Abstract

The invention relates to an agricultural machinery industry, the purpose of which is to increase the efficiency of use of a cotton picker drum by knocking down fallen raw cotton from the ridge of the harvester and its mechanized selection. When the spike drum rotates along arrow A, elastic pegs 2 enter the zone between cotton bushes 9, and cotton slices 10 are pushed off from the ridge of the air, which moves along arrow C as it enters through channel 5 of the cavern 2 from channel 6 of the hollow shaft 1 Through openings 4 of elastic shells 3 under the action of outflow of air from channel 5, atmospheric air leaks along arrow D, which leads to the seizure of cotton slices 10 and its movement with spikes into the zone of action of the guide 7, which bends the elastic shells 3, which leads to overlap of expiration of air from the duct 5 and the removal from cotton elastic shells 3. Cotton sucked into the pneumatic tube system 11 machine. 1 il.

The invention relates to the field of agricultural machines, can be used in the design of cotton harvesting machines and is an improvement of the invention according to the author. St. No. 1376973.

The aim of the invention is to increase the efficiency of using the cotton drum picker by eliminating the loss of cotton on the ground and increasing the completeness of the collection of cotton pickers.

The drawing shows a General view of the Kolkova drum with a cut in the longitudinal plane of its shaft and one of the elastic pegs.

The pick drum of a cotton picker consists of a shaft 1 on which elastic pegs 2 are rigidly fixed. The bottom row of elastic pegs 2 carries additional elastic perforated shells 3 with through holes 4. The pegs 2 of the bottom row of the peg drum have channels 5 connected to channel 6 of shaft 1 of the drum. The elastic splittings 2 of the lower row are in contact with the guide 7 rigidly mounted on the frame of the apparatus 8. The elastic splittings 2 interact with the bushes 9 of cotton 10. From the direction of the guide 7 above the elastic splits 2 of the lower row, the suction nozzle 11 is placed placed in bearings 12 mounted on the frame of the apparatus 8. The channel 6 of the shaft 1 is connected through a nozzle 13 to a compressed air source of the cotton-picker (not shown).

Reel drum works as follows.

When rotating the drum drum, for example, in arrow A, the latter is

elastic spikes 2 interacts with cotton bushes, while part of cotton slices 10 falls downwards along arrow B. When they fall, the latter fall on the lower row of elastic spikes 2, "stick to them due to the fact that the air flowing out of arrow C from channels 5 creating a vacuum in the space between the elastic tip 2 and the perforated shell 3, draws air through the holes 4 along arrows D. To these same holes, but in the lower part of the shells 3, cotton sticking on the ground also sticks. Since the spike drum rotates along arrow A, the spikes 2 with cotton 10, moving to the right side, contact the guide 7 and elastically deform in their longitudinal plane. Such deformation prevents air from exiting along channel C from channel 5.

Since the pipe 13 is located above this peg 2 in this zone, the air moving in it along the arrow E pulls the cotton lobules 10 into the latter and transports it to the storage tank. After the elastic pegs 2 have left the sender 7, they are distributed, which again creates conditions for the unimpeded passage of air through the channel 5 and, consequently, the pickup and selection of the fallen cotton. The process is then repeated in the cycles described.
