A hammerhead structure of a crusher is disclosed. The hammerhead structure comprises a hammerhead shaft sleeve which sleeves and is mounted on a crusher roll shaft by utilizing a shaft hole, a hammerhead body is integrally connected on the upper surface of the hammerhead shaft sleeve through a shaft neck, wherein the hammerhead body is a hexahedron, two kinds of ellipse-shaped cemented carbide with different sizes are evenly and alternately arranged on the working surfaces of the front portion and the upper portion of the hammerhead body correspondingly, and hard welding strips with large areas are welded on the two side surfaces corresponding to the working surfaces; and a sharp angle smaller than 90 degrees is formed between the working surfaces of the right front portion and the upper portion of the hammerhead body, the lower portion of the hammerhead body is integrally connected to the cylinder-shaped hammerhead shaft sleeve provided with the shaft hole through the connecting shaft neck which is smaller than the hammerhead body, an arc structure connecting surface is formed between the front portion of the hammerhead body and the shaft neck, and a hard welding strip with a large area is welded on the arc structure connecting surface. The hammerhead structure has the characteristics that the structure is simple, usage and installation are convenient, the impact strength can be enhanced, the wear is reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to a hammer head structure of a crusher, which belongs to the technical field of crushers. Background technique [0002] Crusher is widely used in the operation of crushing materials. For example, in the ironmaking process of ore, including the natural iron ore to be mined, after crushing, grinding, ore dressing and other processes, fine particles with high iron content are screened out, called iron concentrate. When the crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly, and the high-speed rotating hammer head impacts, shears and tears the material, causing the material to be broken. At present, a single hammer head is mostly used, which is easy to replace and reduces the cost of use. However, due to the simple structure of the existing hammer head, the impact strength is low, and it is easy to wear and tear, thereby affecting the work efficiency. Content...
