FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to machines for flax harvesting.

The aim of the invention is to reduce damage to the stems and increase the reliability of the process during the transportation of products with air flow.

FIG. 1 shows a flax harvester, a slit perpendicular to the axis of rotation of the drum; FIG. 2 is a view A of FIG. 1i in FIG. 3 is a view of a comb of a combing drum with an air-permeable blade fixed on it.

The flax harvester contains a lifting machine 1, a camera 2 tows with a schoon and a combing drum 3 placed in it with ridges 4 on which blades 5 are fixed, a clamping conveyor 6 located above the axis of rotation of the drum 3, a pneumatic conveyor with a fan 7 and injecting the air duct 8, the spreading device 9 or the device for forming and viscous the packages installed instead of the removable spreading device 9. All the components of the combine are fixed on the frame 10 and the case 1 1.

The luggage compartment 2 includes a rear wall 12 and 13. The lance 13 has a hinge 14 and a latch 15 for connection with the chamber 2 ética in the lower (operating) position. The crests 4 are mounted in the disks 16, which are rigidly mounted on the shaft 17 of the drum 3, located horizontally in the support bearings 18 placed on the frame 10. The cranks 19 are rigidly connected at one end to the shafts 20 of the crests 4, and

breathable. The blades 5, having been freed from the tow products, practically do not create air flow in this part of the camera of the tow 2, as air is throttled between the teeth of the ridges 4 and the blade grille 5. The tow products through the duct 8 are carried by the air flow into the pile collection container. Zil.

others are mounted in bearings placed in a guide disk 21 supported by an eccentric 22. For driving the combing drum 3, an asterisk 23 and an overrunning clutch 24 are provided on its shaft 17. Such a device provides for translational circular motion of combing comb 3 4.

changes in the inclination of the ridges 4 with the eccentric 22 mounted rotatably on the shaft 17 are pivotally connected with screws of ha ha 25. The blades 5 of the ridges 4 are made

breathable, for example in the form of a lattice.

The walls 26 and 27 of the pallet of the chamber 2 of the nozzle form an ejector connected to the discharge duct 8 of the pneumatic conveyor. On the outlet of the delivery duct 8, a switchboard 28 is installed (the mechanism for controlling the position of the shield 28 is not shown). Flax harvester working

in the following way.

The flax stalks from the top-lifting apparatus 1 come in the form of a continuous tape into the clamping conveyor 6, by which it moves through the chamber: tow. Due to the fact that the clamping conveyor 6 is located above the axis of rotation of the drum 3, the tape of the stems passes from above the combing drum 3 and is pressed against its crests under the action of its own weight and elasticity of the stems in the tape, as well as the penetration of the teeth of the crests 4 into the tape stems going on

and at the expense of their sweeping up during the circular motion. As a result of the interaction of teeth

31

the ridges 4 of the combing drum 3 with the tape are stripped from the stems of the interchangeable boxes.

In the process of stripping, the upper zone of the belt is subjected to intense vibration due to the impact interaction of the teeth of the ridges 4 and their vertical accelerations during the forward-circular motion and machine work on the microrovelities of the field. The vibration forces contribute to a better release of free seeds and seed pods in the tape, which prevents their removal from the chamber by stripping the tape with stalks. Removing them from the tape is improved by adding forces to the weight of these particles and the created vacuum in the chamber 2 by drawing air through the jaw from it. The air tray in the discharge duct 8 is created by the fan 7.

One part of the free seeds and seed boxes, which are formed during the weaning, immediately spills down the nozzle chamber onto her pallet, made in the form of an ejector, and enters the discharge duct 8 through it. Another part of the free seeds and seed boxes together with scraps of stalks and the weeds are forcibly moved to the pallet of the chamber 2 of the nozzle in its upper part with the ridges 4, and in the lower part with the air-permeable blades 5 made, for example, in the form of a lattice. Throwing the nozzle products into the ejector connected to the discharge duct 8, the ridges 4 s lo pastes 5 go upwards due to their circular motion. At the same time, the air-permeable blades 5, having freed themselves from the products of towing, almost do not create airflow in this part of the combining chamber, since air is throttled between the teeth of the ridges 4 and the locking grill 5. To reduce the throttling effect, the grid area should be as low as possible. less than the rest of the blade area 5. As a result, no towing products occur in the towing chamber 2 from the rear wall 12. The tow products in the air duct 8 are carried by air

flow into the tank to collect the heap. The distribution of the pile along the length of the container is carried out by changing the position of the distribution board 28. With the optimum inclination of the teeth of the ridges 4, the eccentric 22 on the shaft 17 is rotated with a screw pull 25.

The stripped stalk ribbon is taken out of the camera 2 by the clamping tran- fO by the spider 6 and is fed to the spreading device 9, which is spread across the field. When replacing the spreading device 9 with a device for forming and binding packages, the ribbon of stalks is last formed and tied into packages dropped on the field.

Due to the fact that in the blade device of the fan wheel 7 not 20 are in contact with the stripped tape of the stems, damage to the stems is also excluded. The frequency of rotation of the fan wheel 7 is selected from the condition of ensuring the speed and pressure force of the air flow in the injection duct 8 and the vacuum in the ejector sufficient to reliably transport the tow products

(heap) in the tank to collect them. thirty
