[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] By analyzing the prior art, the inventors found that: when a general double-head liquid spray part and a dual-axis drive device are assembled and connected, the driving end of the dual-axis drive device needs to be inserted into the double-head liquid spray part and fixedly connected thereto, but the space in the groove for inserting the dual-axis drive device of the double-head liquid spray is very narrow, which is not convenient for the installation of the dual-axis drive device; if the groove is made large enough, a gap will be generated between the double-head liquid spray part and the dual-axis drive device, which will cause displacement and wear of the double-head liquid spray part.

[0026] Reference Figure 1 and Figure 2 , showing a structural diagram of a double spray head structure with a coupling structure provided by the present application, comprising: a double-axis driving device and a double-head liquid spraying part; the two driving ends of the double-axis driving device are respectively provided with transmission sleeves, and the transmission sleeve and the double-head liquid spraying part are detachably connected; when the transmission sleeve and the double-head liquid spraying part are connected, the driving end of the double-axis driving device rotates and drives the double-head liquid spraying part to rotate.

[0027] In the embodiments of the present application, in response to the problem that the spray heads in the prior art are not easy to install and fix, the present application provides a solution to a dual spray head structure with a coupling structure, specifically "comprising: a dual-axis driving device and a dual-head liquid spraying part; the two driving ends of the dual-axis driving device are respectively provided with transmission sleeves, and the transmission sleeve and the dual-head liquid spraying part are detachably connected; when the transmission sleeve and the dual-head liquid spraying part are connected, the driving end of the dual-axis driving device rotates and drives the dual-head liquid spraying part to rotate". By respectively arranging transmission sleeves at the two driving ends, the dual-head liquid spraying part is directly fixed to the transmission sleeve, thereby avoiding inserting the driving end into the dual-head liquid spraying part, thereby achieving the technical effect of facilitating the installation of the liquid spraying part.

[0028] Next, a double spray head structure with a coupling structure in this exemplary embodiment will be further described.

[0029] In an embodiment of the present application, the dual spray head structure comprises: a dual-axis driving device and a dual-head liquid spraying part;

[0030] The two driving ends 31 of the dual-axis driving device are respectively provided with transmission sleeves 2, and the transmission sleeves 2 and the dual-head liquid spraying part are detachably connected;

[0031] When the transmission sleeve 2 is connected to the double-headed liquid spraying part, the driving end 31 of the double-shaft driving device rotates and drives the double-headed liquid spraying part to rotate.

[0032] It should be noted that the present application avoids inserting the driving end 31 into the dual-shaft liquid spraying part by detachably connecting the transmission sleeve 2 and the dual-head liquid spraying part, which facilitates the installation of the two and also facilitates the maintenance of the driving device and the replacement of the dual-head liquid spraying part. Among them, the transmission sleeve 2 is a hollow circle, which is sleeved on the driving end 31 and fixedly connected thereto.

[0033] In an embodiment of the present application, a groove for inserting the dual-axis driving device is provided between the two nozzles of the dual-head liquid spraying part.

[0034] It should be noted that the selection of a double-headed liquid spraying part can increase the spraying range of the spray, and when the two driving ends 31 of the dual-axis driving device are inserted into the groove, the width of the groove is the same as the width between the two transmission sleeves 2. If there is a gap between the inner wall of the groove and the transmission sleeve 2, it will make it difficult to connect the two.

[0035] In an embodiment of the present application, the transmission sleeve 2 is provided with a first screw hole; a second screw hole 21 corresponding to the first screw hole is provided in the groove of the double-headed liquid spraying part, so that when the dual-axis driving device is inserted into the groove, the transmission sleeve 2 provided with the first screw hole and the double-headed liquid spraying part provided with the second screw hole 21 are fixedly connected by screws.

[0036] It should be noted that using screws to connect the transmission sleeve 2 and the double-headed liquid spraying part can facilitate the maintenance and replacement of the two; the transmission sleeve 2 and the double-headed liquid spraying part of the present application can also be connected by other means, such as welding, etc.

[0037] In addition, the driving end 31 of the dual-axis driving device of the present application does not extend beyond the transmission sleeve 2, so that the transmission sleeve 2 and the inner wall of the groove can be closely attached to each other, which is convenient for fixing the screws.

