Description

Cleaning machines, VC. A number of cylindrical drums arranged one above the other, covered with a fluffy cloth around the outer surface, are known.

In such machines, the cleaning of the fleecy fabric is done by wads, which quickly smooth down the pile and wear the fabric.

In order to clean the working surface of the drums from sticking oat grains without damaging the pile and the fabric, apply stringed ossifunders located under the drums to meet the movement, and an air duct with a longitudinal goal for the air flow directed along the movement of ov1-a.

FIG. 1 machine is shown on the side; in fig. 2-z longitudinal section.

Workers opiaHb; The mappings are made in the form of three cylindrical drums, 2, 3 with wooden outer surfaces covered with fleece fabric, for example cotton cloth. The drums are mounted on the sheer frame 4 one above the other at an angle of 65 ° with the displacement of the centers and driven in opposition; from the engine, and 1p transmission by means of belt and chain transmissions. Untreated grain is fed into the dumping box 1 of 6, mounted above the top drum /, buckets with a hopper 7 from the bunker 8. Movement; the warp on the top drum is regulated by a flap 9 installed by the front 15 of the backfill KOBHia 6. For a uniform grain across the whole the width of the drum in the charging bucket can be located auger, and from the outside of the KOBina on the exhaust shelf is installed a1.1SN power cable. A ribbed roller 1 (1.

In addition, under each drum there is an air duct 14 with a longitudinal axis I1, a spruce for air flow, right direction and movement of the drum in the area of oats discharge to igit 13.

Under each drum, there are 3--4 lamellar strings of a breach of riflegee 15, the tension of which is ensured by the corresponding accessories, eui my. Lamellar-strings clean the working surfaces of the baraba "n &% (cloth) from adhering oat and weed grains. When the machine is running, the flaws should not touch the surfaces of the drums to avoid fabric wear. Apart from the strings, the cleaning of the processed grain on the drums and centrifugal force contribute to cleaning the surfaces of the drums from dust. The rotation of the drums should be carried out along the grain with such a number of revolutions, so that the grain was carried along the drums by a layer that seemed to stick to them.

The factor that ensures the removal of oats from the grain is a high circumferential speed, which creates the necessary centrifugal force, which largely contributes to the improvement of cleaning. With a drum diameter of 600 mm and a length of 1400 mm, the best selection of oats from the grain is about 4000 kg of grain per hour.

Invention Draft

An ovines cleaning machine that includes a series of cylindrical drums arranged one above the other, wrapped around the outer surface with a fleecy fabric, is characterized in that, in order to clean the working surface of the drums from sticking oat grains, there are stunner blowers located under the drums to meet the movement and an air duct with a longitudinal slit for the air flow, directed downstream in the oversize zone.
