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

[0025] Specific examples are given below.

[0026] See also Figure 1-Figure 3The utility model provides a drone medicine spraying device for rice planting, comprising a drone body 1; a storage box 11 is fixedly connected to the side wall of the drone body 1; a pair of spraying mechanisms 12 are hingedly connected to the side wall of the storage box 11; the spraying mechanisms 12 are symmetrically arranged on both sides of the storage box 11 and have the same structure; a conveying pipe 13 is fixedly connected between the spraying mechanism 12 and the storage box 11; a servo motor 14 is fixedly connected to the side wall of the storage box 11; a screw rod 15 is fixedly connected to the output end of the servo motor 14; a connecting block 16 is threadedly connected to the side wall of the screw 15; a pull rope 17 is fixedly connected between the connecting block 16 and the spraying mechanism 12; when in use, the drone body 1 is controlled by a staff member, and the medicine in the storage box 11 is transported into the spraying mechanism 12 through the conveying pipe 13, and sprayed to the outside through the spraying mechanism 12, and the servo motor 14 is started at the same time during the spraying process. The servo motor 14 can drive the screw 15 to rotate through the servo motor 14, and as the screw 15 rotates, the connecting block 16 can be lifted and lowered. At this time, the pull rope 17 can be pulled by moving the connecting block 16, so that the spraying mechanisms 12 on both sides can be pulled to an inclined state. After that, when the connecting block 16 moves to a certain extent, the screw 15 is reversed by the servo motor 14, so that the connecting block 16 rises, and the pull rope 17 pulls the spraying mechanism 12 to reset. At this time, the spraying mechanism 12 can be swung and sprayed by repeatedly lifting and lowering the connecting block 16 to increase the spraying range. In this process, the spraying angle of the drone can be reduced to a fixed setting, resulting in a smaller spraying range and difficulty in evenly spraying the medicine. At this time, the spraying mechanism 12 is repeatedly swung by pulling the pull rope 17, thereby increasing the spraying range of the spraying mechanism 12 and improving the uniformity of the drug spraying.

[0027] Further, such as Figure 2-Figure 5As shown, the output end of the servo motor 14 is fixedly connected with a protrusion 2; the side wall of the storage box 11 is fixedly connected with a liquid storage tube 21; the inner side wall of the liquid storage tube 21 is slidably connected with a ball 22; when in use, a staff member first injects a certain amount of lubricating oil into the liquid storage tube 21, and then as the output end of the servo motor 14 rotates, when the protrusion 2 rotates to correspond to the position of the ball 22, the protrusion 2 will squeeze the ball 22, and the ball 22 can be squeezed into the liquid storage tube 21 by squeezing. At this time, the lubricating oil in the liquid storage tube 21 will flow out through the gap between the ball 22 and the liquid storage tube 21, and finally flow to the side wall of the screw 15, so that it enters the connecting block 1 6 and the screw 15, and lubricates them. When the protrusion 2 turns away from the ball 22, the ball 22 will automatically reset under the action of gravity, so that it is blocked on the inner wall of the liquid storage tube 21 to prevent the lubricating oil from flowing out. In this process, the rust of the screw 15 during long-term use can be reduced, which will cause a certain impact on the smoothness of rotation between the screw 15 and the connecting block 16, thereby affecting the rotation effect of the connecting block 16. At this time, the lubricating oil in the liquid storage tube 21 flows to the side wall of the screw 15, thereby playing a lubricating role during the rotation between the screw 15 and the connecting block 16, and improving the smoothness of rotation between the screw 15 and the connecting block 16.

