Description

FIELD OF THE INVENTION The invention relates to agricultural machinery and mainly to machines for cleaning tobacco leaves from cut plants.

A device for separating tobacco leaves is known, which contains feeding working bodies, a separating mechanism, and conical shaped take-up rollers 1.

Closest to the present invention is a device for separating leaves from cut stalks of agricultural plants, comprising feed rollers, elastic brushes, against which a leaf separator mechanism is installed, and a drive mechanism 2.

A disadvantage of the known devices is damage to the stem and leaves during the movement of the leaf-separating mechanism.

The purpose of the invention is to reduce injury to the leaves. ,

This goal is achieved by the fact that in a device for separating leaves from cut stalks of agricultural plants containing feed rollers, elastic brushes, against which a leaf separator mechanism is installed, and a drive mechanism, the leaf separator mechanism is made of two pairs of mutually perpendicular in the working position flexible plates, installed with the possibility of forming cells of square section, by connecting both ends of each pair of plates with the drive mechanism, while the flexible plates have aggravation.

FIG. 1 shows schematically the proposed device for separating leaves, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2

The device for separating leaves from cut stalks of agricultural plants consists of two feed rollers 1, behind which elastic brushes 2 are installed. Against the latter there is a leaf-separating mechanism, made in the form of two pairs of mutually perpendicular flexible plates 3 with sharp blades, installed with formation in the working position of the square cells, by connecting both ends of each pair of plates 3 with the drive mechanism in the form of a rod 4 connected to the actuators in ide electromagnets 5, provided with return springs 6. The circuit 5 includes electromagnets switch 7 mounted in spring-receiving roller 8 by which the receiving drum is 9. Under the

On the sheet separator mechanism installed hopper 10.

A device for separating leaves from cut stalks of agricultural plants works as follows.

5 Pre-cut tobacco plants using feed rollers 1 are fed by the tip forward into the pickup rollers 8 and 9. The top of the plant, falling into the space between the pickup rollers, lifts the spring-loaded roller 8, which causes the contacts of the switch 7 to close, the electromagnets 5 are activated, and the flexible pairs of plates 3 arranged perpendicularly Relative to each other, thus forming a cell of a quadratic cross section. A stem grasped by the pickup rollers 8 and 9 is pulled through a square cell, and the point of the blades of the plates 3 cuts off the leaves from the stem. Elastic brushes 2 rotating in the opposite direction are guided. separated

0 leaves into the bunker 10. At the same time, the stem, freed from the leaves by the take-up rollers 8 and 9, is thrown out, the movable drum 8 is in the initial position, the contacts of the switch 7 are opened, the electromagnets 5 are de-energized 5. The plates 3 are compressed and form an ellipse-shaped space for the passage stalk The process then repeats.

The use of the proposed device Q allows to improve the quality of the process of separating the leaves from the stems by improving the design of the leaf-separating mechanism, which leads to an additional increase in labor productivity.
