Abstract

The utility model relates to a novel nozzle, which is a sprinkler plant in farmland water conservancy irrigation. By aiming at the abuse of poorer near-range sprinkling effect when the nozzle makes spray irrigation at present, an atomizing slot is arranged on an auxiliary spray nozzle, and simultaneously a water outlet hole of the auxiliary spray nozzle is caused to form an included angle with an auxiliary spray pipe, and thereby, the near-range sprinkling uniformity is effectively improved in spray irrigation.

Description

A kind of new type nozzle

Technical field under the utility model is the rainer during irrigation and water conservancy is irrigated.

At present, the shower nozzle that domestic many shower nozzle manufacturer produces all exists the closely relatively poor shortcoming of rainfall distribution uniformity, seriously affects the spray effect of sprinkling irrigation.

The purpose of this utility model is that a kind of new type nozzle will be provided, to solve the existing technical deficiency of shower nozzle.

The purpose of this utility model is achieved in that the apopore of secondary nozzle and secondary jet pipe shape in an angle, and on secondary nozzle, open one the atomizing groove, the secondary jet pipe of while shower nozzle and the joint low certain altitude of the joint of standpipe than main jet pipe and standpipe, like this, when spraying, closely spray effect is good.

The purpose of this utility model is to overcome the closely relatively poor drawback of rainfall distribution uniformity of existing shower nozzle, opens an atomizing groove on secondary nozzle, and makes the apopore of secondary nozzle and secondary jet pipe shape in an angle, and can making closely, rainfall distribution uniformity increases substantially.

Concrete structure of the present utility model is further specified by drawings and Examples:

Description of drawings:

Fig. 1: a kind of new type nozzle structural representation.

Fig. 2: secondary nozzle structural representation.

Fig. 3: atomizing groove structural representation.

Fig. 4: bilateral atomizing groove structural representation.

Among Fig. 1-4: 1 is sprayer body; 2 is rocking arm; 3 chew for main jet; 4 is the main jet pipe; 5 is standpipe; 6 is stage clip; 7 is rocker arm shaft; 8 is priming lever spring; 9 is secondary nozzle; 10 are the atomizing groove; 11 is secondary jet pipe; 12 is base; 13 is inlet segment; 14 is the inlet opening; 15 is external screw thread; 16 is turning point; 17 is water exit end; 18 is apopore.

1 one kinds of new type nozzles of embodiment are chewed [3], main jet pipe [4], standpipe [5], stage clip [6], rocker arm shaft [7], priming lever spring [8], secondary nozzle [9], secondary jet pipe [11], base [12] etc. by sprayer body [1], rocking arm [2], main jet and are formed.Secondary nozzle [9] is that boundary's branch is done inlet segment [13] and water exit end [17] two parts with turning point [16], and inlet segment [13] is made up of inlet opening [14] and external screw thread [15] etc.; Water exit end [17] is made up of apopore [18] and atomizing groove [10] etc.The central point that crosses of secondary jet pipe [11] and standpipe [5] is lower than the central point that crosses of main jet pipe [4] and standpipe [5].On secondary nozzle [9], inlet opening [14] are circular straight hole, and its center of circle is positioned at the center in inlet segment [13] cross section, and the center of this center and secondary jet pipe [11] coincides, and also can parallel.Apopore [18] can be circular straight hole, also can be turning point [16] one end diameters and the unequal taper circular hole of other end diameter, locates to connect with inlet opening [14] in turning point [16]; The center line shape of the center line of apopore [18] and inlet opening [14] in an angle.On water exit end [17], have an atomizing groove [10], the inboard and the apopore [18] of atomizing groove [10] connect, and outer openings is in the outer rim of water exit end [17].The width of atomizing groove [10] can be equidistantly, also can be not equidistant, and its length can be isometric or slightly short with apopore [18].Secondary nozzle [9] matches with internal thread on the secondary jet pipe [11] by external screw thread [15], is fixed on the secondary jet pipe [11].

Embodiment 2 is symmetric points with apopore [18] on the water exit end [17] of secondary nozzle [9], and respectively there is an atomizing groove [10] both sides of apopore [18].

It is a straight hole that apopore [18] on the embodiment 3 secondary nozzles [9] and inlet opening [14] connect, and the diameter at straight hole two ends can equate, also can be unequal, and the center line shape of straight hole and secondary jet pipe [11] is in an angle.
