The inclined plate 10 is slidably fitted to the bottom end of the arc-shaped slag discharge plate 9.

[0024] A positioning mechanism is connected between the outer wall of the inclined plate member 10 and the transverse plate member 6 .

[0025] refer to Figure 1 and Figure 2As shown, the positioning mechanism includes a secondary electric telescopic rod 11, a circular ring 12, a return spring 13 and an outer cylinder 14. The secondary electric telescopic rod 11 is symmetrically connected to the bottom end of the horizontal plate 6.

The outer cylinder 14 is sleeved and connected to the outer wall of the inclined plate 10, and the top surface of the outer cylinder 14 is connected to the return spring 13. When the secondary electric telescopic rod 11 is turned on, the outer cylinder 14 drives the slag discharge mechanism to descend. After the bottom surface of the outer cylinder 14 contacts the ground, the return spring 13 between the circular ring 12 and the outer cylinder 14 will be subjected to a certain extrusion force. The return spring 13 will apply part of the extrusion force to the outer cylinder 14, so that the outer cylinder 14 is more stably attached to the ground.

The mounting plate 18 is connected to the top right side of the inner wall of the outer cylinder 14, and the secondary drive motor 19 is fixedly connected to the left side of the top of the mounting plate 18 by a positioning bolt.

[0031] Working principle: Before drilling, turn on the secondary electric telescopic rod 11, so that the outer cylinder 14 drives the slag discharge mechanism to descend. After the bottom surface of the outer cylinder 14 contacts the ground, the return spring 13 between the ring 12 and the outer cylinder 14 will be subjected to a certain extrusion force. The return spring 13 will exert part of the extrusion force on the outer cylinder 14, so that the outer cylinder 14 fits more stably on the ground. The primary electric telescopic rod 2 is started, and the primary drive motor 3 drives the drill rod 4 to descend. The setting of the circular opening 7 ensures that the horizontal plate 6 will not affect the descent of the drill rod 4. At the same time, turn on the primary drive motor 3, so that the drill rod 4 drills the ground.

[0032] When drilling, the secondary drive motor 19 is turned on and the drive gear 20 is rotated. With the cooperation of the teeth 21, the rotating cylinder 8 drives the arc-shaped slag discharge plate 9 to rotate. The rock and soil debris drilled out by the drill rod 4 will fall onto the inclined surface of the inclined plate 10. When the arc-shaped slag discharge plate 9 rotates, it pushes the rock and soil debris to rotate. Under the action of centrifugal force, the rock and soil debris enters the connecting groove 15 and enters the slag collecting cover 16, and is collected by the slag collecting cover 16.
