[0002] When sampling agricultural and forestry soil, in order to ensure that the soil samples obtained meet the preset sampling depth, the sampling equipment must be perpendicular to the horizontal plane when drilling into the soil. Therefore, when sampling agricultural and forestry soil, the inclination of the sampling point needs to be measured in advance.

[0003] An invention patent with application number 202311510968.4 discloses an adjustable land slope measuring device, and specifically discloses the technical solution that "under the influence of gravity, the oil in the upper liquid pipe, rotating ring, lower liquid pipe and liquid collecting ball will be concentrated in the lower liquid pipe and the liquid collecting ball, so that the upper liquid pipe and the lower liquid pipe are in a vertical downward state. At this time, observe the indication scale of the pointer and record the data."

[0042] like Figure 1 to Figure 11 As shown, when the transposition electric push rod 702 is extended to the maximum length, the end face toothed disc 1 705 on the rotating end of the encoder 703 is meshed and connected with an end face toothed disc 2 706, supporting the electric push rod 707 to shrink to the minimum length and not contact the equipment box 2, and the upper buoy 4051 is abutted against the lower buoy 4052;

[0044] like Figure 1 to Figure 11 As shown, the equipment box 2 is provided with a sampling assembly 8, which includes an external leveling motor 801, a sampling platform 802, a sampling electric push rod 803, a notched sampling barrel 804, a lifting inclined plate 805, an inner closed door 806, a sampling opening and closing motor 807, a sampling drilling motor 808, a drill bit 809 and a closed ring 810. The external leveling motor 801 is fixedly arranged on the equipment box 2, the sampling platform 802 is fixedly arranged on the output end of the external leveling motor 801, the sampling electric push rod 803 is fixedly arranged on the sampling platform 802, and the notched sampling barrel 804 is fixedly arranged on the sampling At the bottom of the electric push rod 803, the lifting inclined plate 805 is fixed on the notch sampling barrel 804, the inner closed door 806 is rotatably arranged in the notch sampling barrel 804, the sampling opening and closing motor 807 is fixed in the notch sampling barrel 804, the output end of the sampling opening and closing motor 807 is fixedly connected to the inner closed door 806, the sampling drilling motor 808 is fixed below the notch sampling barrel 804, the drill bit 809 is fixed on the output end of the sampling drilling motor 808, the closing ring 810 is fixed on the drill bit 809, and the closing ring 810 is rotatably fitted below the notch sampling barrel 804.

[0045] like Figure 1 to Figure 11 As shown, a moving base 1 is fixedly provided at the bottom of the equipment box 2, and two towing hooks 101 are symmetrically provided on the moving base 1.

[0046] In specific use, when detecting the change in the slope of a certain section of land, the external vehicle is connected to the towing hook 101 by a rope, and the external vehicle drags the mobile seat 1 along the land through the rope and the towing hook 101 (at this time, the end face gear disc 1 705 on the rotating end of the encoder 703 is meshed and connected with an end face gear disc 2 706, so as to ensure that the encoder 703 can receive the slope change in real time, and the support electric push rod 707 is retracted to the minimum length and does not contact the equipment box 2. The synchronous sprocket unit 6 and the double-station measurement and re-inspection unit 7 have a tendency to fall in the absence of supporting force between the equipment box 2, so that the upper buoy 4051 abuts against the lower buoy 4052, and the lower buoy 4052 abuts against the floating plate 403). In the process of the mobile seat 1 moving along the land, the change in the slope of the land will be transmitted to the equipment box 2 through the mobile seat 1.

[0047] In the equipment box 2 pre-filled with liquid to obtain the internal horizontal reference liquid level, the floating plate 403 floats on the horizontal reference liquid level, the upper buoy 4051 is pressed against the lower buoy 4052, and the lower buoy 4052 is pressed against the floating plate 403, so that the two upper buoys 4051 can remain horizontal based on the horizontal reference liquid level. During the movement of the equipment box 2, the two upper buoys 4051 remain horizontal, the bottom of the equipment box 2 is parallel to the ground, and drives the guide column 404 to remain vertical to the ground.

[0048] When the land slope changes, the pitch angles of the two guide columns 404 relative to the horizontal plane also change, and drive the upper buoy 4051 to slide along the guide column 404. When the upper buoy 4051 slides along the guide column 404, the extension seat 501 rotating on the upper buoy 4051 synchronously changes its position in the equipment box 2. Since the two sides of the empty tube 503 are plug-connected with the two cross bars 502 respectively, when the two extension seats 501 adjust their positions, the empty tube 503 and the two cross bars 502 maintain the same inclination, and when the two upper buoys 4051 and the two extension seats 501 are horizontal, the empty tube 503 always maintains horizontality, and the center seat 504 always maintains verticality.

[0049] When the land slope changes, the equipment box 2 tilts synchronously, and the cooperation between the traction pin 6022 and the traction slot 6021 causes the H-shaped frame 602 to tilt synchronously. When the H-shaped frame 602 tilts, the chain 607 deflects as a whole, and at the same time, the fixed sprocket 603 is fixed on the center seat 504 by the locking pin 604, and there is relative rotation between the fixed sprocket 603 and the chain 607. The relative rotation between the fixed sprocket 603 and the chain 607 drives the chain 607 to operate, and further drives the moving sprocket 606 that rotates synchronously with the H-shaped frame 602 to rotate. The rotation of the moving sprocket 606 is transmitted to the encoder 703 through the upper synchronization shaft 605, the end face gear disc 2 706, and the end face gear disc 1 705. The encoder 703 records the change in the rotation angle of the moving sprocket 606 during the travel of the equipment box 2 and the mobile seat 1, and obtains the change in the land slope according to the specific transmission ratio between the moving sprocket 606 and the chain 607.

