Abstract

The invention relates to a geometric structure of a workpiece of a vehicular sensor used for measuring soil moisture and compactness, in particular to a conical soil-engaging component with an abrasion-resistant geometric structural surface. The component consists of a substrate and bionic geometric structure units distributed on the surface of the substrate and is characterized in that: the bionic geometric structure units comprise a convex hull type, a concave pit type, an annular convex rib type, an annular concave rib type, a spiral convex hull type, a spiral concave pit type, a spiral convex rib type and a spiral concave rib type. The component aims to solve the problem of the abrasion of a conical head of a sensor when the soil moisture and the compactness are measured. The bionic geometric structure units and the substrate are of an integrated structure. The component is made of 1Cr18Ni9Ti, Cr15 or Si60Mn2.

Description

technical field [0001] The invention relates to a cone-shaped part for agricultural machinery processing or measuring soil parameters, in particular to the design of a sensor cone head, which is a surface with a wear-resistant geometric structure, and is mainly used in the technical field of soil processing and soil measurement machinery design. Background technique [0002] The measurement of soil moisture and compactness requires the sensor to work in the soil for a long time, and the wear is serious, which belongs to the type of abrasive wear. This wear is the main cause of component failure. As a result, the measurement accuracy is reduced and the measurement data is inaccurate. At present, in order to reduce this wear and tear. People mainly focus on improving the working conditions, improving the wear resistance of materials, developing higher wear-resistant materials, the influence of soil on wear resistance, and the exploration of abrasive wear mechanisms. These s...
