Description

Technical Field

[0001] This utility model relates to the field of rice sprayer technology, and in particular to a novel rice sprayer. Background Technology

[0002] Rice is one of the world's most important food crops, and it is grown all over the world. When rice is being grown, pesticides need to be sprayed evenly in the rice fields using sprayers. These sprayers are usually drones equipped with spraying devices to carry out the pesticide spraying work.

[0003] However, in the existing technology, when fixing drones and pesticide sprayers, they are usually connected and installed by bolts and other fixing parts. The installation and disassembly not only require disassembly tools, but the disassembly process is also quite complicated, making the device inconvenient to use. The preliminary preparation work and subsequent disassembly work are cumbersome and take a long time, making it impossible to achieve rapid disassembly and assembly operations. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of rice sprayer, which aims to improve the problem that when fixing drones and pesticide sprayers, they are usually connected and installed by fixing parts such as bolts. The installation and disassembly not only require disassembly tools, but the disassembly and cleaning process is also relatively complicated, making the device inconvenient to use. This results in cumbersome preparation and disassembly work that takes a long time and cannot achieve quick assembly and disassembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a drone body and a liquid storage tank.

[0010] As a further description of the above technical solution: the transmission belt can be used to connect two synchronous pulleys so that they can rotate simultaneously.

[0011] Preferably, a first movable rod is fixedly connected to the lower end of the rotating rod, and a second movable rod is rotatably connected to one end of the first movable rod.

[0012] As a further description of the above technical solution: after the first movable rod is moved, the second fixed plate fixed to its end can also be moved.

[0013] Preferably, a gear is fixedly connected to the upper end of the second movable rod, and a toothed ring is fixedly connected to the upper part of the inside of the liquid storage tank.

[0014] As a further description of the above technical solution: the gear can move on the toothed ring when the second movable rod moves, and thus rotate.

[0015] Preferably, the outer surface of the gear meshes with the inner surface of the toothed ring, and a stirring rod is fixedly connected to both sides of the lower end of the second movable rod.

[0016] As a further description of the above technical solution: the stirring rod can stir the pesticide in the storage tank after rotation, so as to avoid precipitation.

[0017] Preferably, a liquid inlet pipe is fixedly connected to one side of the liquid storage tank, and a spraying mechanism is fixedly connected to the lower end of the liquid storage tank.

[0018] As a further description of the above technical solution: the inlet pipe can be used to inject pesticide liquid into the storage tank.

[0019] Preferably, support rods are fixedly connected to both sides of the lower end of the liquid storage tank, and reinforcing ribs are fixedly connected to the upper ends of the four buckle rods.

[0020] As a further description of the above technical solution: the support rod is a support component at the bottom of the liquid storage tank.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, when connecting and fixing the liquid storage tank and the main body of the drone, the installation of the device can be completed simply by turning the knob to control the buckle frame and the buckle rod to engage.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 3As shown, one embodiment of this utility model includes a drone body 1 and a liquid storage tank 7. The liquid storage tank 7 is located at the lower end of the drone body 1. All four sides of the lower end of the drone body 1 are fixedly connected with latching rods 2. The upper end of the liquid storage tank 7 is slidably connected to two sides of the upper end of the liquid storage tank 7. The upper end of the liquid storage tank 7 is rotatably connected with a bidirectional screw 10. The outer surface of the bidirectional screw 10 is threadedly connected to the middle of the two latching frames 9 respectively. One end of the bidirectional screw 10 is fixedly connected to a knob 13. One end of the four latching rods 2 is respectively engaged with the two ends of the two latching frames 9.

[0032] In this embodiment, when connecting the drone body 1 and the liquid storage tank 7, the drone body 1 can be placed above the liquid storage tank 7, and then the knob 13 can be turned to drive the bidirectional lead screw 10 to rotate. At this time, the rotating bidirectional lead screw 10 can drive the two side buckle frames 9 to separate from each other, so that the two sides of the buckle frames 9 are respectively engaged with the ends of the buckle rods 2 at the lower end of the drone body 1. At this time, the drone body 1 and the liquid storage tank 7 can be connected and fixed together. When disassembling later, the above steps can be repeated in reverse to complete the operation. With this method, when connecting and fixing the liquid storage tank 7 and the drone body 1, the buckle frames 9 and buckle rods 2 can be engaged by turning the knob 13 to complete the installation of the device. It is more convenient and faster in subsequent use or disassembly and assembly, and the time for the initial preparation and subsequent disassembly of the device is greatly shortened.

