FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular cotton harvesting machines for collecting cotton.

The cotton transport system, known as a non-conveying system, is well-known, and the receiving chambers, fans and pipelines equipped with a dividing partition, a separator with a cylindrical cellular surface.

1 Known cotton harvesting machine, the partitions of adjacent pipelines of the pneumotransport system of which are made of mesh, which allows equalizing the air flow of the pipelines 2.

In known machines, the pipelines are divided by partitions parallel to separating the surfaces to it, therefore, the pipes come one above the other to the bunker. Cotton enters the bunker from the upper rus by the bottom pipe, and from the lower rus by the upper pipe. This arrangement of the pipeline leads to the fact that when filling the hopper with cotton, the transporting air is not able to bleed through the mesh of the hopper and through the slit chamber to the bleeder. This violates the technological process of work of the cotton harvesting machine. Bleeding the air with known techniques in the pneumatic system of known devices cannot be done, since one pipe is located above the other, which can cause the cotton of the lower russ to mix with the cotton of the upper rus. This is undesirable when picking cotton. In addition, when two pipes are brought to the bunker one above the other with a partition that forms parallel to the separator forming part, it is almost impossible to separate the cotton litter coming into the bunker through the bottom pipe, and all the rubbish from the top of the rus falls on the cotton in the bunker collected with lower rusov, which increases the weediness of cotton, collected from the lower rusov.

The purpose of the invention is to increase the reliability of the process and improve the cleaning effect of the separator. In the proposed system, this is achieved by the fact that the dividing walls of the pipelines,

guides the cotton into the separator of the bunker, installed perpendicular to the generator of the working surface of the separator.

FIG. 1 shows a cotton picker pneumatic conveying system, side view;

in fig. 2 - the same system, front view.

The device comprises a fan 1, an air pipeline 2 and a receiving chamber 3, which has a vertical partition 4, dividing the chamber into two equal areas.

a compartment for receiving cotton from the bottom and upper Rus, and attached to the cotton picker b. Pipelines 6, in which partitions 7 are installed, are installed perpendicular to the generator of the working surface of the separator 8.

During the operation of the machine in the field, the cotton collected by the spindle drums is removed by pullers and transported to the receiving chamber 3, in which the partition of the cotton flow takes place by means of the partition 4 into the Rus. Air from fan 1 through line 2 enters the receiving chamber, where it picks up the cotton in it and transports it to the bunker 9 of the machine through pipelines 6. Before entering the bunker capacity, cotton enters the separator 8 and, as separating The partitions of the cotton pipelines, installed perpendicularly to the generator of the working surface of the separator, pass through its entire width, which allows for high-quality separation of small

cotton litter collected from the lower and upper Rus bushes cotton.
