Abstract

The invention relates to the primary treatment of bast fibers and improves the quality of the fiber by reducing the cutoff of the ends of the fibers and eliminating the possibility of winding. The drum consists of beats 1, mounted on the shaft 2 by means of discs and crosses 4. On the crossbars 4, fixed grates 5 with strips 6 are fixed. The slats 6 have a variable height increasing in the direction from the beat 1 to the shaft 2, and are located in the grating 5 with variable pitch, increasing in the direction from the beater 1 to the shaft 2. The height of the bars 6 is more than half the pitch between them. The proposed drum allows processing at increased speed conditions. I zp f-ly. 2 Il. (C (L with:

The invention relates to the primary processing of bast fibers.

The purpose of the invention is to improve the quality of the fiber by reducing the cut-off of the ends of the fibers and eliminating the possibility of winding.

Fig. 1 schematically shows a drum of a trowel for processing bast fibers; figure 2 - section aa in figure 1,

The drum of a trebler for treating bast fibers consists of beaters 1 mounted on shaft 2 by means of disks 3 and crosses 4. On crossings 4 podbilnye grids 5 with strips 6 are fixed. The slats 6 are arranged with variable pitch t, increasing in the direction from beater to shaft . The height of the slats also increases in the direction from the hammer to the shaft. At the same time, the height of the planks is greater than the step size of the method, i.e., 0.5 t.

The drum of the scutter for processing bast fibers operates as follows.

Washed material (raw) clamping conveyors is introduced into the treatment area. During the rotation of the drum beat 1 and slats 6 interact with bast fiber material, clearing it from fires. Sliding of bast fiber

The grid 5 provides for overlapping of the fiber behind the strips 6, which excludes the possibility of drawing and cutting off the ends of the fiber, so 5b (Fig.2), and creates the necessary conditions for its processing.

The use of the proposed drum of the trelling machine for the processing of bast - JQ fibers allows the fiber to be processed at higher speeds, which improves the throughput of raw materials and improves the quality of the fiber produced.
