Abstract

A sweep auger system having a driveshaft with auger fighting and a backboard extending a length from an inward end to an outward end. An input of a gearbox is connected to an outward end of the drive shaft and a sweep wheel having a plurality of notches, arms and feet is connected to an output of the gearbox. A drive shield is placed around a rearward side of the sweep wheel that forms a channel that is configured to capture grain agitated by the drive wheel. A guide plate is connected to the gearbox and covers a portion of the gearbox. The guide plate angles from an upper outward edge downward and forward to a lower inward edge that is configured to urge the grain captured within the channel of the drive shield to move in front of the sweep auger system reducing grain left in the grain bin.

First claim

What is claimed:

1. A system for unloading grain out of a grain bin, comprising:
a sweep;
the sweep extending a length from an inward end to an outward end;
the sweep having a forward side and a rearward side;
a gearbox;
the gearbox positioned adjacent the outward end of the sweep;
a wheel;
the wheel positioned adjacent the outward end of the sweep;
a drive shield;
the drive shield positioned adjacent the outward end of the sweep;
wherein the drive shield forms a pocket;
wherein the drive shield has a shape such that grain moved within the pocket by rotation of the wheel is directed into a path of the sweep; and
wherein the drive shield includes an inner side wall that extends forward and inward at an angle relative to the length of the sweep.

2. The system of claim 1 , wherein the drive shield includes a back wall that extends approximately parallel to the length of the sweep.

3. The system of claim 1 , wherein the drive shield includes an outer side wall that extends approximately perpendicular to the length of the sweep.

4. The system of claim 1 , wherein the drive shield is formed of an inner portion and an outer portion that are connected together to form the drive shield.

5. The system of claim 1 , wherein:
the sweep has a drive shaft with flighting extending around the drive shaft; and
the sweep has a backboard positioned rearward of the drive shaft.

6. The system of claim 1 ,
wherein the sweep has a drive shaft; and
wherein the gearbox operably connects the drive shaft with the wheel.

7. The system of claim 1 , wherein the sweep has a drive shaft with flighting extending around the drive shaft; and
wherein the gearbox operably connects the drive shaft with the wheel.

8. The system of claim 1 , wherein the gearbox is positioned at least partially within the pocket of the drive shield.

9. The system of claim 1 , wherein the sweep is an auger sweep.

10. A system for unloading grain out of a grain bin, comprising:
a sweep;
the sweep extending a length from an inward end to an outward end;
the sweep having a forward side and a rearward side;
a gearbox;
the gearbox positioned adjacent the outward end of the sweep;
a wheel;
the wheel positioned adjacent the outward end of the sweep;
a drive shield;
the drive shield positioned adjacent the outward end of the sweep;
wherein the drive shield forms a pocket;
wherein the drive shield has a shape such that grain moved within the pocket by rotation of the wheel is directed into a path of the sweep;
wherein the drive shield includes an outer side wall;
wherein the position of the outer side wall is adjustable.

11. A system for unloading grain out of a grain bin, comprising:
a sweep;
the sweep extending a length from an inward end to an outward end;
the sweep having a forward side and a rearward side;
a gearbox;
the gearbox positioned adjacent the outward end of the sweep;
a wheel;
the wheel positioned adjacent the outward end of the sweep;
a drive shield;
the drive shield positioned adjacent the outward end of the sweep;
wherein the drive shield forms a pocket;
wherein the drive shield has a shape such that grain moved within the pocket by rotation of the wheel is directed into a path of the sweep;
wherein the drive shield includes an outer side wall;
wherein the outer side wall is configured to operably connect to a back wall of the drive shield at a plurality of different positions to facilitate lateral adjustment of the outer side wall.

12. A system for unloading grain out of a grain bin, comprising:
a sweep;
the sweep extending a length from an inward end to an outward end;
the sweep having a forward side and a rearward side;
a gearbox;
the gearbox positioned adjacent the outward end of the sweep;
a wheel;
the wheel positioned adjacent the outward end of the sweep;
a drive shield;
the drive shield positioned adjacent the outward end of the sweep;
wherein the drive shield forms a pocket;
wherein the drive shield has a shape such that grain moved within the pocket by rotation of the wheel is directed into a path of the sweep;
wherein the drive shield includes an outer side wall;
wherein the outer side wall is configured to operably connect at an infinite number of positions between an inner most position and an outer most position.

13. A system for unloading grain out of a grain bin, comprising:
a sweep;
the sweep extending a length from an inward end to an outward end;
the sweep having a forward side and a rearward side;
a wheel;
the wheel positioned adjacent the outward end of the sweep;
a drive shield;
the drive shield positioned adjacent the outward end of the sweep;
wherein the drive shield forms a pocket;
wherein the drive shield has a shape such that grain moved within the pocket by rotation of the wheel is directed into a path of the sweep;
wherein the drive shield includes an outer side wall;
wherein the drive shield includes an inner side wall;
wherein the outer side wall extends forward at a first angle relative to the length of the sweep;
wherein the inner side wall extends forward at a second angle relative to the length of the sweep;
wherein the first angle is different from the second angle.

14. The system of claim 13 , wherein the first angle and the second angle differ by 20 degrees or more.

15. The system of claim 13 , wherein the inner side wall extends forward and inward from a rear end of the pocket.

16. The system of claim 13 , wherein the inner side wall includes a first portion that extends forward at the second angle;
wherein the inner side wall includes a second portion that extends forward from the first portion at a third angle;
wherein the third angle is different from the second angle.
