Description

Technical Field

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

[0002] Soil testing is a technique that assesses the physical properties of soil, such as moisture, air, and heat, without causing chemical changes. It is closely related to farmland irrigation, drainage projects, and soil management, and is a fundamental task for agricultural planning and soil improvement.

[0003] However, most existing soil testing equipment lacks its own sampling function and requires the use of sampling equipment to perform soil testing. Sampling and testing of deep soil is often difficult due to structural limitations. When sampling the target soil, the soil sample is easily covered by the upper soil layer, affecting the overall sampling and testing effect. Furthermore, the stability of the equipment is difficult to guarantee during sampling of deep soil, and it is prone to shaking during the downward sampling process. Overall, the functionality is limited and the applicability is narrow. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a deep soil testing device to solve the above-mentioned deficiencies.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model discloses a deep soil testing device, comprising a stable bearing sleeve. A positioning bearing bracket is symmetrically and evenly fixedly installed around the lower outer perimeter of the stable bearing sleeve. A motor bearing support plate is fixedly installed on one side of the lower outer perimeter of the stable bearing sleeve, and a soil testing analyzer is fixedly installed on the other side. Limiting stroke brackets are symmetrically fixedly installed on both sides of the upper end of the stable bearing sleeve. A rotating connecting groove is pre-set at the bottom of the stable bearing sleeve. A driven gear is movably installed at the bottom of the stable bearing sleeve. A rotating connecting clip is fixedly installed at the upper end of the driven gear. A sampling probe screw is movably installed inside the driven gear, and a sampling soil-breaking cone is pre-set at the bottom of the sampling probe screw.

[0007] As a preferred embodiment of the deep soil testing equipment of this utility model, the positioning support bracket has a positioning pile adapter hole pre-set on the side of the bottom. A sampling drive motor is fixedly installed on the upper end of the motor support plate. The output shaft of the sampling drive motor passes through the motor support plate and is fixedly connected to a transmission gear. The installation position of the transmission gear at the bottom of the motor support plate and the installation position of the driven gear at the bottom of the stable support sleeve are on the same horizontal line. The driven gear and the transmission gear are meshed with each other.

[0008] By adopting a meshing transmission structure, the overall structure of the equipment is more rationally arranged, which helps to carry out deep soil sampling and testing work more efficiently and quickly.

[0009] In a preferred embodiment of the deep soil testing equipment of this utility model, the driven gear has a pre-set threaded transmission groove inside, the thread specification inside the threaded transmission groove corresponds and matches the external thread specification of the sampling probe screw, the limit stroke bracket has a top limiting block movably installed inside, the bottom of the top limiting block is fixedly installed with a positioning rotary connecting seat, the top of the sampling probe screw is fixedly installed with an alignment assembly head, the external specification of the alignment assembly head corresponds and matches the internal specification of the positioning rotary connecting seat, and the sampling probe screw is rotatably connected to the positioning rotary connecting seat through the alignment assembly head;

[0010] As a preferred embodiment of the deep soil testing equipment of this utility model, a directional groove is longitudinally provided in the middle position of the inner side of the limiting stroke support, and sliding connecting blocks are symmetrically fixedly installed on both sides of the outer side of the capping limiting block. The external specifications of the sliding connecting blocks correspond and match with the internal specifications of the directional groove. The capping limiting block is slidably connected to the directional groove through the sliding connecting blocks.

[0011] By setting up a limit travel bracket, the overall stability of the sampling screw during the sampling process is effectively guaranteed, which helps to prevent the entire equipment from shaking due to hard soil texture during the sampling process, thus interfering with the use of the sampling work.

[0012] In a preferred embodiment of the deep soil testing equipment of this utility model, a rotating retaining ring is fixedly connected to the bottom of the sampling probe screw. A data acquisition device is sleeved on the outside of the rotating retaining ring. A rotating correlation inner groove is preset on the side of the data acquisition device. The inner specifications of the rotating correlation inner groove correspond and match with the outer specifications of the rotating retaining ring. The data acquisition device is rotatably connected to the rotating retaining ring through the rotating correlation inner groove. The data acquisition device has a built-in soil moisture sensor, temperature sensor, pH sensor, conductivity sensor, and data transmitter. A correlation spring wire is fixedly connected between the data acquisition device and the soil testing and analysis instrument. The data acquisition device and the soil testing and analysis instrument are electrically connected to each other through the correlation spring wire. At the same time, a soil analysis hopper is preset at the lower end of the soil testing and analysis instrument.

[0013] By combining a data acquisition unit with a soil testing and analysis instrument, the device can collect basic soil data at the appropriate depth in real time when the sampling probe screw reaches the appropriate depth. The rotating connection structure between the rotating inner groove and the rotating retaining ring can prevent the connecting spring wire from getting tangled with the sampling probe screw during the sampling process, thus avoiding affecting the overall normal operation and improving the overall safety and stability of the operation.

