Description

Technical Field

[0001] This utility model relates to the field of soil ecological data acquisition, specifically to a real-time soil ecological data acquisition instrument. Background Technology

[0002] Soil ecological data acquisition is a key link in soil science research, ecological environmental protection, and sustainable agricultural development. Its goal is to obtain multi-dimensional information on soil, including physical, chemical, and biological data, in order to comprehensively assess soil health. Soil ecological data acquisition instruments are professional devices used to monitor soil ecological parameters. They can achieve multi-dimensional data acquisition and remote management and have wide applications in agriculture, environmental monitoring, and other fields.

[0003] A search revealed a utility model patent with publication number CN212514568U, which discloses a soil ecological monitoring device. The device includes a detection vehicle body, a support mechanism mounted on the vehicle body, and a sampling mechanism mounted on the support mechanism and extending downwards through the vehicle body. The vehicle body includes a fixed base and a first sampling hole in the center of the fixed base. The support mechanism includes a lower rotating seat mounted on the fixed base, an electric cylinder rotatably connected to the lower rotating seat, and an upper rotating seat connected to the cylinder rod of the electric cylinder. The support mechanism also includes a T-shaped support seat extending through the first sampling hole, a second sampling hole in the center of the T-shaped support seat, and a sampling column inserted into the second sampling hole. This soil ecological monitoring device is easy to use and has high monitoring accuracy.

[0004] Existing soil data acquisition equipment involves drilling holes to sample the soil before analyzing the data. However, because these devices use rotating boreholes for sampling, soil from different soil layers enters the sampling equipment during the rotation process. This mixing of various soil types makes it impossible to accurately measure data from different depths of the soil layer, significantly reducing the accuracy of the soil data.

[0005] Therefore, it is necessary to invent a real-time soil ecological data acquisition instrument to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a real-time soil ecological data acquisition instrument. By rotating the connecting cylinder in both directions, the connecting cylinder can reach a designated location to collect soil, thus solving the problem in the prior art that it is impossible to accurately collect soil at the corresponding depth.

[0008] The pressing component located above the support platform includes slide rails, which are symmetrically installed in a cross shape above the support platform.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1-5 The soil ecological data real-time acquisition instrument shown includes a support platform 001, support legs 101 symmetrically installed below the support platform 001, and a drill bit 102 disposed below the support platform 001.

[0028] The support leg 101 supports the support platform 001, and the drill bit 102 can drill holes in the soil.

[0029] The pressing component 002, located above the support platform 001, includes a slide rail 201. The slide rails 201 are symmetrically installed in a cross shape above the support platform 001. Each of the two sets of symmetrical slide rails 201 is rotatably connected to a screw 202. Each of the two sets of slide rails 201 is equipped with a servo motor 203 on one side, and the output end of the servo motor 203 is shaft-connected to the corresponding screw 202.

[0030] The servo motor 203 can drive the screw 202 to rotate within the slide rail 201.

[0031] The power assembly 003 located above the support platform 001 includes a fixed cylinder 301, a servo motor 306 mounted on the fixed cylinder 301, an internal threaded cylinder 303 rotatably connected inside the fixed cylinder 301, and the internal threaded cylinder 303 is axially connected to the output end of the servo motor 306. A positioning plate 307 is sleeved and fixed on the top of the internal threaded cylinder 303.

[0032] The servo motor 306 can drive the internal threaded cylinder 303 to rotate.

[0033] The acquisition component 004 located below the fixed cylinder 301 includes a connecting cylinder 2 401. A fixing frame 407 is installed on the inner wall of the connecting cylinder 2 401, and the fixing frame 407 is internally connected to the internal threaded cylinder 303. A fixing ring 1 406 is sleeved and fixed on the internal threaded cylinder 303, and the fixing ring 1 406 is in contact with the upper part of the fixing frame 407. A fixing ring 2 409 is sleeved and fixed on the internal threaded cylinder 303, and the fixing ring 2 409 is located below the fixing frame 407. A spring 408 is sleeved on the internal threaded cylinder 303, and the two ends of the spring 408 are in contact with the lower part of the fixing frame 407 and the upper part of the fixing ring 2 409, respectively.

[0034] The spring 408 can be compressed by the fixed bracket 407 moving downward with the connecting cylinder 401, so that the spring 408 can play a buffering and restoring role.

[0035] Furthermore, in the above structure, the pressing component 002 also includes internal threaded blocks 204. Two sets of internal threaded blocks 204 are symmetrically screwed onto the corresponding screw 202. Slide rods 207 are installed in the other two sets of symmetrical slide rails 201. Slider blocks 208 are slidably connected to the two sets of slide rods 207.

[0036] The internal thread block 204 and the screw 202 work together so that the screw 202 can rotate and drive the internal thread block 204 to move, and the slider 208 can slide along the slider 207.

