SU32089A1 - Rotary Decorticator - Google Patents

Description

The present invention relates to a rotary / decorticator with screw knives.

In FIG. 1 shows a section along line Afi in FIG. 2; FIG. 2 is a sectional view along the line CD in FIG. four; FIG. 3 is a side view of the decorticator; FIG. 4 view from above; FIG. 5-9 details of the decorticator; FIG. 10-scheme of its action.

The flax loaded into the hopper 24a is conveyed by the conveyor 28 in a bent position to the smooth rollers J3. The bending of the stems at an angle to the direction of movement of the conveyors is achieved by means of the main tracks, the spiders 29, having a lower speed. The smooth rollers (5) are passed, the stems are grabbed by the conveyors 8, under the action of a group of screw knives / 7,} 8. Each group of knives, consisting of three pieces, is arranged in such a way that the lower blade rotates on the shaft 40 in stationary bearings, and the two upper blades, located on both sides with respect to the lower one, rotate in bearings swinging around the shaft 19. These bearings are mounted on pins 46, with the springs 24 tending to lift the bearings, and the bolts 23 to 77

push them down. The entire system of screw knives rotates in the opposite direction to the direction of movement of the conveyors and is set in motion as follows. Shaft 40 of one of the knives has a larger diameter than all other blades; A pulley / is fitted on one end of the shaft (fig. 1, 4), and on the other is a bevel gear, resulting in rotation of the longitudinal shaft 42. The upper blades are driven by parasitic gears 43, 44 and 45. Gear 43 kr feed finger 46 and thus changing the position of the upper blades during adjustment does not affect the engagement of the spur gears.

To strengthen the knives 21 in the screw grooves of the drum 20, which sits on the shaft / P, serve as screws 22, which, with their tapered portion, clamp the knives in these grooves. The separation of waste from the processed flax is based on the fact that the knives, due to their screw structure, carry this waste from the middle of the machine to its edges, where they fall into the collecting bucket 52 and are picked up by conveyors 35, 37. The conveyor 37 is pivoted and its slope is adjusted by tension. cable 38 slung over

block 39, and in the working position it is fixed vertically.

Subject and z.

Claims (4)

1. A rotary, decorticator with helical knives, characterized therein, with the purpose of processing the original seed sticks carried by the conveyors 8 at an angle to the direction of movement of the conveyors (Figs. 1-4, 10), and then the ends of the stalks are six groups of screw knives 77- 75 rotating towards the direction of movement of the conveyors, the short-circuit of which the scissors one in each group rotates in the fixed bearings of the bed, the same two upper knives, located in each group on the sides of the lower blade, rotate in compliant around the axis of the lower knife bearings (Fig. 5, 6). 2. The form of a vypredaiz of a dekkorkator according to claim 1, is different the drive of both upper knives of the group serves as an intermediate gear 43, right on the finger 46 with gears 44--45 (Fig. 5, 6), on the finger of which gear 43 also has a bracket with pressure bolts 23 dl located in the earrings and spring-loaded 24 shaft bearings of the upper knives. 3.The form of the screw knife in the decorticator for l. 1, characterized in that for strengthening the grooves of the drum 20 (fchg. 7, 8, 9), which are screwed at a 45 ° angle of elevation, a scissors 27. Screws 22 with tapered unclamping heads are designed. 4. In the decorticator of claim 1, the use of a waste disposal device, consisting in that, in order to feed waste into the collecting bucket 52, mated with the outgoing conveyors 35 and 37 (Fig. 1-2), themselves hojiH viadoEye.
