The invention relates to the primary processing of bast fiber material, in particular to the cleaning of bast fiber material.

The purpose of the invention is to increase productivity.

A third of a pair of discs are mounted on the pulley AND the presser belt 4 on both sides.

There is a means for cleaning the fibrous material with air jets 5, containing a high-pressure fan 6, duct 7, manifold 8 with pipes 9 installed above 25 lower working branch of the pressure conveyor A. The pipes 9 have holes for air jets to expire in a direction transverse to the movement of -Erricentric 10 along the upper working branch of the conveyor 3 means dp of holding material 3. Since the conveyor 3 is single-lined, the free ends of the material being processed are ecologically transferred by the action of inertial forces into rtikalnoy planes that facilitates removal of the mother ala fibrous impurities that

The device works as follows.

Stem material, for example, flaxing from rolls or in sheaves with loose tails, is guided into the area between the first pair of toothed disks 1 and table 2. The teeth of these disks are partially pierced by a layer of stems and propel it to the pre-loosening and leveling unit. The tooth of the second pair of disks 1 captures a certain portion of the stems and as a result of the fact that the rotational speed of the second pair of disks is greater than the first, as well as the number of teeth, loosening occurs, the layer of material is flattened in thickness and cleaned. Some of the non-fibrous impurities fall out of the fibrous material and through holes in the table 2 are carried to the lower cover (dust collector) 13. As the

material, the stems are grabbed by the tooth, t of the third pair of disks 1, which

the rotational speed and the number of teeth are larger than those of the disks of the second pair 1, therefore, loosening, cleaning and final leveling of the fibrous material in thickness is performed. A third of a pair of discs are mounted on the pulley AND the presser belt 4 on both sides. The stem material, the exit from the control of the teeth of the third pair of discs, is clamped in the middle by the belts of the pressure conveyor and conveyor 3 of the material retention means 3. The material fixed by the ribbons is subjected to shaking, which is ensured by the impact of the eccentric 10 along the upper working branch of the conveyor 3 means retention of material 3. Since the conveyors 3 are single-lined, the free ends of the material being processed vigorously move under the action of inertial forces in a vertical plane. -plane, thereby removing impurities from fibrous material which

Carry to upper dust dryer 12

and the bottom dust receptacle 13. After passing through the area of mechanical cleaning, the fibrous material gets into the area of aerodynamic processing carried out by means of air cleaning

5 By the action of jets of air flowing out of the holes of the pipes 9 at high speed, the remaining weed (non-fibrous) impurities on the surface of the material stems are carried away and the lower dust receptacle 13. Subsequently, the cleaned fibrous material leaves the clamp between the conveyor belts and enters the tray 15, from which falls on the conveyor 16, transferring it to further technological processing by the machines for preprocessing bast fibers.

Due to the kinematic connection, the linear velocities of the material under the third

a pair of toothed disks 1 and conveyor 3 means for holding material 3 are equal, which ensures uniform material progression, except for the layer gap.
