DEVICE FOR DISTRIBUTING BULK MATERIAL WITH A DISTRIBUTION SPOUT SUPPORTED BY A CARDAN SUSPENSION

摘要

A distribution device (100) for distributing bulk material with a distribution spout (102) on a cardan suspension (110) that has a first and a second gimbal member (112, 114) pivotable about two perpendicular suspension axes (A, B). A drive arrangement has a first and a second transmission mechanism (122, 124) for controlling pivotal motion of the distribution spout (102) about the suspension axes. In accordance with the invention, the drive arrangement has a further cardan joint (130), with a first part (132) pivotable about a third axis (C) and a second part (134) pivotable about a fourth axis (D), and a rotary motor (142) for driving a rotary drive shaft (140) that is connected to the cardan joint (130) by means of an articulated connecting arm (144). The rotational position and the axial position of the drive shaft (140) determine the pivotal position of the second part (134) about the third and fourth axes (C, D) respectively. The transmission mechanisms (122, 24) transmit torque about the third and fourth axes (C, D) from the cardan joint (130) to the cardan suspension (110) for pivoting the distribution spout (102) about 1 the firstand second axes (A, B) respectively.
