[0106] The support plate 602 is disposed on the U-shaped support frame 601, and the U-shaped support plate 603 is disposed on the support plate 602, and the opening 206 of the U-shaped support plate 603 faces the walking chassis 1;

[0107] The clamping module is disposed on the U-shaped support plate 603 , and the clamping module clamps the outer cylinder 302 .

[0108] The U-shaped support plate 603 is provided to provide support for the entire clamping module.

[0109] In this embodiment, please refer to Figure 8 and Fig. 9 The clamping module includes a first clamping block 604, a second clamping block 605, a positive and negative threaded rod 606, an arc-shaped through groove 607, a limit rod 608 and a first rotating power element 609;

[0110] The first clamping block 604 and the second clamping block 605 clamp the outer cylinder 302, the forward and reverse threaded rod 606 is rotatably installed between the two side plates of the U-shaped support plate 603, the forward threaded section of the forward and reverse threaded rod 606 is threadedly connected to the first clamping block 604, and the reverse threaded section of the forward and reverse threaded rod 606 is threadedly connected to the second clamping block 605;

[0111] The two side plates of the U-shaped support plate 603 are provided with through arc-shaped through grooves 607, and the two limiting rods 608 are respectively located in the two arc-shaped through grooves 607, one of the limiting rods 608 is fixedly connected to the first clamping block 604, and the other limiting rod 608 is fixedly connected to the second clamping block 605, and the limiting rods 608 are extended out of the outer wall of the U-shaped support plate 603;

[0112] When the limiting rod 608 contacts one end of the arc-shaped through slot 607, the center line of the first clamping block 604 and the second clamping block 605 forms an angle a with the horizontal plane, and the inclination angle of the guide slide plate 501 is b, a=b;

[0113] When the limiting rod 608 contacts the other end of the arc-shaped through slot 607, the center lines of the first clamping block 604 and the second clamping block 605 are perpendicular to the horizontal plane;

[0114] The lower end surface of the fixing block 311 is in contact with the top walls of the first clamping block 604 and the second clamping block 605;

[0115] The first rotation power element 609 provides rotation power for the forward and reverse threaded rod 606;

[0116] The first rotating power element 609 is not limited here and is only used to provide rotational power output, which can be provided directly by the motor, or the motor can provide rotational power to the forward and reverse threaded rod 606 through a gear set, or the motor can provide rotational power to the forward and reverse threaded rod 606 through a belt.

[0117] When the slit tube storage container 204 falls from the discharge port 203 into the guide chute plate 501, the clamping space of the first clamping block 604 and the second clamping block 605 is located at the exit of the guide chute plate 501, that is, the end of the guide chute plate 501 with a lower horizontal height. When the bottom end of the slit tube storage container 204 falls out of the guide chute plate 501, it enters between the first clamping block 604 and the second clamping block 605, and the bottom wall of the slit tube storage container 204 will fit with the bottom plate of the U-shaped support plate 603, so that the slit tube storage container 204 stops sliding down.

It continues to reverse, and the first clamping block 604 and the second clamping block 605 will be driven through the forward and reverse threaded rods 606 to clamp the outer cylinder 302 of the slit tube storage device 204. When the slit tube storage device 204 is clamped, the first rotating power element 609 rotates forward, so that the slit tube storage device 204 rotates upward, so that the slit tube storage device 204 is in a vertical state. At this time, the limit rod 608 conflicts with the other end of the arc groove 607, and continues to rotate forward, which will drive the first clamping block 604 and the second clamping block 605 to release the slit tube storage device through the forward and reverse threaded rods 606. The outer cylinder 302 of the device 204 releases the first clamping block 604 and the second clamping block 605, so that the slider 304 can pass between the first clamping block 604 and the second clamping block 605, and the fixing block 311 contacts the upper end surfaces of the first clamping block 604 and the second clamping block 605. Under the action of the fixing block 311, the outer cylinder 302 suddenly stops falling, and the outer cylinder 302 will continue to move downward under the action of the downward inertia, so that the limit block 306 moves outward and extends out of the outer cylinder 302, and the limit block 306 rotates outward, so that the slit tube storage device 204 can fall out of the inner cylinder 301, and the slit tube storage device 204 is placed in the blast hole.

