AI Technical Summary

Technical Problem

Existing soil sensor probes are easily damaged when they come into contact with hard objects when inserted into the soil, resulting in low safety, affecting service life, and the lack of protective structure affects fertilization accuracy.

Method used

An outer protective cone plate is installed outside the probe of the soil nitrogen, phosphorus and potassium sensor, and a V-shaped plate is installed inside it. The outer protective cone plate is rotated by an extension arm driven by a motor to avoid soil adhesion affecting the detection results. At the same time, the sensor is moved by a lead screw driven by a motor to expand the detection range.

Benefits of technology

It improves the probe's protective capabilities, ensures fertilization accuracy, avoids damage caused by contact with hard objects, extends its service life, and can expand the detection range as needed, thus improving its practicality.

Abstract

The utility model relates to the technical field of soil fertilization, in particular to a vehicle-mounted soil water and fertilizer conveying probe which comprises a rotating arm, an outer protection cone plate is fixedly mounted at the bottom of a mounting shell, and a V-shaped plate is fixedly mounted at the bottom of an inner cavity of the outer protection cone plate. The outer protection cone plate is arranged outside the probe of the soil nitrogen phosphorus and potassium sensor, the protection capacity for the probe can be improved, the V-shaped plate is arranged in the outer protection cone plate, and the third motor is started to drive the extension arm connected with the output shaft of the third motor to drive the outer protection cone plate to turn over, so that the detection accuracy is improved. Therefore, the soil can be prevented from being attached to the inside of the outer protection cone plate to influence the result of soil re-detection, the fertilization accuracy is ensured, and the problems that in the prior art, in order to ensure the fertilization accuracy when water and fertilizer are sprayed to the soil, a soil sensing probe structure is usually arranged on a tumbrel, but the structure lacks protection, and the fertilization accuracy is poor are solved. When being inserted into the soil, the anti-collision device is easy to damage due to touching hard objects, the safety is low, and the service life is influenced.
