technical field

The utility model relates to underground micro-irrigation technology, in particular to underground micro-irrigation equipment.

Background technique

Micro-irrigation, also known as subsurface drip irrigation, is a high-efficiency water-saving irrigation technology developed and promoted abroad in recent years. Through the infiltration irrigation pipe buried in the active layer of the main root system of the crop, it supplies water and nutrients to the root system of the crop in a timely and appropriate amount in the form of infiltration. It is similar to the microcirculation system of blood vessels. It waters evenly and consumes the least water, saving 68% of water compared with flood irrigation; Easy management; low labor intensity; long service life.

In view of the advantages of micro-irrigation technology in saving water and fertilizer, effectively reducing crop pests and diseases, and improving the quality of agricultural and sideline products, my country has now begun to promote underground micro-irrigation technology. Micro-irrigation pipes are the core components of micro-irrigation technology. The micro-irrigation pipes currently used are prone to clogging and have the problem of uneven water seepage. In recent years, rubber-plastic seepage irrigation pipes developed by using waste The problem of low pressure capacity.

Chinese patent 200920017684.0 discloses a micro-irrigation water infiltrator, which consists of a cylindrical shell and a water outlet cover. The water outlet cover is fixed on the mouth of the cylindrical shell, the bottom wall of the water outlet cover is provided with a water outlet, and the cavity of the cylindrical shell is provided with a seepage body, and the water outlet cover and the cylindrical shell pass through Threaded connection, through practical use, the micro-irrigation water infiltrator has the problems of low pressure resistance, easy blockage, and high production cost. Therefore, the development of a micro-irrigation equipment with anti-blocking and high pressure resistance is an urgent problem to be solved in the promotion of underground micro-irrigation technology.

Contents of the invention

The utility model provides an underground micro-irrigation equipment to solve the problems of easy blockage, low compressive capacity and high production cost in existing micro-irrigation equipment, so as to achieve the purpose of preventing blockage, improving compressive capacity and reducing costs .

The utility model is achieved through the following technical solutions:

Underground micro-irrigation equipment, including water inlet pipe, air outlet pipe, main pipe, water inlet pipe and air outlet pipe are respectively connected to the main pipe through 90 degree elbow, the main pipes are connected by water supply different diameter tee, and one end of water supply different diameter tee is connected to the micro irrigation pipe. Pipe connection, the micro-irrigation pipe is vertically installed with the water inlet pipe and the air outlet pipe, and the other end of the micro-irrigation pipe is installed with a plug. The inner layer of the micro-irrigation pipe is a UPVC pipe, and the outer layer is a rubber-plastic seepage irrigation pipe. Distributed with openings. When in use, the water inlet pipe is connected to the water source. After the water flows into the main pipe, it flows into the micro-irrigation pipe through the water supply reducing tee, and then flows out from the openings distributed on the UPVC pipe in the inner layer of the micro-irrigation pipe, and finally seeps through the outer rubber-plastic irrigation pipe. The irregular fine flow channels on the wall penetrate into the soil to achieve the purpose of irrigation. When performing micro-irrigation, control the water intake at the water inlet pipe to ensure that the water flow will not overflow from the air outlet pipe.

Further, it also includes a water supply reducing pipe, one end of the water supply reducing pipe is connected to the water supply reducing tee, and the other end is connected to the micro-irrigation pipe. In specific use, there may be a problem that there is no suitable water supply reducing tee on the market due to the relatively large diameter difference between the main pipe and the micro-irrigation pipe. The water supply reducing pipe can better connect the water supply reducing tee and the micro-irrigation pipe .

The water inlet pipe and the air outlet pipe are also equipped with a top cover, and after the water supply is stopped, the top cover is used to cover tightly to prevent foreign matter from entering the pipeline and forming a blockage.

The water inlet pipe, air outlet pipe, main pipe, water supply reducer tee, water supply reducer pipe, plug and top cover are all UPVC pipe materials. During installation, the joints are fixed with PVC glue.

Compared with the prior art, the utility model has the following advantages:

(1) The combination of UPVC pipes and rubber-plastic micro-irrigation pipes as micro-irrigation pipes can enhance the pressure resistance of the irrigation pipes, solve the problem of blockage of the irrigation pipes, improve the uniformity of irrigation, and prolong the service life of the irrigation pipes;

(2) All raw materials use UPVC pipes, and the joints are fixed with PVC glue, which has low production cost, convenient installation and easy promotion.
