Description
- This application is a continuation of co-pending U.S. Ser. No. 09/811,309 filed Mar. 16, 2001 which is a continuation-in-part of co-pending U.S. Ser. No. application Ser. No. 09/590,347 filed Jun. 8, 2000 which is a continuation in part of co-pending application U.S. Ser. No. 09/562,167 filed May 2, 2000. All the subject matter of the aforementioned applications are incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a mixer apparatus for mixing livestock feed. More specifically, the present invention relates to a vertical auger mixer having at least one auger.
- 2. Information Disclosure Statement.
- Cattle farming requires the mixing of various livestock feeds for subsequent distribution. Additionally, mixers can be used for mixing other materials such as composts and the like. Sometimes such mixing of feeds includes depositing at least one bale of hay into a mixer container together with other additives. The materials within the container are mixed by means of at least one auger which rotates within the container so that an intimate mixing of the contents of the container is obtained. Although many mixers employ a pair of horizontal interacting augers extending longitudinally along the container, several mixers have been proposed in which the auger or augers are disposed vertically.
- In the prior art mixers of the vertical auger type, such mixers sometimes include a pair of augers in which the rotational axes of the augers are disposed spaced and approximately parallel relative to each other. Furthermore, each of such augers is driven by a separate drive which supplies rotary motion to each of the augers from below.
- Also, some mixers have a single auger. However, the aforementioned twin auger mixers suffer from the following drawbacks. First, the provision of two 90 degree drives and associated planetary reduction gearboxes is extremely expensive and involves the manufacture of many parts. Second, access to such gearboxes requires removal of the gearboxes from underneath the mixer and then disassembly of such gearboxes. Third, the augers include continuous flighting which provides less agitation of the feed. Fourth, at the end of a mixing operation, an operator will usually find it necessary to rev up the power take off in an attempt to throw materials centrifugally away from the augers so that the augers are cleaned. Fifth, when weighing materials to be mixed, inaccurate measurements are made when the mixer is on uneven ground. Such inaccuracies are caused mainly because when a load cell is disposed at the hitch of a drawbar, the reading reflects a vector rather than a vertical weight when the mixer is tilted. Most of the aforementioned drawbacks are also applicable to single auger mixers and the cost of providing a planetary gearbox and other parts is considerable.
- The present invention provides a vertical auger mixer apparatus which overcomes all of the aforementioned problems associated with the prior art arrangements.
- Therefore, it is a primary feature of the present invention to provide a mixer apparatus which overcomes the aforementioned problems associated with the prior art vertical auger mixers and which provides a significant contribution to the art of mixing animal feeds and the like.
- Another feature of the present invention is the provision of a mixer apparatus that reduces the cost of manufacture thereof.
- A further feature of the present invention is the provision of a mixer apparatus that permits vertical removal of the auger or augers together with the associated driven gear.
- Another feature of the present invention is the provision of a mixer apparatus that enhances the mixing of the livestock feed.
- Yet another feature of the present invention is the provision of a mixer apparatus that assists in the cleaning of the augers after a mixing operation.
- Another feature of the present invention is the provision of a mixer apparatus which includes a more accurate means for weighing the livestock feed.
- Throughout the description of the various embodiments of the present invention, the term auger or augers is to be understood to include paddle arrangements and that the flighting includes screw and/or helix type arrangements which may be continuous or non-continuous and would include segmented augers. Also, throughout the description and claims of the present invention, the term animal feeds is to be understood as including composts and other materials that require mixing.

Adrive 148 f extends around thefirst drive sprocket 112 f and the final drivenwheel 28 f so that when thefirst drive sprocket 112 f is rotated, thedrive 148 f rotates the final drivenwheel 28 f. Also, a further final drivenwheel 140 f is a further driven sprocket wheel. Afurther drive 150 extends around thesecond drive sprocket 146 and the further final drivenwheel 140 f so that when thesecond drive sprocket 146 is rotated, thefurther drive 150 rotates the further final drivenwheel 140 f. Thedrive 148 f is a first roller chain drive and thefurther drive 150 is a second roller chain drive. - Those skilled in the art will appreciate that the arrangement shown in FIGS. 11 and 12 could include replacing the driven and drive sprockets with driven and drive pulleys with the drive roller chain being replaced with a belt drive. Similarly, the further driven and further drive sprockets and further roller chain drive could be replaced by a further driven pulley, further drive pulley and further drive belt respectively.
- FIG. 13 is a view taken from beneath the
mixer apparatus 10 shown in FIG. 3. As shown in FIG. 13, a plurality ofwheels 36′ and 38′ shown in FIG. 1a includes thefirst wheel 36′ and thesecond wheel 38′ disposed spaced and coaxial relative to thefirst wheel 36′. Afirst load cell 152 is disposed between thefirst wheel 36′ and theframe 34′ and asecond load cell 154 is disposed between thesecond wheel 38′ and theframe 34′ as shown in FIG. 13. - FIG. 14 is an enlarged perspective view of the
hitch bar 40 as shown in FIG. 1. As shown in FIG. 14, thehitch bar 40 is connected to theframe 34 and is disposed remote from thewheels third load cell 156 has a first and asecond end first end 158 of thethird load cell 156 being secured to theframe 34. Aclevis 162 is attached to thesecond end 160 of thethird load cell 156, theclevis 162 being rotatable as indicated by thearrow 164, about alongitudinal axis 166 of thethird load cell 156. The arrangement is such that during a weighing operation which is dependent on measurements from the first, second andthird load cells rotatable clevis 162 adjusts to a difference in an inclination of themixer apparatus 10 and a tractor (not shown) so that side pressures and inaccuracies in measurements from thethird load cell 156 is decreased. - In operation of the
mixer apparatus 10′ according to the present invention as shown in FIG. 2, thecover 56 is unbolted from thefloor 50 and theauger 24′ and final drivenwheel 28′ are removed upwardly as a single unit so that immediate inspection and servicing of the final drivenwheel 28′ anddrive wheel 112′ is permitted. Also, reassembly of theunit 32 which includes theauger 24′ and final drivenwheel 28′ is a simple operation in which the unit is lowered through theenclosure 22′ followed by refastening thecover 56 to thefloor 50. - The operation of the twin auger mixer shown in FIG. 1 is similar to the operation of the single auger mixer except in that the
common drive wheel 112 is able to drive bothaugers augers drive wheel 112. - The present invention provides a vertical auger mixer having a number of unique features which reduce the cost of production thereof and provide a mixer which permits easy access for inspecting and servicing the drive gears thereof
