[0002] In saline-alkali land, soil moisture monitoring is crucial for salt regulation and crop growth; water evaporation will aggravate surface salt accumulation, while reasonable irrigation can reduce salt concentration in the root zone through leaching; accurate monitoring can optimize irrigation plans, avoid water waste and secondary salinization, and provide a scientific basis for saline-alkali land improvement.

[0003] The soil moisture monitoring devices currently used still have the following problems:

[0004] 1. When the device is transported, it cannot provide good support for the soil moisture sensor, causing the soil moisture sensor to be easily bumped;

[0005] 2. It is inconvenient for staff to judge the installation position of the soil moisture sensor. When the soil moisture sensor is installed in a raised or depressed place, it will affect the subsequent moisture monitoring accuracy;

[0006] 3. Gaps are easily generated between the soil moisture sensor and the soil, which makes it inconvenient for workers to press the soil outside the soil moisture sensor and also affects the subsequent moisture monitoring accuracy. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The arrangement of the two support springs a in the present invention supports the soil moisture sensor, ensuring a certain distance between the bottom of the soil moisture sensor and the bottom of the support ring frame, thereby preventing the soil moisture sensor from being bumped during transportation. This also makes it easier for workers to disassemble or install the soil moisture sensor and replace it.

[0020] In addition, when the soil moisture sensor needs to be connected to the soil, the staff presses down the moisture monitoring frame; when the bottom of the moisture monitoring frame is flush with the bottom of the support ring frame, the two limit pins are concentric with the two limit slots; when the two limit pins are concentric with the two limit slots, the two limit pins can be automatically inserted into the two limit slots under the action of the two support springs b, which plays a positioning role for the soil moisture sensor after moving.

[0021] 2. The provision of the gripping handle of the present invention facilitates the rotation of the arc-shaped auxiliary frame by the operator; the provision of the two arc-shaped limiting holes and the circular limiting rod limits the rotation angle of the arc-shaped auxiliary frame, so that the arc-shaped auxiliary frame can rotate a maximum of 180 degrees;

[0022] In addition, after the arc-shaped auxiliary frame rotates one hundred and eighty degrees, when the staff continues to move the gripping handle, the arc-shaped movable block can slide in the circular track, so that the arc-shaped auxiliary frame moves simultaneously with the arc-shaped movable block; when the arc-shaped auxiliary frame is stuck by the soil during movement, the soil at the support ring frame is in a sunken position, which is prone to water accumulation on rainy days and easily affects the subsequent moisture monitoring accuracy; when the arc-shaped auxiliary frame is not stuck by the soil during movement, the staff observes the scratches between the conical feedback block and the soil. When the scratches between the conical feedback block and the soil are basically a full circle, it means that the soil at the support ring frame is relatively flat; when the scratches between the conical feedback block and the soil are severely incomplete, it means that the soil at the support ring frame is in a raised position, which will also affect the subsequent moisture monitoring accuracy, making it easier for the staff to install the support ring frame in the correct position.

[0023] 3. The setting of a circle of circular positioning rods in the present invention plays a positioning role for the support ring frame, so that the support ring frame can be in a stable state after installation; when the staff rotates the two adjusting screws, the extrusion and fitting frame will move downward;

[0024] In addition, when the extrusion and fitting frame moves downward, the four conical hollow covers can be inserted into the soil, causing the soil outside the four conical hollow covers to move; when the four conical hollow covers move downward, the soil will only move in a circle of arc-shaped blocking plates, which is conducive to close contact between the soil and the soil moisture sensor.
