Problems solved by technology

Existing drippers are divided into microtube type, nozzle type, inner labyrinth cylinder type, patch type, etc. according to the structure, and are divided into pressure compensation type and non-pressure compensation type according to the function. Water is slowly infiltrated into the soil in the way of "water out". Although the irrigation system can be adjusted in a timely and appropriate manner through the valve opening and closing device of the irrigation system, this appropriate amount is only based on theoretical calculations or empirical summaries, not based on the soil. Therefore, the current sprinklers cannot automatically adjust the amount of dripping water according to the actual water content of the soil, nor can they automatically stop when the water content of the soil meets the appropriate water content required for crop growth.

Abstract

The present invention relates to an adaptive irrigating device for making drip-irrigation. Said adaptive irrigating device includes the following several portions: water-dripping device, shell body, water inlet, water-dripping hole, ceramic board, curved elastic film and seating cavity. Said invention also provides the concrete structure of above-mentioned every, portion, and also provides its working principle and concrete operation method.

Description

Technical field: [0001] The invention relates to an underground watering device, in particular to an adaptive underground drip irrigation emitter. Background technique: [0002] Drip irrigation is an advanced irrigation technology, and the emitter is a key component in the drip irrigation system. Its working condition directly affects the irrigation effect, cost and service life of the drip irrigation system. Therefore, the research and development of the emitter has received extensive attention. . Existing drippers are divided into microtube type, nozzle type, inner labyrinth cylinder type, patch type, etc. according to the structure, and are divided into pressure compensation type and non-pressure compensation type according to the function. Water is slowly infiltrated into the soil in the way of "water out". Although the irrigation system can be adjusted in a timely and appropriate manner through the valve opening and closing device of the irrigation system, this appropr...
