Abstract
A container or hopper with a flexible weigh container as an inner member, in which the weigh container is supported through at least one weigh cell on a frame. In order to weigh-in a material to be proportioned, a throttling device is provided at the bottom end of the weigh container. To avoid complicated distributing arrangements and assure precise dosing, the flexible weigh container extends further downwardly like a hose through the throttling device and its bottom is attached to a movable spout which in turn is displaceable in such a manner that the flexible, hose-like extension of the weigh container is carried along with it so as to selectively discharge through different outlets of the container or hopper.
Claims7
A container for receiving a bulk material, said container being mounted on a container frame through at least one weigh-cell and comprising a flexible internal member with a bottom outlet and a throttling device adjacent the bottom of the internal member to close the outlet, wherein the flexible internal member is hose-like and extends downwardly through the throttling device and is attached at its bottom to a movable spout, the spout being selectively displaceable to positions above a plurality of different outlets such that the flexible, hose-like extension of the internal member is carried with it so as to discharge through a respective one of the outlets depending on the position of the spout.
