[0001] The present invention belongs to the technical field of soil detection, and specifically refers to a self-balancing and regulating soil quality detection device. Background Art

[0002] Soil quality detection is an important technical means in fields such as agriculture, environmental monitoring, and ecological restoration. In order to obtain real-time and accurate data on the physical, chemical, and biological characteristics of soil, soil detection devices with a pole insertion structure are widely used in in-situ soil monitoring. Such devices can insert sensor probes into the soil and, without damaging the soil structure, continuously monitor key parameters such as soil humidity, temperature, pH value, conductivity, nutrient content, and microbial activity for a long time.

[0003] In related technologies, soil detection devices with a pole insertion structure are widely used during soil detection due to their portable and simple structure. The core part is a detection pole installed at the bottom for inserting into the soil layer, and various sensors are integrated on the pole body. Although this design is simple and easy to use, in actual use, especially in complex and changeable soil layer environments and adverse weather conditions, such as when facing complex terrains like slopes and potholed ground or windy and rainy weather, the single pole insertion structure is difficult to maintain verticality and stability, and is prone to tilting or loosening, thereby affecting the accuracy of detection data.

The multiple balanced traction assemblies cooperate with each other to effectively realize the stable plug-in installation of the detection cylinder on the ground;

[0015] After the anti-drop insertion rod is inserted into the soil layer, the anti-drop deployment assembly distributed around its bottom can be driven by pressing the driving guide post, so as to deploy the soil layer clamping plates around the bottom of the housing, thereby increasing the overall grip of the annular traction seat and providing a stable traction force for the detection cylinder to ensure its installation stability;

[0016] The setting of the automatic locking and releasing assembly realizes the locking of the driving guide post after pressing and descending through the clamping connection of the fixed clip on the telescopic clamping plate to maintain the deployment of the soil layer clamping plate. The release clip will cooperate with the re-pressing and descending of the driving guide post. Through the cooperation of the lower inclined contact surface of the telescopic clamping plate and the release clip, the reset of the driving guide post is realized, and then the folding and retraction of the soil layer clamping plate are realized, so as to facilitate the extraction of the anti-drop insertion rod, providing convenience for the arrangement and recovery of the overall device, and the operation is simple;

[0017] The tension control assembly arranged around the control support base is connected to each anti - detachment insertion rod one by one through ropes and hooks. The tension control assembly composed of a ratchet, a wire reel, a limit clamping plate, etc. can cooperate with the annular traction base inclined at different angles according to different soil slopes to take in and release the ropes by different lengths, so as to ensure that the detection cylinder is vertically and stably inserted into the soil layer, and provide different tension effects around it to meet the requirements of different usage scenarios and provide guarantee for the detection of soil layer quality.

[0040] In an embodiment of the present invention, the balance pulling assembly 2 includes a pulling and regulating assembly 3, a rope 4 and a hook 5.

[0041] Among them, the pulling and regulating assembly 3 is distributed around the regulating support seat 41. The pulling and regulating assembly 3 includes a wire reel 42, a mounting seat 43, a positioning ratchet 44 and a limiting card plate 45. Among them, the wire reel 42 is rotatably connected to the mounting seat 43. A plurality of mounting seats 43 are provided and distributed around the regulating support seat 41.

The other end of the rope 4 is fixedly connected to the hook 5. The hook 5 is hooked to the traction opening 30.

[0042] In an embodiment of the present invention, the bottom of the detection cylinder 1 is a conical structure, and a detection insertion rod 7 is provided at the tip. The detection insertion rod 7 is internally provided with a soil detection sensor group. A support frustum 39 is provided at the bottom of the regulation support base 41. The regulation support base 41 is rotatably connected to the support frustum 39, and manipulation handles 40 are fixedly connected to both sides of the support frustum 39.

