Abstract

At least one example embodiment relates to an apparatus including a dosing tube and a plate. The dosing tube is configured to receive an auger. The dosing tube includes a cylindrical sidewall extending from a first end to a second end opposite the first end. The dosing tube defines an opening in the cylindrical sidewall. The plate is coupled to the second end of the dosing tube. The dosing tube is configured to rotate with respect to the plate. In at least one example embodiment, the apparatus further includes an auger configured to rotate and move a material from the second end to the first end of the dosing tube.

First claim

I claim:

1. An apparatus comprising:
a hopper including,
a hopper wall;

a dosing tube configured to receive an auger, the dosing tube including a cylindrical sidewall extending from a first end to a second end opposite the first end, the dosing tube defining a single opening in the cylindrical sidewall, the cylindrical sidewall including a first indicia, the auger configured to move a material toward the single opening, the single opening along less than an entire length of the dosing tube; and
a plate coupled to the second end of the dosing tube and the hopper wall, the plate including,
a second indicia cooperating with the first indicia to indicate a degree of rotation of the dosing tube, the dosing tube configured to rotate to a desired angular position with respect to the plate, the dosing tube configured to be fixed at the desired angular position.

2. The apparatus of claim 1 , wherein the dosing tube is configured to freely rotate with respect to the plate.

3. The apparatus of claim 1 , wherein the dosing tube is configured to rotate in an increment ranging from 1° to 10°.

4. The apparatus of claim 3 , wherein the increment is 2°.

5. The apparatus of claim 3 , wherein the increment is 5°.

6. The apparatus of claim 1 , wherein the first end of the dosing tube is closed.

7. The apparatus of claim 1 , wherein the single opening is closer to the first end of the dosing tube than the second end of the dosing tube.

8. The apparatus of claim 1 , wherein the second end of the dosing tube is open.

9. The apparatus of claim 1 , wherein the single opening is a circular opening.

10. The apparatus of claim 1 , wherein
the first end of the dosing tube is closed,
the second end of the dosing tube is open, configured to receive the auger, and configured to receive the material from the hopper,
the single opening is circular, and
the single opening is closer to the first end of the dosing tube than the second end of the dosing tube.

11. An apparatus comprising:
a hopper including,
a hopper wall;

a dosing tube extending from a first end to a second end opposite the first end, the dosing tube defining a chamber and a single opening in a side of the dosing tube, the single opening along less than an entire length of the dosing tube, the dosing tube including a first indicia;
a plate coupled to the second end of the dosing tube, and the hopper wall, the plate including,
a second indicia cooperating with the first indicia to indicate a degree of rotation of the dosing tube, the dosing tube configured to rotate to a desired angular position with respect to the plate, the dosing tube configured to be fixed at the desired angular position; and

an auger within the chamber of the dosing tube, the auger configured to rotate and move a material from the second end to the first end of the dosing tube.

12. The apparatus of claim 11 , further comprising:
a motor operatively coupled to the auger and configured to rotate the auger within the dosing tube.

13. The apparatus of claim 11 , wherein the dosing tube is configured to freely rotate with respect to the plate.

14. The apparatus of claim 11 , wherein the dosing tube is configured to rotate in an increment ranging from 1° to 10°.

15. A method comprising:
Rotating a dosing tube to a desired angular position with respect to a plate coupled to an end of the dosing tube and a hopper wall of a hopper, the dosing tube including a first indicia, the plate including a second indicia cooperating with the first indicia to indicate a degree of rotation of the dosing tube;
fixing the dosing tube at the desired angular position;
rotating an auger within the dosing tube such that a material moves through the dosing tube toward a single opening in the dosing tube, the single opening along less than an entire length of the dosing tube; and
continuing rotating the auger such that a desired amount of the material is discharged through the single opening in the dosing tube.

16. The method of claim 15 , wherein the rotating the dosing tube includes rotating the dosing tube in an increment ranging from 1° to 10°.

17. The method of claim 16 , wherein the increment is 2°.

18. The method of claim 16 , wherein the increment is 5°.

19. The method of claim 15 , wherein the rotating the auger includes rotating the auger at least 360°.

20. The method of claim 15 , wherein the rotating the auger includes activating a motor coupled to the auger.
