[0032] Referring to Figures 1 to 7 , a field sampling point positioning device, comprising a bottom plate, the bottom plate is horizontally arranged;

[0033] Further comprising a controller, a stand 1, a buffer mechanism and a positioning mechanism;

[0034] The buffer mechanism is arranged on the top of the bottom plate, and the buffer mechanism comprises a spherical hinge 2, a spherical hinge support 3 and four extension assemblies, the spherical hinge support 3 is fixedly arranged on the top of the bottom plate, the spherical hinge 2 is hingedly arranged on the top of the spherical hinge support 3, the stand 1 is fixedly arranged on the top of the spherical hinge 2, and the four extension assemblies are arranged at equal intervals between the stand 1 and the bottom plate;

[0035] The positioning mechanism is arranged on the top of the bottom plate, and comprises a driving motor 4, a conversion assembly, two rotating assemblies and four tapered stakes 5. The driving motor 4 is fixedly arranged on the top of the bottom plate. The two rotating assemblies are symmetrically arranged on the top of the bottom plate. The conversion assembly is arranged between the two rotating assemblies. The four tapered stakes 5 are slidingly arranged on the top of the bottom plate. The driving motor 4 is electrically connected with the controller.

[0036] Referring to Figures 1 to 7 As shown in the figure, each telescopic assembly comprises an inner rod 6, a sleeve rod 7 and a telescopic spring 8. The inner rod 6 is hingedly arranged on the outer wall of the vertical rod 1. Four hinged blocks are rotatably arranged on the top of the base. The sleeve rod 7 is hingedly arranged on the top of one of the hinged blocks. The inner rod 6 is slidingly connected with the sleeve rod 7. The end of the inner rod 6 close to the sleeve rod 7 is fixedly provided with an anti-disengagement block 9. A circular sliding hole is arranged on the inner wall of the inner rod 6 for the anti-disengagement block 9 to slide. The telescopic spring 8 is inserted into the circular sliding hole. The inner wall of the circular sliding hole and the outer wall of the anti-disengagement block 9 are respectively in contact with the two ends of the telescopic spring 8. When the vertical rod 1 is impacted by a transverse or longitudinal external force, the vertical rod 1 rotates in the opposite direction of the impact on the top of the spherical hinge support 3 through the spherical hinge 2. Since one end of the inner rod 6 is hinged with the vertical rod 1, the other end of the inner rod 6 is slidingly connected with the sleeve rod 7 through the anti-disengagement block 9. The end of the sleeve rod 7 away from the inner rod 6 is hinged with one of the hinged blocks. The bottom of each hinged block is rotatably connected with the top of the bottom plate. Thus, the inner rod 6 slides in the circular sliding hole in the sleeve rod 7 through the anti-disengagement block 9.

[0040] With reference to Figures 1 to 7 As shown, the bottom of each conical inserting rod 12 is provided with a plurality of cutting blades 20 at equal intervals, in the initial state, when the conical inserting rod 5 is vertically inserted into the ground, the plurality of cutting blades 20 cut the ground soil, reducing the resistance of the conical inserting rod 5 directly inserted into the ground, thereby being beneficial to improving the positioning efficiency and effect.

[0041] With reference to Figures 1 to 7The top of the vertical rod 1 is provided with a second rotating shaft, and the top end of the second rotating shaft is fixedly provided with a sampling head 21. The inside of the sampling head 21 is designed with a GPS positioning sensor, a wind speed sensor and a carbon dioxide sensor. The GPS positioning sensor can remotely and accurately position the real-time sampling position of the device. Based on the principle of micro-meteorology, the vertical wind speed and the pulsed covariance of the carbon dioxide concentration are measured by the wind speed sensor and the carbon dioxide sensor to directly calculate the carbon dioxide exchange between the ecosystem and the atmosphere. This method can provide high time resolution carbon flux data and is suitable for studying short-term carbon dynamic changes.

Since the worm gear 22 is fixedly connected with the second rotating shaft, and the sampling head 21 is rotatably connected with the vertical rod 1 through the second rotating shaft, the worm gear 22 is meshingly connected with the worm 23, thereby driving the sampling head 21 to rotate horizontally, covering a larger range of sample plots and avoiding sampling errors caused by repeated positioning. At the same time, the rotation realizes sampling in a circular or sector area, reduces local sample deviation, and improves the accuracy of sampling.
