Collection Device for Meter Calibration of Air Seeder Tanks

A collection device for use with a seed tank of an agricultural air seeder implement supported for movement across the ground in a forward working direction, the agricultural air seeder implement including a pneumatic delivery line for delivering seed, a seed meter for metering seed from the seed tank into the pneumatic delivery line, a calibration opening in the pneumatic delivery line through which seed can be dispensed during calibration of the seed meter, and a cover member for selectively closing the calibration opening, the collection device comprising:

• a chute extending in a longitudinal direction of the chute between a first end and a second end;
• a mounting arrangement arranged to support the chute below the calibration opening of the pneumatic delivery line such that the chute slopes downwardly from the first end to the second end of the chute;
• the chute including a top opening at a top side in alignment with the calibration opening thereabove so as to receive seed discharged through the calibration opening into the chute through the top opening;
• and
• the chute including a discharge opening at the second end through which seed collected in the chute is arranged to be discharged.
