摘要： An agricultural implement system is provided including a fluid conduit configured to provide product to a ground engaging tool. The ground engaging tool is configured to deposit the product into soil. The agricultural implement system also includes an air source fluidly coupled to the fluid conduit, and configured to provide an air flow through the fluid conduit in a downstream direction toward the ground engaging tool. The agricultural implement system further includes a product delivery system fluidly coupled to the fluid conduit, and configured to transfer the product into the air flow. In addition, the agricultural implement system includes a product flow measurement system configured to determine a mass flow rate of the product based on a pressure drop between an upstream portion of the fluid conduit and a downstream portion of the fluid conduit, a flow rate of the air flow, and a velocity of the air flow.

摘要： A product distribution control system for an agricultural system includes a controller having a memory and a processor. The controller is configured to receive a first signal indicative of a prescription map. The controller is further configured to determine a first parameter associated with operation of an air cart of the agricultural system based at least in part on the prescription map. The controller is further configured to determine at least one of a second parameter associated with operation of a work vehicle of the agricultural system based at least in part on the prescription map, and a third parameter associated with an implement of the agricultural system based at least in part on the prescription map, wherein the implement includes one or more row units. The controller is further configured to output, in response to determining the first parameter, a second signal indicative of an instruction to control a first element of the air cart based at least in part on the first parameter, output, in response to determining the second parameter, a third signal indicative of an instruction to control a second element of the work vehicle based at least in part on the second parameter, and output, in response to determining the third parameter, a fourth signal indicative of an instruction to control a third element of the implement based at least in part on the third parameter.

摘要： An agricultural metering system includes a meter roller having multiple flutes and recesses, in which the meter roller is configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The agricultural metering system also includes a shaft configured to drive the meter roller to rotate, and a clutch assembly operatively coupled to the meter roller. The clutch assembly includes a magnetorheological (MR) fluid, a rotation rate of the meter roller is at least partially dependent on an effective viscosity of the MR fluid, and the effective viscosity of the MR fluid is controllable based at least in part on an effective magnitude of a magnetic field applied to the MR fluid.
