Description
Technical field
The utility model is related to agricultural equipment technology fields, and in particular to a kind of Multi-vane type all standing fluid jetting head.
Background technology
Nozzle common instrument in agricultural irrigation technology.Existing nozzle can be generally divided into porous sprinkle nozzle and
In the blocked flake type of mouth spray setting catch.The nozzle of sprinkle nozzle is multi-party by the liquid of pipeline by the duct that multiple directions are set
To sprinkling, sprinkling is more uniform, but coverage area is relatively narrow.And the nozzle of blocked flake type is then by catch by the flow direction of liquid
Change, the gap location for making liquid from catch and mouth spray spills in transverse jet, has larger spraying range, but its sprinkling is equal
Evenness is relatively low, the central area in spraying range is caused to spray insufficient.Therefore, there is an urgent need for a kind of spraying ranges and uniformly of meeting simultaneously
The nozzle of degree.
Utility model content
In view of this, the utility model provides nozzle that is a kind of while meeting spraying range and the uniformity.
The purpose of this utility model is realized by following technology:A kind of Multi-vane type all standing fluid jetting head, including tube body,
There are inlet and mouth spray in the both ends of the tube body respectively, and the inside of the mouth spray is equipped with multiple radially-arranged along mouth spray
Fixed bridge and the bearing for being disposed longitudinally on mouth spray center, the bearing are fixed on mouth spray center by multiple fixed bridges;
Go out an also shaft on the outside of the fixed bridge, one end of shaft is connect with bearing, and the other end is equipped with multiple blades;On the blade
It is provided with multiple liquid through-holes;The blade is more than 0 ° by the angle of the vertical line of plane where it and the central shaft of tube body.
The realization of any one prior art, preferably pipe can be selected in the tube body.The fixed bridge can be and tube body
It is integrally formed(Such as the tube body of high molecular material, fixed bridge can be molded simultaneously in injection)Or in subsequent handling
In the inner wall of tube body is mounted on by the prior arts such as welding, snapping connection.The bearing, shaft, can bases to match
Actual demand(Such as tube body size, fluid flow factor)It determines its specification, is common knowledge, repeats no more.The blade can
The materials such as existing plastics, metal is selected to be made, the fixed form with shaft can be welding or snap connection
Deng.Liquid enters tube body, and flow to mouth spray from inlet;After liquid reaches mouth spray, stopped by blade, liquid stream pushes
Blade rotates, and the liquid on blade edge is finally made to be thrown away along its direction rotated.Since position different on blade is suffered by it
Power angle and cause not of uniform size, therefore the drop thrown away on blade have different initial velocity, cause to leave mouth spray
Liquid has multi-motion track, and equably forms a circular sprinkling region in mouth spray front.By in regulation pipe body
The flow velocity of liquid can form different size of sprinkling region with the velocity of rotation of blade.Due to being provided with liquid through-hole on blade,
Also there is liquid covering in the positive region of mouth spray, overcomes nozzle in the prior art and sprays non-uniform problem.And vane type
Structure can also avoid being blocked by sundries at mouth spray, convenient for being sprayed using the liquid of natural water area.
Further, the inner wall of the mouth spray is set there are two annular convex platform;The one end of the blade far from shaft is stretched into
Between two annular convex platform.
Annular convex platform can generate bridging effect to the one end of blade far from shaft, avoid the parsing between blade and tube wall
It is excessive and liquid is caused directly to leak out, further improve the effect of sprinkling.
Preferably, several ventilative through holes are provided on the inboard wall of tube body on the inside of the mouth spray;Ventilative through hole is on the outside of tube body
It is tilted inwardly towards mouth spray direction.
In addition, in the utility model, several ventilative through holes are provided on the inboard wall of tube body on the inside of the mouth spray.Liquid in tube body
Body flows, and drives the air flowing on the inside of ventilative through hole, the air at both ends inside and outside ventilative through hole is made to generate pressure difference(According to Bernoulli Jacob
Fluid theorem), it is final that extraneous air is promoted to enter in tube body by ventilative through hole, it is formed in the liquid in tube body a large amount of small
Bubble is split liquid, limits the granularity and density of drop ejected by strip through-hole, reduces it to plant group
The impact injury knitted.Meanwhile the dissolved oxygen amount for increasing liquid is also helped, further promote the growth of plant;Ventilative through hole is from pipe
External side is tilted inwardly towards mouth spray direction;The flow direction of ventilative through hole liquid in tube body tilts, can be to avoid pipe
Internal liquid internal pressure is excessively high and is ejected by ventilative through hole.
Preferably, its radius of the ventilative through hole is incremented by inwardly along outside.
Radius on the inside of ventilative through hole is more than the radius on the outside of it, is conducive to form lower air pressure on the inside of ventilative through hole,
Promote the entrance of gas.

Specific embodiment
In order to facilitate the understanding of those skilled in the art, the utility model is made into one below in conjunction with attached drawing and embodiment
Step detailed description:
Embodiment 1
The present embodiment provides a kind of Multi-vane type all standing fluid jetting head, as shown in Figure 1, Figure 2, Fig. 3, including tube body 1, the pipe
There are inlet 11 and mouth spray 12 in the both ends of body respectively, and the inside of the mouth spray 12 is equipped with multiple radially-arranged along mouth spray
Fixed bridge 2 and the bearing 3 for being disposed longitudinally on 12 center of mouth spray, the bearing 3 are fixed on hydrojet by multiple fixed bridges 2
12 centers of mouth;12 outside of fixed bridge goes out also a shaft 4, one end of shaft 4 and is connect with bearing, and the other end is equipped with multiple leaves
Piece 5;Multiple liquid through-holes 51 are provided on the blade 5;The blade 5 passes through the vertical line of plane where it and the central shaft of tube body
Angle be more than 0 °.Any prior art specifically can be selected in bearing 3, such as Chinese 201520331019.4 institutes of utility model ZL
Disclosed bearing and realize.
The outside of the mouth spray 12 is set there are two annular convex platform 121;The described one end of blade 5 far from shaft stretches into two
Between annular convex platform 121.
In another embodiment, it such as Fig. 4 and Fig. 5, is provided on the inboard wall of tube body of 12 inside of mouth spray several ventilative logical
