Singulating Belts
The singulating belts (item 2, fig 10) consist of one fast belt and one slow belt
arranged in a V-format. The action of the fast and slow belts sorts the potatoes into a
continuous, single line before feeding them onto the trough belt. The belts on the RH
unit are each fitted with a proximity sensor (item 1, fig 12) which monitors their
speed.
The sensor (item 2, fig 12), via the motor ON/OFF valves (item 3, fig 12), controls the
flow of seed. A continuous, single line of potatoes should be presented to the trough
belt. To achieve this the sensor can be adjusted for position and range.
To adjust the position, loosen the clamp bolt and slide the sensor along the support
bar (item 4, fig 12). The sensor should be positioned to allow a row of seed to build
up in front of the seed placement belt.
The rubber curtain (item 5, fig 12) is designed to restrict the flow of singulated seed
to the trough belt. The curtain is raised / lowered by loosening the locking knob (item
6, fig 12) and rotating the curtain mounting. Do not restrict the flow too much as this
can result in misses when planting.
Trough Belt
The trough belt (item 1, fig 13) and seed placement belt (item 2, fig 13) work together
to deliver the row of seed potatoes to the openers. The sensor (item 7, fig 12)
monitors the speed of the belts which, along with the forward speed of the planter,
ensures even spacing of the seed in the ground.
The sides of the trough belt are angled upwards by the extension panels (item 3, fig
13) creating a trough that keeps the potatoes centred. The panels are adjustable to
create different width troughs depending on seed size and should be set to prevent
one potato overtaking another which could result in ‘doubles’. To adjust, loosen the
bolts x3 (item 4, fig 13) and slide the extension panels to the required position.
