This invention relates to thrashing machines especially adapted for thrashing all varieties of sorghum grain, such as millo maize, Kafir corn and the like, and the invention has particular reference to a machine of the character specified arranged to co-operate with other units of a complete thrashing and grain handling plant and in which, the principal object is to provide an economical, efficient and thoroughly capable machine for thrashing maize heads especially, which have heretofore been difficult to handle in thrashing.
Another object of the invention resides in the provision of a thrashing unit as specified, which, in order to add to its thoroughness in separating the grain from the straw, is provided with means for causing the maize heads to pass through the machine a number of times, each time subjecting the commodity to a different thrashing process.
Still another object of the invention resides in the provision of means for effecting speedy removalof all refuse from the machine as fast as it accumulates therein, together with means for carrying ofi dust and similar small substance, thus maintaining comparatively clean condition of the machine and insuring more efficient operation.
l/Vith the foregoing objects as paramount, the invention 'has especial reference to its salient features of construction and assembly of parts by which said objects are attained and which will become manifest as the description proceeds, taken in connection with the accompanying drawings, wherein Figure 1 represents a side elevational View of a thrashing unit constructed according to the present invention, with portions broken away to better illustrate its assembly of parts.
Figure 2 is a detail view of the primary thrashing cylinder.
Figure 3 is a detail view of the secondary thrashing cylinder.
Figure 4 is a vertical sectional view on lines l4: of Figure 1, and
Figure 5 is a vertical sectional view on lines 55 of Figure 1.
With reference now in detail to the invention as illustrated in the drawings, its con- Serial No. 264,593.
struction purpose and mode of operation, it may be first mentioned that the thrashing unit as embodied herein, while it may be employed in many ways, it is especially adapted to be used in connection with other elements designed for the purpose of handling sorghum grains, especially millo maize. These mentioned elements, among which are a series of conveyor belts, agitators, reels and cleaners, are arranged to convey the head in its natural state completely through the plant to the final stage or thrashed state, thoroughly separating the grain from the hay, the invention performing this latter step prior to the final cleaning of the grain.
The improved thrashing unit is comprised of the housing 1 preferably formed as shown in Figures 4: and 5 and of the comparative length as in Figure 1. Near the top of the housing, and to one side is situated a cylinder 2 hereinafter referred to as the primary thrashing cylinder and which is comprised of a length of pipe 3, having flights 4: welded or otherwise aifiXed thereto in the spiral manner shown. This pipe is surrounded by a cage 5, comprised of metal bars longitudinally arranged within the housing in parallel relationship and reinforced by annular rings 6, equi-distantly spaced along the length of the cage.
Slightly below and adjacent the opposite. side of the housing 1 is situated what will be referred to herein as the secondary thrashing cylinder 7. With the exception of its being circumferentially smaller, the cylinder 7 is precisely the same in construction as the cyl:, inder 2, but it will be observed that the flights 4; thereon are reversed with respect to those carried by the primary thrashing cylinder 2. This may be clearly seen in Figures 2 and 3. In view of the similarity between the two cylinders 2 and 7, the same characters of reference are used to indicate the parts of the latter cylinder as are used to designate corresponding parts in the primary cylinder 2.
The primary thrashing cylinder 2 is carried upon shaft 8 having protruding ends resting in bearings 9, and on one end of the shaft is mounted a pulley 10, as in Figure la Secondary thrashing cylinder is mounted upon shaft 11 operable in bearing 12 and carrying upon one end a pulley l3.
Immediately below the primary thrashing cylinder 2 is situated a beater 1 L receiving "he commodity from the cylinders2and7 after conveyance therethrough to subject the same to the final action before ejection. This beat or is separated from the upper elements by an inclined partition 15, upon which grain and mali matter, capable of passing between the bars of which the cylinder cages are composed, falls, to be ultimately received by conveyor 16 at the bottom of the housing, and thus conveyed to another element of the plant for cleaning. I
Itlnay be here mentioned that the heads, after passing through primary thrashing cylinder 2, are conveyed into the secondary cylinder T through inclined chute 17, shown in ligure i, and after having traversed the length of this latter cylinder, the commodity is delivered into the beater 14c through chute 18, shown only in Figure 1. Grain and other small matter falling between the bars of the age-5 of cylinders 2 caught upon inclined partitions 19, thence on partition 5 and into tire said flight conveyor 16.
Referring again to the beater 14; this elementis comprised of a series of radially extending arms 20 aiiixed to a longitudinally extending shaft 21, supported by end bearings 22, with intermediate re-inforcing bearings 23. The described combination is operative within a wire mesh cylinder 2 Material en- :ering the mesh cylinder 2% through chute 18 is conveyor. therethrough by the rotating action of the arms 20 and discharged at the opposite end through chute 25, shown in Figurcs 1 and 5, that portion of grain and small matter capable of passing through the walls of the mesh cylinder, falling into the hopper 28 to be received to the conveyor 16 and disposed of. r
The grain, after having been subjected to he action of the several thrashing elements emerges from the unit comparatively clean, however, removal of the dust and small matter escaping the fan 26, situated upon the top of the housing 1, is accomplished in the inal cleaning process by some known type of grain cleaner. The fan 26 however, is very effective in dispensing with the majority of the refuse, and is driven by a small motor 27.
Having described in detail the construction and assembly of the invention, especial reference is made to the operation thereof, under normal conditions in the thrashing, far example, of millo maize heads. These heads, which are very compact and consequently very difficult to handle and thrash are conveyed into the chute 28 entering the primary thrashing cylinder at the top of the housing 1. In order to make the feed uniform, an agitator 29 is arranged within the chute which is driven by a large sprocket wheel 30,
as in Figure 1, having chain connection with a smaller sprocket 31, carried upon a stub shaft 32, which latter has upon its opposite end a pulley 33, driven by some source of power (not shown).
The heads in the natural state thus enter the primary thrashing cylinder 2, and due to the angle and spiral arrangement of the flights it upon the pipe 3, the heads are thrown about and thrashed within the cage 5, during their progressive movementtoward the opposite end of the cage. This action obviously disentegrates the heads permitting the smaller particles and grain to pass through the bars of the cage, and into the conveyor 16.
Having reached the opposite end of the primary cylinder 2, the material failing to pass between'the bars of the cage 5, enters the secondary cylinder 7 through chute 17 whereupon it receives a similar thrashing action, but due to the reverseangle at which the flights 4tare disposed upon the pipe in the latter case, the material is conveyed in the opposite direction, to finally enter the beater casing 24: through chute 18, wherein the ac-v tion upon the material by rotating arms 20 is similar but more severe than that subjected by the two cylinders.
The material after having traversed the length of the beater 14 is now reduced to nothlig more than straw, from which practically all of the grain has been separated. This material or refuse is ejected through the chute 25 while the grain is conveyed to a point of disposal by means of conveyor 16.
In carrying out the operation of the invention in connection with other units forming the hereinbefore mentioned plant, it has been foundeffective to convey the tailings from the thrashing unit to a suitable reel then return the same to the unit for rethrashin More complete results are thus obtained and greater quantities of grain salvaged.
It will be observed in Figures a and 5 that the mesh cylinder 24 is provided with a hinged cover 34, and by raising the same, access may be gained to the beater to make repairs and to removing obstructions by possible entanglement of stalks about the shaft and arms.
Manifestly, the construction shown is capable of considerable modification and such modification as is considered in keeping with the appended claims is also considered within the spirit of the invention.
I claim as my invention:
1. In a thrashing machine, a primary thrashing cylinder, a secondary thrashing cylinder disposed below and to one side of the primary thrashing cylinder, a chute for conducting material from one end of the primary cylinder into the adjacent end of the secondary cylinder, a beater arranged below the primary cylinder in substantial alinement therewith, a chute for conveying material from the opposite end of the secondary cylinder into the adjacent end of the beater, a downwardly inclined partition extending beneath each of the primary and secondary cylinders and over the beater, a hopper beneath the heater to receive material from the latter and from the partition and to also receive material gravitating from the second ary cylinder, an inclined partition below the primary and above the secondary cylinders for directing material from the primary cylinder and from the first named partition into the hopper and a chute leading from the 0pposite end of the beater to conduct material from its inside out of the machine.
2. In a thrashing machine, a primary thrashing cylinder, a secondary thrashing cylinder disposed below and to one side of the primary thrashing cylinder, means to conduct material from one end of the primary cylinder to the adjacent end of the secondary cylinder, a heater below the primary cylinder, means to convey material from the opposite end of the secondary cylinder into the adjacent end of the beater, means between the two cylinders to direct material from the primary cylinder downwardly, a receiver underlying the secondary cylinder to receive material therefrom, means underlying both of the cylinders to direct material therefrom and from said first named directing means downwardly into said receiver, a heater underlying said second directing means, and means to conduct material from the lnside of g the beater to a point outside of the machine.
In testimony whereof I affix my signature.
