Abstract

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Roller threshing device for threshing flax fiber strip contains upper and lower support rubberized rollers and spring-loaded self-centering presser mechanism of the upper rollers. Upper rubberized rollers are combined with a clamping, endless rubber band. Lower support rubber rollers are also combined with their endless rubberized belt. Between the upper and lower rubber-coated rollers are mounted intermediate rubberized spring loaded upper and lower vibrating rollers.

EFFECT: roller threshing device allows to activate the process of seed separation from the flax fiber tape and to reduce seed losses.

Description

The invention relates to the field of agriculture, in particular, can be used in the design of mobile and stationary devices for threshing flax flax, as well as cereals and legumes.

Known threshing device of the picker-stripper of flax tapes (Utility model Belarus No. 5583) containing a clamping conveyor and stripping drums, while the drums are notched and installed at an acute angle to the clamping conveyor.

The disadvantage of this device is the presence of a dead zone between the clamping conveyor and threshing rollers.

A flax thresher is known (USSR Patent No. 17894), containing two pressure drums mounted perpendicular to each other, while the bearings of the upper roller are mounted movably in order to influence the flax heads with the weight of the drum.

The disadvantage of this device is the need for manual labor to direct the stems between the rollers, as well as the need to repeat this operation from 2 to 5 times for complete threshing of the sheaf.

The closest, in technical essence, to the claimed device is a five-roll threshing device of flax tapes (RF Patent No. 2597979) containing rubberized rollers, a spring-loaded self-centering pressure mechanism and nozzles, while the two upper rubber rollers are combined by one pressure endless rubberized tape, and the three lower rubberized rollers combined by another clamping endless rubberized tape; both clamped rubberized endless tapes are in the same plane with the working surface of the rubberized rollers, in their central part, one above the other, and have spring-loaded tension mechanisms.

The disadvantages of this design are the violation of the technological process of threshing at high speeds of the belt between the rollers, losses due to the removal of seeds from the threshing device along with the belt, and loss of seeds remaining in the flakes of the bolls as a result of their removal outside the thresher by air flow.

The objective of the invention is to exclude the possibility of disrupting the technological process of threshing at high speeds of movement of the tape between the rollers, to activate the process of separating seeds from the tape and to prevent loss of seeds remaining in the flakes of the boxes due to their removal outside the thresher by air flow.

This goal is achieved by the fact that according to this invention, at least a five-threshing threshing device for threshing flax flax tape containing upper rubberized rollers combined by a pressure endless rubber tape, a spring-loaded self-centering pressure mechanism of the upper rollers, lower supporting rubberized rollers combined by an endless cutter the fact that between the upper and lower rubberized rollers installed intermediate rubberized spring-loaded upper lower vibrating rollers are equipped with a guide.

In FIG. 1 is a side view of a roller threshing device, and FIG. 2 is a plan view.

The figure 1 shows: the lower rollers - 1; upper rollers - 3; pressure endless rubberized tapes - 4 and 8; spring-loaded self-centering clamping mechanism - 2; intermediate spring-loaded rubberized upper and lower vibrating rollers - 5, 6; guides of the upper and lower intermediate rollers - 7; a collection of seed heaps - 9. In addition, figure 1 shows a ribbon of flax-10 flax.

The device works in this way: from the tape-forming table (not shown in the figures) an unfrozen flax-flax tape 10 is fed. Between the upper rubberized roller 3 and the lower rubberized rollers 1, the flax-tape 10 is exposed to a spring-loaded self-centering pressing mechanism - 2. When moving from the first lower rubberized roller 1 to the second, the flax ribbon 10 is pressed against the lower surfaces of the upper rubberized rollers 3 by the pressure endless rubberized tape 8, while the impact on the tape 10 There is an intermediate spring-loaded rubberized lower vibrating roller 5, and the selected seeds from the tape 10 are spilled into the seed pile 9 collection, from where they are sent for further processing. With further movement of the tape from the first upper rubberized roller 3 to the second, the linen 10 is pressed against the upper surfaces of the lower rubberized rollers 1 by the pressure endless rubberized tape 4, while the intermediate spring-loaded rubberized upper roller 6 has an additional effect on it. During threshing, long flax tape 10 is permanently firmly fixed between rubberized tapes and intermediate spring-loaded rubberized upper and lower vibrating rollers - 5, 6, reliably fixed guides of the upper and lower intermediate rollers - 7, and makes zigzag movements, moving along a path that goes around the rubberized rollers, which contributes to the process of separation of seeds from it under the action of vibration, inertia and gravity.

Using the inventive device allows thrashing flax flax bolls without disturbing the process at high speeds of the belt between the rollers, activating the process of separating seeds from the tape and preventing the loss of seeds remaining in the flakes of the bolls due to their removal from the thresher by air flow.
