Description

The invention relates to the mechanization of agriculture, in particular to devices for the post-harvest processing of tobacco.

A device for laying tobacco leaves on a conveyor of a tobacco-pressing machine is known, which comprises a stacker in the form of a set of disks with needles, gripping and feeding from a cassette oriented leaves onto a conveyor belt.

It is also known a device for separating the leaf weight of tobacco leaves, containing an air duct, performing a leaf separation process, and a divider that evenly distributes the leaves across the width of the receiving conveyor.

A disadvantage of the known devices is the impossibility of laying on the receiving device uniquely oriented (with the petioles in one direction) tobacco leaves from a mass of chaotically piled leaves.

The purpose of the invention is to increase the functionality by providing oriented leaf laying.

The proposed device improves the quality of separation of leaves from the mass of chaotically loaded onto the feeder, performs orientation along the central vein and along the petioles and laying oriented leaves on the conveyor of the embroidery machine with a given pitch.

The goal is achieved by the fact that a device for a sheet-dividing mass of tobacco leaves, containing an air duct, consisting of horizontal and inclined parts and communicating with a pressure fan, and a discharge conveyor, at the entrance end of the inclined part of the duct, communicated with a blower fan and having a double-bent surface with inclined nozzles in the direction of air flow, the device is equipped with an additional inclined chute, false discharge between the casing and conductive conveyor, and two vertical partitions (reflectors), one of which is mounted over the additional launder and the other - over the conductive discharge conveyor.

FIG. 1 shows a diagram of the proposed device; in fig. 2 - orientation scheme.

A device for the sheet separation of the mass of tobacco leaves contains a duct 1 with an injection fan 2, a feed conveyor 3 located above the receiving window 4 of the duct, inclined concave channels 5 and 6 mounted behind the duct, a box 7 with partitions (reflector) 8 mounted between the grooves 5 and 6 and made in the form of a double-bent surface, blown through an inclined nozzle 9 by an injection fan 10, and a partition (reflector) 11, located above the discharge conveyor 12 behind the groove 6.

0 The device works as follows.

Worn out or freshly harvested tobacco leaves are poured onto a falling conveyor 3 in several layers, which

5 moves them and drops them through the receiving window 4 into duct 1. In the latter, a bundle of leaves is picked up by the air flow blown by fan 2 and moves to the inclined chute 5.

In the duct, as a result of a collision with the walls, a splitting occurs on single leaves, which then enter the inclined chute 5. In channel 5, single leaves in a relatively weak air flow, creating an air cushion along the lower concave surface, are oriented by a central core along the direction of movement stems forward or backward. Then

0 the sheet falls on the double-curved surface of the box 7 and, maintaining the speed of movement in the air flow created on the surface of the box through the inclined nozzles 9 by the fan 8, flies out of its limits

5 along a path that in a certain section is a continuation of the curve along which the surface of the box is outlined.

Outside the box, under the action of the force of the sheet, the sheet deviates from the specified

0 surface box trajectory. When the leaf moves by the scape forward, due to the location of the center of sheet metal closer to the scape, the latter is lowered (Fig. 2), and the air flows lift the end of the leaf, turning it (counterclockwise). Then the sheet is tilted down by the scapula, removed from the partition (reflector) 8 and falls vertically into the inclined chute 6. When the sheet is moved by the stalk, back the end of the sheet to

When the stem is outside the box, it moves along a predetermined path, after the stem leaves the box, the latter is lowered, turning the sheet clockwise. The air flow presses the flat sheet to

5 surface obstacles. Then the leaf slides (falls) with the stem on the gutter 6.

In the process of orientation outside the box, the sheet may be tilted relative to the direction of movement. This slope is eliminated when moving in chute 6. Departure beyond chute 6 leaves fall with petioles on the surface of the partition (reflector) 11, bounce and fall flat on the outlet conveyor 12 residential perpendicular to the movement of the conveyor.
