[0008] The inner top of the shell is fixedly connected with a hydraulic motor, the output end of the hydraulic motor is fixedly connected with a rotating shaft, and the side of the rotating shaft away from the hydraulic motor is fixedly connected with a rotating shaft.
[0009] By adopting the above technical scheme, the hydraulic motor can drive the rotating shaft to rotate, and then drive the rotating shaft to rotate.
[0010] As a further description of the above technical scheme:
[0011] The side wall of the hydraulic motor is fixedly connected with an inlet, and the side wall of the hydraulic motor is fixedly connected with an outlet, and the outlet is located below the inlet.

The connecting shaft can be connected to an external lifting mechanism to further control the downward movement of the shell.
[0028] Through the above technical solutions, the novel pebble layer drilling and hammering integrated machine has at least the following beneficial effects:
[0029] Compared with the prior art, the novel pebble layer drilling and hammering integrated machine comprises a hydraulic motor, a rotating shaft, a rotating shaft, a second limiting block, a limiting groove, a shell, a counterweight, a roller, a moving groove, a drill bit, a first limiting block and a spring. When drilling is needed, the hydraulic motor works to drive the rotating shaft to rotate, thereby driving the rotating shaft to rotate. Since the second limiting block is located inside the limiting groove and the shell does not rotate, the second limiting block, the counterweight and the roller will not rotate with the rotation of the rotating shaft. Since the roller is located in the moving groove, the rotation of the rotating shaft will drive the roller to first rise along the inclined groove part of the moving groove. When the roller rises to the intersection part of the vertical groove and the inclined groove, the roller will free fall along the vertical groove due to the gravity of the counterweight, thereby the counterweight generates a great impact on the drill bit, that is, hammering is generated. At the same time, due to the existence of the first limiting block and the spring, the drill bit can be reset in time even after being impacted and moving downward, so that the integrated machine can hammer while drilling. Compared with the existing drilling machine, which simply relies on the rotation of the drill bit for cutting, it is difficult to effectively break large-diameter pebbles. The drill bit is easy to slip on the surface of the pebble, cannot penetrate into the stratum, and results in slow drilling speed and long time consumption. The novel pebble layer drilling and hammering integrated machine hammers the pebble layer while drilling, breaks or loosens the pebble, and forms a synergistic effect with the rotation of the drill bit for cutting, thereby effectively improving the breaking efficiency, speeding up the drilling speed, and shortening the construction period.
