Description
MULTIPLE VERTICAL AUGER CUTTER MIXER
The present invention relates to a cutler mixer for cutting and mixing rations for cattle and other animals has multiple augers that rotate about vertical axes.
BACKGROUND OF THE INVENTION
Cattle are fed rations that include fodder, silage, and protein supplements. The fodder includes grasses and other plants such as clover and alfalfa. Silage is various green plants that are chopped into small pieces and fermented in a silo. The protein supplement is usually ground or palletized grain.
to Grains that are commonly used include corn, mile, soy beans, barley and oats.
Alfalfa can be processed and used as a protein supplement. Fish meal has also been used as a protein supplement in the past.
The fodder is dried and baled in most cases. The bales are generally large round bales or large rectangular bales. Both large round and rectangular bales is generally weigh between 1,200 and 2,000 pounds. Such bales can be handled and transported economically. Fodder can also be dried and stored in loose slacks.
The fodder is mixed with silage and or with a protein supplement. The fodder is reduced to relatively small pieces either before or during mixing with either silage or a protein supplement. Cows will leave large pieces of coarse fodder and 2o eat only the silage and protein supplement if the fodder is not reduced to a small particle size. Machines for reducing fodder include hammer mill grinders and vertical spindle mixers.

Cows will leave large pieces of coarse fodder and 2o eat only the silage and protein supplement if the fodder is not reduced to a small particle size. Machines for reducing fodder include hammer mill grinders and vertical spindle mixers.
The vertical spindle mixers have a large tub with an open top. One or more vertical spindles arc mounted on the floor of the tub. These spindles include auger flighting and bars with sharp or toothed edges attached to the auger flighting.
Rotating the spindle or spindles reduces the fodder in a large bale to small pieces within a few minutes. Silage and a protein supplement can be mixed with fodder in the mixer. After the feed in the tub is reduced and mixed, a discharge door in a side wall of the tub is opened and the feed is forced through the door by an auger.
A
single spindle mixer discharges the feed through the discharge door and cleans the tab floor rapidly. Large mixers with two or three vertical spindles also discharge the io material rapidly but tend to leave some fodder on the tub floor. Some of the feed tends to be passed from one spindle to another spindle rather than being discharged through the discharge opening after the tub is mostly emptied.

These presently preferred embodiment of the invention is disclosed in the following description and in the accompany drawings, wherein:
Figure 1 is a perspective view of the fodder mixer.
Figure 2 is a vertical sectional view of the tub with three vertical augers and attached cutters.

2o DETAILED DESCRII'TION OF THE PREFERRED i=MBODIMENT
The multiple vertical auger cutler mixer 10 includes a tub 12 with walls 14 and a floor 16. The walls 14 surround the tub 12 and extend upward and outward from the floor 16. The ends 18 and 20 of the tub 12 are arcuate as viewed from above.
The floor 16 of the tub 12 includes a primary floor 22 that forms the lower portion of the tub. A secondary floor 24 is raised up above the primary floor 22. The secondary floor 24 can have a single section, two sections as shown in Figure 2, or more sections.
A primary vertical spindle 26 is journaled on the primary floor 22. The primary spindle 26 has auger flighting 28 that extends radially outward from the spindle. The radially outer edge of the flighting 28 extends radially out to sweep an to envelope that defines a conical area. The flighting 28 at the bottom of primary spindle extends radially outward from the spindle al least twice as far as the flighting al the top of the spindle. Cutters 34 are clamped to the radially outer edge of the flighting 28. Secondary vertical spindles 36 and 38 are journaled on the secondary floor 24. Flighting 43 is attached to the spindles 36 and 38. The flighting 40 on the secondary spindles 36 and 38 is similar to the flighting on the primary spindle 26.
The secondary spindles 36 and 38 are the same height as the primary spindle 26.
