[0061] To further explain, the vehicle chassis 1 is also provided with a diesel engine and wheels, and the vehicle body is installed with a covering member 8 .

[0062] Working principle:

[0063] The vehicle body can move under the drive of the diesel engine. A flip mechanism 2 is provided at the front of the vehicle chassis 1. The flip frame 21 of the flip mechanism 2 can adjust the angle under the drive of the flip cylinder 22. The flip frame 21 is connected to the detection frame 31 of the detection device. In the non-working state, the sampling device 3 can be placed obliquely above the vehicle chassis 1. In the working state, the sampling device 3 is placed vertically or tilted at other angles so that the drill rod can drill samples of soil, etc.

[0064] The hydraulic motor of the power mechanism 4 transmits power to the working drill rod through the reducer, and the power mechanism 4 realizes up and down movement through the guide rail slider structure arranged on the detection frame 31 in cooperation with the lifting cylinder, thereby driving the workpiece drill rod to move up and down to drill the soil.

[0065] On both sides below the power mechanism 4, there are upper rod mechanisms 6 for replacing drill rods. The upper rod mechanism 6 includes a drill rod bin 61, a sliding mechanism 62 and a clamping finger mechanism 63. The indexing plate 611 of the drill rod bin 61 can place the drill rod and clamp it with a clamping part 612. The clamping block 6121 of the clamping part 612 clamps the drill rod through elastic parts 6122 such as springs, which is conducive to drill rod replacement and reliable clamping. The sliding mechanism 62 can drive the clamping finger mechanism 63 to move away from and close to the drill rod bin 61. The clamping finger mechanism 63 can rotate under the drive of the second motor and can clamp and release the drill rod under the drive of the clamping finger cylinder 632, thereby realizing automatic replacement of the drill rod, improving the efficiency of drill rod replacement, and reducing manpower.

[0066] The first motor 616 and the second motor are both hydraulic motors, which are provided with encoders and angle sensors, and can accurately transmit. The above hydraulic motors, encoders and angle sensors are all prior art and are only applied here.

[0067] The clamping mechanism 5 is used to further clamp the working drill rod. The dynamic clamping block 51 can rotate under the drive of the clamping cylinder and is buckled with the static clamping block 52. The threaded connection with the working drill rod and the release from the power mechanism are realized by rotation. The dynamic clamping block 51 is provided with a floating structure such as a spring, so that the working drill rod can adjust the force and reduce the damage to the drill rod thread.

[0068] The hoisting motor of the hoisting lifting mechanism 7 is arranged above the power mechanism 4 and is connected to the salvage piece through a wire rope. The salvage piece can store the drilled soil and lift the soil in the inner tube of the drill rod upward.

[0069] The exterior of the vehicle body is provided with a covering member 8 for isolating the vehicle body from rain and dust, and making the drilling rig stylish, technological and beautiful.

[0070] The drilling rig is also equipped with a variety of sensors, such as pressure, flow, displacement, angle, speed, rotation angle, image and other sensors and programmable logic PLC controllers, which can sense and process changes in the surrounding environment to adjust the output power of the diesel engine to adapt to different working conditions and achieve energy saving and environmental protection; and can sense various emergencies (such as people, large rocks, etc.) in the surrounding area to ensure the safety of the drilling rig and people. The above sensors and PLC controllers are all existing technologies.

[0071] The movement of each mechanism is controlled by a program, and a gyroscope is provided to detect the angle of the sampling device 3, so that the soil drilling operation can be performed accurately and automatically, greatly improving the work efficiency and automation level.

[0072] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the invention.
