SU30394A1 - Decorticator - Google Patents

Description

 The invention relates to decorticators with oppositely vibrating parallel or non-parallel knives and is intended to give a machine that / would have a small footprint and allow the processing of short-stemmed bast plants. In the proposed decorticator, two double-groups of oppositely vibrating knives are applied, which, as well as barbed stem propellers, are arranged symmetrically relative to the longitudinal axis of the decortator.

In FIG. 1. depicts a cross section of the decorticator and FIG. 2-part longitudinal section of it

The proposed decorticator has the following device. The stems to be processed by the L. cub plants, thrown into the funnel 25 (Fig. 2), are captured by the hardened advances 24, 24a installed in the frames. 231 23a, driven by eccentrics 22, shaft 27. As the frame

23,23a mates with eccentrics 22; then the movement paths of the propellers 24, 24a will be circumferential, with a diameter equal to the eccentricity, and the propellers will feed a layer when the eccentric shaft is rotated

57 .--

stems, equal to eccentricity, the thickness of the layer is regulated by a shield 26 (Fig. 2).

The stems, having passed the shield 26, fall under the movable oppositely vibrating knives b and 6a and the fixed knives 4, fixed to the frame, which inflict intense blows, but since the movable knives 6 to 6a work from cranks displaced by 90 °, the processed fiber gets hit lengths at different times.

The decorticator is set in motion as follows. Shchkiv 17 (Fig. 1), receiving rotation from an energy source, transmits rotation to a shaft on which gears / 5 and 15a sit, transmitting rotation through gears 14, 14a to shafts 13 75a on which eccentrics 11, 11a are fitted, with respect to eccentrics, 72a at an angle of 90 °. The eccentrics are driven by the moss. 9, 9a, 10, and 10a, and moving p; shy 5, 5a, 7, and 7a, which are connected to each other by columns. The fixed frame / and 2 are fixed to the old machine., On the shafts 75 and 13, a. the gears 79 are seated, transmitting rotation by means of gears 20 to eccentric shafts 27, resulting in turn
