Abstract

Usage: in pneumatic apparatus of cotton-picking machines, Summary of the invention: the apparatus comprises an intake pipe and air-injection nozzles bent towards each other. When the movable cylinder rotates, its window alternately communicates with the windows of the stationary cylinder, while the flows of compressed air through the nozzles alternately act on the cotton bush. 2 ill.

Description

The invention relates to agricultural machinery, more specifically to cotton machines.

Cotton harvesting apparatuses are known comprising spindle drums, brush pullers, a lifting chamber and a drive mechanism. The spindle drum comprises upper and lower disks fixed to the shaft, between which there are twelve spindles, each of which is a pipe, on the surface of which four rows of teeth are cut. Spindles grab cloves of cotton, remove them from the opened boxes and wind them onto themselves. Brush pullers remove cotton from spindles.

Such devices are complex, expensive and not reliable enough. Every year, 100% of the harvesters have to be restored.

Also known are pneumatic clap- and cow-harvesting devices containing suction nozzles and vertical slotted nozzles with a breaker in the form of a cylindrical nozzle with

a longitudinal window installed with a cart; the possibility of rotation in a hollow stationary cylinder with windows adjacent to the nozzles.

The disadvantages of such devices are that the pressure of the air flows varies only in magnitude, which ensures high cotton pick-up efficiency. In addition, the design of the apparatus is not simple enough. .

An object of the invention is to increase cotton picking efficiency.

This goal is achieved by the fact that the windows in the fixed cylinder are located diametrically opposite along the working slit, and. slotted air nozzles are bent towards each other.

In FIG. 1 shows a cotton picker, side view, in FIG. 2 is a section AA in FIG. 1.

The discharge chamber of the cotton-harvesting apparatus comprises a hollow cylinder 1 with a bottom 2 and windows 3 and 4, to which nozzles 5 and 6 adjoin, bent towards each other. Inside the hollow cylinder 1 (or pipe 1) is mounted with the possibility of rotation

a cylindrical pipe 7 with a longitudinal window 8. Windows 3 and 4 are diametrically opposed along the working slit. The suction chamber 9 is located behind the longitudinal slit 10. When the cotton picker is operating, the longitudinal window 8 of the nozzle 7 is alternately combined with either window 3 or window 4. of the hollow cylinder 1., as a result of which (air flows alternately exert pressure on the cotton bush either left or right, whereby the cotton slices are torn off from the leaves of the box, after which they are sucked into the suction chamber 9 and enter the hopper of the machine.
