Having the ability to install on the cantilever part of two or more cassettes 10, the driven shafts 9 are installed in the diametrical plane of the rotary column 13 (see figures 1, 2, 3, 4, 11). The upper end of the rotary column 13 in the form of a thick-walled steel pipe is welded to the plate 14, and its lower end rests on the flange 15. The flange 15 is mounted on a wide horizontal shelf of the bent profile of the frame 8. The rotary column 13 is mounted on the frame 8 by means of a fixed column 16 ( see figures 3, 4 and 11).

The pivoting column 13 has fixed positions on the frame 8 discretely every 90 ° of rotation angles around the pivoting column 16 due to the holes 17 on the frame 8 and the latch 18. The latch 18 is screwed into the threaded hole on the flange 15 of the pivoting column 13 by the threaded section 19, and the cylindrical part is mounted in the hole 17 of the frame 8 (see figure 3).

The vertical axial displacements of the rotary column 13 in the fixed column 16 are limited by a cylindrical pin 20 mounted in the through holes of the rotary column 13 tangentially to the annular groove 21 on the non-rotary column 16 (see FIGS. 3 and 4).

The cassette 10 (see FIGS. 1 and 2) has a corrugated cross-shaped sleeve 22, two flanges 23, mated with shaped holes 24 with the outer surface of the corrugated sleeve 22. Each corrugated cross-shaped sleeve 22 is placed by means of diametrically oriented pairs of corrugations 25 on the drive shaft 9. The cassette 10 mentioned above, formed by flanges 23 and a cross-shaped corrugated sleeve 22, is fixed by retainers 26 in the form of elastic split rings. The latches 26 are installed in the grooves 27 at the ends of the corrugated sleeves 22 of the cartridge 10 and in the grooves 28 at the ends of the corrugations 25 on the drive shaft 9 (see Fig. 5, 6, 7, 8, 10, 11).

A device for winding into bobbins and layouts of flexible irrigation pipelines of the drip irrigation system works as follows.

Flexible irrigation pipelines 2 of Netafim (the State of Israel), which has been engaged in drip irrigation systems in the world since 1965, supplies the global sales markets, including and to Russia, solid drip lines with wall thicknesses from 0.25 to 1.2 mm in reels 1. The length of the tape (pipe 2) in reel 1 is 600, 1000, 1250, 1500, 1800 and 2300 m. Packed reels 1 to to the consumer are delivered in pallets.

After preparing the field for cultivating, for example, vegetable crops, flexible irrigation pipes 2 are laid out on its surface according to the selected planting (sowing) scheme.

For this (see figure 1) the ends of the pipelines 2 are fixed with brackets on the border of the irrigated array. Frame 8 rods 4, 5 and 6 of the hydraulic system of the mounted tractor 3 are raised above the field surface to a height of 600-800 mm. The tractor PTO 3 is off. Next, the latch 18 is screwed out of the threaded hole on the flange 15 of the rotary column 13. Opposedly installed drive shafts 9 by rotation of the column 13 around the stationary column 16 are installed perpendicular to the longitudinal axis of symmetry of the frame 8.

Then, in each reel 1, a corrugated cross-shaped sleeve 22 of the cartridge 10 is inserted into its hole 10. Flanges 23 are installed on the sides of the reel 1. In this state, the sleeve 22 with the reel 1 is installed sequentially on the corrugations 25 of the driven shaft 9. Then, the latches 26 are installed sequentially in the grooves 27 on the ends of the corrugated sleeve 22 and into the grooves 28 at the ends of the corrugations 25 on the drive shafts 9. Thus, four cassettes 10 are formed on the diametrically oriented drive shafts 9. Due to the kinematic chain in the drive 11, the shafts 9 under tension of flexible tidal pipelines 2 smoothly without jerks in the tensioned position decomposed into field surface. With fully unwound flexible irrigation piping 2, the cassettes 10 are removed from the grooves 27 and 28, the clamps 26 and the operation is repeated (see figure 1).

At the end of the irrigation season, flexible irrigation pipes 2 are wound into reels 1 (see figure 2). Four flanges 23 are sequentially mounted on the drive shafts 9 in series with flanges 23 with cross-shaped sleeves 22 and in the grooves 27 on the sleeves 22 and in the grooves 28 of the corrugations 25 on the drive shafts 9 with clamps 26. The ends of the flexible irrigation pipes 2 are introduced into the slot 29. When reeling up the flexible irrigation pipes pipelines 2, the rotary column 13 with the plate 14 and with the driven shafts 9 is brought from the position shown in figure 1, in the position shown in figure 2.

To exclude dynamic loads on the driven shafts 9 and relieve the load on the latch 18 in the threaded hole of the flange 15, a finger 56 (see Fig. 12) is inserted into the hole in the wall of the frame 8, while the pins 62 are aligned with the slots 63. Then, the handle 59 leads 57 finger 56 is inserted into the hole 58 at the end of the driven shaft 9, compressing the coils 61 of the spring of equal resistance with a shaped washer 60. Then, with the handle 59, the finger 56 is turned 90 ° and released. The pin 62 rests on the vertical wall of the frame 8.

Then, the PTO of the aggregated tractor 3 is turned on when the gearbox is shifted in a neutral gearbox of its chassis. When the telescopic driveshaft shaft 31 of the transmission 11 is rotated, the suspension shaft 32, the intermediate shaft 33 and the receiving shaft 36 of the bevel gear 37 on the frame 8 are rotated. Next, the torque from the gears of the bevel gear 37 is transmitted through the gears to its vertical shaft 39, spline sleeve 38 and the input shaft 40 of the bevel gear 41. Its gears provide a drive for rotating the horizontal shaft 48 with its splined end ends 46 and 47. The latter are connected with sleeves with bushings 49 and 50 at the ends of the driven shafts 9. From the surface of the shafts 9 are torque the moments of force by the corrugations 25 are transmitted to the sleeves 22 of the cartridges 10. When the latter rotate, flexible irrigation pipes 2 are wound into reels 1.

When the cassettes 10 are completely filled, the drive 11 is stopped by turning off the tractor PTO 3. Then, the latches 26 are removed sequentially from the grooves 24 of the sleeves 22 and the grooves 28 of the corrugations 25. The sleeves 22 with the flanges 23 are moved along the corrugations in the direction of the free end of the driven shaft 9. Then the flanges 23 are shifted from the sleeves 22. A twine is introduced into the slot 29 of the flange 29 and the bobbin 1 is tied. Then, the sleeve 22 is removed from the bobbin 1. Then, in two or three places, each bobbin 1 is additionally tied with twine. Ready and strapped bobbins 1 are stacked on a pallet and taken to a warehouse for storage.

The described device design provides the above technical result.
