    -1-SHARED MOBILE FERTIGATION DEVICE FOR SURFACE IRRIGATION
    TECHNICAL FIELD The present invention belongs to the field of irrigation equipment, and more particularly, relates to a shared mobile fertigation device for surface irrigation.
    BACKGROUND At present, farmers usually apply synthetic fertilizer for field crops by spreading in practice, which 1s inconvenient to operate and difficult to fertilize precisely. To meet the requirements of precision agriculture, the integration of water and fertilizer, also known as fertigation, has been widely promoted and extended in pressurized irrigation systems. However, fertigation is less used in surface irrigation systems, because of the existing equipment is generally designed for pressurized irrigation and is difficult to be applied to surface irrigated farmland under gravity and pressureless conditions. In view of the problems that fertilisation is accomplished generally by spreading and there 1s rare fertigation equipment for surface irrigation in practice, it is highly desirable to develop a shared mobile fertigation device for surface irrigation systems. The fertigation device is designed with the frequently used electric tricycles in rural areas, and additionally equipped with an intelligent fertigation module and a photovoltaic charging module. To achieve the functional advantages of being simple and easy to operate, the device is developed based on farmers’ needs and awareness. With the pump suction fertilizer injection, photovoltaic power generation, intelligent control and other technologies, the shared mobile fertigation device not only meets the requirements of farmers for easy and precise fertilization, but also reduces the side-effect of improper fertilisation on the farmland eco-environment.

The upper part of the fertilizer tank is provided with the water inlet pipe 19, and the bottom of the fertilizer tank is provided with the water outlet pipe 20 and the drain valve 12. The water inlet pipe 19 and the water outlet pipe 20 are connected to the water delivery pipe | by a tee coupling. The fertigation pump 8 is arranged between the water inlet pipe 19 and the water outlet pipe 20. The filter 5, the first valve 10, and the second valve 7 are sequentially arranged on the water inlet pipe
    19. The third valve 9, the fourth valve 6 and the EC sensor 4 are sequentially arranged on the water outlet pipe 20. The pressure sensor 3 and the flow sensor 2 are sequentially arranged on the water delivery pipe 1. The control system includes the display screen 16, the PLC control cabinet 17 and the housing 18.

The PLC controller controls the first valve, the second valve, the third valve and the fourth valve to be opened and closed to control the water inflow, fertilizer mixing and water outflow of the fertilizer tank.
    The operation process of the shared mobile fertigation device for surface irrigation of the present invention includes: (1) System startup: The water delivery pipe | is connected to the irrigation canal (or pipeline), the power supply module is turned on, and the display screen 16 is turned on. The flow sensor 2, the pressure sensor 3, and the EC sensor 4 start to work and upload data to the PLC controller, and the data can be read by the display screen 16.
    (2) Clean water injection: Chemical fertilizer is placed in the fertilizer tank 1, and the lower liquid level electrode 13 senses no water injected. The electromagnetic first valve 10 and fourth valve 6 are opened simultaneously, and the second valve 7 and the third valve 9 are closed. The fertigation pump 8 1s started to pump water from the canal (or pipeline) into the fertilizer tank 11 through the filter S.
    (3) Stirring: When the upper liquid level electrode 13 senses that the water is injected to a certain height, the fourth valve 6 is closed, and the third valve 9 is opened at the same time. The second valve 7 is closed, and the first valve 10 is in an open state, and the fertigation device enters a self-circulating stirring condition.
    -8- (4) Fertilizer solution extraction: After stirring for a certain time (which is set by the PLC controller), the first valve 10 is closed, and the second valve 7 is opened at the same time. The third valve 9 is in an open state, and the fourth valve 6 is closed. The fertilizer solution is extracted from the fertilizer tank 11 and injected into the canal (or pipeline) through the water delivery pipe 1. (5) Water injection & mixing & fertilizer extraction: When the lower liquid level electrode 13 senses that the fertilizer solution in the tank is extracted completely, steps 2-4 are repeated until the fertigation pump is turned off. (6) When irrigation and fertigation are completed, the fertigation pump 8 is turned off. The first valve 10, the second valve 7, the third valve 9 and the fourth valve 6 are all closed. Then shut off the system power, and the PLC control terminal and the sensors stop working. Under the working condition, the system state (opening and closing of the solenoid valve, system flow, EC value, system pressure, electrode induction) can be displayed on the display screen 16. Also, the relevant parameters (mixing time, start and stop of the fertigation pump) can be set accordingly. The transportation module of the present invention adopts an electric tricycle with the photovoltaic panel 22 used as a roof. The battery pack is transformed to realize a dual power supply mode, including household power supply and solar power supply. The plug-and-play discharge adapter 25 is additionally installed so that the battery pack can supply power for the tricycle and fertigation module, and the simple modification can be done at a low cost.
    The fertigation pump 8 is arranged for three purposes, for example, used for controlling water inflow, water outflow and water circulation for mixing fertilizer.
    29.
    There is no need to use two pumps and arrange a stirring device in the fertilizer tank.
