Description
Technical Field
The utility model relates to a rock crushing equipment's field, concretely relates to wear-resisting material head of throwing of vertical shaft type breaker.
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.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a wear-resisting material head of throwing of vertical shaft type breaker, have that wear resistance is outstanding, material utilization is high and whole long service life's advantage.
The purpose of the utility model is accomplished through following technical scheme: the wear-resistant throwing head of the vertical shaft type crusher mainly comprises a base body and an alloy block, wherein a bolt hole is formed in the bottom of the base body, a sinking groove is formed in the top of the base body, and an opening is formed in one side, close to the bolt hole, of the top of the base body; the alloy block consists of a main body part and a boss part protruding outwards, the main body part is matched with the sink groove and embedded into the sink groove for installation and fixation, the boss part is matched with the opening for installation and fixation, and a chamfer is arranged at the boundary line of the main body part and the boss part.
Further, the substrate is made of cast structural steel or wear-resistant steel through a casting process.
Furthermore, the alloy block is made of hard alloy materials through a powder metallurgy process.
Further, the base body and the alloy block are connected through a brazing process or an adhesive process.
Further, the main body section of the main body part adopts a trapezoidal design or an arc design.
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.
