Abstract
In an apparatus for the metered feeding of poorly flowable materials by endless conveyor belt having an upper and lower run, the conveyor belt includes carrier plates which define pockets for conveying the material from an inlet through a compacting zone and a metering zone, to an outlet at which the metered compacted material is released from the pockets and allowed to pass out of the outlet. In the metering zone the upper and lower runs of the conveyor belt are maintained in close adjacency such that the inward ends of the plates on the upper and lower runs of the conveyor belt cooperate with each other to provide a known amount of material in the pockets on the lower run of the conveyor belt.
Claims17
An apparatus for the metered feeding of poorly flowable material, such as peat, garden mould and the like, from a delivery station to a sacking station by means of an endless conveyor belt means having an upper and lower run, said apparatus comprising
- a conveyor housing having an inlet and an outlet,
- a compaction zone having an upstream end and a downstream end, and a metering zone;
- a plurality of spaced carrier plate means disposed transversely on said conveyor belt means, each having an inwardly and an outwardly disposed edge, the inwardly disposed edges of the plate means on the upper run of said conveyor belt means being disposed opposite the inwardly disposed edges of the plate means on the lower run of the conveyor belt means, adjacent pairs of said plate means defining pockets for carrying said material;
- compacting wall means in said compaction zone, said compacting wall means being substantially spaced from said outwardly disposed edges of said conveyor plate means and progressively less spaced from said outwardly disposed edges towards said downstream end for compaction of said material in each said pocket as it progresses through said compaction zone;
- and
- stripper means disposed in said metering zone, said stripper means being associated with said oppositely faced inwardly disposed edges of said carrier plate means on the upper and lower runs of the conveyor belt means, for volumetrically restricting said material in each said pocket on the lower run of the conveyor belt means in said metering zone.
An apparatus for the metered feeding of flowable solid material from a delivery station to a sacking station by means of an endless conveyor belt means having an upper and lower run said apparatus comprising:
- a conveyor housing having an inlet and an outlet, and downstream of said inlet and upstream of said outlet a metering zone;
- a plurality of spaced carrier plate means disposed transversely on said conveyor belt means each having an inwardly and an outwardly disposed edge, the inwardly disposed edges of the plate means on the upper run of said conveyor belt means being disposed opposite the inwardly disposed edges of the plate means in the lower run of the conveyor belt means, adjacent pairs of said plates defining pockets for carrying said material;
- and
- stripping means disposed in said metering zone, said stripping means being associated with said oppositely facing inwardly disposed edges of said carrier plate means on the upper and lower runs of the conveyor belt means for volumetrically restricting said material in each said pocket in said metering zone.
