Metering assembly for an air seeder
First Claim
1. A metering assembly for use with an air seeding system for delivering one or more particulate materials to an air seeding apparatus, the air seeding system comprising a product tank, configured to hold a particulate material and having an outlet, the metering assembly comprising:
- at least one metering device, each metering device having;
a housing,an inlet positioned in the housing to receive particulate material from the outlet of the product tank,a first loading zone and a second loading zone, anda rotatable flow controller provided at or near the inlet and operative to route particulate material that has entered the metering device through the inlet to either the first loading zone or the second loading zone, whereby when the flow controller is rotating in a first direction, particulate material is routed only to the first loading zone and when the flow controller is rotating in a second direction, particulate material is routed only to the second loading zone;
a first air stream passage in communication with the first loading zone so that when particulate material is routed to the first loading zone, the particulate material enters the first air stream passage which then feeds the particulate material to a first soil engaging member; and
a second air stream passage in communication with the second loading zone so that when particulate material is routed to the second loading zone, the particulate material enters the second air stream passage which then feeds the particulate material to a second soil engaging member.

Abstract
A metering assembly is provided for use with an air seeding system for delivering one or more particulate materials to an air seeding apparatus, the air seeding system comprising a product tank, configured to hold a particulate material and having an outlet, the metering assembly comprising at least one metering device, the metering device having a housing, an inlet positioned in the housing to receive particulate material from the outlet of the product tank, a first loading zone and a second loading zone, and a flow controller provided beneath the inlet and operative to route particulate material that has entered the metering device through the inlet in a first direction towards the first loading zone and in a second direction towards the second loading zone.

25. A method for seeding a portion of land with one or more particulate materials using an air seeding apparatus having a metering assembly for metering out the one or more particulate material, the metering assembly comprising at least one metering device for receiving the one or more particulate material having a first loading zone and a second loading zone, comprising:
-
providing a rotatable flow controller in the at least one metering device operative for routing the at least one particulate material into either the first loading zone or the second loading zone; rotating the rotatable flow controller in a first direction when it is desirable to route the at least one particulate material into the first loading zone; rotating the rotatable flow controller in a second direction when it is desirable to route the at least one particulate material into the second loading zone; and preventing the rotatable flow controller from rotating in either the first or second direction when it is desirable to prevent the flow of particulate material into either the first loading zone or the second loading zone.
