The output end of the servo motor 14 is transmission-connected with a driving gear 16, and the outer side of the driving gear 16 is engaged with a driven gear ring 17. Three sliding frames 18 are fixedly installed on the inner wall of the support tube 1, and two of the three sliding frames 18 are slidably installed with a slide bar 19 inside. The top of the transparent sampling tube 13 is fixedly sleeved with an air outlet pipe 21, and a one-way valve 22 is installed inside the air outlet pipe 21. The outer side of the air outlet pipe 21 is threadedly sleeved with a sealing plugging cover 24. Four limit screws 25 are provided on the top of the support ring plate 11, and a number of air vents 23 are opened on the top of the transparent sampling tube 13. A control panel 3 is fixedly installed on the outer side of the support tube 1.

[0021] The working principle of the above technical solution is as follows: when in use, after connecting the external power supply, the user holds the handle 4 and starts the equipment so that the drill barrel 5 and the guide cone 6 dock with the top of the soil to be sampled, and then starts the servo motor 14 and the reduction motor 9. The rotation of the servo motor 14 drives the driving gear 16 to rotate, and the rotation of the driving gear 16 drives the drill barrel 5 to rotate through the driven gear ring 17. The drill barrel 5 maintains stable rotation under the support of the limit bearing 8 and the support shaft seat 2 20. After the reduction motor 9 rotates, it drives the screw rod 10 to rotate. Under the spiral transmission action of the screw rod 10 and the support ring plate 11, the support ring plate 11 is limited by the slide bar 15, the slide frame 18 and the slide bar 19 to maintain a stable position, thereby prompting the support ring plate 11 to move downward.

The soil moves up inside the transparent sampling barrel 13 and the air flow is discharged through the one-way valve 22 to form a negative pressure between the soil and the transparent sampling barrel 13, thereby stabilizing the position of the sampled soil. After the sampling is completed, the drill barrel 5 is pulled out. When the sample needs to be taken out, the movable cover 2 is opened, and the limit screw 25 is unscrewed to release the limit on the transparent sampling barrel 13, and the transparent sampling barrel 13 is pulled out from the inside of the drill barrel 5 and the inside of the movable cover 2. A new transparent sampling barrel 13 is replaced to continue the operation. The overall operation is convenient, avoiding the tediousness of pouring out the sample from the sampling barrel. The sample can be directly replaced, which increases the overall convenience of use.

[0022] In another embodiment, Figures 1-4 As shown, the specification size of the inner side of the guide cone 6 is consistent with the wall thickness of the transparent sampling tube 13, and the inner diameter of the guide cone 6 is adapted to the inner diameter of the transparent sampling tube 13.

[0023] The inner diameter of the guide cone 6 is slightly more convex than the inner side of the drill tube 5. In order to support the transparent sampling tube 13, and the size is consistent with the transparent sampling tube 13, it is convenient for sampling and increases stability. When taking out the sample, this solution unscrews the sealing plugging cover 24. At this time, the sealing plugging cover 24 releases the airtight limit on the air vent 23, and the air flow enters the interior of the transparent sampling tube 13 through the air vent 23, so that the negative pressure between the sample and the transparent sampling tube 13 is released, and the sample can be poured out. Moreover, due to the transparent effect of the transparent sampling tube 13, the specific shape and state of the sample can be intuitively observed when taking out the sample, which is convenient for assisting the operator to take samples and record, and is convenient for observation, further increasing the convenience of the operation.

[0024] In another embodiment, Figure 3 and Figure 4 As shown, the sliding rods 15 are evenly distributed in a circumferential manner inside the supporting ring plate 11 , and both ends of the sliding rods 15 are fixedly mounted on the inner wall of the support tube 1 .

[0025] The slide rod 15 provides a stabilizing force for the supporting ring plate 11 and increases the relative stability of the structure, thereby facilitating the maintenance of structural stability and increasing moment stability.

[0026] In another embodiment, Figure 3 As shown, the reduction motor 9 is fixedly installed on the top of the inner cavity of the support tube 1, and the support shaft seat 12 is fixedly installed on the bottom of the inner cavity of the support tube 1.

[0027] After being fixed, the reduction motor 9 drives the screw rod 10 to rotate, thereby cooperating with the screw rod 10 to apply a relatively stable threaded connection force to the support ring plate 11, so as to facilitate applying a moving action to the support ring plate 11.

[0028] In another embodiment, Figure 3 and Figure 4 As shown, the driven gear ring 17 is fixedly sleeved on the outside of the drill barrel 5, the opposite end of the slide bar 19 is fixedly installed on the outside of the drill barrel 5, the outside of the servo motor 14 is slidably installed on the inside of another slide frame 18 away from the slide bar 19 through a slider, the sleeve on the outside of the drill barrel 5 is movably sleeved with the drill barrel 5 through a bearing, and the sleeve on the outside of the servo motor 14 is fixedly sleeved with the servo motor 14.

[0029] The driven gear ring 17 is fixedly sleeved on the outside of the drill barrel 5 for easy transmission, and the outside of the drill barrel 5 is sleeved with a hoop through a bearing, so that the position of the servo motor 14 can be fixed by the hoop, so as to maintain the common up and down movement of the servo motor 14 and the drill barrel 5 without affecting the rotation of the drill barrel 5. As the hoop is fixed, the servo motor 14 will deflect due to the bearing on the inside of the hoop. At this time, the outside of the servo motor 14 is fixed to the inside of the slide frame 18 through a slider, thereby limiting the up and down movement of the servo motor 14, thereby stabilizing the overall operation, facilitating coordinated movement, and increasing the convenience of the structure.

[0030] In another embodiment, Figure 5 As shown, the top of the support ring plate 11 is hollow, the transparent sampling tube 13 is made of transparent material, and the four limit screws 25 are fixed to the top of the support ring plate 11 by nuts, and the limit screws 25 are threadedly connected through the nuts and extend to the inside of the sealing blocking cover 24. The specifications and dimensions of the sealing blocking cover 24 are compatible with the specifications and dimensions of the air vent 23. The sealing blocking cover 24 is sealed on the outside of the transparent sampling tube 13 and the air outlet pipe 21 through a sealing gasket, and the center of the top of the sealing blocking cover 24 is connected.

[0031] The hollowness of the support ring plate 11 facilitates the passing and removal of the transparent sampling tube 13. The nut on the outside of the limit screw 25 is fixed to the top of the support ring plate 11 and is threadedly connected to the inside of the sealing blocking cover 24, which is convenient for limiting the transparent sampling tube 13. Cooperating with the support of the guide cone 6, the position of the transparent sampling tube 13 is stabilized, and the sealing blocking cover 24 is prevented from slipping, further stabilizing the operation. The sealing blocking cover 24 seals the top of the transparent sampling tube 13 and the top of the air vent 23 through a sealing gasket, which facilitates the flow of air at a predetermined position, and when the sealing blocking cover 24 is released from limiting the air vent 23, the air flow enters the interior of the transparent sampling tube 13 through the air vent 23, which is convenient for balancing the air pressure and pouring out the sample.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
