[0055] Through the above technical solution, the mobile driving component 5 can automatically drive the blasting tube to move and insert into the blast hole. At the same time, when the blasting tube encounters foreign objects blocking it during insertion, the protection stop function can be realized, thereby avoiding damage caused by obstacles due to excessive force during insertion. Furthermore, in order to solve the problem in the prior art that ordinary blasting tube fixing equipment is prone to bursting out due to recoil force when the blasting tube is blasting, the present application has designed an anti-bounce component 7. The anti-bounce component 7 can automatically limit the blasting tube that bursts out during blasting, and automatically perform auxiliary fixation. No additional power source is required for auxiliary fixation, thereby effectively avoiding the phenomenon of bursting out during blasting.

[0056] For further technical solutions, see Figure 2 As shown, the core driving structure 2 includes a rotating ring 201, a guide groove 202, an arc-shaped rack 203, a servo motor 204 and a gear 205. The rotating ring 201 is arranged on the arc surface of the fixed sleeve 1 and is rotatably connected to the fixed sleeve 1. A plurality of guide grooves 202 are opened on the side wall of the rotating ring 201.

[0057] An arc-shaped rack 203 is fixedly connected to the outer wall of the rotating ring 201, and the servo motor 204 is fixedly arranged on the outer wall of the fixed sleeve 1. A gear 205 is fixedly connected to the end of the output shaft of the servo motor 204, and the gear 205 and the arc-shaped rack 203 are meshed with each other. Through the present technical solution, the operation of the servo motor 204 can drive the gear 205 to rotate, and the rotation of the gear 205 can drive the arc-shaped rack 203 to rotate, thereby driving the rotating ring 201 to rotate, thereby realizing the rotation function of the rotating ring 201.

[0058] For specific technical solutions, please refer to Figure 3 and Figure 4As shown, the blasting tube fixing assembly 4 includes a movable sleeve A401, a movable rod A402, a U-shaped frame A403, a guide wheel 404, a tripod A405, a circular guide rod A406, a support arm 407 and a fixing claw 408. The movable sleeve A401 is provided with a plurality of them, and the plurality of movable sleeves A401 all penetrate the fixed sleeve 1 and slide with the fixed sleeve 1. The movable rod A402 is slidably connected in the inner cavity of the movable sleeve A401, one end of the movable rod A402 is fixedly connected to one end of a spring 409, and the other end of the spring 409 is fixedly connected to the inner cavity wall of the movable sleeve A401, and the other end of the movable rod A402 is fixedly connected to the U-shaped frame A403, and the U-shaped frame A403 is fixedly connected to the inner cavity wall of the movable sleeve A401. A guide wheel 404 is rotatably connected, and a tripod A405 is fixedly connected to one end of the movable sleeve A401, and a circular guide rod A406 is fixedly connected to the tripod A405, and the circular guide rod A406 extends to the guide groove 202 and slides with the guide groove 202. According to the technical solution, the rotation of the rotating ring 201 can drive the guide groove 202 to rotate and move, so that the rotation of the guide groove 202 can drive the circular guide rod A406 to move, thereby driving the movable sleeve A401 to move, realizing the synchronous centering movement function of the movable sleeve A401, thereby driving the guide wheel 404 to move in the centering manner, and the guide wheel 404 contacts the outer wall of the blasting tube, so that the blasting tube is limited and guided;

[0059] The movable sleeve A401 is fixedly connected with support arms 407 on both sides of the arc-shaped wall, and a fixing claw 408 is rotatably connected with one end of the support arm 407. Through the technical solution, when the blasting tube needs to be fixed, the rotating ring 201 can continue to rotate, and the continued rotation of the rotating ring 201 can drive the movable sleeve A401 to continue to move toward the center, thereby driving the support arm 407 to move, so that the fixing claw 408 moves and contacts the outer wall of the blasting tube, so that the fixing claw 408 is pressed against the outer wall of the blasting tube, and the blasting tube is clamped and fixed. Through the centering clamping of multiple fixing claws 408, the blasting tube can be fixed. The blasting tube is fully and effectively limited and fixed, thereby realizing the function of automatic fixing. It can be seen from the above description that the rotation of the rotating ring 201 can drive the movable sleeve A401 to move inwardly toward the center, and the movement of the movable sleeve A401 can drive the guide wheel 404 to move. When the guide wheel 404 contacts the outer wall of the blasting tube and the fixed claw 408 has not yet contacted the blasting tube, it can play the role of limiting and guiding the blasting tube, so as to facilitate the insertion of the blasting tube into the blasthole. After the blasting tube is inserted into the blasthole, the movable sleeve A401 continues to move, so that the fixed claw 408 can be pressed against the outer wall of the blasting tube, thereby playing the role of automatic fixing.

