[0028] In one embodiment of the present invention, the balancing pulling assembly 2 includes a pulling regulating assembly 3 , a rope 4 and a hook 5 .

[0029] The pulling and regulating assembly 3 is distributed around the regulating support seat 41, and the pulling and regulating assembly 3 includes a take-up roller 42, a mounting seat 43, a positioning ratchet 44 and a limit clamp 45, wherein the take-up roller 42 is rotatably connected to the mounting seat 43, and a plurality of mounting seats 43 are provided and distributed around the regulating support seat 41, and the positioning ratchet 44 is rotatably arranged on one side of the mounting seat 43, and the positioning ratchet 44 is coaxially fixedly connected to the take-up roller 42, and the axis of the positioning ratchet 44 is connected to a connecting rod 47, a rotating handle 48 is provided at one end of the connecting rod 47, a limiting clamping plate 45 is provided above the positioning ratchet 44, one end of the limiting clamping plate 45 is rotatably connected to the surface of the mounting seat 43, and a clamping tooth 46 is provided on the lower surface of the other end of the limiting clamping plate 45.

[0030] In one embodiment of the present invention, the bottom of the detection column 1 is a conical structure and a detection rod 7 is arranged at the tip. The detection rod 7 has a built-in soil detection sensor group. A support table 39 is arranged at the bottom of the adjustment support seat 41. The adjustment support seat 41 is rotatably connected to the support table 39, and control handles 40 are fixedly connected to both sides of the support table 39.

[0031] Working principle: When using a self-balancing and controllable soil quality detection device of the present invention to detect soil quality, the relevant personnel first place the annular traction seat 49 on the ground with the designated detection soil layer as the center, and then the relevant personnel insert the detection column 1 into the designated soil layer by operating the handle 40 or cooperating with relevant tools, and insert the detection rod 7 with multiple sensors integrated inside into the soil layer for data collection, and then the relevant personnel move the annular traction seat 49 to adjust its position to ensure that the detection column 1 is located at its center, and then the relevant personnel can press or step on the annular traction seat 49 to facilitate the anti-falling rods 6 distributed around it to be completely inserted into the soil layer and firmly fit the surface of the soil layer, in order to further ensure its connection with the soil layer. The relevant personnel can step on the cover plate 31 on the anti-dropping plug rod 6 to press the driving guide column 9 downward until the telescopic card plates 19 on both sides pass through the fixed card member 20 and enter the space between the fixed card member 20 and the release card member 22 after being squeezed by the upper inclined surface, and the pressing can be stopped with a click. At this time, under the action of the reset spring 25, the upper surface of the telescopic card plate 19 is clamped with the bottom of the fixed card member 20. At the same time, as the driving guide column 9 descends, the push block 11 pushes downward and pushes the push rod 13 to rotate the soil card plates 14 in the surrounding expansion windows 17 outward (the expansion angle is between 45 degrees and 90 degrees), thereby increasing the grip of the anti-dropping plug rod 6 on the soil layer and ensuring that the annular traction seat 49 is firmly installed on the ground; Then, the relevant personnel can connect each pulling and regulating component 3 with each anti-falling plug rod 6 through the balanced pulling component 2, wherein the relevant personnel lifts the limit card plate 45 and releases the positioning ratchet 44, thereby rotating the take-up roller 42 to release the rope 4 until the hook 5 is hung on the traction port 30 of the traction part 29 at the top of the driving guide column 9, and connect each anti-falling plug rod 6 in this operation sequence, and then the relevant personnel can tighten the rope 4 to different degrees according to the inclined ground of the annular traction seat 49 with different slopes. At this time, the relevant personnel can drive the connecting rod 47 by turning the handle 48 to drive the positioning ratchet 44 and the take-up roller 42 to rotate synchronously to tighten the rope 4, and gradually adjust and tighten the pulling and regulating components 3 around it until it reaches stability, that is, the installation of the detection column 1 is completed, so as to realize the regulation of the detection column 1 around according to the different terrains to ensure that it is inserted into the designated soil layer in a balanced and stable manner for data collection.

