SU1409213A1 - Arrangement for cleaning tobacco leaves - Google Patents

Abstract

The invention relates to the field of agriculture, in particular, to devices for cleaning tobacco leaves from pharmacy, dust and impurities. The aim of the invention is to increase the productivity and quality of cleaning by preventing the leaves from sticking to the sieve holes. The sieve has holes 12 arranged longitudinally and having an oval shape. On the surface of the sieve, protrusions 13 are made adjacent to the front of the holes and located at an acute angle to the surface of the sieve. The sheet located on the surface of the protrusions 13 does not block the opening 12 during the movement, as a result of which the suction is provided from the entire lower surface of the sheet and free movement of the leaves along the sieve. 2 Il. with (L

WITH

Isothery refers to agriculture, in particular to devices for cleaning tobacco leaves from pharmaceuticals, goods, and impurities.

The aim of the invention is to increase the productivity and quality of cleaning by preventing the leaves from sticking to the sieve holes.

FIG. 1 shows the proposed device; in fig. 2 - a sieve with holes and protrusions.

The device is a frame 1 on which a vibrodrive is placed, including an electric motor 2 connected to the drive shaft 3 by a belt drive 4, an eccentric 5 and a pusher 6. The box 7 is mounted on flexible rods 8. Inside the box 7 is placed a sieve 9 with clip and an air vent 11, connected to the exhaust ventilation of the room for suction from under the sieve of the pharmacy, dust and impurities.

The sieve 9 has holes 12, arranged longitudinally and having an oval shape. On the surface of the sieve, protrusions 13 are made adjacent to the front part of the holes 12 and located at an acute angle to the surface of the sieve so that their tops are directed against the course of movement of the tobacco leaves.

The device works as follows

From the electric motor 2 through the belt drive 4, the rotation is connected to the drive shaft 3, on which the eccentric 5 is fixed. The eccentric 5 converts the rotational movement of the shaft 3 to the reciprocating movement of the duct through the pusher 6.

Leaves are moved to the sieve, moving down under the action of vibration.

A floor space is created using an air inlet 1I to create a rarefied space where the pharmacy, drums and impurities are drawn out through the openings 12 The sheet, which is constantly on the surfaces of the projections 13, does not block the openings 12 during movement, resulting in a suction leaf and free movement of leaves on the sieve.

After the sheet has disappeared from the surface of the protrusion 13, suction is also carried out from the upper surface of the sheet through the opening formed by the base in the mortar. From sieve 9, the cleaned leaves are fed to the belt 10, from where they are dumped to the sorting TparitnopTep (not shown).

The proposed device provides high-quality cleaning, since suction is performed from the leaf surface, which is not limited by the size of the holes.

Claims (1)

Invention Formula A device for cleaning tobacco leaves, containing a duct inclined mounted on a frame by means of flexible tg, a sieve with longitudinally located oval holes placed in a duct, and a vibration drive, so that, in order to increase the productivity and quality of cleaning preventing the leaves from sticking to the sieve holes, protrusions are made on the surface of the latter, adjacent to the front part of the holes and located at an acute angle to the sieve surface so that their tops are directed opposite to the movement Yeni tobacco leaves.  . b 2 . b 2 fig f
