The blocking-proof emitter is provided with the symmetrical two water outlet cavities and the symmetrical double channels, so that water supply failure due to blockage of the labyrinth channel of a single emitter is effectively avoided.
Description
Technical field
The utility model relates to a kind of drip irrigation equipment of agricultural production application, relates in particular to a kind of water dropper that has the anti-clogging function.
Background technology
Drip irrigation be through the low pressure pipeline system be installed in the water dropper on the capillary, the root that water that crop is needed and nutrient are transported to crop carries out localized irrigation.Drip irrigation is one of water-saving irrigation mode the most effectively; It is under the situation of not destroying soil structure; The growth indexes such as moisture, temperature and humidity that soil is inner maintain within the required scope of good growth; Evaporation loss is little and can not produce surface runoff, does not also almost have the situation of percdation.
Water dropper is an important components in the drip irrigation equipment, and the moisture of conveying and nutriment are sprayed onto the root of crop through water dropper.The obstruction of water dropper is a main common problem during current drip irrigation is used, and serious obstruction also possibly cause the drip irrigation system can't normal operation, even scraps.
It is varied that water dropper stops up the generation reason, contains silt, organic substance, microorganism or chemical sediment in the water that main cause is to carry.Materials such as silt finally cause blocking dropping head under in water dropper, slowly constantly accumulating.In addition, certain crop can be planted in water dropper outlet below, and the capillary root of crop also is than being easier to get into water dropper.In case the capillary root of crop gets in the water dropper, can cause the minimizing of water dropper water yield, and the capillary root of these entering can't clear completely.
The utility model content
The purpose of the utility model provides the novel drip irrigation of a kind of structure and uses water dropper, can effectively reduce the generation of stopping state, and in the capillary root of crop got into water dropper, the capillary root that can avoid existing avoided occurring the anhydrous phenomenon that goes out.
To achieve these goals; The technology that the utility model adopts is a kind of anti-clogging water dropper; It is characterized in that; Comprise water inlet filter window on the water dropper body, labyrinth flow-path, two water chambers and screening table, said two water chambers are symmetricly set on the two ends of water dropper body, are communicated with through said labyrinth flow-path between said two water chambers; Also be provided with " U " shape backflow labyrinth flow-path on the said water dropper body, an end of said " U-shaped " backflow labyrinth flow-path is arranged on labyrinth flow-path and water chamber junction, and the other end is communicated with water chamber; Said water inlet filtering window is communicated with labyrinth flow-path; Said screening table is arranged on water dropper body back.
In the above-mentioned anti-clogging water dropper that provides, the said water dropper back side is provided with the loss of weight groove.
In the above-mentioned anti-clogging water dropper that provides, said labyrinth flow-path is provided with the extension slot that is connected with the filter window of intaking.
In the above-mentioned anti-clogging water dropper that provides, said water inlet filter window is arranged at the center of water dropper body.
In the above-mentioned anti-clogging water dropper that provides, be provided with two labyrinth flow-paths between the said symmetrical water chamber.
In the above-mentioned anti-clogging water dropper that provides, the two ends of said " U-shaped " backflow labyrinth flow-path are arranged on labyrinth flow-path and water chamber junction.
In the above-mentioned anti-clogging water dropper that provides, said labyrinth flow-path is along water dropper center line symmetry.
The anti-clogging water dropper that the utility model provides adopts the design of symmetric double water chamber, symmetric double runner, effectively avoids single water dropper to stop up the situation that can't supply water that causes because of labyrinth flow-path.

Embodiment
A kind of block-resistant type drip irrigation that the utility model provides is used water dropper, comprises water inlet filter window, labyrinth flow-path, water chamber and screening table on water dropper body, the water dropper body.Also be provided with the backflow labyrinth flow-path on the water dropper body, institute's backflow labyrinth flow-path is arranged on labyrinth flow-path and water chamber junction.Vertical two ends of water dropper body are provided with symmetrical water chamber, are provided with labyrinth flow-path between the symmetrical water chamber.Labyrinth flow-path is provided with the extension slot that connects the water inlet filter window, and extension slot will flow into the labyrinth runner by the water that the water inlet filter window gets into.
Through concrete embodiment a kind of block-resistant type drip irrigation of the utility model is explained in detail with water dropper below, so that better understand the utility model, but following embodiment does not limit the scope of the invention.
As shown in Figure 1, on water dropper body, be provided with into water filter window 2, labyrinth flow-path 3, water chamber 4 and screening table by the hard plastics manufacturing.The water dropper body is flat incorporate structure, is provided with into water filter window 2 in water dropper body center, and water inlet filter window 2 is the net palisade.Respectively be provided with symmetrical water chamber 4 at vertical two ends of water dropper body, be provided with two labyrinth flow-paths between the symmetrical water chamber 4.Between the symmetry water chamber 4 labyrinth flow-path more than two can be set also, this is very favourable for flowing of water body.On labyrinth flow-path 2, be provided with the extension slot that connects water inlet filter window 2.The labyrinth flow-path both direction gets into water chamber 4 to the water that gets into from water inlet filter window 2 simultaneously along both sides.Be provided with backflow labyrinth flow-path 1 in labyrinth flow-path 3 and water chamber 4 junctions.When in the water chamber 4 tamper being arranged, can utilize backflow labyrinth flow-path 1 to realize the circulation of water body.Reverse when growing into intake antrum 2 as the capillary root of crop etc. along the water source, can under the guiding of labyrinth flow-path, get in the anticlogging backflow labyrinth 1, and can not influence the water body outflow.Select for use symmetric double water chamber 4,3 designs of two labyrinth flow-path can effectively prevent the situation that single water dropper is blocked, can also prevent effectively that single labyrinth flow-path from stopping up the situation that can not in time supply water.
Shown in Fig. 2 and 3, the adhesive surface 7 of water dropper is an arc surface, and promptly the upper surface of water dropper is an arc surface.The size of arc surface diameter is identical with the diameter of the irrigate band that is bondd, and has enlarged the adhesive surface of water dropper and irrigate band, avoids occurring the situation that irrigate band impression when tying up causes drip irrigation pipe to be broken.Be provided with screening table 6 at water dropper body back.Be provided with loss of weight groove 5 at the water dropper body back side, when significantly reducing the production materials, also can have increased the pliability and the intensity of water dropper.
The anti-clogging water dropper that the utility model provides adopts the design of symmetric double water chamber, symmetric double runner, effectively avoids single water dropper to stop up the situation that can't supply water that causes because of labyrinth flow-path.
More than the specific embodiment of the utility model is described in detail, but it is as example, the utility model is not restricted to the specific embodiment of above description.To those skilled in the art, any equivalent modifications that this practicality is carried out with substitute also all among the category of the utility model.Therefore, impartial conversion and the modification under spirit that does not break away from the utility model and scope, done all should be encompassed in the scope of the utility model.
