Uniform-spraying water outlet valve for agricultural greenhouse irrigation

Abstract

The invention provides a uniform-spraying water outlet valve for agricultural greenhouse irrigation, and relates to the technical field of irrigation valves. The uniform-spraying water outlet valve for agricultural greenhouse irrigation comprises a water conveying pipe, the top of the water conveying pipe is in threaded connection with a pesticide bottle, a pesticide adding hole is fixedly connected to the position, below the pesticide bottle, of the top of the water conveying pipe, an upper flow limiting rod is slidably connected to the interior of the water conveying pipe, a spraying head is fixedly installed at the bottom of the water conveying pipe, and the top in the spraying head is rotationally connected with a rotary drum in a limiting manner. According to the uniform-spraying water outlet valve for agricultural greenhouse irrigation, self-adjustment of the pesticide dosage according to the water pressure is achieved, pesticide distribution is more uniform, the dosage is more appropriate, the pesticide applying effect is improved, the spraying range of water flow can be kept certain, the phenomena that irrigation is repeated and irrigation cannot be achieved in a certain area are avoided, the water flow is prevented from dripping downwards in a concentrated manner, so that the irrigation uniformity is improved, and the irrigation quality is ensured.

Description

technical field [0001] The invention relates to the technical field of irrigation valves, in particular to a water outlet valve for uniform spraying for agricultural greenhouse irrigation. Background technique [0002] Greenhouse planting is a new type of scientific planting method. By controlling the temperature, humidity and other parameters of the environment inside the greenhouse, many anti-seasonal crops can be obtained. In the process of greenhouse planting, it is inevitable to set up spraying devices inside the greenhouse. It is used for irrigating crops, and the outlet valves of the existing sprinkler devices are all equidistantly distributed inside the greenhouse to irrigate the crops in different areas. The spray range of the water outlet valve changes, and then it is prone to the phenomenon of repeated irrigation or irrigation in a certain area, and after the irrigation is completed, the accumulated water at the water outlet valve is also easy to concentrate and d...

[0002] Greenhouse planting is a new type of scientific planting method. By controlling the temperature, humidity and other parameters of the environment inside the greenhouse, many anti-seasonal crops can be obtained. In the process of greenhouse planting, it is inevitable to set up spraying devices inside the greenhouse. It is used for irrigating crops, and the outlet valves of the existing sprinkler devices are all equidistantly distributed inside the greenhouse to irrigate the crops in different areas. The spray range of the water outlet valve changes, and then it is prone to the phenomenon of repeated irrigation or irrigation in a certain area, and after the irrigation is completed, the accumulated water at the water outlet valve is also easy to concentrate and drip downward, which will lead to insufficient spraying. The phenomenon of uniformity reduces the effect of irrigation, and when spraying pesticides, people pour the pesticides into the pipes of the irrigation device, which is prone to uneven pesticide content in different water outlet valves, and it cannot be automatically adjusted according to the level of water pressure. Adjusting the dosage of pesticides makes the distribution of pesticides uneven and the dosage is uncomfortable, which reduces the effect of pesticide application
