The invention relates to the processing of fibrous materials, can be used in machines for removing campfires from scraping materials by wiping fiber, and can be used in flax plants for the primary processing of flax and hemp.

The purpose of the invention is to increase the cleaning efficiency of bast fiber material from fires.

FIG. 1 shows the proposed device, a cross-section; in fig. 2 - the same, top view; in fig. 3 - the same view from the end of the shaft; in fig. 4 - beat, top view.

In the upper part of FIG. Figure 2 shows the position of the grate bars and rings with beams in a position perpendicular to the longitudinal axis of the shafts, in the lower part of FIG. 2 - rings with beams and grates in position at an angle to the longitudinal axis of the shafts.

A device for cleaning a fibrous material contains a fiber-receiving box 1, longitudinal shafts. 2, housed in housing 3, terminating in a cost-receiving bunker 4 with an outlet fitting 5. In the upper part of the housing 3 are installed longitudinal plates 6 and 7 with grate 8, fixed to longitudinal plates 6 and 7 by hinges 9. Plast-1 to 7 is installed in the housing 3 is fixed and plate 6 is longitudinally displaceable. On the shafts 2 there are mounted bushes 10, to which the hinges 11 fasten the rings 12 with strips 13. The means for changing the angle of inclination of the rings are made as follows. In the rings 12 there are holes 14 through which the ha 15 passes, connected to the rings 12 by the hinges 16.

The device works as follows.

The scraping waste containing fiber and campfire in the mixture enters the fiber receiving box 1 and is held in it by grate bars 8.

When the shafts 2 with billes 13 rotate, the latter, through the gaps between the plates 6, act on the material being processed, with the free fire falling into the receiving hopper 4, then being brought out into the pneumatic transport system through the outlet nozzle 5. fiber layer and throw it on the grate 8, located opposite, where at this time the phase of rotation of the blade is recessed, are located below the level of the grate 8. Since the rotation of the shafts 2 is interconnected, then The turning phase of the rotation of the left-hand blade will be recessed below the level of the strips 8 and the right-hand beats transfer the fiber to the left side of the fiber-receiving box 1. Such an impact is ensured by the fact that they are bent along an unwinding spiral curve.

In order to ensure that the material 12 is driven longitudinally along the shafts 2, the rings 12 with the strips 13 are rotated at an angle to the shafts 2 when being adjusted, by means of the pulls 15 are kept constant in this position. In this case, the beater 13 starts to receive, in addition to the rotational movement relative to the shaft 2, a screw movement, due to which the material moves forward, similarly to the movement of the material when the screw auger rotates. The speed of movement of the material depends on

the angle of rotation of the rings 12 and the frequency of rotation of the shafts. The pushes beat 13 to the side along the shafts and the fire was additionally removed from the fiber.

When adjusting the position of the rings 12, it is envisaged that the grate bars 8 are rotated by displacing the plate 6 relative to the fixed plate 7, in which the bar 8 is pivotally fixed in the fixings in the working position.

5 When using the proposed device, effective fires are removed from the bast fiber material by screw movement of the blows and positioning them on the shafts with a radial phase shift for shaking.
