Abstract
The invention is a low-profile bin sweep for mounting on the end of a portable grain auger and useful for cleaning out flat-bottomed grain bins or piles of grain.
It can also be used for other granular products. The sweep is a screw conveyor and is typically attached to a portable grain auger that is a screw conveyor inside a tube. In order to maintain a low profile, the attachment apparatus for the bin sweep is located below the inlet of the auger. This allows the bin sweep to stay attached to the auger while the auger is transported or being moved into position.
It is also convenient for storing the sweep while the auger is being used in a situation where the bin sweep is not needed.
It can also be used for other granular products. The sweep is a screw conveyor and is typically attached to a portable grain auger that is a screw conveyor inside a tube.

LOW PROFILE BIN SWEEP
ABSTRACT OF THE DISCLOSURE
The invention is a low-profile bin sweep for mounting on the end of a portable grain auger and useful for cleaning out flat-bottomed grain bins or piles of grain.
It can also be used for other granular products. The sweep is a screw conveyor and is typically attached to a portable grain auger that is a screw conveyor inside a tube. In order to maintain a low profile, the attachment apparatus for the bin sweep is located below the inlet of the auger. This allows the bin sweep to stay attached to the auger while the auger is transported or being moved into position.
It is also convenient for storing the sweep while the auger is being used in a situation where the bin sweep is not needed.
LOW PROFILE BIN SWEEP
This invention pertains to a screw conveyor used to transfer grain and other granular products such as fertilizer into the inlet of a portable grain auger.
It would most typically be used to load grain from a flat-bottomed storage bin or free standing grain pile into a truck or trailer.
BACKGROUND OF THE INVENTION
One of the most common methods for elevating grain on farms is the portable screw conveyor or grain auger. The augers are simple machines that can efficiently move high volumes of grain. Typically, in flat-bottomed grain bins, a bin sweep such as a described in Canadian Patent 1,196,762 or United States Patent 4,619,577 is utilized for cleaning out the bin. The bin sweep is mounted on top of the lower end of the auger. There are a number of problems with this system. One issue is that because the bin sweep apparatus is so large, the bin sweep must be removed from the end of the portable auger when the auger is entering or exiting the grain bin. In addition, the bin sweep must also be removed from the portable auger when the auger is used in an application where a bin sweep is not required. This causes significant additional manual labor for the operator. A second problem is that because the bin sweep is mounted on the top of the lower end of the portable auger, the sweep fighting requires a universal joint in order for the sweep flighting to properly clean the floor area. With the universal joint in the bin sweep fighting and the additional direction change for the grain, there is a significant amount of extra grain dust that is raised during the operation of the bin sweep, lowering the air quality in the bin. Because the farmer is typically in the bin during the operation of the bin sweep, this extra dust is a health hazard.

3. Canada Patent 2,312,068 Bin Sweep Accessory ADVANCES OF THE INVENTION
The invention addresses some of the short-comings of the current technology.
The low-profile bin sweep is mounted in such a manner that there is no need to have a universal joint added to the fighting of the bin sweep. In addition, because of the lower mounting of the drive motor on the low-profile bin sweep, the overall length of the fighting can be reduced. The combination of eliminating a universal joint as well as shortening the fighting results in a significant decrease in the amount of dust raised by the bin sweep. This increases the air quality for the operator.
Another significant advantage of the invention is that it is very compact.
Because of the small size of the unit, the low-profile bin sweep can typically remain attached to the portable auger even when the auger is used in an application where a bin sweep is not needed. This is a tremendous advantage for the operator and saves a significant amount of labor.

DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the invention is illustrated in Figure 1 where a portable auger unit 1 and a low-profile sweep unit 2 are shown. The portable auger unit 1 is similar to the conventional augers currently used in the industry.
