Abstract
The utility model relates to a water dropper for micro-irrigation. The water dropper comprises a dropper body provided with a flow pass, a water inlet and a water outlet, wherein the water inlet and the water outlet are communicated through the flow pass, the dropper body is provided with a water outlet groove, and the water outlet is communicated with a water storage groove through the water outlet groove. The water dropper is characterized in that the flow pass is a tooth-shaped flow pass, and the water outlet groove is a straight-strip-shaped groove which is formed on one side of the flow pass in parallel. According to the water dropper, the straight-strip-shaped groove increases the straight flowing length of the water outlet, and therefore negative-pressure-resistant mud absorption and plugging-resistant ability of the water dropper can be improved.
Description
Technical field
The utility model belongs to drip irrigation equipment technical field, particularly relates to a kind of slight irrigation water dropper.
Background technology
At present, in drip irrigation system when operation,, irrational management factors can affect the performance of anti-blockage of water dropper, as inappropriate screen pack, irrational construction and installation and flushing, utilizes drip irrigation system to use chemical fertilizer etc. all can to cause emitter clogging.Drip irrigation economize equipment is the core of water saving, and water dropper is the core component in drip irrigation system, and whether water dropper design has rationally determined the service life of quality, management cost and the drip irrigation equipment of drip irrigation.The anti-blockage capability that how to improve water dropper is difficult point and the hot issue of Chinese scholars research always.Technical research worker makes every effort to research and develop the water dropper that anti-blockage capability is strong both at home and abroad, as expanded emitter flow channel cross section and exploitation, has the water dropper from pre-washing function.But at present domestic and international water dropper product, because the long-pending increase of its cross section of fluid channel is limited, the long-pending size of cross section of fluid channel is still in stopping up sensitive range.Therefore, develop steady flow result good, it is very important that the water dropper that anti-blockage capability is strong seems.
Summary of the invention
A kind of performance of anti-blockage is strong, the uniform slight irrigation water dropper of water outlet for the poor technical problem of water dropper anti-blockage capability existing in solution known technology provides for the utility model.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of slight irrigation water dropper, comprise water dropper body, described water dropper body is provided with runner and the water inlet being communicated with by runner and delivery port, water dropper body is provided with delivery port groove, described delivery port is communicated with aqua storage tank by delivery port groove, it is characterized in that: described runner is flow path of gear profile, described delivery port groove is the parallel vertical bar shaped groove of being located at described runner one side.
The utility model can also adopt following technical scheme:
The both sides of described runner are respectively equipped with described delivery port groove.
The degree of depth of described delivery port groove is 0.2mm.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, the groove of vertical bar shaped has increased the direct current length of delivery port, thereby can improve anti-negative pressure suction mud and the anti-blockage capability of water dropper.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, water inlet; 2, runner; 3, delivery port groove; 4, delivery port; 5, aqua storage tank.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of slight irrigation water dropper, comprises water dropper body, and water dropper body is provided with runner 2, delivery port groove 3, water inlet 1 and delivery port 4, and water inlet 1 and delivery port 4 are communicated with by runner 2, and delivery port 4 is communicated with aqua storage tank 5 by delivery port groove 3.Above-mentioned runner 2 is flow path of gear profile, and delivery port groove 3 is the parallel vertical bar shaped groove of being located at described runner 2 one sides.The groove of vertical bar shaped has increased the direct current length of delivery port 4, can improve the anti-negative pressure of water dropper and inhale mud and anti-blockage capability.In order to make the anti-blockage capability of water dropper stronger, the both sides of runner 2 are respectively equipped with delivery port groove 3, and aqua storage tank 5 and delivery port 4 are communicated with by two delivery port grooves 3.In the present embodiment, the degree of depth of delivery port groove 3 is 0.2mm.
