Method and apparatus for spreading fertilisers by centrifugal fertiliser spray

摘要

The centrifugal fertiliser spreader has several counter rotating bladed impeller discs on vertical axes. It deflects the fertiliser particles, projected in a forward direction (125) beyond the front (119) of the storage hopper (101) into one (126), which does not extend in front of it. Thus the distance (W), for which particles are projected at right angles to the travel direction (111), remains nearly constant. constant. The deflection pref. takes place to either side.
