[0002] In order to test various physical and mechanical properties of soil (such as density, water content, void ratio, liquid limit, plastic limit, compressive strength, etc.), it is necessary to use a soil sampling drill to sample the soil at a specific location. When sampling, the drill must be started first, then the drill bit is aligned with the sampling location and the drill is pressed down to make the drill bit drill into the soil for sampling.

[0003] For example, CN219015685U discloses a portable shallow soil drilling and sampling device, comprising: a fixed cylinder; a movable plate disposed inside the fixed cylinder, wherein a motor is fixed to the bottom of the movable plate, a connecting shaft is connected to the bottom end of the motor, and a sampling cylinder is disposed at the bottom end of the connecting shaft, wherein openings are provided on both sides of the sampling cylinder, and a drill bit is fixed to the bottom end of the sampling cylinder; a hydraulic cylinder fixed to the top of the fixed cylinder, wherein a hydraulic rod is disposed at the bottom end of the hydraulic cylinder, one end of the hydraulic rod extending into the fixed cylinder and fixedly connected to the movable plate. This utility model, through the cooperation of a fixed sleeve, a rotating rod, a fixed knob, and a sliding groove, can drive multiple supports to rotate simultaneously by moving the fixed sleeve up and down, thereby facilitating quick adjustment of the opening angle of the supports to adjust according to different terrains, resulting in high work efficiency and greatly improving the applicability of the device.

[0029] The leveling structure also includes a limiting mounting plate 104 and position adjusting screws 105; the limiting mounting plate 104 is fixedly connected to the lower end face of the guide connecting plate 102; three position adjusting screws 105 are provided, and the three position adjusting screws 105 are evenly distributed and threadedly connected to the outside of the limiting mounting plate 104, and the three position adjusting screws 105 are all slidably connected to the movable mounting base 1.

[0037] The specific usage and function of this embodiment are as follows: When the drill bit collides with the rock, the increased impact force on the drill bit causes the extension connecting rod 6 to drive the drill bit to slide upward and compress the damping elastic element 7. At this time, the limiting mounting slot 601 slides outside the bolt to guide the movement of the extension connecting rod 6. When the extension connecting rod 6 moves, it will drive the extrusion plate 602 to move upward and extrude the push-button switch 401, causing the drilling drive to stop and the reciprocating self-locking drive 3 to reverse, causing the drill bit to move out of the soil.
