Abstract

Disclosed is a vehicle carrying a grinder-mixer providing a low bin profile and improved mixing through the use of complementing horizontal and vertical circulatory paths of the ground feed, which is produced by a pair of cooperating parallel auger conveyors extending in a horizontal plane along the bottom of the mixing bin in side by side relationship and rotating so as to move the feed in opposite directions, each feeding the other, in cooperation with a pair of vertical cooperating augers spaced axially of the horizontal augers and moving and mixing the ground feed along a circulatory path in vertical planes, the said horizontal and vertical circulatory paths intersecting to thereby greatly increase the mixing action. One of the horizontal augers is connected to a discharging system and is reversible to cooperate with the latter to empty the bin.

2. The structure defined in claim 1 wherein said first mixing mechanism is comprised of a pair of parallel horizontal augers located directly below and immediately adjacent to said second mixing mechanism and driven so as to move the feed in opposite directions.

3. The structure defined in claim 2 wherein said second mixing mechanism is comprised of a pair of cooperating vertically extending augers spaced axially of and between the axes of said horizontal augers.

4. The structure defined in claim 3 and a divider mounted within said bin between the lower end portions of said vertically extending augers and above said first mechanism and effectively dividing said bin into a pair of adjacent communicating bins between which such ground feed is interchanged by said mixing mechanisms.

5. The structure defined in claim 3 wherein said vertically extending augers are disposed within the vertical confines of said horizontal augers.

6. The structure defined in claims 3 wherein said bin is generally rectangular in horizontal cross-sectional shape and said mixing bin has a bottom across which said horizontal augers extend, the width of said bottom measured transversely of said horizontal augers being at least one-third of the dimensions of said bin when measured in the same direction whereby said bin has maximum volume and the grinder-mixer may have a low profile.

7. The structure defined in claim 2 wherein one of said horizontally extending augers is reversible in its direction of rotation and is connected to said unloading mechanism in ground-feed delivering relation when so reversed.

8. The structure defined in claim 1 wherein said second mixing mechanism is comprised of a pair of cooperating vertically extending augers spaced longitudinally of and within the vertical confines of said first mixing mechanism.

9. A ground-feed mixer comprising:

(a) a bin constructed and arranged to receive ground-feed therein;

(b) first power-driven feed-mixing mechanism connected with said bin and constructed and arranged to engage, move and mix such ground-feed in a circulatory path in a generally horizontal plane along the bottom of said bin; and

(c) second power driven feed-mixing mechanism mounted within said bin, in ground-feed-receiving relation with said first mixing mechanism, and being constructed and arranged directly above and in close proximity to said first feed mixing mechanism to cooperatively move, mix and cross-mix such ground-feed from that horizontal plane, in a circulatory path in a generally vertical plane to the upper portions of said bin;

(d) said horizontal and vertical paths of circulation of ground feed intersecting whereby the feed moved by said mechanisms are cross-mixed.

10. The structure defined in claim 9 wherein said first power-driven feed-mixing mechanism is comprised of a pair of parallel interacting augers mounted along the lower portions of said bin and constructed and arranged to drive the ground feed in opposite directions to cooperatively mix the feed therein and move the same along a circulatory horizontal path.

11. The structure defined in claim 10 wherein at least one of said augers is constructed and arranged to be selectively reversibly driven for discharge of the ground-feed from the bin.

12. The structure defined in claim 10 wherein the augers of said first feed-mixing mechanism are each mounted in feed-receiving and discharging relation to the other.

13. The structure defined in claim 9 wherein said first feed-mixing mechanism is constructed and arranged to move such feed along a circulatory path which is generally elliptical in shape.

14. The structure defined in claim 9 wherein said second power-driven feed-mixing mechanism is comprised of a pair of spaced interacting vertically extending augers mounted in said bin directly above said first mechanism and extending upwardly from said first feed-mixing mechanism in feed-receiving relation thereto and constructed and arranged to be driven to cooperatively move, mix and cross-mix the feed in the bin upwardly and outwardly along a circulatory path in a vertical plane, which path intersects said horizontal path of said first mixing mechanism.

15. The structure defined in claim 14 wherein said pair of augers are spaced longitudinally of said first power-driven feed-mixing mechanism.

16. The structure defined in claim 14, and a divider mounted within said bin above said first mechanism and between the lower end portions of said augers.

17. The structure defined in claim 14 and a plurality of chains carried by the individual flights of said vertically extending augers and cooperatively stirring and mixing the ground feed therearound as said augers are rotated.
