FIELD OF THE INVENTION The invention relates to agricultural machinery, can be used in machines for harvesting flax and is an improvement of the device according to cars, no. 1271428

The aim of the invention is to increase the reliability of the process and the quality of the spread out ribbons with different lengths of stems,

Fig. 1 shows a device for wrapping and spreading flax ribbons in a side view; Fig 2 is the same, top view; Fig, 3 - device section; FIG. 4 shows the output rings of the withdrawing belt-finger conveyor and the pressing drum, side view; FIG. 5 is a section A-A in FIG. 4,

The device for wrapping and spreading flax ribbons comprises a frame 1 on which a pick-up drum 2 with fingers 3 is mounted and a feeding conveyor, for example, of clamping type, formed by surfaces of endless top 4 and bottom 5 belts in contact with working bodies. The upper endless belt 4 around the drive and driven pulleys 6 and 7 and the deflecting roller 8, the lower end of the infinitely fingering 31 through the spiral channel turns on 180 and goes to the 39 of the pressing drum, rolling along the soil surface and copying its microrelief, B At the place where the stems descend from the lower end of the outfeed conveyor, the stems are removed from the fingers 31 of the endless belt by 30 separate sections 39 of the pressing drum and rolled by them to the soil surface. When wrapping and spreading dopinfree flax ribbons, the eccentrics 37 turn around the axis of the driven pulley 32, increasing its height above the soil surface and thus ensuring the optimum height of the vanishing point of the fingers 31 of the belt-belt conveyor and the angle of removal of the stems by sections 39 of the pressing drum, 5 silt

The belt 5 bends around the drive pulley 9, the pickup drum 2 and the deflecting rollers 10. Axle 11 of the support-copy wheels is rigidly connected to the frame 1.

The frame 23 is connected to the shaft 19 through the ball bearing 25, the lead shiv 24 is mounted on the shaft 19 on the key 2ft. For fixations from the axial displacement of the driving pulleys 9 and 24 and the bearings 25 on the shaft 19 there are spacers 27 and 28, Shaft 19 is driven for all mechanisms of the wrapping and spreading device

The axis is fixed in brackets 35 so that they can be rotated and fixed against axial displacement by spacer sleeves 36. On both sides of the driven pulley 32, eccentrics 37 are rigidly fixed on its axis 33. On eccentrics 37 on ball bearings 38 mounted sections 39 of the packing drum. Sections 39 are secured against axial displacement by spacer sleeves 40 and secured to eccentrics 37 by means of a locking bolt 4I.

On the frame 23, in the place of attachment of the brackets 35, there is a bracket 42, and on the eccentrics 37 there are sectors 43 with a number of holes. The position of the eccentric 37 with respect to the axis of the pulley 32 is fixed, for example, by a pin 44 entering the holes of the bracket 42 and sector 43,

The guide rods 45 are mounted on frame 23, Hydraulic cylinder 46, which serves as a dp for converting the withdrawing belt-and-finger conveyor to the transport position, is pivotally connected to frames 1 and 23, with which the spring 47 is pivotally connected, weight output belt belt-pin conveyor.

A device for wrapping a flax spreading sheet works the following way.

Before the machine starts to move across the field, all mechanisms of the wrapping device and spreading the flax ribbons are put into operation, the shaft 19 is rotated through the cardan gear (not shown). When the device moves across the field in the direction indicated in FIG. 1 by the arrow, the pick-up drum 2 with fingers 3 lifts the flax ribbon and moves it to the clamp with endless belts 4 and 5, which are fed to the output belt-pin conveyor. In the process of transporting the ribbon by an endless cross-strap 30 with fingers 31 along a helical channel bounded by guides 1, ruts 43, the ribbon of flax stems unfolds 180 and post

plowed to sections 39 of the pressing drum, rolling on the surface of the soil and copying its microrelief.

In the place where the stems descend from the lower branch of the outgoing transporter, the stems are removed from the fingers 31 of the endless belt by 30 individual sections 39 of the applicator drum and rolled onto the soil surface.

When wrapping and spreading the ribbons, the eccentrics 37 turn around the axis of the driven pulleys 32, increasing its height above the soil surface and. thus, providing the optimum height of the point of descent of the stems from the fingers 31 of the belt-pin conveyor and the angle of removal of the stems by the sections 39 of the press drum.

When using the device for spreading flax tapes only, instead of the cross-belt 30, a conventional non-cross-belt is installed, i.e. in this case, a conventional belt drive is used. The eccentric is turned 37 times around the axis of the driven pulley 32, reducing the height of the vanishing point of the stems from the fingers of the belt-pin conveyor from the soil surface.

The raising and lowering of the withdrawing finger-belt conveyor is performed by a hydraulic cylinder 46. In the working position of the withdrawing finger-belt conveyor, the hydraulic cylinder 46 is in a floating position, allowing the press drum sections 39 to replicate the unevenness of the soil.

The spring 47 establishes the force of pressure from the mass of the pull-in belt-and-finger conveyor, which comes from section 39, Mening the stiffness of the spring 47, and the pressure of section 39 on the soil surface can be varied (or the strip of attached stems).

The proposed design of the device increases the reliability of the technological process and the quality of distributed tapes.
