Description

A kind of Multi-vane type all standing fluid jetting head

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 Hole 13；Ventilative through hole 13 is tilted from 1 outside of tube body inwardly towards mouth spray direction

Described its radius of ventilative through hole 13 is incremented by inwardly along outside.

It is the wherein specific implementation of the utility model above, therefore description is more specific and detailed, but can not be And it is interpreted as the limitation to the utility model patent range.It should be pointed out that for those of ordinary skill in the art, Without departing from the concept of the premise utility, various modifications and improvements can be made, these obviously replace shape Formula belongs to the scope of protection of the utility model.