[0038] In the embodiments of the present application, Figure 3, showing a schematic diagram of the disassembly of the coupling structure of a double spray head structure with a coupling structure in the present application, the dual-axis driving device includes a dual-axis reduction motor and a transmission member 1; the dual-axis reduction motor is connected to the transmission member 1, and the two driving ends 31 are respectively connected to the transmission member 1.

[0039] It should be noted that the two ends of the transmission member 1 are respectively provided with driving ends 31, and the driving ends 31 are symmetrical to each other; the dual-axis reduction motor can control the rotation speed, and the rotation speed of the motor can be set according to actual needs to ensure uniform spraying of the liquid medicine.

[0040] In an embodiment of the present application, the dual-axis drive device is further provided with two shaft sleeves 32 and two shaft sleeve pressing blocks 3; the shaft sleeves 32 are respectively sleeved on one end of the transmission sleeve 2 close to the transmission member 1, and the shaft sleeve pressing blocks 3 are respectively sleeved on the shaft sleeves 32 and fixedly connected to the transmission member 1.

[0041] It should be noted that the volume of the double-headed liquid spraying part of the present application is much larger than the volume of the dual-axis driving device inserted into the groove part. Under the extrusion of the double-headed liquid spraying part, the transmission sleeve 2 is more likely to be displaced. The sleeve 32 and the sleeve pressing block 3 fill the distance between the transmission sleeve 2 and the transmission member 1, alleviate the impact force on the transmission sleeve 2, and prevent the transmission sleeve 2 from being displaced in the direction of the transmission member 1.

[0042] The shaft sleeve pressing block 3 is also provided with screw holes, and the shaft sleeve pressing block 3 and the transmission member 1 are fixedly connected by screws to further prevent the transmission sleeve 2 from being displaced.

[0043] In the embodiment of the present application, the portion of the dual-axis driving device inserted into the groove is provided with a motor fixing plate 4, and the two shaft sleeve pressing blocks 3 are connected to the motor fixing plate 4.

[0044] It should be noted that the motor fixing plate 4 can protect the dual-axis driving device from being bumped and damaged.

[0045] In the embodiment of the present application, a limiting device 5 is provided between the two driving ends 31 of the dual-axis driving device; the limiting device 5 is fixedly connected to the motor fixing plate 4 and limits the rotation angle of the driving end 31 .

[0046] It should be noted that the limit device 5 is a micro switch, which limits the rotation angle of the double-headed driving device, which means that before the double-headed driving device rotates to drive the spray part to spray onto the body of the spray truck, the rotation of the driving device must be stopped to prevent waste of liquid medicine and prevent the liquid medicine from damaging the vehicle body.

[0047] In an embodiment of the present application, the dual spray head structure is also provided with a single-axis drive device 12, which is arranged at one end of the transmission member 1 away from the dual-head spray part, and drives the transmission member 1 to rotate; wherein the axis of the single-axis drive device 12 is vertically arranged.

[0048] It should be noted that the single-axis drive device 12 is a single-axis reduction motor and is also provided with a limit device 5 to control the rotation angle. The dual-axis drive device 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.

[0049] In the embodiment of the present application, the double-head spray unit includes a housing, an infusion unit and a spray head; the transmission sleeve 2 is connected to the housing; the spray head is arranged on the housing and connected to the infusion unit. The double spray head structure is also provided with a liquid medicine box, and the infusion unit is connected to the liquid medicine box.

[0050] It should be noted that the shell of the double-head spray part is shaped like a microphone, with spray heads at both ends and a groove in the middle for inserting the dual-axis driving device. A mutually connected channel is provided between the two spray heads, and the wires required for the device and the infusion part pass through the channel, which can reduce the pulling on the wires and the infusion part and ensure the beautiful wiring of the device.

[0051] The liquid pesticide is contained in the liquid pesticide tank, and is transmitted to the spray head through the liquid infusion unit and sprayed out from the spray head; the liquid infusion unit includes a liquid supply pipe for guiding the liquid.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the embodiments of the present application.
