Problems solved by technology
After the tooth head of the existing mining rock crusher is connected with the driving pivot, it will collide with the ore during work, thereby crushing the ore; but the tooth head of the existing rock crusher is made of hard metal material , under the impact and vibration of ore, the structure of the tooth head is easily damaged. Even if the working head of the tooth head is made of cemented carbide, but the structural design is not reasonable enough, it is easy to cause other parts of the tooth head to be impacted by the ore , so that the entire tooth head structure is damaged, and it is often necessary to replace the tooth head, which affects work efficiency and increases the cost of use

The invention discloses a stone crusher tooth. The stone crusher tooth comprises a cuboid blocky tooth body; the upper surface of the tooth body is a working surface, a cusp type tooth head is arranged at the front end of the working surface and is composed of two spliced blocky hard alloy blocks in front, the front end of each blocky hard alloy block is a tilted cusp type end face, and three side-by-side square hard alloy blocks are arranged at the part, located on the inner side of the tooth head, of the working surface in an embedded mode; and the lower surface of the tooth body is an assembling surface, and an oblique assembling surface transitioned through a middle arc and then obliquely inclined downwards is arranged from the middle to the rear end of the assembling surface. The stone crusher tooth has the advantages that the structure is reasonable, use and installation are convenient, the structure firmness of the whole tooth head is good, the wear resistance is high, the service life is prolonged, and the work efficiency is improved.
Description
technical field [0001] The invention relates to a rock crusher tooth, which belongs 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 tooth head of the existing mining rock crusher is connected with the driving pivot, it will collide with the ore during work, thereby crushing the ore; but the tooth head of the existing rock crusher is made of hard metal material , under the impact and vibration of ore, the structure of the tooth head is easily damaged. Even if the working head of the tooth head is made of cemented carbide, but the structural design is not reasonable enough, it is easy to cause other parts of the tooth head to be impacted by the ore , so that the structure of the entire tooth head is damaged, and it is often necessary to replace the tooth head, which affects work efficiency and increases the cost of use.