The diameter of the portions of the secondary floor 24 swept by the flighting 40 is the same as the diameter of the portions of the primary floor 22 swept by the flighting 28. The flighting 40 can be modified to accommodate the difference between the 2o height of the primary spindle 26 and the height of the secondary spindles 36 and 38 if their vertical heights are not the same.
A generally cylindrical wall portion 42 surrounds the lower portion of the primary spindle 26 and extends from the primary floor 22 to the secondary floor 24, The inside surfaces of the walls 14, including the ends 18 and 20, surround the portions of the secondary floor 24 that do not intersect the wall portion 42.
The leading bottom edge 29 of the auger fighting 28 extends radially outward from the spindle 26 almost to the cylindrical wall 42. The leading bottom edge 29 should sweep substantially the entire primary floor 22 to insure that substantially all fodder is discharged from the primary floor 22 when discharging mixed and cut material from the tub 12. The leading bottom edges 41 of the auger flighting 40 attached to the secondary spindles 36 and 38 extend radially outward from the spindles almost to the end walls 18 and 211. The leading bottom edges 41 should sweep io substantially all fodder from the secondary floor 24 to the primary floor 22 during material discharge.
The secondary vertical spindles 36 and 38 are positioned closer to the primary spindle 26 than the diameter of the area swept by the leading bottom edge 41 of the auger flighting 40. This spacing between the primary spindle 26 and the secondary spindles 36 and 38 minimizes the area of the floor 16 where ground and mixed fodder could possibly lodge during discharge of fodder from the tub 12.
The spacing also results in a portion of the auger flighting 40 moving into posi#ions above the portions of the primary floor 22 swept by the leading bottom edge 29 of the auger flighting 28. By raising the secondary floor 24 and the secondary spindles 36 and 38 2o relative to the primary floor 22, the conical auger flighting 40 can overlap the primary auger flighting 28 on the primary spindle 26 without moving into interference with the primary auger flighting.
The spindles 26, 36 and 38 can be driven mechanically through gear boxes or they can be driven hydraulically by a pump and hydrostatic motors.
The pump is driven by a power take off drive shaft 49 that is connectable to a tractor. As shown in the drawing Figure 2 a box 44 with a hydrostatic motor drives the primary 5 spindle 26. The secondary spindles 36 and 38 are driven by boxes 46 and 48 that include hydrostatic motors. One or more pumps (not shown) supply hydraulic fluid to the hydraulic motors in the boxes 44, 46 and 48.
The spindles 26, 36 and 38 are journaled in the gear boxes 44, 46 and 48 below the primary floor 22 or the secondary floor 24. Due to large bending loads to that can be applied to the spindles 26, 36 and 38 when a 2,000 pound bale is dropped into the tub 12, two vertically spaced apart bearings are employed to journal each spindle.
The cutters 34 on one spindle 26, 36 or 38 are vertically spaced from the cutters on an adjacent spindle. The vertical separation of the cutters 34 on two adjacent spindles 26, 36 or 38 ensures that the cutlers do not contact each other.
Contact between cutters 34 on adjacent spindles 36 or 38 and 26 could also be avoided by providing a timed mechanical drive between the boxes 44, 46 end 48.
Each cutter 34 has a series of teeth 60 that efficiently cut most grass and other fodder into short pieces that are easy for livestock to eat.
2o The vertical auger cutter mixer 10, as shown in Figure 1, is part of a trailer 62. The trailer 62 includes a frame 64 mounted on tires and wheels 66 and 68 by a suspension system. The forward part of the frame 64 is a tongue 70. The forward end of the tongue 70 includes a vertical transverse plate 72. A
coupler (not shown) is bolted to the plate 72. The coupler is normally a bar or bars with a vertical bore that receives a hitch pin and attaches the trailer to the drawbar of a tractor.
The coupler could also be a ring member of a pintel hook hitch or a ball receiver of a ball hitch. The coupler is attached to the plate 72 at a height that is compatible with s the tractor drawbar or other vehicle hi#ch member.
The tub 12 is connected to the trailer 62 by four pins 74, two of which am shown in Figure 1. Each pin 74 includes a strain gauge. The strain gauges are attached to a calculator that displays the weight of fodder, grain protein supplements and any other rations placed in the tub 12, on a display screen 76. The strain io gauges and the display screen 76 permits the operator of the vertical cutter mixer 10 to mix a balanced ration in the tub 12 for the animals to be fed. The tub 12 could also be mounted on the chassis of a truck rather than on a trailer frame. A
third option is to mount the tub 12 on a stationary structure and provide conveyors to carry the cut and mixed rations from the stationary tub 12.
15 An extension lip 78 extends upward from the walls 14 of the tub 12 to increase the capacity of the tub. The extension lip 78 is preferably a rubber belting or other material that will not be damaged by a large hay bale.
A discharge door 80 is provided in a side wall 14 of the tub 12. After the fodder and supplements are cut up and mixed to produce a ration, the discharge 2o door 80 is opened and the rotating auger flighting 28 forces the ration through the discharge opening 82. The secondary spindles 36 and 33 feed the ration toward the primary spindle 26. The primary spindle 26 and the auger flighting 28 force the ration through the discharge opening 82 and substantially clean the primary floor 22.
Very little ration is left in the tub 12.
The ration that is discharged through the discharge opening 82 is deposited upon a discharge conveyor 84. The discharge conveyor 84 can be a chute that directs material moved downward by gravity. The discharge conveyor can also be driven conveyor that forces the ration away from the discharge opening 82. The discharge conveyor 84 shown in Figure 1 is a belt conveyor with an upper run 86 that elevates a ration up and into a feed bunk as the cutter mixer is moving parallel to one side of the feed bunk.
Twenty thousand pounds of ration will feed several hundred cows.
The door 80 may need to be closed as the cutter mixer 10 is moved from one food bunk to another.
The tub 12, shown in Figure 4, has a modified floor 16. The primary horizontal floor 90 is at one and 18 adjacent to the discharge opening 82. The first horizontal secondary floor 92 is in the center of the tub and above the primary horizontal floor 90. The second horizontal secondary floor 94 is at the opposite end of the tub 12 from the primary horizontal floor 90 and is above the first horizontal secondary floor 92. The primary spindle and auger ilighting assembly 96 is identical to the primary spindle 26 and auger flighting 28 described above. The first vertical 20 secondary spindle and auger assembly 98 is substantially identical to the secondary vertical spindles 36 and 38 and the auger flighting 40. The second vertical secondary spindle and auger assembly 100 is substantially identical to the first vertical secondary spindle and auger assembly 98 as described above.
The discharge opening 82 must have a lower edge that is no higher than the primary floor to ensure that the rub 12 is empty and substantially all of the fodder can be discharged. The entire tub 12 is symmetrical and could be reversed on the frame 64. The discharge opening 82 can be in the walls 14 midway between the ends 18 and 20, in a front comer, or in a rear comer. The discharge opening 82 can also be oil the r+ght hand side of the frame 64 or on the left hand side of the frame. There are six clear choices of location for the discharge opening 82.
However, the exact location can vary somewhat in each of the six areas.
During operations of the vertical auger cutter mixer 10, the spindles 26, io 36 and 38 am driven in a direction that forces material upward. As shown in Figure 2, the two secondary spindles 36 and 38 rotate clockwise as viewed from above and the primary spindle 26 is driven in a counter clockwise direction. The auger flighting 28 and 40 can be selected and welded to each spindle 26, 36 and 38 for either clockwise or counter clockwise rotation as desired. The gear boxes 44, 46 and are selected to drive each spindle in the selected direction. The material that is raised by the auger flighting moves from above the spindles 26, 36 and 38 outward toward the walls 14, 18 and 20 of the tub 12 and then downward toward the floor 16.
