喷灌机的使用量大面广,和其它农业机械相比,喷灌机在一年内的使用时间较长,在我国大部分地区,每年约需使用2至4个月(1200—2500小时/年左右),而其它农业机械每年使用的时间均较少,如康拜因联合收获机每年只使用5—15天(约40～120小时/年),拖拉机美国约为500小时/年,日本约为290小时/年(轮式),苏联约为1500～2500小时/年。其次是喷灌机的工作条件恶劣,经常住潮湿泥泞、风侵日晒的情况下工作,有的还只能长年露天放置。另外,喷灌机具能够一机多用(如施化肥、农药、除
Sprinklers are used in a wide range of sizes. Compared to other agricultural machines, the sprinklers have been used for a long time in a year. In most parts of our country, it takes about 2 to 4 months (1200-2500 hours / year) ), While other agricultural machines use less time each year, such as Combine harvesters only 5-15 days (about 40-120 hours / year), tractors USA about 500 hours / year, Japan about 290 hours / year (wheeled), the Soviet Union is about 1500 ~ 2500 hours / year. Followed by poor working conditions of irrigation machines, often live in wet muddy, wind and sun in the case of work, and some can only be placed in the open air for many years. In addition, irrigation equipment can be a multi-purpose machine (such as fertilizers, pesticides, except
