Description

54} DEVICE FOR POLYTIC CLEANING OF TOBACCO

one

This invention relates to the mechanization of agriculture and can be used for the development of tobacco harvesting machines.

A device for sheet-cleaning tobacco is known, comprising successively mounted on the frame a sheet-oriented and leaf-separating mechanisms, feed and receiving conveyors made in the form of contacting tapes installed one above the other, the upper and lower s of which have common intermediate shafts, and sheet-fastening; exaItpz

In the H3BecfHOM device, however, at the time of compaction, the leaves are damaged due to the friction of the transport feed branches moving at a higher speed than the speed of the sheet in the accumulation zone.

The purpose of the invention is to reduce damage to the leaves in their compaction.

This is achieved by the fact that the device for sheet cleaning of tobacco is fitted ustaned on a common intermediate shaft upper drum with Elastic

 mi fingers and | set under it

: removable comb with tooth

. wife between the fingers of the drum.

: Drawing shows the proposed

device in two projections. : Each section has a sheet-orienting mechanism consisting of drums.

1 Vj 2, a feeding conveyor with ribbons i 3 and 4, a leaf separating mechanism, including a supporting conveyor 5, a disk knife 6 and a stopper 7, a baraba 8 equipped with elastic fingers,

: comb 9, stop 1O, sheet fastening mechanism 11, receiving conveyor with

: tapes 12 and 13.

When the device is working, tobacco plants enter between the sections of the working bodies. The counter-rotating drums 1 feed the leaves to the drums 2, which.

oriented diluted to the side of radka plants. Divorced to the sides

leaves are grabbed by ribbons 3 and 4 of the delivery conveyor and held by them; when they are separated from the stalk and tampered with disc knives 6.

the conveyor 5 and the stopper 7 limit the zone of contact 4er of the skull part of the leaves with the disk knife 6.

By moving the leaves, they are stretched with elastic fingers of the drums 8 and advance them under the comb 9. After meeting with the elastic fingers of the drum 8 advancing the sheet with the stop 1O, the ends of the fingers move away from the leaves in the direction opposite to the direction of leaf movement and at the same time lifting Crowding up, the exit from the leaf advance zone under the comb 9. Thus, at the moment of encounter with the fixed support 10, the elastic / fingers of the drum 8 on the sheet cease to function, and their exit from the leaf advance zone is carried out without friction. leaves After exiting the combs, the leaves 9 enter the receiving conveyor and, clamping it with ribbons 12 and 13, are fed to the sheet

mechanism 11, and then the output devices mounted on mpvyi,
