Abstract:
1. Metering device for supplying devices with bulk materials comprising: a housing which has a first pair of opposite sides and a second pair of opposite sides; a first pair of circular connecting openings on the first pair of opposite sides, the center points of the circular connecting openings of the first pair of circular connecting openings arranged coaxially with each other, and the diameters of the circular connecting openings of the first pair of circular connecting openings being the same; a second pair of circular connecting openings on the second pair of opposites sides, the center points of the circular connecting openings of the second pair of circular connecting openings arranged coaxially with each other, and the diameters of the circular connecting openings of the second pair of circular connecting openings being the same; a cylindrical vertical feed channel connecting the circular connecting openings of the first pair of circular connecting openings into which each circular connecting opening of the first pair of circular connecting openings seamlessly open, the feed channel having an inner wall, the feed channel having a diameter the same as the diameter of the circular connecting openings of the first pair of circular connecting openings, and the feed channel having a longitudinal axis arranged coaxially with the center points of the first pair of circular connecting openings, wherein the bulk material can be fed from above seamlessly into the feed channel via a hopper having an outlet opening with the same diameter of first pair of circular connecting openings; a cylindrical lateral channel connecting the circular connecting openings of the second pair of circular connecting openings, and orthogonally penetrating the feed channel, into which each circular connecting opening of the second pair of circular connecting openings seamlessly open, the lateral channel having an inner wall, the lateral channel having a diameter the same as the diameter of the circular connecting openings of the second pair of circular connecting openings, and the lateral channel having a longitudinal axis arranged coaxially with the center points of the second pair of circular connecting openings, wherein the penetration of the lateral channel into the feed channel produces a penetration curve corresponding to the intersection of the inner wall of the lateral channel and the inner wall of the feed channel; and a drive motor unit arranged laterally on the housing via a conveyor screw which is arranged in cantilevered fashion on a sealing body, the sealing body having an outer part having a shape corresponding to the penetration curve and fitting seamlessly with the inner wall of the vertical feed channel in accordance with the penetration curve, and which absorbs axial and radial stresses of the conveyor screw with a frustoconical part arranged in the housing in the axial direction of the conveyor screw.
