Description
THIS INVENTION relate5 to a mixer for mixing grain, hay, feed concentrate and other additives.
~ixing is necessary when more than one ingredient is contained in a feed ration. Efficient mixing becomes essential when the proper ration ~or each beast or bird is to be fed. Each beast needs its proper ration to achieve the weight gain or milk production required. Let us assume that a number of si~ilar beasts (e.g. a line of steers of similar type and age) are being fed. Each beast will n eed a similar ration of feed to achieve a similar weight gain to the remainder. Without mixing, feed containing several ingredients will have poclcets or layers of material. Some b easts will feed on hay, others on grain. Those eating hay will convert less efficiently than those on grain and those on grain run the risk of eating lethal feed. When feed is properly mixed and each beast given equal opportunity, those that are not per-forming in weight gain can be checked and culled for other seasons. Mixers in use heretofore have been of the cyl-inder or cyclone type and have the disadvantage that "dead"
corners exist in the shape of the unit and fine dust collects in these corners, thereb~ restricting the mixin action. Similarly in cyclone mixers fine particles of the feed wasc~rried out by the air and thereforeresulting in a loss of feed besides being a nuisance to workers in tne .'' ' ~
vicinity9 It is the objec-t of this invention to eliMinate dead corners and the like a~d at the s~ne time produce a satisfactory mix.
In one form the invention resides in a mixer comprising a substantially conical mixing chamber supported vertically with its apex lowermos-t, a means for feeding material into the mixing chamber, a tapered auger situated in the mixing chamber, drive means provided at the base of the mixing chamber, the narrowrnost end of -the tapered auger connected to the drive means such that the auger rotates around its own axis and its upper end rolls around the upper periphery of the mixing chamber, the upper end of the tapered auger being provided wi-th a wheel or roller -to allow the tapered auger to fully roll around the upper periphery o~ the mixing chamber and ensure that the tapered a.uger does not contact the walls of the mixing chamber, the wheel or roller being held in con-tact with the upper periphery of ~the mixing ch~nber under the action of the weigh-t o:E the -tapered auger and means of dischargi.ngr the rn~a-teri.al f:rom -the rnixing chamber.
In another forrn the invention resides in a mixer comprising a substan~tially conical mixing chamber, supported vertically wi-th its apex lowermost, a firs~t auger Eor feeding material into the mixing chamber, feed inlet means for delivering materi.al -to the first auger, a tapered auger situated in the mixing chamber, drive means provided at the base of the mixing charnber, linking -the first auger to the -tapered auger, the narrowmost end of the tapered auger connected to the drive means such that the auger rotates around its own axis and its upper ena rolls around -the upper periphery of the mixing chamber~ the upper end of the -tapered auger being provided with a wheel or roller to allow the tapered auger to freely roll around the upper periphery of -the mixing chamber and ensure that the tapered auger does not contact -the walls of the mixing chamber, the wheel or roller being held in contact with the upper periphery of the mixing chamber under the action of the weight of the tapered auger and means for discharging the material from the mixing chamber.
Preferably the upper free end of -the -tapered auger has a wheel or roller posi-tioned -thereon to allow the auger to freely roll arourd the upper periphery of the mixing chamber and ensure that the auger does not contact the walls of the mixing chamber.
The invention will be be-tter unders-tcod by reference to the following description of one specific embodimen-t as shown in -the accompanying drawings wherein:-Fig~ 1 is a side elevation of the mixer;Fig. 2 is a frQn-t elevation;
Fig. 3 is an elevation showin~ the discharge means; and Fig. 4 is a fragmentary view showing the tapered auger in the mixing chamberO
In this embodiment the components of the mixer are mounted on a frame 1 supported on wheels 2. The forward end c~
the frame is provided with means 3 for coupling it to a towing vehicle and a jack 4 for levelling purposes. a drive shaft 5 is provided for a power take off from the towing vehicle to power the augers and hammer mill of the mixer. Material is transferred into a mixing chamber 6 by means of a first auger which is powered through a belt and pulley drive to a pulley on the drive shaft 5. Material to be transferred into the mixing chamber 6 is delivered to the first auger by various means. Grain and similar material is fed through a substantially vertical first inlet 7, hay and like material that requires breaking up is fed through a substantially horizontal second inlet 8 and f~ed concentrates and other additives are fed directly into the auger through inlet 9. The horizontal inlet 8 is closed by a flap door and is provided with a foldable delivery chute 10. The chute is pivoted to allow easy storage and is held in its stored position by a supporting frame 11.
When in use the chute i9 erected into a substantially hor-izontal position and supported by the frame 11. Hay and similar material passes into the horizontal inlet 8 and is broken up into a fine mass by rotating blades in a hammer mill. Any other suitable means may be used to break up the material. The mateFial from the feed inlets is then ' i ,i . I .

transferred into -the mixing chamber 6 by means of the first auger. The substantially conical mixing chamber 6 is mounted in a vertical position with i-ts apex lowermostO
A tapered auger 12 is fit-ted at its narrowmost end -to a universal 13 at the apex of -the conical chamber and mounted for rotation about its own axis and revolution around the upper periphery of the mixing chamber. A wheel or roller 14 is mounted on the free end of ~the tapered auger 12 so that the auger can freely roll around the upper periphery of the mixing chamber and to ensure that the screw of the auger does not con-tact the walls of the mixing chamber.
Because of its tapered shape, the auger 12 has a high centre of gravity. This ensures that the wheel or roller 14 remains in contact with the upper periphery of the mixing chamber under the action of the weight of the tapered auger, even when feed is being mixed, and so eliminates the need to provide means to hold the wheel or roller against -the upper periphery of the mixing chamber. The use of the whleel or roller 14 ~ so dispenses wi-th -the need of having a radial crank arm connected to the upper end of the tapered auger 12 to cause the auger 12 to revolve within the mixing chamber. The -tapered auger 12 i5 powered through the universal 13 and gearing 15 f`rom the drive shaft of the first auger. The rotation and revolu-tion of the tapered auger mixes the feed and ensures -that no fine particles of feed collect in any one sectionO The top of the mixing chamber is closed and provided with an access door 16.
Means to discharge the contents of the mixing chamber may comprise a discharge auger provided within a casing 17, which extends up the side of the mixing chamber. Drive for this auger is taken from the drive of the mixing auger by means of a dog clutch arrangement, which is engaged by a lever. A flap or sliding door 18 closes the outlet from the mixing chamber into the discharge auger casing 17.
When the flap is raised the material can flow from the mixing chamber into the discharge casing and so be carried to the discharge auger outlet. The outlet end of the dis-charge auger has a flexible pipe 20 at-tached to direct the discharging contents into a side discharge auger. This side discharge auger is enclosed in a casing 21 and powered from the drive shaft 5. lhe lower end of this side dis-charge auger is pivotally mounted to the frame for rotation about a substantially horizontal and substantially vertical axis for convenient positioning. A hand operated winch is mounted on the discharge auger casing 21. One end of a wire 22 is wound onto the winch, the other end being fixed to the upper portion of the mixing chamber. The side discharge auger can then be raised or lowered by operation of the winch and pivoted to the desired position for dis-charging of the feed mix.
In use, grain is fed into the vertical feed inlet, hay is fed into the horizontal inlet and through the hammer mill, and feed concentrates and other additives are fed directly .
to the first auger. The feed material is then transferred into the mixing chamber where it is raised by the rotating auger and aliowed to spill back towards the base of the chamber. ~he rotating and revolving motion of the tapered auger ensures that the materials are thoroughly mixed.
The feed can then be discharged as required.
