Problems solved by technology

Its defect is that the coal shearer only performs reciprocating impact and does not perform drilling and excavation functions.
[0004] The patent application number is 201210006183.9, and the name is "reciprocating impact drilling machine". , the kinetic energy absorption of reciprocating impact consumes a lot, so the energy consumption is too large, the practical work is small, and because the drill bit slides back and forth, the forward propulsion force is weakened during the rotation of the drill bit, which reduces the effect of part of the rotating action on the material , causing the drilling force of the drill bit to decrease during the return stroke of the reciprocating impact action

Abstract

The invention relates to mining excavation equipment, in particular to a boring machine with a reciprocating direct-impact effect. The boring machine comprises a machine body comprising a travel mechanism and further comprises an impact mechanism and a rotary-drilling mechanism, wherein the impact mechanism comprises an impact device and an impact head, the impact head is arranged at the front part of the impact device, the impact device drives the impact head to impact, the rotary-drilling mechanism comprises a rotary-drilling device and a drilling bit, the drilling bit is arranged at the front part of the rotary-drilling device, the rotary-drilling device drives the drilling bit to perform rotary drilling operation, and the impact head of the impact mechanism is arranged at the middle part and / or the lateral part of the drilling bit of the rotary-drilling mechanism. The impact mechanism and the rotary-drilling mechanism are arranged on the machine body, and the travel mechanism drives the whole boring machine to move. The tunneling efficiency is increased, the drilling efficiency is greatly increased, the boring kinetic energy is utilized to the greatest extent, the damping to the rotation of the drilling bit is eliminated during reciprocating impact of the drilling bit of the boring machine, the toothed bit can penetrate and destroy materials more easily, and the impact life of the impact head is increased.

Description

Technical field [0001] The invention relates to a mine excavation equipment, in particular to a reciprocating direct impact drilling machine. Background technique [0002] Currently widely used mine tunneling equipment is mainly cantilever tunneling machine. Its working principle is drilling-type tunneling, which determines that the tunneling method is relatively large in grinding and crushing, especially in the state of compressive stress, which consumes a lot of energy and reduces the productivity of tunneling. The advancement of the drill is completed by the walking of the body. In order to make the drill drill fast and speed up the progress of the tunneling, the thrust of the fuselage is continuously increased, causing greater damage to the fuselage. The fundamental defect is that the drill only grinds and drills and cannot be impacted. [0003] The patent number is 200620137402.7 and the name is "Small Energy-saving Impact Shearer". It discloses a shearer with an impact arm a...
