The practical operability of the proposed installation is obvious and it fits compactly into the metering tank for growing plants in closed ground.

So, the analysis of the revealed information about the current level of technology in this field and the essence of the invention showed that the latter meets the patentability criterion of "novelty."

Thus, the claimed combination of essential features of the invention is a technical result in all cases to which the claimed legal protection applies.

In the course of the analysis by the applicant of the search for information in the field of agriculture, certain distinctive features of the claimed invention were discovered among well-known objects of the same purpose. However, the set of essential features of the invention, contributing to the achievement of a new technical result, and its effect on the subsequent from the existing level of technology, is not found.

It is the combination of essential features that allows you to get a new technical result - simplifying the design of the installation by making the adjusting device compact, efficient, reliable in operation.

Therefore, the present invention has such a patentability criterion as "inventive step".

The invention is illustrated in the drawing.

In FIG. 1 shows a diagram of a General view of the installation; in FIG. 2 - an embodiment of a two-shouldered lever swinging on an axis with a tension spring is presented.

The automatic irrigation installation includes a metering tank 1 for accumulating water with a water outlet 2 of the outlet pipe 3 and a drain hole 4, the free ends of which through the pipelines are connected by a water distribution system 5 in greenhouses or beds, etc.

At the same time, the adjustment device is made in the form of one nozzle 3 compactly mounted on the clamp 6 on the housing, on which the clamp 6 is placed. The bracket 7 is fixedly fixed to the clamp 6 with the two-arm lever 8, which rotates on the axis 9 in the middle part of the arm 7. The two-arm lever 8 is made L-shaped.

The upper end of the lever 8 is provided with a counterweight 10 with the possibility of changing its moment of weight. The lower end of the lever 8 is equipped with a locking member in the form of a plug 11, made in the form of a hemisphere of dense, hard and wear-resistant rubber, installed to block the water outlet 2 of the outlet pipe 3. In addition, the lower end of the lever 8 with the plug 11 is equipped with a L-shaped lever device in the form of a shoulder 12 connected through a hinge to the rod 13. A rod 14 is placed on the rod 13. The rod with a float can be height-adjustable depending on the required filling level of the metering tank. The rotation of the two shoulders of the lever 8 with a locking body in the form of a plug 11 is limited by the stop 15 of the bracket 7, which has a continuation in the form of a console.

A pipeline 16 is provided for supplying water to the metering tank 1, and a valve 17 is provided for controlling the amount of incoming water.

According to the embodiment (Fig. 2), the upper end of the two shoulders of the lever 8 is made using a tension spring 18, connected with an additional bracket 19 with the clamp 6.

Installation for automatic watering of plants works as follows.

The metering tank 1 through the valve 17 of the shutoff valve is filled with water, and with the help of the valve the flow rate of the water into the tank 1 is adjusted. When the water level rises, the float 14 rises. When the water level reaches the command mark in the tank 1, the lifting force of the float 14 overcomes the load weight - counterweight 10 at the end of the L-shaped two-shouldered lever 8, the water outlet 2 of the pipe 3 opens. Upon reaching the specified level, the drive L-shaped two-shoulder lever 8 with a locking member in the form of a plug 11 and the load the counterweight 10 is rotated relative to the swinging axis 9 on the bracket 7, opening a completely water outlet 2 of the outlet pipe 3, while the movement of the lower end of the pivot arm 8 is limited by the limit stop 15, the latter being connected to the console 7. These forces also overcome the force of the suction effect, which with a decrease in the level in the tank 1 weakens.

Varying the length of the shoulder 12 or the height of the rod 13, the size of the float 14, its location, you can adjust the height of the level in the tank 1, respectively, the flow of water into the pipeline connected by a system 5 of water distribution.

Further, with a further decrease in the water level under the influence of the gravity forces of the float 14 with the arm 12 with the thrust 13, as well as the gravity of the movable part of the L-shaped two-shouldered lever 8 on the swinging axis of rotation 9 and the suction effect, the lever 8 is rotated counterclockwise, which a stopper in the form of a plug 11 closes the culvert hole 2 of the outlet pipe 3, which ensures a sharp interruption of the water flow and a snug fit of the plug 11, made in the form of a hemisphere made of dense, solid and wear-resistant rubber, to the end of the pipe 3. The reservoir is closed. Then the cycle repeats.

According to the embodiment (Fig. 2), opening and closing the locking element in the form of a plug 11 on the L-shaped two-arm lever 8 and adjusting the tension of the spring 18 at the upper end of the lever 8, the lever pulls the spring 18, therefore, the drive lever 8 with the plug 11 is rotated relative to axis 9, opening the water outlet 2 of the outlet pipe 3.

Thus, the proposed installation allows you to automate the process of watering greenhouses, gardens after a certain specified time.

The connection density of the L-shaped two-shouldered lever with a load-counterweight or with a tension spring, a locking element in the form of a plug and pipe, the durability and reliability of operation and the cheapening of the proposed device is achieved by manufacturing all parts from various materials with the possibility of replacing them, for example, from plastic.

The described device has a number of technical and economic advantages compared to existing plants for watering plants. The difference lies, first of all, in compactness and small dimensions, which makes it possible to place it in one unit in the tank, where, after accumulating the estimated volume of water, it is supplied to the pipeline with a distribution system. The installation of a counterweight load or a tension spring on a rotating two-arm lever on the axis of rotation allows you to adjust the operation of the installation as a whole.

Due to the simplicity of the design, the proposed installation is reliable, it allows watering repeatedly, without human intervention for several days in automatic modes, depending on the height of the level of water filling in the tank.
