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

In figure: 1-shower nozzle; 2-sell one; 3-flexible pipe joint; 4-annular snap one; 5-jet pipe; 6-annular snap two; 7-sell two; 8-connecting rod one; 9-connecting rod two; 10-sell three; 11-nut; 12-bolt; 13-connecting rod three; 14-sell four.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of invention is further described:
The irrigation sprinkler spray gun that pitch angle of the present invention is adjustable, mainly by shower nozzle 1, flexible pipe joint 3, jet pipe 5, connecting rod 1, connecting rod 29, connecting rod 3 13, formed, flexible pipe joint 3 is located between described shower nozzle 1 and jet pipe 5, connecting rod 1 and connecting rod 3 13 are sold respectively 1, are sold the both sides that 4 14 symmetries are 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 paralleling with shower nozzle 1, described connecting rod 1 is provided with the annular snap fixing with jet pipe 5, and annular snap is 1-2.On described connecting rod 3 13, have bar hole, connecting rod 1 is provided with the bolt 12 through connecting rod 3 13 bar holes, and bolt 12 can move up and down in the bar hole on connecting rod 3 13, through the angle of nut 11 stationary nozzles 1.By connecting rod 1, connecting rod 29, connecting rod 3 13 and shower nozzle 1 are hinged, form parallelogram, connecting rod 1, connecting rod 29, connecting rod 3 13, sell 1, sell 27, sell 3 10, sell 4 14, bolt 12 and nut 11 made by stainless steel, or be attached with rush-resisting material layer.Described flexible pipe joint 3 can be rubber tube, can be also plasticity bellows.
When irrigation sprinkler is worked, according to the wind-force size of working environment, be the pitch angle of adjustable spray gun.Because connecting rod 1, connecting rod 29, connecting rod 3 13 and shower nozzle 1 are sold respectively 4 14, sell 1, sell 3 10, sold 27 hinged formation parallelogram, change as required the position of bolt 12, connecting rod 1 and connecting rod 3 13 relative positions are changed, thereby shower nozzle 1 and the angle of horizontal plane are changed, reach the object that regulates spray gun pitch angle.
