Description

Technical Field

[0001] This utility model relates to the field of soil monitoring technology, and in particular to a soil fertility monitoring device. Background Technology

[0002] Orchards are one of the important agricultural industries in my country. The growth of fruit trees and the quality of fruit are closely related to soil fertility. Soil fertility refers to the soil's ability to provide various nutrients and water needed for crop growth. It is a comprehensive indicator reflecting the degree of soil fertility and an important factor affecting orchard yield and quality. Therefore, monitoring soil fertility can help us understand the soil fertility status in a timely manner and facilitate the implementation of fertilizer application control measures. However, current soil fertility monitoring equipment can usually only monitor soil at a single depth, resulting in low overall accuracy.

[0003] For example, a simplified orchard soil fertility monitoring device disclosed in Chinese patent literature (Publication No.: CN221007578U) integrates all necessary functions into one unit, reducing the device's size and optimizing its operation, making it more convenient to use. When it is necessary to move the probe assembly or change the monitoring plot, the user can easily store the probe assembly in a rectangular storage slot, thereby reducing the device's size and making it more convenient to carry. This also effectively reduces the risk of damage to the probe assembly from external risks or collisions during movement. Thus, the device achieves a balance of simplicity, practicality, portability, and integration.

[0004] However, its probe assembly can only monitor soil at a single depth. The fertility distribution of orchard soil varies at different depths, and crop roots absorb nutrients differently at different growth stages. Monitoring only a single depth cannot comprehensively reflect soil fertility status, making it difficult to accurately assess the soil's overall capacity to provide nutrients and water to fruit trees, thus reducing the accuracy of monitoring results. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that soil fertility monitoring at a single depth can easily affect the accuracy of monitoring results.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soil fertility monitoring device includes a monitoring sleeve, wherein the monitoring sleeve is provided with a multi-layer monitoring mechanism inside;

[0008] The multi-layer monitoring mechanism includes rectangular slide bars. One end of a plurality of rectangular slide bars is arranged in a linear array and fixedly connected to the inner wall of the monitoring sleeve. A movable block is slidably sleeved on the outside of the rectangular slide bars. A probe body is fixedly installed on one side of the movable block. A return spring is fixedly connected to one side of the movable block. One end of the return spring is fixedly connected to the inner wall of the monitoring sleeve.

[0009] The monitoring sleeve is equipped with a drive mechanism inside, which drives the multi-layer monitoring mechanism to perform synchronous moving and extending movements.

[0010] Preferably, the monitoring sleeve has through holes arranged in a linear array on its outer surface, and a rubber sleeve is fixedly fitted onto the inner wall of the through holes.

[0011] Preferably, a control housing is fixedly installed at the upper end of the monitoring sleeve, and a waterproof display screen is fixedly installed above the control housing.

[0012] Preferably, the driving mechanism includes a lead screw, the lower end of which is rotatably connected to the inner bottom wall of the monitoring sleeve via a bearing, and the upper end of which passes through the monitoring sleeve and is fixedly connected to a rotating handle.

[0013] Preferably, the lead screw is externally threaded with threaded blocks arranged in a linear array, and a first support is fixedly connected to one side of the threaded blocks. A support rod is hinged to the inner wall of the first support via a pin.

[0014] Preferably, one end of the support rod is hinged to a second support via a pin, and one side of the second support is fixedly connected to the other side of the movable block.

[0015] Preferably, a pointed cone-shaped insert is fixedly connected to the lower end of the monitoring sleeve, and symmetrically distributed blocks are fixedly connected to the outside of the monitoring sleeve, with a gripping handle fixedly connected to the upper end of each block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, a multi-layer monitoring mechanism can monitor soil fertility at different depths. Compared with single-depth monitoring, it can more comprehensively and accurately reflect the soil fertility status and improve the accuracy of comprehensive soil fertility assessment. The drive mechanism is driven by a screw, which is simple and reliable in structure and can realize the synchronous extension and retraction of the multi-layer monitoring mechanism. The handle makes it easy for operators to apply force to insert or pull out the monitoring sleeve. The waterproof display screen can display soil nutrient content data in real time for easy on-site viewing. The wireless communication module can transmit data to the cloud or designated devices, facilitating remote monitoring and management. Attached Figure Description

[0027] Example

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a soil fertility monitoring device, including a monitoring sleeve 1, a multi-layer monitoring mechanism, a drive mechanism, and related auxiliary components. The monitoring sleeve 1 serves as the main support structure, accommodating the multi-layer monitoring mechanism and the drive mechanism, and providing them with a stable working environment. The multi-layer monitoring mechanism is responsible for detecting soil fertility at different depths. The drive mechanism is used to control the synchronous extension and retraction of the multi-layer monitoring mechanism. The auxiliary components include related components that facilitate operation and data processing and display.

