Drip irrigation equipment suitable for arid regions

Abstract

The invention relates to the technical field of agricultural irrigation, and discloses drip irrigation equipment suitable for arid regions, which comprises an irrigation box, and a side pipe is fixedly connected to the side edge, close to the lower end, of the irrigation box; an upper expansion bag is arranged at the upper end of the irrigation box, a built-in plate is arranged in the irrigation box, a pull rod is welded to the upper end of the built-in plate, the upper end of the pull rod upwards extends out of the irrigation box, a built-in expansion bag is fixedly installed at the upper end of the built-in plate, and the built-in expansion bag is located at the upper end of the built-in plate; the upper end of the built-in expansion bag is fixedly connected with a connecting pipe communicated with the interior of the built-in expansion bag. According to the device, through the upward movement process of a built-in plate, a built-in expansion bag and gas in the built-in expansion bag enter an upper expansion bag, gas in the upper expansion bag can slowly enter the built-in expansion bag, the built-in expansion bag pushes the built-in plate downwards, water in an irrigation box can be squeezed out from a side pipe, and the drip irrigation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a drip irrigation device suitable for arid areas. Background technique [0002] In the northwest region of our country, it is relatively arid and less rainy, and it is relatively vast and sparsely populated. For this reason, a small number of people take care of a large area of ​​land. In such areas, water resources are often more precious, so most of them use water-saving measures. the method of drip irrigation; [0003] However, the current drip irrigation often requires a very long pipeline to transport water from a place with a water source. In the case of drought and hot sun, the pipeline will age in a short period of time, and the long distance will waste pipeline resources. Pipe laying During the process, it is also easy to be eaten by rodents in the fields, causing the pipeline to be damaged. If the damaged pipeline cannot be found in time, it is easy to ...

[0003] However, the current drip irrigation often requires a very long pipeline to transport water from a place with a water source. In the case of drought and scorching sun, the pipeline will age in a short period of time, and the long distance will waste pipeline resources. During the process, it is also easy to be eaten by rodents in the field, causing the pipeline to be damaged. If the damaged pipeline cannot be found in time, it will easily cause a lot of waste of water resources. Relatively long pipelines require a lot of time to find damaged pipelines, and It is also extremely inconvenient to replace;
