Abstract
Abstract A device for improving the distribution of grain delivered into the top of a grain storage bin. The device is mounted inside the bin directly beneath the discharge end of the grain delivery conveyor and consists of a funnel-shaped hopper positioned above a conical-shaped distribution plate. There are no moving parts in the device. However, the distribution plate includes overlapping lower sections that are adjustable so that the angle of the plate can be varied to change the distribution pattern within the bin.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
A distribution device for granular material such as grain and the like that is to be stored in a bin having a side wall and a roof with a fill opening providing an enclosed space, said distribution device comprising a hollow upper portion having an inlet opening and a discharge opening beneath said inlet opening, said upper portion providing a flow path for grain between said inlet opening and said discharge opening, a lower portion positioned beneath the discharge opening of the upper portion and having a distribution surface that directs grain discharged from the upper portion outwardly in all directions, said lower portion including a plurality of separate sections, said sections being movable relative to each other to vary the angle of the said distribution surface thereby changing the pattern of distribution of the granular material, said distribution surface of said lower portion having an opening directly beneath the discharge opening of the upper portion, and means mounting said upper portion and said lower portion in a fixed position relative to each other with the distribution surface of the lower portion spaced from the discharge opening of the upper portion.
Claim 2
Dependent Claim
191 words
A distribution device for granular material such as grain and the like that is to be stored in a bin having a side wall and a roof with a fill opening providing an enclosed space, said distribution device comprising a hollow upper portion having an inlet opening and a discharge opening beneath said inlet opening, said upper portion providing a flow path for grain between said inlet opening and said discharge opening, a lower portion positioned beneath the discharge opening of the upper portion and having a distribution surface that directs grain discharged from the upper portion outwardly in all directions, said lower portion including a plurality of separate sections, said sections being movable relative to each other to vary the angle of the said distribution surface thereby changing the pattern of distribution of the granular material, said distribution surface of said lower portion having an opening directly beneath the discharge opening of the upper portion, and means mounting said upper portion and said lower portion in a fixed position relative to each other with the distribution surface of the lower portion spaced from the discharge opening of the upper portion.
Claim 3
Dependent Claim
39 words
The distribution device of claim 1 in which said lower portion includes a top conical-shaped section, and said plurality of separate sections are pivotally mounted on said top section with the edges of said separate sections overlapping adjacent sections.
Claim 4
Dependent Claim
31 words
The distribution device of claim 1 in which the diameter of the discharge opening of said upper portion is approximately three times the diameter of the opening in said lower portion.
Claim 5
Dependent Claim
40 words
The distribution device of claim 3 in which said lower portion includes a top conical-shaped section, and said plurality of said separate sections are pivotally mounted on said top section with the edges of said separate sections overlapping adjacent sections.
