Description
MODULAR HOPPER CONE
This disclosure relates to the field of storage bins for particulate material such as grain, fertilizer, and the like, and in particular an system for providing a modular hopper cone for .. storage bins that can be transported in sections and then bolted together.
BACKGROUND
Bins for storage of particulates commonly include a cone shaped hopper floor so that the particulates flow downward to an opening at the bottom of the cone to empty the bin. These hopper cones are commonly manufactured and welded as a single unit and then transported to a storage site where the bin is then installed on the hopper cone. Road traffic regulations vary between jurisdictions but in most cases there is a limit to the width of the hopper cones that can be transported on roads. Transporting loads in excess of the legal width can require warning vehicles behind or ahead of the transport vehicle, permits, and non-direct routes to avoid obstructions that significantly increasing transport costs.
To avoid this costly transport, hopper cones have been developed that are shipped in smaller parts and then assembled at the storage site by bolting the parts together. These bolted cones include legs attached to a support band and then small steel pieces that are in turn bolted to the band in rows Such bolt together cones are made for example by Darmani Grain Storage Systems of Fiske, Saskatchewan, Canada and by Bridgeview Manufacturing Inc. of Gerald, Saskatchewan, Canada. The legs and supporting band structure are bolted together and the hopper cone is then assembled from sheets of steel (60-80 or more sheets depending on the cone diameter) that are bolted together by one person inside the hopper inserting the bolts and another person outside attaching the nuts.
