Abstract

The utility model discloses a detachable crusher hammer, which relates to the technical field of crushers and comprises a hammer body and a hammer head, wherein the hammer head is assembled at the top of the hammer body, the whole hammer body is cylindrical, the bottom of the hammer head is cylindrical, the middle part of the hammer head is in a truncated cone shape, the tip of the hammer head is in a cone shape, and a coating is deposited on the top of the hammer head. According to the utility model, the stud protruding from the top of the hammer body and the concave threaded hole at the bottom of the hammer head are arranged, so that the hammer head part can be assembled and disassembled conveniently. The included angle between the tip of the hammer head and the horizontal plane is smaller than the included angle between the middle part of the hammer head and the horizontal plane, a blunt sharp angle is formed, and in the crushing process, the stress generated when the hammer head directly collides with the material is dispersed, so that the service life is prolonged. The overlay film is overlaid on the top of the hammer head, so that the hardness and rigidity of the hammer head are improved, and the efficiency of crushing the silicon blocks is further improved.

Description

Detachable breaker hammer Technical Field The utility model relates to the technical field of crushers, in particular to a detachable hammer head of a crusher. Background Industrial silicon, also called metallic silicon, is produced by drying and smelting silicon mud. Specifically, wet silicon mud is put into a special oven for drying and then transferred to an intermediate frequency furnace for smelting and impurity removal. The silicon mud is a low-temperature antioxidant, soft is common, the hand feeling is fine and smooth, the weight is light, the silicon mud is porous and strong in water absorption, dust is easily generated when the dried silicon is exposed in the air, and industrial silicon prepared by smelting in an intermediate frequency furnace has the characteristics of hardness and brittleness. In view of the different characteristics of silicon materials at different stages in the industrial silicon production process, there are many problems to be solved in the processes of drying, transferring, smelting, crushing and the like. In the material crushing stage, the silicon blocks after smelting have the characteristics of high hardness and high brittleness, so that high requirements are put on crushing equipment. Referring to Chinese patent, publication number CN 203061215U discloses a novel toothed roller type coal crusher, which comprises a crushing mechanism, a transmission system and a frame assembly, wherein the crushing mechanism comprises two crushing toothed rollers which rotate relatively, and picks of the crushing toothed rollers are in bullet shape. The bullet-shaped tooth tip adopts smooth transition design, so that stress concentration phenomenon during direct collision with materials is reduced, and the service life of the tooth tip can be prolonged. However, when the bullet-shaped crushing tooth roller is used in actual production, abrasion is increased when the bullet-shaped crushing tooth roller is meshed with materials, tooth tips are easy to damage, and as the tooth tips are fixedly welded on the tooth roller, the tooth tips can only be replaced in a whole piece after being damaged, so that the production cost is increased. Disclosure of utility model The utility model aims to provide a detachable crusher hammer head, which solves the problems. The utility model provides a detachable breaker tup, includes hammer body, tup, and the hammer body top is equipped with the tup, and the hammer body entire body is cylindric, and the shape of the bottom of tup is cylindric, and the shape at the middle part of tup is round platform form, and the shape of the tip of tup is coniform, and the top build-up welding of tup has the tectorial membrane. Preferably, the material of the coating is tungsten carbide. Preferably, the top of the hammer body is provided with a convex stud, the bottom of the hammer head is provided with an inner concave threaded hole matched with the size of the stud, and the stud is screwed after being aligned with the inner concave threaded hole. Preferably, the included angle between the tip of the hammer head and the horizontal plane is smaller than the included angle between the middle part of the hammer head and the horizontal plane. Compared with the prior art, the utility model has the beneficial effects that: 1. According to the utility model, the hammer head part can be assembled and disassembled conveniently through the stud protruding from the top of the hammer body and the concave threaded hole at the bottom of the hammer head. 2. According to the utility model, the included angle between the tip of the hammer head and the horizontal plane is smaller than the included angle between the middle of the hammer head and the horizontal plane, so that a blunt sharp angle is formed, and in the crushing process, the stress generated when the hammer head directly collides with the material is dispersed, and the service life is prolonged. 3. According to the utility model, the coating is overlaid on the top of the hammer, so that the hardness and rigidity of the hammer are improved, and the efficiency of crushing the silicon blocks is further improved.
