The middle of the connecting bar 210 is rotatably connected to a second lead screw 211. The other end of the second lead screw 211 is fixedly connected to the output end of the second stepping motor 213. A moving member 212 is threadedly connected to the second lead screw 211.

A first connecting rod 223 is also fixedly installed inside the connecting frame 221. Two groups of first clamping members 225 are slidably connected to the outer surface of the first connecting rod 223. The thread directions of the two ends of the first screw rod 222 are opposite, and the two groups of first clamping members 225 are respectively threadedly connected to the two ends of the outer surface of the first screw rod 222.

The output end of the transmission motor 226 is fixedly connected to a driving gear 227 that meshes with the driven gear 228.

[0023] Those skilled in the art can understand that the output end of the first servo motor 224 drives the first screw rod 222 to rotate, causing the two groups of first clamping members 225 to approach or move away from each other. When approaching, the core cutter 110 is clamped, and when moving away, the clamping is released; the output end of the first stepping motor 204 drives the first lead screw 202 to rotate, causing the lifting plate 205 to move up and down, driving the core cutter 110 in the clamped state to move up and down; the output end of the second stepping motor 213 drives the second lead screw 211 to rotate, causing the moving member 212 to move along the outer surface of the second lead screw 211, making the scissor telescopic member 218 in a stretched or retracted state.

[0024] Embodiment 3 Please refer to Figure 11 and Figure 12 As shown in the figure, the lifting and clamping mechanism 3 includes an electric lifting rod 302 and a second clamping member 307. A support plate 301 is welded inside the frame 1. The electric lifting rod 302 is fixedly installed in the middle of the top of the support plate 301.

The thread directions of the two ends of the second screw rod 304 are opposite. There are two groups of second clamping members 307, which are respectively threadedly connected to the two ends of the outer surface of the second screw rod 304.

The output end of the electric telescopic rod 309 is fixedly connected with a hammering plate 310.

[0025] Those skilled in the art can understand that when the core cutter 110 is transferred to the inside of the frame 1 by the transfer clamping mechanism 2 and the core cutter 110 is directly below the mounting plate 303, the output end of the second servo motor 306 drives the second screw rod 304 to rotate, so that the two groups of second clamping members 307 approach each other to clamp the top of the circumferential surface of the core cutter 110; then the output end of the electric lifting rod 302 drives the clamped core cutter 110 to move downward and presses the core cutter 110 into the soil. It should be noted that the top of the circumferential surface of the core cutter 110 is wrapped by the second clamping members 307. Therefore, the above pressing operation cannot completely bury the core cutter 110 into the soil. At this time, the two groups of second clamping members 307 move away from each other to release the clamping of the core cutter 110. Secondly, the output end of the electric telescopic rod 309 extends, so that the hammering plate 310 is located below the middle of the mounting plate 303. Then the output end of the electric lifting rod 302 drives the hammering plate 310 to move downward, and the hammering plate 310 hammers the top of the core cutter 110, so that the core cutter 110 is completely buried in the soil. Embodiment 4 Please refer to Figure 3 、 Figure 8 and Figure 9 As shown in, the coating mechanism 4 includes a storage tank 401, which is installed in the groove opened on the right side of the frame 1.

[0026] Please refer to Figure 8 As shown in, the coating mechanism 4 further includes an L-shaped plate 408, which is fixedly connected to the right side of the frame 1. A fifth electric push rod 409 is rotatably connected to the outer side of the vertical plate of the L-shaped plate 408.

[0027] Those skilled in the art can understand that the output end of the sixth electric push rod 411 drives the arc-shaped smearing plate 412 to move upward, so that the arc-shaped smearing plate 412 contacts the discharging end of the storage tank 401. Vaseline is stored inside the storage tank 401. The output end of the third servo motor 406 drives the two extrusion plates 407 to approach each other, extrude the storage tank 401, and open the valve 413, so as to extrude the vaseline. Then, the output end of the fifth electric push rod 409 extends, driving the mounting block 410 to move to the left, so that the arc-shaped smearing plate 412 moves to the left, and then the vaseline is smeared all over the arc-shaped smearing plate 412. Moreover, the present invention is also provided with a fourth electric push rod 402, which can adjust the height of the two extrusion plates 407 to facilitate pressing different height parts of the storage tank 401.

