Description

The utility model relates to agriculture, in particular to the production of vegetables in greenhouses with hydroponic installations.

The use of hydroponics in growing various crops is a promising solution.

A standard design of a hydroponic plant is known, which consists of the main units: a frame, a bath for a nutrient solution, a pump, additional tanks with a solution, a canvas for planting plants, a frame for installing lighting (See patent RU 110917 U1 "Hydroponic plant").

The disadvantages of the standard design are the need to install a container for the solution over the entire planting area, lighting is also necessary throughout the structure, the wetting of the roots is carried out by feeding the solution with a pump into the bath on a timer, the need for additional tanks for the solution, to create a microclimate requires a volumetric structure.

There is also rotary hydroponics. The design is based on a rotor revolving around a light source, the planting area for seedlings is located on its inner cylindrical surface (See the link "Analysis of existing structures" [Electronic resource], Access mode: https://overgrower.ru/shelfs).

The device for rotating microgreens is a cylindrical shape (rotor) intended for the installation of cultivated plants.

In the patent No. 2013935 "Hydroponic plant" there is a design. A distinctive feature is the use of a rigid frame with the use of trays on telescopic beams for planting.

There is also hydroponic systems, in the design of which rotation is provided by an electric motor using a belt drive (See AI Noskov "Technical systems in hydroponics" 2020. 17-21 p.). Similar designs have the following disadvantages: the use of additional elements (pumps for supplying solution to the bath, additional baths, various belt tensioners), large overall dimensions of the structures.

The task of the utility model is to develop a device for growing microgreens using the hydroponic method.

The problem is solved by the fact that a device for growing microgreens by the hydroponic method, including a cylindrical rotating element designed for installing plants in it, and also a rotating element is made in the form of a rotor with holes and used as a frame for installing plants in square pots in these holes , and the roots of the plants are directed from the center of the rotor to the periphery, in addition, the rotor is mounted on four toothed rollers located in pairs on two axes and above the bath with a nutrient solution, and its drive is carried out due to the operation of an electric motor using a toothed belt fixed along the entire outer diameter rotor and interacting with toothed rollers, and in the center of the rotor there is a lamp for illuminating the plants, the belt is fixed along the entire diameter using cyanoacrylate and similar adhesives, when installing plants, square holes are used for square pots, for installing microgreens eight square holes.

FIG. 1. shows the main parts of the proposed design: cylindrical surface 1, 2 holes for planting, made in the form of a square, 3 flanges, 4 toothed belt.

FIG. 2 shows a general view of a device for growing microgreens by the hydroponic method: 5 a device with holes for planting plants, 6 a bath for solution, 7 four toothed rollers for installation, located in pairs on two axes, 8 an electric motor, 9 a lamp.

The device 5 is installed on toothed rollers 7 above the bath 6 with a solution. The electric motor 8 drives in rotation a pair of rollers 7 located on the same axis, which, by means of gearing, drive the device 5.

Plants are fixed in the square holes of the device 5, with roots on the periphery. When rotating, the roots of plants are moistened with a solution in a bath 6, getting all the useful substances. Lamp 9 is installed in the center to illuminate the plants.

This design will allow you to grow a larger number of different plants, occupying a smaller area, due to the use of a cylindrical device. Plants will be installed in special square holes. Also in this structure, a bath with a solution is used, installed under the entire structure. When rotating, the roots of the plants fall into the bath with the solution, thereby providing the roots with the necessary looping substances.

Various crops can be grown using this hydroponic device: dill, parsley, etc.

Rotary hydroponics allows you to plant a variety of crops in a small area. For example, let's take the inner diameter d = 0.6 a . For the same length b, the rotor cultivation area S _mouth will be

...

The area ratio in this case will be almost a 2-fold advantage over the standard hydroponics design, which is not the limit. The combination of certain design features may exceed this indicator (See L.A. Paltsev, A.I. Noskov "Resource-saving technologies for growing plants using rotary hydroponics" 2019. 234-236 p.).

The device can be made of various materials: plastic, steel (See Sadov A.A., Shorokhov P.N., Yusupov M.L., Zelenin A.N. "Requirements for rotary hydroponics" 2019. 105 p. ).

The design development costs are significantly lower in comparison with various similar designs due to the absence of additional elements (pumps, belt tensioners connecting the cylindrical shape and the electric motor, additional tanks), the use of a cylindrical device reduces the overall dimensions of the entire structure.

This design has the following advantages:

1. According to the calculated data, the use of the rotor allows one to reduce the overall dimensions of structures without reducing the number of grown plants.

2. Due to the rotation of the rotor, the plants are not constantly in the solution, which makes it possible to exclude additional units (pump, container).

3. Complexity is simplified by using a fixed toothed belt over the entire rotor diameter, excluding additional belt tensioners connecting the cylindrical shape and the electric motor.

4. This design of the device will significantly reduce the cost of manufacturing and maintenance of all hydroponics, due to the lack of additional parts.

When developing a device for growing microgreens using the hydroponic method, all the disadvantages of similar types of structures were taken into account. This useful model will significantly simplify and facilitate the design of rotary hydroponics due to the use of a fixed toothed belt along the entire rotor diameter, excluding the use of various additional parts. The use of this design will reduce the cost of manufacturing a plant for rotary hydroponics and reduce the overall dimensions of the entire plant.
