[0003] However, it still has some shortcomings. For example, in tunnel blasting operations, the accuracy of the charging depth directly affects the blasting effect. The traditional PVC pipe charging method relies entirely on the worker to push the PVC pipe into the drill hole to set the position of the explosives, which can easily lead to inaccurate control of the depth of the explosive placement, thereby affecting the blasting effect. Although the traditional PVC pipe charging method improves efficiency, it has the safety risk of static electricity accumulation and cannot detect the depth and inclination angle of the drill hole.

[0004] In order to solve the above problems, the present application proposes a wooden blasting stick charging device for tunnel blasting. Utility Model Content

[0008] Preferably, a sensing device is fixedly mounted on the inner surface of the front end of the telescopic stick.

[0009] Preferably, a measuring device is fixedly mounted on the outer wall of the main gun barrel.

[0010] Preferably, a display system is fixedly mounted on the outer wall of the measuring device.

[0011] Preferably, an infrared emitter is fixedly mounted on the outer wall of the measuring device.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model presses the fixed button inward to disengage it from the corresponding limiting hole, so that the telescopic stick can be pushed toward the inner wall of the main gun barrel, and the fixed button is embedded in the corresponding limiting hole for fixation, so that the length of the gun stick can be set, and the set gun stick is used to push the explosive bag from the drill hole. After each loading is completed, the length of the gun stick is set so that the interval between the explosive bags is equal to the shortened length of the wooden gun stick, so that the depth of the explosive placement can be accurately controlled by setting the length of the wooden gun stick, thereby effectively ensuring the blasting effect of the tunnel.

[0014] The utility model can effectively prevent current leakage and static electricity generation by coating the metal parts inside the wooden gun stick charging equipment with insulating paint, and the outermost main gun barrel and telescopic stick are made of hardwood material, which is not easy to generate static electricity, reducing the risk of detonation.

Finally, the detection result is displayed by using a display system. BRIEF DESCRIPTION OF THE DRAWINGS