[0029] Multiple rectangular slide rods 2 are arranged in a linear array at one end and are fixedly connected to the inner wall of the monitoring sleeve 1 by welding or other means. The outer side of the rectangular slide rods 2 is slidably sleeved with the moving block 21 to provide guidance for the movement of the moving block 21.

[0030] A probe body 22 is installed on one side of the movable block 21 by means of screws or other means, which is used to detect soil fertility. The probe body 22 is connected to a sensor inside the control housing 25 through a spiral wire with elasticity (existing technology, not shown in the figure). The electrical signal is transmitted to the controller. The data processing module in the controller processes the electrical signal and analyzes the nutrient content in the soil through a specific algorithm. A reset spring 23 is fixedly connected to the other side of the movable block 21 by means of welding or other means. The other end of the reset spring 23 is fixedly connected to the inner wall of the monitoring sleeve 1, which can assist the movable block 21 in resetting.

[0031] The lower end of the lead screw 3 is rotatably connected to the inner bottom wall of the monitoring sleeve 1 through a high-precision bearing, ensuring that the lead screw 3 can rotate flexibly. The upper end of the lead screw 3 passes through the monitoring sleeve 1 and is fixedly connected to a rotating handle 31 by welding or other means, which is convenient for operators to manually drive.

[0032] The lead screw 3 is threadedly connected to the outside of the threaded blocks 32 arranged in a linear array. A first support 33 is fixedly connected to one side of the threaded blocks 32 by welding or other means. The inner wall of the first support 33 is hinged to the support rod 34 by a pin. The other end of the support rod 34 is hinged to the second support 35 by a pin. One side of the second support 35 is fixedly connected to the other side of the moving block 21 by welding or other means, so as to realize the transmission control of the multi-layer monitoring mechanism by the drive mechanism.

[0033] The monitoring sleeve 1 has through holes arranged in a linear array on its exterior. A rubber sleeve 24 is fixedly fitted onto the inner wall of the through holes by means of interference fit or other means, which can seal the gap between the probe body 22 and the monitoring sleeve 1 to prevent soil from entering the contaminated interior.

[0034] The upper end of the monitoring sleeve 1 is fixed with screws or other means to install a control housing 25. The control housing 25 integrates sensors, controllers, power modules, data processing modules, and wireless communication modules. A waterproof display screen 26 is installed on the top of the control housing 25 by screws or other means. The processed data is displayed in real time on the waterproof display screen 26 for easy viewing by on-site operators. At the same time, the data is transmitted to the cloud or user-specified devices through the wireless communication module for remote monitoring and management. Throughout the process, the power module typically uses rechargeable batteries or other sustainable energy sources to provide the necessary power to the equipment.

[0035] The lower end of the monitoring sleeve 1 is fixedly connected to a pointed cone-shaped insert 4 by welding or other means, which facilitates insertion into the soil. The outside of the monitoring sleeve 1 is fixedly connected to symmetrically distributed stop blocks 5 by welding or other means. The upper end of the stop block 5 is fixedly connected to a grip handle 6 by welding or other means, which facilitates the operator to apply force to insert or pull out the monitoring sleeve 1. At the same time, the stop block 5 can control the insertion depth.

[0036] The working process of this utility model:

[0037] Step 1: The operator holds the handle 6 and uses the pointed cone block 4 to insert the monitoring sleeve 1 into the soil. During this process, the stop block 5 plays a role in depth control to prevent the monitoring sleeve 1 from being inserted too deeply and causing damage to the device. After inserting to the appropriate depth, the operator turns the rotating handle 31, which drives the lead screw 3 to rotate. Since the lead screw 3 and the threaded block 32 adopt a threaded connection structure, the threaded block 32 will move down along the lead screw 3. The threaded block 32 drives the moving block 21 to slide on the rectangular slide bar 2 through the linkage mechanism composed of the first support 33, the support rod 34, and the second support 35, so that the probe body 22 extends out of the monitoring sleeve 1 and is inserted into the soil at different depths.

[0038] Step two: After the probe body 22 is inserted into the soil, it reacts with the nutrients in the soil and generates an electrical signal. The electrical signal is transmitted to the controller. The data processing module in the controller processes the electrical signal and analyzes the nutrient content in the soil through a specific algorithm. The processed data is displayed in real time on the waterproof display screen 26 for easy viewing by on-site operators. At the same time, the data is transmitted to the cloud or a user-specified device through the wireless communication module for remote monitoring and management. Throughout the process, the power module provides the necessary power to the device.

[0039] Step 3: After monitoring is completed, the operator rotates the handle 31 in the opposite direction to make the threaded block 32 move upward and drive the probe body 22 to retract. During this process, the reset spring 23 exerts its elastic force to assist the moving block 21 in resetting and avoid jamming.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
