This
chassis constitutes a major component of our chain-type fixed weed
screen cleaning systems installed at open-source water intakes of
some irrigation pumping stations in Egypt. It is formed of a steel
framework comprising two vertical sides, three transverse beams and
a chassis front. It provides the weed screen cleaning machine with
hinged fixation. It is also meant to carry the horizontal belt conveyor
that will be used at a later phase to transfer weeds outside the station
platform via an inclined belt conveyor.
Vertical
Sides:
Made
of UPN-260 beams, each side is equipped with various supports:
•
two supports for the upper transverse beams
•
a support for the lower transverse beam
•
a machine support located at the top of the side
•
90x90x9 angles to fix the chassis front
•
front & rear 20-mm thick plates to allow for accurate vertical
side fixation
Transverse
Beams:
Three
transverse beams connect the right and left vertical sides. The two
upper UPN-160 beams are meant to carry the horizontal belt conveyor.
A lower UPN-260 beam is used to fix the upper ends of the weed screen
panels.
Chassis
Front(slider):
The
chassis front is a framework comprising 90x90x9 steel angles mutually
engaged and welded. It is further ribbed longitudinally and transversely
with a screen of steel strips. Covered with a 6-mm thick steel plate,
it is fixed to the chassis with bolts at an inclination equal to that
of the weed screen. Actually the chassis front works as a slider along
which weeds slide as the rake leaves the weed screen. Weed sliding takes
place again when the rake discharges collected weeds upon disengagement
by bend sprockets for eventual handling by belt conveyors.
