Description

Technical Field

[0001] The invention relates to the technical field of soil monitoring, and in particular to an adjustable soil monitoring device. Background Art

[0002] Soil monitoring refers to understanding the physical, chemical and biological properties of soil through a series of scientific experiments and measurements in order to assess the health, fertility, pollution status, etc. of the soil. This process includes sampling, pretreatment, analysis and measurement, and result evaluation.

[0003] After searching, the Chinese patent with publication number CN117214416A discloses a soil monitoring device and its use method, which includes the following elements and structures: a collection terminal, which is arranged in the soil; a column, which is arranged on the side of the collection terminal, and a control box is arranged on the column, and a controller connected to the collection terminal is arranged in the control box; an electric lifting hollow pressure rod is arranged on the column, and the outer end of the hollow pressure rod is electrically connected to the collection terminal, and the collection terminal is fixed to the surface of the soil. The probe sensor used in the present invention is low-cost and replaceable, and the collection terminal adopts a multi-directional detection structure with layered points. The detection structure is novel and ingenious in design, and can realize the electric extension and disassembly of the probe sensor and the positioning pin, which is convenient for the maintenance and fixation of the collection terminal; the device adopts unattended solar power supply, the wires are not exposed, and the collection terminal has the functions of anti-theft and self-fixation, long service life, can avoid damage, and stable and reliable operation. However, the above scheme still has the following shortcomings when it is actually used:

[0004] 1. When installing the sensor, the tubular part is first inserted into the soil, and the sensor is pushed into the detection position. When the tubular part penetrates the soil, the soil particles around it will be squeezed and displaced, causing the soil compactness in the area to change, or even local relaxation. If the sensor is then inserted into the soil that may have been relaxed or changed in nature, it is likely that data with large deviations will be collected, which cannot accurately reflect the true condition of the soil. This will not only reduce the reliability of the monitoring results, but may also mislead subsequent soil management decisions;

[0005] 2. When soil monitoring is required, the staff first needs to place the sensor accurately at the predetermined location. In addition, in order to obtain soil samples in the area for laboratory analysis, they need to carry and operate a separate sampling device again, repeating the tedious steps of excavation, sampling, and packaging. This repetitive work not only increases the burden on the staff, but also prolongs the monitoring cycle and reduces overall work efficiency.

[0006] Therefore, the present application provides an adjustable soil monitoring device to meet the needs of accurate soil monitoring and sampling. Summary of the invention

[0067] 2. This adjustable soil monitoring device, by setting up a sampling component, can drive the adjustment frame to slide in the sampling port through the cooperation of the sampling spoon and the fixed rod, thereby realizing precise adjustment of the sampling position, making the sampling process more flexible, and being able to adjust the sampling depth or angle as needed, thereby improving the accuracy and efficiency of sampling.

During the sliding of the adjustment frame 61, the baffle 62 can slide in the give way groove to block the position of the sampling port 5 outside the adjustment frame 61 to prevent a large amount of soil from entering the ground-inserting tube. Inside the tube 4, since the ground-inserting tube 4 is inserted into the soil for use, the soil outside can squeeze the baffle 62, so that a certain friction force is generated between the baffle 62 and the give way groove.

[0094] Under the drive of the synchronous belt 88, the driven wheel 83 at the end of the oil cylinder 89 can rotate synchronously and drive the driving screw 810 to rotate. Since the piston plate 91 slides in the oil cylinder 89 through the slide groove and the slider, and the thread is mounted on the driving screw 810, the driving screw 810 can drive the piston plate 91 to slide when it rotates.

Moreover, as the push rod 94 moves, the monitoring probe 95 at the end of the push rod 94 can be inserted into the soil to realize the monitoring of various soil data. Moreover, the monitoring probe 95 can be inserted into the soil far away from the ground-inserting tube 4, thereby ensuring the accuracy of the monitoring data.
