Soil effect on the blade of working bodies of tillage machines

Наведено аналіз впливу ґрунту на ріжучі елементи робочих органів ґрунтообробних машин та розглянуто фактори, що забезпечують зниження навантажень. The article describes the main aspects of uneven wear of the blade working bodies of tillage machines. The main goal of the research is to outline the reasons that affect a higher intensity of top wear of the cutting element. Their analysis revealed the formation of compacted soil volume and its impact on the character wear top and bottom faces of the blade cultivating working body plows, cultivators, harrows difficult. Presented justification uneven wear of the front and rear faces of the blade, it is shown that under the back edge of ground friction on steel largely replaced by friction against the ground soil, which causes an increase in the coefficient of friction. The research results can be used to improve the quality of tillage, to reduce the traction effort, to increase operational stability of working bodies of tillage machines
