Sprinkler with hose laid on ground - has winding drum hydraulic drive pressurised using water which flows through rotary pump acting as drive motor

摘要

The sprinkler has a long feed hose which is laid on a field and slowly wound up onto a driven hose drum set up at the edge of the field. The drive of the hose drum (3) is powered by water being delivered into the feed hose (2). A drive machine (19) which is set into rotation by the flow is built into the flow of the water. The drive machine is a rotary pump which acts as a motor and is axially connected with a hydraulic pump (26) which subjects a hydraulic circuit to pressure to move the hose drum.