[0119] In this embodiment, please refer to Fig.10 , the slit tube placement device also includes a first rotating column 701 and a second rotating power element 708;

[0123] By setting the first rotating column 701, the support plate 602 can be rotated. When the slit tube placement device is not needed and is idle, the support plate 602 can be rotated downward and retracted, thereby increasing the transportation convenience of the entire device.

[0124] In this embodiment, please refer to Figure 1 The slit tube placement device further includes a third rotating power element 709, a roller 702, a rotating disk 703 and a steel wire 704;

[0125] The bottom plate of the U-shaped support plate 603 is slidably connected to the support plate 602, and the sliding direction of the U-shaped support plate 603 is perpendicular to the rotation axis direction of the first rotating column 701. The roller 702 is rotatably mounted on the upper end surface of the support plate 602, and the rotation axis direction of the roller 702 is perpendicular to the sliding direction of the U-shaped support plate 603;

[0126] One end of the steel wire 704 is fixedly connected to the U-shaped support plate 603, and the other end of the steel wire 704 is passed around the roller 702 and fixedly connected to the turntable 703. The third rotating power element 709 provides rotating power for the turntable 703, and the third rotating power element 709 is fixedly installed on the support plate 602;

[0127] The third rotating power element 709 is not limited here, and is only used to provide rotational power output, which can be provided directly by the motor, or the motor can provide rotational power to the turntable 703 through a gear set, or the motor can provide rotational power to the turntable 703 through a belt.

[0128] When the slitting tube 312 is placed in the blast hole, its inner tube 301 and outer tube 302 will also partially extend into the blast hole. By starting the third rotating power element 709, the turntable 703 is driven to rotate, thereby driving the U-shaped support plate 603 to rise through the steel wire 704, so that the inner tube 301 and outer tube 302 entering the blast hole are pulled out of the blast hole.

[0129] In this embodiment, please refer to Fig.10 The slit tube placement device further includes a second rotating column 705, a fourth rotating power element 710, an upper limit block 706 and a lower limit block 707;

[0132] The lower limit block 707 is fixedly installed on the walking chassis 1, and the upper end surface of the lower limit block 707 is in contact with the lower end surface of the U-shaped support frame 601. The lower limit block 707 can also provide support for the U-shaped support frame 601, and it is also convenient to ensure the support of the U-shaped support frame 601.

[0133] The second rotating column 705 can be used to drive the support plate 602 to swing backward, loosen the first clamping block 604 and the second clamping block 605, and allow the slit tube storage device 204 to fall to the ground, thereby ensuring the filling of the next blast hole.

[0134] In summary, the present invention places a plurality of slit tube storage containers 204 in the storage space of each layer, and pushes the push plate 401 through the push force element 402 to drive the sliding plate 202 to slide, thereby pushing the slit tube storage container 204 to fall out of the discharge port 203, enter the guide slide plate 501, and then slide to between the first clamping block 604 and the second clamping block 605. Through the cooperation of the limit rod 608 and the positive and negative threaded rod 606, the first clamping block 604 and the second clamping block 605 can clamp the slit tube storage container 204. After clamping, the first clamping block 604 and the second clamping block 605 are rotated to vertical, and the walking chassis 1 is moved to the slit tube storage container 204 to align with the blast hole, and the first clamping block 604 and the second clamping block 605 are released, and the slit tube storage container 204 will fall into the blast hole. When the lower end surface of the fixed block 311 is aligned with the first clamping block 604 and When the upper end surfaces of the second clamping block 605 are in contact, the outer cylinder 302 stops suddenly, and the inner cylinder 301 will slide down under the action of inertia, so that the slit tube 312 falls out of the inner cylinder 301 into the blast hole, and the third rotating power element 709 is started to drive the turntable 703 to rotate, thereby driving the U-shaped support plate 603 to rise through the steel wire 704, so that the inner cylinder 301 and the outer cylinder 302 entering the blast hole are pulled out of the blast hole, and the support plate 602 is driven to swing backward by the fourth rotating power element 710, so that the slit tube storage device 204 in the support plate 602 is high in front and low in the back, and the U-shaped support plate 603 descends, and the slit tube storage device 204 will fall out of the support plate 602, and the first clamping block 604 and the second clamping block 605 are released, so that the slit tube storage device 204 will completely fall out of the support plate 602, which can ensure that the slit tube 312 of the next blast hole is filled.
