Abstract

The utility model discloses an infecting and filling rotating injecting head composed of a vertical upward injecting nozzle and a rotatable space curved surface-shaped blade piece. When the water with certain pressure is injected from the injecting nozzle, an impacting blade piece causes the blade piece to rotate around the injecting nozzle. The refraction and the centrifugal force in the process of rotating of the blade piece cause the water injected by the injecting nozzle to become small water drops and fog for being uniformly injected to a peripheral circular region. The infecting and filling rotating injecting head is suitable for flowers, lawns, nurseries, greenhouses, etc. The utility model has the characteristics of uniform injection, soft infecting and filling strength, water source saving, low cost, beauty and durability.

Description

A kind of rotating sprinkler

The utility model relates to a kind of rotating sprinkler of the usefulness of spraying.

The pattern of existing shower nozzle is varied, mainly is divided into two big classes; One class is fixed, and another kind of is rotary.Fixed sprinkler does not have rotatable parts, current penetrate through aperture or slit under pressure, by fixedly plane of refraction refraction guiding and dispersion back ejection around a certain direction or shower nozzle, from operating position, this class shower nozzle is owing to can not take into account the requirement of aspects such as dispersiveness, uniformity, range and spray regime simultaneously, thereby its result of use can not be satisfactory, and this aperture and slit are very easily stopped up by foreign material in the water and cause and use inconvenience simultaneously.Rotating sprinkler is by the refracting plates on the water slug rocking arm of nozzle ejection, make it to produce certain rotation, when rotating to certain angle, under the effect of spring force; rocking arm sets back; thus the bump nozzle body makes water spray to a certain direction or scope, because nozzle body is all wanted rotating certain angle under each bump of rocking arm; and thereby this shower nozzle can spray around it; its process is unidirectional discontinuity, from operating position, though this class shower nozzle application rate of sprinkler irrigation is big; far firing range; the bad dispersibility of water, sprays evenly inadequately, and following drowning beam diameter is bigger; thereby the water bundle is bigger to the impact dynamics on plant and ground when falling; so be not suitable for tender and lovely plant such as flowers; seedling etc., also be not suitable for narrow and small place uses such as warmhouse booth, for the sand that is not covered by plant fully; the coring that then easily makes plant is washed away by water column and exposes and cause damage; in addition, this class shower nozzle institute water requirement is bigger, and inconvenience makes full use of limited water resource.

The purpose of this utility model is to provide a kind of atomizing and dispersion effect is good, it is even to spray, the difficult rotating sprinkler that stops up and be fit to various plants and soil.

For achieving the above object, the solution that the utility model adopts is: the top that rotatable space curved surface shape blade is placed nozzle straight up, during concrete enforcement, two kinds of structural shapes are arranged: a kind of for outer ring type is arranged, another kind of is no outer ring type, has the top of its outer ring of outer ring type rotary nozzle to be equipped with a rotatable bearing, and the bottom is by rotating snare on nozzle, the rotating shaft that protrudes upward that is being connected on the rotating vane simultaneously, the upper end of this rotating shaft is fixed on the bearing; The rotating shaft that stretches out downwards that is being connected on no its rotating vane of outer ring type rotary nozzle, the lower end of this rotating shaft are fixed on the rotation circle.

Below in conjunction with accompanying drawing and enforcement side the utility model is described in further detail.

Fig. 1 has the structure chart of outer ring for the utility model.

Fig. 2 does not have the structure chart of outer ring for the utility model.

As can be seen from Figure 1, be made up of nozzle 1, blade 2, bearing 3 and outer ring 4 the outer ring type shower nozzle, nozzle 1 is a plain nozzle straight up, and its outlet diameter can be chosen below 10mm as required.Outer ring 4 is an ellipse ring body, its left-right symmetry, its bottom is enclosed within on the nozzle 1 by rotation circle 5, top is equipped with a rotatable bearing 3, when water slug outer ring 4, outer ring 4 can rotate arbitrarily, and the version, its flat shape also can adopt circle, rectangle, rhombus, the combination of circular arc line segment etc. in adopting Fig. 1 in outer ring 4.Blade 2 is a space curved surface shape blade among Fig. 1, it is stamped to form by sheet metal, a rotating shaft that protrudes upward 6 is being connected on it, the upper end of this rotating shaft 6 is fixed on the bearing 3, when water slug blade 2, blade 2 can be around the rotation arbitrarily of its this axle, blade 2 is except that the employing metal material is made, also can make by nonmetallic materials such as plastics, bending angle of its each several part and size can be according to the hydraulic pressure sizes, jet size and to range, dispersed and inhomogeneity requirement is determined, during concrete the use, nozzle centerline, the blade rotation, the blade bearing center line and the outer ring axis of symmetry coincide.

Have the thick reason of work of outer ring type shower nozzle to be: the water with certain pressure is sprayed vertically upward by nozzle 1, water slug blade 2 is after the refraction guiding and the dispersion of blade 2, make water Shu Biancheng fine liquid particles and vaporific outside sprinkling, blade 2 produces the tangential force of a horizontal direction when the impact that is subjected to water simultaneously, this power makes blade 2 do continuous unidirectional rotation around its rotating shaft 6, the centrifugal force that rotation produced of blade 2 makes water droplet become more tiny and even, guaranteed that simultaneously all directions around the shower nozzle can both obtain same spray effect, when blade 2 forwards a certain position to, impact outer ring 4 and outer ring 4 is rotated from the part of the water of blade 2 refraction, the sprinkling blind area that forms owing to blocking of outer ring 4 has been eliminated in the rotation of outer ring 4 on the one hand, also help simultaneously the dispersion of water droplet and sprinkling evenly.

There is the outer ring type shower nozzle to compare among no outer ring type shower nozzle and Fig. 1 among Fig. 2, structure is greatly simplified, it is made up of nozzle 1 and blade 2, nozzle 1 with have the outer ring type nozzle identical, on it, be with a volution 5, this rotation circle 5 can be fixed with a rotating shaft that stretches out 6 downwards around the center line rotation of nozzle 1 on the blade 2, the lower end of this rotating shaft 6 is fixed on the rotation circle 5.The thick reason of the work of no outer ring type shower nozzle has the outer ring type shower nozzle identical with shown in Figure 1 except the rotation that does not have the outer ring.

The utility model compared with prior art has following advantage:＜1〉spray evenly, Atomizing and dispersion effect are good;＜2〉application rate of sprinkler irrigation is gentle, is fit to each Plants and soil Earth;＜3〉nozzle is difficult for stopping up, and is easy to use;＜4〉cost is low, and is attractive and durable.
