Be provided with internal thread on the exhalant canal of lower house, a top of regulating dropper is provided with external screw thread and is spun on the internal thread of lower house exhalant canal, and the upper surface of regulating dropper is provided with effluent trough.
Further improve, described adjusting dropper outer surface middle part is provided with spacing preiection, prevents from regulating dropper and revolves to such an extent that get on very much to damage the current stabilization sheet.
Further improve, described spacing preiection is polygon again, the end face part on each limit or all be provided with the water flow mark; Both make things convenient for turn to regulate dropper, conveniently determined again discharge.
Preferred described current stabilization sheet is the flexible silicon film.
Further improve, the inner peripheral surface of the interior annular protrusion on the upper circular groove of described lower house is provided with many convex tendons radially again, can prevent from regulating dropper and be in when the next, and the distortion downwards of current stabilization sheet blocks the exhalant canal of lower house.
The utility model is regulated dropper owing to the exhalant canal at lower house is rotary with one, regulate dropper and can adjust up and down the position with respect to lower house, the upper surface of regulating dropper is provided with effluent trough, by cooperating of current stabilization sheet and described effluent trough, just can change again the water flow of effluent trough by adjusting the relative position of regulating dropper upper surface and current stabilization sheet lower surface, the water flow of effluent trough is adjustable continuously, therefore uses quite flexible, is more suitable for the meticulous irrigation of crops.
On the other hand, because of water flow of the present utility model adjustable continuously, just can adapt to different growing stage crop irrigation needs, in drip irrigation system, do not need the frequent drip head, both reduced the input of drip irrigation system, also reduce and change the required cost of labor of drip head, finally reduce irrigation cost.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.
Fig. 1 is to shown in Figure 7, the drip head that a kind of flow is adjustable, comprise upper shell 1, lower house 2, the centre of upper shell 1 is provided with intake tunnel 11, the centre of lower house 2 is provided with exhalant canal 21, the lower end of upper shell 1 is provided with lower circular groove 12 and is communicated with intake tunnel 11, the upper end of lower house 2 is provided with circular groove 22 and is communicated with exhalant canal 21, in the middle of being locked together mutually, the upper end of the lower end of upper shell 1 and lower house 2 accompanies current stabilization sheet 3, the upper surface that the lower circular groove 12 of upper shell 1 is provided with an annular protrusion 13 and current stabilization sheet 3 fits, be arranged at intervals with four on the described annular protrusion 13 and cross the mouth of a river 131, be provided with interior annular protrusion 23 on the upper circular groove 22 of lower house 2, outer annular protrusion 24 and the excessively water damping passage 25 that jointly surrounds with current stabilization sheet 3 lower surfaces, the described water inlet end of crossing water damping passage 25 is communicated with the described mouth of a river 131 of crossing, and the described water side of crossing water damping passage 25 is communicated with the exhalant canal 21 in the middle of the lower house 2;
Be provided with internal thread on the exhalant canal 21 of lower house 2, a top 41 of regulating dropper 4 is provided with external screw thread and is spun on the internal thread of lower house 2 exhalant canals 21, and the upper surface of regulating dropper 4 is provided with effluent trough 42.
Described adjusting dropper 4 outer surfaces middle part is provided with spacing preiection 43; Described spacing preiection 43 is polygon, and the end face part on each limit is provided with water flow mark 431.
Described current stabilization sheet 3 can be selected the elastic silica gel sheet.
The inner peripheral surface of the interior annular protrusion 23 on the upper circular groove 21 of described lower house 2 is provided with three convex tendons 231 radially, can prevent that the excessive exhalant canal 21 lower house 2 of current stabilization sheet 3 distortion from blocking.
But also many convex tendons of relative set on the outer peripheral face of the interior annular protrusion 23 on the upper circular groove 21 of described lower house 2 and the inner peripheral surface of outer annular protrusion 24, the effect of increased water flow damping.
Operation principle of the present utility model is as follows, in conjunction with shown in Figure 2, water enters by the intake tunnel 11 of upper shell 1, cross the mouth of a river 131 from four and flow through the water inlet end that flowed into water damping passage 25 through the side of current stabilization sheet 3, because the downward distortion of current stabilization sheet 3 is large when intake pressure is large, when the distortion that intake pressure hour current stabilization sheet 3 is downward little, the size that can regulate water damping passage 25 by the effect of current stabilization sheet 3, thus guarantee the stable of water flow.
When adjusting dropper 4 upwards is screwed into upper, the lower surface of current stabilization sheet 3 is pushed down the upper surface of regulating dropper 4 and is made the water flow of effluent trough 42 minimum, when regulating progressively backspin of dropper 4, the water flow of effluent trough 42 progressively strengthens, break away from the lower surface of current stabilization sheet 3 when the upper surface of regulating dropper 4 after, the water flow of effluent trough 42 is maximum.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
