Description

Technical Field

[0001] The invention relates to the technical field of drone spraying, and in particular to a drone spraying device for spraying pesticides. Background Art

[0002] Pesticide spraying drones, also known as plant protection drones, are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, and are used for pesticide spraying operations on crops.

[0003] Existing pesticide spraying drones consist of three parts: a flight platform, a navigation flight control, and a spraying mechanism. The spraying operation is achieved through ground remote control or navigation flight control, thereby playing a role in repelling insects.

[0004] After the existing pesticide spraying drone has been operating for a period of time, the per-acre usage of the aircraft will change, that is, the per-acre usage will be inaccurate. The main reason is: after the drone has been operating for a long time, the aircraft's medicine box will be blocked by medicine, and if the medicine is blocked, the diameter of the spray pipe will be smaller than the actual one, resulting in the actual per-acre usage being smaller. Although a filter net or high-density stockings is added to the feeding port of the medicine box to filter the liquid medicine, when the pesticide is configured, on the one hand, there will be uneven configuration of the liquid medicine, which will cause precipitation in the medicine box. On the other hand, for some pesticide preparations, such as suspension concentrates, sedimentation is prone to occur in the medicine box, that is, the upper layer gradually becomes thinner and the lower layer becomes thicker, which not only easily leads to the precipitation of particulate matter, but also easily affects the use effect of the pesticide.

[0050] The bottom of the lower medicine barrel 32 is connected to a water pump 321 through a connecting pipe, and a liquid separation box 322 is installed at the output end of the water pump 321. The liquid separation box 322 is connected to multiple spray pipes 323, and a nozzle 324 is installed at one end of the spray pipe 323.

[0051] That is, after the liquid medicine is mixed, the water pump 321 is operated to draw the liquid medicine into the liquid separation box 322, and finally through multiple spray pipes 323, the liquid medicine flows into the nozzle 324, and finally the mixed liquid medicine is sprayed out from the nozzle 324. In this embodiment, after each pesticide spraying is completed, clean water can be added between the upper medicine barrel 31 and the lower medicine barrel 32, and the water pump 321 is operated to achieve the effect of cleaning the upper medicine barrel 31 and the lower medicine barrel 32, the liquid separation box, the spray pipe 323 and the nozzle 324.

[0052] See also Figure 6-Figure 7 The closing mechanism 7 includes a supporting ring 71, a sealing guide strip 72 and a first sealing plug 73.

In this embodiment, the length of the bottom of the support ring 71 is set to relatively extend to the lower medicine barrel 32, and the lengths of the two sealing guide strips 72 are set to be relatively long, so that when the first sealing plug 73 moves up relative to the through hole 4 and detaches from the through hole 4, the sealing guide strip 72 is always in contact with the guide groove 711 at the support ring 71. This setting always makes the guide groove 711 of the support ring 71 contact with the sealing guide strip 72, preventing the support ring 71 from rotating relative to the first sealing plug 73;

After the liquid medicine is mixed, the first sealing plug 73 moves up, so that the liquid medicine enters the lower medicine barrel 32, and then, the first sealing plug 73 moves down to seal the through hole 4, and the subsequent liquid medicine is mixed again. After the subsequent liquid medicine is mixed, the first sealing plug 73 moves up again, so that the upper medicine barrel 31 and the lower medicine barrel 32 maintain a connection through the through hole 4.

[0062] Specific implementation process: after the first pesticide and a certain amount of water are poured into the upper medicine barrel 31, the support shaft 81 drives the rotating rod 83 and the liquid guide tube 5 to rotate through the rotation and grasping operation. When the rotating rod 83 and the liquid guide tube 5 rotate, the multiple synchronous support rods 866 and the two connecting support rods 862 and the guide frame 864 on the outside thereof rotate synchronously. When the first sealing plug 73 rotates synchronously through the two sealing guide strips 72 on the outside thereof, the supporting ring 71 is driven to rotate synchronously, thereby further realizing sufficient stirring of the pesticide and water, and ensuring that the upper medicine barrel 31 and the lower medicine barrel 32 maintain a relatively independent function under the mixed state of the liquid medicine;

