Bast crops processing line

Abstract

The invention relates to an apparatus for primary processing of bast-fiber crops and can be used to obtain the same type straw fibers and shives or flax and hemp fibers. The bast crops processing line consists of the sequentially installed recoiling machine, dividing and scutching machine, breaking machine, the machine for scutching raw fibers without pressing tow shaker and shive-fiber waste transportation system, while the latter is fitted with a crushing device. The dividing and scutching machine makes it possible to form a layer of raw material with a definite and optimal density for processing, to card and separate shives from fibers. The machine for scutching raw fibers without pressing provides an intensive separation of shives from fibers, considerably facilitating further separation of free shives in the tow shaker. The crushing device improves reliability of the chive-fiber waste transportation system.

What is claimed is: 
     
         1 . A bast crops processing line, comprising: a recoiling machine, a breaking machine, a tow shaker and a chive-fiber waste transportation system, wherein after the recoiling machine a layer-forming and scutching machine is installed and a machine for scutching raw fibers without pressing is installed after the breaking machine, with the layer-forming and scutching machine, the breaking machine and the tow shaker are able to remove free shiver and each being connected directly to the chive-fiber waste transportation system; wherein the machine for scutching raw fibers without pressing is equipped with a static stator and a rotor with rotating blades, with the rotor and the stator of the machine for scutching raw fibers without pressing, when interacting, break long bast fiber complexes into shorter ones and create an air stream used to transport raw fibers from the breaking machine to the tow shaker, and the chive-fiber waste transportation system is equipped with a crushing device installed under the layer-forming and scutching machine.
