[0045] It should be noted that the telescopic arm 12 can be an electric telescopic rod, or a hydraulic or pneumatic telescopic device; at the same time, the telescopic arm 12 can also be composed in the following ways:

[0046] See also Figure 7 The telescopic arm 12 includes: a fixed arm 121 and a movable arm, and the movable arm is slidably inserted into the inner cavity of the fixed arm 121; wherein the movable arm includes a plurality of movable arms 122, and the plurality of movable arms 122 are slidably inserted together from the outside to the inside in sequence (taking three movable arms 122 as an example, the first movable arm 122 is slidably inserted into the inner cavity of the fixed arm 121, the second movable arm 122 is slidably inserted into the inner cavity of the first movable arm 122, the third movable arm 122 is slidably inserted into the inner cavity of the second movable arm 122, and so on), each movable arm 122 is installed with a linkage, and the fixed arm 121 is provided with a driving device;

[0047] Among them, see Figure 7 , Figure 8 , Fig. 9 and Fig.10The linkage comprises a pulley 123 arranged on the side wall of the movable arm 122 and a pull rope 124 arranged on the pulley 123. The side walls of the fixed arm 121 and the movable arm 122 are both provided with mounting blocks 126. Both ends of the pull rope 124 are respectively connected to the mounting block 126 on the upper movable arm 122 and the tail end of the lower movable arm 122 (several movable arms 122 are marked as the first, second, third, etc. from the outside to the inside. The first movable arm 122 is the movable arm 122 that is slidably inserted into the inner cavity of the fixed arm 121. One end of the pull rope 124 on the movable arm 122 is connected to the mounting block 126 on the fixed arm 121, and the other end is connected to the tail end of the second movable arm 122. One end of the pull rope 124 on the second movable arm 122 is connected to the mounting block 126 on the first movable arm 122, and the other end is connected to the tail end of the second movable arm 122. One end is connected to the tail end of the third moving arm 122, and so on); the driving device includes a driving member 125 (driving motor), a rotating member 127 (the rotating member 127 can be a driven gear, and a driving gear is provided on the output shaft of the driving motor, and the driving gear is meshed with the driven gear), a screw 129 and a screw sleeve 128; the screw 129 is rotatably arranged in the inner cavity of the fixed arm 121, and the screw 129 extends along the length direction of the fixed arm 121. The rotating member 127 is fixedly sleeved on the outer wall of the screw 129, the driving member 125 is arranged on the side wall of the fixed arm 121, and the screw sleeve 128 is arranged at the tail end of the outer first-stage moving arm 122 (the outer first-stage moving arm 122 refers to the moving arm 122 that is slidably inserted into the inner cavity of the fixed arm 121), and the screw sleeve 128 is sleeved on the outer wall of the screw 129.

[0048] It should also be noted that the working method of the telescopic arm 12 is that the driving member 125 is energized to drive the rotating member 127 to rotate with the screw 129, so that the screw sleeve 128 moves, and the first mobile arm 122 moves toward the outside of the fixed arm 121; when the first mobile arm 122 moves toward the outside of the fixed arm 121, the pulley 123 on the mobile arm 122 will also move, thereby increasing the distance between it and the fixed arm 121, and causing the pull rope 124 on the pulley 123 to pull the second mobile arm 122 to move toward the outside of the first mobile arm 122; similarly, when the second mobile arm 122 moves, the third mobile arm 122 will also be moved, and so on, so that several mobile arms 122 move at the same time, so that the telescopic arm 12 is extended.

[0049] Working principle: When the fixing part is a clamp 13, a layer of cloth is wrapped around the outside of the explosive, and after glue is applied to the surface of the cloth, the explosive is clamped by the clamp; then the remote control vehicle body 1 moves, and when it reaches the entrance of the chute, the first driving member 8 extends to drive the rotating frame 5 to rotate downward, and the support 6 also rotates downward, and then the second driving member 11 contracts to rotate the second connecting rod 10, and moves the first connecting rod 9, so that the support 6 rotates downward again, which is used to make the height of the chute dredging member installed on the top of the support 6 lower than the height of the vehicle body 1 (that is, the telescopic arm 12 is laid down), so that the overall height of the remote control conveyor vehicle Lower; control the vehicle body 1 to continue to move, so that the vehicle body 1 enters the interior of the ore chute, the second driving member 11 extends, and drives the second connecting rod 10 to rotate in the opposite direction, so that the first connecting rod 9 pulls the support 6 to rotate upward, and the first driving member 8 contracts, so that the rotating frame 5 drives the support 6 to rotate upward, so that the telescopic arm 12 stands upright; then the telescopic arm 12 extends, so that the clamp 13 with the explosive contacts the bottom of the ore in the blocked area, and the explosive is bonded to the bottom of the ore, the clamp 13 releases the explosive, and at the same time the telescopic arm 12 contracts and then falls down, and after the vehicle body 1 exits the interior of the ore chute, the explosive is detonated to dredge the ore chute;

[0050] When the fixing member is the support frame 14, the explosive is bundled on the first pipe 141 (or the explosive is fixed by other means), and then the remote control vehicle body 1 moves. When it reaches the entrance of the chute, the first driving member 8 extends to drive the rotating frame 5 to rotate downward, and the support 6 also rotates downward. Then the second driving member 11 contracts to rotate the second connecting rod 10, and moves with the first connecting rod 9, so that the support 6 rotates downward again, which is used to make the height of the chute dredging member installed on the top of the support 6 lower than the height of the vehicle body 1 (that is, the telescopic arm 12 is laid down), so that the overall height of the remote control conveyor vehicle is reduced; the vehicle body 1 is controlled to continue to move, so that the vehicle body 1 enters the interior of the chute, and the second driving member 11 extends, and drives the second connecting rod 10 to rotate in the opposite direction, so that the first connecting rod 9 is moved downward, and the second connecting rod 10 rotates in the opposite direction, so that ... After the rod 9 pulls the support 6 to rotate upward, the first driving member 8 contracts, causing the rotating frame 5 to rotate upward with the support 6, so that the telescopic arm 12 stands upright; then after the telescopic arm 12 is extended for a distance, the rotating member 144 rotates, and after the first pipe 141 and the second pipe 142 are rotated from a vertical state to a horizontal state, the telescopic arm 12 is extended again, so that the explosive is closer to the bottom of the ore, the driving assembly 143 works, so that the second pipe 142 moves to the outside of the first pipe 141 and contacts the inner wall of the chute, and the support frame is stuck inside the chute. The telescopic arm 12 contracts, so that the clamping connection between the telescopic arm 12 and the rotating member 144 is disconnected, and then the telescopic arm 12 is laid down again. After the vehicle body 1 withdraws from the inside of the chute, the explosive is detonated to clear the chute.

[0051] It should be noted that during the installation of explosives, the camera will capture the situation inside the chute and feed it back to the staff, so that the staff can remotely adjust the position of the remote-controlled transport vehicle according to the situation inside the chute, ensure that the explosives are accurately installed in the optimal blasting area, and ensure the effect of dredging the chute.
