Abstract
The invention discloses a rocker arm reciprocating type lawn spray head with self-controlled distance. The rocker arm reciprocating type lawn spray head with self-controlled distance comprises a rocker arm (1), a spray head (2) and a gear ring (3), wherein the gear ring (3) is mounted on the rocker arm (1); the gear ring (3) is of a tapered thin-wall hollow structure; an uneven tapered groove is formed in the wall surface of the gear ring (3); the rocker arm (1) rotates to drive the gear ring (3) to rotate. A spray head water outlet can change in a rotary process of the uneven groove of the gear ring (3) driven by the rocker arm, and according to a mass continuity equation, the sprayed-out water column flow velocity changes correspondingly, so that the distance change is realized.
Description
Technical field
The present invention relates to a kind of rocking arm reciprocating automatic control journey lawn nozzle, belong to sprinkler irrigation technique field.
Background technology
Sprinkling irrigation refers to special pipe-line system and equipment pressure water to be delivered to irrigated plot and be ejected into and forms a kind of irrigation method that fine liquid particles is spread across field in the air.Sprinkling irrigation, as a kind of Novel irrigation mode, has water saving, soil protection structure, regulates terrestrial climate and not by advantages such as landform restrictions, be at home and abroad widely used in recent years.There is a lot of problem in this irrigation at present: due to the problem that the northern strong wind duration is long and wind speed is large, spray irrigation system many times all can not normally run in the application; Except the bulk greenery patchess such as lawn, the pouring of other vegetation is all the mode adopting broad irrigation, and time-consuming water wasting, also easily causes soil compaction; At the noon that The sun is shining fiercely, spray irrigation system, also in work, is easy to allow the water droplet be sprayed onto on plant leaf blade play the effect of convex lens, blade of burning like this, and then damage plant; Spray irrigation system has just quit work soon or has also just had rainfall when work sometimes, wastes so beyond doubt to the one of water resource.
Present lawn nozzle on the market mainly contains two classes: one is Rocker arm spray head, and one is pulsation shower nozzle.
The common feature of this two classes lawn nozzle is: the Periodic Rotating that can realize nozzle, thus makes current spray to all directions on lawn.But also have the shortcoming that outstanding, that is exactly to realize the automatic adjustment to water spray distance: because water export speed is higher, and in the ejection of very narrow pencil, so often spray a lot at a distance, and be seldom sprayed onto nearby.
This shortcoming is a kind of waste greatly to water resource, and spray effect is also had a greatly reduced quality.
Summary of the invention
For the deficiencies in the prior art, the present invention has set up change outlet device respectively on the basis of existing rocker-arm lawn nozzle, overcome existing lawn nozzle cannot realize spraying the automatic shortcoming regulated of distance, make lawn nozzle automatically can periodically regulate water spray distance on one side by one side reciprocating rotary, thus reach the object of " evenly sprinkling, water-saving and synergistic ".Rocker-arm lawn nozzle is the metal structure that a kind of function ratio is more single, and its weak point is that sprinkling is far and near non-adjustable, and spraying range is fixed.The operation principle of rocker-arm lawn nozzle is the current impact rocking arm of spout injection, makes rocking arm turn over an angle, and rocking arm is in turning course, and oppositely impact spout reaches the object changing and spray direction.The sprinkling distance of this shower nozzle is non-adjustable, and spraying range is fixed, and the uniformity can not meet this condition.Corrective measure is the increase in a speed-changing ring be connected with rocking arm, is reached the object realizing distance and change by the water column flow velocity changing spout ejection.
For achieving the above object, the technical solution used in the present invention is a kind of rocking arm reciprocating automatic control journey lawn nozzle, and this shower nozzle comprises rocking arm 1, shower nozzle 2, speed-changing ring 3; Speed-changing ring 3 is arranged on rocking arm 1, and described speed-changing ring 3 is conical thin-wall hollow-core constructions, and the wall of speed-changing ring 3 has uneven cone tank; The rotation of rocking arm 1 drives speed-changing ring 3 to rotate.Because shower nozzle delivery port is through the change of the uneven groove of speed-changing ring 3 in rotation process that driven by rocking arm, can obtain according to quality continuity equation, the water column flow velocity of ejection also can respective change, thus realizes the change of distance.
The material of described speed-changing ring 3 adopts aluminium alloy.
Compared with prior art, the present invention has following beneficial effect.
The present invention serves the object improving rainfall distribution uniformity, under the prerequisite meeting fountain height, is conducive to shortening spraying time, thus reaches the object of water saving.In addition, the solution of the present invention does not need external force to drive, and part amendment amplitude is little, is beneficial to and realizes producing in enormous quantities on existing basis.
Accompanying drawing explanation
Fig. 1 is the original structure of rocker-arm lawn nozzle;
Fig. 2 is the rocker-arm lawn nozzle structure after repacking;
Fig. 3 is the structure chart of speed-changing ring.
In figure: 1, rocking arm, 2, shower nozzle, 3, speed-changing ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As Figure 1-3, the conical thin-wall hollow parts of speed-changing ring 3 one wall thickness only 2mm, but also uneven groove to be opened on its wall.
For shower nozzle 1, through measuring, the spout of shower nozzle 1 and the angle of horizontal direction are 23 °, and because spout is circular, the current that spout sprays itself and spout axis have the subtended angle of ± 2.5 °.
When actual measurement must be sprayed, nozzle location is A (0.01m, 0.23m)
Calculate the situation when nozzle exit velocity is v=15m/s below.
Simulate the situation from the current of spout ejection when not reequiping, pick-up point scope is (17.2365,18.1862), sprays situation meet relatively good with reality.
Realize sprinkling when muzzle velocity changes to 15m/s by 5m/s after repacking, spraying range is (2.23m 18.19m).
Claims (2)
1. a rocking arm reciprocating automatic control journey lawn nozzle, is characterized in that: this shower nozzle comprises rocking arm (1), shower nozzle (2), speed-changing ring (3); Speed-changing ring (3) is arranged on rocking arm (1), and described speed-changing ring (3) is a conical thin-wall hollow-core construction, and the wall of speed-changing ring (3) has uneven cone tank; The rotation of rocking arm (1) drives speed-changing ring (3) to rotate; Because shower nozzle delivery port is through the change of speed-changing ring (3) uneven groove in rotation process that driven by rocking arm, can obtain according to quality continuity equation, the water column flow velocity of ejection also can respective change, thus realizes the change of distance.
2. a kind of rocking arm according to claim 1 reciprocating automatic control journey lawn nozzle, is characterized in that: the material of described speed-changing ring (3) adopts aluminium alloy.
