Abstract
A system for controlling air flow within an agricultural product metering system is provided. One system for distributing an agricultural product includes an air conveyance system having a blower configured to provide an air stream for moving metered product toward a distribution device. The air conveyance system is mounted on an air cart. The system also includes control circuitry mounted on an agricultural vehicle, and configured to adjust a speed of the blower based at least partially on a product flow rate from the air cart.
Claims19
A system for distributing an agricultural product, comprising:
- an air conveyance system having a blower configured to provide an air stream for moving metered product toward a distribution device, wherein the air conveyance system is mounted on an air cart;
- and
- control circuitry mounted on an agricultural vehicle, and configured to adjust a speed of the blower based at least partially on a signal indicative of a product flow rate from the air cart;
- wherein the blower comprises a hydraulically controlled fan, and the control circuitry is configured to adjust the speed of the hydraulically controlled fan via a flow control device mounted on the agricultural vehicle.
An agricultural vehicle system comprising:
- a hydraulics controller mounted on an agricultural vehicle, wherein the hydraulics controller is configured to receive a signal indicative of a product flow rate from an air cart, and to determine a desired fan motor speed based at least partially on the signal;
- and
- a flow control device mounted on the agricultural vehicle, wherein the flow control device is communicatively coupled to the hydraulics controller, and configured to control a flow of hydraulic fluid to a fan motor on the air cart based on the desired fan motor speed.
A system for distributing an agricultural product, comprising:
- a hydraulics controller configured to receive a first signal indicative of a ground speed of an air cart, and a second signal indicative of a desired product flow rate, wherein the hydraulics controller is configured to determine a desired fan motor speed based at least partially on the first signal, and the second signal;
- a fan motor mounted on the air cart, and configured to provide an air stream for moving metered product toward a distribution device;
- and
- a flow control device communicatively coupled to the hydraulics controller, wherein the flow control device is configured to control a flow of hydraulic fluid to the fan motor based on the desired fan motor speed, wherein the flow control device is mounted on an agricultural vehicle configured to tow the air cart.
