Abstract

The invention relates to a probe tube for measuring deep-soil humidity and belongs to the technical field of soil testing equipment. The probe tube comprises a tube body, spiral blades are distributed around the tube body, an opening is formed around the tube body, a probe is arranged inside the opening, symmetric pressurizing devices are respectively arranged at upper and lower ends of the opening and positioned in a tube wall, elastic materials are arranged on one opposite sides of the pressurizing devices respectively, conical bodies are arranged on one opposite sides of the elastic materials, and one end, with less radius, of each conical body faces the middle of the opening; a probe is arranged inside the tube wall, faces the conical bodies and is connected with a stepping motor, the pressurizing devices and the stepping motor are connected with a controller, and a switch is arranged on the upper portion of the tube body and used for sending working instructions for the stepping motor and the pressurizing devices to the controller. The probe tube can measure moisture content in deep soil, and the surfaces of the probes are less prone to being affected by soil of previous measurement during each measurement process, so that testing accuracy is improved.

Description

technical field [0001] The invention relates to a probe tube for measuring depth soil moisture, belonging to the technical field of soil detection equipment. Background technique [0002] Soil moisture content is one of the important factors affecting crop yield and water conservation. Soil moisture is important for the development of irrigation schedules, the evaluation of water and solute flow, and the division of latent and sensible heat from net solar radiation. Soil moisture is important in hydrology as an important parameter in predicting water depletion patterns. In the atmospheric numerical model, the simulation of land-atmosphere interaction and other parameters of the water-air cycle require the measurement of soil moisture, and the verification of satellite remote sensing evaluation also requires direct measurement of surface soil moisture. The measurement of soil moisture can be expressed by the determination of soil moisture content and soil moisture potenti...
