[0032] The starting mechanism includes a starting hole 301 opened on the side of the drill rod 104 close to the drill bit 106, a starting rod 302 is slidably connected to the starting hole 301, one end of the starting rod 302 is connected to the drill bit 106, and the other end of the starting rod 302 is provided with a first conductive plate 303, and a second conductive plate 304 is provided on the bottom wall of the starting hole 301, and the first conductive plate 303, the second conductive plate 304 and the distance sensor 2 are electrically connected;

[0033] It should be noted here that: by setting the starting mechanism, the initial distance measurement value of the distance sensor 2 is measured synchronously with the movement of the drill bit 106 toward the inner wall of the rock and soil, thereby protecting the drill bit 106 while reducing the error in the rock and soil depth measurement, further improving the accuracy of the depth measurement result.

[0034] It is worth noting that the model of the distance sensor 2 is AC-M18-A50 / 100. As a prior art, its specific structure and working principle have been mastered by those skilled in the art, and will not be elaborated here.

[0035] It is more optimized that an avoidance hole arranged opposite to the distance sensor 2 can be opened on the moving vehicle 101, so that the distance sensor 2 can directly measure the distance to the ground.

[0036] See also Figure 4 The starting hole 301 shown in the figure is provided with a connecting assembly for connecting the drill bit 106, and the connecting assembly includes a plurality of spline grooves 401 formed on the inner wall of the starting hole 301, and a spline rod 402 is slidably connected to each spline groove 401, and one side of each spline rod 402 is connected to the starting rod 302;

[0037] It should be noted here that: through the setting of the connecting assembly, the drill bit 106 can be driven to rotate during the rotation of the drill rod 104.

[0038] See also Figure 4 , a first spring 5 is provided in the starting hole 301 shown in the figure, one end of the first spring 5 is connected to the bottom wall of the starting hole 301, and the other end of the first spring 5 is connected to the starting rod 302 through a rotating assembly;

[0039] It should be noted here that the first spring 5 is provided to facilitate resetting of the drill bit 106 .

[0040] See also Figure 4 The rotating assembly shown in the figure includes an annular groove 601 provided at one end of the starting rod 302 away from the drill bit 106, an annular plate 602 is rotatably connected in the annular groove 601, and the other end of the first spring 5 is connected to the annular plate 602;

[0041] It should be noted here that: by setting the rotating assembly, one end of the first spring 5 is rotatably connected to the starting rod 302, thereby preventing the first spring 5 from being deformed due to the rotation of the drill rod 104.

[0042] Working principle: When measuring the depth of rock and soil, the mobile vehicle 101 is moved to the measuring point and fixed, and then the rotating motor 107 is started to drive the drill rod 104 to rotate. At the same time, under the action of the connecting component, the drill bit 106 is driven to rotate. During the rotation of the drill rod 104, the push rod motor 108 is started to push the drill bit 106 to move closer to the ground. When the drill bit 106 hits the ground, due to the resistance of the rock and soil, the drill bit 106 can only rotate on the surface of the rock and soil and cannot move into the rock and soil, thereby protecting the drill bit 106.

[0043] When the drill rod 104 moves closer to the rock and soil, the starting rod 302 at one end of the drill bit 106 will shrink into the starting hole 301. When the first conductive plate 303 and the second conductive plate 304 on the starting rod 302 abut against each other, the end face of the drill rod 104 will abut against the end face of the drill bit 106. At this time, the drill bit 106 will move downward while rotating under the driving force of the drill rod 104, thereby starting the drilling operation. At the same time, when the first conductive plate 303 and the second conductive plate 304 abut against each other, the distance sensor 2 will receive an electrical signal, thereby starting to measure the distance from the mobile vehicle 101. After the drilling is completed, the drilling depth can be calculated by the initial detection value and the end point detection value of the distance sensor, thereby further realizing the measurement of the rock and soil depth. By setting the starting mechanism, the initial distance measurement value of the distance sensor 2 is measured synchronously with the movement of the drill bit 106 toward the inner wall of the rock and soil, thereby reducing the error in the rock and soil depth measurement and further improving the accuracy of the depth measurement result.

[0046] It should be noted here that: through the setting of the cleaning mechanism, during the rotation of the drill rod 104, the piston plate 705 is driven by the driving mechanism to move reciprocatingly in the cleaning tube 702, so that the external gas is reciprocatingly drawn into the cleaning tube 702, and finally reciprocatingly sprayed onto the detection end of the distance sensor 2, thereby realizing the cleaning of the detection end of the distance sensor 2 and avoiding the dust generated by drilling covering the detection end of the distance sensor 2 and affecting the detection sensitivity.

[0050] It should be noted here that: through the setting of the driving mechanism, during the rotation of the drill rod 104, the triangular plate 802 on the mounting ring 801 will be driven to rotate. When the triangular plate 802 and the driving rod 803 are against each other, under the interaction force, the piston plate 705 at one end of the driving rod 803 will be pushed to slide in the cleaning tube 702.
