| 移动式喷灌系统 Portable system 除水源外，动力机、水泵、干管、支管和喷头等都是可以移动的，因而可在一个灌溉季节里在不同地块轮流使用,提高了设备利用率，并可节省单位面积投资，但工作效率和自动化程度低。常用的类型中，有的是动力机和水泵装在手推车或手架上的轻、小型喷灌机，其喷头装在轻便三角架上，通过软管同水泵连接;有的是将水泵同喷头装在手扶拖拉机上的小型喷灌机，由手扶拖拉机的动力输出装置驱动水泵作业;有的是装在大、中型拖拉机上的双悬臂式喷灌机。移动式喷灌系统适用于灌溉次数较少的大田作物和小块地段。 In addition to water sources, power machines, pumps, trunk pipes, branch pipes and sprinklers are movable, so they can be used alternately in different plots in an irrigation season, which improves the utilization rate of equipment and saves investment per unit area, but the work efficiency and automation level are low. Among the commonly used types, some are light and small sprinkler irrigation machines with power machines and pumps mounted on trolleys or scaffolds, whose sprinkler heads are mounted on portable triangles and connected with pumps through hoses, and others are small sprinkler irrigation machines with sprinklers mounted on walking tractors, which are driven by power output devices of walking tractors. It is a double cantilever sprinkler mounted on large and medium tractors. Mobile sprinkler irrigation system is suitable for field crops and small plots with less irrigation times. 此外，在有条件的地区，还可发展自压喷灌。其优点是可以利用水的自然落差，不需动力机和水泵，设备简单，操作方便，使用成本低。 In addition, self-pressure sprinkler irrigation can also be developed in areas where conditions permit. The utility model has the advantages of utilizing the natural drop of water, needing no power machine and water pump, simple equipment, convenient operation and low cost. |