[0043] Working principle: When using a self-balancing regulation type soil quality detection device of the present invention for soil quality detection, relevant personnel first place the annular traction seat 49 on the ground centered on the specified detection soil layer. Then, relevant personnel insert the detection cylinder 1 into the specified soil layer through the manipulation handle 40 or in cooperation with relevant tools. The detection insertion rod 7 integrated with multiple sensors inside is inserted into the soil layer for data collection. Then, relevant personnel move the annular traction seat 49 to adjust its position to ensure that the detection cylinder 1 is located at its center. Then, relevant personnel can press or step on the annular traction seat 49 to completely insert the anti-drop insertion rods 6 distributed around it into the soil layer and make it firmly fit on the soil surface. To further ensure its tight connection with the soil layer, relevant personnel can step on the cover plate 31 on the anti-drop insertion rod 6 to press down the driving guide post 9 until the telescopic clamping plates 19 on both sides thereof pass through the fixed fixture 20 and enter the space between the fixed fixture 20 and the release fixture 22 after being extruded by the upper inclined surface, and stop pressing when a clicking sound is produced. At this time, under the action of the return spring 25, the upper surface of the telescopic clamping plate 19 is clamped with the bottom of the fixed fixture 20. At the same time, as the driving guide post 9 descends, the push block 11 pushes downward and drives the push rod 13 to rotate the soil layer clamping plate 14 in the surrounding expansion window 17 outward (the expansion angle is between 45 degrees and 90 degrees), thereby increasing the grip of the anti-drop insertion rod 6 on the soil layer and ensuring that the annular traction seat 49 is stably installed on the ground;

[0044] Immediately afterwards, relevant personnel can connect each traction regulation assembly 3 with each anti-drop insertion rod 6 through the balance traction assembly 2. Among them, relevant personnel lift the limit clamping plate 45 and release the positioning ratchet 44, thereby rotating the wire winding roller 42 to release the rope 4 until the hook 5 is hooked on the traction port 30 of the traction part 29 at the top of the driving guide post 9. Connect each anti-drop insertion rod 6 according to this operation sequence. Then, relevant personnel can tighten the rope 4 to different degrees according to the annular traction seat 49 on the inclined ground with different slopes. At this time, relevant personnel can drive the connecting rod 47 by rotating the handle 48 to drive the positioning ratchet 44 and the wire winding roller 42 to rotate synchronously to tighten the rope 4, and gradually adjust and tighten each surrounding traction regulation assembly 3 until it reaches stability, that is, the installation of the detection cylinder 1 is completed, realizing the regulation of the surroundings of the detection cylinder 1 according to different terrains to ensure that it is stably inserted into the specified soil layer for data collection.

[0045] It should be noted that different slopes will cause the annular towing seat 49 to form different tilting angles relative to the detection column 1. Therefore, the length of the rope 4 pulled will be different. The length of the rope 4 connected to the anti-drop plug 6 at the high point of the inclined surface is short, and vice versa. Moreover, the pulling force adjustment of the ropes 4 around needs to be gradual. Adjusting the traction force to the maximum at one time will cause the detection column 1 to tilt unilaterally.

[0046] It should be further noted that as Figure 2 and Figure 6 shown, when relevant personnel need to move the whole device out, especially when removing the anti-drop plug 6, they can press the cover plate 31 and the driving guide column 9 again so that the lower inclined contact surface 16 of the telescopic clamping plate 19 abuts against the inner edge of the upper surface of the release clip 22. After the telescopic clamping plate 19 contracts and slides below the release clip 22 and then expands, since the friction between the release clip 22 and the inner wall of the housing 8 is less than the friction of the telescopic clamping plate 19 on the lower inclined surface of the release clip 22, at this time, under the action of the return spring 25, the telescopic clamping plate 19 drives the release clip 22 to move upward until its upper surface coincides with and abuts against the lower surface of the fixed clip 20. At this time, one end of the telescopic clamping plate 19 contracts and rises under the sliding guidance of the lower inclined surface of the release clip 22 until it enters the inside of the fixed clip 20. At this time, the telescopic clamping plate 19 can expand and reset. At the same time, the anti-drop expansion assembly 10 resets and makes the expanded multiple soil layer clamping plates 14 rotate and close. At this time, relevant personnel can disassemble the balance pulling assembly 2 accordingly and disconnect it from the anti-drop plug 6.

[0047] Among them, relevant personnel can open a fillet at one end of the telescopic clamping plate 19 (i.e., the docking part of the lower inclined contact surface 16 and the upper surface of the telescopic clamping plate 19), so as to avoid the end of the telescopic clamping plate 19 being stuck with the lower inclined surface of the release clip 22 and unable to contract and reset when the release clip 22 abuts against the fixed clip 20 without affecting the telescopic clamping plate 19 driving the release clip 22 to move upward.

[0048] 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.
