[0002] Bench blasting, also known as stepped blasting, is a process of using the explosive energy to break ore and rock, forming a stepped shape of ore and rock loosening and destruction. This blasting method is widely used in open-pit mining, highway and railway construction, water conservancy and hydropower projects, etc. When implementing bench blasting, multiple influencing factors need to be considered to ensure the blasting effect and safety.

[0035] The working principle of the present utility model is as follows: The staff moves the support box 1 to align the insertion rod 27 with the already drilled blasting hole, and then starts the hydraulic rod 26 through an external controller. The hydraulic rod 26 drives the insertion rod 27 to insert into the blasting hole for measurement with the current blasting hole as the center; then rotates the support box 1 with the insertion rod 27 as the axis center to align it with the planned horizontal line of the blasting hole;

[0036] Then start the drive motor 9. The drive motor 9 cooperates with the threaded rod 10 to drive the threaded sleeve 11 to move. The threaded sleeve 11 cooperates with the moving plate 19 to drive the third movable shaft 20 to move. The third movable shaft 20 drives the second adjusting frame 8 to move. The second adjusting frame 8 and the first adjusting frame 7 cooperate to drive the second movable shaft 18 to slide inside the movable frame 16, and use the second movable shaft 18 to push the movable frame 16. While the movable frame 16 moves, it drives the liquid storage tank 12, the traction wheel 24, and the light-emitting component of the laser rangefinder 4 to move. While the traction wheel 24 moves, it pulls out the tape measure 23 and compresses the clockwork spring 22. The staff determines the measurement distance by observing the scales on the surface of the tape measure 23 and conducts a secondary detection through the data fed back by the laser rangefinder 4 to the control terminal, which can effectively improve the accuracy of the measurement data;

[0037] When the liquid storage tank 12 moves to the position of the next group of blasting holes, the solenoid valve 15 can be started. The solenoid valve 15 opens the drain pipe 14 to drip the marking pigment in the liquid storage tank 12, realizing the function of automatic marking and effectively improving the construction efficiency.
