Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the drills on the existing cutter head are located at different positions, and the linear speed of the drills is different when the drill rod rotates, which in turn causes the wear of the drills to be different. The purpose is to provide a split rotation The raised drilling tool device solves the problem that the drilling tools on the existing cutter head are located in different positions, and the linear speed of the drilling tool is different when the drill pipe rotates, which leads to different wear degrees of the drilling tool.

Abstract

The invention discloses a split rotary raise boring cutter device. The split rotary raise boring cutter device comprises a drill rod, wherein a supporting table is arranged at one end of the drill rod; a first cutter head is connected to the supporting table; the inner wall of the first cutter head is connected with the outer wall of the drill rod; a second cutter head is further arranged at one end of the drill rod; the second cutter head is rotatably connected with the drill rod; the second cutter head is positioned inside the first cutter head; the second cutter head is connected with the first cutter head through a transmission mechanism; the rotation direction of the second cutter head is opposite to that of the first cutter head; a plurality of first fixed frames are arranged on the upper end surface of the first cutter head; the first fixed frames are positioned on a circle around the upper end surface of the first cutter head; first boring cutters are connected to the first fixed frames; a plurality of second fixed frames are arranged on the upper end surface of the second cutter head; the second fixed frames are positioned on a circle around the upper end surface of the second cutter head; and second boring cutters are connected to the second fixed frames. The split rotary raise boring cutter device solves the problem that the linear speeds of the boring cutters are different when an existing drill rod rotates, so that the wear degrees of the boring cutters are different.

Description

technical field [0001] The invention relates to a device, in particular to a split rotary raise drilling tool device. Background technique [0002] With the improvement of the efficiency requirements of the mine construction party, the overall performance of the drilling device needs to be comprehensively strengthened. Due to the influence of the size of the construction mine, it is difficult to arrange a sufficient number of cutters on the cutter head, resulting in low overall performance and difficulty in penetrating the mine at one time. , at the same speed, the hob bits on the outer periphery of the overall cutterhead work with a larger wire diameter than the hob bits on the inner periphery of the cutterhead, resulting in the linear speed of the outer cutterhead being much greater than that of the inner cutterhead, resulting in the outer hob The wear of the drill bit is much greater than the wear of the inner hob bit, and the outer hob bit wears too fast, resulting in th...
