Abstract

The utility model relates to a sprinkler head for irrigating the plants, the nursery, the garden, etc., and comprises a tube-shaped sprinkler head body with one end provided with a water inlet, and the other end being of a first water outlet in a duck mouth shape. The front end of the first water outlet is further provided with another relatively adjustable second water outlet in the duck mouth shape. When the relative spaces of the two water outlets change between two states, the spraying angle and the spraying distance can be smoothly changed from perfect to weak or from weak to perfect, thereby satisfying different using requirements.

Description

Shower nozzle

Technical field

The utility model relates to nozzle specially used to the parts, particularly sprinkling irrigation equipment of the device therefors of spraying such as crops, nursery, orchard.

Background technology

For utilizing southern dense waterway net region farmland to have the characteristics of irrigation and drainage irrigation canals and ditches, the applicant all discloses the rainer of the different portable single operation of structure in Chinese patent CN2361075, CN2378924, CN2406478, it adopts the floating general structure of boat form of built-in miniature internal combustion engine and water pump, the mouth of a river that pumps into that has filter screen is arranged on hull bottom, pump outlet connects shower nozzle by a flexible pipe, can spray to crop or plant easily, have little, in light weight, easy to operate, the economic and practical characteristics of equipment volume.It is 10 to 50 meters water pump that this rainer adopts lift usually, and used nozzle structure is similar to shower head structure.

Summary of the invention

In general, people use shower nozzle that two kinds of demands are arranged, and the one, maximum range, the water that promptly ejects is concentrated column, is used to wash away the tubers crops fruit that has earth or farm implements is washed; The 2nd, the water that ejects has bigger sector angle, is used for the spraying pouring of crop.Usually, a kind of shower nozzle can only design according to a specific requirement, such as requiring maximum jet angle or maximum ejection range.

Main purpose of the present utility model provide a kind of can be according to different applying working conditions, can carry out range easily and the firing angle ability is selected a shower nozzle of selecting for use.

Another purpose of the present utility model be this shower nozzle in use carry out function switch very convenient, and simple in structure.

For achieving the above object, the utility model adopts following technical solution.

Designed shower nozzle comprises that one one end has the tubular body of water inlet, is first delivery port of a duckbill at the other end of tubular body.Though the delivery port of this duckbill has changed the shape of streamline, current are substantially still keeping the advection state.Front end at first delivery port also is provided with another adjustable relatively duckbill second delivery port.

By above scheme as seen, the shower nozzle that provides of the utility model has adopted two adjustable relatively duckbill delivery ports.When two delivery port relative adjustment when a certain position, advection state that can feedwater flow causes change, therefore, shower nozzle can have best range, has good impulsive force, can be used for agricultural vehicle is carried out earth flushing and fruit flushing etc.; When two delivery port relative adjustment arrive the another location, can make the state of current take place sharply to change, current are after the ejection of first delivery port, and some is subjected to the extruding that stops of second delivery port, after flowing out second delivery port, form a covering of the fan, reach best firing angle effect; When the relative position of two delivery ports changes between above-mentioned two states, firing angle and range can by excellent to bad or by bad to excellent smooth change, to be fit to different user demands.

Embodiment

Followingly be described further according to most preferred embodiment of the present utility model and accompanying drawing thereof.Referring to Fig. 1, for ease of processing, tubular body is that the segmentation manufacturing combines, and is promptly combined by main pipe 10, back calotte 30 and preceding calotte 50, forms a chamber 60 between preceding calotte 50 and the back calotte 30.Adopt screw thread tightening connection between main pipe 10 and the back cover cap 30 and be equipped with sealing ring 20, adopt screw thread to flexibly connect between back calotte 30 and the preceding calotte 50, be pressed with a sealing ring 40 at connecting portion in the joint.

Referring to Fig. 2, be positioned at before second delivery port 51 on the calotte 50 and first delivery port 35 that is positioned on the calotte 30 of back be in the orthogonal state of major axis, visible second delivery port is axially being blocked first delivery port, 35 part sections among the figure, when current flowed to second delivery port 51 from first delivery port 35, the water that flows through this part section was hindered the back and is expanded the angle ejection from second delivery port 51.Because calotte 50 can rotate relative to back calotte 30 before first, when going to the coincidence of two delivery port major axis, second delivery port 51 will can not have any blocking to first delivery port, 35 sections, the current that flow through first delivery port 35 are directly from 51 ejections of second delivery port, the water of ejection has range far away, when the angle between two delivery port major axis between the two the time, can be obtained the purpose that range and firing angle effect are taken into account between above-mentioned.

Referring to Fig. 3, the main pipe left end is the water inlet 11 that joins with water pipe, and right-hand member has with the back calotte and is connected the internal thread 12 of usefulness and is used for the shoulder 13 of crush seal circle.

Referring to Fig. 4-Fig. 6, back calotte left end has the external screw thread 31 that is connected cooperation with main pipe, also have a left side to can be used to compress the shoulder 32 of sealing ring, there is the external screw thread 34 that is used for shelving the annular groove 33 of sealing ring and is connected cooperation with preceding calotte at the middle part, first delivery port 35 is at low order end, and it is seamlessly transitted to being substantially by circular cross section promptly has duckbill by elliptic jet, its long axis direction upper shed length is l, and short-axis direction upper shed length is s.

Referring to Fig. 7-Fig. 9, before the calotte right-hand member be second delivery port 51, it also is one and seamlessly transits duckbill body into elliptic jet by circular cross section that long axis direction upper shed length is L, short-axis direction upper shed length is s, and there is the internal thread 52 that is connected cooperation with the back calotte at the middle part.

Satisfy following relation between the longitudinal axis L of the major axis l of the first delivery port section, minor axis s and the second delivery port section, the minor axis S:

L＞l＞S＞s。

L=30 millimeter in this example; The l=24 millimeter; The S=18 millimeter; The s=13 millimeter.
