GRAIN SEED CLEANER.
State of lndianmhave made a certain new and useful Invention in Grain and Seed Cleaners, of which the following is a specification. p p
The invention has relation to grain and seed cleaners havlng for an Object the provision of an improved device of this charcurrents.
acter, including more efficient means for separating the light refuse matter from the material to be cleaned.
The invention consists in the novel construction and combination of parts, as hereinafter set forth.
In the accompanying drawings illustrating the invention, Figure 1 is a side view of the invention; Figure 2 is an end view of the same, and Figure 3 is a central vertical section of the same.
In these drawings the numeral 1 designates a hopper adapted to discharge the grain or other material upon a vibratory chaff screen 2 in the usual man ner, said screen having a, screen board 2*. thereunder. Beneath the discharge end of the screen 2 is located a chute 3, provided with converging deflector walls of unequal length, both imperforate and the longer and outer wall being adapted to receive material discharged from said screen and screen board to check its fall. The side walls 6 of said chute are extended to form the side Walls of an air duct 7, the latter-being also provided with an imperforate upper wall 8 and an imperforate lower single arched humped wall 9, said. hump resulting in said duct having a contracted middle portion and flaring end portions. One of the said flaring end portions has a lower wall,bei ng a part of the wall 9, inclined oppositely to and receiving material discharged from said longer wall of said chute and forming therewith a second and lower chute 10. The downwardly directed air current passing through the lower end of the screen 2 and through the chute 8 and the upwardly directed air current passing through the lower discharge end of the chute 1O converge and act to carry the chat? and impurities over the said humped lower wall of the air duct extension to the fan casing, wherein is located a tan hereinafter mentioned and causing said air The walls 4: and 5 of the upper chute 8 terminate at their upper ends closely adjacent the lower ends of the screen 2 and screenQ respectively. The lower wall 9 of the other flaring end portion of the air. duct 7 slopes downwardly,and has an uninterrupted junction with the casing 11 of a suction fan 12, said casing being provided with a spout ertension13 and a valveboard 14. The air duct has unobstructed communication with the lower end of the chute 3 and with the upper end of the chute l0.
Suction being established in the duct 7 by means of fan 12, converging currents of air will be created, downwardly through chute 3, under wall 4, and upwardly through discharge chute 10, under wall 5, to said duct. A certain portion of the light matter to be eliminated will be separated from the grain as the latter falls upon deflector wall 5 and will be carried with the first stated air current into the duct 7.
As the grain leaves the longer wall 5 01": the chute 3- it will. be directed largely against the inner wall of the lower chute 10, and the air current passing across the lower end of the wall 5? and upwardly through chute 10 will tend additionally to direct said discharging material against said inner wall of the lower chute, whence the heavier grain will roll down through chute 10 and the lighter matter will be sucked upwardly along duct 7. The light matter separated from the grain by the converging air currents is now conducted to the tan casing 11 and blown out through spout 13. The volume of air is regulated by means of the valve board 14.
An inclined vibratory screen shoe 15 underlies at its upper end the discharge chute 10, and is adapted to carry a plurality of superposed screens 16. In order to enable a variety of seed and grain to be handled without changing screens, the shoe 15 is c0nstructed to accommodate two double screens and a single screen, the discharge from the upper screen being from the end of the shoe, in the? usual manner, and from the lower screens through four spouts 17, formed in the lower wall of the shoe.
A semi-inclosed base 18 forms a receptacle for the storage of screens, hopper, etc., for
shipment.
The partsmay be driven in any approved manner, preferably by a drive sprocket 19 having chain and sprocket connection 20 with a transverse shaft 21, connected with the fan shaft 22 by belt 23. Shaft 21 has also pitmen and lever connection 24 with shoe- 15 and with shoe 25 of the chaff screen 2, whereby both shoes will be vibrated, a rocking movement being imparted by means of pivot connection 26, in the Well-known manner.
I claim:
In a grain and seed cleaner, a vibratory screen, a screen board thereunder, a discharge chute at the lower end of said screen and screen board and having oppositely inclined imperforate walls, the outer of which is the longer and both of which terminate at their upper ends closely adjacent said scren and screen board, a fan, and a fan casing having an air duct extension having a single arched humped lower wall providing a contracted middle portion and flaring end portions, the lower wall of one of said flaring 20 end portions being inclined oppositely to and receiving material discharged from said longer wall of said chute and "forming therewith a second and lower chute and the lower wall of the other flaring end portion being downwardly inclined and having at its lower end an uninterrupted junction with the fan casing, said air duct having free and unobstructed connnunication with the lower end of the upper chute and with the upper end of the lower chute.
In testimony whereof I aifix my signature CHARLES N. HATFIELD.