[0050] After the equipment box 2 and the moving seat 1 move, and the encoder 703 records and indicates the change of the slope, the supporting electric push rod 707 extends and abuts against the top of the equipment box 2, so that the synchronous sprocket unit 6, the center seat 504, the empty pipe 503, the cross bar 502, the extension seat 501 and the upper buoy 4051 below no longer fall, and suspend in the equipment box 2. At this time, the upper buoy 4051 is separated from the lower buoy 4052, and the lower buoy 4052 is still abutted against the floating plate 403 under the action of its own weight. The transposition electric push rod 702 shrinks to the minimum length, driving the long slide 701 to move, and at the same time, the end face toothed disc 1 705 on the rotating end of the encoder 703 is disconnected from the meshing connection with the end face toothed disc 2 706, and the end face toothed disc 1 705 on the output end of the inner motor 704 is meshed with the adjacent end face toothed disc 2 706.

[0051] Subsequently, the external vehicle drives the moving seat 1 to make a return movement. At the same time, the industrial computer 3 controls the inner motor 704 to work according to the angle change data of the encoder 703 during the previous travel process, so that at any point on the return journey, the inner motor 704 can drive the moving sprocket 606 to rotate through the end face gear disc 1 705, the end face gear disc 2 706, and the upper synchronous shaft 605. When the fixed sprocket 603 is fixed to the center seat 504 by the locking pin 604, the rotation of the moving sprocket 606 is transmitted through the chain 607 and acts on the fixed sprocket 603, the locking pin 604 and the center seat 504 at the same time, so that the H-shaped frame 602, the center seat 504 and the empty pipe 503 are deflected relative to the equipment box 2. Since at any time, the inner motor 704 outputs power according to the angle change data of the rotating end of the encoder 703 during the previous travel, the two upper buoys 4051 can maintain a theoretical horizontal state based on the angle change data during the previous travel through the transmission of the synchronous sprocket unit 6, the empty tube 503, the crossbar 502, and the extension seat 501. At this time, the two lower buoys 4052 and the floating plate 403 located below the two upper buoys 4051 also maintain a theoretical horizontal state based on the horizontal liquid surface during the return journey.

[0052] Without considering the impact of the bumpy land slope, the upper buoy 4051 and the lower buoy 4052 are relatively still, the small light source 4057 and the upper buoy 4051 remain fixed and still, the grating ruler 4055 and the lower buoy 4052 remain fixed and still through the ear plate 4054, the light beam emitted by the small light source 4057 and the grating ruler 4055 have no relative position change, and the photoelectric sensor 4058 cannot receive any light and dark change signal.

[0053] When the moving seat 1 and the equipment box 2 actually move on the land slope, obstacles on the land surface hinder the movement and cause the equipment box 2 to bump, affecting the stability of the horizontal liquid surface in the equipment box 2. At any point on the land slope, since the forward and return movement directions of the equipment box 2 are opposite, and the obstruction direction of the land surface is opposite, the front and rear bumps of the equipment box 2 are different, and the front and rear stability of the horizontal liquid surface in the equipment box 2 also has certain differences.

[0054] During the return journey of the mobile seat 1 and the equipment box 2, the floating plate 403 and the two lower buoys 4052 maintain theoretical level based on the liquid level, and have a slight deviation due to the bumps of the slope. According to the data recorded by the encoder 703 during the previous travel process, the inner motor 704 drives the two upper buoys 4051 to maintain theoretical level through the power transmission of the synchronous sprocket unit 6, the empty pipe 503, the crossbar 502, and the extension seat 501, and has a slight deviation due to the bumps of the slope.

[0055] Due to the bumpy slope, the upper buoy 4051 and the lower buoy 4052 move relative to each other. The relative movement between the upper buoy 4051 and the lower buoy 4052 drives the small light source 4057 and the grating ruler 4055 to move relative to each other, so that the relative position of the light beam emitted by the small light source 4057 and the grating ruler 4055 changes, and the photoelectric sensor 4058 receives the light and dark change signal, and indicates the relative displacement of the upper buoy 4051 and the lower buoy 4052 according to the number of light and dark changes, and feeds back to the industrial computer 3, so as to achieve the effect of evaluating the deviation between the horizontal liquid surface and the theoretical horizontal surface during the previous travel of the mobile seat 1 and the equipment box 2, and evaluating the reliability of the land slope detection data during the previous travel, and at the same time, achieving the effect of evaluating the degree of bumpy land slope.

[0056] During the return journey, in the road section where the bumpy slope measured by the small light source 4057, the grating ruler 4055, the photoelectric sensor 4058 and the industrial computer 3 has a small impact (i.e., the slope angle measured during the first process is more accurate), the external leveling motor 801 levels the sampling platform 802 according to the measured slope angle, and then the sampling electric push rod 803 extends, and the sampling drilling motor 808 drives the drill bit 809 to rotate, so that the notched sampling barrel 804 vertically enters the soil and reaches the desired soil layer depth. After the sampling depth is met, the sampling opening and closing motor 807 drives the inner closing door 806 to rotate, exposing the sampling notch of the notched sampling barrel 804. During the contraction of the sampling electric push rod 803, the lifting inclined plate 805 scrapes the soil, so that the soil of the desired depth enters the notched sampling barrel 804.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
