In that case, fine adjustment can be performed while the backhoe B is stopped by combining the movements of the arm B1 and the turning device 100. 8. After drilling at the required location, the worker walks to the site and moves from the hydraulic ceria carrier 80 to the hydraulic ceria 85.
Remove. Then, the rock is crushed using this. At this time, since the hydraulic ceria 85 is already near the hole-drilled portion, it is not necessary to draw the line tube, which facilitates the work.

Furthermore, since the hydraulic ceria carrier 80 is provided below the base body 2 of the boring machine body 1, it is easy to ground by operating the arm B1 of the backhoe B, and the hydraulic ceria 85 can be attached and detached. It is easy to perform each work such as oil line connection work. In addition, if the route to the drilling site is steep and dangerous, the slope of the site is steep, or the rock surface is exposed and slippery, there is a risk of work,
After that, the operator rides on the hydraulic ceria carrier 80 and moves to the site, and if necessary, the operator can crush the bedrock using the hydraulic ceria 85 while riding. The invention is not limited to the embodiments shown, but many variants are possible within the scope of the claims.
