Cleaning type soil detection system with angle adjusting function

Abstract

The invention relates to a cleaning type soil detection system with an angle adjusting function. The system comprises a detection device, wherein the detection device comprises a main body, a probe, adisplay screen and at least two control keys; the system further comprises an adjusting mechanism and a cleaning mechanism, wherein the adjusting mechanism comprises a mounting base, two connecting shafts, two connecting casings and two limiting assemblies, and the cleaning mechanism comprises a driving assembly, a first spring, a lifting ring, a mounting pipe, a cleaning brush, a rotating shaft,two winding reels, two mounting bearings, two supporting rods and two connecting wires; and each limiting assembly comprises a mounting casing, a limiting rod, a second spring and at least two limiting grooves. According to the cleaning type soil detection system with the angle adjusting function, the angle of the main body can be adjusted through the adjusting mechanism, the convenience of operating a soil hygrometer by an operator is improved; and the probe can be automatically cleaned through the cleaning mechanism, and therefore, convenience in cleaning the soil hygrometer is improved.

Description

technical field [0001] The invention relates to the field of soil detection equipment, in particular to a clean soil detection system with an angle adjustment function. Background technique [0002] The soil moisture meter is a portable instrument for measuring soil moisture. It is easy to carry. Moisture is the main factor determining the dielectric constant of soil. Measuring the dielectric constant of soil can directly and stably reflect the real moisture content of various soils. Using the most popular international field test soil moisture principle -- frequency domain reflection principle, the instrument emits electromagnetic waves of a certain frequency, the electromagnetic waves are transmitted along the probe, and return after reaching the bottom to detect the output voltage of the probe. Due to the change of soil dielectric constant Depending on the moisture content of the soil, the soil moisture content can be calculated from the relationship between the output vo...

Problems solved by technology

[0003] The probe of the soil moisture meter in the prior art is fixedly connected to the main body. When the operator inserts the probe into the soil, the main body cannot adjust the angle, which reduces the convenience for the operator to operate the soil moisture meter. Not only that, the prior art After the soil moisture meter is used, the operator needs to manually clean the probe, which further reduces the convenience of using the soil moisture meter.
