Dependence of the bending force on the morphology of cotton stems and on the parameters of the stalk bender

Abstract

The object of study is the process of bending the cotton stalk in an upright position to the side, and the technological design parameters of the bender which performs it. Bending the stalks to the side edge, in the direction of the aggregate movement, is the initial process of the proposed technology. The quality of the process is assessed by the fact that the stalks are laid on the bottom of the lateral axis along its axis of symmetry. The placement of the stalk at an angle of up to 30 ° to the axis of symmetry satisfies the requirement. Then the buried cotton stalks will not interfere with the agro-measures of inter-row cultivation. The research used the principles of theoretical and agricultural mechanics, higher mathematics and methods of mathematical planning of experiments. The process of bending the cotton stalk to the side, and the amount of force acting on the stalk by determining the stiffness, size, characteristics of the stalk, as well as the mounting angle and height of the stalk, were determined. The results were analyzed by constructing their graphs. The effects of the centering height and angles of the bender on the amount of force bending the stalk are determined by the experiment. As a result of theoretical and experimental studies, the mounting height of the bender on the ridge surface for laying the stalks at a small angle to the axis is h=15 cm, angle relative to the direction of movement γ=43° and the radius of curvature of the bender r=96 mm was determined.
