Embodiment Construction
[0015] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0016] refer to image 3 and Figure 4 , The drilling tool of the pile top drilling rig of the present invention includes: a tool holder 11, a cutter head 12, a disc hob 13, a cuttings collection device 14, and a chip removal hole 15. The disc-shaped hob 13 is arranged on the cutter head 12 along a plurality of uniformly distributed Archimedes spirals, and the...

The invention discloses a pile top drilling machine drilling tool. The tool includes a knife rest, a cutter disc, disc cutters, a cuttings collecting device, and a chip removing hole, wherein the disccutters are arranged on the cutter disc along multiple uniformly distributed Archimedes spirals, the cuttings collecting device is disposed between two of the multiple Archimedes spirals, the chip removal hole is disposed at the tail part of the cuttings collecting device and communicates with a main chip removing hole disposed in the knife rest, and the disc cutters are arranged and strewn at random on the cutter disc in a height direction, so that a cutting operation cross section of the pile top drilling machine drilling tool is of a "W" shape. By utilization of the pile top drilling machine drilling tool of the invention, drilling deflection caused by geology, equipment, operation and the like can be effectively reduced, the chip removal efficiency is significantly improved, and the drilling construction is ensured to be smoothly carried out.
Description
technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a drilling tool for a pile top drilling rig. Background technique [0002] On pile top drilling rigs and other similar drilling rigs, the drilling tool often adopts a disc hob structure. The arrangement of disc hobs mostly adopts the arrangement of concentric circles, such as figure 1 As shown, the disc-shaped hob structure in the prior art includes a cutter head 1 , a disc-shaped hob 2 , an earth and stone discharge hole 3 , and a central hob group 4 . The cutting operation section of the disc-shaped hob structure of the prior art is a plane or as figure 2 Conical convex surface shown. When using the disc-shaped hob structure of the prior art for drilling construction, due to factors such as geology, equipment, and operation, drilling deviation may occur, which will have an adverse effect on drilling construction. In addition, there is also the problem of low chip remo...
