Description

Technical Field

[0001] The utility model belongs to the technical field of soil environment monitoring instruments, and in particular relates to an integrated soil environment monitoring instrument plug-in structure. Background Art

[0002] To monitor parameters such as soil moisture, temperature, and salinity in open fields, the traditional approach is to install multiple integrated soil monitors in the field and make comprehensive judgments by monitoring soil parameters at multiple points. The lower end of the integrated soil environmental monitor is buried in the soil, while the upper end must be exposed outside the soil. This will hinder various operations such as tillage and sowing at the location where it is buried, resulting in an uncultivated area in and around the location. This uncultivated area does not match the actual soil conditions, and over time, this will lead to a difference in shape between the uncultivated area and the actual soil, thus affecting crop growth. At the same time, the data collected by the integrated soil environmental monitor will be biased, seriously affecting the accuracy of the test. Furthermore, the integrated soil environmental monitor is relatively expensive, and the cost of using the environmental monitor remains high. Utility Model Content

[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides an integrated soil environment monitoring instrument plug-in structure to ensure that the soil in the pre-monitoring position can participate in the operation normally, ensure the consistency of the test environment, and improve the accuracy of relevant data such as environmental monitoring and crop growth. Multi-point environmental monitoring can be achieved by matching one upper tube with multiple lower tubes, thereby reducing the use cost of the environmental monitor.

[0004] The specific technical solution adopted in this utility model is:

[0005] A plug-in structure for an integrated soil environment monitor includes a lower tube buried in the soil. The key point is that it also includes an upper tube that is plugged into and matched with the lower tube. The lower tube is located below the tillage layer of the soil. The upper end of the lower tube is provided with an openable and closable sealing cap. The lower end of the lower tube is open. The sealing cap includes a group of petal-shaped spring pieces that are arranged in a ring array along the lower tube and are interlocked to form a convex bulge. The lower tube is provided with a lower sensor connected to the buried circuit. The upper tube is provided with an upper sensor and a power supply connected to the upper circuit. The lower end of the upper tube is inserted into the lower tube through the petal-shaped spring piece, and the buried circuit is connected to the upper circuit with the help of an electrical connection component. The upper sensor is provided in conjunction with the tillage layer.

[0006] An inverted skirt-shaped supporting plate is provided on the upper tube, and the supporting plate forms a lifting and resetting mechanism of the petal-shaped spring piece.

[0007] The upper end of the lower tube is also provided with a conical introduction port located above the sealing cap.

[0008] The electrical connection assembly includes a copper brush arranged on the lower tube and connected to the buried circuit and located below the sealing cap, and a copper wire arranged on the upper tube and connected to the upper circuit. The copper brush contacts the copper wire to connect the buried circuit with the upper circuit, thereby conducting the lower sensor and the upper sensor.

[0009] The lower tube is provided with a limiting platform which is located below the copper brush and matched with the lower end of the upper tube.

[0010] The beneficial effects of the utility model are:

[0011] The utility model adopts a technical solution of burying the lower tube below the tillage layer. When operating on the tillage layer, there is no need to avoid the position of the lower tube, so that the soil in the tillage layer above the buried position of the lower tube and the soil around the lower tube are consistent with the field soil; the sealing cap prevents the upper soil from falling into the lower tube, preventing the soil from affecting the insertion of the upper tube and the conduction of the circuit; the upper tube is inserted downward into the lower tube, and the petal-shaped spring is bent downward to open the upper end of the lower tube. Then the upper tube is further inserted downward so that the electrical connection component connects the buried circuit with the upper circuit, and the power supply is supplied to the lower sensor and the upper sensor. The upper sensor and the lower sensor can then perform environmental monitoring of the tillage layer and the soil below the tillage layer. The setting of the plug-in structure can realize multi-point environmental monitoring by only using one upper tube and multiple lower tubes, reducing the use cost of the environmental monitoring instrument, without affecting the operating range of the agricultural machinery on the soil, and improving the accuracy of the environmental monitoring data.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] Specific implementation examples Figure 1-5 As shown, an integrated soil environment monitoring instrument plug-in structure includes a lower tube 1 buried in the soil and an upper tube 2 plugged into and matched with the lower tube 1, the lower tube 1 is located below the tillage layer 3 of the soil, and the thickness of the tillage layer 3 is about 20 cm; the upper end of the lower tube 1 is provided with an openable and closable sealing cap 4, and the lower end of the lower tube 1 is open, and the sealing cap 4 includes a group of petal-shaped spring pieces 41 arranged in a ring array along the lower tube 1 and buckled together to form a convex bulge, the lower tube 1 is provided with a lower section sensor 7 connected to the buried circuit, the upper tube 2 is provided with an upper section sensor 9 and a power supply 10 connected to the upper circuit, the lower end of the upper tube 2 is in a conical structure, the lower end of the upper tube 2 is inserted into the lower tube 1 through the petal-shaped spring piece 41, and the buried circuit is connected to the upper circuit with the help of the electrical connection component, and the upper section sensor 9 is matched with the tillage layer 3.

