| 移动式喷灌系统: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.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. Mobile sprinkler system: except for the water source, the power machine, water pump, main pipe, branch pipe and nozzle can be moved, so they can be used in turn in different plots in one irrigation season, which improves the utilization rate of equipment and saves the investment per unit area, but the working efficiency and automation degree are low. Some of the commonly used types are light and small ones with the power machine and water pump installed on the trolley or hand frame The sprinkler head is installed on a light tripod and connected with the water pump through a hose; some are small-scale sprinklers that install the water pump and the sprinkler head on the walking tractor and drive the water pump by the power output device of the walking tractor; some are double cantilever sprinklers installed on the large and medium-sized tractors. The mobile sprinkler system is suitable for the field crops and small areas with less irrigation times. In addition, the It has the advantages of utilizing the natural drop of water, no need of power machine and water pump, simple equipment, convenient operation and low cost |
