Description

one

The invention relates to agricultural machinery and is intended for use in cotton harvesting machines.

A apparatus for harvesting cotton from opened boxes and a curaca is known, containing two pairs of spindle drums with pullers, receiving chambers and a pair of vertically mounted rollers with smooth blades rotating at different speeds and pitched guides 1 which are counter-rotating at different speeds.

However, the known apparatus has a number of drawbacks in that, when cotton bushes meet in a narrow working slot with a blade roller, which has a high speed, a dynamic impact occurs due to which a separate box, slice or bat beat off, not falling into the working area, fall to the ground. However, the main part of curative cotton, falling into the working slot, is caught by the blades of the rollers and, due to their different rotational speed, is subjected to crushing, peeling, stretching of the cotton slices and a single, temporary deposit of them on the working surface of the spindle of the second pair of drums. With

This crushed raw cotton mass is thrown onto the drum, which is behind the high speed roller, and the opposite drum remains unloaded. This leads to the fact that the loaded drum is not J in the state of seizing all the raw cotton and, as a result, the individual lobules and tetons fall to the ground.

The purpose of the invention is to increase the completeness of the cotton harvest.

This is achieved by the fact that the apparatus is equipped with a guide plate mounted in the inter-drum space in front of the high-speed roller, and the low-speed roller is installed with a relatively high-speed offset in the direction of movement of the device.

FIG. 1 shows a diagram of the proposed apparatus, top view; in fig. 2 - rollers installed in the inter-drum space.

The device consists of two pairs of successively located spindle drums 1, 2 with pullers 3 and receiving chambers 4. Before the second pair of drums 2, low-speed 5 and high-speed 6 blade rollers with pitched guides 7 and guide plate 8 are installed with some displacement.

The device works as follows.

As the maschine moves along the rows, the cotton bushes are compressed by counter-rotating drums 1 and 2, the spindles of which draw cotton fibers from the opening boxes. Closed (curated) and half-opened cotton bolls, exit from the working gap of the first pair of drums 1, first enter the slot formed by the guide plate 8 and the low-speed roller 5, where the cotton bushes are gradually compressed, compressed and smoothly directed into the working slot formed by the blade. rollers rotating at different speeds. In the working gap of the blade roller 6, which has a high speed (high-speed), it performs crushing and peeling of the bolls, stretching the cotton slices from the bolls, as well as a uniform sling of the crushed cotton mass in the form of a pile on the working surface of the second pair of drums 2.

The uniformity of the heap is achieved by displacing the low-speed blade roller 5 forward with respect to the high-speed 6 and thereby displacing the pile of angle of the pile of blades of the high-speed roller 6 towards the unloaded spindle drum.
