Comprehensive assessment of the degree of flooding of soil-cutting working bodies (on the example of plow shares)

Abstract Studying the wear process of shares operating in an abrasive environment on the soils of meadow, light and typical gray soils, the parameters of the limiting state are analyzed and it is revealed that the main parameters that contribute to the rejection of shares are the parameters of the occipital chamfer. It is also noted that maintaining a generalized index of blade rejection creates an opportunity to generally assess the degree of wear of the blade, for all changing parameters at the same time and quantify it. This facilitates the assessment of the quality state of the wear of the blade, not only of an individual, but also of groups of compared working bodies. According to this indicator, by conducting a comparative assessment of various designs and working conditions (or tests), it is possible to determine the weakest of them in terms of bluntness or the most abrasive working environment of the working bodies.
