Description

Technical Field

[0001] This utility model relates to the field of farmland soil testing technology, specifically to a farmland soil testing device. Background Technology

[0002] Existing farmland soil testing equipment is mainly divided into two categories: portable field testing devices and fixed long-term monitoring systems. Most existing portable devices use borehole sampling, which involves a mechanical drill bit penetrating vertically to the target depth to collect a soil sample from a single location, followed by laboratory analysis or rapid on-site testing. This method has significant drawbacks, including: 1. The drilling process damages the original soil structure, affecting the accuracy of the test data; 2. Single-point sampling cannot reflect the gradient changes in soil parameters across the lateral range of the testing area, resulting in insufficient data representativeness; 3. Repeated testing requires multiple drilling operations, leading to low operational efficiency and high labor costs.

[0003] While fixed long-term monitoring systems achieve continuous data acquisition through pre-embedded sensor networks, they exhibit the following limitations in practical applications: First, the spatial layout and detection dimensions of the sensor array are determined during initial installation, making it impossible to adjust the position or expand the detection direction according to crop growth cycles or changes in the soil environment; Second, the functions of the sensor modules are fixed, making it difficult to address the differentiated detection needs of different soil types by changing combinations.

[0004] Therefore, existing soil testing equipment suffers from problems such as damaging soil structure, being unable to perform multi-dimensional horizontal testing, having a single testing dimension, and being insufficiently adaptable to long-term monitoring. Utility Model Content

[0005] The purpose of this utility model is to provide a soil testing device for farmland, so as to solve the technical problems of existing soil testing devices, which both damage the soil structure and cannot achieve multi-dimensional horizontal detection, as well as the single detection dimension and insufficient adaptability for long-term monitoring.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A soil testing device for farmland includes a hollow main body, on which a plurality of transverse inserts are equally spaced. One end of each transverse insert is connected to the hollow main body via a rotating component. The hollow main body has an installation slot that mates with the transverse insert. The rotating component allows the transverse insert to rotate around the rotating component to a radial direction along the hollow main body. A third through hole is provided on the surface of the hollow main body opposite the transverse insert.

[0008] The horizontal insert includes a shovel-shaped body, one end of which is provided with a hollow plug tube.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 4 As shown, this utility model provides a soil testing device for farmland, including a hollow main pole 1. Multiple transverse inserts 2 are evenly spaced on the hollow main pole 1. One end of each transverse insert 2 is connected to the hollow main pole 1 via a rotating component 3. An installation slot 4 is provided on the hollow main pole 1 to cooperate with the transverse insert 2. The rotating component 3 allows the transverse insert 2 to rotate around the rotating component 3 to the radial direction of the hollow main pole 1. A third through hole 7 is provided on the surface of the hollow main pole facing the transverse insert 2.

[0032] The horizontal insert 2 includes a shovel-shaped body 21, one end of which is provided with a hollow plug tube 22. The connection between the shovel-shaped body 21 and the hollow plug tube 22 is rotatably connected to the hollow main rod 1. The hollow plug tube 22 is rotatably connected to the rotating part 3. A spline 23 is provided inside the end of the hollow plug tube 22. A through hole 24 is formed at the end of the shovel-shaped body 21 near the hollow plug tube 22.

[0033] A mating body 25 is provided on the concave side surface of the shovel-shaped body 21. An inclined surface 26 is provided on the mating body 25. The edge of the inclined surface 26 is combined with the edge of the concave side surface of the shovel-shaped body 21. A plurality of first through holes 27 for installing sensors are provided on the mating body 25. The first through holes 27 extend from the surface of the inclined surface 26 to the end of the shovel-shaped body 21 near the hollow plug tube 22.

[0034] This invention utilizes a hollow main rod 1 fixedly inserted into the soil. When inserting the hollow main rod 1 into the target soil location, a right-angled triangular groove is cut in the soil. The hollow main rod 1 serves as the vertical right-angle side of the right-angled triangular groove. The hollow main rod 1 is opened by rotating the horizontal plug 2 to a position perpendicular to the hollow main rod 1. Initially, the hollow main rod 1 is rotated to the hypotenuse position of the right-angled triangular groove, with the bottom of the hollow main rod 1 as the rotation point. This allows the hollow main rod 1 to rotate closer to the vertical right-angle side and insert the horizontal plug 2. In this way, without disrupting the vertical distribution of the soil, the horizontal plug 2 extends and sets the sensor in the horizontal soil of the detection position, achieving horizontal detection of the soil.

[0035] Then the ratchet wrench connects to the spline 23 of the hollow plug tube 22 through the third through hole 7, and then rotates the shovel-shaped body 21 so that the inclined surface 26 of the mating body 25 on the shovel-shaped body 21 contacts the soil. In this embodiment, the mating body 25 can be made of hollow hard sponge material.

[0036] This utility model consists of only a hollow main pole 1 and an equipment mounting platform 5 on the hollow main pole 1. The equipment mounting platform 5 can be used to install a controller or host, and the sensor is electrically connected to the mating body 25. Furthermore, the horizontal plug 2 can be folded and stored with the hollow main pole 1, making the overall appearance and structure simple and portable.

