Description

The invention relates to agriculture, in particular to decorative gardening, and can be used for the cultivation of plants (e.g. flowers) in a limited area, for example, in an office, on a balcony of an apartment, etc.

The prior art devices for the cultivation of plants in a limited space. In the patent of the Russian Federation 2163755, cl. АСС 31/02, "Device for growing plants without land on a vertical surface", a design for growing plants on a vertical surface is proposed. The device comprises a system for supplying plants with water and nutrients, a means for irrigation, modular elements for installation, care of crops and plant renewal. A feature of the device is the fact that the system for supplying plants with water and nutrients is made in the form of a vertically mounted wall with a vertical arrangement and hollow tubes rigidly interconnected; holes in the hollow tubes are made for attaching modular elements and the flow of water and nutrients to the plants. In addition, the means for irrigation contains a tank for storing water and nutrients, in the upper part of which is located the lower part of the system for supplying plants with water and nutrients, a pump located in a tank for storing water and nutrients, electrically connected to the control unit and connected by means of a hose with a distribution tube located on the top of the system. The device also contains a rectangular frame, and each modular element contains a housing with inlet and outlet tubes and a non-decaying porous substrate placed therein.

The disadvantage of this prototype is the effect of the device on humidity in the room (in particular, overmoistening of the air surrounding the installation), which can be dangerous in an office with an abundance of electrical appliances and electronic equipment. In addition, the apparent simplicity of the design leads to a rather high expenditure of manual labor and the possibility of spills of the nutrient solution, its spraying in case of accidental kinks of the connecting tubes. In addition, the internal space of the installation (a container with a nutrient solution) is not sealed and is not protected from bacterial and fungal infection, which leads to the need for frequent change of nutrient solutions and periodic cleaning of the inner surface of the container after short periods of operation.

The task of the invention is to remedy these shortcomings and create a closed automatic system of plant cultivation with constant sterilization of the internal space of the tank with a nutrient solution.

The tasks are solved as follows

The installation is made in the form of a vertical column (or pipe) of any cross section, which is a supporting structure for many lodgments on which cultivated plants are placed. The lodges are fixed with hooks on the rods and hoops, one of which (lower) is the support, and the second (upper) is made with the possibility of installing the rod with hooks. Almost all hoops located above the lowest perform the function of supporting the lodgement and fixing the rod with hooks at the same time.

Plants with their roots are in the internal volume of the column due to the hole in it at the base of the lodgement. Sealing the hole and preventing light from entering the column is achieved by wrapping the root part of the stem with a porous material (for example, foam rubber) painted black.

The cultivation pipe (column) ends at the top and bottom with funnel-shaped nozzles. One of the nozzles (upper) is made blind (open only from the wide end), but collapsible, allowing installation in a narrow part of an oval and passive (reflective) sprinkler, and in a wide part - a cone mesh filter-distributor for organizing the flow of nutrient solution along the periphery of the cone , that is, almost along the walls of the cultivation pipe, in the zone of the plant root systems. The mesh cone filter is made with a central hole for the passage of the feeding pipe, made coaxially. The feed pipe is made with the possibility of support on the protrusions of both nozzles (upper and lower) to relieve the load from the mesh filter cones.

The other nozzle (lower) is also made with a mesh cone-filter and with supports for the feeding tube, but open at both ends. The narrow end of the funnel-shaped lower nozzle is hermetically inserted into the container with the nutrient solution and serves to drain the nutrient solution into the container.

The feed tube in the lower part is connected to the discharge hose of the motor, made with the possibility of sucking the nutrient solution through another hose with a ball filter.

The container for the nutrient solution is made with the possibility of hermetically fastening the bactericidal lamp or quartz burner in the inner space of the container.

The cultivation column is fixed in an upright position using stretch marks tightening the container and the mounting sleeve on the column into a solid structure. In addition, for additional fixation of the column (for example, decorative garlands or cables), a fixing ring is made on the upper nozzle.

In a brief embodiment, the invention can be characterized as follows:

Installation for hydroponic cultivation of plants, containing a vertical structure for placing plants, a container for a solution, a motor with a pump for feeding a solution to the roots of plants, characterized in that the cultivation column is sealed with upper and lower sealed nozzles and a coaxially located feed pipe, wherein the nutrient solution in the upper nozzle it is sprayed with a passive reflector and distributed on a mesh cone-filter, which allows the solution to flow down the inner wall of the column or Lisi wall in the location area of the root systems of plants, and the plants are arranged in housings in physiological states, stabilizing them throughout the development and nutrient solution is disinfected germicidal lamp inside with a nutrient solution container.

The device is shown in the drawing, which shows the principal components and details of the invention.

The device (drawing) consists of a cultivation column (pipe) 1, ending at the bottom and top with tapering nozzles 2. The upper nozzle is made with a reflective spray 3 and a mesh cone 4 with a central hole for passage of a coaxially located tube 5. The upper nozzle is also made with a mounting ring 6 for stable fixation of the device, for example, with decorative garlands or (in an industrial version) ropes.

The lower nozzle also has a mesh cone 7 with a central hole for the tube supplying the nutrient solution to the upper cut of the cultivation pipe and connected to the hose 8. The motor 9 is also made with a second (suction) hose and with a ball filter 10 at the end.

Both hoses and a ball filter are located inside the tank 11 for the nutrient solution. The container is made with the possibility of tight fixation of the bactericidal lamp 12 (or quartz burner) for sterilization of the nutrient solution.

For physiological fixation of the plant 13 on the cultivation tube, lodgements 14 are made, which rest on the lower hoop 15 and are fixed with hooks 16 to the upper hoop 17, which is the lower supporting hoop for the upstream lodgement.

The cultivation column is made fixed in vertical positions by stretch marks 18, connecting the container for the nutrient solution with the support washer 19.

The device operates as follows

The installation (drawing) assembled and tested for a stable duct of a previously prepared nutrient solution is filled (loaded) with plants 13 in compliance with the necessary tightness. Plants are fixed on the lodgment 14 and turn on the bactericidal lamp 12 and motor 9 in operation. Motor 9 (motor pump) sucks the nutrient solution from the tank 11 through a ball filter 10 and delivers the solution through the injection hose 8 into the feed pipe 5. The solution from the feed pipe on an oval passive sprinkler 3 and distributed over a mesh cone-filter 4 for drainage near the inner walls of the column 1. The flowing nutrient solution irrigates the root systems of plants 13 and through a mesh filter 7 enters the tank 11. Flowing into capacity 11 the solution is disinfected with a bactericidal lamp 12.
