THEORETICAL INVESTIGATIONS OF STRAW PARTICLES MOTION WHEN LEVELING HAY ROLLS
DescriptionOne can see some density irregularity within the roll in the baler with a chamber of constant volume. We have found out that the maximum density of hay roll width (the baler width) is observed in the middle part. This is due to the shape of the hay roll entering the baler. To even the hay rolls they have mounted some rotating disks having some inclined spring pins above the baler. To improve the roller distribution the disks above the baler have been pushed forward forming a tapering gap. The evening discs rotating above the moving roll will cause some relative motion of hay particles. The interaction of the evening disks with the hay roll in the vertical plane will be determined by the elasticity of the hay roll and the weight of the frame with the disks. We have studied the trajectories of hay particles motion with the help of MathCad program. We have had the following initial parameters: the degree of compaction (decrease of the roll height when evening), the friction coefficient, the angle rate of the evening disks, the number of pins and the speed of the hay roll. As a result we have got the trajectories of the hay particles motion when the evening disks functioning. The analysis of the trajectories has allowed to establish some basic parameters of the evening device such as the distance of 0.15…0.2 m between the pins; the degree of compression while evening 20...25 %, the angle rate of the evening discs 23...30 rad / s and the diameter of the evening disc 0.74 m. The application of the evening device in the form of the disks with pins provides a uniform distribution of hay particles edgewise of the baler ensuring preliminary hay roll seal press before passing to the baler pressure chamber that contributes to getting the rolls with larger mass and a uniform distribution of hay density inside the roll

THEORETICAL STUDIES OF A MILKING DEVICE WITH AN OVERHEAD MILK REMOVAL FROM THE COLLECTOR
DescriptionThe aim of the research was the theoretical justification of the main design-technological parameters of the experimental milking apparatus with an overhead milk removal from the collector. The milking machine comprises teat cups, collector, pulsator, milk hose, and vacuum. The manifold is formed with an upper withdrawal of milk by means of a vertically mounted suction tube. The upper end of which is located in the output region of the milk tube, and the bottom – in the bottom of the milk camera collector. The article presents the results of theoretical studies on the analytical substantiation of structural and technical parameters of the milking machine. It presents graphic dependences characterizing the convergence of results of theoretical and experimental studies of the milking machine
