Further, the level-one jet pipe includes a main jet pipe, two connecting tubes for being respectively arranged on main jet pipe both ends, described It is connected between main jet pipe and connecting tube via a three-way water segregator;The second level jet pipe connection is set in the outside of connecting tube.
Further, it is connected via an inlet tube with spray tank in the middle part of the top surface of the main jet pipe, the bottom surface of main jet pipe Middle part opens up level-one spray hole.
Further, one end bottom on the second level jet pipe far from connecting tube offers second level spray hole, close to connection One end inner wall of pipe is provided with cricoid inward flange;In the connecting tube far from main jet pipe end port outer edge be provided with to The cyclic annular outward flange limited is abutted against with inward flange, the diameter of the outward flange and the diameter of inward flange are identical.
Further, sealing ring is provided between the inward flange and outward flange.
Further, level-one spray hole and second level spray hole are all connected with spray head.
Further, the level-one jet pipe and second level jet pipe are PP-R pipe.
Compared with prior art, the utility model has the effect that the utility model is simple and reasonable for structure, spray boom tool There is the function of auto-extending, it is convenient to operate, and facilitates high-efficient homework, it is numerous that high degree solves the disassembly of plant protection drone spray boom Trivial, not portable problem.
Detailed description of the invention:
Fig. 1 is the organigram of the utility model embodiment.
In figure:
1- spray tank;2- level-one jet pipe;3- level-one spray hole;4- second level jet pipe;5- seal plug;6- second level spray hole; 7- main jet pipe;8- connecting tube;9- three-way water segregator;10- inlet tube;11- inward flange;12- outward flange;13- spray head.
Specific embodiment:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of Telescopic spray lance of plant protection drone of the utility model, including middle part are connected with spray tank 1 Logical level-one jet pipe 2 offers level-one spray hole 3 on the level-one jet pipe 2, and the both ends of level-one jet pipe 2, which are respectively communicated with, to be arranged with A piece second level jet pipe 4, the port on the second level jet pipe 4 far from 2 end of level-one jet pipe are provided with seal plug 5, and second level jet pipe 4 exists Medical fluid pushes lower and level-one jet pipe 2 to form sliding pair, the i.e. ejection outward under the action of water pressure of second level jet pipe 4, the second level jet pipe 4 On offer second level spray hole 6.
In the present embodiment, the level-one jet pipe 2 includes a main jet pipe 7, two connecting tubes for being respectively arranged on 7 both ends of main jet pipe 8, it is connected between the main jet pipe 7 and connecting tube 8 via a three-way water segregator 9;The connection of second level jet pipe 4 is set in connecting tube 8 outside.
In the present embodiment, the three-way water segregator 9 is copper side double loose joints three-way water segregator, and three interface mouth diameters are equal It is specifically used to be customized according to pesticide etching characteristic for 20mm.By the way that three-way water segregator is arranged between main jet pipe and connecting tube, It can play the role of improving structural strength, avoid leading to structure shakiness since pipeline is too long, generating shaking.
In the present embodiment, it is connected via an inlet tube 10 with spray tank 1 in the middle part of the top surface of the main jet pipe 7, main jet pipe Level-one spray hole 3 is opened up in the middle part of 10 bottom surface.
In the present embodiment, one end bottom on the second level jet pipe 4 far from connecting tube 8 offers second level spray hole 6, close One end inner wall of connecting tube 8 is provided with cricoid inward flange 10;Far from the port outer edge at 7 end of main jet pipe in the connecting tube 8 It is provided with to abut against the cyclic annular outward flange 12 limited, the diameter and inward flange 11 of the outward flange 12 with inward flange 11 Diameter it is identical.When the ejection outward under the action of water pressure of second level jet pipe 4, top is stopped when abutting against to inward flange 11 with outward flange 12 Only, the function of auto-extending jet pipe is realized.
