technical field

The invention relates to the technical field of agricultural implements, in particular to a hydraulically driven fertilization and irrigation device.

Background technique

Water and fertilizer integration technology is a modern agricultural management technology that integrates water-saving irrigation and efficient fertilization. The integration of water and fertilizer is to use the pressure system (or the natural drop of the terrain) to mix the soluble solid or liquid fertilizer according to the soil nutrient content and the law and characteristics of the fertilizer requirement of the crop species, and mix the fertilizer solution together with the irrigation water through the controllable pipeline. The system supplies water and fertilizer. After the water and fertilizer are mixed together, drip irrigation is formed through pipes and drippers, evenly, regularly, and quantitatively, infiltrating the growth area of the root system of the crops, so that the main root system soil is always kept loose and suitable for water content. At the same time, according to different Vegetables need fertilizer characteristics, soil environment and nutrient content; vegetables need water in different growth periods, and the law of fertilizer needs is designed according to the needs of different growth periods, and the water and nutrients are regularly and quantitatively provided to crops directly in proportion.

When the water flows through the cavity, the water turbine 5 is driven to rotate, and the impeller 6 of the water pump is driven to rotate under the action of the transmission shaft, thereby driving the impeller 6 of the water pump to rotate. The liquid in the pump body rotates with the impeller 6. Under the action of centrifugal force, the liquid in The outlet is thrown out by the impeller 6, and the speed of the thrown liquid gradually slows down in the diffusion chamber of the pump body. After the liquid is thrown out, a vacuum low-pressure area is formed at the center of the impeller 6, and the liquid in the fertilizer suction pipeline 9 is affected by the external atmospheric pressure. Down, it flows into the water pump 2 through the inlet of the water pump 2.
