DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on its embodiments with reference to the drawings. FIG. 1 is a front view of an embodiment of an anchor drill supply device 1 of the present invention. The cart 1a has wheels 2 and is configured to be movable. The arm 3 is configured such that one end 4 on the carriage 1a rotates about a vertical axis 5 and a parallel axis 6 with respect to the carriage 1a as an axis, and the arm 3 can be expanded and contracted by a cylinder 3a. The motor 3b having a reduction mechanism causes the arm 3 to move the vertical axis 5 and the parallel axis 6
Although it is rotated with the axis as the axis, when the vertical axis 5 is used as the axis, the rotation may be performed manually. The gripper 7 is rotatable about a shaft center 8 of the arm 3 by a cylinder 8a and bevel gears 8b and 8c, and
Two axial cores 10 and 11 that are perpendicular to the axial center 8 of the arm 3 near the other end 9 of the arm 3 and are also perpendicular to each other,
A tubular anchor drill 12 that is rotatably provided at the center by cylinders 10a and 11a and is used to pierce the ground.
Clamping hand 16 by cylinder 7a so as to clamp
17 is configured to be openable and closable.

FIG. 2 is a plan view of another embodiment of the anchor drill supply device 1 of the present invention. The embodiment of FIG. 1 is
Most of the configurations are common, except that one end 4 of the arm 3 on the carriage 1a rotates about only the vertical axis 5 with respect to the carriage 1a.

Opening and closing around a nut 31 with a nut 32 at the other end
And so on. When the handle 33 is manually rotated, the nut 32 and the clip 34 are interlocked and rotated. Here, when the handle 33 is tilted sideways, the clip 34 passes through the hole of the member 35 due to the urging force of the spring 36, is separated from the member 35, and the pair of outer tube clamps 22 is opened. By the reverse operation,
The pair of outer tube clamps 22 are in a closed state and hold the outer tube 19 therebetween. It is also possible to separate the pair of outer tube clamps 22 from each other by removing the split pin 30 from the nut 31 and then removing the nut 31. The pair of inner pipe clamps 23 are opened and closed around a nut 38 having a split pin 37, and the other end is closed by a nut 40 or the like. When the handle (not shown) is manually rotated, the nut 40 and the clip 40a are interlocked and rotated. Here, when the handle is tilted to the side, the clip 40a passes through the hole of the member 39 by the urging force of the spring 41 and is separated from the member 39, and the pair of inner pipe clamps 23
However, the pair of inner pipe clamps 23 is closed and the inner pipe 20 is clamped by the reverse operation.
The pair of inner pipe clamps 23 can be separated from each other by removing the split pin 37 from the nut 38 and further removing the nut 38.

Next, the anchor drill storage device 24 is
As shown in FIGS. 3 and 4, together with the anchor drill supply device 1, it is detachably connected by a connector 24a,
Alternatively, as shown in FIG. 1 and FIG. 2, the anchor drills 12 are placed independently, and a plurality of anchor drills 12 are placed side by side on the placing table 25 and stored. Next, the anchor drill storage device 24
As shown in FIGS. 3 and 4, the anchor drill 12
Are separated by a flat plate 27 and stacked in a plurality of stages, and placed on the mounting table 25. The mounting table 25 is mounted on the cylinder 26 and the support 26a.
It is possible to move up and down by tilting the mounting table 25 slightly,
