Abstract
The physical essence of the process of interaction of the system "operating element of a soil tilling machine – soil" in different conditions of its operation has been considered. It gives the opportunity to find out methods of reducing energy consumption during soil cultivation. The dependence of traction resistance of the operating elements of tillage machines on the conditions of their operation was revealed. It is determined that the process of sticking soil on the surfaces of operating elements is one of the reasons for the increase of traction resistance. The analysis of modern methods and techniques to reduce the amount of soil sticking on the working surfaces of the tillers was carried out. The nature of the adhesion of soil particles to the cutting elements and the surface of the working surfaces of the tillers is taken into account from the point of view of the study at the macro and micro levels.
To study the process of soil sticking, a serial Hardox 400 steel operating element, coated with Kocetal K300 and high molecular weight polyethylene and basalt fibre was selected.
The values of changes of soil sticking index on the working surface of the deep tillers from the speed of movement of the operating element of tilling machine and the applied coatings of different materials, and the statistical characteristics of the measurements were obtained. The nature of the dependence and the magnitude of the horizontal component of the force of traction resistance of the tiller on the speed of its movement, the absolute humidity of soil, the particle size of the loamy soil and on the depth of its cultivation were determined.