When the material reaches a position in which it is again urged upward by the auger flighting 28 and 40 the mixing and cutting cycle is repeated. The teeth 60 on the cutters 34 engage fodder that is between the auger alighting 28 and 40 and an adjacent spindles 26, 36 and 38 or between the auger flighting and the walls 14 of the tub 12. The fodder engaged by the cutters 34 is cut or broken into smaller pieces. At the time of engagement by the cutters 34 fodder can be moving upward or downward.
The multiple vertical auger mixer 10 cuts bales of fodder apart, reduces the size of pieces of fodder for easier consumption by livestock and thoroughly mixes the fodder and supplements added to the fodder.
The three spindles 26, 36 and 38 in the tub 12 arc capable of cutting up several hay bales, mixing a selected quantity of ration supplements and producing over 20,000 pounds of ready to feed ration will feed several hundred cattle. Some livestock feeders do not need a cutter mixer 10 with a capacity to feed io several hundred cattle at one time, The capacity can be reduced by eliminating one of the spindles 36 or 38. The primary floor 22 and the raised secondary floor permits two spindles 26 and 36 of a two spindle cutter mixer to be relatively close together and thereby ensure that the primary floor 22 and the secondary floor are fairly clean after discharging fodder through the opening 82.

2o DETAILED DESCRII'TION OF THE PREFERRED i=MBODIMENT
The multiple vertical auger cutler mixer 10 includes a tub 12 with walls 14 and a floor 16. The walls 14 surround the tub 12 and extend upward and outward from the floor 16. The ends 18 and 20 of the tub 12 are arcuate as viewed from above.
The floor 16 of the tub 12 includes a primary floor 22 that forms the lower portion of the tub. A secondary floor 24 is raised up above the primary floor 22. The secondary floor 24 can have a single section, two sections as shown in Figure 2, or more sections.
A primary vertical spindle 26 is journaled on the primary floor 22. The primary spindle 26 has auger flighting 28 that extends radially outward from the spindle. The radially outer edge of the flighting 28 extends radially out to sweep an to envelope that defines a conical area. The flighting 28 at the bottom of primary spindle extends radially outward from the spindle al least twice as far as the flighting al the top of the spindle. Cutters 34 are clamped to the radially outer edge of the flighting 28. Secondary vertical spindles 36 and 38 are journaled on the secondary floor 24. Flighting 43 is attached to the spindles 36 and 38. The flighting 40 on the secondary spindles 36 and 38 is similar to the flighting on the primary spindle 26.
The secondary spindles 36 and 38 are the same height as the primary spindle 26.
The diameter of the portions of the secondary floor 24 swept by the flighting 40 is the same as the diameter of the portions of the primary floor 22 swept by the flighting 28. The flighting 40 can be modified to accommodate the difference between the 2o height of the primary spindle 26 and the height of the secondary spindles 36 and 38 if their vertical heights are not the same.
A generally cylindrical wall portion 42 surrounds the lower portion of the primary spindle 26 and extends from the primary floor 22 to the secondary floor 24, The inside surfaces of the walls 14, including the ends 18 and 20, surround the portions of the secondary floor 24 that do not intersect the wall portion 42.
The leading bottom edge 29 of the auger fighting 28 extends radially outward from the spindle 26 almost to the cylindrical wall 42. The leading bottom edge 29 should sweep substantially the entire primary floor 22 to insure that substantially all fodder is discharged from the primary floor 22 when discharging mixed and cut material from the tub 12. The leading bottom edges 41 of the auger flighting 40 attached to the secondary spindles 36 and 38 extend radially outward from the spindles almost to the end walls 18 and 211. The leading bottom edges 41 should sweep io substantially all fodder from the secondary floor 24 to the primary floor 22 during material discharge.
