DESCRIPTION

(6) As noted above, this Bin wall cleaner for sweep conveyor overcomes numerous problems, such as:

(7) a) residual grain located near the bin wall out of reach of the sweep conveyor, and

(8) b) non-uniform bin wall distance.

(9) As shown in FIG. 1, the bin wall cleaner 100 can be attached to the distal end 10 of a sweep conveyor 5. For this technology, the sweep conveyor can comprise a belt conveyor, chain conveyor, or auger for transporting the grain. The bin wall cleaner 100 has a grain engagement member 102 having at least a first blade portion 115 that directs the seed toward the path of the sweep conveyor 5. The bin wall cleaner 100 has a proximal end 105 and a distal end 110. The proximal end 105 of the bin wall cleaner 100 is mounted to the end of the sweep conveyor 5 using a mounting bracket. As shown in the implement of FIG. 1, the mounting bracket 112 can be a hinge joint.

(10) The grain engagement member 102 of the bin wall cleaner 100 is moveable relative to the sweep. The grain engagement member 102 can be longitudinally extendable, pivotally movable about a vertical axis, or both longitudinally extendable and pivotally movable.

(11) The bin wall cleaner 100 is extendably mounted to the sweep conveyor 5 in order to direct grain that is outside the reach of the sweep conveyor into the sweep conveyor's path. The mounting bracket 112 allows the bin wall cleaner 100 to extend relative to the distal end 10 of the sweep conveyor 5. Alternatively, the bin wall cleaner can be mounted to the distal end 10 of the pivoting sweep conveyor 5 at an angle less than 90 from the distal end of the pivoting sweep conveyor. This angle can be a fixed angle or a variable angle.

(12) As shown in FIG. 2, the grain engagement member 102 can have multiple blade portions. FIG. 2 shows a grain engagement member 102 having a first blade portion 115 and a second blade portion 120. Each blade has a plurality of adjustment apertures 125. A fastener is received by respective adjustment apertures 125 of the first blade portion 115 and the second blade portion 120 to secure the two blade portions together at a fixed blade length. As such, the length of the grain engagement member 102 is adjustable by changing the selected adjustment apertures 125 to align between the first blade portion 115 and the second blade portion 120.

(13) The grain engagement member 102 extends and retracts from the distal end in order to extend the reach of the sweep conveyor 5 to the bin wall 30. In an embodiment with the bin wall cleaner 100 mounted at a fixed angle, the bin wall cleaner 100 can be extendable by varying the length of the grain engagement member 102, such as by telescoping the blade portions 115, 120. In an embodiment having a telescoping blade assembly, the telescoping blade assembly slides in on itself, allowing the blade portion to be longer or shorter and track with the distance between the distal end 10 of the sweep conveyor 5 and the interior surface of the bin wall 30.

(14) In an embodiment where the bin wall cleaner 100 is mounted to the sweep 5 at a variable angle, the grain engagement member 102 is extendable by increasing or decreasing the angle of the blade portions 115, 120 relative to the sweep. The bin wall cleaner 100 has a proximal end 105 that is extendably mounted to the distal end 10 of the sweep conveyor 5 by a mounting bracket 112. The mounting bracket 112 can be a hinge joint, allowing the bin wall cleaner 100 to pivotally mount to the distal end 10 of the sweep conveyor 5. The grain engagement member 102 has a distal end that extends towards the bin wall 30.

(15) A biasing member 150 maintains the bin wall cleaner 100 in its extended position. As illustrated, the biasing member 150 can comprise an actuator that is mounted to the sweep conveyor 5 and to the grain engagement member 102. The actuator can be a spring, hydraulic, pneumatic, or mechanical actuator. The biasing member 150 maintains the bin wall cleaner 100 in the extended orientation relative to the sweep. In the illustrated embodiment, the biasing member 150 maintains the angle of the grain engagement member 102 as great as possible, until the wall engagement member 170 contacts the bin wall 30 as described below. In this orientation, the grain engagement member 102 extends beyond the sweep towards the bin wall 30 and directs the grain toward the sweep for a more complete removal of residual grain located near the bin wall. As shown in FIG. 2, the biasing member can be mounted to its own biasing member bracket 155. Alternatively, the biasing member 150 is attached directly to the distal end of the sweep conveyor.

(16) The Bin wall cleaner 100 can comprise a wall engagement member 170. The wall engagement member 170 contacts the inner surface of the bin wall 30. By directly contacting the inner surface of the bin wall 30, the bin wall cleaner is able to minimize the gap between grain engagement member 102 and the inner surface of the bin wall as the sweep rotates within the bin. The wall engagement member 170 is illustrated as a wheel mounted to the distal end of the grain engagement member 102. Alternatively, the wall engagement member 170 can be a shoe, such as an ultra-high-molecular-weight polyethylene plate that engages the inner surface of the bin wall.

(17) In order to control the pivoting or extending motion, for example, the biasing member 150 is attached at one end to the sweepor a mount securely connected to the sweep. In the illustrated embodiment, one end of the actuator is mounted to the biasing member bracket 155 and the other end of the actuator is attached to the grain engagement member 102. The contracting force of the actuator maintains the wall engagement member 170 in contact with the bin wall 30. As the actuator extends or retracts the actuator rod, the grain engagement member 102 moves relative to the sweep. In an alternative embodiment, the biasing member 150 extends to maintain the grain engagement member 102 pivoted toward the bin wall and has appropriate linkages between the sweep 5 and the grain engagement member 102 to maintain the wall engagement member 170 in contact with the bin wall 30.

