Abstract

The invention discloses a tunneling drilling rig and relates to the technical field of tunneling equipment. The tunneling drilling rig can improve the tunneling efficiency. The tunneling drilling rig comprises a drilling rod, a rotating driving mechanism and a pushing mechanism, wherein the rotating driving mechanism drives the drilling rod to rotate, the pushing mechanism drives the drilling rod to conduct back and forth movement, a port is formed in one end, used for drilling in a working surface to conduct the drilling-in work, of the drilling rod, a hollow structure used for containing drilling materials is arranged inside the drilling rod, and the hollow structure is communicated with the port. The tunneling drilling rid is suitable for the drilling and tunneling of the working surface such as rock.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a drilling rod of the drilling machine. Background technique [0002] The roadheader in the prior art includes a drill rod and a driving device that drives the drill rod to rotate. A drill bit is installed at the end of the drill rod, and a slag guiding groove is provided on the outside of the drill rod. During the drilling operation, the drill bit will The rocks on the working face are crushed first, and the crushed rocks are exported out of the hole through the ballast groove. [0003] In the existing drilling equipment of this kind, during the drilling operation, it is necessary to completely break and export the rocks in the hole, the drilling speed is slow, and the driving efficiency is low, especially in large-diameter tunnels. This inefficiency in driving is even more pronounced during drilling operations. Contents of the invention [0004] The technical problem solved by the pres...
