Abstract: Apparatus, systems and methods are provided for monitoring yield while harvesting grain. Grain released from paddles on the clean grain elevator chain of a harvester contacts a flow sensor which reports the rate of grain flow through the clean grain elevator. In some embodiments a brush is mounted to the chain and disposed to clean the flow sensor surface. In other embodiments a bucket mounted to the clean grain elevator chain releases grain against the flow sensor at a rate dependent on a grain property.

Abstract: Systems, apparatuses, and methods for agricultural monitoring of soil characteristics and determining soil color are described herein. In one example, a method of calculating soil color data includes obtaining, with sensors of a soil apparatus, soil measurements. The method further includes calculating soil color values in a visible spectrum including at least one of red, green, and blue color values based on the soil measurements and determining color data for at least one color image without false image artifacts based on the calculated soil color values and associated coordinates within an agricultural field.

Abstract: Systems, methods and apparatus for imaging and characterizing a soil surface and a trench in the soil surface formed by an agricultural implement. The sensors are disposed on the agricultural implement in data communication with a processor to generate the soil surface and trench images which may be displayed to the operator. In one embodiment, the sensors include one or more time of flight cameras for determining a depth of the trench and other characteristics of the surrounding soil surface and the trench, including detection of seeds, soil or other debris in the trench and moisture lines within the trench. The system may control operating parameters of the implement based on the generated images.

Abstract: Disclosed are devices, systems and methods related to agricultural planters. In some implementations, the row unit includes a soil engaging member, where the soil engaging member engages at least one sidewall of a trench and displaces soil from the sidewall to cover the seed. In further implementations, the row unit includes a sensing system for sensing sidewall compaction and/or soil moisture.

Abstract: A sensor assembly for determining yield of grain harvested by a harvesting machine during harvesting operations. The sensor assembly includes a sensor housing, a displaceable sensor member and a displacement sensor. The sensor housing is mounted to the grain elevator housing above an upper sprocket of a conveyor disposed within the grain elevator housing. The sensor member is displaceably supported via the sensor housing within the elevator housing above the upper sprocket and along a direction of travel of the grain piles thrown by the conveyor flights rotating around the upper sprocket. The thrown grain piles produce a grain force on the sensor member causing a displacement of the sensor member in relation to the grain force. The displacement sensor generates a grain force signal corresponding to the displacement of the sensor member.

Abstract: A method of determining a mass flow rate, volumetric flow and test weight of grain during harvesting operations. A sensor is disposed in the harvesting machine against which clean grain piles are thrown by the clean grain elevator flights. The sensor changes the direction of the clean grain pile such that each clean grain pile compresses into a substantially discrete, contiguous shape producing discrete grain forces resulting in discrete signal pulse magnitudes generated by the sensor. The mass flow rate is calculated by summing the signal magnitudes and dividing the summed magnitudes by the sampling period. The volumetric flow rate is calculated by multiplying the pulse width generated by the sensor by a multiplier which relates pulse width to volumetric flow. The test weight of the clean grain is calculated by dividing the mass flow rate by the volumetric flow rate.
