(57) Abstract:Usage: in the agricultural industry, in particular in automated pivot circular actions for optimal soil moisture. The inventive automated sprinkling machine circular action contains discharge pipe 1 with herasaponin body 2, system 3 emergency protection chamber connected with the upper adminpanel cavity of hydrocele 4, which controls herasaponin body. The valve 6 controls kinematically connected with the sensing elements 12 tensiometer 13, which is installed in the root layer of soil at the control sites, characterizing the entire irrigated array served by sprinkling machine with regard to relief and soil factors. The machine provides full automation of management by directly controlling the moisture content of the soil tensiometers and their inclusion in the control system of irrigation, thereby linking it on and off directly with soil moisture. 2 Il. The invention relates to agriculture and can be used in irrigated agriculture for optimal seriescom mode, as well as linking on and off the pivot directly with soil moisture almost needs of plants.In Fig. 1 shows the overall diagram of the automated sprinkler circular steps; Fig.option 2 design of the sensing element of the tensiometer and the valve controls in the kinematic relationship.Automated sprinkler machine consists of the discharge pipe 1 valve body 2, which provide water supply to sprinkler machine system 3 emergency protection, hydraulically communicating with the upper namebrands cavity of hydrocele 4, which controls the shut-off body 2, and has an exit to the atmosphere through the dose of 5. The valve controls 6, consisting of a body 7, two water conveyance channels 8 and 9, the elastic diaphragm 10, the locking rod 11, through the threaded connection is connected to sensor 12 sensor 13 query irrigation. Water conveyance channels 8 hydroline 14 are connected between themselves and with the pressure pipe. Water conveyance channels 9 hydroline 15 are also connected with each other and with the upper namebrands cavity of hydrocele 4.The sensor 13 mounted on the control pad the elements 12, which consist of housing 18, the elastic membrane 19 and the return spring 20, working in compression.Automated sprinkling machine operates as follows.Before the first irrigation on selected reference sites porous elements 16 are installed in the root layer of soil. Under the action of return spring 20 through the membrane 19, the locking rod 11, the aperture 10 water conveyance channel 8 is blocked. Depending on soil moisture within a closed system of sensors 13 creates negative pressure, perceived elastic membrane 19 and the return spring 20 of the sensing element 12. When the vacuum reaches a predetermined level set by the tension of the spring 20, and the corresponding soil moisture, which should start watering (reached the threshold valve controls 6), the membrane 19 begins to move down, freeing the locking rod 11, which in turn through the aperture 10 releases the output water conveyance channel 8. From the discharge pipe 1 hydroline 14 and water conveyance channel 8 water starts to enter the water conveyance channel 9, and hydroline 15 in the upper namebrand cavity, hydrocele 4 and 3 emergency protection codevalue pressure, which will switch hydrocele on the opening of the valve body 2. Sprinkling machine and join in the work.After watering the first sector and, accordingly, the first control pad with sensors moisture in the rooting zone of the soil will increase, which will decrease the vacuum inside the closed system of the sensor. Elastic membrane 19 under the action of the spring 20 will begin to move up and through the locking rod 11 and the diaphragm 10 will block water conveyance channel 8. The same thing will happen with sensors after irrigation of the following sectors, respectively, and control plots. After all water conveyance channels 8 will be blocked, the water flow in the upper namebrand cavity, hydrocele 4 stops. Water from the emergency protection system through a dose of 5 will result in the atmosphere. The pressure in the upper namebrands cavity of hydrocele 4 will be reduced to zero. Hydrocele switch for closing the shut-off body 2. The machine will stop.Next watering will begin when soil moisture again reaches the specified level on any of the control sites and when the water will begin to flow into the upper namebrand cavity, hydrocele 4, where the labor movement needed to switch the strain gauge and valve controls allow you to set the threshold control valve to a predetermined soil moisture and change in a very wide range of soil moisture by increasing or decreasing the tension of the return spring 20 by screwing in or screwing out on the screw connection of the housings 7 and 18 (Fig.2). AUTOMATED SPRINKLING MACHINE CIRCULAR STEPS, including the pipeline on the supporting trucks with emergency safety system, connected by a communication line with the control cavity, hydrocele hydraulic stop valve on the inlet line to the machine and duty, the output of which is communicated with the atmosphere, and the valve controls connected hydraulically with the system of emergency protection and kinematically associated with the sensing elements of the sensor query irrigation, characterized in that the sensors query irrigation is supplied with each porous element placed in the soil at the corresponding control site and the sensitive element of each sensor is made in the form prescribed in the housing spring-loaded membrane, interacting with the valve stem controls, with diaphragm spring working in compression, and the cavity in the diaphragm by the spring hydraulically connected to the porous element.
