[0002] Agricultural drones are specialized drones used in agricultural production. They can precisely apply agricultural inputs like pesticides and fertilizers based on the actual conditions of the farmland and the growth needs of the crops. They are characterized by high efficiency, precision, and intelligence. The spraying mechanism of an agricultural drone is one of its core components, responsible for precisely applying pesticides, fertilizers, and other agricultural inputs to the fields.

[0003] The spraying mechanism of agricultural drones mainly sprays pesticides, fertilizers, etc. through nozzles. Different crops and farmland environments have different requirements for spraying. Since the angles and spacing of the nozzles on the drone's spraying mechanism are fixed, it cannot adapt to the spraying needs of different crops and farmlands, resulting in poor spraying effects. As a result, some areas will be over-sprayed and some areas will be under-sprayed, affecting crop growth. Utility Model Content

[0004] The purpose of the utility model is to propose an agricultural drone spraying mechanism to solve the problem that the existing agricultural drone spraying mechanism has poor adaptability and cannot adapt to the spraying needs of different crops and farmlands, resulting in poor spraying effect.

[0006] The spray head can be moved along the axial direction of the fixed pipe and rotated around the axis of the fixed pipe through an adjusting mechanism.

[0007] As a further description of the above technical solution: the adjustment mechanism includes a connecting assembly connected to the fixed pipe, and a connecting plate for connecting the nozzle is provided on the connecting assembly through the mounting plate.

[0008] As a further description of the above technical solution: the connecting assembly includes a fixing seat and a clamping seat that cooperate with each other to form a clamp structure, the fixing seat and the clamping seat are connected by connecting bolts, and a fastening assembly is provided on the clamping seat.

[0010] As a further description of the above technical solution: a strip groove is provided on the outer surface of the fixing tube, and a clamping strip that matches the strip groove is provided on the pressing plate.

[0011] As a further description of the above technical solution: a clamping block is provided at one end of the connecting plate through a mounting bolt, and the clamping block cooperates with the connecting plate to form a clamp structure for clamping the nozzle.

[0012] As a further description of the above technical solution: the other end of the connecting plate is provided with a connecting screw that passes through the bottom of the mounting plate, and the connecting screw is provided with a locking nut that abuts against the surface of the mounting plate.

[0013] As a further description of the above technical solution: the number of the nozzles is at least two.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figures 1-6 This embodiment provides an agricultural drone spraying mechanism, comprising a fixed tube 1 connected to the drone via a mounting frame 2, a pipe joint 3 provided in the middle of the fixed tube 1, a nozzle 5 provided on the fixed tube 1 via an adjustment mechanism 4, and the nozzle 5 connected to the fixed tube 1 via a connecting hose 6, and the number of nozzles 5 is at least two;

[0026] The nozzle head 5 can be moved along the axial direction of the fixed pipe 1 and rotated around the axis of the fixed pipe 1 through the adjustment mechanism 4 .

[0027] In the utility model, the fixed pipe 1 of the spraying mechanism is fixed on the drone through the mounting frame 2, and then the pipe joint 3 is used to connect it to the pipeline of the medicine box on the drone, so that the fixed pipe 1 is connected to the liquid pump of the medicine box of the drone. When spraying pesticides or fertilizers, the adjustment mechanism 4 is used to adjust the spacing or angle of the nozzles 5 according to the spraying requirements of different crops and farmlands, so that the spraying mechanism can meet the growth requirements of the crops during spraying. The nozzle 5 and the fixed pipe 1 are connected through the connecting hose 6. The connecting hose 6 has a certain flexibility, so that the connection between the nozzle 5 and the fixed pipe 1 can be ensured when the nozzle 5 moves. The pesticide or fertilizer in the drone medicine box is sent into the fixed pipe 1 under the action of the liquid pump, and then enters the nozzle 5 through the connecting hose 6 to realize the spraying work.

