Abstract

The invention relates to mine excavation equipment, and in particular to a reciprocating impact tunnel boring machine. The machine comprises a machine body with a walking mechanism; the reciprocating impact tunnel boring machine also comprises an impact rotary drilling mechanism comprising an impact device, a rotary drilling device and a drill; the rotary drilling device is slidably connected with the drill; the rotary drilling device drives the drill to rotate; the impact device impacts the drill; the drill rotates for impact; the impact device cooperates with the rotary drilling device to drive the drill for impact rotation; the impact rotary drilling mechanism is arranged on the machine body; the walking mechanism drives the machine body for walking; the machine body walks to block back the drill through the rock; and the drill rotates for reciprocating impact. The reciprocating impact tunnel boring machine changes an excavation way only conducting drilling without reciprocating impact of an original boring machine, and a cutting part drills while reciprocating for impact, so as to improve driving efficiency, greatly improve drilling efficiency, optimize boring working environment, and greatly reduce energy consumption of the mining machine.

Description

technical field [0001] The invention relates to a mine excavation equipment, in particular to a reciprocating impact drilling machine. Background technique [0002] The currently widely used mining excavation equipment is mainly the cantilever type roadheader. Its working principle is drilling tunneling, which determines that the grinding and crushing of this tunneling method is relatively large, especially in the state of compressive stress, which consumes a lot of energy and reduces the productivity of tunneling. The advancement of the drill bit is completed by the walking of the fuselage , in order to make the drill bit drill quickly, the thrust of the machine body to speed up the progress of the excavation continues to increase, causing greater damage to the machine body. [0003] The patent number is 200620137402.7, and the name is "small energy-saving impact coal shearer" which discloses a coal shearer with an impact arm and an impact head. The output of the motor is...
