This invention relates to a corn sheller.
The chief object of the invention is to provide a corn sheller which will have a capacity at least twice that of present standard corn 5 shellers, and which will operate on clean corn as well as so-called dirty or partially husked ears.
It has been determined that when operating upon clean and dry ears, the capacity of the invention disclosed herein, is substantially three l times that vof the present commercial devices.
This increase in capacity is attributed to the par,- ticular type of shelling rotor which, herein, is disclosed as an open work rotor or shelling reel. One cause for the relatively low capacity of l present commercial corn sheller when cleaning so-called dirty corn, is the sheller jams or clogs due to the inability of the machine to successfully discharge cobs or parts of the cobs, and the husks, and the like, fast eno-ugh to4 conform to the shelling capacity.
The present invention also contemplates the provision of an .adjustable arrangement, whereby the discharge from the sheller is regulated so that cobs will not pass through the sheller without having substantially all the corn grainsshelled therefrom,
Another object of the invention is to separate from the discharged cobs, husks and the like, such shelled corn as may have been carried over or removed from the sheller by reason of the removal action of the means that positively removes the cobs and the husks from the sheller.
In addition to the accomplishment of the aforesaid objects, other objects will appear more fully, as specific features are set forth hereinafter.
The full natureof the invention will be understood from the accompanying drawing and the following specification and claims2 In the drawing, Fig. 1 is a side elevation of one embodiment of the invention in its entirety, parts being broken away to show other parts in section.
Fig. 2 is an end elevation, looking at the discharge end of the machine.
Fig. 3 is a sectional View taken on line 3-3 of Fig. 1, and in the direction of the arrows.
Fig. 4 is asimilar view, taken on line 4 4 of Fig. 1, andin the direction of the arrows.
Fig. 5 is an elevational View of a portion of one of the reel bars.
6 is an end elevational view of a portion ofthe riddle and its mounting.
Fig. 7 is a central sectional view through a portion. of a` modified forml of the invention,
showing another adjustable throat construction.
Fig. 8 is an enlarged central sectional view of the discharge end of the sheller.
Fig. 9 is an enlarged top plan viewof riddle and discharge end of the sheller.
In Figs. 1 to 6, inclusive, Ill indicates the end frames in the form of a pair of bars that support the end castings II and l2. These are secured together in spaced relation by means of the rods I3 and the chamber I4 and these rods lie along said tubular chamber I4 having the inlet portion I5, supplied by a hopper not shown, and an outlet portion or discharge I6. The tubular portion I 4 has its lower portion perforated as at I1.
Herein between the two end plates I2 and I3 are interposed a pair of complementary plates I8 and I9 secured in spaced relation with the space 20 therebetween. Rotatably supported in the two end plates I I and I2, is a shaft 2I which pro-jects beyond said end plates and at one end mounts a suitable driving mechanism in the form of a pulley 22 and at its QlOposite end mounts an eccentric 23 to which reference will be had more fully hereinafter.
suitably secured to the shaft 2l and within the tubular chamber Ill, is a shelling reel. Herein the same includes the end plates 24 having hubs 25 secured as at 26 to said shaft. Extending from end plate 24 to end plate 2t, are a plurality of longitudinally directed bars 26 arranged in spaced relation. Herein four of said bars are provided and suitably secured to the plate portions 24.
Each bar, as shown clearly in Figs. 1 and 5, is provided upon its exterior and interior with inclined lugs 2l and 28 respectively. The lugs on the exterior of each bar are spaced longitudinally and the lugs on the interior of each bar are spaced longitudinally and the spacing is so offset that the lugs successively secured to the bars in longitudinal arrangement are .alternately positioned upon the interior and exterior, as shown. Also preferably, the exterior lugs upon adjacent bars are offset longitudinally of each other and similarly, the interiorly positioned lugs upon adjacent bars are offset longitudinally. The inclination or biasing of the lugs isshown clearly in Figs. 1 and 5. i
The resulting construction constitutesv an open rotor or shelling reel and by reason of this construction, the invention is enabled to not only shell corn lfrom the ears that are interposed between the reel and the tubular body portion I4, but also between the nshaft and the reel and within the reel aswell.