[0063] When the stirring is completed, the output end of the electric push rod 852 is retracted, so that the push block 842 drives the push plate 84 to move upward, and when the push plate 84 moves upward, the two connecting rods 862 at the bottom thereof rotate relatively, and when the connecting rods 862 rotate relatively, the movable sleeve 865 is further moved relative to the outer side of the guide frame 864, that is, at this time, the two movable sleeves 865 move in a direction away from each other, and when the movable sleeve 865 moves, the two synchronous rods 866 thereon rotate synchronously, and when the synchronous rods 866 rotate, the first sealing plug 73 is further moved along the outer side of the liquid guide tube 5. The first sealing plug 73 moves upward until the bottom of the first sealing plug 73 is separated from the through hole 4 and maintains a certain distance from the through hole 4, and the mixed medicine liquid enters the lower medicine barrel 32 through the through hole 4. Subsequently, the electric push rod 852 is extended to further move the first sealing plug 73 to the through hole 4 to keep the through hole 4 sealed, so that the remaining pesticides are added, and then a certain amount of water is added for mixing. After the mixing is completed, the first sealing plug 73 moves relatively to the top of the through hole 4, so that the medicine liquid in the upper medicine barrel 31 enters the lower medicine barrel 32, thereby realizing secondary dilution of the medicine liquid, further ensuring that the medicine liquid is fully mixed and preventing the phenomenon of medicine liquid precipitation.

[0064] A liquid guide tube 5 is passed through the through hole 4, and a liquid guide mechanism 6 is provided inside the liquid guide tube 5. The liquid guide tube 5 guides the liquid medicine at the lower medicine barrel 32 to the upper medicine barrel 31 through the liquid guide mechanism 6.

[0072] Specific implementation process: The through hole 4 between the upper medicine barrel 31 and the lower medicine barrel 32 is kept relatively independent by the first sealing plug 73. At this time, the second sealing plug 10 is located between the upper liquid pipe 51 and the lower liquid pipe 53, that is, the second sealing plug 10 keeps the upper medicine pipe and the lower liquid pipe 53 in a relatively independent and sealed state;

[0073] As the push block 842 moves upward, the synchronization rod 643 drives the moving rod 641 to move upward synchronously through the synchronization plate 642. When the moving rod 641 moves upward, the second sealing plug 10 is further separated from the lower liquid pipe 53 and moves continuously along the upper liquid pipe 51. At this time, the liquid outlet shell 521 maintains a state of communication between the lower liquid pipe 53 and the upper medicine barrel 31 through the multiple liquid outlet holes 522 thereon. At this time, after the liquid medicine is diluted for the second time, the rotating motor 633 is operated to The rotating rod 61 drives the spiral blade 62 to rotate. When the spiral blade 62 rotates, the liquid medicine in the upper medicine barrel 31 enters the liquid outlet shell 521 through the lower liquid pipe 53 at the lower medicine barrel 32, and is finally sprayed out from the multiple liquid outlet holes 522 at the rugby-shaped liquid outlet shell 521, further achieving full mixing of the liquid medicine. At the same time, the sprayed liquid medicine flows through the multiple annular shearing knives 523 at the liquid outlet shell 521, and large particles of impurities are crushed and then sprayed out, further ensuring that the liquid medicine is fully mixed.

[0074] During the spraying of the liquid medicine, the upper medicine barrel 31 and the lower medicine barrel 32 remain connected, and the rotating motor 633 runs, thereby ensuring that the liquid medicine is always in a flowing state. Embodiment 2

[0075] See also Figure 3-Figure 4 , Embodiment 2 is a further supplementary description of the rotating member 82 of Embodiment 1, specifically: the rotating member 82 includes a shell 821 fixedly mounted on the top of the upper medicine barrel 31, a driving motor 822 is mounted inside the shell 821, a first rotating gear 823 is fixedly mounted on the output end of the driving motor 822, and a second rotating gear 824 is meshedly connected to the outer side of the first rotating gear 823, and the second rotating gear 824 is fixedly sleeved on the outer side of the support shaft 81, and the shell 821 is used to protect the driving motor 822, the first rotating gear 823 and the second rotating gear 824;

[0076] Thus, by driving the motor 822, the first rotating gear 823 further drives the second rotating gear 824 to rotate. When the second rotating gear 824 rotates, the support shaft 81 further drives the rotating rod 83 at the bottom thereof to rotate. When the rotating rod 83 rotates, the catheter 5 is further rotated.
