The invention relates to a reducing valve in the agriculture water-saving irrigation field and discloses an irrigation multifunctional mass-flow reducing valve. The irrigation multifunctional mass-flow reducing valve comprises a valve body, a support plate, a valve rod, a valve core, a valve cap, a base, an opening-closing valve body, a spring positioning piece, a bolt and a spring. In the working state, when the upstream pressure is instable, under the actions of spring force and water pressure, the valve rod and the valve core can move up and down in the axial direction to regulate the current cross section, then different head losses of localities are caused, and the function of stabilizing the downstream pressure is achieved. According to the irrigation multifunctional mass-flow reducing valve, a throttling port is perpendicular to the water flowing direction, and the pass flow is large; the lowest end of the valve body is provided with the opening-closing valve body, through the adjustment of the opening-closing valve body, the valve core can be closely attached to the wall face of the lower side of the throttling port, and the function of closing the valve is achieved. The irrigation multifunctional mass-flow reducing valve has the advantages that the pass flow is large, the adjusting range is wide, the pressure adjusting effect is good, the assembly is convenient, and the irrigation uniformity can be greatly improved if the irrigation multifunctional mass-flow reducing valve is applied to the agriculture irrigation system; meanwhile, the delicate design of the opening-closing valve body can omit an opening-closing valve body in a pipeline, and the investment is reduced.

The present invention discloses a sprinkling irrigation system with multiple tubes capable of moving synchronous. The system comprises at least one movable branch tube, a tube supporting facility, a drawing device and control equipment, wherein a plurality of sprinkling nozzles are formed in the movable branch tubes, one end of each movable branch tube is connected with a hose, each movable branch tube is connected to a water supply main tube by the corresponding hose, and the pipeline of the water supply main tube is controlled by an electronic control valve; the tube supporting facility comprises a tube supporting line and a suspending lever, the tube supporting line is disposed on the bottom of the movable branch tubes and is used for supporting the movable branch tubes to move, and the suspending lever is used for suspending the hoses; the drawing device comprises a pulling cable for pulling the movable branch tubes, the pulling cable is connected with a driving rod and can be pulled in two directions, and the driving rod is connected with a front and back reversable variable-speed motor; and the control equipment comprises a controller, and the controller is connected with a variable-speed motor and an electromagnetic valve. The sprinkling irrigation system is reasonable in design and convenient to mount and use, can meet irrigation demands of sprinkling users of high uniformity, has functions of irrigation, humidification cooling, spraying fertilisers and pesticides and the like, and is a wide application scope.

The device provided by the present invention forms two inlets by setting two symmetrical input ports on the side wall of the mixing device housing, and two pressure regulating pipes communicating with the blade adjusting device on the side wall. And by setting clockwise and counterclockwise mixing blades with corresponding operating rods, and setting clockwise and counterclockwise actuators on the adjacent blades that dynamically change with the two inlet pressures, the adjacent blades can automatically adapt to the dynamic changes of flow rate and pressure. , thereby increasing the stability during the mixing process of fertilizer and liquid, the device has strong operability and simple structure, and is suitable for environments with high requirements for fertilizer and water irrigation uniformity. The problem of poor adaptability to changes is that the scope of application is relatively limited; at the same time, the device can adapt to the mixing conditions of water and fertilizer with different flow rates and pressures, and can meet the irrigation needs of various types of crops in different growth periods and different water and fertilizer.

The invention relates to a mobile irrigation device and method for wall green plants, comprising a base plate, a moving wheel, a water tank, a water pump and an irrigation mechanism. The lower end of the base plate is equipped with a moving wheel, the upper end of the base plate is equipped with a water tank, and the upper end of the water tank is provided with a water inlet. A water pump is installed on the upper end of the water outlet, and an irrigation mechanism is connected to the upper end of the water pump, and the irrigation mechanism is installed on the bottom plate. The working method of the mobile irrigation device for wall green plants comprises the following steps: pre-storage of water, overall movement, irrigation and water spraying, position adjustment and device cleaning. The present invention irrigates the wall green plants in a sequence from top to bottom, and the amount of water sprayed in the irrigation process tends to decrease from top to bottom, so as to avoid excessive water accumulation in the roots of the wall green plants at the lower position after irrigation. The situation that affects normal growth occurs, and when the water spray pipe moves up and down, its horizontal position can be changed back and forth within a certain range, so as to achieve the purpose of improving the uniformity of irrigation.

The invention discloses a wireless interconnection control system and method for an electric-driven reel type sprinkler irrigation machine that improves the uniformity of sprinkler irrigation. The system includes a pressure PID controller composed of a micro-processing controller module, a wireless data transmission module, a single-chip microcomputer module, and a frequency converter. And water pump motor, pressure transmitter, wireless transmission module, mobile phone APP client, encoder, pressure PID controller indirectly controls the constant nozzle inlet pressure by controlling the pressure change of the reel sprinkler irrigation machine inlet pressure, and the microprocessor controller The module is composed of a brushless DC motor and a motor controller. The speed PID controller directly controls the recovery speed of the PE pipe. The wireless transmission module communicates the inlet pressure of the nozzle and the recovery speed of the PE pipe with the client through SMS mode. After setting the corresponding parameters Automatic adjustment of working conditions is realized, and the invention improves the uniformity of the sprinkling operation of the reel sprinkler irrigation machine, realizes remote real-time and precise control of the working conditions of the reel sprinkler irrigation machine, and provides a front-end guarantee for the intelligent irrigation of the sprinkler irrigation machine.
