The technology is the main principle of the current soil moisture determination device, and can continuously, quickly and accurately measure the soil moisture. Meanwhile, the method can also be used for measuring the surface water content of the soil. The equipment response time of the general profile soil moisture measuring system is about 10-20 seconds, the system is suitable for mobile measurement and fixed-point monitoring, and the measurement result is slightly influenced by salinity.
However, when the profile soil moisture measuring system is used for measuring deeper soil moisture, the probe of the profile soil moisture measuring system may be damaged because the matched pre-punching device cannot ensure that the probe of the profile soil moisture measuring system is accurately inserted into the pre-punching hole at one time.
In addition, the existing soil moisture measurement needs to set a plurality of measuring points in the same area to measure the soil moisture data respectively. However, given the limited field operating conditions and the limited number of workers, and the influence of field temperature differences and moisture evaporation, the longer time interval between each measurement point affects the moisture measurement across the field, resulting in data distortion.
In addition, when the existing profile soil moisture measuring system is used, due to the diversity of components in soil, the solid gravel is very easy to damage a measuring probe in the downlink process, and the soil moisture measuring instrument is very expensive, so that the use cost is high.
See the following chinese patent documents:

The invention patent comprises a hole puncher and a soil moisture meter. The soil is punched by a puncher firstly, and then the soil moisture meter is used for measuring. However, there are technical drawbacks in that it is not possible to ensure that the measuring probe of the soil moisture meter is accurately inserted into the pre-drilled hole, and there is a possibility that the measuring probe may be damaged by gravel during the downward movement. Meanwhile, the method does not give technical suggestion of synchronous measurement of a plurality of holes.
2. The invention name is as follows: a pre-perforating device for a profile soil moisture measuring system; application No.: 201610248040.7, respectively; the patent applicant: china institute of Water conservancy and hydropower science. The invention solves the positioning relation between the punching device and the limiting pipe, but cannot ensure that a subsequently placed measuring probe accurately enters a preset hole, and can also cause the damage of a detection system if gravel exists in the downlink. Also, it does not give any technical teaching for simultaneous measurement of multiple holes.

The fixed connection part 13 is not fixed, but fixedly connected to the output end of the punch driving motor 14, and under the action of the punch driving motor 14, the fixed connection part 13 rotates and rotates the movable connection part 12 through a thread effect, and the length of the thread connection between the movable connection part 12 and the fixed connection part 13 changes during the rotation process of the movable connection part 12, so that the telescopic effect is realized. Therefore, it is necessary to have a rod structure with threads on the outer surface and a tubular structure with threads on the inner surface in the movable connecting part 12 and the fixed connecting part 13. The length of both threads may be defined according to the length of movement of the movable connecting portion 12.
