Title: Bar-type crumbling roller
Inventor: BREDSCHNEIDER BRUNO
IPC: A01B29/04
Filed: 1989-05-02
Abstract: The invention relates to a bar-type crumbling roller for implements for working the ground and combinations thereof with implements for sowing, fertilising and for crop protection. Bar-type crumbling rollers are formed from parallel bars which are fastened on the roller spindle by means of supporting discs. Bar-type crumbling rollers are exposed to high loading, in particular transverse loading by stones and to high bearing pressure if they are also used for supporting the implements. Bar-type crumbling rollers have to be lightweight and stable, show little tendency to blockage and produce good crumbling of the ground surface. A particularly transversely stable embodiment is intended to be achieved by the invention in that all the supporting discs 5 are designed as hollow discs which are arranged on the roller spindle 6 in a mirror-inverted manner, starting from the roller centre with their hollow surfaces 9 directed towards the roller bearings 8. The roller bearings 8 are accommodated in the cavity 10 of the end discs 7, as a result of which the bar-type crumbling rollers 1 can be arranged closely one beside the other. <IMAGE>
