[0003]

However, recent industrial waste is thrown away at a treatment plant surrounded by slopes, and rubber such as rubber is kept on the slopes to prevent harmful substances from leaching into the ground. Although the protection sheet is stretched, if the slope of the rock on the slope is severe, the weight of a hard block of concrete, such as concrete, in the input industrial waste will cause a cut in the surface of the protection sheet on the slope of the slope. , Hazardous substances could be leached into the ground and polluted groundwater. Therefore, it is necessary to eliminate the unevenness of the slope and make it flat.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a slope rock drilling machine which can finish a rough slope by blasting into a flat surface.

As shown in (a) of (1), if the stone is moved back and forth by moving 4,600 mm in the vertical direction, a slope with a width of 1 m and a length of 5.1 m can be cut. Further, as shown in (b), if the left and right movements are repeated and the vertical slope movements are repeated, a slope with a width of 1.1m and a length of 5m can be drilled.

The starting, stopping and direction switching of the patterns (a) and (b) can be visually inspected. However, in the case of automatic operation, limit switches attached to both left and right direction ends and front and rear direction both ends and a PC ( By the programmable control), the PC counts ON / OFF of each limit switch to perform each operation, and performs the work of patterns (a) and (b).

A proximity switch may be used instead of the limit switch.
