Description

Technical Field

[0001] The utility model relates to the technical field of test devices, in particular to a test device for screening soil acid conditioners. Background Art

[0002] Soil acid conditioners are substances that can adjust the pH value of soil and reduce the acidity in the soil. They are usually composed of natural minerals, alkaline substances or organic materials. They can neutralize the acidic substances in the soil, improve the chemical properties of the soil, and create a more suitable soil environment for plant growth. The properties of soil in different regions vary greatly, and the pH value, texture, and nutrient content of the soil are different. Therefore, it is necessary to screen out acid conditioners suitable for different soil types to achieve the best conditioning effect. In the prior art, there is a soil acid conditioner screening test device with constant moisture content. Its technical solution includes several groups of test components. The test components include a weight sensor, a tray, a soil basin containing a soil sample, a pH sensor for detecting the soil inserted in the soil sample, and a non-contact suspended cover above the soil basin. This device manages the moisture content in the soil sample through weight control.

[0003] In the above working process, the pH sensor is fixed in position during the detection process, which makes the detection data accidental and leads to large errors in the experimental data. Therefore, we propose a test device for screening soil acid conditioners. Summary of the Invention

A weight sensor 2 is provided at the bottom of the soil basin 3, and a shield 4 is hingedly connected to the top of the soil basin 3. A pH sensor 5 is inserted into the shield 4. The pH sensor 5 is used to detect the acidity of the soil sample.

[0031] Among them, a bracket 7 is fixedly installed on one side of the base 1, and one side of the shield 4 is hinged to the bracket 7 through an axis. A support plate 8 is provided on the top of the weight sensor 2, and the soil basin 3 is placed on the top of the support plate 8. The bracket 7 is an iron bracket. A magnetic part 6 is fixedly installed on the side of the shield 4 close to the bracket 7. The shield 4 is rotated so that the magnetic part 6 is close to the bracket 7, and the shield 4 is fixed to one side of the soil basin 3 through the magnetic effect between the magnetic part 6 and the iron bracket 7, so that the shield 4 is fully opened, which is convenient for the staff to operate;

[0032] In this embodiment, the adjustment component includes a rotating shaft 13 rotatably mounted in the mask 4, and the adjustment component also includes a motor 9 fixedly mounted on the top of the mask 4 for driving the rotating shaft 13 to rotate. When the motor 9 is started, the rotating shaft 13 rotates, thereby driving the pH sensor 5 provided at the telescopic end of the electric push rod 14 to rotate in the soil basin 3. The electric push rod 14 is fixedly mounted on the rotating shaft 13, and a sliding seat 16 is fixedly mounted on the telescopic end of the electric push rod 14. The pH sensor 5 is slidably mounted in the sliding seat 16. The electric push rod 14 is started to adjust the rotation radius of the pH sensor 5.

[0033] Among them, an L-shaped slide plate 161 is slidably installed in the sliding seat 16, and a screw rod 162 is rotatably installed in the sliding seat 16. The L-shaped slide plate 161 and the screw rod 162 are threadedly connected. A motor 163 for driving the screw rod 162 is fixedly installed on the top of the sliding seat 16. A placement seat 17 is fixedly installed on the side of the L-shaped slide plate 161 away from the rotating shaft 13. A placement hole is opened at the bottom of the placement seat 17. The pH sensor 5 is movably arranged in the placement hole. A limiting member 51 is fixedly installed on the pH sensor 5. When the motor 163 is started, the screw rod 162 rotates, thereby causing the L-shaped slide plate 161 to move up and down in the sliding seat 16, thereby driving the placement seat 17 where the pH sensor 5 is placed to move up and down, thereby realizing the adjustment of the depth of the pH sensor 5 inserted into the soil sample, thereby realizing the multi-dimensional position adjustment of the pH sensor 5 in three-dimensional space, so that the pH sensor 5 can detect the soil at different positions and depths, reducing the randomness caused by fixed position detection, thereby reducing the error of the detection data and fully reflecting the acidity of the soil;

[0034] In addition, a water inlet pipe 11 and an air outlet pipe 10 are fixedly installed on the top of the mask 4.

A shower head 12 is fixedly connected to the side of the connector 15 away from the electric push rod 14. The shower head 12 is connected to the connector 15. After water flows into the water inlet pipe 11, it is sprayed on the soil sample in the soil basin 3 through the shower head 12. Starting the motor 9 rotates the rotating shaft 13, thereby causing the shower head 12 to rotate as well, thereby achieving uniform spraying of the soil sample, ensuring the uniformity of the soil moisture content, avoiding the influence of local moisture differences on soil acidity, thereby improving the stability of the soil conditions during the test, and further improving the accuracy of the test results.

[0035] The working principle of this embodiment is as follows: during operation, the water inlet pipe 11 is connected to the external water source equipment, and after water flows into the water inlet pipe 11, the water is sprayed on the soil sample in the soil basin 3 through the sprinkler 12, and the motor 9 is started to rotate the rotating shaft 13, so that the sprinkler 12 fixedly connected to the rotating shaft 13 through the connecting piece 15 is also rotated, thereby achieving uniform spraying of the soil sample, ensuring the uniformity of the soil moisture content, avoiding the influence of local moisture differences on the soil acidity, thereby improving the stability of the soil conditions during the test, and further improving the accuracy of the test results; when it is necessary to detect the acidity of the soil sample through the pH sensor 5, the motor 9 is started to rotate the rotating shaft 13, thereby driving the pH sensor 5 provided at the telescopic end of the electric push rod 14 to move in the soil. The basin 3 rotates, the electric push rod 14 is started to adjust the rotation radius of the pH sensor 5. In addition, the motor 163 is started to rotate the screw rod 162, so that the L-shaped slide 161 threadedly connected to the screw rod 162 moves up and down in the sliding seat 16, thereby driving the placement seat 17 fixedly connected to one side of the L-shaped slide 161 on which the pH sensor 5 is placed to move up and down, thereby adjusting the depth of the pH sensor 5 inserted into the soil sample, thereby realizing multi-dimensional position adjustment of the pH sensor 5 in three-dimensional space, so that the pH sensor 5 can detect the soil at different positions and depths, reducing the randomness caused by fixed position detection, thereby reducing the error of the detection data and fully reflecting the acidity of the soil.
