Abstract

The invention relates to the textile industry and can be used in cotton plants for trapping undergrown seeds and volatile raw cotton. The aim of the invention is to simplify the design and improve the efficiency of seed sorting. This is achieved by the fact that the device for sorting cotton seeds contains a bunker feeder, a net seeding sorting drum with a window in its final section for outputting underdog seeds, and trays inclined under the drum with the possibility of oscillatory movement. the sifting surface for under-gened seeds, and the seed agitator, installed by means of radial arms along the axis of the drum with the possibility of interaction with its inner surface and vras, opposite to the drum direction. Moreover, the input section of the latter is made conical. 1 hp f-ly, 2 ill. S (l

The invention relates to the cotton industry and can be used in cotton plants for trapping underdog seeds and cotton bales.

The purpose of the invention is to simplify the design while improving the sorting efficiency.

FIG. 1 shows a device for sorting cotton seeds; in fig. 2, section A-A in FIG. one.

A device for sorting cotton seeds contains a hopper feeder with a drum feed drum 1 and a hinged flap 2 installed with the possibility of changing the distance to drum I to adjust the thickness of the seed flow, the inclined tray 3 for feeding seeds into the mesh seed sorting drum 4 with a cone-shaped entrance section 5 and a window 6 in its final section for outputting under-ginned seeds. Under the drum 4, the trays 8 and 9 are obliquely mounted with the possibility of oscillating motion from the vibrodrive 7, the upper of which is solid, and the lower one has a screening surface 10 for underdog seeds and is mounted on elastic plates 11. On the axis of the drum 4, the agitator is mounted on the axis of the drum 4 in the form of a screw blade 13, interacting with the inner surface of the drum. The blade 13 is rotatably mounted in a direction opposite to the drum. The propeller blade can be made elastic or have an elastic tip, and the agitator itself can be made multiple. The bass is collected in the flat, stationary drum 14 that encloses it. Tray 15 is used to collect the underdog seeds, and a slot 16 is provided at the bottom of the solid drum 14 for withdrawing seeds to the upper tray 18.

The device works as follows.

The seeds coming out of the gin come to the hopper feeder 1, which provides the even feeding of the whole seed on the inclined tray 3 into the mesh chamber of the sorting drum 4 through the cone-shaped entrance section 5. Inside the drum, the seeds are loosened with the help of the agitator, installed in the form of a helical blade 13, and move in the axial direction. As a result of the interaction of the blade 13 with the inner surface of the drum, the seeds with normal pubescence fall through the mesh opening and down the surface of the drum 14 go down to the tray 8 and through it

tied out. Together with the underexposed seeds, part of the normally processed seeds leaves through the discharge port 6. These seeds arrive on the surface of the inclined grid 10, which by means of the vibrating conductor 7 receives oscillatory movements. Seed-by-layer displacement of seeds is formed on the surface of the net during vibration. Underdeveloped seeds with fibers and cotton tufts of lesser density, having a lower density, form the upper layer. In the lower layer are normally treated seeds and they, moving over the mesh surface, fall through the mesh holes, separating from. the masses, and are transported through tray 9. Separated underdog seeds and cotton stains arrive at tray 15 and are transported via a re-jining pipeline.

When the mesh drum operates with a helical blade, seeds are loosened with simultaneous axial movement and sorting. To create normal axial movements of the seeds, without damaging them, elastic tips have been installed on the blades, which ensure the cleaning of the grid surface and the uniform exit of normally treated seeds through the discharge opening. The simultaneous rotation of the mesh drum and the helical blade in the opposite direction makes it possible to use the entire grid area.

Thus, while simplifying the design, complete recovery of the undegraded seeds and cotton bales of the raw cotton is carried out in a continuous technological process and the fiber yield from the raw cotton increases, and consequently, its losses are reduced.
