Abstract

Abstract A structure for receiving a supply of particulate solids such as grain, silage, haylage, or the like, at the top and dividing it into substantially equal portions as the feed falls by gravity to the bottom of the structure. A system of baffles and dividers directs the material and splits it into increasingly smaller, individual portions as it slides down the inclined surfaces of the structure.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 207 words
A structure for distributing a supply of solid, particulate material into a plurality of discrete portions of predetermined relative size, said structure comprising: a. an inclined chute having a discharge end adapted to deliver a supply of feed by gravity; b. an upper distributing section having four gables with upper edges disposed in a common horizontal plane, all meeting at a single point, and a plurality of discrete surfaces sloping outwardly and downwardly from said single point, the latter being located below said discharge end and in such lateral relation thereto that a supply of particulate material delivered by gravity from said discharge end falls substantially symmetrically about said point and down each of said discrete surfaces; and c. a lower distributing section having at least one external surface disposed below and sloping outwardly and downwardly from said upper distributing section, and a plurality of divider elements extending outwardly from said external surface at selected locations thereon, each of said elements having side surfaces diverging away from one another and from the plane of said external surface from an uppermost point substantially in said plane, whereby material sliding down said external surface is divided by said elements into a plurality of discrete portions of predetermined relative proportion.
Claim 2
Dependent Claim 207 words
A structure for distributing a supply of solid, particulate material into a plurality of discrete portions of predetermined relative size, said structure comprising: a. an inclined chute having a discharge end adapted to deliver a supply of feed by gravity; b. an upper distributing section having four gables with upper edges disposed in a common horizontal plane, all meeting at a single point, and a plurality of discrete surfaces sloping outwardly and downwardly from said single point, the latter being located below said discharge end and in such lateral relation thereto that a supply of particulate material delivered by gravity from said discharge end falls substantially symmetrically about said point and down each of said discrete surfaces; and c. a lower distributing section having at least one external surface disposed below and sloping outwardly and downwardly from said upper distributing section, and a plurality of divider elements extending outwardly from said external surface at selected locations thereon, each of said elements having side surfaces diverging away from one another and from the plane of said external surface from an uppermost point substantially in said plane, whereby material sliding down said external surface is divided by said elements into a plurality of discrete portions of predetermined relative proportion.
Claim 3
Dependent Claim 21 words
The invention according to claim 1 and further including a central vertical baffle extending upwardly from one of said upper edges.
Claim 4
Dependent Claim 62 words
The invention according to claim 1 wherein at least some of said divider elements are arranged at different vertical levels on said external surface than others and in such lateral relation thereto that the elements at the lower level receive substantially symmertically at said uppermost point thereof material sliding from one of said side surfaces of an element at the higher level.
Claim 5
Dependent Claim 31 words
The invention according to claim 1 wherein said discharge end is so constructed and arranged that a continuous supply of particulate matter falls therefrom in a plurality of substantially equal streams.
Claim 6
Dependent Claim 29 words
The invention according to claim 4 and further including platform means disposed symmetrically about and below the lowermost edge of said distributing section and relatively movable with respect thereto.
Claim 7
Dependent Claim 23 words
The invention according to claim 5 wherein said platform means is movable about a vertical axis through the center of said distributing section.