[0060] As a preferred technical solution, please refer to Figure 5 , Figure 6 and Figure 7 As shown, the mobile drive assembly 5 includes a mobile sleeve B501, a mobile rod B502, a tripod B503, a circular guide rod B504, a U-shaped frame B505, a driving wheel unit 506 and a motor 507. The mobile sleeve B501 is provided with a plurality of them, and the plurality of mobile sleeves B501 are equidistantly arranged on the fixed sleeve 1. The mobile sleeve B501 penetrates the fixed sleeve 1 and slides with the fixed sleeve 1. The tripod B503 is fixedly connected to one end of the mobile sleeve B501, and the tripod B503 is fixedly connected to the circular guide rod B504. One end of the circular guide rod B504 extends to the guide groove 202 and slides with the guide groove 202. Through the technical solution, when the rotating ring 201 rotates, the guide groove 202 can be driven to rotate, so that the circular guide rod B504 can be driven to move through the rotation of the guide groove 202, thereby driving the mobile sleeve B501 to move inwardly toward the center.

[0061] A moving rod B502 is slidably connected in the inner cavity of the moving sleeve B501, one end of the moving rod B502 is fixedly connected to one end of a connecting spring 508, the other end of the connecting spring 508 is fixedly connected to the inner cavity wall of the moving sleeve B501, the other end of the moving rod B502 is fixedly connected to a U-shaped frame B505, a driving wheel unit 506 is rotatably connected to the U-shaped frame B505, a motor 507 is fixedly connected to the side wall of the U-shaped frame B505, the output shaft end of the motor 507 extends to the driving wheel unit 506 and is fixedly connected to the driving wheel unit 506. Through the technical solution, when the moving sleeve B501 is in motion, the moving rod B502 is fixedly connected to the inner cavity wall of the moving sleeve B501. When 501 moves inwardly toward the center, the driving wheel unit 506 can be moved, and the driving wheel unit 506 can be brought into contact and pressed against the outer wall of the blasting tube. The driving wheel unit 506 can be driven to rotate by the operation of the motor 507, so that the blasting tube can be driven to move by the rotation of the driving wheel unit 506, thereby cooperating with the guiding effect of the guide wheel 404 on the blasting tube, so that the blasting tube can be moved more smoothly, so that it is convenient to insert into the blasthole, ensuring the stability during insertion, avoiding the phenomenon of offset instability, and solving the problem of collision damage caused by insufficient stability of the ordinary blasting tube fixing mechanism when the blasting tube is inserted into the blasthole in the prior art.

[0062] For further technical solutions, see Figure 8As shown, the driving wheel unit 506 includes an inner wheel 5061, an outer wheel 5062, a round head pin 5063 and a limit spring 5064. The outer wheel 5062 is rotatably connected to the arc-shaped outer wall of the inner wheel 5061. The arc-shaped inner wall of the outer wheel 5062 is provided with a plurality of circular grooves. The inner part of the inner wheel 5061 is provided with a plurality of inner cavities. The inner cavity of the inner wheel 5061 is slidably connected with a round head pin 5063. One end of the round head pin 5063 contacts the circular groove of the outer wheel 5062. The other end of the pin 5063 is fixedly connected to a limit spring 5064. Through the present technical solution, when the blasting tube encounters foreign objects blocking it during insertion, the resistance to the insertion of the blasting tube will be greatly increased due to the obstruction of the foreign objects. When the insertion resistance is greater than the force of the round head pin 5063 pressing against the outer wheel 5062, the round head pin 5063 will retract inward, causing the inner wheel 5061 to idle, thereby achieving the function of controlling the rotational torque and avoiding damage caused by excessive insertion force when the blasting tube encounters an obstruction.

