4= Claims; 1
This invention concerns cleaners for mechanical cotton pickers. I I I It is well known that many mechanical cotton pickers gather, along with the cotton, an excessive amount of dirt, leaves, dried fragments of bells, and stems. This lowers the grade of the cotton and makes it necessary for the gin to put the cotton through an extra cleaning process, the cost of which is deducted from the price of the cotton delivered at the gin.
While cotton may be cleaned after it has been transported to the gin it is harder to clean at this time because the dirt has been worked into it during handling and transportation and hasbecome broken into small pieces and enmeshed throughout the cotton fibers. It is much more desirable to remove the dirt immediately after picking and before the cotton enters the receiving cage of the picker.
In view of the foregoing, one of the objects of my invention is to provide a cleaner which may be installed in the delivery duct of a mechanical cotton picker wherein the cotton is conveyed from the picker spindles to the cage by a current of air;
A second object is to provide a cleaner for a picker of the type described wherein the dirt and trash is separated from the cotton before the cotton enters the receiving cage; I
I A third object is to provide a cleaner of the type above mentioned which will separate dirt and trash from cotton blown through a duct to the receiving cage, by use of the air currents flowing through the duct and without the use of mechanism driven separately from the blower of the picker. I
Other objects will appear hereinafter.
I attain the foregoing objects by means of the structure devices and combinations of parts shown in the accompanying drawings, in which Figure 1 is a perspective view of the cleaner as applied to the cotton delivery duct of a mechanical cotton picker; I I I I I Figure 2 is a sectional side elevation thereof;
Figure 3 is a front elevational view of the cleaner with parts of the outer covering broken away to show the interior; and I Figure 4 is a perspective view of the cleaning id.
Similar numerals refer to smiilar parts in the several views. I I I Air with cottontuft's entrained together with a certain amount "of trash, redrawn from the pieking mechanism "(not -'showh-) "by blower 2 and forced from blower putle't 3. The "cleaner body "6 2. extends from the upper end of outlet 3 to cotton receiving cage l, as shown in Figure l.
The cleaner 6 consists, in general, of a duct I0 having its lower end joined to blower outlet 3 and its upper discharge outlet joined to cage 4, a low pressure chamber 1 2, a deflecting and turbulating bafiie I 4, a vibratable grid f5, covering a trash escape opening, and a trash removal duct [6.
More particularly, the body 6 of which includes duct 10 extends upward from its lower end to a position in its'upper portion and then bends" at curve 1 to form a short horizontal upper portion which terminates at outlet 46 and opens into cage 4.
Just below the bend l a trash escape opening 23 is formed in the composite outer wall of duct l0. Below this opening the outer wall of the duct 19 is formed by plate H? which also acts as a separation plate between the lower portion of duct Ill and the trash removal duct 06. Above this opening the outer wall plate 3i of body 6 forms the outer wall of duct Ill.
The upper edge of trash escape opening 23 is formed by a sharp outward bend 29 in outer wall plate 3! of the body 5. The lower edge of this opening is formed by'the upper edge of plate I8. The back portion of duct I0 is enclosed by back wall plate 25 of body 6. The back and outer walls of cleaner body 6 are joined at their lateral edges by side wall plates 3! and 38. The entire duct has a substantially rectangular section. The vertically extending lower portion, however, is nearly square While the short'horizentally extending upper portion has a wide transversely extending rectangular section.
Opening 23 -'conn'ects-duct it to low pressure chamber l2 and is formed by an outwardly rounded hump 3D in the "outer wall 3| just beyon and below bend 29'. This wall portion ex- 3 tends downward from hump 30 somewhat parallel to the plane of plate I8, but at about the bottom of opening 23 it curves inward and outward again forming a Venturi throat 33. The trash outlet duct 16, formed between plates 3| and I8, then extends downward to trash vent 35 where it opens to the atmosphere.
A humped V-shaped bafile M is attached to back wall 25 ofduct l slightly above the central portion of opening 23-. Its purpose is to deflect air and entrained particles of trash 26 toward opening 23 and toward grid [5. The deflection of the air, as indicated by arrows 21a, causes a turbulence indicated by arrows 28 which breaks the velocity of the particles of trash 26, but does not greatly afiect the flow of lighter tufts of cotton 21.
In operation, the duct I0 is incorporated in the picking machine with the inlet 39 connected to the outlet 3 of the blower 2. Air, with entrained cotton and trash, is driven into duct 10 and the main body of the flow is forced through outlet 40 into the receiving cage 4. This outlet is restricted, however, so that an appreciable amount of air is forced through trash outlet Opening 23. Some of this air enters the low pressure .chamber I2 due to pressure differential, and some enters due to the inertia of flow caused by the turbulating baflle l4, and due to the fact that the opening is on the outside of the bend I of upper curved portion of the duct. As pressure from the air stream forces the air in the low pressure chamber l2 on out from the trash outlet duct 16 it passes through the Venturi throat 33 and increases in velocity. This is suihcient to quickly draw and induce any trash particles in the low pressure chamber into duct l6, and to force them from outlet 35.
The movement of air and trash particles from duct ID to low-pressure chamber I2 is irregular and while trash particles may be thrown against the grid by the velocity of their movement through duct ID, as they curve around bend I, their movement in low-pressure chamber is slow and they are inclined to eddy whirl about in the chamber. The increased velocity of the air in the Venturi throat 33 tends to quickly draw them out, however, so that they are forcefully expelled from outlet vent 35. If opening 23 were exposed directly to atmosphere the flow effective to eject trash would clog up the grid with cotton tufts. To be efiective there must be an eddying action of varying pressures acting through the grid from duct It! to chamber l2.
The spring rods of grid are spaced sufliciently close to retain all tufts of cotton 2'! within the duct H], but are a sufiicient distance apart to permit passage of trash particles 26, Since these particles are of irregular shapes, they are inclined, at times, to hang up on the grid wires. However, due to the vibration of the air from the blower and to the always present irregularities in air flow through the grid, these particles move from their place of lodgement and cause the rods of the grid to yield slightly and, thus permit them to pass into the low pressure chamber l2. During operation the rods of the grid vibrate, somewhat, at all times. They not only pick up vibration from the air stream, induced by the heating of the blower blades, but pick up vibration from the other parts of the picking machine. Since their upper ends are free no cotton is retamed on them. All tufts that may be temporarilycaught on the grid wires slide or roll oil 4 the ends of the wires, and again enter the air stream in the duct l0.
It is to be understood that the action of the turbulating baffle is important in that it causes an eddy or turbulence 28 in the air stream in the duct. This momentarily slows the velocity of tufts of cotton containing trash, tends to spin them and to dislodge the trash, and decidedly slows the denser and heavier trash particles. At the same time the eddy tends to deposit them, or direct them toward grid l5.
From the foregoing it will be understood that I have provided an easily made and efficiently operating trash removal device which cleans the cotton as it comes directly from mechanical picker and before it has had a chance to become imbedded in the cotton bolls. This device can be easily installed in the duct which ordinarily goes from the blower to the receiving cage of many types of mechanical pickers. In a sense, the body 6 of the cleaner, including particularly duct Ii], becomes a part of duct 3. It takes the place of the upper part of this duct and the upper part of duct i0 discharges thru outlet 40 directly into the cage 4.
After installation no further care is needed. The operation is automatic.
Whereas I have shown the preferred form of the device it is to be understood that I intend to claim the form herein illustrated and all mechanical substitutions of the several parts.
