Investigation of tillage elements of agricultural machinery

Abstract

The efficiency of agricultural activity is significantly influenced by the condition of power machines used in the agricultural production. Among others, the formation and maintenance of suitable soil-conditions play a very important role in obtaining the desired harvest yield. Many types of wear have been recognized such as abrasive, erosive, corrosion, oxidation etc. The abrasive wear in agriculture equipments is the most common problem. The tillage elements are exposed to an extraordinary high load and a significant wear, therefore it is necessary to investigate the relationship between their active layer and durability. Abrasive wear is probably the most significant cause of mechanical damage of equipment components coming in contact with abrasive bodies. The purpose of our research work is to change the old, worn cultivator tines to tines having a longer durability; hot metal powder spray fusing has been used in order to realize our aim. The products made by us will be used in the agricultural production in the future therefore the type of layer build-up technology to be used during the production can be determined. As a cultivator is equipped with a lot of cultivator tines, the expenses can significantly be decreased by the use of cultivator tines made by a well-chosen layer build-up technology and a higher yield/agricultural area can be obtained during the cultivation.
