Abstract
An air cart for use in an agricultural air seeding system includes at least one tank for holding a material, and a metering system associated with the at least one tank. The metering system is configured for metering the material from the at least one tank at an output rate. A sensor senses a parameter associated with an angular orientation of the air cart relative to a reference plane, and provides an output signal indicative of the angular orientation. An actuator adjusts an output rate of the metering system. A controller is coupled with each of the actuator and the sensor and receives the output signal from the sensor. The controller is configured for controlling the actuator and thereby adjusting the output rate of the metering system, dependent upon the output signal.
Claims28
An air cart for use in an agricultural air seeding system, comprising:
- at least one tank for holding a material;
- a metering system associated with said at least one tank, said metering system being configured for metering said material from said at least one tank at an output rate;
- a sensor for sensing a parameter associated with an angular orientation of said air cart relative to a reference plane, said sensor providing an output signal indicative of said angular orientation;
- an actuator for adjusting said output rate of said metering system;
- and
- a controller coupled with each of said actuator and said sensor and receiving said output signal from said sensor, said controller being configured for controlling said actuator and thereby adjusting said output rate of said metering system, dependent upon said output signal.
A metering control system for use in an agricultural air cart, comprising:
- a sensor for sensing a parameter associated with an angular orientation of the air cart relative to a reference plane, said sensor providing an output signal indicative of said angular orientation;
- an actuator for adjusting an output rate of a metering system;
- and
- a controller coupled with each of said actuator and said sensor and receiving said output signal from said sensor, said controller being configured for controlling said actuator and thereby adjusting the output rate of the metering system, dependent upon said output signal.
A method of controlling an output rate of a metering system for a granular material in an agricultural air cart, said method comprising the steps of:
- sensing a parameter associated with an angular orientation of the air cart relative to a reference plane;
- and
- controlling an actuator to adjusting an output rate of the metering system, dependent upon said sensed parameter.