Auger unit 1 has an auger tube 3 that is typically supported by auger wheels
4, auger frame 5 and a raise/lower device 6. The grain moving items of the auger portion are the auger tube 3 and the auger screw conveyor 7. The auger screw conveyor 7 is shown at the auger inlet 8 and the auger screw conveyor 7 extends inside the auger tube 3 from the auger inlet 8 up to the location of the auger discharge 9. Sweep unit 2 is shown engaged in a grain pile 10. The grain is moved toward the auger inlet 8 by the sweep unit 2. Grain is then delivered to the lower end of the auger screw conveyor 7 and moved upward through the auger tube 3 by the auger screw conveyor 7. The grain drops out of the auger tube 3 at the auger discharge 9 and into a waiting truck 11. The grain pile 10 is a loading area that might be a flat-bottomed bin or a free-standing grain pile.
Figure 2 and Figure 3 show additional details of the sweep unit 2 attached to the lower end of the auger tube 3 and more specifically at auger inlet frame 12.
For clarity, the auger screw conveyor 7 has been removed from Figure 2 and from Figure 3. Sweep screw conveyor 13 is attached to the shaft of the sweep motor 14 at shaft connection 15. Sweep motor 14 is pivotally connected to link 16 at link-motor pivot 17. Link-motor pivot 17 allows rotation about a vertical axis as well as some limited rotation about a horizontal axis. This additional rotation about a horizontal axis is designed to allow up and down movement, to enable the sweep screw conveyor 13 to follow the plane of the floor 18 and properly clean the grain from floor 18. Link 16 is pivotally attached below the auger inlet frame 12 at auger-link pivot 19. Auger-link pivot 19 is a substantially vertical axis but will vary from vertical, depending on the orientation of the auger tube 3.
Auger-link pivot 19 is also designed to allow additional movement to enable the sweep screw conveyor 13 to follow the plane of the floor 18. The angular relationship between the sweep screw conveyor 13 and the auger tube 3 will vary, depending on a number of things not the least of which is the angle setting of the auger tube 3.
One method of achieving the connection between the auger inlet frame 12 and the link-motor pivot is to use an angled mount plate 20 in combination with a straight mount plate 21. The vertical portion of the angled mount plate 20 is attached to the lower members of the auger inlet frame 12 and also to the straight mount plate 21. The horizontal portion of the angled mount plate 20, has a hole in it that forms part of the auger-link pivot 19. The straight mount plate 21 is attached to the auger inlet frame 12 and also attached to the angled mount plate 20. Straight mount plate 21 also has a hole in it that forms part of the auger-link pivot 19. By properly constructing the angled mount plate 20 and the straight mount plate 21, the vertical portion of the angled mount plate 20 provides a stop to limit the rotation of the link 16 as can be seen in Figure 4.
Figure 2 and Figure 3 show the sweep screw conveyor 13 oriented away from the auger tube 3. This is the intermediate position for the sweep screw conveyor 13 relative to the auger tube 3. The link 16 is able to pivot about auger-link pivot 19 from an approximate extreme position shown in Figure 4 to an approximate extreme position shown in Figure 6. In Figure 4, link 16 is rotated to the furthest extreme counter-clockwise position and has made contact with the vertical portion of angled plate 20. In Figure 5, link 16 is rotated to an oblique angle relative to the auger tube 3, as is typical as the sweep screw conveyor 13 makes its way around the lower end of the auger tube 3. In Figure 6, link 16 is rotated to the furthest extreme clockwise position and has made contact with the vertical portion of angled plate 20 on the opposite side compared to the orientation in Figure 4. Of course, in all of the positions of link 16, the sweep motor 14 complete with the sweep screw conveyor 13, is free to rotate about the link-motor pivot 17. Figure 4 shows the sweep screw conveyor 13 at a position approximately ninety degrees relative to link 16. Figure 5 shows the sweep screw conveyor 13 at a position approximately aligned with link 16. Figure 4 shows the sweep screw conveyor 13 rotated about link 16 to a position parallel to and alongside of auger tube 3. This would typically be the starting position for the sweep screw conveyor 13 when beginning the process of cleaning out the floor 18 of a flat-bottomed bin.
