Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of atomizing nozzles, and more specifically to a multi-joint nozzle of a plant protection sprayer. Background Art
[0002] A sprayer is a machine that disperses liquid into mist. It is mainly divided into agricultural, medical and other uses. Sprayers are divided into hydraulic, pneumatic and centrifugal sprayers according to their working principles. There are usually two types of nozzles for plant protection sprayers, one is a cylindrical nozzle, also called a conical nozzle, and the other is a fan nozzle. The spraying effect of the sprayer is mainly controlled by the shape and specifications of the nozzle to control the spraying uniformity. For example, the patent of prior art announcement number CN221288285U discloses a multi-joint nozzle for plant protection sprayers, which is docked with a water storage tray through a water pipe. According to the needs, a suitable number of docking sleeves are selected to dock with the drain pipe and the water distribution pipe respectively. The staff can rotate the threaded sleeve so that the threaded sleeve cooperates with the positioning ring to drive the sleeve ring to move on the surface of the spray pipe. When the spray pipe moves, the fixed ring can be pulled by the pull rod to move. The movement of the fixed ring can pull the diversion pipe to move, thereby changing the inclination angle of the diversion pipe.
[0003] When the above device is working, the pull rod is moved by moving the ring, and then the diversion pipe is bent and tilted, thereby changing the auxiliary spraying angle of the second water mist nozzle, adjusting the spraying area, and ensuring uniform coverage during spraying. It can improve the spraying efficiency to a certain extent, but it is easy to affect the uniformity of spraying when changing the spraying angle of the water mist nozzle. At the same time, when spraying a large area of vegetation, it is impossible to expand multiple nozzles, which will affect the spraying efficiency. Utility Model Content

The outer end surface of the connecting protrusion 7 is provided with an external thread, and the diverter pipe 2 and the nozzle connecting piece 4 can be connected and fixed by a locking nut 5.
[0029] like Figure 3 and Figure 4 As shown, a locking stopper 17 is provided on the outer end surface of the nozzle connector 4 at a side away from the connecting protrusion 7, a limit block 18 is provided on one side of the outer end of the locking stopper 17, and a sealing protrusion 10 is provided on one side of the inner end surface of the nozzle connector 4;
[0030] An adapting protrusion 16 is provided at one end of the nozzle connector 4 on a side away from the sealing protrusion 10, a second cross bracket 19 is provided on the inner end surface of the nozzle connector 4 on a side away from the sealing protrusion 10, and a locking nut 5 is provided on the outer end surface of the nozzle connector 4 on a side close to the locking limit block 17, and the connecting protrusion 7 is connected to the locking nut 5 by a thread, so as to facilitate the installation and removal of multiple nozzle connectors 4;
[0031] The outer end surface of the adapter protrusion 16 is provided with a sealing gasket 15, which can increase the stability and sealing of the connection between the nozzle connector 2 and the nozzle connector 4. The inner end surface of the nozzle connector 4 is provided with a first cross bracket 12 on the side close to the sealing protrusion 10, and the middle part of the first cross bracket 12 is provided with a guide support block 13, and the outer side of one end of the guide support block 13 is provided with a support spring 14;
[0032] A sealing ball plug 11 is provided at one end of the support spring 14, and the support spring 14 will push the sealing ball plug 11 toward one side of the sealing protrusion 10, so that the sealing ball plug 11 performs sealing work on the opening of the sealing protrusion 10. A support push rod 20 is provided on one side of the middle part of the second cross bracket 19, and an adaptor push plate 9 is provided at one end of the support push rod 20. When multiple nozzle connectors 4 are installed, the adaptor push plate 9 will push the sealing ball plug 11 to move it inward, so that the multiple nozzle connectors 4 are connected. The sealing ball plug 11 is a rubber material component.

The outer end face of the adapter protrusion 16 in the right viewing direction is in contact with the inner end face of the sealing protrusion 10 in the right viewing direction. The inner side structure of one end of the diverter tube 2 is the same as the structure of the inner end face of the nozzle connector 4 on the side close to the sealing protrusion 10.
[0035] Working principle of this utility model:
