Description

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in flax harvesting machines.

The aim of the invention is to improve the reliability of the flax harvesting process, reduce seed loss and simplify the design.

Figure 1 shows a flax harvester, side view; on figure 2 - the same, top view; Fig, 3 - section aa in Fig.2.

The flax harvester contains front-lifting devices 1, devices 2 for transferring the stems, clamping conveyors 3, stripping drum 4, conveyor pile 5, bunker 6 for pile and spreading devices 7. All working parts are mounted on chassis 8.

The 2dl stalk transfer devices consist of half-cross fingers 9 of the belts 9 and a screw-like attachment 10 located parallel to the working surfaces of the finger belts 9, and are installed with a gap, forming a channel for the passage of the ribbon of stalks.

The spreading devices 7 have a device similar to the devices 2 for transmitting the stems. The scraping drum 4 is located between the clamping conveyors 3 intertwined with each other, above the pile conveyor 5. The axles 11 of the pulleys of the clamping conveyors 3 are parallel and inclined at an angle to the pile conveyor 5. From the top of the tows, the drum 4 is covered with a stripper chamber 12, and from the bottom - pallet 13. Stripping drum 4, has disks 14 with two-shoulder combs mounted on them, assembled on wasps x 1: 5, Combs have shoulders 16 and 17, On disks 14 of drum 4, in zones (free from the influence of shoulders

16 and 17 ridges, fixed support. elements so that their working surfaces are at a maximum distance R from the axis of the drum 4, smaller than the radius R of the circumference of the axes 15 of the shoulders 16 and 17 of the ridges.

In the particular case, the supporting elements for the stems are made in the form of rollers 18 fixed to the disks 14 of the drum 4 by means of axles 19 placed in rolling bearings. For Better rotation of the support rollers 18 when it is in contact with the stalks, the outer surfaces of the rollers 18 can be coated with friction material.

Flax harvester works as follows.

When the machine moves forward, the flax stalks enter the streams of the frontal topping devices 1. Worn out stems arrive at the devices 2 for transferring the stems from the lifting devices 1, where during transportation with half-fold finger belts 9 through the helical channels bounded by the screw-shaped strips of 10, they are deployed by spiral-shaped finger belts 9 through helical channels bounded by the screw-shaped strips of 10, deployed by spiral-shaped finger belts 9 through helical channels limited by the screw-shaped direction of stripe 10, they are deployed by means of helical channels 9, which are bounded by the screw-shaped direction of stripe 10, which are rotated by means of helical channels 9 that are limited by the screw-shaped direction of stripe 10, they are rotated by means of helical channels 9, which are bounded by the screw-shaped direction of stripe 10, which are rotated by means of helical channels 9 that are limited by the screw-shaped direction of stripe 10, they are turned by means of spiral-shaped finger belts 9 which rotate along helical channels limited by the screw-shaped direction of stripe 10 and turn into 10 spiral lines. towards each other and fed into the inclined clamping conveyors 3. The clamping conveyors 3 flax stalks are introduced into the compartment angle 12, where they are affected by the arms 16 and 17 stripping drum 4. When this is done, the seed boxes are peeled off the shoulders of the I6 ridges from the left along the technological process, and the ridges of the ridges 17 are stripped from the right tape 17. The waste products (heap of flax) fall down the nl conveyor of heap 5, which is diverted to the bunker 6 for their collection. The stripped strips of the stems are withdrawn by the clamping conveyors 3 from the chamber of the tow 12 and are fed to the spreading device Hbie 7, with which the spread-.
