Run selection mechanism
A run selection mechanism is provided for selectively directing the flow of particulate material from an air cart. The mechanism includes a chute for receiving metered particulate material. The chute has an output. A first primary conduit has an output communicating with a first pneumatic primary run and a second primary conduit has an output communicating with a second pneumatic primary run. A selector selectively directs the metered particulate material to one of the output of the chute, the first pneumatic primary run and the second pneumatic primary run.
1. A run selection mechanism for selectively directing the flow of particulate material from an air cart, comprising:
a particulate meter for selectively metering the particulate material;
a chute for receiving the metered particulate, the chute having an input and an output;
a first primary conduit having an input communicating with the chute and an output communicating with a first pneumatic primary run;
a second primary conduit having an input communicating with the chute and an output communicating with a second pneumatic primary run; and
a selector which includes first and second rotatable members, the first and second rotatable members including passageways therethrough, the passageways partially defining the chute, the selector movable between:
a calibration position wherein the particulate material flows from the particulate meter to the output of the chute;
a first primary position wherein the particulate material flows from the particulate meter to the output of the first primary conduit; and
a second primary position wherein the particulate material flows from the particulate meter to the output of the second primary conduit.
2. The run selection mechanism of claim 1 further comprising a meter module for housing the particulate meter, the meter module including an input for receiving the particulate material from the air cart, a particulate output for directing particulate from the particulate meter to the input of the chute, and a meter cleaning output.
3. The run selection mechanism of claim 1 wherein the selector is further movable to cleanout position wherein the meter cleaning output communicates with the chute.
4. The run selection mechanism of claim 3 wherein the meter cleaning output is isolated from the chute with the selector in the calibration position.
5. The run selection mechanism of claim 1 wherein the selector includes pivotable first and second gates, the first gate isolating the first primary conduit from the chute and the second gate isolating the second primary conduit from the chute with the selector in the calibration position.
6. The run selection mechanism of claim 1 wherein the selector includes a pivotable first gate, the first gate isolating the output of the chute from the input of the chute with the selector in the first primary position.
7. The run selection mechanism of claim 1 wherein the selector includes pivotable first and second gates, the first gate isolating the first primary conduit from the chute and the second gate isolating the output of the chute from the input of the chute with the selector in the second primary position.
