The invention relates to agriculture, namely the cultivation of plants in greenhouses.

A device for automatic control of irrigation greenhouse containing a water tank, a rocker pivoted on the axis of the vessel, attached to the ends of the rocker arm and the distribution pipeline [1]

The disadvantage of this device is the possibility of the return movement of the rocker before emptying the vessel. In addition, due to the strict regulation of the number of irrigations per day regardless of the temperature and humidity decrease Y essence and the achieved result when using a device for automatic control of irrigation greenhouse, contains a water tank, a rocker arm mounted on an axis, moving the cargo placed on both the shoulders of the rocker arm, the blood vessels attached to the ends of the rocker arm, and the distribution pipeline [2]

The disadvantage of this device is the hard rhythm of irrigation (watering time), regardless of the soil moisture in the greenhouse. This can lead to waterlogging of soils in cold days and drying on hot, that not all plants are acceptable. Additionally, when working with large greenhouse space vessels capacity must be large, which increases the overall dimensions of the device. The device does not provide a continuous measurement and maintenance of set values of moisture in the soil regardless of humidity outside of a greenhouse. This reduces the technological capabilities of the device.

The objective of the invention is the expansion of technological capabilities greenhouses, namely maintaining optimal for growing plants soil moisture in the greenhouse, regardless of ambient humidity.

For this purpose, the axis is made in the form of a valve body of the valve and rigidly connected to the rocker arm, the movement of which is limited by the magnetic stops mounted for movement along nahodites. In addition, the height of the vessel, the evaporator is not less than the depth of the germination of the root system of cultivated plants, and the area is not less than sufficient space for growing one plant, while the vessel evaporator is made with a perforated surface. Furthermore, the magnetic stops made in the form established in the buildings of permanent magnets and damping elements. In addition, the damping elements made in the form of spring-loaded plungers mounted in housings magnetic stops can be moved in the perpendicular relative to the located near the beam direction.

Comparative analysis of the essential features of the prototype and the proposed technical solution confirms that some essential features of the claimed together are identical to the characteristics of the prototype, namely, a water tank mounted on the axis of the arm, both arms of which is placed a sliding cargo vessels associated with the ends of the beam, and the distribution pipeline. Others are new, i.e., the axis is made in the form of a valve body of the valve and rigidly connected to the rocker arm, the movement of which is limited by the magnetic stops, ostanovlu the form of a vessel of the evaporator. In addition, the height of the vessel, the evaporator is not less than the depth of the germination of the root system of cultivated plants, and the area is not less than sufficient space for growing one plant, while the vessel evaporator is made with a perforated surface. Furthermore, the magnetic stops made in the form established in the buildings of permanent magnets and defirous elements.

In addition, the damping elements are magnetic stops made in the form of spring-loaded plungers mounted in housings magnetic stops can be moved in the perpendicular relative to the located near the beam direction. From this, the Complainant concludes that the claimed technical solution has an eligibility criterion of "Novelty."

The comparison of the proposed solutions not only prototype, but also with other technical solutions related to this technical field, not revealed in the latest signs that distinguish the claimed solution to the prototype. The inclusion of the new device features and their relationship gives him a new property that allows to expand possibilities for technology to constantly measure and provide the specified soil moisture in Sa new property show a new set of essential features that provide a new technical result that, according to the applicant, confirming the presence of the declared object of the eligibility criterion of "Inventive step".

The drawing shows the proposed device.

The device comprises a container 1 for water and located beneath the rocker 2, mounted on the axis 3. Axis 3 is made in the form of a valve body of the valve 4, for example, plug valve, which is connected with a hose 5 with capacity 1 and also connected to a distribution pipe 6.

One end of the rocker arm 2 by means of thrust 7 is connected with a vessel-counterweight 8, and the other through the rod 9 is connected to the vessel by the evaporator 10, the thin surface which is made from perforated. The height of the vessel is not less than the depth of the germination of the root system of plants 11, and its area is not less than sufficient space for growing one plant.

