Description

[0002] With the wide promotion of the comprehensive land improvement project, scientifically and accurately grasping the physical and chemical properties of soils at different depths in each plot has become an important prerequisite for improving the improvement effect. Traditional soil detection methods mostly adopt manual drilling sampling and submission for analysis, which not only have a long cycle and large errors, but also are difficult to flexibly control the sampling depth and density, and cannot reflect the soil state changes in real time, bringing great limitations to the zoning planning and effect evaluation in the comprehensive improvement process;

[0003] Although some traditional multi-parameter soil collection devices can deploy multiple sensing nodes, most of the devices have a single detection depth and fixed deployment. However, at the site of comprehensive land improvement, the soil types are complex and changeable, and the soil parameters at different plots and different depths often have significant differences.

[0087] The layered sensing pile 30 is supported and positioned along the vertical direction of the connecting pile 15 by a plurality of the guiding buckles 40. The layered sensing pile 30 includes three layers of node piles:

[0088] A shallow sensing node pile 301, a middle sensing node pile 302 and a deep sensing node pile 303;

[0089] The shallow sensing node pile 301, the middle sensing node pile 302 and the deep sensing node pile 303 are assembled and arranged in sequence from top to bottom;

[0090] Among them, the upper end of the shallow sensing node pile 301 is fixedly connected to the lower buckle position of the guiding buckle 40 for installing the connecting pile 15;

[0091] A corresponding micro sensing unit 50 and a multi-point data driving mechanism 60 are respectively installed on each node pile of the layered sensing pile 30, where:

[0092] The micro sensing unit 50 is used to collect the humidity, conductivity, organic matter, particle distribution and temperature parameters of each soil layer;

[0093] Each of the micro sensing units 50 includes:

[0094] An integrated tube 51, eccentrically sleeved outside the node pile of the layered sensing pile 30;

[0095] Four mounting brackets 52, uniformly fixedly connected to the circumferential distribution position outside the integrated tube 51;

[0096] Five groups of sensors, respectively including: a near-infrared reflection sensor 53, a soil temperature sensor 54, a soil humidity sensor 55, a soil conductivity sensor 56 and an ultrasonic particle detection sensor 57;

[0097] Among them, the near-infrared reflection sensor 53, the soil temperature sensor 54, the soil conductivity sensor 56 and the ultrasonic particle detection sensor 57 are respectively installed on both sides of each mounting bracket 52 in a diagonal manner;

[0098] The soil humidity sensor 55 is installed on the outer wall of each mounting bracket 52;

[0099] A plurality of the micro sensing units 50 are arranged in layers along the layered sensing pile 30 for synchronously collecting various soil parameter information of the corresponding soil layers.

[0100] The multi-point data driving mechanism 60 is used to drive the corresponding micro sensing unit 50 to perform reciprocating acquisition operations within the length range of the node pile, and transmit the acquired multi-point data to the ground host 20;

[0101] Each of the multi-point data driving mechanisms 60 includes:

[0102] A biaxial combined motor 61, arranged with the two axes at a right angle, is respectively used to output rotational power in the vertical and longitudinal directions;

[0103] A rotating gear 62 is fixedly connected to the vertical output shaft of the biaxial combined motor 61;

[0104] A secondary gear 63 meshes with the rotating gear 62, and the inner wall of the secondary gear 63 is fixedly connected to the upper part of the outer wall of the integrated pipe 51;

[0105] A moving gear 64 is fixedly connected to the longitudinal output shaft of the biaxial combined motor 61;

[0106] A rack 66 is fixedly connected to the outer side wall of the node pile of the layered sensing pile 30 and is located in an eccentrically arranged area, and is meshed and connected with the moving gear 64;

[0107] A support 65, and the moving gear 64 is rotatably installed in the support 65 through a bearing;

[0108] Limit sliding grooves 67 are opened on both sides of the rack 66, and the guiding slider 68 is fixedly connected to the support 65 and is slidably matched with the limit sliding grooves 67 for defining the axial linear movement track of the rack 66.

[0109] The lifting driving mechanism 10 is used to support the layered sensing pile 30 and slightly lift it in the vertical direction through the driving connection pile 15 to adjust the position of the layered sensing pile 30 in the detection area, so that the detection point position of the micro sensing unit 50 is adjustable rather than fixed;

[0110] In this embodiment, a guiding taper rod 31 is screwed to the lower end of the deep sensing node pile 303. The front end of the guiding taper rod 31 is in a conical structure, which is used to play a guiding role when the layered sensing pile 30 is inserted into the soil, reduce the insertion force, and ensure that the layered sensing pile 30 can be inserted to the target depth area and fixed.

[0111] In this embodiment, the model of the biaxial combined motor 61 is: Redworth type.

[0112] When the present invention is in operation: Before the device is deployed, overall initialization of the equipment is performed. The ground host 20 is powered on and started through the power supply module, the main control unit enters the standby state, the pluggable data recording bin 21 completes no-load initialization, confirms that the data bin connection is stable, and the wireless communication receiver 22 starts the self-check mode to prepare for receiving real-time data transmitted by the subsequent micro-sensing unit 50 and the multi-point data driving mechanism 60.

[0113] When the lifting drive mechanism 10 is preparing for work, the lifting cylinder 14 contracts, driving the connecting pile 15 to the lowest initial position to facilitate the subsequent installation operation of the layered sensing pile 30.

[0114] When installing the layered sensing pile 30, prepare each node pile component, including the shallow-layer sensing node pile 301, the middle-layer sensing node pile 302, and the deep-layer sensing node pile 303. Each node pile has been pre-assembled with the corresponding micro-sensing unit 50 and multi-point data driving mechanism 60 to ensure that the sensing and acquisition functions are complete and error-free.

