6.2 Operation
The tractor pto drives the diaphragm water pump. Through the suction basket and the
suction hose water is sucked in from a ditch or a water tanker. Then the water is sent
through a pressure controller (the excess pressure is sent back through an overflow
hose to the ditch or the water tanker) and then through the rotating centre of the
flushing hose reel, after which it sprays out of the nozzle and performs its cleaning
action in the drainpipe. The flushing hose runs from the reel with the drive mechanism
through the guide arm and roller bend into the drainpipe. See diagram fig. 03.
The guide arm can be folded in and out with the aid of a hydraulic cylinder from vertical
to horizontal position and back. The guide arm can be extended and retracted with the
aid of a second cylinder. The flushing hose can be fed through the guide arm and the
roller bends with the aid of 2 rubber wheels driven by a hydraulic motor that are
clamped around the flushing hose. The hydraulic system is designed in such a manner
that both during feeding in and feeding out the reel wants to roll up under slight
pressure, so the flushing hose always winds tightly around the reel. The second section
of the roller bend can be turned to enable cleaning drainpipes in the own bank as well
as in the opposite bank. See diagram fig. 04.
The hydraulic system of the machine features a pressure compensation valve that
sends the excess oil from the tractor directly back to the hydraulic reservoir of the
tractor. That reduces the heat generation of the hydraulic oil. See diagram fig. 04.
