Plough hitch parameters for smooth tails

Abstract

Abstract Qualitative and energy performance of a plough largely depends on the parameters of the plough linkage mechanism. The aim of the research is to substantiate the parameters of plough linkage for smooth sloughing, which turns the layers within its furrow to a tractor of 1.4 classes. In researches methods of classical mechanics are applied. The effects of the field relief on the plough’s angular vibrations leading to changes in the depth of the hull stroke and its power load are studied. The dependencies for determining the plough linkage parameters are obtained. Theoretical studies have shown that the plough’s stroke uniformity and traction resistance are significantly affected by the longitudinal distance between the bodies, the vertical coordinate of the plough’s lower fingers and the height of the attachment triangle.n order to ensure the required uniformity of running at the working depth and minimum traction resistance, the following parameters of the attachment to tractors of class 1.4 are set: rack height and base width of the attachment triangle respectively 0.55-0.56 m and 0.70-0.75 m, the distance between the lower pins of the attachment and the plough support surface 0.45-0.50 m.
