Description

Technical Field

[0001] This utility model relates to the field of soil testing equipment technology, and in particular to an efficient soil pH testing and optimization device. Background Technology

[0002] Soil pH reflects the acidity or alkalinity of the soil, directly affecting nutrient availability, microbial activity, and plant growth. However, existing soil pH testing devices fail to adequately control factors such as CO2, dust, and oxygen, which can influence the test results.

[0003] 1. The significant impact of CO2 on soil pH: Studies have shown a negative correlation between soil pH and CO2 partial pressure, especially in calcareous soils. When CO2 pressure decreases from 0.77 atm to 0.0003 atm, the pH can increase from 6.4 to 9.21. This is because the dynamic balance between the carbonate system and hydrogen ion activity in the soil is disrupted, causing the measured results to deviate from the true values. Therefore, isolating external CO2 is crucial for improving experimental accuracy.

[0004] 2. The Influence of Oxygen: Although oxygen has a relatively small direct impact on pH, dissolved oxygen can indirectly alter the soil environment in certain soil microbial activities or redox reactions (such as organic matter decomposition, nitrification / denitrification). If long-term stable monitoring is required for the experiment, a constant oxygen environment can reduce such interference.

[0005] 3. The harmful effects of dust on the human body: Ordinary dust (>10µm) can be expelled through nasal mucus and cilia, but fine particulate matter such as PM2.5 can directly reach the alveoli, causing acute symptoms such as inflammation and asthma. High dust concentrations are generated during soil mixing, necessitating physical isolation to reduce the risk of inhalation for operators.

[0006] In addition to the problems mentioned above, existing detection devices have low experimental efficiency, and generally use a single electrode device for measurement. The later the sample, the greater the influence of the environment. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an efficient soil pH detection and optimization device in order to overcome the shortcomings of the existing technology.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a high-efficiency soil pH detection and optimization device, including a detection host, a bottom support plate is provided on one side of the detection host, and a sample tray is placed on the bottom support plate; a detection crossbeam is slidably connected to the upper end of the detection host in the front-back direction through the cooperation of an overhead guide rod and a sliding connecting column.

[0009] The detection beam is connected to the left and right ends by a sliding groove and an electrode mounting plate is slidably connected in the vertical direction. The electrode mounting plate is provided with a group of mounting holes at equal intervals in the horizontal direction and a number of electrode synchronous measurement modules are provided on the electrode mounting plate.

[0010] By adopting the above technical solution, multiple electrode synchronous measurement modules are integrated, and the extended robotic arm is evenly distributed to achieve parallel measurement of pH values ​​at different points on the soil sample, which significantly shortens the experimental time (especially suitable for large sample size or soil heterogeneity studies), while avoiding gas environment fluctuations and operational errors caused by multiple measurements with a traditional single electrode.

[0011] The base plate is provided with a sealed dust cover that houses the detection host and the detection beam, and the top of the sealed dust cover is provided with an air filter.

[0012] By adopting the above technical solution, the sealed dustproof glass cover allows for visualization of the sample status, effectively isolates external air, and avoids CO2 / O2 interference; the built-in high-efficiency air filter (HEPA) adsorbs dust and prevents it from escaping.

[0013] The detection host is also equipped with a gas replacement component, which includes a gas cylinder, a gas pump, a gas outlet, and a sensor group. The gas cylinder and gas pump are located on the side bottom plate on the back of the detection host outside the sealed dust cover, and the gas outlet is installed on the front panel of the detection host inside the sealed dust cover. The gas cylinder, gas pump, and gas outlet are connected by pipes.

[0014] Furthermore, the electrode synchronous measurement module of this utility model includes a robotic arm mounted on the electrode mounting plate, and an electrode is mounted on the lower end of the robotic arm.

[0015] Furthermore, the sample tray of this invention has a plurality of sample placement slots arranged in a matrix, wherein the spacing of a single row of sample placement slots matches the spacing of the electrode synchronous measurement module.

[0016] Furthermore, the sensor group of this utility model includes a gas sensor and a temperature and humidity sensor installed on the upper and lower sides of the gas outlet;

[0017] By adopting the above technical solution, the built-in gas sensor monitors the CO2 and O2 concentrations inside the enclosure in real time. The gas pump and gas replacement components (such as injecting inert gas or premixed gas) maintain a constant CO2 partial pressure (simulating the original soil environment). The integrated temperature and humidity sensor can be used with an automatic calibration module combined with AI algorithms (such as machine learning models) to optimize control parameters when necessary. It can adapt to different soil types. Data can be synchronized through the cloud platform, supporting remote monitoring and historical data review.

[0018] The beneficial effects of this utility model are:

[0019] 1. The high-efficiency soil pH detection optimization device of this utility model improves the accuracy, stability and safety of detection by adding a sealed dust cover to isolate and protect against CO2 / O2 interference, and by incorporating a high-efficiency air filter to optimize the experimental environment.
