The invention relates to agricultural machinery and can be used in machines for agitating and raking of mowed agricultural crops, as well as in mowing machines.

The purpose of the invention is to intensify the drying of hay by destroying the outer layer of stems with the help of tines and roll-forming devices.

FIG. 1 shows schematically the proposed haymaking machine (option 1), rear view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 3; in fig. 5 - haymaking machine (option 2) e rear view; in fig. 6 - the same, top view; in fig. 7 is a section bb of FIG. 6; in fig. 8 - section GG in FIG. 7; in fig. 9 is a section DD in FIG. 7

The device comprises a frame 1 mounted on a tractor (not shown). On the frame there is at least one rotor section 2, which consists of a bracket 3, an axis 4, a rotor 5, a self-adjusting wheel 6, working bodies 7 mounted on vertical axes 8. The rotor 5 consists of four tubular beams 9-12 form a square and are connected by a central sleeve 13. In the central sleeve 13 there are mounted roller bearings on which the rotor 5 rotates on axis 4. At the corners of the square are installed sleeve 14, in which vertical axes 8 are mounted for rotation. In the lower part of vertical axes 8 s working elements 7 of elastic material. In the upper part of the vertical axes 8 are fixed pulleys 15 connected by a flexible link 16 with a pulley 17 fixedly mounted on the axis 4.

Wind shields 18 (not shown) and upper tines 19, middle tines 20 and lower tines 21, made in the section. -Shaped, for example, from an angle of 25X25, are fixed on the tubular beams 9-12. The rotor section is supported via axis 4 on a self-aligning wheel 6. A pulley 22 is fixed on the rotor 5, which through a flexible connection, such as an endless V-shaped belt 23, transmits rotation from the pulley 24 connected via the PTO shaft 25 to the tractor's shaft. The frame 1 is attached to the frame 1 so that it can be moved along the frame 1, on which the guides 27 are pivotally pivotally rotatable on the sleeve 28 about the axis 29 fixed to the roller former 26 and on the levers 30 mounted in the holes of the brackets 31 on the springs 32 The guide 27 consists of a frame 33 on which the levers 30 are fixed, the corners 34 with guide plates 35 mounted at variable pitch at an angle a equal to, for example, 3-5 °, and made wavy. In the plan (Fig. 2)

guides and trajectories of motion of the tines intersect, and the angle {3 between the tines and the tangent to the inner surface of the guide plates 35 5 on the side of the rotor 5 is less than 90 °.

Haying machine works as follows.

Rotation from the tractor's PTO shaft through the drive shaft 25, pulley 24, V-belt 23 is transmitted to the pulley 22 of the rotor section 2, rotating the rotor 5 on the axis 4. The rotor 5, rotating, moves the working parts 7 of elastic material, which penetrate under the mowed grass and lift her up. Working bodies, turning

15 with the rotor, simultaneously make an additional rotation from the pulley 17 fixedly mounted on the axis 4 and connected by a flexible link 16 to the pulleys 15. Raised mowed grass by the working bodies 7 capture the upper tines 19,

20 the middle tines 20 and the lower tines 21 are transferred in the direction of rotation of the rotor, pressed against the inner surface of the guide plates 35 from the side of the rotor 5 as a result of centrifugal force

25 plants, and also due to the fact that the angle.

In beveled plants that move along the guide plates 35, the outer layer of the stems is destroyed. At the same time, part of the stems with tines 19-21 extends between guide plates 35, and a part moves along the tapering surface of guide plates 35 tapering at an angle. Wind shields provide a better drop of the treated hay from tines 19-21. US35 guiding plates 35 with variable pitch and wave-like provides destruction of the outer layer along the length of the stems. The 21-shaped tines ensure reliable entry of the tines 19-21 between the guide plates 35. When individual lumps of hay hit between the tines 19-21 and the guide plates 35, the guide 27 turns on the hub 28 around the axis 29, which facilitates the exit from the guides plates

45 35 grains 19-21 and lumps of hay. In doing so, the guide 27 is displaced up or down on the brackets 31, overcoming the force of the springs 32. Thus, the outer layer of stems of the cut plants is destroyed and the hay is accelerated.

50 FIG. Figures 5-9 show a haymaking machine with elastic working members, which provide for the cutting of cut grass, with a device for breaking the outer layer of stems. The device comprises a frame 1, hung similarly to the first version of the power tool, which has at least one rotor section 36, consisting of an axis 37, a rotor 38 with working bodies 39, mouth
