Abstract

The present disclosure is directed to an agitating system having a sub-hopper configured to receive particulate material, an agitator disposed within the sub-hopper and configured to promote movement of the particulate material through the sub-hopper, and a deflector configured to block a portion of the particulate material from exerting a force onto the agitator as the particulate material flows through the sub-hopper. The deflector is positioned such that the agitator extends beyond a first distal edge and a second distal edge of the deflector along a lateral axis.

First claim

1 . An agitating system, comprising:
a sub-hopper configured to receive particulate material; an agitator disposed within the sub-hopper, wherein the agitator is configured to promote movement of the particulate material through the sub-hopper; and a deflector configured to block a portion of the particulate material from exerting a force onto the agitator as the particulate material flows through the sub-hopper, wherein the deflector is positioned such that the agitator extends beyond a first distal edge and a second distal edge of the deflector along a lateral axis.

2 . The agitating system of claim 1 , wherein the deflector has a first leg and a second leg disposed at an angle with respect to one another to form a triangular shape.

3 . The agitating system of claim 2 , wherein a first length of the first leg is approximately equal to a second length of the second leg.

4 . The agitating system of claim 1 , wherein the deflector is positioned above the agitator, and a top of the agitator extends beyond the first distal edge and the second distal edge of the deflector along a vertical axis.

5 . The agitating system of claim 1 , wherein the deflector is formed from metal, composite, or both.

6 . The agitating system of claim 1 , wherein the agitator comprises a shaft extending along a longitudinal axis, and the deflector is substantially aligned with the shaft along the lateral axis.

7 . The agitating system of claim 6 , wherein the deflector extends along a substantial portion of a length of the shaft along the longitudinal axis.

8 . An agitating system of an agricultural system, comprising:
an agitator, comprising:
a shaft extending along a length of the agitator; and
an agitator coil coupled to the shaft, wherein the agitator coil is wrapped around the shaft along the length of the agitator, and the agitator is configured to promote movement of particulate material in response to rotation of the agitator coil about the shaft; and
a deflector positioned adjacent to the agitator, wherein the deflector extends along the length of the agitator and is configured to block a portion of particulate material from flowing directly onto the agitator.

9 . The agitating system of claim 8 , wherein the deflector comprises a first leg and a second leg disposed at an angle with respect to one another to form a triangular configuration.

10 . The agitating system of claim 9 , wherein a first distal edge of the first leg and a second distal edge of the second leg is disposed between 5 mm and 10 mm below a top of the agitator coil along a vertical axis.

11 . The agitating system of claim 10 , wherein the first distal edge of the first leg and the second distal edge of the second leg are separated from one another by a distance along a lateral axis, wherein the distance is between 70 mm and 100 mm.

12 . The agitating system of claim 9 , wherein the angle between the first leg and the second leg is between 60 degrees and 120 degrees.

13 . The agitating system of claim 8 , wherein the deflector is positioned above the agitator along a vertical axis.

14 . The agitating system of claim 8 , wherein a deflector width of the deflector does not extend beyond an agitator width of the agitator along a lateral axis.

15 . The agitating system of claim 8 , wherein the deflector is substantially symmetrical about a rotational axis of the shaft.

16 . An agricultural system, comprising:
a storage tank configured to hold particulate material; an agitator configured to promote movement of the particulate material through the storage tank; and a deflector configured to block a portion of the particulate material from flowing directly onto the agitator, wherein the deflector comprises a first leg and a second leg disposed at an angle with respect to one another to form a triangular shape, and the deflector is positioned adjacent to the agitator such that a top of the agitator extends past a first distal edge of the first leg and past a second distal edge of the second leg between the first leg and the second leg along a vertical axis.

17 . The agricultural system of claim 16 , comprising a bracket coupled to a wall of the storage tank and to the deflector, wherein the bracket is configured to support the deflector.

18 . The agricultural system of claim 16 , wherein a deflector width of the deflector does not extend past an agitator width of the agitator along a lateral axis.

19 . The agricultural system of claim 16 , comprising a metering system coupled to the storage tank, wherein the metering system comprises an inlet configured to receive particulate material, the inlet has a first width, the deflector is positioned such that a gap is formed between the deflector and a wall of the storage tank, and the gap has a second width that is greater than the first width.

20 . The agricultural system of claim 16 , wherein the agitator is positioned below the deflector with respect to a vertical axis.
