Description

The utility model relates to the field of agriculture, in particular to the field of horticulture and plant growing using support structures and is intended for fastening steel wire when it is tensioned between the supports of a supporting device for growing hops, grapes, garden trees and fruit bushes

As the experience of advanced countries with developed horticulture shows, the development of intensive plantings using support structures is one of the main directions of agriculture. The same positive trend is observed in the Russian Federation in the most favorable horticultural regions, because Krasnodar region, Rostov, Belgorod, Tambov and a number of other regions. Currently, all gardeners of advanced farms who have begun planting intensive plantings are faced with the question of determining a strategy for selecting optimal support structures that would correspond to the economics of the farm due to their cost and manufacturability in connection with the presence or absence of special technical means and their feasibility in intensive plantings due to their durability.

From the existing level of technology (http://asprus.ru/blog/opornye-konstrukcii-intensivnvx-nasazhdenij-mezhdunarodnaya-praktika-i-rossijskie-realii/) it is known that such support systems are currently used and widespread in intensive gardening structures, such as trellis-type structures, in particular:

- Trellis structures with concrete supports. In the classic version, such structures include concrete pillars (every 25 m along the row line - 140 pcs./ha), 1 wire at a height of 1.8 - 2 m. With drip irrigation, a second wire is often pulled at a height of 20 - 30 cm from the ground surface for hanging watering hoses. Also in structures of this type, an individual support is used for each plant 2.5 m above the ground, fixed to a wire (pine slats 3x3 cm or a treated pine stake with a diameter of at least 5 cm, a bamboo stick with a diameter of at least 3 cm, less often, plastic pipes with a diameter of 2.5 cm or iron reinforcement with a diameter of >12 mm). This system is often used in Hungary, Germany, Holland, Italy, and Poland.

- Trellis structures with wooden support posts. In the classic version, such structures include wooden pine posts placed along a row line at a distance of 15 to 20 meters - 170-230 pcs./ha. This support structure system is often used in developed economies. Widely used in Germany, Holland, Belgium, France, Italy. Partially in Poland, Czechoslovakia, Yugoslavia, Hungary. The main thing in this design is the reliability and durability of wooden poles. Especially during the period of full fruiting.

Moreover, these types of trellis structures can be used both with two trellis wires and with three or more trellis wires (excluding wire for hanging hoses for drip irrigation), such trellis structures are mainly used in super-intensive plantings with a density of more than 3500 plants per hectare and are distributed mainly in countries and regions with developed industrial horticulture, where high planting densities are used.

When installing such trellis structures, much attention is paid to the reliability of fastening the wire in the trellis structure, including its fastening to the support posts and to each other, both in one line and in a perpendicular direction.

There is a known method of attaching a trellis cable to support posts (https://17i7.ru/image/docs/instr_krepl_shpalera_beton.pdf), which involves winding it and fixing it around the support post in a certain sequence, where before fastening the cable, one end of the cable must be wrapped around the post at least twice, then a loop is made around the tensioned cable, and the end of the cable is wrapped in the opposite direction around the pole, after which the end of the cable is inserted inside the loop. After passing the cable through the loop, it is necessary to make a so-called “pigtail”, i.e. braiding around a tensioned cable. The “pigtail” is done in one direction, after which the end of the cable is thrown over the central cable, and the pigtail is made in the opposite direction. Finally, the end of the cable must go back through the loop and it is stored around the circle of the cable wound on the pole.

It is also known that fastening wire to support posts can also be done using staples, hooks and twisting (https://aic-crimea.narod.ru/E-learn/Vinograd/9-2.htm).

A device for fastening trellis wire to support posts is also known from the existing state of the art (SU 1347434 A1; publication date: 1992.06.30; IPC: A01G 17/14; B21F 29/02). The device contains a U-shaped wire clamp with ends bent in a horizontal plane and a device for connecting the clamp to a wire attached to a support post. The device is made in the form of a 6-shaped bracket with parallel sides rigidly attached to the handle. Conical projections having housings with slots are attached to the lower part of the sidewalls. The conical projections are fixed on the sidewalls with the possibility of adjusting their longitudinal position using bolts. At the ends of the sidewalls there are hooks in the form of horizontal slots for trellis wire. With pre-prepared wire clamps, you can widely use the device with trellis wire of various diameters and support posts of various sections, which allows you to expand the technological capabilities of the device

A device for fastening wire to a trellis stand is known, characterized by the fact that the wire is installed in a special groove on a ring put on the stand and fixed in the right place using a toothed wedge (invention patent RU 2403707; Publication date: 08/10/2010; IPC A01G 17 /00;A01G 17/14).

At the same time, the presented known technical solutions for fastening wires in supporting structures for growing plants do not allow fastening the wires to each other. From the existing state of the art it is only known that the wires can be fastened together by twisting, which can lead to damage to the wire used.

The technical result of the proposed technical solution is to expand the arsenal of technical means used to connect wires to each other when installing support structures for growing plants, namely to create a clamp element for connecting the ends of the wire to each other when installing support structures for growing plants, ensuring ease of installation without the use of special tools, eliminating protruding sharp ends of the wires at the joints, ensuring a reliable connection and the possibility of its use in trellis structures of various configurations.

The technical result is achieved in that the connecting clamp for connecting the ends of wires in the supporting structures of supporting devices for growing plants is made of wire spirals connected to each other in strands.

In a preferred embodiment, to increase the reliability of fixation of the wire spirals in the strand, the connection of the wire spirals of the clamp into the strand is carried out using an adhesive connection. In this case, to increase the adhesion of the clamp to the wire, an abrasive material or other coating with a high coefficient of friction can be applied to the inner side of the spiral strand. In this case, wire spirals can also be made of wire with an anti-corrosion coating.

The applicant's analysis of the state of the art, including a search of patent, scientific, technical and other open sources of information, did not reveal any analogues of the claimed clamp for connecting wires to each other when installing support structures for growing plants, characterized by features identical to all the features of the claimed utility model.

The essence of the utility model is illustrated by drawings, where in Fig. Figure 1 shows a general view of a connecting clamp for connecting wires to each other in the support structures of supporting devices for growing plants, made in accordance with this utility model. In fig. 1 it can be seen that in the inventive clamp the ends of the main horizontally oriented wire are fastened, stretched between the supports of the supporting device for growing plants.

The proposed design of a connecting clamp for interconnecting wires in supporting structures of supporting devices for growing plants can be used for fastening and tensioning horizontally oriented wires, trellis wires, trellis cable used in trellis structures and other supporting devices for growing plants. Moreover, the use of the inventive clamp is possible on any section of the main horizontally oriented wire.

As shown in FIG. 1 The spiral strands of the clamp tightly press and secure the ends of the connecting wires used in plant support devices.

The design of the claimed clamp ensures ease of installation without the use of special tools, and eliminates protruding sharp ends of the wire at the points of their connection, which can lead to damage to plants.

Thus, the essential features of the claimed utility model allow us to say that. that the inventive connecting clamp for connecting wires together in the supporting structures of supporting devices for growing plants ensures ease of installation without the use of special tools, eliminates protruding sharp ends of the wire at the connection points and ensures reliable connection of wires to each other in the structures of supporting devices for growing plants.

This confirms the expansion of the arsenal of technical means, namely clamps used to connect wires together when installed in structures for growing plants, the use of which is possible in structures of various configurations, which confirms the achievement of the claimed technical result.