[0028] Further, such as Figure 3-Figure 5 As shown, the side wall of the liquid storage tube 21 is hinged with a filter screen plate 3; the side wall of the filter screen plate 3 is fixedly connected with an insert block 31; the side wall of the liquid storage tube 21 is fixedly connected with a mounting block 32; the side wall of the mounting block 32 is hinged with a clamping block 33; the side wall of the inserting block 31 is provided with a clamping slot 34; when in use, firstly inject a certain amount of lubricating oil into the liquid storage tube 21, then hold and pull the clamping block 33, and then hold the filter screen plate 3 to cover it above the liquid storage tube 21, so that the inserting block 31 is inserted into the slot of the mounting block 32, at which time the clamping block 33 will correspond to the position of the clamping slot 34, and by loosening the clamping block 33, it will automatically reset under the action of the internal torsion spring at its hinge. It is stuck into the side wall of the card slot 34, so that the filter screen plate 3 can be fixed. At this time, during the flight of the drone body 1, the filter screen plate 3 can block external dust and impurities, so that they will not enter the liquid storage tube 21, and the staff can observe the remaining lubricating oil in the liquid storage tube 21 through the filter screen plate 3. In this process, the liquid storage tube 21 can be less exposed to the outside world for a long time, which makes it easy for external dust and impurities to enter the liquid storage tube 21 and mix with the lubricating oil, affecting the normal use effect of the lubricating oil. At this time, the dust and impurities are filtered through the filter screen plate 3, thereby playing a dust-proof role when the liquid storage tube 21 is in use.

[0029] Further, such as Figure 4 , Figure 5As shown, the side wall of the filter screen plate 3 is rotatably connected to the rotating rod 4; the side wall of the rotating rod 4 is fixedly connected to a pair of cleaning brush plates 41; the cleaning brush plates 41 are symmetrically arranged on both sides of the rotating rod 4 and have the same structure; the side wall of the cleaning brush plate 41 is fixedly connected to a connecting rod 42; when in use, the staff holds and rotates the rotating rod 4, and at this time, the side wall of the filter screen plate 3 can be cleaned by the cleaning brush plate 41, and the dust and impurities attached to the side wall of the filter screen plate 3 can be swept away, and at the same time, during the cleaning process of the cleaning brush plate 41, the cleaning brush can be The bristles on the side wall of the plate 41 are fixedly connected so that they are gathered together during the cleaning process. In this process, the filter screen plate 3 can be reduced during long-term use, resulting in a lot of dust and impurities attached to the side wall of the filter screen plate 3, which is inconvenient to clean, thereby affecting the observation effect of the residue in the liquid storage tube 21. At this time, the side wall of the filter screen plate 3 is cleaned by the cleaning brush plate 41, thereby cleaning the dust and impurities attached to the side wall of the filter screen plate 3, and the cleaning effect of the cleaning brush plate 41 can be improved by the connecting rod 42.

[0030] Further, such as Figure 4 , Figure 5 As shown, a pair of elastic rods 5 are fixedly connected to the side wall of the filter screen plate 3; the elastic rods 5 are symmetrically arranged on both sides of the filter screen plate 3 and have the same structure; a counterweight ball 51 is fixedly connected to the end of the elastic rod 5; an elastic sheet 52 is fixedly connected to the side wall of the cleaning brush plate 41; when in use, when the staff holds the rotating rod 4 and rotates it to rotate the elastic sheet 52 to the position of the counterweight ball 51, the elastic sheet 52 will hit the wall of the counterweight ball 51, and the impact force generated by the collision can cause a certain deformation of the elastic sheet 52 and the elastic rod 5. When the two are staggered, the elastic sheet 52 and the elastic rod 5 are deformed. Under the elastic action of the sheet 52, it will automatically reset and shake. The vibration generated by the shaking can shake off the dust and impurities attached to the side wall of the cleaning brush plate 41. In this process, the cleaning brush plate 41 can be reduced during long-term use, which makes it easy for more dust and impurities to adhere to the side wall of the cleaning brush plate 41, making it inconvenient to clean them, thereby causing a certain impact on the cleaning effect of the cleaning brush plate 41. At this time, the vibration generated by the shaking of the elastic sheet 52 can clean the dust and impurities attached to the side wall of the cleaning brush plate 41.

[0031] Further, such as Figure 5 As shown, the side wall of the card block 33 is fixedly connected with a buckle plate 6; the buckle plate 6 is arranged in an arc shape; when in use, the staff puts the finger on the side wall of the buckle plate 6 and pulls it. At this time, the finger can be hooked under the arc action of the buckle plate 6, and then the card block 33 can be pulled open. In this process, the staff can reduce the inconvenience of holding the card block 33 when pulling it open, which makes it easy for the staff to slip off the side wall when pulling it. At this time, the buckle plate 6 is set, which makes it convenient to pull the card block 33 open.

