Checklist for optimising the lifting quality
525 / 564
Root fracture
– Lift deeper
– Reduce damaged beet lifting speed
– Check/replace lifting shares
– Reduce infeed conveyor rpm
– Reduce strainer wheel rpm
– Set sliding ring on pig tails downwards
– Install sliding grids instead of pig tails
– Reduce unloading height
Too much soil tare
– Lift flatter
– Increase shaking share rotational speed
– Reduce lifting speed
– Set roller position higher
– Increase the distance between guide grids and
strainer wheels
– Increase strainer wheel rpm
– Set sliding ring on pig tails upwards
– Install pig tails instead of sliding grids
Lost beets
On lifting unit:
– Increase share distance
– Set share angle flatter
– Set roller position lower
– Check the guide rods on the share body (lost/broken)
– Install larger lifting shafts (Ø) if the beets are very
small
– Reduce infeed conveyor – lifting shaft – strainer
wheels distance/height
On the cleaning unit:
– Reduce infeed conveyor – lifting shaft – strainer
wheels distance/height
– Check strainer wheel pig tails (lost/broken)
– Reduce the distance between guide grids and strainer
wheels
– Reduce distance between inner grids and strainer
wheel
For machines with rubber-defoliator
In the case of lifting faults check/change the settings in the following sequence:
Remaining beet leaves
– Set combined shaft/cleaning shaft deeper
– Increase combined shaft/cleaning shaft rpm
– Reduce lifting speed
