[0019] Reference Figures 7-9As shown, the upper surface of the placement plate 41 is provided with a storage device 7, which includes a storage box 71 located directly above the placement plate 41, and is used for storing a plurality of firecracker rods. The direct layout design ensures the maximum utilization of the storage space and facilitates the quick placement and removal of firecracker rods by the staff, improving the operation convenience. The storage box 71, as the core storage component, can concentrate the storage of a plurality of firecracker rods. The inner surface of the storage box 71 is threadedly connected with three stop pins 72 for limiting the position of the firecracker rods. The distributed layout of the three stop pins 72 can limit the firecracker rods from multiple points to ensure that the firecracker rods remain in an orderly arrangement state in the storage box 71, effectively limiting the displacement of the firecracker rods. The two sides of the storage box 71 are fixedly connected with limiting blocks 73, and the limiting blocks 73 and the inner wall of the placement plate 41 are threadedly connected with two limiting pins 74. The two limiting blocks 73 are symmetrically designed to cooperate with the two limiting pins 74 to be fixed, forming a stable double fixing structure, which can firmly lock the storage box 71 on the placement plate 41 to prevent the storage box 71 from shifting during equipment transportation or vibration, ensuring the installation stability.

The plug-in structure design makes the opening and closing operation of the sealing plate 75 simple and efficient, and the staff can quickly complete the switching action without the aid of tools, improving the work efficiency. The sealing plate 75 can effectively prevent dust, water vapor and other impurities from entering the inside of the storage box 71. The two sides of the storage box 71 are fixedly connected with fixed strips 76, and the surface of the fixed strips 76 is fixedly connected with elastic ropes 77. The elastic ropes 77 are inserted into the inner surface of the sealing plate 75. The surface of the sealing plate 75 is provided with two clamping grooves 78, and the elastic ropes 77 are inserted into the inner surface of the clamping grooves 78 of the sealing plate 75. The fixed strips 76 provide a stable installation carrier for the elastic ropes 77.

The cooperation of the double clamping grooves 78 and the elastic ropes 77 further improves the locking stability, and the elastic structure has a certain buffering property.
[0020] The working principle of the present application is as follows: open the sealing plate 75 on the storage box 71 to unlock by pulling the elastic rope 77 out of the clamping groove 78 of the sealing plate 75, and put a plurality of firecracker rods into the storage box 71. The three stop pins 72 in the storage box 71 limit the firecracker rods from multiple points. After closing the sealing plate 75, the elastic rope 77 is clamped into the clamping groove 78 by means of its own elastic tension, forming a reliable lock to isolate dust and water vapor from the outside. The storage box 71 is firmly fixed on the placement plate 41 by the cooperation of the two limiting blocks 73 and the double limiting pins 74, avoiding displacement in subsequent operations. When the powder stick is used, the storage plate 52 is placed on the placement plate 41, and then the limiting pin 74 is rotated to the limiting block 73 and the inner wall of the placement plate 41, so as to fix the storage box 71 on the placement plate 41, and then the blocking pin 72 is turned out from the storage box 71, and the powder stick in the storage box 71 falls to the inner surface of the placement plate 41; the device is started through the control part 2 of the vehicle body 1, and the control part 2 drives the hydraulic rock drill 3 to start the rock drilling operation. The hydraulic rock drill 3 is used as a rock drilling core component, and directly acts on the operation surface to complete the drilling process; The vibration generated in the rock drilling process is conducted to the propelling device 4 through the hydraulic rock drill 3, and at this time the damping device 5 starts the active damping action. The vibration force is first transmitted to the supporting plate 51 fixedly connected with the hydraulic rock drill 3, and the supporting plate 51 and the sleeving structure of the storage plate 52 form preliminary displacement buffering to reduce the rigid impact; then the multiple distributed elastic strips 53 between the connecting plate 54 and the storage plate 52 uniformly disperse the force and absorb the vibration energy through elastic deformation, so as to avoid local stress concentration; at the same time, the main spring 57 on the fixed plate 56 at the upper and lower ends of the storage plate 52 forms double elastic buffering with the elastic strip 53, which weakens the vibration of different frequencies in layers, greatly reduces the influence of the vibration on the propelling device 4, and prevents the loosening of parts or the positioning deviation of the powder stick; After the rock drilling is completed, the control part 2 is switched to the propelling mode, the motor 45 of the propelling device 4 is started, the power of the motor 45 is transmitted to the lead screw 42 after speed regulation by the gear box 46, and the gear box 46 buffers the power impact of the motor 45 at the same time to protect the transmission components; when the lead screw 42 rotates, the moving block 43 slides along the inner surface of the placement plate 41, and the moving block 43 slides on the surface of the supporting rod 47 through the sliding hole 48 when moving, so as to prevent sliding deflection, and the push head 44 on the side wall of the moving block 43 pushes the powder stick in the placement plate 41 to the drill hole; When the push head 44 retracts, the push head 44 drives the top column 61 and the sliding block 62 to slide, the sliding block 62 drives the auxiliary spring 64 on the top block 63 to stretch, and when the push head 44 pushes the powder stick to move, the auxiliary spring 64 retracts, the auxiliary spring 64 drives the top column 61 to move, the top column 61 moves to the bottom end of the other powder stick, so as to avoid that the upper powder stick is stuck in the placement plate 41 when the powder stick in the placement plate 41 moves, and to ensure the continuous and smooth propelling process, before the lead screw 42 is used, the protective cover 65 is fixed on the placement plate 41 through the positioning pin 66, and when the lead screw 42 rotates, the lead screw 42 rotates on the inner surface of the protective cover 65, and the protective cover 65 can protect the lead screw 42.
