The outer side of the fixed ring block is rotatably connected to a rotating block. The fixed ring block can limit and connect the rotating block, so that the rotating block can be used smoothly and is not easy to fall off during rotation. The auxiliary mechanism can reinforce and assist the support mechanism, so that the support mechanism is more effective when in use and the main board is more stable when in use. The lifting mechanism can be used to drive the drilling machine body to move up and down, so that the drilling machine body can smoothly drill holes in the mine. At the same time, the drilling machine body can move up and down freely.

[0004] However, when blasting inside a mine, it is usually done by making holes in the side wall to allow the blasting direction to gradually advance forward or toward the target direction. The aforementioned document does not allow for effective hole making in the wall, and the ground inside the mine is not stable, requiring greater stability when drilling holes. Utility Model Content

An extension frame is installed inside each of the two upper sleeves, and an assembly frame is installed between the two upper sleeves. A drilling machine is installed on the assembly frame, and two adjusting rods are installed at the lower end of the support frame.

[0008] Furthermore, the extension frame is provided with a plurality of threaded holes evenly distributed thereon, and the extension frame is slidably connected to the inner wall of the upper sleeve.

[0009] Furthermore, the lower end of the assembly frame is provided with a mounting bracket, and the middle part of the support frame is provided with a mounting hole that is adapted to the mounting bracket.

[0010] Furthermore, a drilling machine is slidably connected to the inner side of the assembly frame.

[0011] Furthermore, the drilling machine includes a fixed frame and a drive motor installed inside the fixed frame. A drill bit is installed at the output end of the drive motor, and a push rod is provided on the outer wall of the fixed frame.

[0012] Furthermore, a sliding groove is provided on one side wall of the assembly frame, and a scale mark is provided on the outside of the sliding groove.

[0013] Furthermore, the adjusting rod includes a threaded sleeve welded to the lower end of the support frame, the inner wall of the threaded sleeve being threaded with a threaded post, and the lower end of the threaded post being fixed with several anti-slip pins.

[0014] Furthermore, the sidewalls of the support frame are connected to support legs via swivel joints.

[0015] Furthermore, the support leg includes a movable sleeve with threads on its inner wall and a threaded rod disposed inside the movable sleeve.

[0016] Furthermore, the lower end of the threaded rod is rotatably connected to a movable plate, and the movable plate has a fixing hole.

[0017] The beneficial technical effects of this utility model are as follows: According to the drilling device for blasting in mining engineering of this utility model, the upper sleeve above the support frame, in conjunction with the extension frame, supports the upper end of the mine shaft. To prevent unevenness of the ground or top, the extension frame's extension degree can be adjusted with bolts. The bottom can also be finely adjusted with an adjusting rod to ensure effective support and improve stability. Then, by rotating the support legs to a suitable angle, the threaded rod is gradually rotated out to press against the ground. A movable plate, in conjunction with a fixing bolt, is driven into the ground to further enhance stability and prevent shaking during drilling. The height of the assembly frame is adjusted according to the drilling height and fixed with bolts. During drilling, the drilling machine is pushed forward to contact the side wall for drilling operations.
