Abstract

The invention relates to the field of agricultural engineering, in particular to machines for the harvesting of raw cotton. The purpose of the invention is to improve the quality and completeness of the collection of raw cotton. This is achieved by using a pulsating air flow, a toothed drum 3 and a diametrical fan 6. When the machine moves along rows of cotton, a pulsating air jet supplied from the working nozzles 2 removes the raw cotton and presses it to the toothed drum 3, which seizes it raw cotton and presses to the toothed drum 3, which, capturing it, enters into the transport channel. Small crap from the working area is sucked through the passageways by the diametrical fan 6 and is thrown out through the outlets. Similarly, raw cotton is harvested from the second half of the cotton bush. 1 hp f-ly, 3 ill. ABOUT)

The invention relates to agricultural machinery, in particular to machines for collecting raw cotton,

The purpose of the invention is to improve the quality and completeness of the collection of raw cotton. FIG. 1 schematically shows the apparatus of a pneumatic mechanical cotton picker, plan view; in fig. 2 is a section A-A in FIG. 1; on fig.Z - node I in fig, 1,

The working apparatus of a pneumatic-mechanical cotton-picker consists of pressure nozzles 1, located on both sides of the row of cotton being processed, nozzles 2, arranged in a checkerboard pattern and directed to rotating gear drums 3, also arranged in a checkerboard pattern. The flow channels 4 are made on the rotating drum 3 which forms, and the casing 5 of the diametrical fan 6 is made with perforations, installed inside the rotating drum 3 and is pneumatically connected to the nozzle 7 connected to the transport channel of the pneumatic conveying system.

The working apparatus of a pneumomechanical cotton harvesting machine works as follows.

When air is fed into the pre-blowing nozzles 1, a row of cotton and nozzles 2 rotate the toothed drum 3 and diametral fan 6. When the machine is moving, dry leaves and dust are removed from the bushes with cotton pulsation and then bushes when the machine moves. the cotton is affected by the pulsating air jets injected from the nozzles 2. In this case, the extracted raw cotton is caught by the teeth of the rotating drum 3 and is supplied by the air flow created by the fan 6 to the nozzle 7. In addition, it is rotated The toothed drum 3 facilitates the entry of the cotton bush into the working area, with the teeth of the drum 3 turning at a certain angle around its own axis in connection with the rotation limiters installed on them and taking the direction necessary to pick up raw cotton from the working areas of the Through channels 4 and the teeth of the rotating drum 3 are formed; windows whose dimensions are smaller than the size of the hens
