Description

Machines are known for harvesting cotton during the opening of cotton bolls, equipped with a pneumatic operating apparatus made in the form of suction nozzles that interact directly with the cotton.

Also known are devices for harvesting unguided cotton bolls made in the form of metal combs separating the unopened bolls from the cotton bush.

The disadvantages of such devices are the insufficiently effective processing of cotton bushes, caused by unequal loading of nozzles along the height of the bush, as well as the need for separate harvesting of raw cotton and kurak.

In the described device, these disadvantages are eliminated by the fact that for a more efficient processing of a cotton bush with a more uniform loading of nozzles, the working chamber is made cone-shaped with inclined nozzles carrying inside the comb. To carry out the simultaneous separate harvesting of raw cotton and coconut or only coconut, the working chamber has a bottom nozzle with a trough-shaped edge, the smooth edge of which acts on the box together with the turning bottom edge of the upper nozzle.

The drawing schematically shows a side view of a pneumatic working apparatus and a cross section along AA.

The working device consists of two cone-shaped chambers 1 and 2, visited by a tractor or a self-propelled carriage and its own outlet pipes connected to the suction fans. The camera / is moved forward relative to camera 2, and the bottom edges of both cameras are inclined to the horizon with a code angle of 25-35. Between the chambers, a working cavity 3 is formed, facing into the working gap. Along the working edge of the front chamber / passes the nozzle 5, V of which on the outer wall 6 is installed along the entire length of the comb 7. 7. The nozzle S located below the nozzle 5 passes along the working edge of the rear chamber 2. The outer wall of the nozzle 8 below has a trough-shaped bend 9 with a smooth with the edge forming a working slot 4 with the wall 6 of the nozzle 5. To change the width of the latter, the lower part of the wall 6 is made rotatable (not shown).

When harvesting raw cotton and kurak, the apparatus operates as follows.

The cotton bush, hitting the slot 4 and the working space 3, is exposed primarily to the front nozzle 5. The vacuum created by the fan in the chamber 1 extracts the fiber from the fully opened bolls. From the half-open boxes, the fiber by the vacuum nozzle 5 is not fully drawn; it stretches partially over the length of the cotton slices; the latter are hooked onto the comb 7 and, thanks to the forward movement of the apparatus, are pulled forward out of the box. From the comb, the cotton is removed gradually. All cotton from chamber J is transported by fan to a hopper. Due to the inclined position of the nozzle 5, the bush is processed along the entire height of the open and semi-open bolls.

The nozzle 8, which goes somewhat lower and behind the nozzle 5, breaks off the kurak: the kurak, created by vacuum in chamber 2, bends down to the left through edge 9 and, held to the right by wall 6, breaks off and is transported from chamber 2 to a separate bunker. At the same time, the raw cotton passed by the nozzle about and left in the boxes was taken by the nozzle 6 and sent to the same bunker as the kurak.

When only cotton is harvested, the slit 4 is increased by turning the wall 6 to the right to a size that ensures free passage of the bush with chickens and sashes; Both nozzles 5 VI 8 work on the extraction of raw cotton.

When the cleaning machine is operated, only the crack 4 is narrowed to the limit; only

the nozzle 8, by removing the kurak with the edge 9 and glass 6, and the nozzle 5 is inactive and can be turned off.

Subject invention

Claims (5)

1. A working machine for a cotton picker of pneumatic operation with the use of crimping from the lateral sides a cotton bush of a chamber with a slit R of its bottom for the passage of the bush and with suction nozzles connected to it acting in direct contact with the chamomile, which has by the fact that, for the purpose of consistent processing of the bush along its height from the bottom upwards and the implementation of a more uniform loading of nozzles, the chamber of the apparatus is made cone-shaped with inclined nozzles brought to it, spaced one above the other and are parallel slots for the passage of the bush. 2. The form of execution of the working apparatus for and. 1, characterized in that, in order to facilitate the removal of raw cotton from the opened and semi-opened bolls, the nozzles are provided with their combs located inside, which act on the segments of the cottonsex drawn into the nozzles. 3. Variations in the working apparatus according to claim 1, characterized in that, in order to carry out simultaneous harvesting of raw cotton and unripe boxed cotton-kurak from the bush, only the lower nozzle of the apparatus is limited from below by a trough-shaped rib with a smooth edge. 4. The form of execution of the working apparatus according to claim 3, characterized in that, in order to better press the cotton bush to the lower nozzle, the lower edge of the upper nozzle is made rotatable. 5. The form of execution of the working apparatus according to paragraphs. 3-4, characterized in that, in order to carry out separate removal from the cotton bush and hen, the apparatus nozzles are attached to separate fans and bins.
