The invention relates to agricultural machinery and is an improvement on the cotton harvesting apparatus described in ed. Ns 1665924.

The main invention describes a cotton-harvesting apparatus comprising a conveyor enveloping in a horizontal plane a receiving chamber with a pneumatic conveying system, spindles made in the form of a shaft with gear washers mounted on a conveyor with the possibility of swinging around a vertical axis and with gaps between the shafts. Toothed washers are mounted on the shaft with a shift of their center from the swing axis. Spindle shafts are oval in cross section. Air sucked into the receiving chamber through the gaps between the spindles from the working gap draws well-opened cotton to the toothed washers. Therefore, the working gap in the apparatus of the prototype can be made much wider, with all other known devices.

The disadvantage of the prototype apparatus is the impossibility of timely removal of cotton ripened in the lower rus without damaging the unripe cotton in the upper rus of the cotton bushes. Therefore, one has to wait for it to mature in the upper reaches, but at the same time the cotton of the lower Rus overrides and begins to fall to the ground, increasing the loss of the most valuable part of the crop.

It is an object of the invention to provide light cotton picking.

The goal is achieved by the fact that the apparatus for autosw. Ne 1665924 is equipped with removable shields mounted on the frame on both sides of the working slot to cover the upper part of the spindles.

The cotton picker made in this way can be used to harvest cotton from the lower bed before it ripens in the upper beds.

In FIG. 1 is a schematic illustration of a cotton picker, plan view; figure 2 is a section aa in figure 1.

The proposed apparatus contains left and right sections, placed on both sides of the working slit 0-0 (figure 2).

Each section contains a chain conveyor 1 mounted on drive 2 and tension 3 sprockets. To ensure synchronization of movement of the lower and upper chains of the conveyor, the lower and upper sprockets 2 are mounted on a common shaft, which

kinematically connected to a power take-off shaft of a cotton picker (not shown in Fig.).

On the plates 4 of the conveyor chains, spindles 6, oval in cross section, are mounted on the x axis 5. At the upper end of each spindle, levers 7 and 8 are strengthened, which have the ability to interact with the movement of the conveyor with stops 9 and

10, mounted on the frame 11, providing a swinging movement of the spindles 6. The toothed washers 12 are mounted on the spindle eccentrically.

Shields 13 covering each section

from all sides except the side facing the working gap 0-0, form a receiving chamber into which the pipe 15 of the pneumatic conveying system is inserted.

Removable shields 14 are hung in the area of the working gap to cover the upper part of the spindles.

Cotton-harvesting apparatus operates as follows.

When the machine moves along the row, the cotton bushes enter the working slot 0-0, the width of which is maximum at the first harvest (about 100 mm). To the frame 11 in the area of the working gap, removable shields 14 are hung, covering the upper part of the spindles 6.

Air is sucked into the receiving chamber through the gaps between the spindles and pulls the opened cotton to the toothed washers 12, which grab it and push it with a swinging motion

inside the receiving chamber. Through the pipe 15, the cotton removed from the lower bed of the bush is transported to the hopper of the machine.

Since the upper part of the spindles at

the first collection is covered with shields 14, the ripening cotton is removed only from the lower bed. Unripe cotton of the upper bed is protected from mechanical damage by shields 14 and continues

normal development.

In subsequent collections, the shields 14 are replaced with narrower ones or completely removed, and the width of the working gap is reduced.
