Rapid Cleanout Mixing Drum with Multiple Functional Zones

摘要

A horizontal rotating drum for mixing and drying treated seed with multiple functional zones separated by one or more dams that are attached to and rotate with the drum. The dam regulates the flow of seed through the drum's functional zones. The dam has one or more cleanout passages and an overflow passage centrally disposed within the dam to selectively regulate seed flow.

主权项

1. A horizontal mixing drum for mixing and drying seed comprising:
a. a drum that is elongated and hollow with an inlet end and a discharge end, where the drum is rotated about a central longitudinal axis; b. an inlet aperture in the inlet end for receiving seed that accumulates in the interior of the drum thereby forming an aggregate; c. a dam attached to the interior of the drum that rotates with the drum, the dam has:
i. at least one peripheral aperture defining a cleanout passage disposed adjacent to the interior of the drum;ii. a central aperture defining an overflow passage;iii. a retaining portion positioned between the cleanout passage and the overflow passage; and d. whereby the dam selectively limits the progression of the aggregate toward the discharge end such that:
i. the portion of the aggregate that is shorter than the peripheral aperture will progress through the cleanout passage;ii. the portion of the aggregate that accumulates to the height of the central aperture will progress through the overflow passage;iii. the remaining portion of the aggregate is retained.
