Root-surrounding pressure-stabilizing irrigation emitter and working method thereof

Abstract

The invention discloses a root-surrounding pressure-stabilizing irrigation emitter and a working method thereof. The root-surrounding pressure-stabilizing irrigation emitter comprises a pressure-stabilizing irrigation emitter body and a water outlet pipe connected with the pressure-stabilizing irrigation emitter body; the pressure-stabilizing irrigation emitter body comprises a pressure-stabilizing insertion piece with a water inlet and a pressure-stabilizing bearing piece with a water outlet, the pressure-stabilizing insertion piece is inserted into an inner cavity of the pressure-stabilizing bearing piece, a water-passing filtering window is arranged in the pressure-stabilizing insertion piece, and a flow channel is arranged below the water-passing filtering window; a pressure compensation cavity is formed in the pressure stabilizer bearing piece, a diaphragm groove is formed between the bottom of the pressure stabilizer inserting piece and the pressure compensation cavity, an elastic diaphragm is arranged in the diaphragm groove, and the elastic diaphragm is located on the pressure compensation cavity; a pressure compensation cavity confluence opening is formed in the pressure compensation cavity; the water outlet pipe surrounds a trunk by a circle and is provided with uniform water outlets; the pressure-stabilizing irrigation emitter body is divided into two parts and is convenient to disassemble, assemble and clean; and the flow channel structure can be of different sizes, and flow serialization is formed. According to the root-surrounding pressure-stabilizing irrigation emitter, stable irrigation emitter outflow can be achieved in blocks with different terrains, and irrigation uniformity is achieved.

Description

technical field [0001] The invention belongs to garden and agricultural irrigation, and relates to a ring-root stabilized pressure irrigation device and a working method thereof. Background technique [0002] With the improvement and improvement of living standards, people have higher requirements for fresh fruit consumption and entertainment, so the planting area of ​​fruit trees, garden seedlings and green plants in parks is gradually expanding. Since the planting and management techniques of arbor tree species are different from those of common crops, the use of common irrigation techniques is not conducive to the growth and development of arbor root systems. [0003] New water-saving irrigation technologies such as small tube outflow, drip irrigation, and micro-sprinkler irrigation are applied, but they only irrigate trees in strips or dots. The wet zone is narrow, and the roots of trees tend to grow flat along the wet zone. Subsequently, the technology was improved, us...

Problems solved by technology

Since the planting and management techniques of arbor tree species are different from those of common crops, the use of common irrigation techniques is not conducive to the growth and development of arbor root systems

[0003] New water-saving irrigation technologies such as small tube outflow, drip irrigation, and micro-sprinkler irrigation are applied, but they only irrigate trees in strips or dots. The wet zone is narrow, and the roots of trees tend to grow flat along the wet zone.

Subsequently, the technology was improved, using micro-pipes to divert water around the roots of the tree, and installing multiple micro-sprinklers or drippers on the micro-pipes, which caused waste of emitters and increased cost.

There are also special ring-root sprinklers, which are generally in the form of micro-tubes surrounding the tree roots. There are water outlets or water outlet devices on the micro-tubes, but the outflow is not uniform.

Some seedlings are planted on sloping lands, especially in areas with large terrain drops. General ring-root sprinklers cannot meet the uniformity of irrigation requirements.
