Abstract

The utility model discloses a refractive micro sprinkler; the utility model has the technical scheme that: the refractive micro sprinkler comprises a refractive body; a cone body which is arranged in the center of the lower surface of a disk of the refractive body is arranged in a water pipe hole in a micro sprinkler frame; bypass channels are distributed on the surface of the cone body and communicated with refraction slots in the lower surface of the disc of the refractive body; and the depths and the widths of the refraction slots which are distributed in the lower surface of the disc of the refractive body are different. Compared with the prior art, the refractive micro sprinkler has the significant advantage that strip-shaped and irregular circular shapes can be sprayed.

Description

A kind of refraction type mini sprinkler
Technical field:
The utility model 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 the utility model provides a kind of a kind of refraction type mini sprinkler that sprays bar shaped and irregular cycle.The technical solution of the utility model 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 utility model 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 refractile body of the utility model and the combination sketch map of 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 the utility model birefringence head improves as follows for this reason, 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 the concrete refractile body of the utility model; 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 utility model has only been 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.
