Abstract

An air seeder assembly that has a tank for containing commodity, a meter assembly coupled to the tank and configured to selectively distribute commodity there through, a first conduit coupled to the meter assembly to direct commodity provided to the first conduit from the meter assembly to a tool assembly, a diverter that selectively diverts commodity to the first conduit, and a sensor coupled to the diverter to identify when commodity is passing thereby.

First claim

The invention claimed is:

1. An air seeder assembly, comprising;
a tank for containing commodity;
a meter assembly coupled to the tank and configured to selectively distribute commodity there through;
a first conduit coupled to the meter assembly configured to direct commodity provided to the first conduit from the meter assembly to a tool assembly;
a diverter configured to selectively divert commodity to the first conduit; and
a sensor coupled to the diverter and configured to identify when commodity is passing thereby;
wherein the diverter comprises a flapper pivotable about a flapper axis and the sensor is positioned within the flapper.

2. The air seeder assembly of claim 1 , further comprising a second conduit coupled to the meter assembly and configured to direct commodity provided to the second conduit from the meter assembly to the tool assembly.

3. The air seeder assembly of claim 2 , further wherein the diverter has a first position that directs commodity towards the first conduit and a second position that directs commodity towards the second conduit.

4. The air seeder assembly of claim 1 , further wherein the flapper comprises a non-planar surface profile on a first side and a second side.

5. The air seeder assembly of claim 1 , further wherein the sensor is positioned inside a cavity of the diverter.

6. The air seeder assembly of claim 1 , further wherein the sensor comprises at least one wire configured to communicate a sensor reading and the at least one wire exits the flapper along the flapper axis.

7. A meter assembly, comprising;
a housing defining an inlet configured to be coupled to a tank;
a metering device coupled to the housing and configured to meter flow of commodity from the inlet;
a diverter positioned at an outlet of the housing and configured to selectively distribute commodity to at least one conduit;
a sensor coupled to the diverter and configured to identify when commodity is flowing thereby;
wherein the sensor comprises a piezoelectric sensor configured to identify the impact of commodity against the diverter.

8. The meter assembly of claim 7 , further wherein the diverter comprises a flapper pivotally coupled to the housing about a flapper axis and configured to be positionable between a first position and a second position.

9. The meter assembly of claim 8 , further wherein the flapper is formed of a first side and a second side coupled to one another and the sensor is coupled between the first side and the second side.

10. The meter assembly of claim 8 , further wherein the sensor has at least one wire configured to communicate a sensor reading and the at least one wire exits the flapper along the flapper axis.

11. The meter assembly of claim 8 , further wherein the flapper has at least one non-planar surface profile configured to intermingle commodity that contacts the non-planar surface.

12. The meter assembly of claim 7 , further comprising a second sensor coupled to the diverter.

13. The meter assembly of claim 12 , further wherein the sensor is coupled to a first surface of the diverter and the second sensor is coupled to a second surface of the diverter, wherein the first surface is configured to be in a commodity flow path when the diverter is in a first position and the second surface is configured to be in the commodity flow path when the diverter is in a second position.

14. A method for identifying a blockage of commodity in a meter assembly, comprising:
providing a housing, a metering device, a diverter, at least one conduit, a sensor, and a controller;
coupling the metering device to the housing, the metering device configured to meter flow of commodity from an inlet to an outlet of the meter assembly;
positioning the diverter at the outlet of the meter assembly, the diverter configured to selectively distribute commodity to the at least one conduit; and
coupling the sensor to the diverter, the sensor configured to communicate to the controller when commodity is flowing thereby and contacting the diverter.

15. The method of claim 14 , further comprising identifying with the controller when a blockage occurs by monitoring when the metering device is moving commodity and the sensor is not identifying flowing commodity.

16. The method of claim 15 , further comprising providing an indication when the controller identifies a blockage.

17. The method of claim 16 , further wherein the indication comprises an icon displayed on a user interface.