Suitably secured to the shaft 2| is a plate 29 that has mounted upon it blades 30 as at 3|. The aforesaid constitutes an ejector as well as a suction fan and blower. As the unshelled ears, husked or partially husked, or completely husked, are supplied to the chamber Ill through the opening I5, the initial engagement with the reel serves to break up the long cobs into shorter lengths and serves also to separate the husks from the ears. Continued rotation of the ears or movement of the ears longitudinally accompanied by partial rotation of the same from the intake opening I5 to the discharge opening I6, results in the ears, working one upon the other together with the ears working upon the inside of the chamber I4, together with the working of the ears upon the shaft and the reel, all to secure relatively complete shelling of the corn grains from the ear.
The corn that is shelled from the cob falls through the reel and passes out through the openings I'I and into the collecting chamber 32 and discharges therefrom through the spout 33. The husks andl shelled cobs follow through the machine toward the discharge end. They are ejected by the rotor construction including the blades 3U, and through the opening I6. This rotor also serves to create a suction to lift the light chaif and dirt in chamber I4v andY serves to pull it also out of the discharge opening. Thus, a cleaning action also results.
It has been determined that the rate of iiow of the ears through the machine should be varied, according to the condition of the corn to be operated upon. Accordingly, between the plates I8 and I9 and in the space 2U, there is positioned a movable gate 34 pivoted at 35 and provided with a plurality of openings 36. A pin 3'I positioned in the opening is adapted to regulate the controlling position of the movable gate 34. Each of the castings I8 and I9 do not have a large circular opening, but have an enlargement thereon at one portion as at 38.
To provide an impediment or obstruction in the chamber I4, there is provided a pair of bars 39 which are adapted to be detachably positioned by means of pins 40 positioned in openings 4I in the projecting lugs 42 of the plates I3 and I9. If when desired, removal of the pins 4D from said plates and the bars permits the removal of either or both of said bars 39. The two bars 39 straddle the shaft 2|.
As shown in Figs. 1 and 3, there is suitably secured to the plate 24, a pair of arms 43. These' arms terminate adjacent the inside wall of the chamber I4, and are diametrically arranged and provided with angular ends. They serve as agitators, and the like, to insure rotational movement of the cobs, husks, et cetera, that are to pass through the machine and be ejected as waste.
In the present form of the invention, it will be noted that the chamber is divided into two parts, one of which constitutes an ejector and fan chamber and the other of which constitutes primarily a shelling chamber.
Pivotally supported, or otherwise suitably secured, as at 44 is a passage forming construction 45 and the same communicates at one end with the discharge opening IES-see Fig. 4. 'I'he discharge end of the construction 45 terminates above a riddle or shaking screen 46.
The shaking screen 45 ispivotally supported as at 4I upon a member 48. The member 48 in turn is supported by two upwardly directed members 49 and 50 suitably supported as at-5I and 52, respectively, upon one of the frame members I0.
A hook 53 is operatively associated with one of a plurality of the holes 54 in a strap 55 secured as at 56 to the back end of the riddle 46. Thus, the inclination of the riddle having the screen 5l is adjusted by means of the strap 55. When relatively clean corn, having reference to practically all of the husks being removed therefrom, is handled, the inclination of the screen will be at a maximum. When so-called dirty corn is handled, the inclination of the screen will be at a minimum. The reason for this is that with the inclination at a minimum, it will require more agitation to cause the refuse to move along the screen from where it is deposited thereon near the upper end to its discharge at the lower end. The flow rate is thus lessened.
The discharge opening in the member 45 is indicated by the numeral 58, and the latter is covered by a flexible member, such as the blanket 59, the lower end of which more or less rides on the screen surface 51. It may, however, terminate short thereof. 'I'he screen 5'I is moved back and forth at right angles to its longitudinal direction, that is, the direction of iow of the material over the same, by means of the eccentric 23 that is associated with the strap construction 60.
The strap 60 by means of arms 6I has a detachable connection at 62 with the support member 50 through the pin 63. When the arm 6I is associated with the uppermost hole 62, then it will be apparent the maximum reciprocation due to the eccentric is imparted to the riddle; in other words, full stroke is obtained. When associated with the lowermost of the holes 62, it will be apparent that full stroke reciprocation of the eccentricdoes not secure the same stroke or reciprocation of the riddle but such reciprocation will be of a lesser amount, although in the same timed relation.
