Abstract

A core destroying machine utilizes a single processing rotor cooperable with an arcuate screen member to disintegrate aeration cores therebetween. The arcuate screen member is configured to discharge thatch from the single processing rotor in a generally vertical direction into engagement with a rotating fluff roll. The fluff roll is configured with a pair of opposing rigid bats affixed to a central shaft for rotation around an axis of rotation. A plurality of extruded flexible plastic cords extend from the rigid bats into the direction of rotation of the fluff roll to engage the thatch portions discharged from the processing rotor and urge the thatch portions rearwardly into a collection hopper. The flexible plastic cords yield to any earthen pieces of aeration cores that might be discharged from the processing rotor to permit the discharged earthen pieces to be recycled back toward the processing rotor. The processing rotor can be driven in opposing directions to enable the core destroying machine to be operated in a core collection mode. The fluff roll is operable to direct the intact aeration cores passing over the top of the processing rotor rearwardly into the collection hopp…
