Abstract: A batch-type particulate treating apparatus (10) includes an upright bin or hopper (20) equipped with a central, rotatable lifting augur (68) having a bored shaft (70) and helical flighting (80, 82). Coating liquid passes through the bore (72) of shaft (70), and is delivered through ejectors (86, 88) mounted on the augur flighting (80, 82). A pneumatic assembly (16) serves to direct pressurized air upwardly through a clearance (96) between the augur base and the adjacent inner surfaces of hopper (20). In operation, liquid coating material is ejected into the particulates during rotation of the augur (68) and operation of the pneumatic assembly (16), in order to uniformly and efficiently coat the particulates. The apparatus (10) is particularly designed for treating of seeds.

Abstract: An improved seed metering wheel assembly is provided to deliver a substantially constant flow of seed to a downstream treating device or the like, without any substantial surging of seeds. The seed metering wheel assembly includes an axially rotatable metering wheel having a plurality of strategically sized and arranged seed metering openings therethrough, arranged in circular arrays of differently sized metering openings. In another embodiment, the seed metering wheel includes a central hub section and an outermost rib, with a series of ribs between the hub section and rim, which lie along respective non-diameter chords. Incoming seed is delivered from a seed hopper outlet by gravitation to the metering wheel, which preferably provides a substantially constant open area while preventing wholly unobstructed flow of seeds.

Abstract: A particulate material treating system (458) includes a loss-in-weight particulate material bin assembly (460), a particulate material metering device (462), and a downstream treater (464) yielding a treated material output (468). A controller (470) is employed to determine the flow rates of material from the bin assembly (460) using loss-in-weight calculations, and this information is used to at least in part control the operation of the metering device (462).

Abstract: A tillage coulter unit (22, 122) adapted for use with a farm implement (10) is provided which permits high speed tillage operations (e.g., field fertilization using liquid fertilizer such as ammonia, or seeding) without undue soil disruption or fertilizer vaporization.

Abstract: A low-profile particulate handling assembly is provided for use in conjunction with a downstream treating device, such as a seed treater unit. The assembly includes a plurality of juxtaposed particulate bins and a surmounting turret assembly designed to successively deliver particulates to the bins. The particulates within the bins are delivered to the downstream treating device through respective lower outlets each equipped with an adjustable slide gate assembly and a lower, multiple-chute assembly. Preferably, each bin has a top wall which in plan configuration approximates a sector of a circle, planar sidewalls, and downwardly tapered, arcuate sidewall structure leading to the lower outlet; in this fashion, the bins can be grouped with the sidewalls in close adjacency, and with the outlets located to feed into a single inlet of the downstream treating device.