[0032] Further, such as Figure 5 As shown, the side wall of the buckle plate 6 is evenly fixed with multiple anti-skid pads 7; when in use, when the staff places their fingers on the side wall of the buckle plate 6 and pulls, a certain friction force will be generated through the contact between the fingers and the anti-skid pads 7. In this process, the friction force between the fingers and the buckle plate 6 can be reduced, causing easy sliding when pulling. At this time, the anti-skid pads 7 are set to increase the firmness of the fingers on the side wall of the buckle plate 6.

[0033] Working principle: When in use, the staff controls the drone body 1, and the medicine in the storage box 11 is transported into the spraying mechanism 12 through the delivery pipe 13, and sprayed to the outside through the spraying mechanism 12. During the spraying process, the servo motor 14 is started at the same time, and the servo motor 14 can drive the screw 15 to rotate. As the screw 15 rotates, the connecting block 16 can be lifted and lowered. At this time, the pull rope 17 can be pulled by the movement of the connecting block 16, so that the spraying mechanisms 12 on both sides can be pulled to an inclined state. After that, when the connecting block 16 moves to a certain extent, the servo motor 14 drives the screw 15 to reverse, so that the connecting block 16 rises, and the pull rope 17 pulls the spraying mechanism 12 to reset. At this time, the connecting block 1 6 repeatedly lifts and lowers, so that the spraying mechanism 12 can swing and spray to increase the spraying range. When in use, the staff first injects a certain amount of lubricating oil into the liquid storage tube 21. Then, as the output end of the servo motor 14 rotates, when the protrusion 2 rotates to correspond to the position of the ball 22, the protrusion 2 will squeeze the ball 22, and the ball 22 can be squeezed into the liquid storage tube 21 by squeezing. At this time, the lubricating oil in the liquid storage tube 21 will flow out through the gap between the ball 22 and the liquid storage tube 21, and finally flow to the side wall of the screw 15, so that it enters between the connecting block 16 and the screw 15 to lubricate it. When the protrusion 2 turns away from the ball 22, under the action of gravity, the ball 22 will automatically reset and block the inner wall of the liquid storage tube 21. , to prevent the lubricating oil from flowing out. When in use, first inject a certain amount of lubricating oil into the liquid storage tube 21, hold and pull the clamping block 33, and then hold the filter screen plate 3 to cover it above the liquid storage tube 21, so that the insertion block 31 is inserted into the groove of the mounting block 32. At this time, the clamping block 33 will correspond to the position of the clamping slot 34. By loosening the clamping block 33, it will automatically reset under the action of the internal torsion spring at its hinge, so that it is clamped into the side wall of the clamping slot 34, thereby fixing the filter screen plate 3. At this time, during the flight of the drone body 1, the filter screen plate 3 can block external dust and impurities from entering the liquid storage tube 21, and the staff can observe the remaining lubricating oil in the liquid storage tube 21 through the filter screen plate 3. When the cleaning brush plate 41 is used, the bristles on the side wall of the cleaning brush plate 41 can be fixedly connected through the connecting rod 42 so that the bristles on the side wall of the cleaning brush plate 41 can be gathered together during the cleaning process. When in use, when the staff holds the rotating rod 4 and rotates it, the elastic sheet 52 rotates to the position of the counterweight ball 51, and the elastic sheet 52 hits the wall of the counterweight ball 51. The impact force generated by the collision can cause the elastic sheet 52 and the elastic rod 5 to produce a certain deformation. When the two are staggered, they will automatically reset and shake under the elastic action of the elastic sheet 52.The vibration generated by shaking can shake off the dust and impurities attached to the side wall of the cleaning brush plate 41. When in use, the staff puts their fingers on the side wall of the pinch plate 6 and pulls it. At this time, the pinch plate 6 can hook the fingers under the arc action, and then the block 33 can be pulled open. When in use, when the staff puts their fingers on the side wall of the pinch plate 6 and pulls it, a certain friction force will be generated by the contact between the fingers and the anti-slip pad 7.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
