发明名称 Method of providing sectional control during seeding of a field using a farm implement
摘要 A seed metering assembly for a farm implement has a meter roller that can be accessed and removed in a relatively quick manner. The seed metering assembly includes a fluted meter roller that is segmented into a number of discrete fluted sections. Each fluted section has an associated flow control member that is selectively operable to impede the flow of granular material from a seed hopper to its corresponding section of the fluted meter roller.

主权项 1. A method of providing sectional control during seeding of a field using a farm implement having a hopper that holds a volume of granular material and has a discharge opening through which the granular material to exit the hopper, the method comprising: rotating a fluted metering roller as granular material passes through the discharge opening of the hopper, the fluted metering roller having a number of fluted sections formed along a length of the roller; and selectively moving at least one of a number of flow control devices to a position between the discharge opening of the hopper and the fluted metering roller, each flow control device associated with a respective fluted section of the number of fluted sections and wherein each flow control device having a curved member, being associated with a respective one of the number of fluted sections and being independently movable between a first position in which granular material is permitted to be fed from the discharge opening of the hopper to the respective one of the number of fluted sections at a flow rate and a second position in which the curved member of the flow control device is placed between the respective one of the number of fluted sections and a portion of the discharge opening of the hopper generally aligned with the respective one of the number of fluted sections to cause flow of particulate material to the respective one of the plurality of fluted sections of the metering device to be substantially blocked.
