"SEED COTTON DISPENSING SYSTEM"
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION
The present invention generally relates to Seed Cotton Processing system, more particularly to seed cotton ginning and processing and even more particularly to an improved method and apparatus for dispensing and uniformly feeding the seed cotton for further processing.
BACKGROUND OF THE INVENTION
For every bale of cotton ginned approximately 800 pounds of seed must be handled from beneath the gin stands and placed either in a temporary or long-term storage facility. The bulk density of gin-run cottonseed averages about 25 lb/ft3 and requires about 80 ft3 of storage space per ton. Cottonseed is hygroscopic and therefore absorbs moisture from or gives up moisture to the surrounding air. Storage temperatures below 60°F and 10% moisture content wet basis (mc w.b.) provide best storage conditions.
The lobed blower normally used to handle cottonseed from the seed auger from inside the gin to the temporary houss can usually be used to transport seed to a storage building. These high pressures, low volume blowers can move cottonseed for long distances if they are properly sized. Valves located inside the seed house and movable pipe and seed deflectors can direct seed to the desired locations and effectively fill storage facilities with minimum management and cost. Removing the

cotton from the storage facility can be accomplished in several ways. A bucket loader dumping directly into a truck is the most common method at gins. Other use a lobed biower system to load cotton seed into rail cars, trailers or the temporary overhead house for staging shipments in open top trailers. Another effective method of elevating cottonseed is an old fashioned drag-chain conveyor or belt conveyor.
There are variations observed geographically in handling, conveying and storage of the seed cotton. Such that it is stored in bulk quantity as far Indian practice is concerned, in Africa it is stored in bags and in U.S.A. it is stored in modufe form. Hence the conveying system to convey seed cotton from storage places to individual ginning plants differs from place to place and country to country depending on ease of operation and quality storage.
A mobile spreader is disclosed in U.S. Pat. No. 4,449,648. This device comprises a tractor and a detachable hopper. The latter is defined by tapering front and rear walls and has a breadth permitting it to fit in between the rear wheels of the tractor. There is an elongate spreader opening in the bottom of the hopper, and an agitator adjacent to the mechanism driven by a roller to be brought into contact with one of the rear wheels of the tractor.
Another type of mobile spreader is disclosed in U.S. Pat. No. 4,155,315. This type is drawn by a tractor and includes a hopper mounted on a roller. The roller is provided with a jarring strip which imparts a jolt to the hopper on each revolution of the roller. This jolting action prevents bridging of the

material in the hopper, knocking the hung-up material down into the tower portion of the hopper where an agitator and an impellor further stir up the material.
Material handling in a ginning plant includes a number of units in operations that can be executed by mechanical or pneumatic means to convey the seed cotton. Raw material on which the processing has to take place in the ginnery is called 'Seed Cotton'. Seed cotton is moved from cotton heaps to Cotton Gins through pre-cleaners and distribution system.
Seed cotton conveying systems is in general classified into systems such as manual by directly feeding seed cotton into the system, mechanical conveying system like belt conveyors, screw conveyors and pneumatic conveying system using suction fans and ducting for material delivery to the required point.
However, in view of all the known methods and teaching of prior art there are drawbacks observed, such as, over and under feed of seed cotton to ginning plants, improper supply of seed cotton to each ginning machine, air separator jamming, more number of man power required to handle the operations, seed cotton fed onto the ginning plants may form into lumps due to uneven feeding that leads to reduction of the productivity of ginning machine, due to improper supply ginning machine gets more vibrations and jerks, the effect of vibrations leads to more wear and tear in ginning

machine and last but not the least the power consumption is very high in pneumatic conveying system.
OBJECT OF THE INVENTION
It is therefore a principal object of the present invention to provide a new and improved method and apparatus for seed cotton dispensing.
It is a further object of the present invention is to overcome the drawbacks associated with the existing conventional systems.
It is a still further object of the present invention to provide a consistent and uniform feeding of seed cotton hence resulting in higher productivity.
Yet another object of the present invention is to provide a sturdy, durable, simple, safe, efficient, energy conserving, reliable, easy to install, operate and maintenance.
An additional object of the present invention is to provide the aforementioned objectives with a minimum of labor and capital cost and power consumption.

