SHARED MOBILE FERTIGATION DEVICE FOR SURFACE IRRIGATION

The present invention provides a shared mobile fertigation device for surface irrigation, including a transportation module, a power supply module, and a fertigation module. The fertigation module includes a fertilizer tank, a fertigation pump, a control system, 5 a water delivery pipe and a base frame. The fertilizer tank, the fertigation pump, the control system and the water delivery pipe are mounted on the base frame. The upper part of the fertilizer tank is provided with a water inlet pipe, and the bottom of the fertilizer tank is provided with a water outlet pipe and a drain valve. The water inlet pipe and the water outlet pipe are connected to the water delivery pipe by a tee lO coupling. The fertigation pump is arranged between the water inlet pipe and the water outlet pipe. A filter, a first valve, and a second valve are sequentially arranged on the water inlet pipe. A third valve, a fourth valve and an EC sensor are sequentially arranged on the water outlet pipe. A pressure sensor and a flow sensor are sequentially arranged on the water delivery pipe. The shared mobile fertigation device for surface 15 irrigation of the present invention is modularly installed, which is convenient to disassemble and assemble, and it has a self-absorbing and diluting function (especially suitable for pressureless surface irrigation systems).
