Abstract
A metering system for a seeding machine is provided. The metering system includes selectively powered metering sections operable to individually allow or restrict seed dispensation. A damper arrangement is also provided so that pneumatic conveying of the particulate within the machine is consistently maintained when particulate flow is varied between the metering sections.
Claims42
A metering system for use in a particulate delivery system, wherein the particulate delivery system includes a rotatable drive shaft and a tank containing particulate, said metering system including a plurality of selectively-powered particulate metering sections, each of said particulate metering sections comprising:
- a rotatable metering roller configured to receive particulate from the tank,
- said metering roller operable to dispense the particulate when rotated,
- said metering roller operable to prevent particulate dispensation when not rotated;
- a rotatable metering wheel, said metering roller being configured to rotate with the metering wheel;
- a rotatable engagement wheel operable to rotate the metering wheel and thereby the metering roller when the engagement wheel and the metering wheel are drivingly interengaged;
- a drive wheel configured to be mounted on the drive shaft to rotate therewith,
- said drive wheel engaging the engagement wheel;
- and
- a control arm shiftably supporting the engagement wheel for shifting movement into and out of driving engagement with the metering wheel, such that particulate dispensation is prevented by the metering roller when the engagement wheel is drivingly disengaged from the metering wheel and particulate is dispensed by the metering roller when the engagement wheel is shifted into driving engagement with the metering wheel.
A particulate delivery system comprising:
- a tank containing particulate;
- a rotatable drive shaft;
- and
- a metering system, said metering system including a plurality of selectively-powered particulate metering sections, each of said metering sections including
- a rotatable metering roller in communication with the tank,
- said metering roller operable to dispense the particulate when rotated,
- said metering roller operable to prevent particulate dispensation when not rotated;
- a rotatable metering wheel, said metering roller being configured to rotate with the metering wheel;
- a rotatable engagement wheel operable to rotate the metering wheel and thereby the metering roller when the engagement wheel and the metering wheel are drivingly interengaged;
- a drive wheel mounted on the drive shaft to rotate therewith,
- said drive wheel engaging the engagement wheel;
- and
- a control arm shiftably supporting the engagement wheel for shifting movement into and out of driving engagement with the metering wheel, such that particulate dispensation is prevented by the metering roller when the engagement wheel is drivingly disengaged from the metering wheel and particulate is dispensed by the metering roller when the engagement wheel is shifted into driving engagement with the metering wheel.
A particulate delivery system comprising:
- a tank containing particulate;
- a plurality of particulate-transporting lines;
- a metering system including a plurality of particulate metering sections,
- each of said metering sections being associated with a respective one of the particulate-transporting lines and including a metering device configured to control dispensation of the particulate from the tank to the respective line;
- an airflow generator in communication with the particulate-transporting lines so as to provide pneumatic conveying of the particulate within the lines;
- and
- a plurality of damper assemblies, each of which is associated with a respective one of the particulate-transporting lines,
- each of said damper assemblies being operable to selectively restrict airflow within the respective particulate-transporting line responsive to variations in metering of particulate to the respective particulate-transporting line.