Moving the rocker arm 2 about the axis 3 is limited to magnetic stops made in the form embedded in the body 12 of the permanent magnets 13 and damping elements, including a spring-loaded t is m relatively near their arm 2 direction. The housing 12 are able to move along near their arm 2, on both shoulders which is placed a sliding cargo 16, at a position which is limited by stops 17.

The pushers 15 provide a smoother (unstressed) approach rocker 2 magnets 13, as well as create additional time with the disengagement of the arm from the magnets, which contributes to a more secure passage of the rocker part of the way to the horizontal position, after which come into effect sliding cargo 16. Thus the force of the spring 14 should be slightly more than the force of gravity pushers 15 magnets 13. The vessel is opposed to 8 may be performed, for example, in the form of a pipe with a plug at the bottom, which is filled with a hygroscopic filler preset weight and is used to trim the vessel of the evaporator 10, the soil 18 in which the humidified to the desired degree and must be harder when the soil dries to the desired value, when it is necessary to include irrigation.

Vessel-evaporator 10 is filled with soil 18, similar in the greenhouse, after which it is planted not less than one plant 11 plant in the greenhouse. Vessel-evaporator 10 is under the distribution pipe 6, the tel 10.

When setting device provided with the same conditions of moisture for the soil, in the vessel of the evaporator 10 and the soil in the irrigated area (in particular the selection of the number of punched holes in the vessel-evaporator simulating drainage capacity existing between adjacent parts of the soil and its depth in the recess 19 of the soil), supply the same amount of water per unit volume of soil. Movement of the housings 12 with magnets 13 are set thresholds beginning of rotation of the rocker arm 2.

The device operates as follows.

The soil in the greenhouse and the vessel of the evaporator 10 are the minimum humidity value. The soil in the greenhouse and the vessel of the evaporator 10 are the minimum humidity value. Vessel-evaporator 10 is in its upper position, the Cam 2 in position I, in which a stop valve 3 valve 4 opens the valve 4.

The tank 1 is filled with water through the hose 5 through the valve 4 flows into the distribution pipeline 6. Is the irrigation of the soil in the greenhouse and in the vessel of the evaporator 10. With increasing humidity of the earth in a vessel of the evaporator 10 mass also increases, but the lever 2 under the action being around him magnet 13 remains in polozhenie 2 is detached from the magnet 13 and is rotated with the axis 3 in position II. The valve 4 is closed, stopping the flow of water in the pipe 6. With the disengagement of the rocker arm 2 from the magnet 13 under the action of the spring 14, the pusher 15 is also detached from it, letting the rocker 2 additional moment. When the same approach to the opposite extreme position of the first rocker interacts with the plunger 15 and, overcoming the resistance of its spring 14, reaches the magnet 13. The plunger in this position attracted by a magnet, partially offset pulling effect on the rocker arm 2 spring 14.

As drying and moisture absorbed by its roots (as in the soil of the greenhouse and into the vessel 10) weight of the vessel-evaporator 10 begins to decrease. When the difference in the masses of vessels-evaporators 8 and 10 with the force of attraction by the magnet 13 of the rocker arm 2 reaches the preset value (soil dries to the maximum allowable value), the rocker 2 is detached from the magnet 13 and is rotated together with the axle 3 in the other extreme position I. the Valve 4 opens and the cycle repeats.

Thus, the device provides a continuous measurement of the amount of moisture in the soil and control with shut-off body of the faucet water supply distribution piping, which is the irrigation of the soil. Otkrysya plant values. The device allows automatic watering for a long time (capacity 1 may be communicated with the water supply system and has a valve float type), as small greenhouses and large greenhouses.

With the help of the device can be maintained at optimum soil moisture for each type of crop, regardless of the ambient humidity. As plant growth, and if necessary, changes to irrigation regimes, depending on the terms of their vegetation may be adjusted thresholds triggering device by moving blocks with magnets in one direction or another, and changes to vessel weight counterbalance.

Comparative analysis shows that the proposed device in comparison with a device for automatic control of irrigation greenhouse adopted for the prototype, provides a broader technological capabilities, allows you to maintain soil moisture in the greenhouse within the specified limits, regardless of weather conditions and soil moisture outside of a greenhouse. The proposed device is compared with the prototype has a broader technological capabilities.
