Abstract
The present invention relates to a micro-irrigation suction-type douche and comprises a cushion chamber. The present invention is characterized in that a water-conducting core that passes through the wall of the douche is arranged on the cushion chamber, and the water-conducting core passes through a positioning block that is arranged inside the cushion chamber. The length of the cushion chamber is more than or equal to 2 cm and is less than 4 cm. The front end and the rear end of the cushion chamber are reduced and are connected with a junction pipe. Compared with the prior art, the present invention has the unique characteristic that the suction effect of the capillary tube of the water conducting core is used to suck the water from the pipeline so as to irrigate the crops. The structure technical parameters of the present invention are achieved from the great amount of indoor and field experiment data; therefore, the present invention can satisfy the requirement to be buried underground; especially the horizontal moisture range and the upward vertical penetration depth meet the requirement for the douche to be popularized in the field. The douche of the present invention has the advantages of water saving, high irrigation efficiency, simple structure, low cost, low working water head, good block-resistant performance, etc. thereby having higher popularization value.
Description
Technical field
Patent of the present invention relates to a kind of agricultural irrigation new technology, especially relates to a kind of little profit irrigation technique of working under the low pressure condition, and this irrigation technique realizes by micro moisting and irrigation suction type douche.
Background technology
At present, traditional flood irrigation irrigation method is also continued to use in most of area, China rural area, causes water resource to waste greatly.Along with science and technology development, irrigation technique is also being constantly brought forth new ideas and is being improved.Development high-efficiency water-saving equipment is one of key issue of developing modern agriculture, and in order to improve the availability that irrigation effect also improves water effectively, a kind of irrigation method that is applicable to dryland farming---little profit irrigation technique is by my institute's experimental study.Little profit irrigation technique is to utilize little profit irrigation system, by the irrigator of installing on buried water delivery hollow billet and the hollow billet moisture is carried to be assigned to the field near a kind of local irrigation technique of the soil profit of the drying crop root.Mainly there is the problem of following two aspects in actual applications in irrigator of the prior art.Be the hydraulic performance problem on the one hand,, cause parameters such as flow, flow velocity and ground moistening scope can not satisfy irrigator and be embedded in underground requirement because the structure and the parameter designing of irrigator are unreasonable; Be the easy blockage problem of irrigator on the other hand, cause irrigator stop up reason, mainly be to exist physico chemistry that molecule or water quality etc. cause to stop up and the hydrotropism of plant grows and causes the obstruction of emitter outlet by irrigation water.
Summary of the invention
In order to solve the problems of the technologies described above, it is good to the invention provides a kind of water-saving result, irrigation efficiency height, not susceptible to plugging micro moisting and irrigation suction type douche.
The employing technical scheme is:
Micro moisting and irrigation suction type douche, comprise a cushion chamber, it is characterized in that having the water guide core that runs through its tube wall on the described cushion chamber, be connected with the anticreep mouthpiece respectively behind the front and back end undergauge of cushion chamber, be provided with the locating piece of wearing the water guide core perpendicular to the apopore position in the cushion chamber.
The length of described water guide core is 8cm-10cm, and the water guide core accounts for aperture area than being 70%-85%
The length of described cushion chamber is more than or equal to 2cm, and less than 4cm, the internal diameter of cushion chamber is 0.8cm-1.5cm, and external diameter is more than or equal to 1.2cm, less than 2.0cm.
The length of described mouthpiece be more than or equal to 0.8cm less than 1.5cm, the internal diameter of mouthpiece is 0.4cm-0.8cm, external diameter is more than or equal to 0.6cm, less than 1.0cm.
The specification length of described locating piece is 0.3-0.5cm, and width 0.2cm-0.4cm, thickness are 0.1cm-0.3cm.
Described water guide core is a spandex low stretch yarn water guide core.Water guide core length is that to account for the aperture area ratio be 80% for 9cm, water guide core.
Described cushion chamber length is 3cm, and the internal diameter of cushion chamber is 1.0cm, and external diameter is 1.4cm.
The length of described mouthpiece is 1.1cm, and the internal diameter of mouthpiece is 0.55cm, and external diameter is 0.77cm.
The specification length of described locating piece is 0.4cm, and width 0.3cm, thickness are 0.2cm.
The present invention compared with prior art, its maximum characteristics are to utilize the capillary attaction effect of water guide core water sucking-off from pipeline, crop is irrigated, its structure and technical parameter are by drawing in a large amount of indoor and field experiment data, therefore can satisfy being embedded in underground requirement, the requirement that irrigator is promoted in the field is highly all satisfied in particularly horizontal wetted perimeter and infiltration vertically upward.Advantages such as the present invention has water saving, irrigation efficiency height, and is simple in structure, that cost is low, working head is low, the anti-clogging performance is good have higher popularization and application values.
