The invention relates to agricultural machinery and may find application in cotton machines.

The aim of the invention is to improve the quality of the harvested cotton by reducing its injury.

In FIG. 1 shows a general view of a drum of a cotton picker; in FIG. 2 - a fragment of a drum with cotton elements; in FIG. 3 - chlokozahvatnye elements; in FIG. 4 - placing drums on a cotton picker.

The drum of the cotton-picking apparatus includes a vertical shaft 1, on which a cylindrical shell 2 is mounted, brushes 3 are located over the entire surface of which the ends of the radially spaced needles 4 of which are bent at an angle of 84-86 ° in the direction of rotation of the drum 2, which ensures a smooth brush surface. 3. To protect the plant from cuts, the cylindrical shell 2 is framed by a roller to the height of the brushes 3. To remove the fibers from the Brushes 3, elastic pullers are installed parallel to the shaft 1 (not shown).

The drum of the cotton picker works as follows.

3, the ends of the radially spaced needles 4 of which are bent in the direction of rotation of the cylindrical shell 2 at an angle of 84-86 °. Then the assembled working bodies are installed in pairs on a cotton picker (see Fig. 4). During the rotation of the drums and the movement of the cotton picker, the stalks of cotton with cotton bolls fall between the cylindrical shells 2, the fibers are captured by brushes 3 with the bent ends of the needles 4, and the leaves and stalks of cotton slide on a smooth surface formed by the bent ends of the needles 4 of the brushes 3, not I am injured. Rotating ahead of time, the elastic pullers remove the fiber from the brushes 3 and feed them into the hopper by pneumatic conveying, and the cycle repeats. ..