[0029] Those skilled in the art can understand that after the core cutter 110 is completely buried in the soil, the output end of the first driving motor 503 drives the rotating plate 502 to rotate by an angle of 90 degrees. At this time, the seventh electric push rod 504 is directly above the center point of the core cutter 110. The output end of the eighth electric push rod 509 extends to drive the soil loosening knife 510 to move, so that the soil loosening knife 510 is directly above the soil at the outer edge of the core cutter 110. Secondly, the output end of the seventh electric push rod 504 drives the soil loosening knife 510 to move downward and completely extend into the soil. Then, the output end of the second driving motor 505 drives the driving wheel 506 to rotate. Driven by the belt 507, the driven wheel and the seventh electric push rod 504 rotate as a whole. Furthermore, the soil loosening knife 510 is in a rotating state, loosening the soil at the outer edge of the core cutter 110. Then, continue to control the extension of the output end of the eighth electric push rod 509 and repeat the above operation until the soil at the outer edge of the core cutter 110 is loosened over a large area.

[0030] Example 6 Please refer to Figure 2 and Figure 3 As shown, the knocking mechanism 6 includes a cylinder 601. The cylinder 601 is fixedly installed on the right side of the drying box 101. The output end of the cylinder 601 extends into the drying box 101 and is fixedly connected to the knocking head 602. And at the top right of the frame 1, there is a control panel 111. Inside the control panel 111, there are integrated a shooting module, a data transmission module, a preset module and a calculation module. The shooting module is used to take pictures of the indicating meter 109. In the preset module, there are stored the moisture content calculation formula, the wet density calculation formula and the dry density calculation formula. The data transmission module reads the taken indication and transmits it to the calculation module for calculating the moisture content, the wet density and the dry density.

[0031] Those skilled in the art can understand that the calculation formulas stored in the preset module are: The calculation formula for the moisture content is: 00%; The calculation formula for the wet density is: ; The calculation formula for the dry density is: ; Embodiment 7 Please refer to Figure 2 and Figure 11 As shown, a notch is formed through the top of the drying box 101. A cover plate 104 is installed on the top of the notch. The cover plate 104 is fixedly connected to the output end of the first electric push rod 105. The first electric push rod 105 is fixedly installed on the top of the drying box 101. A sealing plate 107 is arranged on the front side of the drying box 101. A second electric push rod 106 is arranged on the top of the frame 102. The top of the sealing plate 107 is fixedly connected to the output end of the second electric push rod 106. On both sides of the frame 1, third electric push rods 112 are installed. The height of the third electric push rod 112 on the right side is lower than that of the third electric push rod 112 on the left side. The output ends of both third electric push rods 112 are fixedly connected with scraping plates 113.

