CENTRIFUGAL WORKING MEMBER FOR SPREADING BULK MATERIALS Russian patent published in 2018 - IPC A01C17/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machinery, in particular to the working members of centrifugal spreaders of mineral fertilizers and other bulk materials. Centrifugal working member comprises drive mechanism 1, V-belt variable-speed drive 3 and disk 4 with grooved blades 5 of elastic material mounted on shaft 2. To the upper edges 6 of blades 5, spring plates 7 cooperating with stops 8 located in disc 4 are attached. Stops 8 are fixed to the axially movable disk 9 of V-belt variable-speed drive 3. Fixed disk 10 is rigidly attached to shaft 2. Movable disc 9 is mounted on the hub of fixed disk 10. Disks 9 and 10 are movably interconnected in the axial direction by means of key 11. Locking ring 12 is fixed to shaft 2 with the possibility of its fixed axial displacement. Spring 13 is provided between locking ring 12 and movable disk 9. Mechanism of drive 1 is fixed to shaft 2. Variable-speed drive 3 is connected through V-belt transmission 14 with tension roller 15 with the possibility of its transverse movement.

EFFECT: invention makes it possible to improve the stabilization of the bulk material spreading width.
