[0022] Further, a second motor 10 is provided on the top of the vehicle body 1, a threaded rod 13 is fixedly connected to the bottom of the second motor 10, a lifting plate 14 is threadedly connected to the bottom of the threaded rod 13, two connecting plates 16 are fixedly connected to both ends of the lifting plate 14, two bottom feet 18 are fixedly connected to the bottom of the connecting plate 16, a roller 12 is fixedly connected to the bottom of the bottom foot 18, and a plurality of support columns 11 are fixedly connected to the bottom of the vehicle body 1;
[0023] When sampling of coal mine geology is required, the roller 12 needs to be retracted upwards, so that the support columns 11 around the vehicle body 1 are in contact with the ground, supporting the vehicle body 1 above the ground. When the vehicle body 1 needs to be moved, the second motor 10 is started, and the second motor 10 will drive the threaded rod 13 to rotate.
