Centrifugal type fertilizer distributor has axially extending groove portions that are arranged at switching groove, so as to determine operating area of throwing vanes associated with actuator

摘要

The fertilizer distributor connects the partial areas of throwing vanes (7,8) and/or adjustable vanes associated with an actuator. A portion of an adjusting shaft of the actuator is set with respect to the hollow shaft cooperating with the actuating element cooperation portion. A switching element is arranged in adjusting shaft or hollow shaft corresponding to a helically extending switching groove engaged with driving element. The axially extending groove portions are arranged at switching groove, such that the operating area of throwing vanes is determined.