[0033] Example 2, as Figures 1 to 5 As shown, a motor 4 is fixedly connected to one side of the liquid storage tank 7, a rotating rod 3 is rotatably connected to the upper end of the liquid storage tank 7, a synchronous pulley 11 is fixedly connected to the upper end of the rotating rod 3 and the output end of the motor 4, a transmission belt 12 is connected between the two synchronous pulleys 11, a first movable rod 14 is fixedly connected to the lower end of the rotating rod 3, a second movable rod 17 is rotatably connected to one end of the first movable rod 14, a gear 15 is fixedly connected to the upper end of the second movable rod 17, a toothed ring 16 is fixedly connected to the upper part of the inside of the liquid storage tank 7, the outer surface of the gear 15 meshes with the inner surface of the toothed ring 16, a stirring rod 18 is fixedly connected to both sides of the lower end of the second movable rod 17, an inlet pipe 8 is fixedly connected to one side of the liquid storage tank 7, a spray mechanism 5 is fixedly connected to the lower end of the liquid storage tank 7, a support rod 6 is fixedly connected to both sides of the lower end of the liquid storage tank 7, and a reinforcing rib 19 is fixedly connected to the upper end of the four latching rods 2.

[0034] In this embodiment, the pesticide solution is injected into the storage tank 7 through the inlet pipe 8. During its temporary storage, the pesticide is prone to precipitate inside the storage tank 7. At this time, the motor 4 can be started to drive one of the synchronous pulleys 11 to rotate, which in turn drives the other synchronous pulley 11 to rotate under the action of the transmission belt 12. The rotating rod 3, which is fixedly connected to the other synchronous pulley 11, can rotate accordingly and drive the first movable rod 14 to move inside the storage tank 7, thereby driving the second movable rod 17 at its end to move. The movable second movable rod 17 will rotate on its own axis while revolving under the action of the gear 15 and the toothed ring 16, thereby driving the fixed stirring rod 18 below to stir, so that the pesticide solution inside the storage tank 7 can be fully stirred and the precipitation situation can be avoided.

[0035] Working principle: When using the device, pesticide solution is injected into the storage tank 7, and the drone body 1 drives the storage tank 7 to fly, spraying the pesticide through the spraying mechanism 5. To connect the drone body 1 to the storage tank 7, the drone body 1 is placed above the storage tank 7, and then the knob 13 is turned to rotate the bidirectional lead screw 10. The rotating bidirectional lead screw 10 drives the two side locking brackets 9 to separate, allowing both sides of the locking brackets 9 to engage with the ends of the locking rods 2 at the lower end of the drone body 1. This connects and fixes the drone body 1 to the storage tank 7. Disassembly is then performed by simply repeating the above steps. This method allows for easy connection and fixation of the storage tank 7 and the drone body 1 by simply rotating the knob 13 to engage the locking brackets 9 and locking rods 2, thus completing the installation. The subsequent use or disassembly process is more convenient and quick, greatly shortening the time of the initial preparation work and the subsequent disassembly work of the device. The pesticide liquid is injected into the storage tank 7 through the liquid inlet pipe 8. During its temporary storage, the pesticide is prone to precipitation inside the storage tank 7. At this time, the motor 4 can be started to drive one of the synchronous pulleys 11 to rotate, and then the transmission belt 12 drives the other synchronous pulley 11 to rotate. At this time, the rotating rod 3, which is fixedly connected to the other synchronous pulley 11, can rotate accordingly, and drive the first movable rod 14 to move inside the storage tank 7, and then drive the second movable rod 17 at its end to move. The moving second movable rod 17 will rotate on its own axis while revolving under the action of the gear 15 and the toothed ring 16, thereby driving the fixed stirring rod 18 below to stir, so that the pesticide liquid inside the storage tank 7 can be fully stirred and the precipitation situation can be avoided.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
