METERING APPARATUSES FOR SECTIONAL CONTROL |
摘要 |
A metering apparatus for distributing an agricultural product in a field has a meterbox configured for association with a hopper for receiving agricultural product from the hopper. A rotatable metering element is disposed within a chamber in the meterbox, and the rotating metering element is configured to deliver the agricultural product at a regulated rate from the hopper through the chamber to a product distribution line. Delivery of the agricultural product to the product distribution line may be selectively stopped by a reversibly inflatable seal between the metering element and an outlet to the distribution line, a reversible seal formed by contact between the metering element and an inlet from the hopper to the chamber, or a disengagement structure for disengaging the agricultural product from the metering element while the metering element continues to rotate. |

1. A metering apparatus for distributing an agricultural product, comprising:
a meterbox configured for association with a hopper for receiving agricultural product from the hopper; a rotatable metering element disposed within a chamber in the meterbox, the rotating metering element configured to deliver the agricultural product at a regulated rate from the hopper through the chamber to a product distribution line; and, stopping means for selectively stopping delivery of the agricultural product to the product distribution line, the stopping means comprising a reversibly inflatable seal between the metering element and an outlet to the distribution line, a reversible seal formed by contact between the metering element and an inlet from the hopper to the chamber, or a disengagement structure for disengaging the agricultural product from the metering element while the metering element continues to rotate. |
