Canola Covers
Canola covers are used to restrict spools
being used to meter small seed, such as
canola.
These covers are similar to the 100%
spool cover except for a hole in either
the right or left side.
The metering spool length of 75mm is divided into two sections. One
section is 25mm wide and the other is 50mm wide. The canola cover
effectively blanks off the 50 mm section and meters the seed through
the hole which lines up with the 25mm section of spool. This hole is
raised so that seed with the ability to run remains checked and will
not flow through the metering unit unless the spools are turning. By
using these covers while metering seed such as canola or sorghum a
higher spool rpm can be maintained for a more consistent flow of
product.
Blocking Air Streams not in Use
For sowing activities where primary lines are not in use it is
important that the air is blocked and is directed to the air streams in
use.
Disconnect primary lines not in use at
the breakaway connections on the air
seeder. Fit camlock blanking plugs to
the lines not being used so that air
cannot escape.
When the camlock plugs are put in place in the lines not in use the
air cannot escape, however, if this is the only method used to block
the air stream, air can transfer within and between the metering
units causing higher than required air volume in the lines in use,
resulting in inconsistent sowing rates and possible force feeding.
To overcome this unwanted transfer of air, ‘sponges’ must be used in
all metering unit lines not in use.
This is achieved by opening the bottom
swing away door on each metering unit
and feeding a ‘sponge’ (pictured) up into
the cavity between the flow through tubes
of air streams not in use.
This will prevent air transfer within and
between metering units and a balanced
pressure equalised system will be
achieved.
