Abstract
The utility model relates to a buried irrigation emitter. The buried irrigation emitter comprises an irrigation emitter main body and a water dropper which is arranged on the irrigation emitter main body; the buried irrigation emitter is characterized in that one end of the water dropper is provided with a strip-shaped water inlet and the other end of the water dropper is provided with a water outlet window; a turbulent flow runner is arranged between the strip-shaped water inlet and the water outlet window; a tongue table is arranged in the water outlet window; a tongue-shaped sheet is arranged on the tongue table; and a tongue-shaped water outlet is formed in the irrigation emitter main body. The buried irrigation emitter provided by the utility model has the advantages of simple structure, convenience in use and convenience for maintenance and can have an effect of preventing sediments from being absorbed and root systems from invading; meanwhile, negative pressure blockage of the water dropper is effectively prevented.
Description
Technical field
The utility model relates to the agricultural water-saving irrigation equipment technical field, relates in particular to buried irrigator.
Background technology
Buried drip irrigation is a kind of new drip irrigation technique of extensively promoting in the world in recent years; Be that drip irrigation pipe is laid on below the plow layer; Water goes out through a water dropper on the ground pipe laying or an orifice flow; And under capillarity or action of gravity, the needed liquid manure of crops directly is diffused into crop root, be made for the drip irrigation mode that thing absorbs.Owing to can keep the root of the crop layer loose penetrating in its process of pouring water, reduce surface evaporation, have tangible water saving effect.Its major advantage: ⑴ water saving---there is not the ground evaporation of water; ⑵ reduce the labour---and do not need each shop to receive drip irrigation pipe in season, the damage of having avoided artificial or machinery when each season, drip irrigation pipe was received in the shop to cause drip irrigation pipe, thus prolong the service life of system; ⑶ the optimization of plant nutrition---plant nutrition is applied directly to the root of crop through irrigation system; ⑷ weeds are few---in the dry maximum minimizing of soil surface the growth of weeds; ⑸ disease is few---reduced the disease that crop is produced owing near the moist insect pest that the is caused crop, like root rot, leaf disease etc.
With compared with techniques such as surface irrigation and sprinkling irrigations, underground drip irrigation has unrivaled advantage, is water saving at present, energy-conservation irrigation method, but underground drip irrigation also exists and is prone to stop up and shortcoming difficult in maintenance.After the pipeline of pouring water was cut off the water, the hollow billet negative pressure can make the soil molecule suck the micropore of irrigator, causes obstruction, and hydrotropism's growth of root system of plant possibly cause root to invade weeper, also can cause obstruction.
Summary of the invention
The utility model technical problem to be solved provides a kind of anti-obstruction, buried irrigator easy to maintenance.
For addressing the above problem, the described buried irrigator of the utility model is made up of irrigator body and the water dropper that is located at therebetween, and it is characterized in that: an end of said water dropper is provided with said bar shaped water inlet, and its other end then is provided with the water outlet window; Be provided with turbulent runner between said bar shaped water inlet and the said water outlet window; Be provided with the tongue piece platform in the said water outlet window, this tongue piece platform is provided with tongue-like pieces; Said irrigator body is provided with the ligulate delivery port.
The table top of said tongue piece platform is the inclined-plane.
It is the filter screen of 0.6mm that said bar shaped water inlet is provided with 23 ~ 25 apertures less than said turbulent width of flow path.
The utility model compared with prior art has the following advantages:
1, owing to be provided with tongue piece platform and tongue-like pieces in the utility model, therefore, tongue-like pieces has closed trend under suction function, can play to prevent that silt is inhaled into the effect with root intrusion; It is the filter screen of 0.6mm that the water inlet of bar shaped simultaneously is provided with 23 ~ 25 apertures less than turbulent width of flow path, effectively prevents the obstruction of water dropper generation negative pressure.
2, the utility model is simple in structure, easy to use, easy to maintenance, and overall cost is low, and it is few that the later stage is managed and protected expense.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is a water dropper tongue piece opening sketch map in the utility model.
Fig. 2 is a water dropper tongue piece pipe closed condition sketch map in the utility model.
Fig. 3 is a water dropper 2D cutaway view in the utility model.
Fig. 4 is an emitter structure sketch map in the utility model.
Fig. 5 is a partial sectional view in the utility model.
Among the figure: 1-tongue-like pieces 2-turbulent runner 3-bar shaped water inlet 4-tongue piece platform.
Embodiment
Like Fig. 1 ~ shown in Figure 5, buried irrigator is made up of irrigator body and the water dropper that is located at therebetween.One end of water dropper is provided with bar shaped water inlet 3, and its other end then is provided with the water outlet window; Be provided with turbulent runner 2 between bar shaped water inlet 3 and the water outlet window; Be provided with tongue piece platform 4 in the water outlet window, this tongue piece platform 4 is provided with tongue-like pieces 1; The irrigator body is provided with the ligulate delivery port.
Wherein: the table top of tongue piece platform 4 is the inclined-plane.
It is the filter screen of 0.6mm that bar shaped water inlet 3 places are provided with 23 ~ 25 apertures less than turbulent runner 2 width.
The utility model operation principle: during duty, current flow via bar shaped water inlet 3, turbulent runner 2, water outlet window, ligulate delivery port.At this moment, the tongue-like pieces 1 at ligulate delivery port place is owing to receive water impact, and tongue-like pieces 1 is outwards opened, and current flow out thus.During off working state, current source pressure disappears, and can in the irrigator body, flow backwards; Produce negative pressure this moment; Because negative pressure absorption, this moment, the tongue-like pieces 1 of ligulate delivery port curved inwardly, and attached on the tongue piece platform 4 thereunder; Divide shutoff with the ligulate water outlet, prevent that silt stops up turbulent runner 2 in the irrigator because of the current suck-back is brought into around the irrigator.
