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. In an air seeder having a frame, a pair of ground engaging wheels, at least one container having an outer end wall, an opposite inner end wall, and side walls connecting the outer end wall and the opposite inner end wall, and a metering mechanism for dispensing particulate product from said at least one container, the improvement comprising:
said at least one container having a trough in incorporated into a bottom floor and an auger rotatably mounted in said trough for transporting said particulate product along said floor to said metering mechanism, wherein said floor is shaped in v-shaped configuration converging at said metering mechanism; and
a motor mounted on a distal end of said auger relative to said metering mechanism to rotate said auger and convey said particulate product said metering mechanism, said metering mechanism being located at an end of said at least one container.
2. The air seeder of claim 1 , wherein said at least one container is formed in a double v-shaped configuration to facilitate movement of said particulate product into the auger for conveyance of said particulate product to said metering mechanism.
3. The air seeder of claim 2 , wherein said trough is located in a lower apex of each of said v-shaped configurations, each said trough having an auger rotatably mounted therein for transporting said particulate product along said floor to said metering mechanism.
4. In an air seeder having a frame, a pair of ground engaging wheels, at least one container having an outer end wall, an opposite inner end wall, and side walls connecting the outer end wall and the opposite inner end wall, and a metering mechanism for dispensing particulate product from said at least one container, the improvement comprising:
said at least one container having a trough incorporated into a bottom floor and an auger rotatably mounted in said trough for transporting said particulate product along said floor to said metering mechanism;
a motor mounted on a distal end of said auger relative to said metering mechanism to rotate said auger and convey said particulate product said metering mechanism, said metering mechanism being located at an end of said at least one container;
a sensor in said metering mechanism to detect a shortage of said particulate product being dispensed through said metering mechanism; and
a controller to initiate rotation of said auger to convey said particulate product from said at least one container to fill said metering mechanism.
5. The air seeder of claim 4 , wherein said sensor stops said motor when a sufficient amount of said particulate product is present in said metering mechanism.
6. In an air seeder having a frame, a pair of ground engaging wheels, at least one container having an outer end wall, an opposite inner end wall, and side walls connecting the outer end wall and the opposite inner end wall, and a metering mechanism for dispensing particulate product from said at least one container, the improvement comprising:
said at least one container having a trough incorporated into a bottom floor and an auger rotatably mounted in said trough for transporting said particulate product along said floor to said metering mechanism;
a motor mounted on a distal end of said auger relative to said metering mechanism to rotate said auger and convey said particulate product to said metering mechanism, said metering mechanism being located at an end of said at least one container; and
an optical sensor located in said at least one container to sense a level of said particulate product within said at least one container, said optical sensor triggering the start of said motor and subsequent rotation of said auger to deliver said particulate product to said metering mechanism.
7. In an air seeder having a frame, a pair of ground engaging wheels, at least one container having an outer end wall, an opposite inner end wall, and side walls connecting the outer end wall and the opposite inner end wall, and a metering mechanism for dispensing particulate product from said at least one container, the improvement comprising:
said at least one container having a trough incorporated into a bottom floor and an auger rotatably mounted in said trough for transporting said particulate product along said floor to said metering mechanism; and
a motor mounted on a distal end of said auger relative to said metering mechanism to rotate said auger and convey said particulate product to said metering mechanism, said metering mechanism being located at an end of said at least one container, wherein said auger is initiated in response to lowered torque to effect rotation of said auger as said particulate product drains from said at least one container.
