Abstract
A vibratory conveyor for particles of tobacco or other bulk material has a trough with an elongated bottom wall the upper side of which merges smoothly into a downwardly sloping convex cylindrical or substantially cylindrical external surface of a tubular or like member forming part of the front portion of the trough. This ensures that fragments of dust (if any) which are being entrained by the particles of bulk material are less likely to be expelled or permitted to escape from successive increments of the flow of bulk material advancing beyond the bottom wall of the trough. Moreover, the particles of conveyed bulk material are more likely to remain in their prescribed path.
Claims10
A vibratory conveyor for the transport of particles of bulk material in a predetermined direction, comprising a trough having a vibratory first bottom wall;
- a particle receiving first portion and a particle discharging second portion spaced apart from said first portion in said direction, said first bottom wall extending in said direction between said first and second portions, each of said first and second portions having a boundary extending transversely of said direction and at least one of said boundaries having an aerodynamically rounded profile, said profile being defined by an external surface of a member carried by and vibrating with said first bottom wall and forming part of one of said first and second portions;
- a vibratory second bottom wall spaced apart from and disposed beneath and inclined relative to said first bottom wall in said direction from one of said first and second portions toward the other of said first and second portions;
- and skirts flanking said second bottom wall.
A vibratory conveyor for the transport of particles of bulk material in a predetermined direction, comprising a trough having a vibratory bottom wall, a particle receiving first portion and a particle discharging second portion spaced apart from said first portion in said direction, said bottom wall extending in said direction from said first portion toward said second portion and said first portion including a tubular rear wall carried by said bottom wall, each of said first and second portions having a boundary extending transversely of said direction and at least one of said boundaries having an aerodynamically rounded profile, said profile being defined by an external surface of a member carried by and vibrating with said bottom wall and forming part of one of said first and second portions.
A vibratory conveyor for the transport of particles of bulk material in a predetermined direction, comprising a trough having a vibratory bottom wall, a particle receiving first portion and a particle discharging second portion spaced apart from said first portion in said direction, said bottom wall extending in said direction from said first portion toward said second portion, said first portion including a partly tubular member extending transversely of said direction and having a concave side confronting said second portion, each of said first and second portions having a boundary extending transversely of said direction and at least one of said boundaries having an aerodynamically rounded profile, said profile being defined by an external surface of a member carried by and vibrating with said bottom wall and forming part of one of said first and second portions.
A vibratory conveyor for the transport of particles of bulk material in a predetermined direction, comprising a first trough having a vibratory bottom wall, a particle receiving first portion and a particle discharging second portion spaced apart from said first portion in said direction, each of said first and second portions having a boundary extending transversely of said direction and at least one of said boundaries having an aerodynamically rounded profile, said profile being defined by an external surface of a member carried by and vibrating with said bottom wall and forming part of one of said first and second portions, said bottom wall being elongated and extending from said first portion toward said second portion;
- and a second trough disposed at a level above said first trough and having a particle receiving first portion and a particle discharging second portion at least partially overlying said bottom wall, at least said second portion of said second trough having a boundary with an aerodynamically rounded profile.
