Abstract
A meter roller for an agricultural metering system includes multiple flutes and corresponding recesses. The flutes and the corresponding recesses are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller. The meter roller also includes multiple air passages formed within a body of the meter roller. Each air passage is fluidly coupled to a central cavity of the meter roller and extends to a base of a respective recess, and the air passage is configured to flow air from the central cavity into the respective recess.
Claims13
A meter roller for an agricultural metering system, comprising:
- a plurality of flutes and a corresponding plurality of recesses, wherein the plurality of flutes and the corresponding plurality of recesses are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller;
- and
- a plurality of air passages formed within a body of the meter roller, wherein each air passage of the plurality of air passages is fluidly coupled to a central cavity of the meter roller and extends to a respective recess of the plurality of recesses, and each air passage of the plurality of air passages is configured to flow air from the central cavity into the respective recess;
- wherein the plurality of air passages comprises a first set of air passages extending to a first recess of the plurality of recesses and a second set of air passages extending to a second recess of the plurality of recesses;
- and
- wherein the first set of air passages are distributed along a rotational axis of the meter roller, or the second set of air passages are distributed along the rotational axis of the meter roller, or a combination thereof.
3 more elements
A debris removal system for an agricultural metering system, comprising:
- at least one air passage extending to a metering cavity of the agricultural metering system, wherein the at least one air passage is directed toward a recess of a meter roller disposed within the metering cavity and configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller;
- a valve assembly fluidly coupled to the at least one air passage, wherein the valve assembly is configured to control an airflow through the at least one air passage;
- and
- a controller comprising a processor and a memory, wherein the controller is communicatively coupled to the valve assembly, the controller is configured to output an output signal to the valve assembly indicative of instructions to selectively provide the airflow to the at least one air passage, and the controller is configured to:
- receive a first input signal indicative of a weight of the flowable particulate material within the storage tank and instruct the valve assembly, via the output signal, to provide the airflow to the at least one air passage in response to determining that a difference between the weight and an expected weight is greater than a threshold value;
- or
- receive a second input signal indicative of an obstruction within the recess of the meter roller and instruct the valve assembly, via the output signal, to provide the airflow to the at least one air passage in response to identifying the obstruction within the recess;
- or
- a combination thereof.
6 more elements
An agricultural metering system, comprising:
- a housing having a metering cavity;
- a meter roller disposed within the metering cavity of the housing, wherein the meter roller comprises a plurality of flutes and a corresponding plurality of recesses, and the plurality of flutes and the corresponding plurality of recesses are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller;
- and
- a debris removal system comprising a plurality of air passages, wherein each air passage of the plurality of air passages extends through a body of the meter roller from a central cavity of the meter roller to a respective recess of the plurality of recesses of the meter roller, and the plurality of air passages is configured to flow air from the central cavity into the plurality of recesses;
- wherein the debris removal system comprises an air source configured to provide the flow of the air to the central cavity to enable the flow of the air to pass through the plurality of air passages concurrently from the central cavity into the plurality of recesses.
