Abstract

An agricultural metering system includes a releasable bearing coupler configured to selectively couple a meter roller to a housing of the agricultural metering system. The releasable bearing coupler includes a shaft configured to be disposed through an opening in the housing and to engage a bearing, wherein the bearing is configured to be disposed within a recess of the meter roller to facilitate rotation of the meter roller about the shaft and to couple the meter roller to the housing via contact with the shaft. The releasable bearing coupler includes a locking segment configured to selectively interlock with a corresponding locking feature of the housing to secure the releasable bearing coupler to the housing.

First claim

The invention claimed is:

1. An agricultural metering system, comprising:
a releasable bearing coupler configured to selectively couple a meter roller to a housing of the agricultural metering system, wherein the releasable bearing coupler comprises:
a shaft configured to be disposed through an opening in the housing and to engage a bearing, wherein the bearing is configured to be disposed within a recess of the meter roller to facilitate rotation of the meter roller about the shaft and to couple the meter roller to the housing via contact with the shaft; and
a locking segment configured to selectively interlock with a corresponding locking feature of the housing to secure the releasable bearing coupler to the housing.

2. The agricultural metering system of claim 1 , wherein the releasable bearing coupler comprises the bearing.

3. The agricultural metering system of claim 2 , wherein the bearing is configured to be disposed through the opening in the housing.

4. The agricultural metering system of claim 1 , wherein the locking segment is configured to selectively interlock with the locking feature via rotation of the releasable bearing coupler.

5. The agricultural metering system of claim 4 , wherein the releasable bearing coupler comprises a grip segment configured to facilitate rotation of the releasable bearing coupler.

6. The agricultural metering system of claim 5 , wherein the grip segment is configured to be positioned outside of the housing while the meter roller is coupled to the housing.

7. The agricultural metering system of claim 1 , comprising a meter roller cartridge having the housing.

8. The agricultural metering system of claim 7 , wherein the releasable bearing coupler is configured to selectively couple the meter roller to the housing on a longitudinal side of the meter roller cartridge opposite a drive shaft side.

9. An agricultural metering system, comprising:
a releasable bearing coupler configured to selectively couple a meter roller to a housing, wherein the releasable bearing coupler comprises:
a shaft configured to be disposed through an opening in the housing;
a bearing selectively coupled to the shaft, wherein the bearing is configured to engage a recess of the meter roller to couple the meter roller to the housing via contact with the shaft, and the bearing is configured to facilitate rotation of the meter roller about the shaft; and
a locking segment configured to selectively interlock with a corresponding locking feature of the housing to secure the releasable bearing coupler to the housing.

10. The agricultural metering system of claim 9 , wherein the bearing comprises a ball bearing.

11. The agricultural metering system of claim 9 , comprising a meter roller cartridge having the housing.

12. The agricultural metering system of claim 9 , wherein the locking segment of the releasable bearing coupler comprises at least one protrusion configured to engage at least one locking recess of the locking feature.

13. The agricultural metering system of claim 9 , wherein the releasable bearing coupler comprises a grip segment, wherein the grip segment is configured to be positioned outside of the housing while the meter roller is coupled to the housing.

14. The agricultural metering system of claim 13 , wherein the locking segment of the releasable bearing coupler comprises blocking protrusions configured to block rotation of the releasable bearing coupler relative to the housing.
