  • Patent number: 6806429
    Abstract: A grain flow measuring system for a flow rate of grain moving along a generally vertical grain flow path. The weight of grain conveyed along the flow path is measured when the grain impinges baffle elements, thereby generating a force corresponding to the grain weight. The force is transmitted to one or more load cells.

  • Patent number: 6582516
    Abstract: The continuous batch seed coating system of this invention includes a coating unit, liquid and dry treatment metering systems, a seed metering system, and a PLC controller. The coating unit includes a substantially unitary bowl, which is rotated to cyclically rotate seed being treated. The bowl is rotated within an enclosure, then evacuated after being treated. A peristaltic pump and a hopper-auger unit provide liquid and dry seed treatment formulations to the coating unit. The automated seed metering system pre-weighs seed to be conveyed into the coating unit. The PLC controller controls the retention time in the coating unit, the amounts and timing of seed treatment formulations, conveys seed to the coating unit, and optionally sounds alarms when one of the treatment formulations is not available or when seed is not present in the seed metering system.

  • Patent number: 6472615
    Abstract: A grain flow measuring system for a flow rate of grain moving along a grain flow path. The grain flow measuring system includes a frame, a load cell, a flow conditioning portion, and a flow measuring portion. The frame is mounted with respect to the grain flow path. The load cell is mounted to the frame. The flow conditioning portion is attached to the frame. The flow conditioning portion has a first baffle located along the grain flow path. The flow measuring portion has a second baffle and a third baffle that are located in series along the grain flow path. The second baffle and the third baffle deflect grain moving along the grain flow path and thereby causes the flow measuring portion to engage the load cell.
