Description

The utility model relates to the field of growing plants, namely to autonomous devices that condense moisture from atmospheric air and bring it to the root system of plant seedlings, and can be used in agriculture, household and forestry for growing various crops and trees.

A device for irrigating a plant is known, which consists of a toroid-shaped body, truncated in the lower part, having a hole in the center and made of a transparent material, an absorption layer of a highly absorbent material and a condensation layer of a highly porous material with high thermal conductivity are attached to the body by means of clamps. , there is a hole in the central part of the condensation layer and the absorption layer, there are ventilation holes in the lower part of the body (see utility model patent RU156073.MPK A01G25/00, publ. 27.10.2015).

However, it cannot be used on a grown plant and does not provide the necessary amount of moisture during temperature changes.

A device is known for collecting and supplying moisture to plant roots (see utility model patent RU79747, IPC A01C14/00, publ. triangular section along the outer edge of a smaller diameter and a vertical cut along the entire height of the funnel. The collection of moisture by this device is carried out due to its condensation on the walls of the funnel. The process takes place with the participation of sunlight, which freely penetrate the transparent wall of the funnel and evaporate moisture from the soil layer. The moisture evaporated from the soil comes into contact with the walls of the funnel, which are colder relative to the soil, and condenses into drops, which then flow down the outer surface of the funnel to the roots of the plant.

The disadvantage of this device is its low performance in terms of the amount of condensed moisture due to the lack of free access to moist atmospheric air under the funnel, as well as due to the low thermal conductivity of the plastic funnel body, which is not able to intensively remove heat into the atmosphere during moisture condensation.

A device for irrigating plants is known, containing a water-collecting sheet for collecting moisture present in the atmosphere, equipped with a water-collecting surface containing a receiving surface that functionally forms a first angle relative to the orientation of gravity, and a collecting surface adjacent to the lower edge of the receiving surface, and this collecting surface is functionally forms a second angle relative to the direction of gravity, and the first angle is less than the second angle. A central hole is made on the lower edge of the collecting surface, while the collecting surface has a slope and contains radially passing sections of channels for directing moisture drops into the lower part of the sheet for collecting water to deliver moisture in the immediate vicinity of the place where plants are grown from the central hole, and in which the surface for collecting water contains radial protruding ribs (see patent US752330, IPC A01G13 / 00, publ. 06/17/2014).

However, this device is quite complex. In addition, water is directed to an auxiliary reservoir, and not directly to the root.

The closest in essence to the proposed utility model is a device for collecting moisture present in the atmosphere (see patent NL 1029216, IPC A01G13 / 02, E03B3 / 28, publ. 12/11/2006), which is a container with a pipe located in the central part, in which the irrigated plant is located. A ribbed surface inclined towards the center is installed on the container body to collect moisture, which has a heat-insulating material on the underside. In the bottom of the container body there is a hole with a stopper made of porous material to control the amount of moisture supplied to the roots of the plant.

The disadvantage of this device is its low productivity in terms of the amount of moisture supplied to the roots of the plant.

The technical problem is to create a simple ecological element of the irrigation system.

The technical result consists in increasing the efficiency of cultivation by protecting plants from sudden temperature changes while increasing the interval between watering the plant.

The technical result is achieved by the fact that in a device for irrigating plants, containing a housing with a surface for collecting moisture from atmospheric air and a hole in the center, according to the solution, the housing has a cone-shaped bottom and a cylindrical side surface, the bottom of the housing is divided by stiffening ribs into V-shaped grooved sectors, tapering to the hole, while the body has a V-shaped cutout limited by the walls for inserting the device under the plant.

The walls of the stiffening ribs are corrugated and have a wedge-shaped shape, tapering towards the hole. The case is made of polypropylene with a diameter of 170 mm and a height of the cylindrical side surface of 15 mm, the height of the stiffening ribs is 5 mm, the hole in the center has a diameter of 30 mm, the bottom is made with an inclination to the hole of 20 degrees, and the number of V-shaped sectors is 15 pieces.

The device is illustrated by drawings, which show:

in fig. 4 - plot of temperature versus time in partial shade;

The device contains a body 1 made of opaque (dark) polypropylene. The body 1 has a cone-shaped bottom 2 with a hole 3 in the center and a cylindrical side surface 4. The bottom of the body 2 is divided by stiffening ribs 5 into V-shaped grooved sectors 6. The stiffening ribs 5 are made corrugated. The housing 1 has a V-shaped cutout 7 limited by walls for inserting the device under the plant.

The device covers the plant's root system, directing water and fertilizer directly to the root, protecting the ground around the root from weeds and extreme temperatures. In rainy weather, the efficiency of water absorption increases. It also blocks the sun's rays, preventing the development of weeds. It is most expedient to manufacture the device in the form of round corrugated low monolithic "trays" from recyclable plastic by stamping.

The plant is placed in hole 3 through cutout 7 and pressed firmly against the ground for better air isolation. Night temperature difference leads to the appearance of condensate on both surfaces of the platform, which, with the help of sectors 6, is directed directly to the roots.

After testing on an open land plot, in partial shade and shade, a pattern was revealed, namely: the device takes on excess sunlight and heat, thereby protecting the plant from sudden temperature changes and rapid drying of the soil. The confirmation of device operability is supported by the research results, which are presented in Fig. 3-5.

By comparing the average temperatures (Fig. 6), it is clearly shown that the change in the temperature of the soil surface without the device during the day takes on new temperatures much more often (both higher and lower), which differs from the change in temperature under the device, where the temperature takes on more measured new values. In other words, it performs a thermal insulation function, and also reduces the sharpness of temperature changes, which makes it possible for the plant to have time to prepare for a cold snap or extreme heat.

The device allows you to reduce the consumption of fresh water, provides protection from wild plants. They block sunlight, which protects the plant from drying out near-surface roots and prevents the germination of wild plants. Using recycled plastic reduces waste. Moisture under the device is retained for a longer time. The design of the device contributes to the flow of condensate under the device and provides natural irrigation of the earth in the absence of penetrating light.
