The disclosure embraces a method of and apparatus for receiving bulk particulate materials from a material supply carrier into a hopper construction in which the hopper construction includes a multicellular or multitubular arrangement providing for free flowing of the material through the cells or tubes into a hopper chamber, the tubular or cellular construction being provided with a central conically-shaped void or space defined by certain of the tubes or cells being of varying lengths whereby the angle of the conically-shaped void simulates a natural angle of repose of the particulate material so that the particulate material in the hopper chamber and in the void or space seals the tubes or cells preventing cross winds or moving air from affecting or entraining the material thereby minimizing or substantially eliminating loss of the material and contamination of the environment by the material.
Apparatus for receiving particulate material from a supply carrier having a material discharge output comprising, in combination, a material receiving hopper construction, said hopper construction including a chamber, an assemblage of a plurality of open-ended cells disposed above the chamber, the cellular assemblage being adapted for registration with the discharge outlet of the supply carrier, the open-ended cells accommodating flow of the particulate material from the discharge outlet into the chamber, the cellular assemblage having a central void defined by the lower ends of certain of the cells of varying lengths, the particulate material in the cells effecting a seal for the cells substantially preventing moving air from entraining the particulate material.
Apparatus for receiving particulate material from a supply carrier having a material discharge outlet comprising, in combination, a material receiving hopper construction, said hopper construction including a chamber, a plurality of open-ended tubes in contiguous relation disposed above the chamber, the tubes being adapted for registration with the discharge outlet of the supply carrier, the open-ended tubes accommodating flow of the particulate material from the discharge outlet into the chamber, certain of the tubes being of varying lengths, the lower ends of the tubes of varying lengths defining a central void, the particulate material in the tubes effecting a seal for the tubes preventing moving aif from entraining the particulate material.
Apparatus for receiving particulate material from a supply carrier having a material discharge outlet comprising, in combination, a material-receiving hopper construction, said hopper construction including a chamber, an assemblage of a plurality of open-ended cells disposed above the chamber, the cellular assemblage being adapted for registration with the discharge outlet of the supply carrier, the open-ended cells accommodating flow of the particulate material from the discharge outlet into the chamber, the multicellular assemblage having a generally conically-shaped void defined by the lower ends of certain of the cells of varying lengths, the particulate material in the cells effecting a seal for the cells preventing moving air from entraining the particulate material.
Apparatus for receiving particulate material from a supply carrier having a material discharge outlet comprising, in combination, a material receiving hopper construction, said hopper construction including a chamber, a plurality of open-ended cells disposed above the chamber, the open-ended cells being adapted for registration with the discharge outlet of the supply carrier, the open-ended cells accommodating flow of the particulate material from the discharge outlet into the chamber, certain of the cells being of varying lengths, the lower ends of the cells of varying lengths defining a conically-shaped void, the angle of the conically-shaped void simulating the angle of repose of the particulate material piling up in the chamber, the particulate material in the cells effecting a seal for the cells preventing moving air from entraining the particulate material.
