Abstract

The invention provides a reciprocating-impact heading machine with a built-in rocker-arm telescopic cylinder. The reciprocating-impact heading machine comprises an outer telescopic drum, an inner telescopic drum, the telescopic cylinder, a reciprocating impact part and a machine body, wherein the inner telescopic drum is arranged in the outer telescopic drum; a joint of the inner telescopic drum and the reciprocating impact part is provided with an inner telescopic drum flange; the inner telescopic drum flange is connected with a box; the outer telescopic drum is mounted on the machine body; and the telescopic cylinder is arranged in the inner telescopic drum. According to the invention, an impact power supply member is transversely arranged, perpendicular to the box and isolated from an external severe environment, so the telescopic cylinder is effectively protected from invasion by pollution and from bumps and the like; the telescopic cylinder is arranged at a stress center, so uneven loading of the telescoping structure of a cutting part is avoided, telescoping of the cutting part is allowed to be smooth, and the service life of the cutting part is prolonged; the wall of the inner telescopic drum is provided with an inner drum water channel, so the heading machine is simple in structure and beautiful in appearance and prevents damage of a water pipe due to exposure; and since an oil outlet or a valve member is arranged at the rear part of the inner telescopic drum, maintenance is convenient, the internal diameter of the inner telescopic drum is decreased, and materials are saved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a reciprocating impact roadheader with built-in rocker telescopic oil cylinder. Background technique [0002] The cutting motor and transmission mechanism of the existing mining roadheader are vertically arranged, the motor power is large, the volume is large, the motor and the transmission mechanism are installed in the center of the telescopic mechanism, and there is no space to install the rocker telescopic oil cylinder, so the telescopic cutting part of the mining roadheader The telescopic oil cylinder is set on one or both sides of the outside. The environment in the coal mine is harsh, and the oil cylinder is set outside, which is seriously polluted by water and dust, rusted, and easily damaged. The oil cylinder is set on one side, and the eccentric load is serious during work. Component damage; currently, the waterway of the cutting part of the roadheader passes through the main t...