Below the screen portion 5l of the riddle 46 is another screen of finer mesh, the same being indicated by the numeral 64. This screen has an outlet or discharge 65. Below the rst mentioned, if desired, may be a plate 66. The purpose of the aforesaid is as follows:
The husks and cobs, after being deposited upon the riddle, pass along the same from the point of deposition to the end shown to the extreme left in Fig. 1. In the movement of the refuse along and down the riddle, the corn grains that have been accidentally carried over and from the sheller proper by reason of the ejector or because they have become intermingled or in eluded with the mass of refuse, gradually separate or pass out through the larger mesh in the screen portion 5l and fall upon the smaller mesh screen 64 and discharge as at 65 into the hopper portion 6l that has the same outlet 33. The dirt, and the like, that might normally separate out at this point passes on through the screen 64 and on to the plate 66 and is otherwise disposed of. Thus, the riddle serves not only as a separator but as a cleaner as well.
As shown clearly, in Fig. 1, the right hand portion of the chamber wherein the blower and ejector are mounted, is also perforated at the bottom and the separated corn grains or shelled corn passes through the opening Il into the same hopper or collector 32.
From the foregoing, it will be apparent that if the corn varies from that which is well cleaned and husked to that which is only partially husked, the primary adjustment for regulation of the throat can be made by the bar, or bars, 39. The
extension of the member 34 is so arranged that it is readily accessible, and upon the machine indicating its becoming clogged, elevation of member 34 for a moment or two will immediately clear the machine and permit the attempted obstruction to pass on. As before set forth, the wings or members i3 serve to prevent packing of the material near the discharge end of themachine and keep the obstruction moving.
In Fig. 7 there is illustrated a modified form of the invention and with this form it is to be understood that there is no necessity for the intermediate plates i8 and i9v so that the chamber lll may be substantially continuous. In this form of the invention the end plate rotatably supports shaft |2|. The end plate |24 of the reel structure provided with the bars |26 having the interior and exterior lugs |23 and |21 thereon respectively, also supports the blades |33 of the combination fan and ejector and the same rotates in the chamber l I4 perforated, as before mentioned, as at The dicharge opening is indicated by the numeral i6 and the blades of the rotor serve as an ejector and throw out the husks and the like, from the chamber lit through said opening to the riddle mechanism, such as illustrated fully in Figs. 1 and 2. Projecting inwardly from the plate H24 is a cylinder E39 and the same is stationarily secured so as to rotate with the reel. Obviously, adjacent thereto, the reel bars |25 are not provided with any interior lugs and exteriorly, of course, are not provided with any lugs, because of the fan blades |33.
There is a slight space between the bars |2 and the cylinder |33, and telescopically associated with the latter is a cylinder member |34 which has an open end for such telescopic association, and an opposite tapered end |35 terminating in a hub |36 that is slidably mounted on the shaft l2| and is suitably secured in axially adjusted position on said shaft by the set screw |3l| seatable in any one of the preformed recesses |33 provided in the shaft. As indicated, when the two members |39 and 134 are fully telescoped, the dimension A represents the greatest throat for maximum capacity discharge. When the members are extended to their maximum position, the minimum throat is provided, as indicated, by the dimension Bsee Fig. '7.
It will be perfectly obvious that since the reel is of an open-work character and since the hood l5 in Figs. l and 2 is hinged at 44, the opening Y I3 is readily accessible and the farmer can readily adjust the telescopic member |34 on the shaft in the desired position for most eflicient shelling of the particular type of corn then to be operated upon.
While the member |34 is shown provided with the conical end |35, the same may be of any other desired conformation. This cone, in addition to the throat regulation, prevents the accumulation of cobs, and the like, at the discharge end of the machine and inside the reel. In other words, Iall of the cobs, husks, and the like, that are inside the reel near the discharge end are forced out- Wardly therefrom at said end and are positively ejected by the blades 33. Y
While the invention has been described in great detail in the foregoing specication and several modifications have been set forth and illustrated7 the same is to be considered as illustrative and not restrictive in character. Such modifications as well as others which will readily suggest themselves to persons skillled in this art, are all considered to be within the broad scope of this invention, reference being had to the appended claims.