[0020] The environmental monitor is inserted into the soil at a preset position and the lower tube 1 reaches a preset depth. The upper end of the lower tube 1 is located below the tillage layer 3. When operating on the tillage layer 3, the upper tube 2 can be removed to perform normal operations without having to avoid the position of the lower tube 1, so that the soil around the lower tube 1 and the tillage layer 3 above the lower tube 3 are consistent with the field soil; the sealing cap 4 prevents the upper soil from falling into the lower tube 1, preventing the soil from affecting the insertion of the upper tube 2 and the conduction of the circuit; when it is necessary to monitor soil parameters, the upper tube 2 is inserted downward to the top of the lower tube 1, and the upper tube 2 is continued to be pressed downward so that the lower end of the upper tube 2 contacts the petal-shaped spring piece 41 on the sealing cap 4. Under the downward pressure of the upper tube 2, the petal-shaped spring piece 41 bends downward, opening the upper end of the lower tube 1, and the upper tube 2 is continued to be inserted. The electrical connection component makes the buried circuit conductive with the upper circuit, and the power supply provides electrical energy to the lower sensor 7 and the upper sensor 9. The lower sensor 7 performs environmental monitoring on the soil below the tillage layer 3, and the upper sensor 9 performs environmental monitoring on the soil of the tillage layer 3.

[0021] The soil in the tillage layer 3 is relatively loose, making it easier to insert the upper tube 2. However, the soil below the tillage layer 3 is relatively hard, hindering the direct insertion of the upper tube 2. Therefore, the lower tube 1 is buried below the tillage layer 3. Once the upper tube 2 is inserted into the lower tube 1, the upper sensor 9 and the lower sensor 7 conduct electricity, allowing the upper and lower sensors 9 and 7 to monitor the soil at different depths and collect data. This plug-in structure is cost-effective and simpler, does not affect the operating range of the agricultural machinery, and improves the accuracy of environmental monitoring data.

[0022] The sealing cap 4 not only forms an arched support for the soil above during the non-monitoring period, but also effectively prevents leakage of the sealing cap 4 due to soil collapse by leveraging the soil's adhesive force. When the upper tube 2 is inserted into the lower tube 1, it carries a small amount of soil from the tillage layer 3. Therefore, after the upper tube 2 is repeatedly inserted 4-5 times, the soil in the lower tube 1 can be manually cleared to prevent excessive soil accumulation from affecting the connection of the electrical connection components.

[0023] Specifically, the electrical connection assembly includes a copper brush 8 disposed on the lower tube 1, connected to the underground circuit and located below the sealing cap 4, and a copper wire 11 disposed on the upper tube 2, connected to the upper circuit. The copper brush 8 contacts the copper wire 11, connecting the underground circuit to the upper circuit, thereby conducting the lower sensor 7 and the upper sensor 9. The copper brush 8 protrudes from the inner wall of the lower tube 1, and a groove is provided on the side wall of the upper tube 2. The copper wire 11 is located in the groove of the upper tube 2. When the upper tube 2 is inserted into the lower tube 1, the copper brush 8 is squeezed by the side wall of the upper tube 2. When the groove aligns with the copper brush 8, the copper brush 8 rebounds and extends into the groove, contacting the copper wire 11 and conducting electricity. At the same time, by rotating the upper tube 2 within the lower tube 1, the copper brush 8 can also brush the soil carried by the groove during the insertion of the upper tube 2, causing the soil in the groove to fall, preventing the soil from covering the copper wire 11 and affecting the conductivity.

[0024] The lower tube 1 is provided with a limit platform 12 located below the copper brush 8 and matched with the lower end of the upper tube 2. After the upper tube 2 is inserted into the lower tube 1, the upper tube 2 contacts the limit platform 12. The limit platform 12 prevents the upper tube 2 from continuing to descend, so that the copper brush 8 can extend into the groove with the copper wire 11 on the upper tube 2 and contact the copper wire 11. The upper tube 2 is provided with an inverted skirt-shaped support plate 5, which forms a lifting and resetting mechanism for the petal-shaped spring piece 41. After the data collection is completed, the upper tube 2 is pulled upward. During the pulling process, the support plate 5 lifts the drooping petal-shaped spring piece 41 upward to ensure that the petal-shaped spring piece 41 can be reset after the upper tube 2 is pulled out.

[0025] The upper end of the lower tube 1 is also provided with a conical introduction port 6 located above the sealing cap 4; the upper end range of the conical introduction port 6 is larger than the inner diameter of the lower tube 1, so that the upper tube 2 can be smoothly inserted into the lower tube 1 under the guidance of the conical introduction port 6.

[0026] Furthermore, the upper tube 2 can also be configured as a split structure, comprising a cylinder 21 with openings at both the upper and lower ends and a combination 22 connected to the cylinder 21, the support plate 5 being disposed on the cylinder 21, the upper end of the combination 22 being detachably connected to the cylinder 21, the lower end extending along the cylinder 21 and forming a tapered end in conjunction with the cylinder 21, the upper end of the combination 22 being provided with an internal threaded sleeve 23, the upper end of the cylinder 21 being provided with an external thread, the combination 22 being able to be separated and connected to the cylinder 21 by means of the screwing of the internal threaded sleeve 23 and the external thread, resulting in a simple structure and easy assembly and disassembly. The limiting platform 12 is provided with a tapered through-hole for the combination 22 to pass through.

[0027] Before data collection, the assembly 22 is inserted into the cylinder 21 from top to bottom, and the assembly 22 is rotated so that the internal threaded sleeve 23 is screwed together with the external thread on the cylinder 21 to form the upper tube 2. The lower end of the upper tube 2 of the assembly 22 is matched with the lower end of the cylinder 21 to form a closed cone of the upper tube 2; when it is necessary to clean the soil in the lower tube 1, after the upper tube 2 is inserted into the lower tube 1, the internal threaded sleeve 23 is rotated, and the internal threaded sleeve 23 and the assembly 22 are removed from the cylinder 21. A cavity is formed in the cylinder 21, and the cavity of the cylinder 21 can be used to extend into the lower tube 1 to clean the soil in the lower tube 1.
