Abstract:
Embodiments of systems and approaches for managing post-harvest crop quality and pests are described. Such a system may include a plurality of edge devices each comprising sensor components and collectively forming a mesh network, for measuring the local physical environment within stored crops and, for example, transmitting the measurements to a service from within the crop storage area. In certain embodiments, such a system may be used to manage post-harvest crops and storage areas-for example, approaches are described for determining fumigation treatment duration, determining phosphine dosage, determining heat treatment duration, and determining safe storage time for crops.
Abstract:
Combine harvesters are provided for use in harvesting seed corn from corn plants in fields. In connection therewith, a method for producing such seed corn from the corn plants, for use in growing subsequent corn plants, includes measuring a moisture content of corn kernels on ears of the corn plants in the field and removing, by one of the combine harvesters, the ears of corn from the corn plants when the moisture content satisfies a threshold moisture content. The method then includes separating the corn kernels from cobs of the ears of corn onboard the combine harvester and collecting the separated corn kernels for use as seed corn, whereby one or more subsequent corn plants can be grown from the collected corn kernels.
Abstract:
An air conditioning system and methods of use regulate a moisture content of an agricultural product in a grain bin. The system receives headspace air from the headspace of the grain bin, which generally has a higher moisture content than ambient air. The system further receives ambient air and mixes the headspace air and the ambient air into a ratio comprising a target moisture content. The air mixture is provided into a grain bin plenum, where it then permeates through to agricultural product, thereby regulating the moisture. The system and method can be used to bring the agricultural product to a target moisture content that is preferred when storing the agricultural product.
Abstract:
There is a grain aeration system for a grain bin. The system includes a gas entry duct configured to receive gas and a gas distribution pipe extending upwardly from the gas entry duct and having a height. The gas entry duct extends along a base of the grain bin. The gas distribution pipe includes a permeable section and an impermeable section. The permeable section includes a plurality of perforations. The permeable section is above the impermeable section. There is also a grain bin, having a surrounding wall and roof. There is a gas entry duct extending from outside the surrounding wall to inside the surrounding wall and a gas distribution pipe extending upward from the gas entry duct. The gas distribution pipe has a permeable section above an impermeable section.
Abstract:
A grain aeration system facilitates thorough and efficient aeration of grain within a grain bin. The system includes a grain bin having a top vent and a bottom vent. A stand is positioned within the grain bin. A duct includes a loop section supported on the stand and an extension extending from the loop section out through the bottom vent in the grain bin. The duct has a duct wall and a plurality of perforations extending through the duct wall. A blower drives air flow out of the bottom vent creating air flow into the grain bin through the top vent and into the duct wherein the blower is configured to aerate grain positioned within the grain bin.
Abstract:
A control system for controlling a shared variable frequency drive for operating more than one mechanical systems of a grain bin. The control system includes at least one processor circuit that is configured to operate the shared VFD in both a first mode, wherein operating in the first mode results in operating a fan assembly of the grain bin, and a second mode, wherein operating in the second mode results in operating an unload sweep assembly within the grain bin.
Abstract:
A system for controlling the aeration of a grain bin storage device. The system comprises a grain bin storage device, a ventilation fan, a variable fan drive motor, and a controller configured to receive user input and grain bin storage device parameters. The system controls operation of the ventilation fan at various speeds to maintain a desired volumetric flow rate per bushel of grain. The controller monitors the static pressure within the grain bin storage device and adjusts the speed of the ventilation fan based on an optimal static pressure derived from the user input and grain bin storage device parameters.
Abstract:
A modeling framework for evaluating the impact of weather conditions on farming and harvest operations applies real-time, field-level weather data and forecasts of meteorological and climatological conditions together with user-provided and/or observed feedback of a present state of a harvest-related condition to agronomic models and to generate a plurality of harvest advisory outputs for precision agriculture. A harvest advisory model simulates and predicts the impacts of this weather information and user-provided and/or observed feedback in one or more physical, empirical, or artificial intelligence models of precision agriculture to analyze crops, plants, soils, and resulting agricultural commodities, and provides harvest advisory outputs to a diagnostic support tool for users to enhance farming and harvest decision-making, whether by providing pre-, post-, or in situ-harvest operations and crop analyses.
Abstract:
A stir alarm device for monitoring a forced air in-bin grain stirring system and alerting an individual when the stirring system malfunctions. The stir alarm device may include a movement device which is movably secured to the stirring system, such that movement of the stirring system causes movement of the movement device. The stir alarm device may further include a detection mechanism for monitoring the movement of the movement device. The stir alarm may also include a signaling device operably attached to the detection mechanism, the signaling device for signaling a malfunction when an amount of movement detected by the movement detection mechanism is below a threshold for a predetermined period of time and may include methods or components to control the operation of the stir machine and/or drying system.
Abstract:
The invention relates to a V-shaped trough comprising two vertical side walls joined by two converging top walls, said walls being provided with a plurality of openings, thereby making the grain columns between the rows of troughs smaller inside the tower and increasing the sped of drying, since the thickness of the grain columns is reduced, thus shortening the drying time.
