Abstract

Official abstract text for this publication.

A planting implement including a toolbar and a seed metering system supported by the toolbar. The seed metering system includes at least one row unit. Each row unit includes a frame, an auxiliary seed hopper supported by the frame, a seed meter fluidly coupled to the auxiliary seed hopper, and a vacuum fan fluidly coupled to the auxiliary seed hopper and the seed meter in a closed fluid system in which the vacuum fan recirculates air through the auxiliary seed hopper and the seed meter.

First claim

Opening claim text (preview).

What is claimed is: 1. A planting implement, comprising: a toolbar; and a seed metering system supported by the toolbar and including at least one row unit, each row unit including: a frame; an auxiliary seed hopper supported by the frame; a seed meter fluidly coupled to the auxiliary seed hopper; and a vacuum fan fluidly coupled to the auxiliary seed hopper and the seed meter in a closed fluid system in which the vacuum fan recirculates air through the auxiliary seed hopper and the seed meter; wherein the auxiliary seed hopper has an air intake port and the seed meter has a vacuum port such that the vacuum fan recirculates air through the seed meter by drawing air out of the vacuum port of the seed meter and exhausting air into the air intake port of the auxiliary seed hopper; wherein each row unit further includes a vacuum sensor fluidly coupled to the vacuum port of the seed meter; wherein each row unit further includes a fan mount which mounts the vacuum fan onto the auxiliary seed hopper; wherein the auxiliary seed hopper includes a support member that fluidly connects the vacuum fan to an inside of the auxiliary seed hopper, and the fan mount is mounted onto the support member. 2. The planting implement of claim 1 , wherein the vacuum fan is mounted onto the auxiliary seed hopper. 3. The planting implement of claim 1 , wherein the fan mount additionally mounts the vacuum sensor onto the auxiliary seed hopper. 4. The planting implement of claim 1 , wherein the seed metering system further includes a control unit operably coupled to the vacuum fan and to the vacuum sensor, and the control unit is configured to control the vacuum fan. 5. The planting implement of claim 4 , wherein the at least one row unit is in the form of a plurality of row units such that each vacuum fan of each row unit of the plurality of row units is independently controlled by the control unit. 6. A seed metering system for a planting implement, comprising: at least one row unit, including: a frame; an auxiliary seed hopper supported by the frame; a seed meter fluidly coupled to the auxiliary seed hopper; and a vacuum fan fluidly coupled to the auxiliary seed hopper and the seed meter in a closed fluid system in which the vacuum fan recirculates air through the auxiliary seed hopper and the seed meter; wherein the auxiliary seed hopper has an air intake port and the seed meter has a vacuum port such that the vacuum fan recirculates air through the seed meter by drawing air out of the vacuum port of the seed meter and exhausting air into the air intake port of the auxiliary seed hopper; wherein each row unit further includes a vacuum sensor fluidly coupled to the vacuum port of the seed meter; wherein each row unit further includes a fan mount which mounts the vacuum fan onto the auxiliary seed hopper; wherein the auxiliary seed hopper includes a support member that fluidly connects the vacuum fan to an inside of the auxiliary seed hopper, and the fan mount is mounted onto the support member. 7. The seed metering system of claim 6 , wherein the vacuum fan is mounted onto the auxiliary seed hopper. 8. The seed metering system of claim 6 , wherein the fan mount additionally mounts the vacuum sensor onto the auxiliary seed hopper. 9. The seed metering system of claim 6 , wherein the seed metering system further includes a control unit operably coupled to the vacuum fan and to the vacuum sensor, and the control unit is configured to control the vacuum fan. 10. The seed metering system of claim 9 , wherein the at least one row unit is in the form of a plurality of row units such that each vacuum fan of each row unit of the plurality of row units is independently controlled by the control unit.
