[0024] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0025] The inventors have found through analyzing the prior art that when conventional pesticide sprayers are spraying pesticides, especially those using dual spray heads, the spraying angle of the spray is difficult to change, which will make it impossible for the sprayed liquid to simultaneously cover crops at high and low places; the pesticide cannot be sprayed evenly, and the expected inhibitory effect cannot be achieved.
[0026] Reference Figure 1 and Figure 2 , showing an internal structure diagram of a nozzle structure with adjustable spray angle provided by the present application, comprising: a dual-axis driving device, a limiting device and a liquid spraying part; the liquid spraying part is respectively provided at the two driving ends of the dual-axis driving device; the limiting device is arranged between the two driving ends of the dual-axis driving device; when the driving end of the dual-axis driving device rotates, the liquid spraying part rotates with the driving end; the limiting device limits the rotation angle of the driving end.
[0027] In the embodiments of the present application, in view of the problem that the dual nozzle structure of the prior art still has the inability to adjust the spray angle, the present application provides a solution for a dual-head spray head with adjustable angle, specifically "comprising: a dual-axis driving device, a limiting device and a liquid spraying part; the liquid spraying part is respectively provided at the two driving ends of the dual-axis driving device; the limiting device is arranged between the two driving ends of the dual-axis driving device; when the driving end of the dual-axis driving device rotates, the liquid spraying part rotates with the driving end; the limiting device limits the rotation angle of the driving end". By arranging the liquid spraying part on the driving device, the liquid spraying part rotates with the driving device, thereby achieving the effect of expanding the spray spraying angle and improving the spraying efficiency.
[0028] Next, a nozzle structure with adjustable spray angle in this exemplary embodiment will be further described.
[0029] In an embodiment of the present application, the nozzle structure includes: a dual-axis driving device 1, a limiting device 4 and a liquid spraying part 20; the liquid spraying part 20 is respectively provided at the two driving ends of the dual-axis driving device 1; the limiting device 4 is arranged between the two driving ends of the dual-axis driving device 1; when the driving end of the dual-axis driving device 1 rotates, the liquid spraying part 20 rotates with the driving end; the limiting device 4 limits the rotation angle of the driving end.
[0030] It should be noted that the dual-axis drive device 1 of the present application is a dual-axis drive motor, the driving end is the rotating shaft of the motor, the spray part 20 is fixedly connected to the rotating shaft, and is driven by the rotating shaft to rotate along the axis. At this time, the angle of the liquid sprayed by the spray part 20 will also change accordingly, thereby improving the spraying efficiency of the pesticide.
[0031] In one embodiment of the present application, the direction of the axis is set parallel to the ground, so that the liquid sprayed by the liquid spraying part 20 during rotation can reach both high and low places.
[0032] In another embodiment of the present application, the direction of the axis is arranged perpendicular to the ground, so that the liquid sprayed by the liquid spraying part 20 can cover a larger area on both sides when rotating.
[0033] It should be noted that, in order to increase the spraying range of pesticides, the present application provides two spraying parts 20, so that the spraying range is increased both horizontally and vertically, further improving the spraying efficiency of pesticides.
[0034] It should be noted that the dual-axis drive device 1 of the present application is also provided with a limit device 4, which is a micro switch, which limits the rotation angle of the driving end, which means that before the driving end rotates to drive the spray part 20 to spray onto the body of the spray truck, the rotation of the driving end must be stopped to prevent waste of liquid medicine and prevent the liquid medicine from causing damage to the vehicle body.
[0035] The micro switch has a spring sheet, which can control the switch with only a small force and is more sensitive.
[0036] In the embodiment of the present application, the liquid spraying portion 20 is cylindrical, and the rotating shaft of the dual-axis driving device is connected to the circular surface of the liquid spraying portion 20 .
[0037] It should be noted that the shape of the liquid spraying portion 20 can be changed according to the appearance of the car to make it compatible.
[0038] In the embodiment of the present application, a cavity is provided inside the liquid spraying portion 20, and a vortex generator 2 is provided inside the cavity; and a through hole is provided on the cylindrical surface of the liquid spraying portion 20.
[0039] It should be noted that, through the unique curved surface design of the blades in the vortex generator 2, the high-speed airflow forms a high-speed rotary cutting airflow under the action of the vortex generator 2, and the high-speed rotary cutting airflow can break the pesticide liquid into very small droplets and spray them out. In this way, the liquid can be sprayed more evenly and the coverage of the spray can be wider.
[0040] In an embodiment of the present application, the nozzle structure is further provided with a wind power device, and the wind power device is connected to the vortex generator 2 .
[0041] It should be noted that the wind power device is provided with a pressure chamber, in which wind power is gathered to form high-pressure wind power, and finally connected to the vortex generator 2 .

[0043] It should be noted that the infusion part passes the liquid into the liquid channel of the vortex generator 2 through the air nozzle, and the liquid medicine is sprayed from the nozzle to the outside of the liquid spray part 20; wherein, the air nozzle is a colloid to ensure that the liquid will not flow out from the connection between the liquid channel and the infusion part.
[0044] In the embodiment of the present application, there is a gap between the nozzle and the hole wall of the through hole of the liquid spraying part 20 for releasing the wind force of the vortex generator 2 .
[0045] It should be noted that the high-pressure wind force generated by the wind device also needs to be discharged from the nozzle structure, so a gap may be left between the hole wall and the nozzle, and an air outlet may also be provided in other places of the liquid spraying part 20.
[0046] In the embodiment of the present application, a vortex generator fixing block 5 is further provided in the cavity, and the vortex generator fixing block 5 is fixedly connected to the vortex generator 2 and the inner wall of the cavity.
[0047] It should be noted that, since the vortex generator 2 is subjected to high-pressure wind force during use and is easily displaced, the vortex generator 2 can be fixed in the cavity of the liquid spraying part 20 by the vortex generator fixing block 5 to prevent the vortex generator 2 from being displaced in the cavity. In addition, the vortex generator fixing block 5 can also be connected to a vortex generator tube, and the vortex generator tube is sleeved on the vortex generator 2 to further prevent the vortex generator from being displaced due to high-pressure wind force.
[0048] In an embodiment of the present application, the nozzle structure is further provided with a liquid medicine box, and the infusion part is connected to the liquid medicine box.
[0049] It should be noted that the pesticide liquid is contained in the pesticide liquid tank.
[0050] In the embodiment of the present application, the dual-axis driving device 1 is a dual-axis reduction motor.
[0051] It should be noted that the two driving ends of the dual-axis driving device 1 can rotate together or independently, and only need to be replaced with corresponding motors for driving.

[0053] It should be noted that the single-axis drive device is a single-axis reduction motor, and is also provided with a limit device 4 to control the rotation angle; the dual-axis drive device 1 and the single-axis drive device enable the double-headed spray part of the present application to rotate up and down, left and right to spray, further improving the spraying range.
