Description

(54) APPARATUS FOR SEPARATION OF TOBACCO LEAVES

I

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to tobacco-harvesting machines.

The invention can be used on a machine (combine) designed for ordinary tobacco harvesting with an ordered orientation of the leaves.

A known apparatus for separating tobacco leaves, provided with leaf-oriented sh, e-reels, a clamping conveyor and a leaf separator 1.

A disadvantage of the known apparatus is that when the turgor decreases (in hot weather), the tobacco leaves lose elasticity and, because of this, at the exit of the brush drums fall between the end surface of the lower drum and the clamping conveyor, clogging the input 15 shed conveyor and thus violating the process.

The purpose of the invention is to reduce the clogging of the leaves of the entry shed clamping conveyor.

This goal is achieved by the fact that the lower front drum of the clamping conveyor is equipped with jacking fingers and is mounted relative to the upper front roller.

a drum with a gap, the size of which increases the length of the jacking fingers, while the conveyor belt is made with an elastic material, for example, foam plastic.

The drawing shows the proposed device, side view.

Claims (1)

The apparatus includes a pair of belt-oriented brush drums 1, a clamping conveyor 2, made in the form of two sections of narrow-belt conveyors with working branches in contact with one another, and a sheet splitter 3 made in the form of paired serrated knives. In this case, the entrance shed of the clamping conveyor 2 is located at the exit of the sheet-oriented brush drums 1, and the separator 3 is located on the side of the clamping conveyor 2 on the side of the working channel between the input and output sheds. The lower front drum 4 of the input shed clamping conveyor 2 is provided with bogie fingers 5 and is set relative to the upper front drum 6 with a gap, the value of which exceeds the length of the bogie fingers. The conveyor belt 2 is made with an elastic material, such as foam. The device works as follows. When the tobacco-picking machine is operating, the leaves of the collection tree are diluted with leaf-oriented brush drums 1 to the side of the working channel along which the plant stems move. When exiting from the sheet-oriented brush drums 1, leaves with a small turgor are drawn into the gap between the lower front drum 4 of the clamping conveyor 2 and the brush drum 1. However, jacking fingers 5 are pushed out of this gap and fed through the entrance shed into the clamping conveyor 2, which holds the leaves during cutting with knives, separators 3, and then delivers into an external vertically disposed conveyor. For the assembly of leaves from one row, two mirror-made apparatus are used simultaneously. The application of this invention allowed us to obtain a high coefficient of reliability of the technological process (0,%) performed by a KTH-16 tobacco harvester. At the same time, the annual economic efficiency from the use of this combine amounted to 3191 rubles. Claims An apparatus for separating tobacco leaves, comprising leaf-guiding brush drums, a clamping conveyor and a leaf trap, characterized in that, in order to reduce clogging of the leaves of the entry shed of the clamping conveyor, its lower front drum is provided with bogie fingers and is mounted relative to the upper front drum with a gap, the value of which exceeds the length of the jacking fingers, while the conveyor leite is made with an elastic material, such as foam plastic.
