Film ditch infiltrating irrigation multiple tube
Technical field
The utility model relates to a kind of irrigation pipeline, especially relates to a kind of film ditch infiltrating irrigation multiple tube.
Background technology
Irrigate and agricultural is had great significance, China is a large agricultural country, Water Consumption in Agriculture accounts for 63% of whole water consumption, but the water resource wretched insufficiency of China, lack of water constrains the development of China's agricultural and rural economy to a great extent, along with the expansion of global warming and scale of agricultural production, the trend of China's drought and water shortage is quite severe.When irrigated farmland, a lot of water is seepage, evaporation in water delivery, water distribution, the process of pouring water, therefore its water use efficiency is lower.Furrow irrigation is topmost surface irrigation mode, and its water-saving result is remarkable, have save energy, easy and simple to handle, to water quality requirement not advantages of higher, but its uniformity of irrigation water appilcation wayward, pour water shortcoming of low quality also clearly.
It is the furrow irrigation combined with ground film coating technique that film ditch is irrigated, and it in irrigation ditch, forms furrow membrane by being applied ointment or plaster by the mulch film with water seepage hole, and irrigation water flows on furrow membrane, and infiltrates soil by fenestra.The insulation soil moisture conservation effect of mulch film the infiltrating irrigation of film ditch is had good water-saving result, irrigation water using efficiency are high, mulch film avoids irrigation water washing away soil in ditch, decrease fertilizer loss.But the infiltrating irrigation of existing film ditch affects by physical features, the gradient, and the delivery port of infiltrating irrigation pipe easily blocks, farmland still has the uneven phenomenon of irrigation to happen occasionally.
Summary of the invention
The utility model object is to provide a kind of film ditch infiltrating irrigation multiple tube, and affect greatly to solve the infiltrating irrigation of existing film ditch by landform, the gradient, infiltrating irrigation pipe delivery port easily blocks, and exists and irrigates the technical problems such as uneven.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of film ditch infiltrating irrigation multiple tube, and comprise infiltrating irrigation pipe, described infiltrating irrigation pipe tube wall is provided with multiple seepage mouth, is arranged with filter screen outside infiltrating irrigation pipe; Described infiltrating irrigation pipe one end is provided with proportioning room, and proportioning room is provided with water inlet pipe, joins fertile pipe, gas-distribution pipe, and be provided with filter in proportioning room, filter is connected with infiltrating irrigation pipe.
As preferably, described seepage mouth is aperture or narrow slit.
The utility model has that water-saving rate is high, the not susceptible to plugging advantage of infiltrating irrigation pipe.Batch mixing can be carried out to irrigation water, fertilizer etc. by proportioning room, be flowed out by the seepage mouth on infiltrating irrigation pipe tube wall by the irrigation water after metre filter.Filter screen outside infiltrating irrigation pipe pipe can prevent the impurity blocking seepage mouth outside pipe, ensures the uniformity of film ditch infiltrating irrigation.This utility model well improves the deficiencies in the prior art, has good promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.Fig. 1 is structural representation of the present utility model, and Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
As seen from the figure, this film ditch infiltrating irrigation multiple tube, comprises infiltrating irrigation pipe 1, proportioning room 4 etc.Its infiltrating irrigation pipe 1 tube wall is provided with multiple seepage mouth 2, and seepage mouth 2 is aperture or narrow slit.Filter screen 3 is arranged with outside infiltrating irrigation pipe 1.Infiltrating irrigation pipe 1 one end is provided with proportioning room 4, and proportioning room 4 is provided with water inlet pipe 5, joins fertile pipe 6, gas-distribution pipe 7, and be provided with filter 8 in proportioning room 4, filter 8 is connected with infiltrating irrigation pipe 1.
Be embedded with bottom film ditch infiltrating irrigation multiple tube ground overlay film, by the water inlet pipe 5 in proportioning room 4, join fertile pipe 6, gas-distribution pipe 7 can carry out batch mixing to irrigation water, fertilizer etc., by filter 8 filter after irrigation water flowed out by the seepage mouth 2 on infiltrating irrigation pipe 1 tube wall.Filter screen 3 outside infiltrating irrigation pipe 1 pipe can prevent the impurity blocking seepage mouth outside pipe, slows down and water speed, ensure the uniformity of film ditch infiltrating irrigation.Filter screen 3 can adopt absorbent material to make, and irrigation water can spread to pipeline surrounding, the effect of impregnation especially above pipeline.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-mentioned embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
