ABSTRACT:
In order to improve the metering accuracy of a pipe chain conveyor it is proposed that at least one section of a pipe loop, disposed between the filling and discharge openings, is movably resiliently mounted and is supported on at least one force measuring device. The at least one section of the pipe loop supported by the at least one measuring device can be in the form of a pipe bend or a straight pipe section, and can be mounted to a remaining, stationary portion of the pipe loop in yielding manner by means of flexible intermediate elements in order to act on the force measuring device arranged at a distance therefrom.
