Alignment system for a blocking member of a planting unit

An alignment system for fixing the relative position of a seed meter with respect to a delivery system at a hand-off location where seed traveling in a first direction of movement of the seed meter transitions to a second direction of movement of the delivery system, the alignment system comprising:

• a delivery system housing at least in part surrounding a moving pickup member of the delivery system, the pickup member moving the seed in the second direction;
• a transition member mounted to at least one of the seed meter and the delivery system housing, the transition member defining a transition recess receiving the pickup member of the delivery system as the pickup member moves in the second direction;
• an interlocking arrangement having at least one alignment projection extending from at least one of the transition member and the delivery system housing, and a complementary at least one alignment recess formed in the other of the at least one of the transition member and the delivery system housing, the at least one alignment projection and alignment recess in interlocking engagement with each other, wherein the engagement of the at least one alignment projection with the at least one alignment recess positions the transition member in alignment with the first direction and positions the transition recess in alignment with the second direction;
• another interlocking arrangement having at least one other alignment recess formed in at least one of the delivery system housing and the seed meter, and a complementary at least one other alignment projection extending from the other of the at least one of the delivery system housing and the seed meter, the at least one other alignment projection and other alignment recess being configured for interlocking engagement with each other;
• and
• an outer recess extending into the other alignment projection from a side of the other alignment projection that is removed from an interface between the other alignment projection and the other alignment recess, the outer recess configured to receive a latch to secure the delivery system housing to the seed meter.

• an interlocking arrangement having at least one alignment projection extending from at least one of the transition member and the delivery system housing, and a complementary at least one alignment recess formed in the other of the at least one of the transition member and the delivery system housing, the at least one alignment projection and alignment recess being in interlocking engagement with each other, wherein the engagement of the at least one alignment projection with the at least one alignment recess positions the transition member in alignment with the first direction and positions the transition recess in alignment with the second direction;
• wherein the seed meter includes at least one tapered recess;
• wherein the transition member includes at least one side extension, a first side of the at least one side extension providing a face along which the seed is moved in the first direction by the seed meter, and a second side of the at least one side extension providing a tapered geometry extending away from the first side of the at least one side extension;
• wherein the at least one tapered recess and the tapered geometry are configured for interlocking engagement with each other;
• and
• wherein the engagement of the at least one tapered recess with the tapered geometry positions the transition member in alignment with the first direction and positions the transition recess in alignment with the second direction.
