[0023] Furthermore, a limit ring 9 is fixedly arranged on the outer side of the drill bit 6, and the limit ring 9 is rotatably connected to the mounting plate 5;

[0024] During operation, the limit ring 9 is rotatably connected to the mounting plate 5 , so that the drill bit 6 is kept balanced by the limit ring 9 when rotating.

[0025] Furthermore, a support rod 8 is fixedly connected to the top surface of the drill bit 6, and the inner wall of the support rod 8 is slidably connected to the surface of the piston 7;

[0026] During operation, the inner wall of the support rod 8 is slidably connected to the piston 7 , and the piston 7 rotates after rising to the top, so that the support rod 8 supports the piston 7 .

[0027] Furthermore, a second motor 13 is fixedly mounted on the top of the bottom plate 1, and a toothed disc 14 is fixedly connected to the output end of the second motor 13, and the toothed disc 14 is meshed with the rack 12;

[0028] During operation, the toothed disc 14 is meshed with the rack 12 , and the second motor 13 drives the toothed disc 14 to rotate, thereby controlling the height of the rack 12 and the mounting plate 5 , so as to control the lifting and lowering of the drill bit 6 .

[0029] Furthermore, a through hole 18 is formed on the surface of the bottom plate 1, and the position of the through hole 18 is located directly below the drill bit 6;

[0030] During operation, the position of the drill bit 6 is aligned with the position of the through hole 18 by means of a structural design, the ground is supported by the bottom plate 1 , and the through hole 18 facilitates the drill bit 6 to perform drilling.

[0031] Furthermore, the two protection rings 16 are fixedly connected by bolts 17, and the bottom surface of the protection ring 16 is in contact with the surface of the bottom plate 1;

[0032] During operation, the two protection rings 16 are fixedly connected by bolts 17, so that the protection rings 16 can be easily disassembled and assembled for maintenance.

[0035] Working principle: when it is necessary to drill and sample the soil, the universal wheel 2 is used to move the device to a suitable position and then the bottom plate 1 is fixed by pressing down the steel chisel 3. At this time, the first motor 11 is started by an external power supply, and the first motor 11 drives the gear set 10 to rotate and control the drill bit 6 to drill. The drill bit 6 rotates on the surface of the mounting plate 5 through the limit ring 9. At the same time, the second motor 13 is started by an external power supply, and the second motor 13 controls the mounting plate 5 to descend through the gear plate 14 and the rack 12. When the drill bit 6 descends to drill and sample the soil, the piston 7 is squeezed and rises by the soil. When the piston 7 rises to the top, the protruding part of the top of the piston 7 is higher than the support rod 8. At this time, the piston 7 is rotated to make the protruding part of the top of the piston 7 engage with the top of the support rod 8, and then the second motor 13 is reversed to extract the drill bit 6;

[0036] On this basis, when the device collects soft soil with high moisture content, the piston 7 slides upward to expel the air in the drill bit 6, so that the soil is collected inside the drill bit 6, and the possibility of scattering the soil in the drill bit 6 is reduced when the drill bit 6 is extracted. When collecting hard soil with low moisture content, the protective ring 16 is engaged with the inside of the block 15 to cover and protect the drilling position, thereby reducing the possibility of danger to the user due to splashing sand and gravel. The two protective rings 16 are installed by bolts 17, which is convenient for disassembly and maintenance of the protective rings 16.
