A variable variable high anti-clogging emitter and irrigation method

Abstract

The invention discloses a variable variable high anti-clogging water dispenser and a water irrigation method, which comprises an upper shell and a lower shell, the upper shell and the lower shell are fixedly connected, the top surface of the upper shell is set as a plane, and the plane is provided with For the water outlet, the bottom surface of the upper shell is provided with a groove communicating with the water outlet, and the groove is in the shape of a truncated cone; the lower shell includes a flow channel part and a water outlet part, both of which are recessed and embedded in the lower shell On the upper surface of the upper shell, one end of the flow channel is provided with a number of side-by-side water inlet channels, and the other end is connected with the water outlet. On the side wall of the L-shaped sinking platform; an elastic body flow channel is fixed between the upper shell and the lower shell; this scheme automatically adjusts the change of the elastic body flow channel structure in the flow channel through the change of the working water pressure, and then realizes irrigation The variable adjustment of the flow rate of the emitter improves the anti-clogging performance of the emitter, and has the function of automatically flushing the physical blockage substances inside the emitter.

Description

technical field [0001] The invention relates to the technical field of drip irrigation, in particular to a variable-variable high-blockage-resistant irrigation device and an irrigation method. Background technique [0002] Drip irrigation is an advanced irrigation method that can not only achieve high efficiency and water saving, but also achieve significant improvement in quality and efficiency. With the increasingly prominent problem of water resource shortage in my country, drip irrigation technology has developed rapidly in China. Along with it, Drip irrigation technologies for low-quality water such as Yellow River diversion irrigation and recycled water drip irrigation have also developed rapidly, which has greatly improved the water resource utilization rate of low-quality water such as reclaimed water and even waste water, and made a significant contribution to the sustainable development of my country's water resources. The emitter is the core component of the drip i...

AI Technical Summary

Problems solved by technology

The emitter is the core component of the drip irrigation system. In the low-quality water drip irrigation technologies such as the Yellow River diversion irrigation and the recycled water drip irrigation, due to the complex composition of the water quality, impurities such as sand, sludge, and microorganisms are easy to deposit, agglomerate, and adhere to the irrigation water. In the narrow flow channel of the sprinkler, the blockage of the emitter is relatively common, which seriously restricts the in-depth development of drip irrigation technology.

In the field of underground drip irrigation, the burial depth of the emitter is relatively large, and the outflow of the emitter is in a slow dripping state. It is difficult to rely on soil capillary action to guide the water to the root zone of the crop seedlings, resulting in the problem of difficult emergence; in addition, in saline-alkali areas , the existing drip irrigation and salt pressing method provides a good environment for the growth of crops, but there are still problems such as small water output, resulting in small leaching area and poor salt pressing effect

Therefore, it is very urgent to invent an emitter with the characteristics of high anti-clogging, large flow rate and adjustable outlet state, in order to solve the high clogging rate of inferior water drip irrigation emitters in the existing drip irrigation technology, and the difficulty of underground drip irrigation at the seedling stage. And drip irrigation salt leaching effect is not good and other problems

[0003] In the prior art, Patent No. 202011259298.X discloses a variable emitter, which can open the second flow channel to relieve the blockage when blockage occurs, and can also achieve the purpose of increasing the height of the wetting front; the emitter proposed by this invention The internal structure is complex. When cleaning the blockage, direct flushing cannot be realized, and the water flow of other channels must be used for flushing in disguise, and the flushing effect is not clear. In addition, the emitter is difficult to match with the existing emitter production line, and mass production is difficult. High production cost, difficult promotion and application
