FIELD OF THE INVENTION The invention relates to agricultural machinery of cotton, namely to cotton harvesting machines.

The purpose of the invention is to increase the efficiency of picking raw cotton by increasing the duration of exposure to the treated bush and simplifying the design.

FIG. 1 shows a cotton picker schematically, plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view of B in FIG. 2

Cotton harvester. Apparatus .. contains spindles 1 installed on. chain conveyor 2, tensioned on tseduschy 3 and driven 4 asterisks.

The conveyor 2 encloses the receiving chamber 5, which is open towards rows of cotton bushes (Fig. 2, line 00), for directing bushes 6 to the gap between the conveyors.

To bring the shaft 7 into a swinging movement around the vertical axis, the levers 8 and 9, mounted on the shaft 7 and interacting with the stops 10 and 11 during the movement of the conveyors 2, serve.

The spindle 1 comprises a shaft 7 placed with the possibility of swinging in the holes of the fixed angles 12 and 13 mounted on a bracket 14 attached to a link of the conveyor 2.

The gear washers 15 and 16 are located on the shaft 7, and the washers 16 are fixed relative to the bracket 14, and the washers 15 are mounted on the shaft 7 by means of a splined joint.

To prevent excessive displacement of the washers 15 and 16, spacer sleeves 17 are mounted between them on the shaft 7.

Cotton harvester works as follows.

When the machine moves along the row along line 00, cotton bushes enter the gap between the left and right conveyors 2 (Fig. 1) with bearing spindles 1 and levers 8 and 9. Since the stops 10 and 11 are fixed stationary relative to the machine, the levers 8 and 9 interact with the stops 10 and 11 and turn the shaft 7,. provide him with a swinging movement. Together with the shaft 7, toothed washers 15 swing.

An air jet sucked into the receiving chamber 5 through the gaps between the spindles 1, carries the fiber into these gaps and presses it to the gear shaft 15.

By the way, the washers 15 take the fibers of raw cotton with their teeth, push it into the gaps between the spindles, and tear it away from the bolls.

The reverse movement of the cotton fibers is prevented by the teeth of the fixed washers 16.

The areas of the washers 15 located on both sides of the gap between the spindles 1 move simultaneously in different directions, which prevents tightening of the n between the washers: 15 And ... solid Objects (KopOj neK, branches of cotton and so on. )one; ;

The fibers of the raw cotton entering the receiving chamber with an air stream of the pneumatic system are transported to a bunker, in the upper part of which a cotton cleaner can be installed to partially remove the litter sucked from the row. Placing the spindles on the elongated conveyors increases the time of the impact of the working bodies of the apparatus on the cotton bush and allows for a more complete removal of the ripened raw cotton.

The design of the proposed apparatus is less metal consuming and allows to reduce the energy consumption during the removal of raw cotton.
