Embodiment Construction
[0035] In view of this, the core of the present invention is to disclose a high-pressure water jet double-slit coupling rock-breaking tunneling machine, which reduces the wear of the hob.
[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as Figure 1-Figure 5 As shown, the present invention discloses a high-pressure water jet double-slit coupled rock-breaking tunneling machine, which includes a cutter head 1, a spraying device and a high-pressure water generating device. Wherein, the hob 2 is installed on the first side of the cutterhead 1, and the hob 2 is a cutter for breaking rocks. In practice, multiple hobs 2 may be installed on the cutterhead 1, and the installation positions will be along the The circumferential arrangement of the disk 1; in order to reduce th...
