Rational reduction of metal complexity in the design of wide cut sprinklers

Abstract

One of the criteria for assessing the quality of different types of designs of irrigation machine is a constructive coefficient mass.Тhe smaller it is the better construction. The constructive mass coefficient of the machines with varying diameters pipeline is much lower than those machines with a constant diameter. The constructive mass coefficient of sprinklers with hard farm ("Kuban") is lower than in machines with the cable suspension ("Frigate"). To assess the quality of the farm was introduced the coefficient of metal equal to the ratio of the total perimeter of the angle on the span to the length of the span. The conducted research allows highlighting the main directions of reducing metal consumption of wide cut sprinkling machines: increasing the span length between the supporting trucks, reducing the weight of the water bearing pipeline through the optimization of farm, and application of the pipeline with variable pipe diameter along the length of the machine.