The outer diameter of the sampling collection cylinder corresponds to and matches the inner diameter of the telescopic assembly hole. A sampling inlet is opened on the side of the sampling collection cylinder. The sampling inlet is interconnected with the inside of the sampling collection cylinder. Telescopic guide grooves are symmetrically opened on both sides inside the telescopic assembly hole. Telescopic association sliders are symmetrically fixedly installed on both sides outside the sampling collection cylinder. The fixed installation position of the telescopic association slider outside the sampling collection cylinder corresponds to and matches the opening position of the telescopic guide groove inside the telescopic assembly hole. The external specifications of the telescopic association slider correspond to and match the internal specifications of the telescopic guide groove.

[0015] By employing a telescopic connection structure between the sampling cone and the sampling probe screw, the device can achieve the effect of collecting soil samples only at the target depth during the downward sampling process, thereby improving the overall accuracy of the sampling target.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] This utility model discloses a deep soil testing device. Through a threaded lifting structure and corresponding gear transmission, it achieves stable and continuous lifting operation while ensuring overall structural stability.

[0029] Specifically, by adopting a meshing transmission structure, the overall structural layout of the equipment is more rational, which helps to carry out deep soil sampling and testing more efficiently and quickly. The limit travel bracket 4 effectively ensures the overall stability of the sampling screw 12 during the sampling process, preventing the equipment from shaking due to hard soil texture, thus interfering with the sampling operation. The data acquisition unit 20 and the soil analysis instrument 5 enable the equipment to collect samples in real time when the sampling screw 12 reaches the appropriate depth. The device collects basic soil data at corresponding depths. The rotating connection structure between the rotating inner groove 23 and the rotating retaining ring 19 prevents the connecting spring wire 22 from getting tangled with the sampling screw 12 during the sampling process, thus affecting the overall normal operation. This effectively improves the overall safety and stability of the operation. The telescopic connection structure between the sampling cone 25 and the sampling screw 12 allows the device to collect soil data only at the target depth during the sampling process, improving the overall accuracy of the sampling target.

[0030] Working Principle: When using this equipment to test deep soil layers, the stabilizing support sleeve 1 should first be stably placed directly above the area to be sampled using the positioning support bracket 2. External adapter pins are then used to secure the equipment by passing through the positioning pin adapter holes 18. This ensures that the entire unit will not shake during sampling, preventing instability and affecting sampling results. This effectively improves the overall stability of the equipment during normal operation. The sampling drive motor 6 is then started, and its output shaft drives the transmission gear 9 to rotate synchronously. Between the transmission gear 9 and the driven gear 8... With the support of the meshing connection, the driven gear 8 is driven to rotate through the rotational connection between the rotating connecting clip 10 and the rotating connecting groove 7. The threaded connection between the threaded transmission groove 11 and the sampling probe screw 12 drives the sampling probe screw 12 to rotate, thereby causing the sampling cone 25 at the bottom of the sampling probe screw 12 to rotate synchronously and break the soil for deep soil sampling. During the downward movement, under pressure, combined with the telescopic sliding connection between the sampling association head 24 and the sampling collection cylinder 27, the sampling collection cylinder 27 is squeezed and contracted into the telescopic assembly hole 26 inside the sampling association head 24.This ensures that during the sampling process of the sampling cone 25, the upper soil layer will not enter the sampling collection cylinder 27 through the sampling inlet 28, thus preventing the overall sampling target from being affected by the mixing of the upper soil layer. When the sampling screw 12 rotates downwards, the data acquisition unit 20 will not rotate with the sampling screw 12 due to the adaptive rotational linkage structure between the inner groove 23 and the rotating retainer 19. This prevents the linkage spring wire 22 connecting the data acquisition unit 20 and the soil analyzer 5 from becoming entangled with the sampling screw 12, thus ensuring the overall sampling operation is not affected. When the sampling screw 12 drives the sampling cone 25 to a suitable depth, the data acquisition unit 20 uses its built-in soil moisture sensor, temperature sensor, pH sensor, and conductivity sensor to collect corresponding data from the surrounding deep soil. The collected data is then stably transmitted to the soil analyzer via the data transmitter under the electrical linkage of the linkage spring wire 22. When the sampling cone 25 reaches the target soil sampling depth, the motor-driven support plate 3 reverses its direction, causing the sampling screw 12 to lift the entire sampling cone 25. During this ascent, the sampling collection cylinder 27 extends from the telescopic assembly hole 26 via the sliding connection between the telescopic guide groove 29 and the telescopic linkage slider 30. Deep soil enters the sampling collection cylinder 27 through the sampling inlet 28. After the sampling cone 25 rises above the ground, the deep soil collected inside the sampling collection cylinder 27 can be removed and placed in the soil analysis hopper 21. The soil analysis instrument 5 then performs further data analysis. The system boasts a wide range of functionalities, a simple structure, and a rational component layout. It simultaneously achieves both deep sampling and data acquisition and detection, and its structural characteristics maximize overall stability, thus significantly improving overall performance, increasing work efficiency, and expanding its applicability.
