Abstract
The influence of forces and moments on a plowing walking tractor is considered. The main regularities in calculating the component forces of resistance to the tool in the mode of digging and changing the treatment depth are determined. It is established that physical efforts of the operator, aimed at regulating the depth of soil treatment, significantly exceed the permissible.
Highlights
Units based on motor blocks differ from traditional ones by rigid fixing of the tool to the frame of the motor block
Based on the analysis of the reference literature, it is established that plowing walking tractors have distinctive features that need to be considered when performing calculations of design parameters
The object of work is to conduct an analytical foundation of the design parameters of plowing walking tractors and of their influence on the operator's physical participation in the traction movement
Summary
Units based on motor blocks differ from traditional ones by rigid fixing of the tool to the frame of the motor block. Changing of the treatment depth in this case is carried out by pitching the whole unit. The operator moves the control bars in a vertical plane. The operator applies force to the control bars in the longitudinal and vertical directions, which leads to his rapid fatigue [1]
