Abstract
The utility model relates to a curved-flow-passage microspray head. The microspray head comprises a supporting frame, a water spraying nozzle and a sprayer; the supporting frame is fixed on the outer surface of the upper part of the water spraying nozzle in a sleeving way; the upper end of the sprayer is rotatably accommodated inside a locating hole at the upper end of the supporting frame; the lower end of the sprayer is in contact with the position of the water outlet of the water spraying nozzle; the sprayer takes the shape of a reverse circular cone; a protruding part matched with the locating hole of the supporting frame is arranged at the bottom of the circular cone; at least one group of long, medium and short flow passage slots are formed on the surface of the circular cone of the sprayer; the beginning points of the long, medium and short flow passage slots are the tip of the circular cone; the length of the medium flow passage slot is 75 percent that of the long flow passage slot; and the length of the short flow passage slot is 50 percent that of the long flow passage. The multi-curved-flow-passage combined microspray head overcome the defects in the prior art and has the characteristics of large spraying radius and uniform water-spraying amount outside and inside.
Description
Technical field
The utility model relates to a kind of water-saving irrigation device, relates in particular to a kind of curve runner mini sprinkler.
Background technology
The microspray irrigation technology is a kind of advanced irrigation technique of effective adjusting crop water, and microspray irrigation adopts pipeline water delivery, sprays near ground, has significantly reduced the loss in evaporation loss and the water delivery process.Microspray irrigation is a localized irrigation in addition, reduced the invalid water consumption of part soil, thereby water saving, have energy-conservation, the high characteristics of all even quality of pouring water of pouring water simultaneously, microspray irrigation can also be in conjunction with uses such as crop foliage dressing, spray medicines, fogging degree is higher during water spray, can increase crop humidity, regulate the soil moisture, can control the humidity and the temperature on the face of land preferably, reduce the generation of disease and pest, improve quality and the output of crop, therefore, in industrialized agriculture and featured agriculture plantation, obtained using widely.Microspray irrigation is mainly used in surface irrigation, as greenhouse vegetable, grow seedlings, flower culture etc. has higher requirements to humidity, can realize crop irrigation and regulates protection ground ambient humidity or temperature, help plant growth, and can realize cleaning the effect on crop blade face.
Microspray irrigation is by the low pressure pipeline system, with less flow water is sprayed onto a kind of irrigation method that soil and plant surface are irrigated.It is a kind of new irrigation technique that progressively forms on the basis of drip irrigation and sprinkling irrigation.Current are sprayed by mini sprinkler with bigger flow velocity during microspray irrigation, be ground into tiny water droplet and drop to ground or crop blade face under the effect of air drag.Because mini sprinkler flow-out hole mouth and flow velocity be all greater than the water dropper flow velocity and the flow of drip irrigation, thereby reduced the obstruction of douche greatly.Microspray irrigation also can directly be sprayed onto crop blade face or root system soil surface on every side with irrigation water with the solubility chemical fertilizer, improves fertilising efficient, saves fertilizer amount.
That the shower nozzle that microspray irrigation is commonly used has is rotary, centrifugal, four kinds of refraction type and clearance types.
Chinese patent Granted publication CN2096420U, the clear generation of the artificial Gu of application, Granted publication day is on 02 19th, 1992, discloses " flow guiding type refraction sprinkler ".A kind of flow guiding type refraction sprinkler, it has a tapered aproll awl, in aproll awl bottom the support bar that is connected on the support is arranged, this support is positioned at the bottom center of a cylindrical housings, the nozzle of the top connecting band tapering of cylindrical housings, there is the n piece inside along the axial arranged deflector of shower nozzle, and the inner of this deflector is with contacting with the support bar surface that is positioned at the housing center.
Existing product exists spray radius little, and there are outer many interior few phenomenons in the water yield of sprinkling, and the uniformity of pouring water remains further to be improved.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of curve runner mini sprinkler, and its range is big, uniformity of irrigation water appilcation is high.
For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of curve runner mini sprinkler, it comprises support, water spout, spray body, the water spout outer surface of upper is fixed in described support socket, the upper end of described spray body is rotating to be placed in the locating hole of support upper end, and the spray body lower end touches in water spout delivery port place; Described spray body is the inverted cone body, the bottom surface of conically shaped body is provided with the protuberance with the locating hole of support coupling, the taper seat of spray body be provided with at least one group length, in, short flow path groove, this length, in, short flow path groove starting point is conical tip, make current leave spray body from different grooves, shed different positions, guaranteed the uniformity of water-spraying amount; The length of flow path groove is 75% of long flow path groove length in described, and the length of described short flow path groove is 50% of long flow path groove length.
The rooved face of described flow path groove is straight-line groove.
The bottom land of described flow path groove is the inner concave arc surface curvilinear structures.
Described length, in, the central angle alpha of short flow path groove is 60 degree, the arc length of described long flow path groove is 2～2.70cm, the arc length of flow path groove is 1.5～2.02cm in described, the arc length of described short flow path groove is 1～1.35cm, the flow channel depth difference of described different runners, long runner is darker, middle runner takes second place, short runner is the most shallow, make the current of different runners in the spray body produce different jet powers, current can be sprayed onto equably spraying range far away, in, near place, guaranteed to spray more even.
The many curves combined flow channel mini sprinkler that the utility model proposes has overcome the deficiency on the existing known technology, and it is big to have a spray radius, the inside and outside characteristics uniformly of the water yield of sprinkling.
