A drip irrigation device

Abstract

The present invention relates to the technical field of drip irrigation, in particular to a drip irrigation equipment, comprising a main pipe, which is sequentially provided with a groundwater extraction device, a filtering device, a fertilizer adding device, a master control valve, a pressure gauge, an exhaust device, a flow rate meter, check valve and shunt tube. The fertilizer adding device includes a fertilization tank, a mixing mechanism, a water inlet pipe and a discharge pipe, and the fertilization tank and the mixing mechanism are connected through a fertilization pipeline; the water inlet pipe, the mixing mechanism and the discharge pipe are arranged from left to right Connect sequentially. Beneficial effects: the present invention uses groundwater as a water supply source, and the groundwater is widely distributed and can be used whenever it is taken out. Different extraction points can be freely set according to the size of the drip irrigation area. At the same time, rainwater can be collected for utilization, and the size of the rainwater collection tank can be reduced without taking up too much equipment space. The fertilizer adding device has a mixing mechanism to make the fertilizer and water mix evenly, and the concentration can be measured and controlled, and it is adjustable for different crops.

Description

technical field [0001] The invention relates to the technical field of drip irrigation, in particular to a drip irrigation device. Background technique [0002] Drip irrigation is an irrigation method that drips the water and the moisture and nutrients required by the crops into the soil in the root zone of the crops evenly and slowly through the piping system and the irrigator installed on the capillary tube according to the water requirements of the crops. Drip irrigation does not damage the soil structure, and the water, fertilizer, air, and heat inside the soil are always kept in a good condition suitable for crop growth. The evaporation loss is small, there is no ground runoff, and there is almost no deep leakage. It is a water-saving irrigation method. The main feature of drip irrigation is that the amount of water is small, and the flow rate of the emitter is 2-12 liters per hour. Therefore, the duration of one irrigation is longer, the cycle of irrigation is short, t...

AI Technical Summary

Problems solved by technology

[0004] The above drip irrigation equipment needs to collect rainwater first and then drip irrigation. Due to the influence of rain cycle, rainwater volume and drip irrigation area, it cannot drip irrigation crops in time.

Sometimes it is not even possible to collect enough rainwater, and an additional water source is still required. If there is no backup water source, drip irrigation cannot be done in time, and the opportunity for crop growth will be missed

Moreover, the water tank is often very large due to the storage capacity requirement and takes up a lot of space.

[0005] 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
