Abstract

An agricultural metering system includes a modular meter roller cartridge. The modular meter roller cartridge includes a meter roller. The modular meter roller cartridge further includes a housing rotatably supporting the meter roller. The housing is configured to selectively engage a meter box of the agricultural metering system to support the meter roller within the meter box while the housing is engaged with the meter box, and to selectively disengage the meter box.

First claim

1 . An agricultural metering system, comprising:
a modular meter roller cartridge, comprising:
a meter roller; and
a housing rotatably supporting the meter roller, wherein the housing is configured to selectively engage a meter box of the agricultural metering system to support the meter roller within the meter box while the housing is engaged with the meter box, and to selectively disengage the meter box.

2 . The agricultural metering system of claim 1 , wherein the modular meter roller cartridge comprises a releasable bearing coupler configured to selectively couple the meter roller to the housing.

3 . The agricultural metering system of claim 2 , comprising 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 a shaft of the releasable bearing coupler while the meter roller is coupled to the housing.

4 . The agricultural metering system of claim 2 , wherein the releasable bearing coupler comprises a locking segment configured to selectively interlock with a locking feature of the housing to couple the meter roller to the housing.

5 . The agricultural metering system of claim 1 , wherein the housing comprises a dividing slat configured to align with a meter roller ring while the meter roller is disposed within the housing, and the dividing slat and meter roller ring are configured to block product flow along the meter roller in a longitudinal direction.

6 . The agricultural metering system of claim 1 , wherein the meter roller comprises a driven shaft configured to non-rotatably and selectively couple to a drive shaft while the housing is engaged with the meter box.

7 . The agricultural metering system of claim 1 , wherein the modular meter roller cartridge comprises a drive shaft opening, and the drive shaft opening is configured to align with a driven shaft of the meter roller while the meter roller is disposed within the housing.

8 . A method of manufacturing an agricultural metering system, comprising:
disposing a modular meter roller cartridge within an opening of a meter box, wherein the modular meter roller cartridge comprises a meter roller and a housing rotatably supporting the meter roller, and the housing is configured to selectively engage the meter box, to support the meter roller within the meter box, and to selectively disengage the meter box.

9 . The method of claim 8 , comprising disposing the meter roller within the housing via insertion of the meter roller through a meter roller opening.

10 . The method of claim 8 , comprising securing the meter roller to the housing via a releasable bearing coupler.

11 . The method of claim 10 , wherein securing the meter roller comprises inserting the releasable bearing coupler through a bearing opening of the housing.

12 . The method of claim 11 , wherein securing the meter roller comprises aligning a recess of the meter roller with the bearing opening.

13 . The method of claim 8 , comprising selectively securing the meter roller cartridge within the meter box via engagement of a latch.

14 . An agricultural metering system, comprising:
a meter box having an opening; and a modular meter roller cartridge configured to be inserted within the opening, wherein the modular meter roller cartridge comprises:
a meter roller; and
a housing rotatably supporting the meter roller, wherein the housing is configured to be selectively disposed within the meter box to support the meter roller within the meter box, and to be selectively removed from the meter box, and wherein a first cross-sectional shape of the housing substantially corresponds to a second cross-sectional shape of the opening to facilitate insertion and removal of the modular meter roller cartridge from the meter box.

15 . The agricultural metering system of claim 14 , wherein the meter box comprises a latch configured to selectively secure the modular meter roller cartridge within the meter box.

16 . The agricultural metering system of claim 14 , wherein the housing comprises a releasable bearing coupler opening on a first longitudinal side of the housing and a drive shaft opening on a second longitudinal side of the housing, opposite the first longitudinal side.

17 . The agricultural metering system of claim 16 , wherein the meter box comprises a drive shaft opening configured to align with the drive shaft opening in the second longitudinal side of the housing while the modular meter roller cartridge is disposed within the meter box.

18 . The agricultural metering system of claim 14 , comprising a drive shaft, wherein the drive shaft is configured to engage a driven shaft of the meter roller while the meter roller cartridge is disposed within the meter box.

19 . The agricultural metering system of claim 14 , wherein the housing comprises a dividing slat configured to interfere with a dividing ring of the meter roller to block product flow along the meter roller in a longitudinal direction.

20 . The agricultural metering system of claim 14 , wherein the housing comprises locking notches configured to interlock with a locking segment of a releasable bearing coupler to secure the meter roller to the housing.