(18) The Bin wall cleaner uses one or more blade portions to engage residual grain that would otherwise remain out of the reach of the sweep conveyor. The blade portions 115, 120 can be flat or curved. The blade portions 115, 120 can be made of a solid material, such as a metal or plastic plate. An example of an appropriate plastic plate is an ultra-high-molecular-weight polyethylene, which would provide a low friction and high durability point of contact. The grain engagement member 102 is pivotally mounted to a distal end of the sweep.

(19) The Bin wall cleaner 100 is extendably mounted to the sweep conveyor so that the bin wall cleaner is able to cover the variable distance between the distal end of the sweep and the bin wall. For example, if the bin is out-of-round 4, then the bin wall cleaner could extend for the portion of the bin with the longer radius and retract for the portion of the bin with the shorter radius. The height of the bin wall cleaner can correspond to the height of the sweep.

(20) The Bin wall cleaner 100 is mounted to the distal end 10 of the sweep conveyor 5 at an angle to encourage the residual grain into the path of the sweep conveyor. The angle of the grain engagement member 102 of the bin wall cleaner relative to the sweep is preferably less than 90. In this configuration, the grain engagement member 102 moves with the sweep to push grain into the path of the sweep. This results in a more thorough removal of residual grain from within the grain bin. In the variable angle embodiment, the length of the grain engagement member 102 of the bin wall cleaner 100 is determined by the maximum distance required to be covered by the bin wall cleaner between the sweep 5 and the bin wall 30.

(21) A wall engagement member 170 can be mounted to the distal end of the Bin wall cleaner 100. In the embodiment shown in FIG. 2, the wall engagement member 170 is a wheel, such as a rubber tire. As the sweep conveyor 5 pivots about the cylindrical bin, the wall engagement member 170 rotates about its central vertical axis and resists the biasing force exerted by the biasing member 150.

(22) The wall engagement member 170 maintains contact with the bin wall 30 to assure that the blade portions 115, 120 extend close to the bin wall 30 if the bin is out-of-circle and has a variable radius. The wheel has a radius and is mounted about a vertical axis. As shown in FIG. 2, the wall engagement member 170 is mounted to the Bin wall cleaner 100 at a distance from the distal end 110 of the Bin wall cleaner 100 of about one-half of the radius of the wall engagement member 170. The distal end 110 of the grain engagement member 102 is configured to extend toward the interior surface of the bin wall 30 when the wall engagement member 170 engages the interior surface of the bin wall 30. As such, there is a minimal gap between the distal end 110 of the blade portions 115, 120 and the bin wall 30.

(23) The sweep conveyor may be a standard, existing sweep conveyor or a modified sweep conveyor with an open distal conveyor end. For a bin wall cleaner 100 for use with a standard conveyor, the respective mounts and brackets may be configured to attach to the leading edge of the distal end 110 of the sweep conveyor 5. In such an embodiment, the blade portions 115, 120 may extend outwardly ahead of the sweep conveyor 5. As such, the grain engagement member 102 directs the seed into the opening in the leading wall of the sweep conveyor 5.

(24) The distal longitudinal end 10 of the sweep conveyor 5 can be open such that grain may enter through the open distal conveyor end. In this embodiment, the respective mounts and brackets are configured to attach the Bin wall cleaner 100 to the trailing end of the distal longitudinal end 10 of the sweep conveyor 5, as shown in FIG. 4.

(25) The grain engagement member 102 of the bin wall cleaner 100 can also comprise a fixed or rotating brush (not shown). The brush can extend downwardly from the blades 115, 120. Alternatively, the brush can extend outwardly from the blades 115, 120. Alternatively, the brush could extend downwardly and outwardly. The brush extends the reach of the grain engagement member 102 and facilitates removal of the residual grain from the bin. A rotating brush could be powered by the motion of the sweep, by a linkage to the auger, a linkage to the conveyor roller, a linkage to the wall engagement member 170, or could have an independent power source.

(26) The bin wall cleaner can be integrated with the sweep, or provided as a modular attachment. As a modular attachment, the bin wall cleaner can be directly mounted to the sweep. Alternatively, a bracket can be used to mount the bin wall cleaner to the distal end of generic sweeps. Alternatively, the bin wall cleaner can be integrally formed with the sweep conveyor. As used herein, the sweep conveyor can comprise a belt conveyor, a chain conveyor or an auger mechanism.

(27) In conveyors utilizing a continuous belt conveyor, the belt can utilize a bracket to secure a plurality of spaced-apart cleats to the outer surface of the belt. The bracket is secured to the cleats using one or more fasteners. The fastener can be a plurality of bolts that pass through the bracket and the cleat and are secured by each bolt being securely received by a respective nut. Alternatively, the fasteners could comprise rivets, screws, or pins. Alternatively, a receiver can be integrated into the cleats, where the receiver is configured to allow the bracket to be mounted to the cleat. Alternatively, the bracket can be glued or heat-welded to the cleat. The bracket is secured to the belt using one or more fasteners. As depicted in the images, the fasters can be a plurality of bolts that pass through the bracket and the belt and are secured by each bolt being securely received by a respective nut. Alternatively, the fasteners could comprise rivets, screws, or pins. Alternatively, a receiver can be integrated into the belt that is configured to allow the bracket to be mounted to the belt. Alternatively, the bracket can be glued or heat-welded to the belt. This conveyor belt with detachable cleats can be used in a sweep conveyor, incline conveyor, tube conveyor, or other conveyor applications.