Figure 7 shows a side view of the sweep screw conveyor 13 in a similar orientation relative to the auger tube 3 as shown in Figure 4 or in Figure 6.
The sweep screw conveyor 13 is shown rotated all the way counter-clockwise (when viewed from above) about the lower end of auger tube 3 in Figure 4, while keeping the sweep screw conveyor in contact with the bin floor 18. The sweep screw conveyor 13 is shown rotated all the way clockwise (when viewed from above) about the lower end of auger tube 3 in Figure 6.
Figure 8 shows the sweep screw conveyor 13 rotated about the horizontal axis at link-motor pivot 17 and supported in this position by a transport cradle 22.
This feature of the invention allows the sweep screw conveyor 13 to be approximately aligned with the auger tube 3, securing the sweep screw conveyor 13 to be stored for long periods in this orientation. It also allows the unit the capability of being transported in this manner. In addition, this combination is a very compact unit and is able to fit into the doorway of many flat-bottomed grain bins.
This means that the sweep screw conveyor 13 can be carried into position in a grain bin by the auger unit 1 and eliminate significant manual labor for the operator.
The transport position of the auger unit 1 complete with the sweep unit 2 and the sweep screw conveyor 13 is shown in Figure 9.
Additional items that add to the performance of the sweep screw conveyor 13 are shown in Figure 5. The back plate 23 is pivotally attached to the axis of the sweep screw conveyor 13. The back plate 23 follows the sweep screw conveyor 13 and cleans the floor 18. A sweep driver 24 is rigidly attached to the sweep screw conveyor 13 and provides a forward driving force to the screw conveyor 13. As the screw conveyor 13 rotates, the sweep driver 24 contacts the floor with each rotation and the friction between the sweep driver 24 and the floor propels the screw conveyor 13 forward, into the grain pile 10. Both the back plate 23 and the sweep driver 24 are common in the bin sweep industry.
THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVLEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A sweep auger system for moving granular material, where the sweep apparatus utilizes a pivot coupling means to attach the sweep auger system to the intake end of a portable screw conveyor auger, said pivot coupling means being substantially located below the inlet of the portable auger.
2. A system as defined in claim 1, wherein said coupling means includes an arm, a primary pivot located under the centerline of the screw conveyor of the portable auger, mounted in such a manner to allow said arm rotation limited to approximately 180 degrees 3. A system as defined in claim 2 wherein there is framework below the intake end of the portable auger that supports the lower end of the portable auger in a slightly raised position to allow said arm to rotate and pass under the outer, lower extremity of the portable auger.
4. A system as defined in claim 3 wherein the secondary pivot of the said arm is pivotally attached to the sweep auger drive motor, said pivot allowing rotation about a vertical axis and a horizontal axis.
Figure 2 and Figure 3 show additional details of the sweep unit 2 attached to the lower end of the auger tube 3 and more specifically at auger inlet frame 12.
For clarity, the auger screw conveyor 7 has been removed from Figure 2 and from Figure 3. Sweep screw conveyor 13 is attached to the shaft of the sweep motor 14 at shaft connection 15. Sweep motor 14 is pivotally connected to link 16 at link-motor pivot 17. Link-motor pivot 17 allows rotation about a vertical axis as well as some limited rotation about a horizontal axis. This additional rotation about a horizontal axis is designed to allow up and down movement, to enable the sweep screw conveyor 13 to follow the plane of the floor 18 and properly clean the grain from floor 18. Link 16 is pivotally attached below the auger inlet frame 12 at auger-link pivot 19. Auger-link pivot 19 is a substantially vertical axis but will vary from vertical, depending on the orientation of the auger tube 3.
Auger-link pivot 19 is also designed to allow additional movement to enable the sweep screw conveyor 13 to follow the plane of the floor 18. The angular relationship between the sweep screw conveyor 13 and the auger tube 3 will vary, depending on a number of things not the least of which is the angle setting of the auger tube 3.