[0028] Specifically, such as Figure 1-Figure 3 As shown, the adjustment mechanism 4 includes a connecting component 41 connected to the fixed pipe 1, and a connecting plate 43 for connecting the nozzle 5 is provided on the connecting component 41 through the mounting plate 42. The connecting component 41 includes a fixing seat 411 and a clamping seat 412 that cooperate with each other to form a clamp structure, and the fixing seat 411 and the clamping seat 412 are connected by a connecting bolt 413.

[0029] Among them, when the adjusting mechanism 4 is connected to the fixed tube 1, the fixing seat 411 and the clamping seat 412 of the connecting assembly 41 are respectively clamped on the fixed tube 1, and then the fixing seat 411 and the clamping seat 412 are connected by the connecting bolts 413, and the mounting plate 42 is connected to the bottom of the fixing seat 411. The clamp structure formed by the fixing seat 411 and the clamping seat 412 can facilitate the disassembly and assembly of the adjusting mechanism 4 and the fixed tube 1, thereby facilitating maintenance.

[0030] Specifically, such as Figure 3-Figure 5 As shown, a fastening assembly 414 is provided on the clamp seat 412, and the fastening assembly 414 includes an adjusting bolt 4141 that passes through the clamp seat 412, and the bottom of the adjusting bolt 4141 is movably connected to a pressure plate 4142 that cooperates with the fixed tube 1, and a strip groove 11 is provided on the outer surface of the fixed tube 1, and a clamping strip 4143 that cooperates with the strip groove 11 is provided on the pressure plate 4142.

[0031] When the spacing or angle of the nozzles 5 needs to be adjusted, the adjusting bolt 4141 is screwed to move the adjusting bolt 4141 on the clamping seat 412, thereby driving the pressure plate 4142 to move. The pressure between the pressure plate 4142 and the fixed pipe 1 becomes smaller. At this time, the connecting assembly 41 can be moved axially on the fixed pipe 1 and rotated around the axis of the fixed pipe 1 to adjust the spacing and angle of the nozzles 5. After the position of the nozzles 5 is adjusted, the adjusting bolt 4141 is screwed in the opposite direction to press the pressure plate 4142 tightly against the surface of the fixed pipe 1, and the fixed pipe 1 is clamped and fixed in cooperation with the fixing seat 411.

[0032] The strip groove 11 on the fixed tube 1 and the clamping strip 4143 at the bottom of the pressure plate 4142 are used to limit the connection component 41 in the direction around the axis of the fixed tube 1. When the connection component 41 is fixed on the fixed tube 1, the clamping strip 4143 of the pressure plate 4142 is stuck in the strip groove 11 of the fixed tube 1, thereby preventing the nozzle 5 from rotating in the circumferential direction during operation, ensuring that the angle of the nozzle 5 is fixed.

[0033] Specifically, such as Figure 2 and Figure 6 As shown, one end of the connecting plate 43 is provided with a clamping block 431 through a mounting bolt 432, and the clamping block 431 cooperates with the connecting plate 43 to form a clamp structure for clamping the nozzle 5, and the other end of the connecting plate 43 is provided with a connecting screw 433 that passes through the bottom of the mounting plate 42, and the connecting screw 433 is provided with a locking nut 434 that abuts against the surface of the mounting plate 42.

[0034] Among them, when installing the nozzle 5, the nozzle 5 is clamped in the groove at one end of the connecting plate 43, and then the clamp block 431 is connected to the connecting plate 43 through the mounting bolt 432. The clamp block 431 and the connecting plate 43 form a clamp structure, thereby fixing the nozzle 5. The connecting plate 43 with a clamp structure design can facilitate the disassembly and assembly of the nozzle 5, and thus facilitate the cleaning and maintenance of the nozzle 5. When installing the connecting plate 43 and the mounting plate 42, the connecting screw 433 is passed through the mounting plate 42, and then the locking nut 434 is locked and fixed. It can facilitate the loading and unloading of the connecting plate 43 and facilitate the maintenance and repair of the entire adjustment mechanism 4.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
