These fabricated steel boxes are designed for storage of small lot bulk seed products. Boxes can be stacked using optional steel covers, and have formed upper flanges to eliminate sharp edges common to many other box designs. Solid floors are standard equipment, however, partial perforated floors for aeration can be provided as an option. Boxes can be unloaded using a box dumper or commercial tilt head forklift. Hopper bottom pallet boxes can also be provided on a custom basis.
Rectangular spouting is generally used to eliminate extra transitions between rectangular valves and equipment inlets. This frequently reduces the height required to obtain a given flow rate. Standard sizes range from 6″ to 12″ square, however, other sizes can be easily fabricated on a custom basis. Rectangular transitions are also available, including elbows, square to round fittings, cushion boxes, and flange adapters.
Outlet gates are used to shut off product flow from holding bins or charge hoppers using a sliding plate. Standard gates have steel wear surfaces for low headroom installations. Rack & pinion gates are extended to remove the rack from the product area, reducing potential for seed leakage.
These units help solve problems during field installation of commercial magnets in existing round spouting. Prefabricated units are available for 4″, 6″, and 8″ diameter spouting, with other sizes and rectangular flanges bid on request.
Letdown ladders reduce seed damage due to long vertical drops, either inside holding bins or in transfer spouting. Open ladders permit product to flow from the lowest exposed cup as the bin fills. Enclosed ladders are designed to replace vertical spout sections. A modified version is also available for inclined locations, and features a replaceable wear liner on the lower surface. Ladder cups are generally lined with 1/8″ gum rubber, but can be supplied unlined for low volume or treated seed applications. Optional prefabricated inlet and outlet fittings are available for many applications.
Cob bins provide temporary storage of non-free flowing products such as corn cobs, and utilize oversize gates to minimize bridging during product discharge. Clam gate designs are more common, however, modular slide gate designs are also available for larger installations. Hydraulic pump units are generally located away from the door, with either manual or electrically operated control valves.
