Tooth head structure of stone crusher

Abstract

The invention discloses a tooth head structure of a stone crusher. The tooth head structure comprises a block-shaped tooth head body in the shape like a regular triangle from the lateral view. The upper face of the tooth head body is a work face. The front end portion of the work face is provided with a sharp-angle-shaped tooth head part. Outer protruding blocks are arranged on the two side faces of the tooth head body correspondingly, wherein the outer protruding blocks are integrated, the upper face work face serves as the boundary in a downward manner, and the area of the outer protruding blocks is larger than that of half of an end face. The tooth head part is arranged at the front end portion of the upper face work face of the outer protruding blocks. The tooth head part is mainly formed by connecting three large-block-shaped hard alloy blocks in parallel, wherein the three large-block-shaped hard alloy blocks are arranged in the front row. The front end portion of each large-block-shaped hard alloy is provided with an upwards-tilted sharp-angle-shaped end face. The upper face of the tooth head part composed of the large-block-shaped hard alloy blocks is higher than the work face. A whole-strip-shaped hard alloy block which is transversely arranged and is located on the same horizontal plane with the work face is further inlaid in the position, on the inner sides of the large-block-shaped hard alloy blocks, on the work face. The tooth head structure of the stone crusher has the beneficial effects of being reasonable in structure, convenient to use and install, good in overall tooth head structure firmness, high in wear resistance, capable of improving the work efficiency and the like.

Description

technical field [0001] The invention relates to a tooth head structure of a rock crusher, belonging to the technical field of ore machinery equipment. Background technique [0002] Mining stone crusher is a common mining powder equipment, usually used for primary crushing of ore. After the teeth of the existing mining rock crusher are connected with the drive pivot, they collide with the ore during work, thereby crushing the ore; but the teeth of the existing rock crusher are made of hard metal materials. As a result, under the impact and vibration of ore, the machine tooth structure is easily damaged. Even if the working head of the machine tooth is made of cemented carbide, but the structure design is not reasonable enough, it is easy to cause other parts of the machine tooth to be damaged by ore. The impact will damage the entire machine tooth structure, and the machine teeth need to be replaced frequently, which will affect the work efficiency and increase the cost of u...
