中心支轴式喷灌系统又叫时针式或旋转型喷灌机,这种喷灌装置,只有一根喷灌支管,安装在若干个能自动行走的塔架上,支管的一端铆在固定的中心支轴支架上,与水源(水井或给水栓)联接,另一端则绕着中心支轴作缓慢的间歇旋转,在喷灌支管上装有喷头,不断喷灌作物。中心支轴式喷灌装置,是在1952年由美国人富兰克·佐巴奇(Frank Zybach)研制的,并获得专利,以后由凡尔蒙(Valmont)公司不断改进完善,成为近十年发
Spindle irrigation system, also known as the center-axis or rotary rotary sprinkler, the sprinkler irrigation device, only a sprinkler branch, installed in a number of automatic walking tower, branch pipe riveted at one end of the fixed center pivot bracket , Connected to a water source (water well or water supply plug), and the other end is rotated slowly and intermittently around the central support shaft.
