[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0052] The fixing frame 1 is placed at the desired position, the moving wheels 3 at the bottom of the base 2 can be moved a small distance, and the fixing rod 4 then fixes the position of the base 2;

[0053] Range mapping organization 5 includes:

[0054] A limiting rod 53, the limiting rod 53 is fixedly connected to the top of the base 2;

[0055] A limiting ring 52, the limiting ring 52 is sleeved on the outer wall of the limiting rod 53;

[0056] A fixing plate 51, the outer wall of the fixing plate 51 is fixedly connected to the outer wall of the limiting ring 52;

[0057] A first detection lens 54, which is fixedly connected to the outer wall of the fixing plate 51;

[0058] A second detection lens 55, which is fixedly connected to the bottom of the fixing plate 51;

[0059] A lifting assembly 58, the lifting assembly 58 is fixedly connected to the outer wall of the base 2;

[0060] The first detection lens 54 and the second detection lens 55 can shoot the scene, and then the control element records the scene, measures the size of each object in the scene in the first detection lens 54 and the second detection lens 55, and then manually measures the size of one of the objects and inputs it into the control element for comparison.

[0061] The lifting assembly 58 includes a power component 581, which is fixedly connected to the outer wall of the base 2. The outer wall of the power component 581 is rotatably connected to the first pulley 582, the outer wall of the fixed frame 1 is fixedly connected to the second pulley 583, the inner top of the fixed frame 1 is fixedly connected to the third pulley 584, the outer wall of the fixed plate 51 is fixedly connected to the fourth pulley 586, and the outer walls of the third pulley 584 and the second pulley 583 are sleeved with a pull rope 585.

[0062] Two ends of the pull rope 585 are fixedly connected to the first pulley 582 and the fourth pulley 586 respectively.

[0063] The outer wall of the limiting rod 53 is sleeved with a ring 57, the bottom of the ring 57 is fixedly connected with a buffer spring 56, and the buffer spring 56 is fixedly connected to the outer wall of the base 2;

[0064] The fixed plate 51 is mounted on the limit rod 53 through the limit ring 52, thereby limiting the movement range of the fixed plate 51. The power component 581 is powered on to drive the first pulley 582 to rotate. The first pulley 582 will wrap around the pull rope 585 during rotation. After the pull rope 585 passes through the second pulley 583 and the third pulley 584, the pull rope 585 pulls the fourth pulley 586, and then drives the fixed plate 51.

[0068] The motor 67 drives the drill bit 68 to rotate and drill into the soil below. The spring 65 is set between the motor 67 and the connecting rod 64, thereby buffering the reaction force exerted on the motor 67. When the motor 67 rises, it will drive the scale plate 66 to leak out from the connecting rod 64. The staff nearby can observe that when the hardness of the soil below is too high, they can observe the scale plate 66 and then suspend the surveying.
