[0036] The bending drive mechanism 3 is connected to the continuous bending joint 2 and is used to drive the continuous bending joint 2 to bend.

[0037] When in use, the charge tube 4 is inserted into the limiting hole 211 of each of the fixed frames 21 in turn, and then the continuous bending joint 2 is driven to bend by the bending drive mechanism 3 according to the orientation of the head end of the charge tube 4 relative to the blast hole, and the turntable 12 is driven to rotate by the rotating drive member 13. The turntable 12 drives each of the fixed frames 21 to rotate, so that the head end of the charge tube 4 is aligned with the blast hole, thereby realizing the mechanization of the charge tube aligning with the blast hole, eliminating the need for manual alignment of the blast hole, improving safety, and reducing the labor intensity of workers.

[0040] In one embodiment, see Figure 2 , Figure 4 and Figure 5The continuous bending joint 2 further includes a plurality of middle connecting rods 24, which are arranged between two adjacent fixed frames 21, and the two ends of each middle connecting rod 24 are respectively hinged to the center of two adjacent fixed frames 21;

[0041] An upper telescopic member 22 and a lower telescopic member 23 are disposed between each two adjacent fixed frames 21, and the fixed end and the movable end of each upper telescopic member 22 are respectively hinged to the upper ends of the two adjacent fixed frames 21, and the fixed end and the movable end of each lower telescopic member 23 are respectively hinged to the lower ends of the two adjacent fixed frames 21;

[0042] The upper telescopic member 22 includes an upper cylinder body 221, an upper piston 222 and an upper slide bar 223. The upper piston 222 is slidably sealed and disposed in the upper cylinder body 221 to form an upper accommodating chamber with a variable volume. The upper cylinder body 221 is provided with an upper liquid port 2211 communicating with the upper accommodating chamber. One end of the upper slide bar 223 is fixed to the upper piston 222, and the other end of the upper slide bar 223 is hinged to the upper end of the fixed frame 21.

[0043] The lower telescopic member 23 includes a lower cylinder body 231, a lower piston 232 and a lower slide rod 233. The lower piston 232 is slidably sealed and disposed in the lower cylinder body 231 to form a lower accommodating chamber with a variable volume. The lower cylinder body 231 is provided with a lower liquid port 2311 communicating with the lower accommodating chamber. One end of the lower slide rod 233 is fixed to the lower piston 232, and the other end of the lower slide rod 233 is hinged to the lower end of the fixed frame 21.

[0044] The bending drive mechanism 3 includes an upper main pipe 31, a lower main pipe 32, an oil tank 33, an upper liquid return valve 34, a lower liquid return valve 35, a liquid pump 36, an upper liquid inlet valve 37 and a lower liquid inlet valve 38. The upper main pipe 31 is connected to each of the upper liquid ports 2211, the lower main pipe 32 is connected to each of the lower liquid ports 2311, one end of the upper liquid return valve 34 is connected to one end of the upper main pipe 31, the other end of the upper liquid return valve 34 is connected to the oil tank 33, and the lower liquid return valve 35 is connected to the oil pump 36. One end of the valve 35 is communicated with one end of the lower main pipe 32, the other end of the lower liquid return valve 35 is communicated with the oil tank 33, the inlet of the liquid pump 36 is communicated with the oil tank 33, one end of the upper liquid inlet valve 37 is communicated with the outlet of the liquid pump 36, the other end of the upper liquid inlet valve 37 is communicated with one end of the upper main pipe 31, one end of the lower liquid inlet valve 38 is communicated with the outlet of the liquid pump 36, and the other end of the lower liquid inlet valve 38 is communicated with one end of the lower main pipe 32.

[0045] During use, when it is necessary to control the continuous bending joint 2 to bend uniformly upward, open the lower liquid inlet valve 38 and the upper liquid return valve 34, close the upper liquid inlet valve 37 and the lower liquid return valve 35, and then open the liquid pump 36. The liquid pump 36 sucks the oil in the oil tank 33 to the lower main pipe 32, and then enters each lower liquid port 2311 from the lower main pipe 32, thereby pushing each lower piston 232 to extend. When each lower piston 232 extends, each fixed frame 21 will be equivalent to the rotation of the middle connecting rod 24, thereby pushing each upper piston 222 to retract, and making the oil in each upper cylinder body 221 return to the oil tank 33 through the upper main pipe 31, thereby realizing the continuous bending joint 2 to bend uniformly upward. Similarly, when it is necessary to control the continuous bending joint 2 to bend uniformly downward, open the upper liquid inlet valve 37 and the lower liquid return valve 35, close the lower liquid inlet valve 38 and the upper liquid return valve 34, and then open the liquid pump 36.

[0046] Preferably, a threading hole 112 for the upper main pipe 31 and the lower main pipe 32 to pass through is opened at the lower end of the fixed plate 11, and the rotating drive motor 131 is a stepping motor. When the rotating drive motor 131 rotates, it is set to a maximum of 180° clockwise or counterclockwise. In this way, it can be ensured that the turntable 12 can only rotate clockwise or counterclockwise half a circle at most, and the upper main pipe 31 and the lower main pipe 32 should have a certain length to ensure that when the turntable 12 rotates clockwise or counterclockwise half a circle, the length of the upper main pipe 31 and the lower main pipe 32 can still meet the requirements.

[0047] In this embodiment, since each of the lower telescopic members 23 is telescoped to the same extent, it can be ensured that when the charge tube 4 is bent, the bending degrees of each part are consistent, so that there will be no local excessive bending, which can improve the service life of the charge tube 4 and the smoothness of the explosive transportation in the charge tube 4.

The bending drive mechanism 3 further includes a plurality of lower telescopic connecting tubes 392, one end of which is in communication with the lower liquid port 2311, and the other end of which is in communication with the lower main pipe 32. The lengths of the upper telescopic connecting tubes 391 and the lower telescopic connecting tubes 392 are variable, so as to adapt to the bending of the continuous bending joint 2.

[0049] In one embodiment, see Figure 2 , Figure 4 and Figure 5The oil tank 33 is provided with a first interface, a second interface and a third interface. The first interface is connected to the other end of the upper liquid return valve 34, the second interface is connected to the other end of the lower liquid return valve 35, and the third interface is connected to the inlet of the liquid pump 36.

[0051] In one embodiment, see Figure 2 , Figure 4 and Figure 5 The bending drive mechanism 3 also includes a drain pipe 362, one end of which is connected to the outlet of the liquid pump 36, and the other end of the drain pipe 362 is connected to one end of the upper liquid inlet valve 37 and one end of the lower liquid inlet valve 38.

[0052] In one embodiment, see Figure 1 and Figure 2 The charge tube guiding device also includes a moving trolley 5, and the fixed plate 11 is fixed to the moving trolley 5. The moving trolley 5 is self-powered and can turn, so it can assist the charge tube guiding device in guiding the charge tube.

[0053] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail: when in use, the charging tube 4 is inserted into the limiting holes 211 of each of the fixed frames 21 in sequence, and then the continuous bending joint 2 is driven to bend by the bending drive mechanism 3 according to the orientation of the head end of the charging tube 4 relative to the blast hole, and the turntable 12 is driven to rotate by the rotating drive member 13, and the turntable 12 drives each of the fixed frames 21 to rotate, so that the head end of the charging tube 4 is aligned with the blast hole, thereby realizing the mechanization of the charging tube aligning with the blast hole, without the need for manual alignment of the blast hole, improving safety, and reducing the labor intensity of workers.
