Description

 The proposed decorticator means processing the fiber evenly along the entire length using a system of fixed grates located under the systems of vibrating plates.

In the schematic drawing of FIG. 1 depicts a view of the proposed device in longitudinal section; FIG. 2 - side view.

The proposed decorticator consists of two beds /, fastened with transverse beams. A frame 2 with stationary knives is attached to the beveled surfaces of these beds. Inside the frame are movable frames of 3 t. 4 with vibrating plates 5 and 4 t. decorticator conveyors.

The device driving the frames and conveyors is as follows. On a short roller 5, fitted with a driving pulley, sprockets 5 and 7 are fitted, through which the chains 8 TA are thrown. 9 m sprockets W, 11 on shafts 72 and 13. These shafts rotate in ball bearings fixed in beds. The ends of the shafts have eccentric undercuts / on which rods 15 are put. The second ends of these rods are hingedly fastened to the moving frames 3, 4, which, due to the displacement of the recesses 14 by the amount

84)

angles, make an oscillatory motion, and their middle also moves in the direction of stationary knives. The rods 76 in the guides 77 attached to the frame are hinged to the middle of the moving frames. Thus, the gravity of the moving frames is transmitted to the guides, which at the same time prevent them from lateral movement, as a result of which the frame, besides oscillatory movement, performs more and progressive, and the movement of both frames occurs with some delay, the size of which depends from the angle of displacement eccentric to the points 14 on the shafts. .

Flax transport, i.e. loading it, moving along the working part and unloading is performed by a chain conveyor with forks bb, by which the material is transferred through the machine at a certain speed. Movement. The transporter receives from the roller 5, on which a stepped pulley 18 is attached, connected by a belt with a pulley 7P, from which the transmission goes to the chain conveyor and to the transverse belt, which carries the campfire broken off by the knives to the side. The iron shield 26 separates the month: then the processing of flax from the drive mechanism, and to completely remove the fires that have settled on its surface, it is equipped with a vibrating spring 21. The proposed device operates as follows. Flax, the entrance to the first preparatory part, knives are subjected to preliminary wood breaking, in the middle part there is moth and in the last (output) final mint with. by simultaneously twisting the fiber through the edges of the stationary knives to separate campfires. The stroke of the knives is controlled by the possibility of changing the eccentricity of the recesses 14 on the drive shafts / 2 and J3. The machine is loaded from the table 23, from the slots of which the forks of the conveyor 22 continuously exit and carry the flax with an even layer to the knife mechanism. The forks of the conveyor 24, the exit between the stationary knives, capture flax and thus, without interfering with the operation of the knives, cause it to slide along the plane of the stationary knives. Having passed the working part, the flax fiber gets on the conveyor 25, which continuously carries it. The kocTpa is beaten off, the pad between the stationary, gets either directly onto the belt 26 and is carried to the side or settles onto the shield 20, from which, due to its slope and vibration, is also dumped onto the belt 26. Thanks to the gradation of the pulleys 18 and / 5, the flax feed rate can be adjusted from 4 to 10 lg. The speed of the conveyors is determined by the quality of the processed flax, i.e. the number of blows you need to give flax of this quality to get fiber. The subject matter of the invention. Decorticator for stems of bast plants with the use of two systems of incandescent plates differing in the use of the system of fixed grates aa (Fig. 1-2), located below the systems of vibrating plates 3-4 and serving to support the stems moved along the grates when they are moth conveyor with bb forks entering between the grate bars.
