has the following advantages:
simple structure uses simple to operate, not only can improve the wearability and the life of product greatly, improves the work efficiency of equipment, can also effectively improve the crushing rate of material.
