Abstract
PURPOSE: To enable sprinkling over a wide area by using a pump of small capacity, by dividing piping of discharge side of a pump, providing a magnetic valve in each valve, connecting a sprinkling nozzle to discharge side of valves and opening and closing the valves successively at a specified cycle.
CONSTITUTION: When sprinkling is started, a normally opened contact 8 of a sprinkling start timer T is closed, and a pump 1 starts operation. At the same time, current is applied to the first timer T1 through the first magnetic valve V1 and its normally closed contact 10a, and liquid fertilizer, etc. is sprinkled from a sprinkling nozzle 6a. Since the second and succeeding magnetic valves V2, V3... are closed, no sprinkling is made from sprinkling nozzles 6b, c.... When the set time lapses, the contact piece is switched to normally opened contact 10b side, and the first magnetic valve V1 is closed, and current is applied to the second magnetic valve V2 through the second timer T2 and its normally closed contact 11a, and sprinkling is made from the second sprinkling nozzle 6b. Thus, timers operate successively and sprinkling is made from corresponding sprinkling nozzles.
