Abstract

Sprinklers created in the Soviet period and still widely used in the fields today, in many respects no longer meet modern requirements, do not guarantee high-quality watering and reliable operation. It is necessary to develop new design principles, concepts, new techniques and approaches, to clarify the required parameters and characteristics. It is important not only to modernize and restore the irrigation equipment in operation, but also to produce new reliable, high-quality machines. One of the current trends in the design of sprinklers is the principle of resource conservation. The article defines the directions of improvement of structural and technical parameters, presents the design concept depending on the operating conditions. The ways of reducing the metal consumption, and consequently the cost of machines, are considered. Obvious ways to reduce the metal consumption of machines include increasing the span between the trolleys and reducing the weight of the truss water belt by improving the design. Optimization of the truss water belt allowed to increase the span length by 22.1-33.8% with a slight increase in weight by 5.8-15.1%.

从节约资源的角度设计洒水车
苏联时期发明的洒水器至今仍广泛应用于田间,在许多方面已不能满足现代要求,不能保证高质量的洒水和可靠的运行。有必要开发新的设计原则、概念、新的技术和方法,以明确所需的参数和特性。重要的是不仅要现代化和恢复运行中的灌溉设备,而且要生产新的可靠的、高质量的机器。以资源节约为原则是当前洒水车设计的趋势之一。文章明确了结构参数和技术参数的改进方向,提出了根据运行工况的设计思路。考虑了减少金属消耗,从而降低机器成本的方法。减少机械金属消耗的明显方法包括增加小车之间的跨度和通过改进设计来减轻桁架水带的重量。桁架水带优化后,跨度增加22.1 ~ 33.8%,重量增加5.8 ~ 15.1%。
