Description
Technical Field
The utility model relates to a rock crushing equipment's field, concretely relates to stub bar is thrown to wear-resisting of vertical shaft breaker composite construction.
Background
A vertical shaft type impact crusher is a rock crushing device, which drives a stone block to rotate at a high speed by a central rotating component, when the stone block moves to the edge of a rotor, the stone block is thrown out at a high speed, and the ejected stone block collides with a lining plate or other stone blocks in the device, thereby realizing the crushing of the stone block. The part thrown by the stone at the edge of the rotor is called a throwing head, and is extremely easy to damage due to the strong abrasion of materials, so that the throwing head has strong abrasion resistance.
At present, the existing material throwing head is composed of a base body and a hard alloy strip, the hard alloy strip is generally in a cuboid structure, a groove is reserved in the base body, and the wear-resistant alloy strip is combined with the groove of the base body in an adhesive mode. Because the abrasion occurs at a local position, when the throwing head fails, the abrasion of the alloy strip is uneven, the local part of the hard alloy strip is worn through, and other parts are only slightly abraded, so that the waste of the hard alloy material is caused. Meanwhile, the work life of the throwing head is short due to the bad working condition of the throwing head, the throwing head is frequently replaced, and the production continuity is not facilitated. The current production conditions put higher demands on the overall performance of the throwing head.

The purpose of the utility model is accomplished through following technical scheme: the composite structure wear-resistant polishing head of the vertical shaft type crusher mainly comprises a base body, a composite structure wear-resistant body and a wear-resistant alloy block, wherein a base body sinking groove is formed in the base body, a boss matched with the base body sinking groove is arranged at the bottom of the composite structure wear-resistant body, the boss is embedded and installed in the base body sinking groove, so that the base body is fixedly connected with the composite structure wear-resistant body, the composite structure wear-resistant body is provided with a wear-resistant body sinking groove for embedding and installing the wear-resistant alloy block, and the wear-resistant body sinking groove is matched with the wear-resistant alloy block in shape; the base body is provided with bolt holes.
Further, the base body is made of cast structural steel or wear-resistant steel.
Furthermore, the composite structure wear-resistant body is made of high-chromium white wear-resistant iron or high-manganese steel wear-resistant materials through a casting process.
Further, the wear-resistant alloy block is made of hard alloy materials through a powder metallurgy process.
Further, the base body is connected with the composite structure wear-resistant body through a brazing process, and a border structure is arranged at the edge of the base body sink groove and used for containing welding liquid.
Furthermore, the composite structure wear-resistant body is connected with the wear-resistant alloy block through a brazing process or an adhesive process.
Furthermore, the wear-resistant alloy block can be designed into a single-side convex arc surface or a single-side polygonal cross section.
The utility model has the advantages that: the use efficiency of materials is effectively increased, the waste of hard alloy is reduced, and the cost is reduced; the product is ensured to have enough wear-resisting service life, and the cost performance of the throwing head is effectively improved.