[0037] This invention enables the replacement of sensors and adjustment of the monitoring direction of the horizontal plug-in 2 when the soil at the monitoring site is damaged by the horizontal plug-in 2, thereby obtaining various forms of soil detection.

[0038] To illustrate that the rotating component 3 provides rotation for the shovel-shaped body 21, a specific embodiment of the rotating component 3 is provided, including a sleeve seat 31 fitted onto the hollow plug tube 22. A connector 32 is provided on the top of the sleeve seat 31, and the connector 32 is rotatably connected to the sleeve seat 31. A guide seat 33 is provided on the inner wall of the hollow main rod 1, and the guide seat 33 is arranged along the axial direction of the hollow main rod 1. The guide seat 33 is located above the connection between the shovel-shaped body 21 and the hollow plug tube 22. The other end of the connector 32 is connected to the guide seat 33, and the guide seat 33 allows the end of the connector 32 to move axially along the hollow main rod 1.

[0039] In soil testing, to ensure that soil samples are taken separately at each location of the transverse insert 2 and to avoid cross-testing, a longitudinal partition plate 11 is installed inside the hollow main body 1. Multiple transverse partition plates 12 are installed on the longitudinal partition plate 11 and connected to the inner wall of the hollow main body 1. The transverse partition plates 12 are located inside the hollow main body 1 above the guide seat 33. The purpose is to form a cavity within the hollow main body 1 at each location of the transverse insert 2. This cavity can collect soil parameters and properties at the corresponding bottom soil layer. For example, after the transverse insert 2 is inserted into the soil, the installation slot 4 is opened. Due to soil erosion and water infiltration, water or soil in the corresponding soil layer can easily enter the corresponding cavity. Then, samples of the water or soil in each cavity are collected from the top of the hollow main body 1.

[0040] A second through hole 13 is provided on the longitudinal partition plate 11 at the position corresponding to the rotating part 3. The second through hole 13 is sealed by a sealing plug. When necessary, the sealing plug is removed, and the hollow plug tube 22 is operated through the second through hole 13. For example, the shovel-shaped body 21 can be rotated by rotating the plug tube 22. Specifically, a ratchet wrench can be inserted into the spline 23 of the hollow plug tube 22 to rotate the shovel-shaped body 21 and adjust the angle of the inclined surface 26 of the mating body 25 in contact with the soil.

[0041] Insert the ratchet wrench from the top of the hollow main body 1 and insert it into the spline 23 through the second through hole 13.

[0042] An equipment mounting platform 5 is provided on the top of the hollow main rod 1. The equipment mounting platform is threadedly connected to the top of the hollow main rod 1. An assembly plate 7 is provided on the top of the hollow main rod 1, which mates with the top opening of the hollow main rod 1. A threaded hole is provided in the middle of the assembly plate 7, which is connected to the equipment mounting platform 5 through the threaded hole. The assembly plate 7 and the hollow main rod 1 are detachably connected. By disassembling the assembly plate 7, the transverse insert 2 can be operated through the second through hole 13 on the longitudinal partition plate 11.

[0043] For example, rotating the shovel-shaped body 21 and replacing the sensor in the first through hole 27 on the mating body 25. The sensor may specifically include a temperature sensor, a humidity sensor, a conductivity sensor, an NPK sensor, a pH sensor, and a moisture content sensor.

[0044] Furthermore, when the shovel-shaped main body 21 is inserted laterally into the soil, and soil testing is required at the insertion point, a clamping tool can be used to clamp the end of the hollow plug tube 22 through the second through hole 13 of the longitudinal partition plate 11. At this time, the sleeve seat 31 can move axially along the hollow plug tube 22. The edge of the concave side surface of the shovel-shaped main body 21 protrudes from the edge of the mating body 25 to form a convex edge 28. The convex edge 28 will scrape out a certain amount of soil through the installation slot 4 into the cavity formed by the longitudinal partition plate 11, the transverse partition plate 12, and the inner wall of the hollow main rod 1 where the current transverse plug 2 is located. Further, the soil corresponding to the current transverse plug 2 is sampled and tested by a sampling device or apparatus, which also enters the cavity through the second through hole 13.

[0045] Of course, at this time, the shovel-shaped body 21 can be rotated to a suitable position by using the spline 23 of the device, that is, the shovel-shaped body 21 rotates around the hollow plug tube 22.

[0046] To further explain, such as Figure 3 and Figure 4 As shown, in this embodiment, the connector 32 can specifically be two connecting rods, which are respectively disposed on both sides of the sleeve seat 31.

[0047] The space between the two connecting rods is consistent with the through hole 24. That is, when the shovel-shaped body 21 is rotated to a state perpendicular to the hollow main rod 1, the third through hole, the two connecting rods and the through hole 24 are consistent, so that the sensor in the first through hole 27 can be operated through the third through hole 6. The sensor probe extends to or out of the surface of the inclined surface 26.

[0048] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
