Application of image processing for determination and comparison of the abrasive wear in chisel tines and moldboard blades

Abstract

Determination the wear of tillage tools such as blades has a particular importance that is often achieved by weighing method. The purpose of this study was the usage of image processing methods for determination and comparison the wear of the moldboard blades and chisel tines instead of weighing method and determination the best abrasion resistant material for the blades. In this study three different moldboard blade and chisel tines were used. Blades were eroded in the equal soil conditions at five different stages during 30 hectares plowing. At each stage of abrasion, images were taken from the blades with a digital camera in a domed chamber having a uniform illumination. Images were then processed using Matlab software and the values of wear were determined as a percentage ??of surface and weight. Results showed that there was a significant difference between the blades which proposes the best combination of the structural elements for the blades as 27% C, 26% Si, 1.25% Mn, 0.4% Cr, 0.16% Ni and 0.023% S.