[0037] Furthermore, in the above structure, connecting arms 206 are rotatably connected above the two sets of sliders 208 and the internal thread block 204, and a connecting platform 205 is provided above the bearing platform 001. The connecting arms 206 are rotatably connected to the side of the connecting platform 205, and the connecting platform 205 is fixedly connected to the fixed cylinder 301.

[0038] The connecting arm 206 allows the connecting platform 205 to press down as the internal thread block 204 moves, and the slider 208 ensures that its downward movement is more stable.

[0039] Furthermore, in the above structure, the power assembly 003 also includes a connecting cylinder 302, which is connected to the inner limit of the connecting platform 205. The internal threaded cylinder 303 is also connected to the inner of the connecting cylinder 302. A controller 304 is symmetrically installed above the connecting cylinder 302. An electric actuator 305 is installed above each controller 304, and the output end of each set of electric actuators 305 is located on one side of the inner wall of the fixed cylinder 301.

[0040] The controller 304 can drive the electric actuator 305 to move, so that the output end of the electric actuator 305 fits against the inner wall of the fixed cylinder 301, thereby fixing the position of the connecting cylinder 302.

[0041] Furthermore, in the above structure, the acquisition component 004 also includes a limiting hole 402, which is arranged in a ring above the connecting cylinder 2 401. Multiple sets of limiting rods 403 are installed in a ring below the connecting cylinder 1 302, and the limiting rods 403 are slidably connected to the corresponding limiting holes 402. An acquisition cylinder 404 is installed on the inner wall of the connecting cylinder 1 302, and the acquisition cylinder 404 is connected through the connecting cylinder 2 401. Multiple sets of soil moisture sensors 405 are installed in a ring on the outer side of the acquisition cylinder 404.

[0042] The soil moisture sensor 405 can collect soil moisture data, and the space formed by the inner wall of the collection cylinder 404 and the connecting cylinder 302 can effectively collect soil. The cooperation between the limiting rod 403 and the limiting hole 402 can ensure that the connecting cylinder 401 moves in a limited position along the bottom of the connecting cylinder 302.

[0043] Furthermore, in the above structure, multiple sets of connecting cylinders 401 are installed sequentially below the connecting cylinder 401 in the same manner, and the length of the limiting rod 403 of the lower connecting cylinder 401 is successively longer than that of the upper connecting cylinder 401. The bottom connecting cylinder 401 is fixedly connected to the drill bit 102, and a screw rod 410 is installed on the inner wall of the bottom connecting cylinder 401, and the screw rod 410 is screwed into the internal thread cylinder 303.

[0044] By setting the length of the limiting rods 403 of the multiple sets of connecting cylinders 401 below the connecting cylinder 401, and cooperating with the screw 410, the internal thread cylinder 303 can push the screw 410 downward, thereby achieving the effect that each set of connecting cylinders 401 moves downward in sequence, and the connection of each set of connecting cylinders 401 gradually unfolds. The connecting platform 205 can reciprocate under the action of the servo motor 203, so that the collection cylinder 404 can collect soil. In addition, the internal thread cylinder 303 rotates in the opposite direction of the servo motor 306. The reverse rotation here refers to the direction of the engagement between the internal thread cylinder 303 and the screw 410. When rotating, it will not push the screw 410 to move. In this way, when the servo motor 306 rotates, it can drive each set of connecting cylinders 401 to rotate simultaneously, thereby making the drill bit 102 rotate.

[0045] The working principle of this practical application is as follows:

[0046] Refer to the instruction manual appendix Figures 1-5The reverse rotation of servo motor 306 causes all connecting cylinders 401 to rotate simultaneously, causing drill bit 102 to rotate. Simultaneously, servo motor 203 drives screw 202 to rotate, causing the internal thread block 204 to move downwards via connecting arm 206, moving connecting platform 205. Drill bit 102 then penetrates the soil. Once connecting cylinder 401 is fully inside the soil, controller 304 drives the output end of electric actuator 305 to contact the inner wall of fixed cylinder 301, thus limiting the position of connecting cylinder 401. Servo motor 306 then rotates forward, causing the internal thread cylinder 303 to push screw 410, continuously moving each connecting cylinder 401 downwards a certain distance. At this point, servo motor 203 also rotates in the reverse direction, gradually lifting connecting platform 205 upwards. To avoid the situation where connecting cylinder 2 401 moves downwards and lifts the entire device, and as connecting platform 205 gradually rises, the connecting cylinders 2 401 gradually unfold. During this lifting process, soil enters the collection cylinder 404, where the soil moisture sensor 405 can detect the moisture. The slight reciprocating movement of connecting platform 205 completes soil collection. After collection, the connecting cylinders 2 401 close, and the rising of connecting platform 205 removes the connecting cylinders 2 401 from the soil. This structure effectively allows the device to be inserted into the soil for collection without mixing in soil from different depths, thus ensuring the accuracy of collection and subsequent analysis. Furthermore, the overall structure is simple to operate, greatly improving the efficiency of soil data collection.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