The secondary vertical spindles 36 and 38 are positioned closer to the primary spindle 26 than the diameter of the area swept by the leading bottom edge 41 of the auger flighting 40. This spacing between the primary spindle 26 and the secondary spindles 36 and 38 minimizes the area of the floor 16 where ground and mixed fodder could possibly lodge during discharge of fodder from the tub 12.
The spacing also results in a portion of the auger flighting 40 moving into posi#ions above the portions of the primary floor 22 swept by the leading bottom edge 29 of the auger flighting 28. By raising the secondary floor 24 and the secondary spindles 36 and 38 2o relative to the primary floor 22, the conical auger flighting 40 can overlap the primary auger flighting 28 on the primary spindle 26 without moving into interference with the primary auger flighting.
The spindles 26, 36 and 38 can be driven mechanically through gear boxes or they can be driven hydraulically by a pump and hydrostatic motors.
The pump is driven by a power take off drive shaft 49 that is connectable to a tractor. As shown in the drawing Figure 2 a box 44 with a hydrostatic motor drives the primary 5 spindle 26. The secondary spindles 36 and 38 are driven by boxes 46 and 48 that include hydrostatic motors. One or more pumps (not shown) supply hydraulic fluid to the hydraulic motors in the boxes 44, 46 and 48.
The spindles 26, 36 and 38 are journaled in the gear boxes 44, 46 and 48 below the primary floor 22 or the secondary floor 24. Due to large bending loads to that can be applied to the spindles 26, 36 and 38 when a 2,000 pound bale is dropped into the tub 12, two vertically spaced apart bearings are employed to journal each spindle.
The cutters 34 on one spindle 26, 36 or 38 are vertically spaced from the cutters on an adjacent spindle. The vertical separation of the cutters 34 on two adjacent spindles 26, 36 or 38 ensures that the cutlers do not contact each other.
Contact between cutters 34 on adjacent spindles 36 or 38 and 26 could also be avoided by providing a timed mechanical drive between the boxes 44, 46 end 48.
Each cutter 34 has a series of teeth 60 that efficiently cut most grass and other fodder into short pieces that are easy for livestock to eat.
2o The vertical auger cutter mixer 10, as shown in Figure 1, is part of a trailer 62. The trailer 62 includes a frame 64 mounted on tires and wheels 66 and 68 by a suspension system. The forward part of the frame 64 is a tongue 70. The forward end of the tongue 70 includes a vertical transverse plate 72. A
coupler (not shown) is bolted to the plate 72. The coupler is normally a bar or bars with a vertical bore that receives a hitch pin and attaches the trailer to the drawbar of a tractor.
The coupler could also be a ring member of a pintel hook hitch or a ball receiver of a ball hitch. The coupler is attached to the plate 72 at a height that is compatible with s the tractor drawbar or other vehicle hi#ch member.
The tub 12 is connected to the trailer 62 by four pins 74, two of which am shown in Figure 1. Each pin 74 includes a strain gauge. The strain gauges are attached to a calculator that displays the weight of fodder, grain protein supplements and any other rations placed in the tub 12, on a display screen 76. The strain io gauges and the display screen 76 permits the operator of the vertical cutter mixer 10 to mix a balanced ration in the tub 12 for the animals to be fed. The tub 12 could also be mounted on the chassis of a truck rather than on a trailer frame. A
third option is to mount the tub 12 on a stationary structure and provide conveyors to carry the cut and mixed rations from the stationary tub 12.
15 An extension lip 78 extends upward from the walls 14 of the tub 12 to increase the capacity of the tub. The extension lip 78 is preferably a rubber belting or other material that will not be damaged by a large hay bale.
A discharge door 80 is provided in a side wall 14 of the tub 12. After the fodder and supplements are cut up and mixed to produce a ration, the discharge 2o door 80 is opened and the rotating auger flighting 28 forces the ration through the discharge opening 82. The secondary spindles 36 and 33 feed the ration toward the primary spindle 26. The primary spindle 26 and the auger flighting 28 force the ration through the discharge opening 82 and substantially clean the primary floor 22.
