[0030] A push rod 4 is installed on one side of the blasting charge box 1 to facilitate the operator to push the device. A charge groove 2 is formed on the other side of the blasting charge box 1 to install the charge assembly. A plurality of buffer assemblies are installed between the bottom of the blasting charge box 1 and the top of the base 11. The buffer assembly includes a movable seat 13 and a damping rod 15. The movable seat 13 is installed on the top of the base 11, and the damping rod 15 is installed on the bottom of the blasting charge box 1. The positions of the movable seat 13 and the damping rod 15 correspond to each other. The free end of the damping rod 15 is movably inserted into the top of the movable seat 13 after being sleeved with a second spring 16. At the same time, a limiting plate 19 is installed at a suitable position, and a second damping rod 18 is movably inserted into the limiting plate 19. A limiting head is installed at one end of the second damping rod 18, and the other end of the second damping rod 18 is connected to a first damping rod 17. The other end of the first damping rod 17 is hingedly connected to the bottom of the blasting charge box 1, and a first spring 14 is sleeved on the second damping rod 18. When the blasting charge box 1 is jolted during transportation, the blasting charge box 1 drives the damping rod 15 to move inside the movable seat 13, and the bottom of the first damping rod 17 is pressed to drive the second damping rod 18 to move inside the limiting plate 19. Under the action of the second spring 16 and the first spring 14, the force acting on the blasting charge box 1 can be absorbed and weakened, so as to buffer and protect the explosive tube 3 in the charge groove 2, avoid damaging the explosive tube 3 in the charge groove 2 during jolting, and affect the use effect, and ensure the transportation effect.

[0031] A guide block 21 is installed on the bottom of both sides of the blasting charge box 1, and a guide groove 20 is accurately formed on the inner side of the limiting seat 31 corresponding to the position of the guide block 21.

[0032] The pull plate 27 of the charge assembly and the charge groove 2 are installed in a drawer type. A sliding block 32 is installed at the bottom of the installation section of the pull plate 27, and a sliding groove 33 is formed in the charge groove 2 corresponding to the movement direction of the sliding block 32. The sliding block 32 is movably installed in the sliding groove 33, and a first magnet 8 is installed on the inner side of the sliding groove 33 and the sliding block 32. A second magnet 10 is installed on the sliding block 32 corresponding to the position of the first magnet 8. A plug ring 24 is installed on the side wall of the pull plate 27, and a bolt 25 is movably installed on the side wall of the blasting charge box 1.

A fixed plate 5 of the clamping assembly is installed on the top surface of the installation section of the pull plate 27. A receiving groove 6 is formed in the length direction of the installation section of the pull plate 27. A threaded rod 7 is rotatably arranged in the receiving groove 6 through a bearing. One end of the threaded rod 7 penetrates through the pull plate 27 and is connected to a knob 22. A threaded sleeve 9 is installed at the bottom of a movable plate 30 and is fitted on the threaded rod 7. Anti-skid pads 28 are installed on the opposite sides of the fixed plate 5 and the movable plate 30, and a plurality of anti-skid protrusions 29 are uniformly arranged on the inner side of the anti-skid pads 28.

[0033] When the charging operation is needed, the operator holds the handle 23, pulls out the pull plate 27 from the charging groove 2, rotates the knob 22 according to the diameter of the explosive tube 3, adjusts the distance between the movable plate 30 and the fixed plate 5, places the explosive tube 3 between the fixed plate 5 and the movable plate 30, rotates the knob 22 again to make the movable plate 30 tightly clamp the explosive tube 3, avoids the shaking of the explosive tube 3 during transportation, and causes the phenomenon of explosive sliding off. Then the pull plate 27 is pushed into the charging groove 2, at this time the first magnet 8 and the second magnet 10 are attracted to each other, the pull plate 27 is preliminarily fixed, and then the bolt 25 is inserted into the insertion ring 24 to further fix the pull plate 27.

[0034] When the device needs to be transported, the operator pushes the push rod 4 to move the device to the designated place. During transportation, if the bumpy road is encountered, the buffer assembly starts to work. The second spring 16 and the first spring 14 will be elastically deformed according to the vibration condition, absorb the vibration energy, and the damping rod 15, the first damping rod 17 and the second damping rod 18 will work together to buffer and stabilize the blasting charging box 1, so as to ensure that the explosive is not damaged during transportation. After reaching the blasting operation point, the operator pulls out the bolt 25, pulls open the pull plate 27, and reversely rotates the knob 22 to cancel the clamping and fixing of the explosive tube 3 between the fixed plate 5 and the movable plate 30, so that the explosive can be taken out for blasting operation. It is simple to operate, convenient to use, improves the flexibility and convenience of the device.

[0035] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
