Description

A water-saving irrigation adjustable flow nozzle

technical field

The utility model relates to a nozzle, in particular to a nozzle with adjustable flow for water-saving irrigation.

Background technique

Irrigation is the main measure taken by countries all over the world to develop agriculture: as an advanced high-standard irrigation technology in water-saving irrigation, micro-spray has been adopted by more than 100 countries in the world. The low-pressure pipeline system and the special sprinkler installed at the tail (on the final pipeline) deliver the water and nutrients required for crop growth to the soil surface or soil layer near the roots of the crops evenly and accurately at a small flow rate Among them, the irrigation method that keeps the soil at the root of crops in the best state of water, fertilizer, and air can be widely used in economic crops such as fruit trees, vegetables, flowers, and medicinal materials because of its obvious advantages such as water saving, yield increase, and high efficiency. middle.

At present, most of the nozzles do not have the function of flow adjustment, which leads to the failure of irrigation to meet the needs well. Some nozzles with the function of flow adjustment have complex structures, high purchase and maintenance costs, resulting in low market promotion rate, and most of the irrigation water contains more impurities. Nozzles are prone to repeated clogging, affecting the stability of sprinkling irrigation.

Utility model content

In view of the above deficiencies, the purpose of this utility model is to provide a water-saving irrigation adjustable flow nozzle with a simple structure, which is convenient to control the flow of the nozzle, filter the water body, avoid nozzle clogging, and ensure a stable flow of the nozzle.

In order to achieve the above purpose, the utility model provides the following technical solutions: a water-saving irrigation adjustable flow nozzle, including a hollow nozzle body, the upper end of the nozzle body is provided with an external thread for connecting with the nozzle, and the bottom of the nozzle body is provided with an inner thread The adjustment column is matched with the cavity, and the adjustment column is set in the nozzle body through thread cooperation. The middle surface of the adjustment column is provided with a sealing ring, and the nozzle body on the side of the adjustment column is provided with a liquid outlet. A support rod is provided, and the top of the support rod is provided with a filtering device matching the internal cavity of the spray head.

Adjust the length of the adjusting column in the nozzle body by rotating the adjusting column, so as to adjust the size of the adjusting column covering the liquid outlet, thereby controlling the flow of the nozzle, and the filter device filters the water to avoid nozzle blockage, and completely rotate the adjusting column out of the nozzle body After that, the filter device can be cleaned to ensure the stable flow of the nozzle.

In a further optimized solution, the filter device includes a support ring matching the body cavity of the nozzle, a filter screen is arranged in the support ring, and the support ring and the support rod are connected and fixed by a connecting rod.

In a further optimized solution, a knob is provided at the bottom of the adjustment column.

Compared with the prior art, the utility model has the beneficial effects that: the utility model has a simple structure, and the length of the adjusting column in the nozzle body is adjusted by rotating the adjusting column, so as to adjust the size of the liquid outlet covered by the adjusting column, thereby controlling the spraying of the nozzle. Flow rate, the filter device filters the water body to avoid nozzle clogging, and the filter device can be cleaned after the adjusting column is completely rotated out of the nozzle body to ensure the stability of the nozzle flow.
