Split Dispensing Hopper

摘要

A split hopper for dispensing granular or powdery materials has a hopper body and a lid. At least the hopper body is formed principally from a castable resin material such as polyurethane. The hopper body is formed from two hopper body sections mating at vertical faces and hinged to one another. Tooling mounts and other features such as clamping lugs can be cast directly into the hopper body sections during the casting process. The lid may be sealed to the top of the hopper body via a ring seal that may seal both radially and axially against the hopper body. A tool holder may be provided beneath the discharge opening of the hopper body for selectively engaging tooling so that the tooling does not fall out of the hopper body when the hopper body is opened.

(A) a generally frustoconical hopper body formed from first and second hopper body sections that are hinged together at one side thereof so as to be openable to expose an interior of the hopper and closable to seal the hopper interior, each of the first and second hopper body sections being formed from a cast resin material, wherein the hopper body is open at top and bottom ends thereof; (B) first and second side seals that are located at opposite sides of the hopper body and each of which seals mating surfaces of the first and second hopper body sections to one another; and (C) a lid that covers the upper opening in the hopper body and that seals against the first and second hopper body sections.
