Abstract

The invention discloses a refraction type micro-nozzle, which adopts the technical scheme that the refraction type micro-nozzle comprises a refraction body, wherein a cone is arranged at the center of the lower surface of a refraction body disc and is arranged in a water pipe hole in a micro-nozzle frame, water distribution grooves are distributed on the surface of the cone and are communicated with refraction grooves on the lower surface of the refraction body disc, and the groove depth and the groove width of the refraction grooves distributed on the lower surface of the refraction body disc are different. Compared with the prior art, the invention has the remarkable advantages of spraying bar shape and irregular round shape.

Description

A kind of refraction type mini sprinkler
Technical field:
The present invention relates to a kind of microspray irrigation technology, particularly a kind of refraction type mini sprinkler.
Background technology:
Microspray irrigation is a kind of advanced person's a water-saving irrigation technique, and mini sprinkler is the key equipment of the terminal water distribution in the microspray irrigation system.The refraction type mini sprinkler is a kind of mini sprinkler of simple in structure, routine that movable part is few and easy to use, the refraction type mini sprinkler that uses at present.The zone of spraying is circular, semicircle; Yet; The greenbelt that is shaped as irregular cycle such as strip in the zone that need spray and ellipse etc., above-mentioned shower nozzle can cause the subregion to respray to this irregular cycle zone sprinkling, and the shortcoming that does not spray in other zones.
Summary of the invention:
The purpose of this invention is to provide a kind of a kind of refraction type mini sprinkler that sprays bar shaped and irregular cycle.Technical solution of the present invention is; Comprise refractile body; It is characterized in that: the lower surface center of said refractile body disk is provided with the water pipe hole that a cone places the mini sprinkler frame; Be distributed with bypass channel on the surface of this cone and be connected with refracted slot on the refractile body lower disk surface, the groove depth and the groove width of the refracted slot that distributes on the said refractile body lower disk surface are inequality.Have the groove depth of refracted slot of two phase obliques the darkest in the refracted slot that distributes on the said refractile body lower disk surface, and groove width is the narrowest, shoals gradually and groove width broadens gradually in the groove depth of the refracted slot of these two obliques.The present invention and prior art relatively have the remarkable advantage that can spray bar shaped and irregular cycle.
Description of drawings:
Fig. 1 is the structural representation of refraction head, and Fig. 2 is the upward view of Fig. 1, and Fig. 3 is the combination sketch map of refractile body of the present invention and mini sprinkler.
The specific embodiment:
Can only spray the shortcoming of respraying, leaking spray that circle, semicircular area cause in order to solve existing refraction head; The refraction structure of birefringence head of the present invention for this reason improves as follows, and promptly the annular surface of the disk 2 that is connected with taper seat therewith of the surface of the cone 4 at the center, lower surface of refractile body 1 is provided with the degree of depth refracted slot different with width 3,5, and is darker and groove width is narrow more according to the degree of depth of refracted slot; The distance rule far away more of under identical hydraulic condition, being sprayed; Can design the multiple non-circular refractile body that is shaped as that sprays the zone, be that the groove depth of the level trough of two symmetries in lower surface of refractile body is the darkest like the distribution of the refracted slot of concrete refractile body of the present invention; Groove width is the narrowest; And the groove depth of perpendicular two refracted slots of refracted slot is the most shallow therewith, and groove width is the wideest, and the groove depth of the refracted slot between above-mentioned two perpendicular refracted slots shoals gradually; Groove width is then broadened by narrow gradually, the zone that this refractile body sprayed be shaped as ellipse.The refractile body that sprays bar shaped (rectangle) has its groove depth of refracted slot of two phase obliques the darkest, groove width is the narrowest; The angle of these two refracted slots is inversely proportional to the width that sprays distance and bar-shaped zone; And the groove depth of the refracted slot between the refracted slot of above-mentioned oblique and groove width shoal gradually and broaden; Make it to spray into rectangle (being bar shaped), adopt this refractile body that the bar shaped greenbelt is sprayed, respray and to leak the area of spray very little.The assembling of refractile body is, the cone of refractile body is placed water pipe 6 holes of mini sprinkler frame 7, and the cylinder of its upper end is fixed in the hole of mini sprinkler top of the trellis, and the pipe fitting 8 of the bottom of above-mentioned water pipe 6 is connected (referring to Fig. 3) with feed pipe.The present invention has only done improvement to the refractile body in the mini sprinkler, and other parts do not change.

Claims (2)

1. refraction type mini sprinkler; Comprise refractile body; It is characterized in that: the lower surface center of said refractile body disk is provided with the water pipe hole that a cone places the mini sprinkler frame; Be distributed with bypass channel on the surface of this cone and be connected with refracted slot on the refractile body lower disk surface, the groove depth and the groove width of the refracted slot that distributes on the said refractile body lower disk surface are inequality.
2. a kind of refraction type mini sprinkler according to claim 1; It is characterized in that: have the groove depth of refracted slot of two phase obliques the darkest in the refracted slot that distributes on the said refractile body lower disk surface; And groove width is the narrowest, shoals gradually and groove width broadens gradually in the groove depth of the refracted slot of these two obliques.
