Determining the Forces Acting on the Working Tools of Rotary Tiller Drums

摘要

The process of rotary tilling consists of the working tools of the rotary tiller isolating a chip from the soil mass, deforming it, breaking it up and throwing it in the direction of rotation. During this the wedge shaped section of the working tool, begins to compress the upper part of the chip and then crumples it and tears it from the mass. The problem is to find these parameters and their relation of change in time to the system of operation, the shape of the operating tool and soil conditions (type of soil and its physico-mechanical properties). These data are necessary for calculation of the working tools in respect to strength and rational plotting of the technological process of working soil. (Author)