Aspects of the present invention will now be described with reference to the accompanying drawings in which;

Figure 1 is schematic view of seed cotton dispensing system.
Figure 1 is a schematic view of arrangements of inclined spike rollers.
DETAILED DESCRIPTION OF THE INVENTION
The present invention generally relates to seed processing system, more particularly to seed cotton ginning and processing and even more particularly to an improved method and apparatus for dispensing and uniformly feeding the seed cotton for further processing.
Specific and additional features of the invention, as well as additional objects and advantages thereof, will become more readily understood and appreciated from the following detailed description of a preferred embodiment of the invention, taken in conjunction with the accompanying drawings, wherein referring now to figure 1- a Seed Cotton dispensing system (10) is provided wherein seed cotton (12) is fed from the top into the material stacking trench (14) wherein the conveying belt (16) moving in the trench with hopper (18) on which seed cotton is fed by tractor (20) by means of mechanical attachments resulting the movement of seed cotton. The conveying belt passes the seed cotton towards the plurality of rotating spike rollers (22) mounted in an inclined position onto which the seed cotton is fed by the conveying belt. The conveying belt is driven by an electric motor with (24) variable drive to control the feed to the spike rollers. Seed cotton passed through these rotating inclined spike rollers which results in uniform opening of the seed cotton and further discharging it through an

outlet for expelling and collecting it for storage and or further processing. As a consequence of this arrangement, seed cotton fed consistently and uniformly into the other processing systems (26) for further processing. The belt moves on it also acts as reservoir to store sufficient seed cotton for a continuous feeding for further processing as it synchronizes and gives sufficient time for reloading of seed cotton by means of tractor or any other suitable means.
Referring now to figure 2 wherein seed cotton passing through plurality of inclined spike rollers (22) which enables seed cotton open uniformly and fater is fed into the seed cotton stone removfng system (28) or any other relevant feeding system. The seed cotton from the conveyer belt goes into series of spike rollers mounted at an inclination. Said spike rollers are driven at fixed revolution per minutes (RPM). The spike rollers open the seed cotton which is then pushed out to the discharge followed by storage and or subsequent processing. There are plurality of belts and pulleys for motion transmission to other spike rollers in order to move them at constant speed. Spike rollers are mounted on formed angels of about 75x50x8 mm to about 75x50x10 mm which enables effective taking out of seed cotton without jamming or damage to the fibers.
spike roller are mounted on 16 mm or about thick plate in a unique staggering manner on roller such that the first column of spike roller angles on the cylinder have centers similar to the third column of spike roller angles whereas the centers of the second column of spike roller angles are offset with respect to first and third to give standardized and homogeneous output

of seed cotton on a continuous basis without any interruption resulting in facilitation of the opening and uniform feeding of seed cotton.
The roller angles of spike rollers ensures uniform supply of seed cotton without damaging the fiber properties due to rotating of the rollers with the surface speed of about 350 mtrs./ minute to about 390 mtrs / minute which is required for even opening of seed cotton to be processed
Accordingly the present Invention depicts the seed cotton dispensing system wherein the principle function of said dispensing system is to open up the seed cotton gently and uniformly feed the seed cotton for subsequent processing. Said dispensing system comprising, a belt conveyor with wavy top belt which is driven by electric motor with variable drive which consequently controls and monitors the feeding rate of said seed cotton as per specific desired requirement. Said belt conveyor carrying the material to series of rotting spike rollers mounted at an inclination at front of seed cotton dispensing system. Said seed cotton is passing through these inclined spike rollers which enables the opening up of the seed cotton without damaging the fibers and pushes it onto other processing systems. Said inclined spike rollers are driven at a constant; speed (fixed RPM) by a separate electric motor. The belt moves on it also acts as reservoir to store sufficient seed cotton for a continuous feeding for further processing as it synchronizes and gives sufficient time for reloading of seed cotton by means of tractor or any other suitable means.

The seed cotton dispensing system of the present invention has advantages in reducing the manpower cost, it avoids the damage in ginning machine while ginning, it also avoids the choking in pipe line of the pneumatic conveying system, it enables even supply of the seed cotton to the system, it controls the seed cotton supply by variable feed drive, it improves the productivity of ginning machine, it reduces the consumption of power and subsequent cost of power, it improves quality of lint, it minimizes the wear and tear in ginning machine and it has lesser contamination to seed cotton due to lesser manual handling of human invention.