[0032] The working principle and usage process of this device: First, move the device to the soil compacted after the hydraulic buried pipe, and fix the device through the ground anchor. At the beginning, the ring knife 110 is in the state of being clamped by two groups of first clamping members 225 (as Figure 3In the state shown, the output end of the second stepping motor 213 drives the second lead screw 211 to rotate, causing the moving member 212 to move along the outer surface of the second lead screw 211, so that the scissor expansion member 218 is in a stretched state, and the first sliding cylinder 207, the second sliding cylinder 208, and the third sliding cylinder 209 all extend out of the fixed cylinder 206 synchronously. As a result, the cutting ring 110 in the clamping state moves forward and extends into the interior of the frame 1, and the cutting ring 110 is directly below the mounting plate 303; Secondly, the output end of the transmission motor 226 drives the driving gear 227 to rotate, causing the driven gear 228 and the fixed cylinder 206 as a whole to rotate, driving the connecting frame 221 to rotate, and changing the originally vertical cutting ring 110 to a horizontal state; Then, the output end of the sixth electric push rod 411 drives the arc-shaped smearing plate 412 to move upward, so that the arc-shaped smearing plate 412 contacts the discharge end of the storage tank 401. Vaseline is stored inside the storage tank 401. The output end of the third servo motor 406 drives the two pressing plates 407 to approach each other, squeeze the storage tank 401, and open the valve 413, thereby squeezing out the vaseline. The output end of the fifth electric push rod 409 extends, driving the mounting block 410 to move to the left, so that the arc-shaped smearing plate 412 moves to the left, and then the vaseline is smeared all over the arc-shaped smearing plate 412; Next, the output end of the fifth electric push rod 409 continues to extend, driving the mounting block 410 to continue to move to the left, so that the arc-shaped smearing plate 412 moves to the left and extends into the interior of the horizontally placed cutting ring 110. At this time, the sixth electric push rod 411 is outside the cutting ring 110. Under the action of the sixth electric push rod 411, the arc-shaped smearing plate 412 fits against the inner wall of the cutting ring 110, and the output end of the motor 414 drives the first gear 415 to rotate, causing the second gear 416 and the fifth electric push rod 409 as a whole to rotate. Thus, the vaseline on the arc-shaped smearing plate 412 is completely smeared on the inner wall of the cutting ring 110; Secondly, the output end of the transmission motor 226 drives the driving gear 227 to rotate, causing the driven gear 228 and the fixed cylinder 206 as a whole to rotate, driving the connecting frame 221 to rotate, and changing the originally horizontal cutting ring 110 to a vertical state, with the cutting ring 110 directly below the mounting plate 303; Next, the output end of the second servo motor 306 drives the second screw 304 to rotate, causing the two groups of second clamping members 307 to approach each other and clamp the top of the circumferential surface of the core cutter 110; then, the output end of the electric lifting rod 302 drives the clamped core cutter 110 to move downward and presses the core cutter 110 into the soil. It should be noted that the top of the circumferential surface of the core cutter 110 is wrapped by the second clamping members 307, so the above pressing operation cannot completely bury the core cutter 110 into the soil. At this time, the two groups of second clamping members 307 move away from each other to release the clamping of the core cutter 110. Secondly, the output end of the electric telescopic rod 309 extends, so that the hammering plate 310 is located below the middle of the mounting plate 303. Then, the output end of the electric lifting rod 302 drives the hammering plate 310 to move downward, and the hammering plate 310 hammers the top of the core cutter 110, so that the core cutter 110 is completely buried in the soil; After the core cutter 110 is completely buried in the soil, the output end of the first drive motor 503 drives the rotating plate 502 to rotate by an angle of ninety degrees. At this time, the seventh electric push rod 504 is directly above the center point of the core cutter 110. The output end of the eighth electric push rod 509 extends to drive the soil loosening knife 510 to move, so that the soil loosening knife 510 is directly above the soil at the outer edge of the core cutter 110. Secondly, the output end of the seventh electric push rod 504 drives the soil loosening knife 510 to move downward and completely penetrate into the soil. Then, the output end of the second drive motor 505 drives the drive wheel 506 to rotate. Driven by the belt 507, the driven wheel and the seventh electric push rod 504 rotate as a whole. Furthermore, the soil loosening knife 510 is in a rotating state to loosen the soil at the outer edge of the core cutter 110. Then, continue to control the extension of the output end of the eighth electric push rod 509 and repeat the above operation until a large area of the soil at the outer edge of the core cutter 110 is loosened; Continue to cooperate with the second servo motor 306 and the electric lifting rod 302 to make the two groups of second clamping members 307 clamp the top of the core cutter 110 and pull it out of the soil. After that, the two groups of first clamping members 225 in the clamping mechanism 2 approach each other and wrap around the outer wall of the core cutter 110. Under the action of the output end of the first stepping motor 204, the two groups of first clamping members 225 move up and down to scrape the soil on the outer wall of the core cutter 110; After that, the two groups of second clamping members 307 release the clamping of the core cutter 110, and the two groups of first clamping members 225 clamp the core cutter 110. Then, under the action of the output end of the second stepping motor 213, the two groups of first clamping members 225 move backward, driving the core cutter 110 to move backward. At this time, the right scraper 113 and the bottom wall of the core cutter 110 are in the same plane, and the left scraper 113 and the top wall of the core cutter 110 are in the same plane. Then, the output ends of the two groups of third electric push rods 112 extend, so that the two groups of scrapers 113 scrape the soil attached to the top wall and the bottom wall of the core cutter 110 respectively; Next, under the action of the output end of the second-step stepper motor 213, the two groups of first clamping members 225 continue to move backward, driving the core cutter 110 to continue moving backward until it reaches the top position of the high-temperature weighing device 108. Then, the output end of the air cylinder 601 drives the knocking head 602 to move to the left to knock on the outer wall of the core cutter 110, so that the annular soil inside the core cutter 110 is discharged and falls onto the high-temperature weighing device 108. The output end of the first electric push rod 105 contracts to drive the cover plate 104 to move, and the camera 103 takes a picture of the indicating meter 109. This indication is the mass of the wet soil. Secondly, the cover plate 104 resets and the sealing plate 107 blocks the front side of the drying oven 101, and the drying oven 101 starts to work to dry the annular soil. After that, the camera 103 takes a picture of the indicating meter 109 again, and this indication is the mass of the dry soil. Thus, the water content of the soil can be calculated. Moreover, the volume of the core cutter 110 is fixed. In the present invention, the volume of the core cutter 110 adopted is 200 cubic centimeters, so the wet density of the soil can be calculated. Based on the wet density and the water content, the dry density of the soil can be calculated. The whole process of the present invention automatically detects the soil without the need for staff to take soil, measure and calculate, which is convenient and fast and meets the needs of the staff.