Very little ration is left in the tub 12.
The ration that is discharged through the discharge opening 82 is deposited upon a discharge conveyor 84. The discharge conveyor 84 can be a chute that directs material moved downward by gravity. The discharge conveyor can also be driven conveyor that forces the ration away from the discharge opening 82. The discharge conveyor 84 shown in Figure 1 is a belt conveyor with an upper run 86 that elevates a ration up and into a feed bunk as the cutter mixer is moving parallel to one side of the feed bunk.
Twenty thousand pounds of ration will feed several hundred cows.
The door 80 may need to be closed as the cutter mixer 10 is moved from one food bunk to another.
The tub 12, shown in Figure 4, has a modified floor 16. The primary horizontal floor 90 is at one and 18 adjacent to the discharge opening 82. The first horizontal secondary floor 92 is in the center of the tub and above the primary horizontal floor 90. The second horizontal secondary floor 94 is at the opposite end of the tub 12 from the primary horizontal floor 90 and is above the first horizontal secondary floor 92. The primary spindle and auger ilighting assembly 96 is identical to the primary spindle 26 and auger flighting 28 described above. The first vertical 20 secondary spindle and auger assembly 98 is substantially identical to the secondary vertical spindles 36 and 38 and the auger flighting 40. The second vertical secondary spindle and auger assembly 100 is substantially identical to the first vertical secondary spindle and auger assembly 98 as described above.
The discharge opening 82 must have a lower edge that is no higher than the primary floor to ensure that the rub 12 is empty and substantially all of the fodder can be discharged. The entire tub 12 is symmetrical and could be reversed on the frame 64. The discharge opening 82 can be in the walls 14 midway between the ends 18 and 20, in a front comer, or in a rear comer. The discharge opening 82 can also be oil the r+ght hand side of the frame 64 or on the left hand side of the frame. There are six clear choices of location for the discharge opening 82.
However, the exact location can vary somewhat in each of the six areas.
During operations of the vertical auger cutter mixer 10, the spindles 26, io 36 and 38 am driven in a direction that forces material upward. As shown in Figure 2, the two secondary spindles 36 and 38 rotate clockwise as viewed from above and the primary spindle 26 is driven in a counter clockwise direction. The auger flighting 28 and 40 can be selected and welded to each spindle 26, 36 and 38 for either clockwise or counter clockwise rotation as desired. The gear boxes 44, 46 and are selected to drive each spindle in the selected direction. The material that is raised by the auger flighting moves from above the spindles 26, 36 and 38 outward toward the walls 14, 18 and 20 of the tub 12 and then downward toward the floor 16.
When the material reaches a position in which it is again urged upward by the auger flighting 28 and 40 the mixing and cutting cycle is repeated. The teeth 60 on the cutters 34 engage fodder that is between the auger alighting 28 and 40 and an adjacent spindles 26, 36 and 38 or between the auger flighting and the walls 14 of the tub 12. The fodder engaged by the cutters 34 is cut or broken into smaller pieces. At the time of engagement by the cutters 34 fodder can be moving upward or downward.
The multiple vertical auger mixer 10 cuts bales of fodder apart, reduces the size of pieces of fodder for easier consumption by livestock and thoroughly mixes the fodder and supplements added to the fodder.
The three spindles 26, 36 and 38 in the tub 12 arc capable of cutting up several hay bales, mixing a selected quantity of ration supplements and producing over 20,000 pounds of ready to feed ration will feed several hundred cattle. Some livestock feeders do not need a cutter mixer 10 with a capacity to feed io several hundred cattle at one time, The capacity can be reduced by eliminating one of the spindles 36 or 38. The primary floor 22 and the raised secondary floor permits two spindles 26 and 36 of a two spindle cutter mixer to be relatively close together and thereby ensure that the primary floor 22 and the secondary floor are fairly clean after discharging fodder through the opening 82.
