Therein, as shown in fig. 3, a drill is used for drilling a hole in a rock mass and placing a rock bolt 10, comprising a feed beam 1, a rock bolt clamping assembly 2, a rock bolt storage 3, a power head 4, a first driver 5 and a drill rod holder 12. The feed beam 1 can be rotated to adjust the position to be constructed, and the drill rod can be drilled in the rock mass at each position. The power head 4 is the power equipment of the rock drill and is slidably mounted on the feed beam 1 to push the drill rod for drilling holes in the rock mass.

The controller may be, for example, a PLC controller.
The parameter setting device is electrically connected with the controller and is used for setting the actions of the power parts of the drilling machine and the grouting device, for example, the advancing speed of the power head 4, the speed of the power head 4 driving the drill rod to rotate, the grouting pressure of the grouting device and the like can be set through the parameter setting device.
In summary, through the technical scheme provided by the disclosure, the drilling, installation and grouting processes of the jumbolter are controlled by the controller, and after the actions of all the parts are set in the parameter setting device, the controller drives all the power parts to work. The drilling machine is integrated with an anchor rod mounting device, after the drilling machine finishes drilling work, the anchor rod clamping assembly 2 can clamp the anchor rod 10 of the anchor rod storage part 3 to place the anchor rod 10 at the front end of the power head 4, and then thrust of the power head 4 is utilized to push the anchor rod 10 to enter an anchor rod hole. The manual working procedures can be reduced in the process, the automation degree is improved, and therefore the problems of long construction period and low construction efficiency in the operation process of the jumbolter can be solved.

In the construction process, the distances between the fixed part 201, the movable part 202 and the first driving cylinder 203 and the push beam 1 and the anchor rod storage part 3 can be adjusted by rotating the rod 7, so that the clamping station can be accurately reached during clamping operation, and the work of other parts can be prevented from being interfered during non-clamping operation. Further, the first driving cylinder 203 and the second driving cylinder 1203 and the third driving cylinder 604 described below may be hydraulic cylinders or air cylinders, which the present disclosure is not limited to.
