Centrifugal fertilizer spreader

摘要

The spreader has two rotary propelled centrifuge disks, on which throw shovels are arranged. Both the normal fertilization with flat dropping strewing flanks and the border strewing with steeply dropping strewing flanks are feasible. During the transition of normal to border strewing the throw shovels are selectably switched. Rear walls of the throw shovels have sections which are adjustably arranged in relation to each other so that the outside of the sections does not participate in the centrifuge effect. The throw shovels have different effective lengths arranged on the centrifuge disk (11). Behind the front rear wall (115) of the throw shovel (112) an upright rear wall (116) is provided having a shorter effective length than the rear wall and arranged before it. The rear wall of the throw shovel has an opening created by adjusting the internal section (115') of the front rear wall of the throw shovel so that supplyable material can be distributed.
