Pneumatic jumbolter

Abstract

The invention provides a pneumatic jumbolter. The pneumatic jumbolter comprises a gyrator, a supporting leg and a motion arm. One end of the supporting leg is fixedly provided with a fixed sleeve body, the gyrator is fixedly arranged on the fixed sleeve body, and the motion arm is hinged on the fixed sleeve body. The gyrator comprises a motor and a reducer, the motor drives a main shaft of the pneumatic jumbolte to rotate through the reducer, a silencer of the pneumatic jumbolte is arranged inside a shell of the motor, and a water inlet is formed in a shell of the reducer and communicated with a water channel of the main shaft so as to supply water to the main shaft; the pneumatic jumbolte is light in weight and small in size, reduces labor intensity and improves work efficiency. An exposed metal piece is made of stainless steel material, and therefore service life is prolonged, and the hidden danger of electrostatic sparks can be avoided; a motor gear and the supporting leg are made of composite material, and thereby being light in weight, corrosion resistant, flame retarding, antistatic, and long in service life; and the shell of the reducer is used for supplying water, a water jacket is eliminated, the weight of the jumbolter is reduced, and cost is reduced.

Description

technical field [0001] The invention relates to a mine drilling machine, in particular to a pneumatic rock bolt drilling machine. Background technique [0002] The pneumatic rock bolt rig integrates drilling, mixing, and installation of bolts and cables, and is suitable for anchoring and protection operations in various rock roadways, coal roadways, and semi-coal rock roadways with roof hardness f≤8. By changing the height and length of the outrigger legs and the control arm of the rock bolter, it is suitable for different roadway requirements. It is widely used in coal mines and has a very large demand. It is a necessary mining support tool, and now the pneumatic bolt The development of drilling rigs has reached a bottleneck, the weight cannot be reduced, and the hole-forming efficiency cannot be improved, which have become several major problems for designers and users. [0003] The structure of the existing pneumatic bolter consists of three parts: the gyrator 1', the ou...

AI Technical Summary

Problems solved by technology

[0008] (1) The traditional pneumatic rock bolter is heavy in structure, large in size and heavy in weight. The weight of the whole machine reaches 60kg, and the production efficiency is low;

[0009] (2) Most of the exposed parts are made of cast iron, cast aluminum, nylon and other materials, which are prone to rust, sparks, poor reliability and short service life
