Sampling device of soil humidity sensor

Abstract

The invention discloses a sampling device of a soil humidity sensor. The sampling device includes a fixed seat, the top of the fixed seat is provided with a hydraulic cylinder, the fixed seat is internally provided with an accommodating cavity, the output end of the hydraulic cylinder is provided with a vertically downward telescopic rod, the telescopic rod extends into the accommodating cavity and is connected to a drive motor, the bottom of the drive motor is equipped with a connecting rod, the outside of the connecting rod bottom is provided with a limit plate, the output end of the drive motor is connected to a vertically downward rotating shaft, the bottom of the rotating shaft is connected to a rotating limiting block, the bottom center of the rotating limiting block is in fixed connection with a vertically downward drive rod, and the bottom of the drive rod is connected to a sampling head. The sampling device of a soil humidity sensor provided by the invention has a simple overall structure, and not only can apply a force to the drive rod and the sampling head automatically during sampling, and save manpower, but also is convenient for taking out of a sample thoroughly by dismantling the sampling head, can prevent leaving residue, and is more convenient to use.

Description

technical field [0001] The invention relates to the field of sampling devices, in particular to a sampling device for a soil moisture sensor. Background technique [0002] Soil moisture sensor, also known as soil moisture sensor, soil moisture sensor, soil moisture sensor, is mainly used to measure soil volumetric moisture content, soil moisture monitoring, agricultural irrigation and forestry protection. [0003] In the existing sampling devices for soil moisture sensors, most of the sampling devices need to manually press the top of the sampling device to allow the sampling head of the sampling device to enter the soil through the pressure of the hand when sampling. , it is more labor-intensive, and after sampling, the soil in the sampling hole is not easy to take out, and there is often a phenomenon that residues are left inside. For this reason, we have designed a sampling device for soil moisture sensors to solve the above problems. Contents of the invention [0004]...
