Description

The proposed machine is intended to separate cotton fiber from the seeds to which the fibers are attached while growing.

Existing gins are usually supplied with fixed grates, on which a raw roller is formed; therefore, the work is carried out with a large difference in the speeds of the saws and the raw roller, which is a major obstacle to the proper operation of the gin, both in quantitative and qualitative relations, since mechanical damage to the fiber covers, ruptures of long, etc. are obtained. eliminating these shortcomings in the proposed genie, the fixed grates are replaced by rotating noltsevny grates, which surround the raw roller, and which, due to the minimal friction between them and their supporting surfaces (friction quality) neither) have almost the same circumferential speed with saw blades, which achieves a soft, shock-free penetration of the saw teeth into the mass of the raw roller and due to this is the impossibility of mechanical damage to the fibers and their

rupture. The proposed gin is intended to apply it to existing machines, therefore both the body itself and most of the machine parts are left unchanged; only the grate bars, whose design in the proposed genie is intended to rationalize the process of jinn, have changed.

In FIG. 1 shows a longitudinal vertical section of a gin; FIG. 2 is a front view of the machine with partial cuts; and FIG. 3-t is the same, top view with partial cuts.

The working process in the machine is as follows: raw from a feeder of any type enters the shell) stitching chamber 1 (Fig. 1), is picked up by a rotating roller 2 with studs inserted into it, loosened by them, cleared of possible impurities and thrown onto rotating saw disks 3. The raw material picked up by the wire and hooked by the saw teeth, is pulled through the cuts of the iron shield 4, and through the gaps between the rings 5, which are sufficient for the passage of fiber pubescent shells, enters into the internal cavity of the cylinder, zable 5 rings.

Rings 5 are supported on rollers b, 7 and 8 (Figs. 1 and 2), provided with grooves to maintain the constant position of the relative position of the rings and resting their axes on the bearings 9. The teeth of the disks 3, pulling raw lumps inside the rings, are small fill the entire internal cavity and form a raw roller 10 enclosed in these rings, and since the rings 5 have resistance to their rotation only rolling friction on the rollers 6, 7 and 8, a significantly smaller friction on a stationary surface, the speed difference between the saw and the raw roller can not be significant oh and purification process occurs at almost equal speeds. The fiber captured at the first moment of contact of the saw tooth with raw lumps cannot slip out of the tooth cavity, and this cavity, while further advancing in the mass of the raw roller, should be further filled with fiber to advance it to point 11, where the tooth fits tangentially to the inside forming a ring 5. At this point, in the gaps between the rings 5, steel plates 12 are inserted, reducing the width of the gaps between the rings, so that during the passage of the saws it is difficult to pass the seeds through the cuts. These plates are screwed to the cast-iron bracket 13, a set of them, according to the number of inter-gap gaps, are screwed to the cast-iron bar 14, fortified movably between the frames of the machine. This mobility is necessary for mounting the steel plate 12 exactly tangential to the inner circumference of the rings 5, which is achieved by placing the side slit of the beam 14 on the rod, poured into the brackets 15. The latter are firmly screwed to the side frames of the gin; The adjustment of the position of the plate 12 is made by stop screws raising or lowering the bar 14. Approach to point 11 saw teeth with hollows filled with fiber not yet separated from the seeds pass through the gaps between the rings and the plates through which the seeds cannot pass. Therefore, the fibers trapped in the hollow, under the pressure of the saw tooth, are detached from their seed and dragged into this slot beyond the outer surface of the rings. Here, the saw teeth with fiber entrained by them fall under the action of the air flow developed by the rotating brush drum 16 and the action of this air stream (and partly possibly by the mechanical action of the bristles) of the fiber is cleared from the saw and directed along an inclined board 17 to the condenser .

Remained in the mass of the raw roller, deprived of fiber, the seeds, as a result of adhesion, participate in all movements of the particles of the mass of the raw roller under the action of the saw teeth. As they are cleared of fiber, the seeds fall out of the mass along the iron flap 19 over the spaces between the disks 3 and pour out of the car along the tray 20.

The subject of the patent.

A gin, based on the principle of operation at almost equal speeds of saw blades and a raw roller, characterized by the use of a grate drum composed of rotating bolt 5, supported on rollers b, 7 and 8, and receiving into the internal cavity through the intervals between the rings the cotton from the saw The discs 3, which are cotton using plates 12, filling the gaps between the rings 5 and the discs 3, are divided into fibers removed by a brush drum 16 or a stream of air, and on seeds falling along the plates C 19 downwards.
