Mechanical arm mining machine

Abstract

The invention discloses a mechanical arm mining machine. The mechanical arm mining machine structurally comprises a crushing rod, a base, a mounting plate, a first mounting seat, a first mechanical arm, a first hydraulic cylinder, a second hydraulic cylinder, a second mechanical arm, a second mounting seat and a third hydraulic cylinder, wherein one end of the second mechanical arm is connected with the second mounting seat, and the other end of the second mechanical arm is connected with the first mechanical arm. Compared with the prior art, the mechanical arm mining machine has the beneficial effects that through combined arrangement of bolts, nut sleeves, a plate body, clamping and fixing mechanisms, nut sleeves, threaded holes and pneumatic sets, the bolts and nuts can be prevented from being exposed outsides, the bolts and the nuts are effectively prevented from being oxidized and rusted, and the bolts and the nuts can be disassembled conveniently; and meanwhile, the clamping andfixing mechanisms can limit, clamp and fix the bolts and the nuts, so that the bolts and the nuts are effectively prevented from loosening under the action of vibration force, then the bolts and the nuts can be prevented from falling off, the safety performance of the mechanical arms is improved, the mechanical arms are well protected, and the damage rate of the mechanical arms is reduced.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a mechanical arm mining machinery. Background technique [0002] The mining machinery industry is one of the important basic industries that provide equipment for the mining and processing of solid raw materials, materials and fuels. It serves important basic industrial sectors such as ferrous and nonferrous metallurgy, coal, building materials, chemicals, and nuclear industries. Its products are used in transportation, There are also a large number of applications in the basic construction of railways, construction, water conservancy and hydropower, etc. With the rapid development of machinery, it is widely used in mining.

AI Technical Summary

Problems solved by technology

[0003] As far as the crushing mechanical arm is concerned, the existing mechanical arm and the crushing rod seat are installed through bolts and nuts, and the bolts and nuts are directly exposed to the outside, easy to oxidize and rust, and it is difficult to disassemble the bolts and nuts after rusting In addition, the bolts and nuts are easily loosened by the vibration force generated during the operation, which will cause the bolts and nuts to fall off for a long time, making the safety performance of the mechanical arm low and easily causing damage to the mechanical arm
