  • Patent number: 10517206
    Abstract: A system for dispensing crop input products from multiple meters per crop row, including: a) a georeferencing module configured to receive and process georeferenced location information; b) a prescriptive control module configured to receive the processed georeferenced location information from the georeferencing module and utilize the georeferenced location information to generate specific prescriptive rate information for individual meters in the field; and, c) a meter controller module operatively connected to the prescriptive control module. The meter controller module is configured to utilize the specific prescriptive rate information to individually control multiple meters per crop row, to simultaneously dispense crop input products at specific prescriptive rates at georeferenced locations throughout the field.

  • Patent number: 10492357
    Abstract: A system for electronically pulsing agricultural product with seed. A seed transport mechanism is affixed to a seed planter row unit having a seed metering system, operating at a high speed configured to dispense seed. The seed transport mechanism is configured to provide a seed release speed at which the seed and agricultural product exit the seed transport mechanism, the seed release speed being varied in a manner proportional to the variation in the ground speed of the seed planter row unit to minimize seed tumbling to optimize accurate placement of seed and chemical granule agricultural product at varying ground speeds of the seed planter row unit. In the various embodiments, the agricultural product is directed away from moving parts after the seed leaves the seed metering system of the seed planter row unit.

  • Patent number: 10440878
    Abstract: A system for dispensing agricultural products includes: a master controller, sets of agricultural product containers, meter devices, and secondary controllers. The meter devices are operatively connected to the product containers and configured to dispense products from the containers to rows in a field wherein each of the sets of containers is associated with a respective row in the field. The secondary controllers actuate the meter devices. Each secondary controller receives command data from the master controller and controls the meter devices for dispensing in response to the command data. Agricultural product from each product container is dispensed in accordance with operator defined instructions to the master controller. The instructions are capable of being provided to the master controller during the planting allowing the dispensing of individual containers to be controlled.

  • Publication number: 20190285448
    Abstract: An electric measurement method and apparatus for detecting a mass by an electric capacity (permittivity) or a material's dielectric constant, or alternatively, electric inductance (permeability). The mass may be any phase or combination of phases. The mass may be stationary or flowing. It may comprise discrete particles such as grain, or manufactured products such as ball bearings or threaded fasteners, etc. The mass may be a flow element in a rotameter or similar flow measurement device. The sensor comprises a volume which may be completely full or only partially full of the material. The material may be discrete components or a continuum. Sensor signals may be received by existing planter monitoring systems. In some embodiments the flow sensors are positioned external to the application port. In some embodiments sensors may be utilized which are responsive to the refractive index variation of specific chemicals.

  • Patent number: 10356975
    Abstract: A method and apparatus for minimizing the volume of a liquid carrier used for delivering an agricultural product into a furrow during planting. The apparatus includes a seed tube assembly for dispensing seed. A seed firmer assembly is operatively connected to the seed tube assembly. A seed firmer application tube assembly is mounted to the seed firmer assembly. The seed firmer application tube assembly has an outlet end for dispensing a carrier containing an agricultural product. A seed firmer brush is mounted to the outlet end of the seed firmer application tube assembly. The seed firmer brush is configured to contact the carrier containing the agricultural product during the dispensing thereof and brushing the carrier containing the agricultural product onto the seed being dispensed from the seed tube assembly.
