The sweep conveyor assembly has a sweep conveyor (S) for transporting material (74) inside the silo (S) or granary towards the centre of the floor (71) where it can be discharged by the discharge apparatus (1), a holder (H), and a link mechanism (8) for connecting the sweep conveyor (S) to the holder (H), and in turn having a connection link (L) with a first end (83) and a second end (84). The first end (83) is connected to the holder (H) at a fixed pivot point and the sweep conveyor (S) is connected to the second end (84) of the connection link (L) at a movable pivot point. The connection link (L) rotates about the fixed pivot point, forming a first angle () between the connection link (L) and the holder (H), and the sweep conveyor (S) rotates about the movable pivot point, forming a second angle () between the sweep conveyor (S) and the connection link (L). The link mechanism (8) controls a ratio between the first angle () and the second angle (), with a magnitude of the first angle () and second angle () controlled by an angular position of the sweep conveyor (S).

A full floor sweep system having a skeletonized head section to facilitate removal of grain from a grain bin. The sweep system having an elongated body extending a length between an inward end and an outward end and having a leading side and a trailing side. The elongated body is connected to a pivot point at the center of the grain bin and is configured to rotate around the pivot point. An agitator is connected to the outward end of the elongated body and is configured to agitate grain as the elongated body rotates around the pivot point. The agitator includes an impeller that is connected to a shaft that extends through the elongated body. A scraper is positioned at the outward end of the elongated body and is configured to move grain into the path of the elongated body.

A sweep auger system having a driveshaft with auger flighting 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 sweep 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.
