Centrifugal lifter-spreader with adjustable swivel spreader disc - has swivel axis set above disc for accurate dosing

摘要

Seen in plan view in relation to the travel direction (33) the swivel axis (32) is set behind the drive shaft (34) of the spreader disc, with the shaft in the upright position. The disc drive block (14) can swivel back with the disc (15). A setting device (20) is pref mounted between the drive block (14) and the spreader frame (2). The setting device can have remote-control preferably using a servomotor (20). The drive block can be pushed and pulled against the setting device by an elastic element (21) allowing obstructions to be overcome. ADVANTAGE - The larger swivel range allows good access to the spreader discs when the discs are swivelled backwards.
