Description

The utility model relates to auxiliary technological equipment for use in greenhouses of general and industrial importance and is intended for gartering plants.

To obtain a high yield, it is necessary to tie up plants (tomatoes, cucumbers, etc.), avoiding the bending (fracture) of the stem. Hooks for garter, for example, tomatoes in a greenhouse, help fix the plant with an increase in the mass of the fetus and prevent bending. Hooks also help keep plants above the ground and prevent damage to the fruit by pests. Garter makes watering and irrigation easier. A properly located plant receives more nutrients and is able to produce high yields. As it grows, it is necessary to lower the garter with the plant to prevent damage.

Known unwinding hook for a rope designed to guide the growth of climbing plants (Patent RU2620000C2), which includes at least one hook designed for hanging on a support cable (trellis), and at least one unwinding coil designed to receive the rope from reel, characterized in that the hook is made of flexible wire and has a first trough, which includes a cable (trellis), and the unwinding reel is equipped with a second trough, in which a coil of rope is wound on the first trough, first chute is substantially perpendicular to the second chute for ejecting the cable when attaching it to hook a coil of rope is unwound from the reel.

When working with the above hook, there is a high probability of damage to the tied plant during the lowering process.

As a prototype, a coil of a mobile adjustable system for plant garter (Patent FR2743258A1) was selected using a wire bracket - a coil holder, the upper part of which is equipped with a hook for hanging it from a carrier cable (trellis). The plastic coil is mounted to rotate around the transverse axis in the lower part of this holder (wire bracket), while one of the side walls (flange) of the coil contains a radial protrusion, and this holder (wire bracket) contains a spring-loaded locking lever having a transversely oriented part, located on the circular path of the radial protrusion. The combination of a plastic spool and a wire bracket is a reasonable compromise between strength and weight of the structure.

Due to the constant contact of the radial protrusion and the springy locking lever, the radial protrusion stitches or breaks off, which leads to the fall of the plant from the trellis and its death.

The technical problem to which the utility model is aimed was to increase the reliability of the coil for lowering greenhouse plants.

The technical result is the exclusion of the fall and death of the plant due to the improvement of the locking mechanism.

This technical problem is solved by a coil for lowering greenhouse plants for installation on a wire bracket suspended on a trellis made of plastic and having a radial protrusion on one of its side walls to stop rotation relative to the wire bracket due to contact with the spring-loaded fixing lever of this bracket, in which according to the proposal, an additional protrusion is made on the side wall to stop rotation.

The strength of the coil, and, consequently, the achievement of the specified technical result, is obviously affected by the design of the winding rod (axis of the coil). In the prototype, the winding rod has a cross-shaped cross section. In the proposed coil, the winding rod is made in the form of a part with a Z-shaped cross section and transverse stiffening ribs. This embodiment provides the necessary strength, uniformity of winding. In addition, it becomes possible to increase the width of the coil without increasing the diameter, which, ceteris paribus, allows for winding a longer length of twine on the coil and ultimately increase the life of the coil.

It is also advisable to make the coil of light-stabilized plastic, that is, a plastic having high resistance to UV radiation.

The utility model is illustrated by drawings.

In FIG. 1 shows a general view of a coil for lowering greenhouse plants.

In FIG. 2 shows a cross section through a coil.

The coil for lowering greenhouse plants consists of a winding rod 1 and side walls (circles) 2. To install the coil on a wire bracket (not shown), its design has protruding axial sections 3 with a landing neck. On the side wall of the coil there are two radial protrusions 4.

The coil for lowering greenhouse plants is used as follows.

The coil with the twine wound on the winding rod 1 is suspended above the plant. To unwind the twine, the protrusions 4 are pulled out of the hook with a spring-loaded locking lever (not shown) - the coil rotates freely. The unwinding field of the required length of twine and fixing it to the plant, the coil is stopped by one of the radial protrusions 4. In the process of plant growth, it becomes necessary to lower it, that is, to unwind an additional section of twine. This is easily accomplished by disengaging the protrusion 4 for free rotation of the coil and unwinding of the twine. The protrusions 4 are either used alternately, which increases their resource, or after the breakdown of one protrusion 4, another is used.

The design features of the coil, including the increased width, allow winding up to 32 meters of twine, and operate the coil for up to three years.
