Problems solved by technology

[0002] Drip irrigation is mostly carried out by medium-frequency or high-frequency low-water (multiple irrigation with a small amount of water) irrigation method. For crops with short root systems, each irrigation can basically meet the water demand, but for crops with long root systems, a small amount of water cannot be irrigated. The deep root system affects the normal physiological water demand of crops. Although it can be compensated by increasing the irrigation time, that is, increasing the amount of single irrigation, the operating cost of the drip irrigation system is greatly increased. Therefore, the patent number: CN201921062686.1 only solves the problem of deep root system in time. The problem of irrigation, in addition, although other pressure compensation emitters, such as CN107593373B / CN206713663U / CN106171843A, adopt the solution of embedded elastic membrane labyrinth channel and solution to realize the control of water flow, and some can also set the labyrinth channel to length and width Variable, so as to control the flow of the dropper more finely, but the elastic diaphragm will remain with impurities after long-term irrigation, and the entire emitter must be disassembled when cleaning, which will cause inconvenience to maintenance
[0003] In addition, there is a big difference in the length of the root system of each crop, and because of the uneven irrigation due to the height of the terrain, although the detachable multi-section pipe can be used to achieve the dropper of the root system at different depths, but the depth of the root system is not necessarily a single section. The integral multiple of the pipe, so it is easy to insert too deep and cause waste of water resources. After inserting to a suitable depth, some water outlets on the ground may be exposed, resulting in waste of water resources. If the pipe is equipped with a personalized length, it will have a negative impact on the processing cost. , which is not conducive to mass production and the difficulty of transportation will also increase; in addition, the existing water delivery pipes are conveniently processed, and the water outlet holes on them are evenly arranged, but the water delivery pipes can only be set on one side of the root system to be drip-irrigated, so The water flow of drip irrigation in part of the outlet holes is affected by the wall of the water pipe and can only nourish the shade away from the root system, thereby reducing the effect of drip irrigation. Therefore, there is an urgent need for a root sprinkler that is suitable for a variety of crops and can be evenly irrigated and easy to clean. , for which we propose a pressure-compensated emitter inserted into the plant root zone

Abstract

The invention discloses a pressure-compensated emitter inserted into the plant root zone, which comprises an orifice-type water inlet cavity, an emitter unit body, a threaded straight-through and a sealing plug. The upper end of the orifice-type water inlet cavity passes through a first A buckle component is sealed and snapped with an orifice type water inlet cover plate, and a water inlet pipe is inserted through the middle part of the end surface of the orifice type water inlet cover plate, and the upper part of the inner cavity of the orifice type water inlet device is fixed A trapezoidal stopper is connected, and the middle part of the orifice water inlet cavity is fixedly connected with an energy-dissipating labyrinth flow channel. An elastic diaphragm is clamped between the labyrinth flow channels, the upper end of the emitter unit body is fixedly connected with a second sealing ring, and the outer wall of the emitter unit body is provided with a pressure water outlet hole, and the pressure water outlet hole is inserted into the With a filter cavity, the emitter has rich functions, is practical, and has a certain promotional value.
