Abstract

The invention relates to agricultural machinery and can be used to harvest raw cotton from harvested cotton bushes. The purpose of the invention is to reduce the clogging of curative cotton. The device is equipped with a separator located between the shelling rollers 3 and the lower pair of 6 spindle drums and made in the form of a drum 4 with blades and a separating net 5 located to the side of it. The lower pair of 6 spindle drums is displaced in a horizontal plane relative to a pair of sheave rollers 3 in the direction from the separating net 5. A pair of 2 spindle drums removes cotton from the opened bolls, which enters chamber 9. Shelling rollers 3 are crushed into kurak, after which the blade drum 4 is pulled bushes for separating grid 5 is recovered from mass bush trash. Curative cotton is removed by the lower pair of 6 spindle drums and guided into chamber 10. The displacement of the lower pair of 6 spindle drums relative to the pair of shearing rollers 3 prevents the direct debris from entering the working gap of the lower pair. 1 or Ј

Description

The invention relates to agricultural machinery and can be used to collect raw cotton from harvested cotton bushes.

The purpose of the invention is the reduction of weed cotton clogging.

The drawing shows a diagram of a device for collecting raw cotton from cut bushes of cotton.

The device comprises a brush guide 1 and successively arranged upper pair 2 of spindle drums, a pair of husking rollers 3, a separator in the form of a drum 4 with blades, part of the periphery of which is covered by a grid 5, and the lower pair 6 of spindle drums. Near each spindle drum pullers are installed 7. Under the mesh 5 there is a pitched board 8 for the removal of litter. The receiving chambers 9 and 10 are designed for separate cotton picking from the upper 2 and lower 6 pairs of spindle drums, respectively. The lower pair of 6 spindle drums is offset in the horizontal plane relative to the pair of peeling rollers 3 in the direction from the mesh 5.

The device operates as follows.

Cut bushes of cotton are fed into the bush 1, from where they enter the working slot of the upper Lara 2 spindle drums, where the fiber is collected from the opened boxes. The cotton from the spindles is removed by pullers 7 and dumped into the chamber 9 to collect cotton of the uncovered part of the crop. Further, the bushes fall into the working slit of the shelling rollers 3, which rotate at different peripheral speeds, which ensures crushing of the kuraka and stretching of the lobules in the crushed boxes. Blade drum 4, pulling the bushes of cotton on the separating grid 5. selects weed impurities from the bush mass, formed after processing the bushes with shelving rollers 3. The emitted litter on pitched board 8 falls to the ground. After that, the cotton bushes fall into the working slot of the lower pair of 6 spindle drums, which remove the remaining and kurak part of the cotton picking. Cotton from the spindles is removed by pullers 7 and dumped into the chamber 10, designed to collect kuraka part of the cotton crop.

The offset of the lower pair 6 of the spindle drums relative to the pair of peeling rollers 3 prevents the direct trapping of litter formed during peeling in the working slot of the lower pair and thereby improves the purity of the cotton part.

Claims (1)

Claim A device for collecting raw cotton from cut cotton bushes, containing horizontally installed upper and lower pairs of spindle drums and a pair of corrugated shearing rollers located between them, characterized in that, in order to reduce the contamination of wadding cotton, the device is equipped with a separator located between shelling rollers and the lower pair of spindle drums and a separating grid located in the form of a drum with blades and located to the side of it; the lower pair of spindle drums is shifted in horizontal plane relative to a pair of shelling rollers in the direction from the separating grid.
