Fertilizer and water integrated drip irrigation device

Abstract

The invention discloses a fertilizer and water integrated drip irrigation device. The fertilizer and water integrated drip irrigation device comprises a water collecting box, a fertilizer tank, a stirring unit and a drip irrigation pipeline, wherein a water inlet pipe, a first water outlet pipe and a second water outlet pipe are arranged at the bottom part of the water collecting box; the fertilizer tank is composed of a circulating pipe, a stop valve, a high-pressure pump and a spray head; the circulating pipe, the stop valve and the high-pressure pump are connected with the second water outlet pipe; the spray head is mounted at the tail end of the second water outlet pipe; a plurality of branch pipes are arranged on the drip irrigation pipeline; a first side wall and a second side wall are arranged in the inner cavity of the stirring unit at intervals; a first channel and a second channel are formed among the first side wall, the stirring unit and the second side wall; a first opening is arranged on the first side wall; the first channel communicates with the second channel; a connecting pipe is arranged on the second side wall and penetrates through the first opening to communicate with a mixed liquid outlet; a second opening is arranged on the second side wall; and the connecting pipe communicates with the second channel through the second opening. The fertilizer and waterintegrated drip irrigation device provided by the invention is uniform and sufficient in fertilizer application, can realize accurate fertilizer application, can measure and control the concentrationof fertilizer application, saves fresh water resources at the same time, is environmentally-friendly, and can be extensively popularized.

Description

technical field [0001] The invention relates to the technical field of drip irrigation, in particular to a fertilizer-water integrated drip irrigation device. Background technique [0002] Drip irrigation is by far one of the most water-saving irrigation techniques for farmland irrigation. With the development of economy and society, my country's water resources are increasingly scarce. In order to save water, the country vigorously promotes drip irrigation technology in the agricultural field. But how do you fertilize crops under drip irrigation? The current existing technology is to directly pack powdered chemical fertilizers into an iron tank. There is a tubular outlet at the lower end of the iron tank. There is a hole matching the outlet on the side wall of the drip irrigation main pipe, and the outlet is inserted into the When there is water flowing through the drip irrigation pipe, the chemical fertilizer will be washed into the water and reach the roots of the crops...

AI Technical Summary

Problems solved by technology

The above method has the following disadvantages: one, the chemical fertilizer particles are easy to block the pipeline, causing partial irrigation and fertilization; two, the particles of the chemical fertilizer are large and small, and the speed of entering the drip irrigation pipeline is sometimes fast and slow, so the content of the chemical fertilizer in the water is uneven. It causes uneven fertilization and cannot implement precise fertilization; 3. For insoluble fertilizers such as potassium sulfate, diammonia, and superphosphate, the amount of fertilizer dissolved in water is small, and it is difficult to meet the needs of crop growth; the fertilization process is time-consuming, laborious, and wastes fertilizer

In addition, the existing water and fertilizer integrated drip irrigation equipment has poor fertilizer mixing effect, cannot accurately control the flow and concentration of fertilizer, and cannot regulate the application of fertilizer
