The sprinkler spray gun that a kind of pitch angle is adjustable
Technical field
The present invention relates to the sprinkler spray gun that a kind of pitch angle is adjustable, for regulating irrigation sprinkler current shooting angle, being applicable to carry out sprinkling irrigation work under different wind speed.
Background technology
Along with agrotechnical development, irrigation sprinkler is because its sprinkling is even, efficiency high is widely used in agricultural production.But the irrigation sprinkler used at present, its spray gun elevation-depression angle is fixed, and causes the shooting angle of current to be fixed, the impact of wind speed when therefore spray effect is subject to work to a certain extent.When wind speed is larger, the use of irrigation sprinkler is very limited, and this seriously inhibits popularization and the development of irrigation sprinkler.For addressing this problem, need to propose the adjustable sprinkler spray gun of a kind of pitch angle, to increase the flexibility of irrigation sprinkler and the adaptability to environment.
Summary of the invention
Technical problem: the object of the invention is the weak point overcome in prior art, provides the sprinkler spray gun that a kind of simple and convenient, that economical and effective, reliability are high pitch angle is adjustable.
Technical scheme: the sprinkler spray gun that pitch angle of the present invention is adjustable, comprise shower nozzle, jet pipe, flexible pipe joint is provided with between described shower nozzle and jet pipe, the connecting rod one and connecting rod three that are parallel to each other is hinged with in described shower nozzle bilateral symmetry, the bottom of connecting rod one and connecting rod three is hinged with the connecting rod two paralleled with shower nozzle, described connecting rod one is provided with the annular snap fixed with jet pipe, described connecting rod three has bar hole, connecting rod one is provided with the bolt through connecting rod three bar hole, the hinged formation parallelogram of connecting rod one, connecting rod two, connecting rod three and shower nozzle.
The described annular snap be fixed on jet pipe is 1-2; Described connecting rod one, connecting rod two, connecting rod three, pin one, pin two, pin three, pin four, screw bolt and nut are made up of stainless steel, or are attached with rush-resisting material layer.
Beneficial effect: the present invention can regulate the pitch angle of spray gun according to the wind speed size in irrigation sprinkler environment for use, compared with prior art, the shooting angle of current can be regulated, improve the adaptive capacity of sprinkler spray gun to environment, significantly improve sprinkling irrigation effect, contribute to applying of irrigation sprinkler.Its structure is simple, and easy to operate, reliability is high, is convenient to safeguard.

Fig. 1 is structural representation of the present invention.
In figure: 1-shower nozzle; 2-pin one; 3-flexible pipe joint; 4-annular snap one; 5-jet pipe; 6-annular snap two; 7-pin two; 8-connecting rod one; 9-connecting rod two; 10-pin three; 11-nut; 12-bolt; 13-connecting rod three; 14-pin four.
Embodiment
Be further described below in conjunction with the embodiment of accompanying drawing to invention:
The sprinkler spray gun that pitch angle of the present invention is adjustable, form primarily of shower nozzle 1, flexible pipe joint 3, jet pipe 5, connecting rod 1, connecting rod 29, connecting rod 3 13, flexible pipe joint 3 is located between described shower nozzle 1 and jet pipe 5, the both sides that connecting rod 1 and connecting rod 3 13 sell one 2 respectively, pin 4 14 symmetry is hinged on described shower nozzle 1, connecting rod 1 and connecting rod 3 13 are parallel to each other, the bottom of connecting rod 1 and connecting rod 3 13 is hinged with the connecting rod 29 paralleled with shower nozzle 1, described connecting rod 1 is provided with the annular snap fixed with jet pipe 5, and annular snap is 1-2.Described connecting rod 3 13 has bar hole, and connecting rod 1 is provided with the bolt 12 through connecting rod 3 13 bar hole, and bolt 12 can move up and down in the bar hole on connecting rod 3 13, through the angle of nut 11 stationary nozzle 1.By connecting rod 1, connecting rod 29, connecting rod 3 13 with shower nozzle 1 is hinged forms parallelogram, connecting rod 1, connecting rod 29, connecting rod 3 13, pin 1, pin 27, pin 3 10, pin 4 14, bolt 12 and nut 11 are made up of stainless steel, or are attached with rush-resisting material layer.Described flexible pipe joint 3 can be rubber tube, also can be plasticity bellows.
When irrigation sprinkler works, according to the wind-force size of working environment and the pitch angle of adjustable spray gun.Due to connecting rod 1, connecting rod 29, connecting rod 3 13 and shower nozzle 1 sell 4 14 respectively, pin 1, pin 3 10, the hinged formation parallelogram of pin 27, change the position of bolt 12 as required, connecting rod 1 and connecting rod 3 13 relative position are changed, thus shower nozzle 1 is changed with the angle of horizontal plane, reach the object regulating spray gun pitch angle.