[0115] In the specific installation process, first take out the shallow-layer sensing node pile 301, align the upper end of its pile body with the lower buckle position of the first guiding buckle 40 initially set on the ground, and perform preliminary cooperation with the guiding buckle 40 by insertion. After the insertion is completed, tighten the threaded nuts 45 on the four fixing rods 41 to achieve axial locking of the limit seat 42. At the same time, tighten the limit nut 46 outside the fixed seat 43 to ensure that the shallow-layer sensing node pile 301 is firmly limited inside the guiding buckle 40, avoiding axial sliding or shaking during subsequent minor lifting or the working process of the node pile.

[0116] After the shallow-layer sensing node pile 301 is fixed, take out the middle-layer sensing node pile 302 and dock its lower end with the upper end of the shallow-layer sensing node pile 301. After the docking is completed, also set a new guiding buckle 40 at the node connection. According to the above steps, tighten the limit seat 42 with the threaded nut 45 and limit the fixed seat 43 with the limit nut 46 to achieve reliable connection and overall fixation between the middle-layer sensing node pile 302 and the shallow-layer sensing node pile 301.

[0117] And so on, continue to take out the deep-layer sensing node pile 303, dock it with the middle-layer sensing node pile 302, and complete the installation and locking fixation of the corresponding guiding buckle 40. Ensure that the node connection order of the entire layered sensing pile 30 is correct from top to bottom, each connection node is stably supported by the limiting structure of the guiding buckle 40, and the locking structure of each section has been tightened and verified to ensure that the overall pile body is in a continuous straight line state without obvious deviation, looseness, or structural deformation.

[0118] After the entire node pile is assembled, the lifting drive mechanism 10 is initially triggered by the ground host 20, and the connecting pile 15 and the layered sensing piles 30 it supports are inserted into the pre-drilled ground surface at a low speed. During the insertion process, the operator gradually controls the descending amplitude of the connecting pile 15 according to the depth prompt on the display interface of the ground host 20, ensuring that the shallow sensing node pile 301, the middle sensing node pile 302, and the deep sensing node pile 303 are respectively located in the preset tillage layer, silt layer, and basal layer soil areas, thereby realizing the preliminary layout of synchronous detection of multiple soil layers;

[0119] During the entire installation process, the guiding buckle 40 not only provides support and positioning between the node piles, but also realizes double-limiting of the axial and radial directions of the node piles through the threaded cap 45 and the limit nut 46, ensuring good stability and anti-disturbance ability of the layered sensing pile 30 during subsequent lifting and micro-movement from a structural perspective;

[0120] When the layered sensing pile 30 is stably inserted into the ground surface and reaches the predetermined working depth, the micro sensing unit 50 starts the initialization detection program. Each micro sensing unit 50 respectively collects the basic parameters of soil humidity, electrical conductivity, organic matter content, particle distribution, and temperature of the corresponding soil layer through the integrated near-infrared reflection sensor 53, soil temperature sensor 54, soil humidity sensor 55, soil electrical conductivity sensor 56, and ultrasonic particle detection sensor 57;

[0121] After receiving the start command, the multi-point data drive mechanism 60 starts to work. The dual-axis combined motor 61 drives the rotating gear 62 to rotate through the vertical output shaft of the dual-axis combined motor 61. Through the meshing transmission of the secondary gear 63, it drives the integrated pipe 51 to rotate circumferentially, thereby realizing soil collection in different horizontal azimuths by the micro sensing unit 50. Synchronously, the longitudinal output shaft of the dual-axis combined motor 61 drives the moving gear 64 to rotate, meshing and pushing the rack 66 to reciprocate along the length direction of the node pile. Through the coordinated action of the support 65, the limit chute 67, and the guiding slider 68, it ensures that the micro sensing unit 50 performs multi-point detection along the linear movement trajectory of the node pile axis, guaranteeing the stability of the collection path and the measurement accuracy;

[0122] Within a detection cycle, the micro sensing unit 50 first completes the preliminary data collection at the starting position; subsequently, the moving gear 64 drives the rack 66 to move slightly downward, and the micro sensing unit 50 moves to the next detection point to continue data collection. This process repeats until the data collection of multiple preset sampling points within the entire length range of the node pile is completed;

[0123] The multi-level and multi-point soil data collected are transmitted back to the ground host 20 in real time via the wireless communication receiver 22. The main control unit analyzes and processes the collected data and stores it in the pluggable data recording bin 21. The display screen synchronously and real-timely displays the change curves and layered distribution characteristics of the corresponding parameters of each node pile and each sensor, so as to provide the operator with an intuitive view of the current soil state;

[0124] To further improve the detection coverage density and resolution, the lifting drive mechanism 10 realizes the fine adjustment of the overall lifting of the connecting pile 15 and the layered sensing pile 30 in the vertical direction by controlling the micro-expansion and contraction of the lifting cylinder 14. Through the micro-position change, the micro-sensing unit 50 re-performs the reciprocating collection operation at the new position, so as to cover more vertical soil detail information. After each lifting adjustment, the multi-point data drive mechanism 60 resets to zero again to ensure the consistency of the starting point of each collection and ensure the continuity and comparability of the data;

[0125] After the set number of sampling times or when the coverage area requirement is met, the main control unit issues a collection stop instruction, and each micro-sensing unit 50 and the multi-point data drive mechanism 60 complete the shutdown. The lifting drive mechanism 10 drives the connecting pile 15 and the layered sensing pile 30 to slowly lift out of the ground surface, and the whole device exits the detection area;

[0126] Subsequently, the operator can extract the complete collected data through the pluggable data recording bin 21 on the ground host 20 and import it into the subsequent analysis platform for comprehensive processing.

[0127] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