One method of achieving the connection between the auger inlet frame 12 and the link-motor pivot is to use an angled mount plate 20 in combination with a straight mount plate 21. The vertical portion of the angled mount plate 20 is attached to the lower members of the auger inlet frame 12 and also to the straight mount plate 21. The horizontal portion of the angled mount plate 20, has a hole in it that forms part of the auger-link pivot 19. The straight mount plate 21 is attached to the auger inlet frame 12 and also attached to the angled mount plate 20. Straight mount plate 21 also has a hole in it that forms part of the auger-link pivot 19. By properly constructing the angled mount plate 20 and the straight mount plate 21, the vertical portion of the angled mount plate 20 provides a stop to limit the rotation of the link 16 as can be seen in Figure 4.
Figure 2 and Figure 3 show the sweep screw conveyor 13 oriented away from the auger tube 3. This is the intermediate position for the sweep screw conveyor 13 relative to the auger tube 3. The link 16 is able to pivot about auger-link pivot 19 from an approximate extreme position shown in Figure 4 to an approximate extreme position shown in Figure 6. In Figure 4, link 16 is rotated to the furthest extreme counter-clockwise position and has made contact with the vertical portion of angled plate 20. In Figure 5, link 16 is rotated to an oblique angle relative to the auger tube 3, as is typical as the sweep screw conveyor 13 makes its way around the lower end of the auger tube 3. In Figure 6, link 16 is rotated to the furthest extreme clockwise position and has made contact with the vertical portion of angled plate 20 on the opposite side compared to the orientation in Figure 4. Of course, in all of the positions of link 16, the sweep motor 14 complete with the sweep screw conveyor 13, is free to rotate about the link-motor pivot 17. Figure 4 shows the sweep screw conveyor 13 at a position approximately ninety degrees relative to link 16. Figure 5 shows the sweep screw conveyor 13 at a position approximately aligned with link 16. Figure 4 shows the sweep screw conveyor 13 rotated about link 16 to a position parallel to and alongside of auger tube 3. This would typically be the starting position for the sweep screw conveyor 13 when beginning the process of cleaning out the floor 18 of a flat-bottomed bin.
Figure 7 shows a side view of the sweep screw conveyor 13 in a similar orientation relative to the auger tube 3 as shown in Figure 4 or in Figure 6.
The sweep screw conveyor 13 is shown rotated all the way counter-clockwise (when viewed from above) about the lower end of auger tube 3 in Figure 4, while keeping the sweep screw conveyor in contact with the bin floor 18. The sweep screw conveyor 13 is shown rotated all the way clockwise (when viewed from above) about the lower end of auger tube 3 in Figure 6.
Figure 8 shows the sweep screw conveyor 13 rotated about the horizontal axis at link-motor pivot 17 and supported in this position by a transport cradle 22.
This feature of the invention allows the sweep screw conveyor 13 to be approximately aligned with the auger tube 3, securing the sweep screw conveyor 13 to be stored for long periods in this orientation. It also allows the unit the capability of being transported in this manner. In addition, this combination is a very compact unit and is able to fit into the doorway of many flat-bottomed grain bins.
This means that the sweep screw conveyor 13 can be carried into position in a grain bin by the auger unit 1 and eliminate significant manual labor for the operator.
The transport position of the auger unit 1 complete with the sweep unit 2 and the sweep screw conveyor 13 is shown in Figure 9.
Additional items that add to the performance of the sweep screw conveyor 13 are shown in Figure 5. The back plate 23 is pivotally attached to the axis of the sweep screw conveyor 13. The back plate 23 follows the sweep screw conveyor 13 and cleans the floor 18. A sweep driver 24 is rigidly attached to the sweep screw conveyor 13 and provides a forward driving force to the screw conveyor 13. As the screw conveyor 13 rotates, the sweep driver 24 contacts the floor with each rotation and the friction between the sweep driver 24 and the floor propels the screw conveyor 13 forward, into the grain pile 10. Both the back plate 23 and the sweep driver 24 are common in the bin sweep industry.
