Description

one

The invention relates to agriculture and can be used in machines for harvesting raw cotton.

A cotton picker is known, which includes working bodies located on both sides of the cotton, in the form of transporters, which collect cotton when the latter is exposed to an electric field created by corona electrodes, some of which are intended for preliminary charging and cotton, and others for its collection and installed inside the conveyors, and located in front of the last loosening finger drums.

In the prior art apparatus, the belt conveyors are arranged in a horizontal plane and, when moving along rows of cotton, the bushes are very depressing, as a result of which the connection between the cotton slices and the bolls is broken. In addition, electrodes attracting cotton are fixed and therefore they do not participate in transporting cotton collected from bushes to the receiving device.

The goal of the inobregels is the smaller losses of the cotton being harvested.

This is achieved by the fact that, in P1), a device is placed, the cotton-preloading coronary skinny electrodes are located inside the loose finger-type drums, and the drums of trawlspliers are arranged in a horizontal plane, with the reference nx lolts moving from the bottom ver.x.

In addition, to ensure more on, -, reliable retention of cotton on T.iaucporter ribbons, the latter are made of a dielectric material with a twist of high volumetric and surface resistance and high dielectric constant and are filled with fingers of an elastic dielectric material.

FIG. 1 shows a cotton harvester, plan view; in fig. 2 shows section A-A in FIG. one; Fig 3 is a section BB in FIG. one.

Claims (2)

The apparatus contains on both sides a row of cotton working bodies in the form of thrashpatchers 1 s, a.P1 2, collecting cotton gfi on the latter by the electric field created by the corona electrodes 3 and 4, the first of which are intended for pre; (credentials, cotton and installed inside the loose drum 5 with fingers 6, and the second - to collect it, and installed-1 inside the conveyors 1, carrying drums 7 of which are located in a horizontal plane, and their tapes 8 moving upwards. A cotton picker hinged on a cotton picker works as follows: When a cotton picker moves, cotton bushes directed by bushes 9 pass between rotating and loose drums, which with their fingers break loose boxes, breaking into the cotton slices with them, and charge the latter with a positive electric charge. Then the fingers of the belt conveyors comb the bush from the bottom up, completing the disruption of the cotton slices with the bolls, and partially remove it from the latter. By the negatively charged conveyor belts, the cotton is oriented, attracted to the belt and carried out last from the zone to the receiving device. A high-voltage supply to the corona electrodes of the rippers and trans 5 5 Porters is carried out without contact from the direct current power supply point. Claim 1. A cotton harvester, comprising on both sides of a row of rhinestone working bodies in the form of conveyors, picking cotton when the latter is exposed to an electric field created by the corona electrodes, some of which are intended for pre-charging cotton, and others for its collection and installed inside conveyors, and loosening finger drums located in front of the latter, characterized in that, in order to reduce the losses of the collected cotton, previously zhayuschie cotton, discharge electrodes installed vnut ri friable otsih palmate drums and .barabany trasporterov arranged in a horizontal plane with their belts are moved upwards. 2. A cotton harvester according to claim 1, characterized in that, in order to more reliably hold the cotton on the conveyor belts, they are made of a dielectric material with high bulk and surface resistances and a high dielectric constant and are provided with fingers of an elastic dielectric material.  /; A A V Fig 2 B - B Fyg.Z:
