Mechanised irrigation frame for agriculture has secondary irrigation pipe mounted for vertical movement with respect to main pipe by winch

摘要

The irrigation frame (10) has a secondary irrigation pipe (34) mounted for vertical movement under the main pipe (14). The secondary pipe is moved vertically by a hoist (46) with a cable (48) extending over the whole length of the system. The hoist cable is connected to the secondary pipe at regularly spaced points along its length. There can be culture monitors mounted on the secondary pipe, which can also carry chemical dispensers.
