Abstract
A system and method for causing a differential flow rate to exist in a downspout so as to reduce abrasion of a bottom side of said downspout and to sort dry bulk material flowing therethrough. The present invention reduces the velocity of the mass of the dry bulk material, such as corn, thus preserving grain quality and reducing the exit velocity at the lower end of the spout.
Claims10
A system for delivery of dry bulk material, the system comprising:
- a chute having a top side, a bottom side, a right side and a left side, the chute for carrying a dry bulk material;
- a liner member disposed in said chute and spanning a space near said bottom side and between said right side and said left side;
- means for retaining said liner member at a predetermined location;
- where said liner member is a plate;
- a plurality of chutes and a plurality of liner members disposed in said plurality of chutes;
- wherein a connection between adjacent chutes in said plurality of chutes is made without a benefit of a chute terminal end butting flange on each of said adjacent chutes for coupling said adjacent chutes;
- and
- wherein one of said plurality of liner members spans and provides a fixed connection between adjacent chutes.
A system for delivery of dry bulk material, the system comprising:
- a plurality of chutes and a plurality of liner members disposed in said plurality of chutes;
- a first chute of said plurality of chutes having a top side, a bottom side, a right side and a left side, the first chute for carrying a dry bulk material;
- a first liner member of said plurality of liner members disposed in said first chute and spanning a space near said bottom side and between said right side and said left side;
- means for retaining said first liner member at a predetermined location;
- where said first liner member is a plate;
- wherein a connection between adjacent chutes in said plurality of chutes is made without a benefit of a chute terminal end butting flange on each of said adjacent chutes for coupling said adjacent chutes;
- wherein said first liner member is a plate of abrasive resistant steel;
- wherein:
- each of said plurality of liner members comprise a partially laminated plate of 400AR abrasive resistant steel with a backer plate welded thereto;
- said means for retaining comprising a plurality of bolts;
- and
- said backer plate being configured for permitting a shaft of a bolt of said plurality of bolts to pass therethrough while prohibiting a head of bolt to pass.
A method of manufacturing a system which is configured for carrying dry bulk material, the method comprising the steps of:
- providing a first chute with a top side, a bottom side, a right side and a left side, the chute for carrying a dry bulk material;
- providing a first liner plate within said first chute along said bottom side which substantially spans from said right side to said left side;
- connecting said first liner plate to said bottom side;
- providing a second chute;
- and
- coupling said second chute to said first chute without the use of flanges on said first chute and said second chute, and by coupling said second chute to a portion of said first liner plate which protrudes beyond an end of said first chute.
A system for delivering dry bulk material from an elevated location comprising:
- a source of dry bulk material;
- a downspout extending downward from said source of dry bulk material;
- said downspout comprising:
- a top side;
- a bottom side;
- a first side, coupled to said top side;
- a second side coupled to said top side;
- and
- a liner plate disposed adjacent to said bottom side;
- wherein said liner plate extends beyond an end of said bottom side.
