Crusher tooth head of stone crusher

Abstract

A crusher tooth head of a stone crusher comprises a blocky tooth head body with the side-looking shape being similar to a regular triangle. The upper surface of the tooth head body is a working surface, and sharp-corner type tooth head parts are arranged at the front end of the working surface. Integrated outwards-protruding blocks are arranged on the two side faces of the tooth head body correspondingly, the working surface on the upper side downwards divides the outwards-protruding blocks, and the area of the outwards-protruding blocks is larger than half of the area of the working surface. The tooth head parts are arranged at the front ends of upper working surfaces of the outwards-protruding blocks. An oblique-plane notch groove with the width larger than one third of the whole width of each tooth head part is obliquely downwards formed in the middle of the tooth head part from the middle position of the corresponding working surface. Two large blocky hard alloy blocks are arranged on the portions, located on the two sides of the oblique-plane notch groove, of each tooth head part correspondingly. The sharp-tip end face tilting upwards is arranged at the front end of each large blocky hard alloy block. Each tooth head part composed of the large blocky hard alloy blocks is higher than the corresponding working surface. A small blocky hard alloy block located on the same horizontal plane with each working surface is embedded into the portion, located on the inner side of the corresponding large blocky hard alloy block, of the corresponding working surface. The crusher tooth head of the stone crusher has the characteristics that the structure is reasonable, using and mounting are convenient, the whole tooth head is good in structural firmness and resistant to abrasion, and thus the using cost is lowered, and work efficiency is improved.

Description

technical field [0001] The invention relates to a tooth head 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 use. Cont...

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. Impact, so that the entire machine tooth structure is damaged, and the machine teeth need to be replaced frequently, which affects work efficiency and increases the cost of use
