Substantiation of Installation Parameters of Additional Soil Tilling Implements in Plowing Units due to the Movement of the Furrow Slice on the Surfaces of the Plough Body
The article represents the equation of furrow slice movement along the moldboard depending on the speed of the unit, it characterizes the curvature of the angle trajectory, the gravity force of the furrow slice, the applied traction force and the resistance force caused by rehandling of the furrow slice particles as it rolls up along the moldboard. Analytical expressions are obtained for determining the time of the furrow slice movement along the moldboard, the coordinates of the furrow slice fall on the field surface and the estimation of the fall time. The results can be used in the field of agricultural engineering in the design of reversible ploughs and additional implements for soil surface treatment.
To the problem of cow`s idle milking
The article theoretically confirms the inevitability of cow`s idle milking caused by uneven development of udder quarters and varying duration of cow`s milking in a group. The mathematical dependence of milking machines over-exposure on the udder depending on the number of milking machines used and the time of preparatory-final operations has been determined. To exclude the idle milking the using of milking machine supplied with a device for quaternary control of milking intensity has been offered.The effectiveness of milking machines supplied with devices for quaternary control of the intensity of milk yield has been shown.