[0032] It should be noted that different slopes will cause the annular traction seat 49 to form different inclination angles relative to the detection column 1, which will cause the length of the rope 4 to be pulled to be different. The rope 4 defense line connected to the anti-fall plug 6 located at the high point of the inclined surface is short, and vice versa. In addition, the pulling force adjustment of the rope 4 around it needs to be gradual, and the traction force cannot be adjusted to the maximum at one time, which will cause the detection column 1 to tilt on one side.

[0033] It needs to be further explained that if Figure 2 and Figure 6 As shown, when the relevant personnel need to remove the device as a whole, especially when removing the anti-dropping plug rod 6, they can press the cover plate 31 and the driving guide column 9 again to make the lower inclined contact surface 16 of the telescopic card plate 19 abut against the inner edge of the upper surface of the release card 22, and the telescopic card plate 19 shrinks and slides to the bottom of the release card 22 and then unfolds. Because the friction between the release card 22 and the inner side of the shell 8 is smaller than the friction between the telescopic card plate 19 and the lower inclined surface of the release card 22, the telescopic card 19 is released under the action of the reset spring 25. The plate 19 drives the release card 22 to move upward until its upper surface coincides with and abuts against the lower surface of the fixed card 20. At this time, one end of the telescopic card 19 shrinks and rises under the sliding guidance of the lower inclined surface of the release card 22 until it enters the inner side of the fixed card 20. At this time, the telescopic card 19 can be unfolded and reset. At the same time, the anti-falling unfolding assembly 10 is reset and the unfolded multiple soil layer cards 14 are rotated and closed. At this time, the relevant personnel can disassemble the balancing pulling assembly 2 accordingly and disconnect it from the anti-falling plug rod 6.

[0034] Among them, relevant personnel can open a rounded corner at one end of the telescopic card plate 19 (i.e., the place where the lower inclined contact surface 16 and the upper surface of the telescopic card plate 19 meet), so as to avoid the end of the telescopic card plate 19 being stuck with the lower inclined surface of the release card 22 when the release card 22 abuts against the fixed card 20, making it impossible to retract and reset, without affecting the telescopic card plate 19 driving the release card 22 to move upward.

[0035] In summary, the self-balancing and controllable soil quality detection device of the present invention connects the annular traction seat fixed on the ground with the control support seat on the detection column through a balanced pulling component. The anti-dropping plug rod distributed at the bottom of the annular traction seat cooperates with it to provide downward traction force around the detection column. Multiple balanced pulling components cooperate with each other to effectively realize the stable plug-in installation of the detection column on the ground. After being inserted into the soil layer, the anti-dropping plug rod can drive the anti-dropping deployment components distributed around its bottom by pressing the driving guide column, thereby expanding the soil layer clamping plates around the bottom of the shell, thereby increasing the overall grip of the annular traction seat, providing a stable pulling force for the detection column, and ensuring its installation stability. The automatic locking and releasing assembly is set up, and the driving guide column is locked after being pressed down by fixing the clamping part on the telescopic card plate, so as to maintain the expansion of the soil card plate, and the release card will cooperate with the driving guide column to be pressed down again, and the driving guide column is reset through the cooperation of the lower inclined contact surface of the telescopic card plate and the release card, so as to realize the folding and retraction of the soil card plate, so as to pull out the anti-falling plug rod, provide convenience for the arrangement and recovery of the whole device, and simple operation. The pulling and regulating assembly arranged around the regulating support seat is connected to each anti-falling plug rod one by one through ropes and hooks, and the pulling and regulating assembly composed of ratchets, winding rollers and limit cards can be used according to the different slopes of the soil layer to cooperate with the annular traction seat inclined at different angles, and the rope can be retracted and released at different lengths to ensure that the detection column is vertically and stably inserted into the soil layer, and provide different pulling effects around it to meet the needs of different usage scenarios and provide guarantee for the detection of soil quality.
