Soil detection probe with cleaning function

Abstract

The invention discloses a soil detection probe with a cleaning function. The soil detection probe comprises a mounting shell, a probe and a cleaning mechanism. The probe passes through an inner cavityof the mounting shell. The cleaning mechanism comprises a first cleaning brush for primarily cleaning the probe, a second cleaning brush for sufficiently cleaning the probe again, and a cleaning driving mechanism for driving the probe to move back and forth relative to the first cleaning brush and the second cleaning brush for cleaning; the first cleaning brush and the second cleaning brush are arranged in an inner cavity of the mounting shell and are attached to and surround one end, located in the mounting shell, of the probe; the first cleaning brush is arranged at the end, close to the soil, of the mounting shell, and the second cleaning brush has a smaller cleaning gap relative to the first cleaning brush. The soil detection probe can automatically clean oxide, rust, corrosives and the like on the metal strain gauge of the probe, the sensitivity and accuracy of the metal strain gauge are kept; meanwhile, the service life is prolonged.

Description

technical field [0001] The invention relates to a humidity detection device, in particular to a soil detection probe with a cleaning function. Background technique [0002] Intelligent irrigation with automatic control can improve the level of irrigation management, change the arbitrariness of human operation, reduce irrigation labor, reduce management costs, and maximize the benefits of irrigation. Among them, the commonly used control methods in intelligent irrigation control systems are: collect data (such as relative humidity) through sensors (such as soil moisture sensors), and transmit the data to the processing system for analysis and comparison by the processing system. When the collected data When the value is less than the normal value (corresponding to the moisture required for crop growth), it indicates that there is a lack of water in the soil, and the processing system sends irrigation instructions to the irrigation actuator to increase the humidity in the soil...

AI Technical Summary

Problems solved by technology

Among them, the main working element of the probe of the soil moisture sensor is a metal strain gauge, the metal strain gauge is arranged on the probe, and the probe is always inserted in the soil, and is in contact with the soil for a long time, so that it is easy to contact with the air in the soil, Oxidation of moisture and trace elements, etc., leads to rust, making the data measured by the metal strain gauge inaccurate
