Description
Technical Field
The utility model relates to the technical field of machinery, especially, relate to a double-end type rubble tooth head.
Background
The crusher is a common large crusher, a tooth head of the crusher is a consumable product which is very easy to damage, so that the tooth head can be durable, under a common condition, alloy materials are embedded on the surface of the tooth head or in the tooth head, the tooth head is more wear-resistant, the tooth head is not uniformly worn due to the fact that the alloy materials are arranged on the surface or embedded in the tooth head, the whole surface is embedded possibly, only a small block is formed when the tooth head is seriously worn, the abrasion is very waste, and the shape of the tooth head is also very related to the position of abrasion.
Disclosure of Invention
The utility model aims to overcome prior art not enough and provide a structural design is reasonable, and the installation is fixed convenient, and is wear-resisting, the fastness is strong, long service life, reduces use cost, improves work efficiency's a double-end type rubble tooth head.
The utility model aims to realize the purpose by the following technical proposal that a double-head type stone-crushing tooth head comprises a tooth head body, the upper part of the tooth head body is a working surface, the lower part of the tooth head body is an assembly surface, one end of the upper working surface is provided with an upward-raised sharp-angle-shaped tooth head part, the other end is provided with a rectangular working plane, the tooth head part is vertically connected with the working plane to form an L-shaped working plane, a positioning hole which is directly communicated to the bottom assembly surface is arranged in the working plane, an inclined front surface is arranged below the tooth head part of the working plane, the oblique front surface extends to the two side legs of the bottom part all the way, the rear end of the assembly surface of the bottom part is provided with an assembly bulge which protrudes downwards, the assembly bulge is internally provided with a positioning hole communicated with the working plane, and the leg column at the bottom, the assembly bulge and the assembly surface form an inverted U-shaped assembly bottom surface.
Preferably, the method comprises the following steps: an embedded groove is transversely and downwards arranged at the head part of the tooth with the top point angle shape on the working surface, and two hard alloy block heads which are arranged side by side and are in a herringbone shape are transversely embedded and fixed in the embedded groove; the two side-by-side hard alloy block heads form an M-shaped working tooth head, and two sides of the working tooth head extending along the two side edges of the body are provided with a slope-shaped fixing groove for fixing the tooth base.
The utility model belongs to the improvement to prior art, it has structural design rationally, and the installation is fixed convenient, and is wear-resisting, fastness is strong, long service life, reduces use cost, improves characteristics such as work efficiency.
