Description

There is a method of perforation of a mulching roll polymer film, when the film is wound from a roll, pressed tightly to the soil surface and punctured with a metal pin marker (AM Adzhiev et al. “Agroecological fundamentals and technological parameters of grafted viticulture.” Makhachkala: State Unitary Enterprise, Dag. Publishing House - 2003 .-- 296, 209 pp.).

The disadvantage of this method (analogue) is the high complexity of manual labor, the violation of the straightness of planting cuttings along and across the strip, which does not exclude plant thickening in the school, extra passages on the film, which compacts the soil and violates the uniform distribution of moisture after irrigation, especially during normal use of wide 3 meter landing strips. The yield and quality of seedlings is reduced.

A known method of perforation of a mulching roll polymer film, including rewinding the film from a roll to a drum and making holes (SU 1777709, class A01G 13/02, BI No. 44, 1992, p. 8.) - prototype.

The known method has the disadvantages of:

- In rolls, the ends of the film, as a rule, are not aligned, and after the holes are made with radial knives, the straightness of the lines is violated, respectively, the soil from the zagrezachchi either does not sprinkle the edges of the film, or fill the holes in the extreme row, which will impair the quality of irrigation and affect the yield and quality seedlings.

- Knives make elongated holes in the film in the form of longitudinal slits through which moisture evaporation and weed growth increase, which also reduces the yield and quality of seedlings.

The aim of the present invention is to ensure the accuracy of the planting scheme of cuttings, increasing the yield and quality of seedlings.

This goal is achieved by the fact that in the method of perforation of a mulching roll polymer film, including rewinding the film from a roll to a drum and making holes, the film from a roll is rewound onto a perforated drum, while combining its ends, simultaneously with rewinding, cut the stocking of the film on one side, perforation the films are drilled by holes in the film according to the pattern and rewind again into the same roll. In this case, rewinding can be carried out on a roll of an already deployed stocking of a perforated film. The method allows in advance (for example, in the winter period) to prepare the required amount of perforated film in the form of conventional rolls or in the form of rolls of an unfolded film stocking.

Pre-perforation of the film roll after rewinding to a larger diameter is an essential technique, since perforation of the film roll without rewinding to a larger diameter violates the step of planting cuttings, which decreases as the unwinding of the roll decreases.

The rolls of polymer film supplied to the distribution network, as a rule, have shifted ends, therefore, the reception when the ends of the film are combined during rewinding is essential, since the "swimming" of the landing stitch in the strip in the transverse direction is eliminated. Cutting on one side of the film stocking at the time of unwinding the roll before covering the landing strip is a laborious and extremely inconvenient manual process. Therefore, combining this operation with rewinding a roll is also an essential technique.

New in this invention is the combination of all these operations to prepare the mulching film with more accurate perforation, saving labor costs and working time (it takes only 15 minutes to perforate one 100-meter roll).

The essence of the invention will be clear from the drawing of the device for perforation of a mulching roll polymer film made in accordance with the proposed method of perforation.

A device for perforating a rolled polymer film consists of a bed 1, on which, through bearings 2, the axis 3 of the rewinding drum 4 with handles 5 is mounted. The surface of the drum 4 is perforated with holes 6 according to the pattern of planting cuttings. Holes 7 are also made along the edges of the drum 4 with the same step as the holes 6, for mounting the fingers 8 of the template 9 with the holes corresponding to the holes 6. At the ends of the template 9 and on the bearings 2 there are hooks 10 for fastening the elastic bands 11, which provide pressing the template 9 to the surface of the drum 4. On the axis 3, with the help of hooks 12, the axis 13 is freely suspended on which a roll of polymer film 15 is fixed using bushings with conical feathers 14. To fix the roll 15, holes are provided on the axis 13, where cotter pins (not shown) are inserted, which prevent the rotation of the roll 15 relative to the axis 13. The axis 13 has handles 16. A special knife 17 is fixed on the frame 1 with two bolts (not shown), on one of which the knife 17 rotates freely when another bolt is released.

A device made by the specified method works as follows. The template 9 is removed from the drum 4, then the axis 13 is passed through the tube of the roll 15 (usually made of plastic) and, using the sleeves 14 and cotter pins, the roll 15 is secured against turning on the axis 13. Put one of the removed arms 16 in place and suspend the axis 13 s roll 15 onto hooks 12 so that, for example, the left (according to the drawing) end face of roll 15 is opposite the mark on drum 4. The distance from the mark to the first hole 6 is half the line spacing, then after perforation and opening of the film stocking, line spacing is maintained. Lay a knife 17 between the films and press it with a bolt to the bed 1. The end of the film is thrown onto the drum 4 and fastened with adhesive tape in two, three places. The rewinding process can be carried out by one person, for which they rotate the handle 5, and with the other hand, shaking the roll 15 freely suspended on hooks 12 along the axis 13, monitor the installation of the end of the film, combining it with the mark on the rotated drum 4. After rewinding, set the template 9, is thrown onto the hooks 10 of the elastic band 11, which presses the template 9 onto the film rewound on the drum 4. Drills holes are drilled through the template 9, rearranging it in a circle and fixing in the holes 7. When the drum 4 rotates, the knife 17 cuts the right (according to the drawing) side of the film stocking.

Rewind the film to the tube of the same roll 15 by rotating the right or left handle 16. Remove the roll 15 from the axis 13 in the reverse order. Rewinding can be carried out on a bar longer than the width of the landing strip, which is placed on special goats installed at a distance from the bed 1, and, rotating it, rewinds the film, while two workers unfold the stocking of the film.

The proposed method of perforation of a mulching roll polymer film can significantly reduce the complexity of the perforation process and time, as well as improve the quality and yield of seedlings.
