4 Assembly and operation
4.1 Assembly
The DR1500 feeding system is delivered in the following pre-mounted assembly
groups:
• Drive unit
• Feed pipe
• Feed discharge points
• Feed supply
• Control unit
4.2 Functional description
From the feed silo, the feed reaches the feed pipe(s) via a feed container made of
corrosion-proof stainless steel. One or two loops can be supplied with feed, depending
on whether a single or dual feed container is used.
A feed pipe consist of a pipe system made of strong galvanised steel pipe and 90°
corners (turns) made of plastic or stainless steel. A conveyor chain resp. rope on which
equispaced carrier plates made of plastic are spray-painted runs in this pipe system.
Between these discs, the feed is transported through the pipe system to the individual
discharge points. Due to pipe and chain or rope couplers the system forms an endless
unit.
The system can either run with a conveyor rope or chain. The conveyor chain or rope
is driven by a drive unit made of stainless steel with integrated tensioning device for
chain and/or rope.
At the discharge points in the feed pipe, automatic feeders are filled via draw-offs with
sliding valves and drop tubes or feed troughs via volume dispensers and drop tubes.
In the standard version, the system fills each individual feed discharge point after the
other until the sensor after the last feed discharge point switches off the system.
In most cases, the feed is supplied directly by means of a feed container via a sliding
valve from the silo.
Furthermore, there is a possibility to combine a Flex-Vey-feed-transport system by Big
Dutchman with a DR1500. Here, the feed is transported with a feed auger via a hopper
into the feed container.
