Abstract

Conventional mixing devices impart compaction to the bulk material that can be overly dense or does not allow ideal air within the mixed bulk material. Further, they require overly long mix times and/or high amounts of power consumption to achieve a desired level of variance. Inclinable mixers are provided herein that address these issues. The inclined mixer comprises a mixing chamber which comprises a longitudinal trough defined by side walls, a discharge opening positional substantially in the bottom of the chamber toward a back end, and a front wall spanning the front end of the trough. The mixer also comprises an auger situated longitudinally in the trough for mixing bulk material, and a driving device for rotating the auger when a driving force is applied, wherein the mixing chamber is inclined at least during mixing such that the back end is raised relative the front end.

Claims

We Claim:

1. An inclinable mixer for mixing bulk al, the inclined mixer comprising: a mixing chamber comprising: 5 a longitudinal trough defined by a first and second side wall oppositely d, the trough having a front end te a back end, a discharge opening positioned substantially toward the back end of the mixing chamber, a front wall spanning the front end of the trough, 10 front legs for supporting the front end of the mixing chamber, back legs for supporting the back end of the mixing chamber, an auger situated longitudinally in the trough for mixing bulk al, and a driving device for rotating the auger when a driving force is applied, wherein the mixing chamber is inclined at least during mixing such that the back end is raised 15 relative the front end, and wherein the front legs are adapted to raise and lower the front end ve to the back end of the mixing chamber to change the degree of incline of the mixing chamber.

2. The inclinable mixer of claim 1, wherein the back legs are positioned inward from the back end 20 such that the discharge opening is closer to the back end than the back legs allowing the discharge g to output material mixed therein without interference from the back legs.

3. The inclinable mixer of claim 1, wherein the front legs are adapted to raise and lower the front end of the mixer to move the mixer from an inclined on, for mixing bulk material to a substantially 25 level position for unloading of the mixer chamber.

4. The inclinable mixer of any one of claims 1 to 3, wherein the front legs are telescoping legs.

5. The inclinable mixer of any one of claims 1 to 4, wherein the front legs are scissor legs.

6. The inclinable mixer of claim 5, wherein the r legs are hydraulically operated.

7. The inclinable mixer of any one of claims 1 to 6, wherein the front and back legs are operable to lift the mixer into an unloading position at a height sufficient to allow a delivery vehicle to pass beneath 35 the discharge opening.

8. The inclinable mixer of any one of claims 1 to 7, further comprising: a front baffle positioned at the front end of the mixing chamber and transverse and above the auger for g bulk material s the auger. 5

9. The inclinable mixer of any one of claims 1 to 8, further comprising: a front right baffle positioned at the front end of the mixing chamber between the auger and the second side wall for guiding bulk material towards the auger.

10. The inclinable mixer of any one of claims 1 to 9, r comprising: 10 a front left baffle positioned at the front end of the mixer r n the auger and the first side wall for guiding bulk material towards the auger.

11. The inclinable mixer of any one of claims 1 to 10, wherein the trough is a V-shaped trough, a U- shaped trough or a tube.

12. The inclinable mixer of any one of claims 1 to 11, wherein the first and second side walls of the trough are substantially symmetrical.

13. The inclinable mixer of any one of claims 1 to 11, wherein the first and second side walls of the 20 trough are substantially asymmetrical with one of the two side walls situated at a steeper angle relative the other side wall.

14. The inclinable mixer of any one of claims 1 to 13, wherein the mixing r is for inclination to above 20 degrees during mixing.

15. The inclinable mixer of any one of claims 1 to 13, wherein the mixing r is for inclination to above 40 degrees during mixing.

16. The inclinable mixer of any one of claims 1 to 13, wherein the mixing chamber is for inclination 30 to or above 45 degrees during mixing.

17. The inclinable mixer of any one of claims 1 to 16, wherein the mixing chamber further comprises: a second longitudinal trough defined by a third and fourth side wall oppositely opposed, the second trough having a front end opposite a back end, a discharge opening positioned substantially toward the back end of the second trough, a front wall spanning the front end of the second trough, the mixer further comprising a second auger situated longitudinally in the second trough for 5 mixing bulk material.

18. The inclinable mixer of claim 17, wherein the first and second augers are adapted to rotate in opposite directions during mixing. 10

19. The inclinable mixer of claim 17 or 18, wherein the second and third side walls are connected ly or indirectly at their top edges and are sufficiently short to allow for bulk material mixing in the chamber to pass over their top edges.

20. The able mixer of any one of claims 1 to 19, wherein the driving device is hydraulically 15 powered.

21. The inclinable mixer of claim 20, wherein the front legs are hydraulically powered and the front legs and driving device are operated by the same hydraulic system. 20

22. The able mixer of claim 21, wherein the front legs and driving device are powered by the same lic drive source.

23. The inclinable mixer of any one of claims 1 to 22, wherein the discharge g of the first trough and/or second trough is positioned in substantially the bottom of the trough toward the back end 25 of the mixing chamber.

24. The inclinable mixer of any one of claims 1 to 22, wherein the discharge opening of the first trough and/or second trough is positioned in the side of the trough toward the back end of the mixing chamber.

25. The inclinable mixer of any one of claims 1 to 24, wherein the mixer further comprises a trough door situated over the rge opening of the first trough and/or second trough and movable between a closed position wherein the trough door covers the discharge opening of the first trough and/or second trough and an opened positioned wherein the trough door uncovered the discharge opening of the first 35 trough and/or second trough and allows output of material from the chamber.

26. The inclinable mixer of any one of claims 1 to 25, further comprising one of more additional augers, each associated with one more additional troughs.

27. The inclinable mixer of any one of claims 1 to 26, n a front section of the auger has a 5 higher density of flights than a back section of the auger.

28. The inclinable mixer of any one of claims 1 to 27, wherein the auger is a multiple ribbon auger.

29. The inclinable mixer of any one of claims 1 to 28, wherein the auger is a ribbon auger.

30. The inclinable mixer of claim 29, wherein a front face of the ribbon auger is covered with a plastic/polymer ng or stainless steel or wear surface.
