Of course, it may be configured such that the guide column 111 of the guide tower 110 and the slide table 120 are slidable via a bearing, and various means can be adopted for the slide mechanism.
The slide table 120 is configured to descend and ascend the guide tower 110 by self-propelled means. This self-propelled means will be described later.
A drilling machine main body 130 is mounted on the slide table 120.

  The drilling machine main body 130 is detachably attached to the slide table 120 with screws or the like. The drilling machine main body 130 is provided with a compressed air inlet 131, and is configured such that an external compressed air tube 141 is detachably connected thereto. The drilling machine main body 130 is provided with an oil introduction port 132 for hydraulic pressure, and is configured to be connected to an external hydraulic tube 142 (see FIGS. 7, 9, and 10).

The drilling rod 150 extends from the drilling machine main body 130 along the center line of the guide tower 110. That is, when the guide tower 110 is erected vertically to the ground, the guide tower 110 is suspended from the drilling machine main body 130.
A drill bit 151 is provided at the tip of the drill rod 150, and the rock surface of the slope S is actually drilled by the hard drill bit 151.
The drilling rod 150 is shaped like a pipe so that a part of the compressed air introduced into the drilling machine main body 130 passes through the inner hole of the drilling rod 150 and is ejected from the drilling bit 151 at the tip. .
Further, the drilling rod 150 is configured such that a plurality of drilling rods 150 can be added.

Referring also to FIG. 11, the compressed air inlet 131 to which the compressed air tube 141 is connected is actually compressed air provided at the upper end of a rotatable connecting pipe 133 provided in the drilling machine main body 130. The introduced compressed air is provided in the receiving portion 133a and flows into the tube of the drilling rod 150 from the connecting portion 133b at the lower end through the connecting tube 133. The compressed air that has flowed into the drilling rod 150 is further ejected from the tip, and plays the role of blowing away the crushed rock.
The oil introduced from the hydraulic tube 142 through the hydraulic inlet 132 into the drilling machine main body 130 rotates the hydraulic gear 135 provided in the drilling machine main body 130. The hydraulic gear 135 is configured to be screwed with a driven gear 134 that is fixed to the connecting pipe 133. Therefore, when the hydraulic gear 135 is rotated, the connecting pipe 133 is rotated via the driven gear 134, the drilling rod 150 is rotated, the drilling bit 151 is rotated, and the rock is drilled.

Referring also to FIG. 12, the self-propelling means for self-propelling the slide table 120 includes a guide chain 160, a hydraulic motor 170, a drive gear 180 and auxiliary wheels 181 and 182 thereof.
The guide chain 160 is provided in the longitudinal direction along the center of the guide tower 110 and is stretched from the vicinity of the upper end of the guide tower 110 to the vicinity of the lower end thereof.
The hydraulic motor 170 is attached to the slide table 120 and moves together with the slide table 120. A hydraulic tube 171 is detachably attached to the hydraulic motor 170 from the outside, and the hydraulic motor 170 is driven by introducing oil.
The drive gear 180 is provided on the slide table 120, and rotates by receiving the rotation of the hydraulic motor 170 through or without a reduction gear.
The driving gear 180 is provided in mesh with the guide chain 160. As a result, the drive gear 180 rotates, and the slide table 120 travels on the guide chain 160 together with the drive gear 180. The direction of self-running can be changed by changing the direction of supply of hydraulic oil to the hydraulic motor 170 or switching the rotation direction by interposing an intermediate gear or the like between the hydraulic motor 170 and the drive gear 180. . Of course, in the case where a forcing force is not applied in the drilling direction of the drilling rod 150, the drive gear 180 may be driven to rotate only in the direction in which the drilling rod 150 is raised. It is enough.
The pair of auxiliary wheels 181 and 182 prevent the drive gear 180 from being detached from the guide chain 160 and are attached to the slide table 120.
In addition, when the hydraulic motor 170 is configured so that a forcing force in the drilling direction can be applied to the drilling rod 150, the rotation of the hydraulic motor 170 is performed so that the load due to the forcing force does not increase beyond a certain level. The driving force is made to diverge due to slip or the like in the middle.

  Since the guide chain 160 is only stretched from the vicinity of the upper end to the vicinity of the lower end along the center of the guide tower 110 as a single line, the wiring of the guide chain 160 becomes very simple, and in the configuration of the drilling device 100 The guide chain 160 does not need to be stretched around the guide tower 110, and it is not necessary to extend and attach a guide metal fitting for circulating the guide chain 160 from the guide tower 110, so that they can be handled and moved. It is possible to obtain the merit that it is difficult to cause troubles and damages.

In the drilling operation by the drilling device 100, the drill bit 151 at the tip of the drill rod 150 is brought into contact with the ground in a state where the guide tower 110 is set up in a vertical direction at a predetermined position on the slope S. The operation is started by turning on an oil introduction switch (not shown) by the hydraulic tube 142 and turning on a compressed air introduction switch (not shown) by the compressed air tube 141. The hydraulic oil introduced into the drilling machine main body 130 rotates the hydraulic gear 135, thereby rotating the connecting pipe 133 and rotationally driving the drilling bit 150. As a result, the drilling bit 151 at the tip makes a hole in the ground. According to the drilling, the drilling machine main body 130 descends by its own weight together with the slide table 120. The compressed air introduced into the drilling machine main body 130 enters the inner hole of the drilling rod 150 through the connecting pipe 133 and is ejected from the tip. As a result, rock powder or the like that has been drilled is removed from the drilling position.
When the drilling operation is completed, the operator turns on an oil introduction switch (not shown) from the hydraulic tube 171 to the hydraulic motor 170, so that the slide table 120 self-runs and moves up with the drilling machine main body 130. The operation stops automatically when it reaches the uppermost position (initial position). Regarding the automatic stop, a limit switch (not shown) may be operated when the drilling machine main body 130 is raised to a predetermined uppermost position (initial position).

  In the self-running means, the hydraulic motor 170 is used, but another motor such as an electric motor may be used. In addition, the drive gear 180 and the guide chain 160 can be moved so as to mesh with each other. However, as long as the slide table 120 can be self-propelled from the vicinity of the upper end to the vicinity of the lower end along the guide tower 110, a method other than the meshing method is possible. It may be.
