[0025] A second driving assembly 7 for driving the second end plate 32 to rotate along the first central axis is provided on the side wall of the column 11. The second driving assembly 7 includes a second cylinder 71 and a second hinge block 72. The second hinge block 72 is fixed on the second end plate 32. The end of the second cylinder 71 is hinged to the side wall of the column 11. The piston rod of the second cylinder 71 is hinged to the hinge block. When the second end plate 32 does not rotate, the piston rod of the second cylinder 71 is in the extended state. When the second end plate 32 rotates, the piston rod of the second cylinder 71 contracts.

[0026] A blocking assembly 8 for preventing the first central rod 2 from rotating is provided on the mounting plate 1. The blocking assembly 8 includes a blocking plate 81, a blocking block 82 and a third cylinder 83. The blocking plate 81 is fixed to the first central rod 2.

When the drill pipe moves below the rock drill 111 and the drill pipe is installed on the rock drill 111, the second clamping plate 53 opens. Then, the third cylinder 83 drives the blocking block 82 to disengage from the insertion grooves 811, and the piston rod of the second cylinder 71 contracts, driving the second end plate 32 and the first end plate 31 to rotate by a certain angle, so that the first clamping plate 52 disengages from the drill pipe. Then, the piston of the first cylinder 41 contracts by a certain distance, driving the rotating rod 12 to rotate and the mounting block 51 to rotate by a certain angle, so that when the second cylinder 71 drives the first end plate 31 and the second end plate 32 to rotate to the initial position, the first clamping plate 52 and the second clamping plate 53 do not interfere with the drill pipe below the rock drill 111.

[0028] The automatic unloading rod of the utility model is controlled by a control system. The system is based on the 5G network and uses the data transfer platform deployed in the MEC to establish communication between the remote operation room and the remote control terminal of the medium-deep hole jumbo. The remote control terminal of the medium-deep hole jumbo is connected to the medium-deep hole jumbo through physical interfaces such as CAN, digital quantity, and analog quantity acquisition interfaces. The instructions of the operation room are sent to the terminal through the 5G network, and the video signal is transmitted back through the 5G network to monitor the underground mine site environment, realizing a series of operation processes such as remote drilling and automatic unloading rod of the medium-deep hole jumbo in the underground mine. The staff will be freed from the relatively dangerous underground mine and conduct remote control in the operation room.

[0029] Using 5G networking, the operation control console is transferred to a safe surface dispatching room. For the automatic unloading rod function, it is no longer necessary for the operator to operate the jumbo for unloading the rod throughout the process. Just select the automatic operation on the remote operation platform, and the system will perform automatic operation according to the real-time vehicle equipment status. In case of abnormal situations, it will exit the automatic process and upload an alarm prompt. The automatic unloading rod control of the medium-deep hole jumbo greatly simplifies the operation process of the medium-deep hole jumbo, reduces the labor intensity of workers, improves the working environment of the staff, and effectively improves the vehicle operation efficiency.
