The invention relates to agriculture, in particular to equipment for growing plants in a small greenhouse in the backyard farms, horticultural associations and farms.

When growing plants from seedlings in small greenhouses, especially in the initial period of development of the land plot, where there is no electricity or running water, the problem becomes watering seedlings. For this purpose perforated hoses connected to the water tank, which runs continuously day and night, the actual is to support the reliable periodic watering plants in Teplicka without human intervention and without the use of electricity or wind. The water from the tank to the dosing unit is a siphon, a short tube which is attached to the float inside the tank and the dispenser is made in the form of two adjoining walls of the vessels, having the ability to turn from one stable position to another (when filling one Cup water) around a common axis below the center of gravity of both vessels, and to change the dose of water between touching the vessel wall, above the axis of rotation, a fortified balances, a lot of which can be changed.

The figure schematically shows a device for the metered watering plants without maintenance person and without the use of electricity and the section a-A.

The device consists of a support frame 1, in the upper part of which is fixed a tank 2 for water. In the bottom of the tank onto the protective tube 3. Inside the protective pipe is one of the tubes 4 of the siphon, which is longer than the other pipe 5 at 100-120 mm On the outer surface of the pipe 3 freely wearing the float 6, in which is inserted a short pipe 5 of the siphon so that the end of a length of 10-15 mm is below the bottom surface of the float. At the top of the knee 7 siphon embedded tube 8. In the float cavity 6 provided with a through hole for RA is rubber.

Top tank 2 invoice covered by a cover 11 for water protection from dust and debris. Inside the protective pipe 3, the gap between it and the pipe 4 siphon posted pipe 12, the length of which is selected such that when the lift is fully inserted in the bottom of the tank 2, in the absence of water, the end of the pipe 4 will be 50-60 mm below the bottom of the tank 2. Long siphon tube 4 ends with a change of tube 13 with a calibrated orifice 14.

Below the bottom of the water tank, at a distance of 100-200 mm to the base frame 1, attached volumetric dosing, consisting of a body 15 and a cover 16 having a hole along the axis of the long siphon tube 4. This cover is based in the free state protective tube 12. Inside the housing 15 has two tanks 17, connected by walls and having the ability to rotate around the axis 18, is placed below the center of gravity of the containers. Such location of the axis creates an unstable equilibrium capacities in any position, but being on the stops 19. Between touching the walls of the container, above the axis of rotation, fixed counterweight 20. The body of the dispenser bottom is divided by a partition 21 into two compartments, each of which is in the lower part has a fitting 22.

The fittings 22 are wearing flexible plastic garden hoses 23. In hoses, one obrazcovyj equal to the number of holes in the hose. The end of each hose plugged tube 25 with an air pipe height of 25-30 mm

Installation for metered watering plants is as follows.

Hoses 23 installation placed outside one of the ends of greenhouses for dachas, injected into it, and are arranged in two rows. The clamps 24 are shifted on the hoses so that each clamp is positioned over a hole, and the hole by the rotation of the hose is directed vertically downwards in the groove of the clamp. Each clamp 24 is pressed into the soil of the bed, locking the hose in the desired position. Seedlings are planted at a distance of 3-4 cm from the end of the groove of each of the clip (see the drawing). An air tube 25 is fixed in the ground vertically. Preparation greenhouses for dachas finished.

The original condition of the installation located outside the greenhouse, dry, the water in the tank 2 no. Removing the cover Unscrew the ring 11 of the tube 8. Raising his hand protective pipe 12 muffle tube 13 tube 4 siphon plug (not shown). As the tank 2 is empty, the float 6 lies at the bottom, and the end of the tube 5 of the siphon, resting on the gasket 10 is sealed. This helps seal the dry weight of the float and siphon. Through the opening closed by a stopper 8, the siphon fill in water. Water fill up until it will not start A12, open the outlet 14 of the tube 13 and the tube 12 may be lowered to its original position.

In tank 2 pour a little water. The float 6 bit POPs up and the lower end of the pipe 5 departs from the strip 10. The siphon begins to work, and from the holes of the tube dispenser 14 15 will fill with water, with a flow rate determined by the diameter of the outlet tube 14. The water level in the tank 2 flow is not affected, because the siphon attached to the float, depending on the water level. Ensuring the supply of water to the dispenser (lifting the handset 12), fill tank 2 completely. The tank capacity is selected from the conditions needs to be planted number of seedlings by watering once a day for 6 days.

Water from the bore tube 14 flows into one of the containers 17 of the dispenser. The mass of the counterweight 20 is chosen so that only when set in the capacity of a specific, predetermined amount of water, the system will rotate around the axis 18 (in the drawing clockwise until it stops 19). Under a stream of water from the tank 2 will stand the second tank, and the water from the first will result in a lower part of the dispenser and through the nozzles 22 will fill the hose 23. Since the cross section of the hose is much larger than the total cross section of all the holes in the hose, the water, displacing air">

Formed soamsawali system: the spout 15 and the pipe 25, connected by a hose 23. From the holes of the hose 23, the water begins to flow into the grooves, the locking hose clamp 24, and enters the area of the root system of each plant seedlings.

After some period of time will fill the second tank of the dispenser, and the system will turn counterclockwise until it stops 19 and the water will result in a lower part of the dispenser that is connected to the second hose, there will be watering the second bed.

The alternating metered watering seedbeds will happen automatically, while in the tank is water and the float will not sink to the strip 10 by disabling the trap. The siphon remains filled with water, and for subsequent runs of the system, it is necessary to fill the tank 2 water.

For the implementation of plant nutrition at the same time with their watering in the cavity 9 in the float needs to be put tissue bag with water-soluble fertilizer. The water supplied into the cavity 9 through the through hole, will gradually dissolve the fertilizer, and it is from the tank 2 through the spout 15 gets into the hose, and thence to bed.