[0063] For specific technical solutions, please refer to Fig. 9 , Fig.10 and Fig.11 As shown, the anti-escape component 7 includes a limiting plate frame 701, a fixed tripod 702, a locking bolt 703, a fixed cylinder 704, a movable piston A705, a movable guide rod 706, a movable circular plate 707, a buffer spring 708, a connecting hose 709, a connecting cylinder 710, a movable rod 712 and a fixed plate 713. The fixed tripod 702 is fixedly arranged at the upper edge position of the fixed sleeve 1, and the upper end of the fixed tripod 702 is fixedly connected to one end of the limiting plate frame 701, and the locking bolt 703 is threadedly connected at the other end of the limiting plate frame 701. The locking bolt 703 is threadedly connected to the fixed sleeve 1, and the middle position of the limiting plate frame 701 is fixedly connected to the fixed cylinder 704, and the movable piston A705 is slidably connected in the inner cavity of the fixed cylinder 704. The bottom surface of the movable piston A705 is fixed One end of the movable guide rod 706 is connected, and the other end of the movable guide rod 706 penetrates the bottom wall of the inner cavity of the fixed tube 704 and extends outside the wall. The bottom end of the movable guide rod 706 is fixedly connected to a movable circular plate 707, and the upper surface of the movable circular plate 707 is fixedly connected to one end of a buffer spring 708, and the other end of the buffer spring 708 is fixedly connected to the bottom surface of the limiting plate frame 701. Through the technical solution, when the blasting tube is installed and inserted, the locking bolt 703 can be unscrewed first, so that the limiting plate frame 701 can be turned over and opened without hindering the normal insertion of the blasting tube. After the blasting tube is inserted into the blasthole and fixed, the limiting plate frame 701 is turned over and reset again, and the locking bolt 703 is tightened and fixed, so that the fixed tube 704 can be fixed to the tail end of the blasting tube, and the movable circular plate 707 can be pressed against the tail end of the blasting tube;

[0064] The connecting tubes 710 are provided with several numbers, and several of the connecting tubes 710 are respectively fixed on the side walls of the fixed bracket 3. A moving piston B711 is slidably connected in the inner cavity of the connecting tube 710, and one end of a moving rod 712 is fixedly connected to the side wall of the moving piston B711. The other end of the moving rod 712 penetrates the inner cavity side wall of the connecting tube 710 and extends outside the wall. A fixing plate 713 is fixedly connected to one end of the moving rod 712. The inner cavities of several connecting tubes 710 are connected and communicated through a connecting tube 714. One end of a connecting hose 709 is fixedly connected in the inner cavity of the connecting tube 710, and the other end of the connecting hose 709 extends into the inner cavity of the fixed tube 704 and is fixedly connected to the fixed tube 704. Through the technical solution, when the blasting tube is blasted, the recoil force may be too large due to improper installation or poor blocking of the blast hole, causing the blasting tube to jump up. When the blasting tube appears to jump up, since the movable circular plate 707 is arranged at the tail end of the blasting tube, the jumped blasting tube is buffered by the buffer spring 708 to avoid excessive jumping up. At the same time, the thrust of the movable circular plate 707 when jumping up can drive the movable piston A705 to move, and then the movement of the movable piston A705 can make the gas in the inner cavity of the fixed cylinder 704 be transported to the inner cavity of the connecting cylinder 710 through the connecting hose 709, thereby pushing the movable piston B711 to move. The movement of the movable piston B711 can drive the movable rod 712 to move, thereby driving the fixed plate 713 to move, so that the fixed plate 713 moves toward the center to further clamp the blasting tube, which plays a role of auxiliary clamping and fixing. At the same time, no additional power source is required for auxiliary clamping and fixing. When the blasting tube appears to jump up, automatic auxiliary clamping and fixing are performed, which is particularly suitable for use with carbon dioxide blasting tubes.
