Reciprocating impact mining method for setting discharge hole and discharge and reciprocating impact mining machine for setting discharge hole discharge to realize the method

Abstract

The invention proposes a reciprocating impact excavation method for setting a discharge hole for discharging materials and a reciprocating impact mining machine for setting a discharge hole for discharging materials to realize the method. The impact and blanking mechanism includes an impact power box, a power impact member, an impact guide, and an impact head. , the impact head is composed of a support seat, a discharge hole frame, a punching tooth or is composed of a support seat and a punch tooth. The discharge hole frame is set on the support seat. The hole is conducive to the outflow of the material punched by the inner layer material teeth. The impact and blanking mechanism is set on the machine body, and the traveling mechanism is set on the machine body. The body passes through smoothly, realizing continuous excavation, which solves the problem that the excavator cannot excavate continuously due to the inability to discharge the material sandwiched between the tooth heads, and realizes the smooth excavation, discharge, and loading of the excavator with the impact head, and improves the excavation efficiency. .

Description

technical field [0001] The invention belongs to the field of machinery, and is especially suitable for the mining field, and in particular relates to a reciprocating impact excavation method with a discharge hole and a reciprocating impact mining machine for implementing the method. Background technique [0002] The impact heads of impact mining machines such as existing punching mining equipment are generally single-layer or multi-layer impact heads. The inner impact head and the outer impact head of the multi-layer impact head are mostly arranged close to each other. When the punching teeth of the inner impact head are set in one row and the punching teeth are rare, the impact resistance of the punching teeth will increase a lot if the excavation width is slightly wider. The material punched by the over-dense inner layer punching teeth cannot pass through, that is, the inner impact head close to the material layer sandwiches the material between the inner and outer impact...

AI Technical Summary

Problems solved by technology

In order to solve the problem of extruding material between the impact heads, the present invention sets a discharge hole on the impact and blanking mechanism, and makes the shape and / or arrangement of the material teeth of the outer layer of the punching material beneficial to the material teeth of the inner layer of the punching material. The structure of the material outflow, the invention of this structure greatly reduces the extrusion damage to the material block, reduces the resistance of the punching teeth, and solves the problem that the material sandwiched between the two impact heads cannot be discharged when the previous multi-layer impact heads are excavated. Multi-layer impact head excavator cannot continuously produce obstacles, improving the service life of the equipment
