Description

Technical Field

[0001] This utility model relates to a soil nutrient analyzer, belonging to the field of soil nutrient analysis technology. Background Technology

[0002] Soil nutrients are the essential nutrients that the soil provides for plant growth, and they are an important indicator of soil fertility.

[0003] Traditional outdoor soil nutrient analysis instruments usually require manual collection of soil samples before measurement. The sampling and measurement processes are not continuous, and the whole process is time-consuming, resulting in low efficiency of soil nutrient analysis and the inability to obtain results in real time.

[0004] In addition, traditional soil nutrient analysis instruments require manual cleaning of the sample after each measurement before the next measurement can be performed, which is inefficient and the cleaning is not thorough, making continuous measurement difficult.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a soil nutrient analyzer that can solve the problems of low efficiency in soil nutrient analysis, inability to obtain results in real time, and difficulty in continuous measurement.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: The soil nutrient analyzer includes a sampling tube arranged vertically. The sampling tube has a hollow structure and a sampling port at the bottom. A sampling shaft for longitudinally transporting soil is inserted inside the sampling tube. The bottom end of the sampling shaft extends out of the sampling port. Screw blades are fixed to the main body of the sampling shaft. A handle and a battery casing are arranged in sequence on the left side of the sampling tube. A guide tube and a detection chamber are arranged in sequence on the right side of the sampling tube. The detection chamber is connected to the inner cavity of the sampling tube through the guide tube.

[0008] Furthermore, the top of the sampling tube is provided with an enlarged end, and a motor is fixedly installed inside the enlarged end. The output shaft of the motor is connected to the top of the sampling shaft through a coupling.

[0009] Furthermore, the top of the enlarged end is provided with heat dissipation holes.

[0010] Furthermore, a support ring is fixedly installed inside the sampling tube. The support ring is sleeved on the sampling shaft and rotates to support it. The support ring is located above the auger blades.

[0011] Furthermore, both the grip and the guide tube are inclined.

[0012] Furthermore, a storage battery is installed inside the battery casing, which provides power to the motor and the probe.

[0013] Furthermore, a downward-facing probe is installed above the testing chamber.

[0014] Furthermore, the bottom of the testing chamber is equipped with a flip-up cover.

[0015] Furthermore, a hanging ear is provided on one side of the top of the enlarged end.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This invention integrates sampling, conveying, and detection functions. It uses a motor-driven auger blade to automatically collect and convey soil, and employs an optical probe to directly and rapidly detect the soil in the detection chamber. Nutrient content results can be obtained within minutes, enabling real-time on-site analysis and greatly improving efficiency.

[0017] The bottom of the testing chamber is equipped with a flip-up cover, which can be quickly opened after testing to automatically discharge the soil using gravity. This efficient cleaning method facilitates multiple continuous measurements and is suitable for large-area soil surveys.

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2As shown in the figure, this utility model provides a soil nutrient analyzer, including a sampling tube 1 arranged vertically. The sampling tube 1 has a hollow structure and a sampling port 2 at the bottom end. A sampling shaft 5 for longitudinally transporting soil is installed inside the sampling tube 1. The bottom end of the sampling shaft 5 extends out from the sampling port 2. A screw conveyor blade is fixedly connected to the main body of the sampling shaft 5. A handle 8 and a battery shell 9 are arranged sequentially on the left side of the sampling tube 1. A guide tube 11 and a detection chamber 12 are arranged sequentially on the right side of the sampling tube 1. The detection chamber 12 is connected to the inner cavity of the sampling tube 1 through the guide tube 11.

[0023] The top of the sampling tube 1 is provided with an enlarged end 3, and a motor 6 is fixedly installed inside the enlarged end 3. The output shaft of the motor 6 is connected to the top of the sampling shaft 5 through a coupling. The motor 6 drives the sampling shaft 5 and the auger blades to collect soil.

[0024] The top of the enlarged end 3 is provided with a heat dissipation hole 4, which is beneficial for the heat dissipation of the motor 6.

[0025] A support ring 7 is fixedly installed inside the sampling tube 1. The support ring 7 is sleeved on the sampling shaft 5 and rotates to support it. The support ring 7 is located above the auger blades and can also play a role in obstructing the flow, allowing the soil lifted here to enter the guide tube 11.

[0026] Both the handle 8 and the guide tube 11 are inclined. The inclined handle 8 facilitates downward pressure on the sampling tube 1, allowing for the collection of soil samples from different depths. The inclined guide tube 11 facilitates soil flow, transporting the soil into the testing chamber 12.

[0027] The battery casing 9 houses a storage battery 10, which provides power to the motor 6 and the probe 14.

[0028] Above the detection chamber 12, a downward-facing probe 14 is installed. The probe 14 is made using the principle of optical measurement. When a soil sample is irradiated with a broadband light, the chemical bonds in the organic matter and minerals in the soil will absorb light of a specific wavelength. The detector receives the reflected light and forms a spectral curve, thereby quickly predicting its nutrient content.

[0029] The bottom of the testing chamber 12 is equipped with a flip-down cover 13. After the cover 13 is flipped down, the soil inside the testing chamber 12 can be cleaned efficiently.

[0030] A hanging ear 15 is provided on one side of the top of the enlarged end 3. A hanging rope can be threaded through the hanging ear 15 to facilitate the carrying and transfer of the entire device.

[0031] The specific working process of this utility model Sampling and transport: The operator holds the tilted handle and places the instrument vertically at the point to be measured, so that the sampling port at the bottom contacts the soil surface; the operator applies downward pressure, and the motor drives the sampling shaft and the auger blades on it to rotate at high speed, continuously pushing the soil at the bottom upward in a spiral.

[0032] Soil diversion: The soil lifted by the auger blades reaches the support ring. The support ring blocks the soil from moving upwards, forcing the soil to change direction and enter the diversion pipe on the side. Since the diversion pipe is set at an angle, the soil slides into the testing chamber under its own gravity.

[0033] Rapid detection: Once the testing chamber is filled with soil, the probe located above it begins operation. A broad-spectrum beam of light covering multiple wavelengths is emitted towards the soil sample. The chemical bonds contained in various organic substances and minerals in the soil selectively absorb light at specific wavelengths. The detector inside the probe accurately measures and receives the light signals reflected back from the soil surface, thereby quickly predicting the content of various nutrients in the soil.

[0034] Sample cleaning and preparation for the next measurement: After the test is completed, open the bottom cover of the testing chamber and flip it downwards. The tested soil inside the chamber will automatically drain out under gravity.

[0035] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
