[0033] In the above, the camera device 3 is an observation image device, which can detect the progress of the device mining and the situation inside the mine, so that the staff can monitor the work and the situation inside in real time.

[0034] In the above, the brushless motor wheel 5 is internally installed with a disc type brushless motor, which can be controlled by remote control to move the device.

[0035] In the above, the fixed frame 45 is in the upper position when moving, and needs to be lowered when mining, the mining device 4 in the upper position can ensure that the device is not hindered when moving.

[0036] Further, in order to realize the purpose of lowering the mining device 4 when mining, refer to Figure 2 and Figure 3The shovel mining device 4 comprises two rectangular frames 42 fixedly connected to the left and right parts of the front end of the vehicle body 1, and the inner cavities of the two rectangular frames 42 are fixedly connected with limiting columns 44, and the inner cavities of the two limiting columns 44 are jointly and slidably connected with a fixing frame 45, and the front end of the middle part of the fixing frame 45 is fixedly connected with a shovel 41, and the upper ends of the two rectangular frames 42 are fixedly connected with electric telescopic cylinders 43.
