Analysis of the vibratory cultivator operation

Vibration can significantly reduce the pulling force of machines. The crushing of the soil increases with the frequency of vibration of the organ, and it was found that the size of the pieces of soil depends on the ratio of the speed of the aggregate to the frequency of vibration of the organ. In addition, traction and fuel consumption are reduced compared to machines without vibrating implements. Reduced tractive effort is the most important indicator of the effectiveness of the use of vibrating tools. The purpose of the study is to study the effect of applying vibrations at different frequencies to a cultivator on its performance, as well as oscillatory motion at two frequencies and with constant amplitudes on the traction force of the working body and soil properties. It can be noted that the effect of vibration frequency on tractive effort is more important than the depth of tillage. These two factors are the main and most significant in terms of tractive effort. Working depth also has a significant effect on tractive power. It increases to 54% with an increase in the working depth from 100 to 200 mm. The result is the same with a depth of 300 to 400 mm. An increase in tractive effort occurs due to a higher additional soil pressure and an increase in frictional forces in the "soil-metal surface of the working body" system.
