Internal tank augers for air seeder hoppers
View Patent ↗An air seeder is provided having at least one container with a trough in the bottom floor. Preferably, the floor is formed with a v-shaped configuration converging at a metering mechanism. An auger is rotatably mounted in the trough to move particulate material to the metering mechanism located at a distal end of the container. The auger is powered by a motor mounted on the distal end of the auger opposite the metering mechanism. A remote fan mechanism is provided to deliver a supply of air to the metering mechanism through a pair of conveying tubes. Optionally, a sensor is provided to control the operation of the auger so that the auger only operates when it is needed.
1. A method of conveying particulate material for distribution in the ground, the method comprising the steps of:
conveying a first particulate material in a first container with a first auger along a first trough incorporated into a bottom floor of the first container and in a direction towards a first metering mechanism located at an end of the first container,
conveying a second particulate material in a second container with a second auger along a second trough incorporated into a bottom floor of the second container and in a direction towards a second metering mechanism located at an end of the second container, the first metering mechanism located adjacent to the second metering mechanism; and
delivering the first and second particulate material for distribution to the ground.
2. The method as recited in claim 1 , further including the steps of;
detecting a shortage of particulate material to be dispensed by the first metering mechanism; and
initiating a motor to drive rotation of the first auger to convey the first particulate material in the first container to the first metering mechanism in response to detecting the shortage of the particulate material.
3. The method as recited in claim 2 , wherein the step of initiating the motor is in response to a signal from an optical sensor indicating a level of the first particulate material in the first container.
4. The method as recited in claim 2 , wherein the step of initiating the motor is in response to a signal from a sensor indicating a shortage of the first particulate material to be dispensed through the first metering mechanism.
5. The method as recited in claim 2 , wherein the step of initiating the motor is in response to sensing a lowered torque requirement to effect rotation of the first auger.
6. The method as recited in claim 2 , further comprising the step of: stopping rotation of the first auger in response to detecting a sufficient supply of the first particulate material at the first metering mechanism.
7. A method of conveying particulate material for distribution in the ground, the method comprising the steps of:
conveying a first particulate material in a first container with a first auger along a first trough incorporated into a bottom floor of the first container and in a direction towards a first metering mechanism,
conveying a second particulate material in a second container with a second auger along a second trough incorporated into a bottom floor of the second container and in a direction towards a second metering mechanism, the first metering mechanism located adjacent to the second metering mechanism;
delivering the first and second particulate material for distribution to the ground;
sensing a lowered torque of the first auger; and
initiating a motor to drive rotation of the first auger in response to the sensed lowered torque of the first auger.
8. The method as recited in claim 7 , further including the steps of;
detecting a shortage of the first particulate material to be dispensed by the first metering mechanism; and
initiating a motor to drive rotation of the first auger to convey the first particulate material in the first container to the first metering mechanism in response to detecting the shortage of the particulate material.
9. The method as recited in claim 8 , wherein the step of initiating the motor is in response to a signal from an optical sensor indicating a level of the first particulate material in the first container.
10. The method as recited in claim 8 , wherein the step of initiating the motor is in response to a signal from a sensor indicating a shortage of the first particulate material to be dispensed through the first metering mechanism.
11. The method as recited in claim 8 , wherein the step of initiating the motor is in response to sensing a lowered torque requirement to effect rotation of the first auger.
12. The method as recited in claim 8 , further comprising the step of: stopping rotation of the first auger in response to detecting a sufficient supply of the first particulate material at the first metering mechanism.
