The surface of the rectangular plate 403 is respectively provided with longitudinal threaded holes threadedly connected to the outer surfaces of the longitudinal threaded columns 407, and longitudinal holes slidably connected to the outer surfaces of the two fixing rods 408.

[0052] Specifically, the longitudinal position of the rectangular plate 403 can be adjusted during the rotation of the longitudinal threaded column 407 .

[0053] Among them, the present invention sets a driving component 400, so that after the blasting tube 200 is fixed, the device can move the bottom plate 401 to make it close to the barrel, and start the driving motor 406 and the second hydraulic rod 404 respectively. The rotation of the driving motor 406 drives the longitudinal threaded column 407 to rotate, and the rotation of the longitudinal threaded column 407 drives the rectangular plate 403 to move longitudinally, thereby realizing the adjustment of the longitudinal position of the semicircular charging tube 301.

The rotation of the transverse threaded column 104 drives the leftmost slider 102 to move to the left under the action of the internal threaded sleeve 105. When the slider 102 moves, it can drive the other sliders 102 except the rightmost slider 102 to move synchronously under the action of the linkage component 106, so as to realize the synchronization of two adjacent sliders 102. The spacing between the sliders 102 is adjusted synchronously, thereby realizing the adjustment of the air spacing between the plurality of blasting tubes 200 on the plurality of placement seats 103, thereby ensuring the blasting effect; after the spacing between the blasting tubes 200 is adjusted, the first hydraulic rod 303 can be activated to contract, driving the semicircular charge tube 301 to move downward, so that the two arc-shaped clamping plates 302 inside the semicircular charge tube 301 are located on both sides of the blasting tube 200, and then the rotating block 3010 is rotated to drive the rotating rod 309 to rotate, and the rotation of the rotating rod 309 is The two-way screw 307 is driven to rotate under the action of the bevel gear 3011, and the rotation of the two-way screw 307 drives the two moving plates 306 to move toward the middle at the same time, thereby driving the two arc clamping plates 302 to move toward the middle at the same time, and clamping a plurality of blasting tubes 200 at the same time. After that, the first hydraulic rod 303 is started again to extend, driving the semicircular charging tube 301 to lift, so that the blasting tube 200 is separated from the concave placement groove 108; after fixing the blasting tube 200, the device can move the bottom plate 401 to make it close to the barrel, and The driving motor 406 and the second hydraulic rod 404 are started respectively. The rotation of the driving motor 406 drives the longitudinal threaded column 407 to rotate. The rotation of the longitudinal threaded column 407 drives the rectangular plate 403 to move longitudinally, thereby adjusting the longitudinal position of the semicircular charge tube 301. At the same time, the extension and retraction of the second hydraulic rod 404 can adjust the height of the semicircular charge tube 301, so that the semicircular charge tube 301 can be adjusted to a position height corresponding to the barrel, so that the semicircular charge tube 301 can smoothly enter the interior of the barrel.
