Description

Technical Field

[0001] The utility model is an agricultural UAV based on GPS, belonging to the field of agricultural UAVs. Background Art

[0002] Unmanned aerial vehicles (UAVs), also known as "drones," are unmanned aircraft controlled by radio remote control and self-contained programmable controls, or operated fully or intermittently autonomously by an onboard computer. Compared to manned aircraft, drones are often better suited for tasks deemed "dull, dirty, or dangerous." Drones can be categorized into military and civilian applications. In the military, drones are divided into reconnaissance and target drones. In the civilian sector, drone integration into industrial applications represents a real demand for drones. Current applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television production, and the creation of romance have greatly expanded the uses of drones. Developed countries are also actively expanding industrial applications and developing drone technology.

[0003] When using existing seeding drones, seeds are placed in a seeder on the drone, and the seeds in the seeder are scattered onto the farmland through unmanned flight, thereby completing the drone's seeding task. When the seeder of the existing drone is disassembled to place the seeds, a large number of external tools are needed to complete the disassembly of the seeder, which is inconvenient, slow, time-consuming and labor-intensive, and thus affects the drone's seeding. In addition, the drone cannot be adapted to a variety of unused agricultural equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an agricultural drone based on GPS.

The fixed disk rotates through several inclined extrusion blocks on the circumferential side to squeeze several convex plates at the same horizontal height, thereby pushing the convex plates and the clamping plates to move. The end of the clamping plate is clamped in the clamping groove on the inner wall of the protective shell, thereby stably connecting the protective shell and the mounting column.

[0016] Through the design of the guide column and the guide groove, when the protective shell is sleeved on the outside of the installation column, the guide column and the guide groove can play the role of guidance and quick matching and enable the protective shell to move stably.

The drone body 1 is provided with a combined locator, and a mounting plate 2 is provided at the bottom of the drone body 1. The mounting plate 2 is mounted on the bottom of the drone body 1 by bolts, and the mounting plate 2 is connected to the seeder 18 through a mounting mechanism, and the mounting mechanism comprises a fixed mounting part and a movable mounting part, and the fixed mounting part and the movable mounting part are respectively mounted on the bottom of the mounting plate 2 and the top of the seeder 18, and the movable mounting part comprises a protective shell 15 fixed to the top of the seeder 18, and the protective shell 15 is a topless cylindrical structure, and a plurality of guide columns 16 are evenly arranged on the inner side of the protective shell 15, and a plurality of snap-in grooves 17 are evenly spaced on the inner wall of the protective shell 15 and between the two groups of the guide columns 16.

[0029] See Figure 2-Figure 7The fixing member includes a mounting post 3 fixed to the bottom of the mounting plate 2, and the outer surface of the mounting post 3 is evenly provided with a plurality of guide grooves 4 that cooperate with the guide post 16. The interior of the mounting post 3 is provided with an inner cavity 5, and the circumferential side wall of the inner cavity 5 is evenly provided with a plurality of inlet and outlet holes 9 that penetrate to the outer surface of the mounting post 3. The inner wall of the inlet and outlet holes 9 is evenly spaced with a plurality of groups of slide grooves 10, and a slider 11 is slidably connected in the slide groove 10, and a spring 12 that cooperates with the slider 11 is provided in the slide groove 10. A clamping plate 13 is fixed between the two sliders 11 of the same group, and the clamping plate 13 corresponds to the clamping groove 17. A convex plate 14 is fixed to the end of the clamping plate 13, and the convex plate 14 penetrates into the inner cavity 5. The inner middle part of the inner cavity 5 is rotatably connected with the rotating shaft 6, and the inner top of the inner cavity 5 is fixed with a motor. The bottom output end of the machine is connected to the rotating shaft 6, and the rotating shaft 6 is fixed with several fixed plates 7 corresponding to the convex plates 14 at equal intervals. The circumferential outer surface of the fixed plate 7 is evenly provided with several inclined extrusion blocks 8, and the inclined ends of the inclined extrusion blocks 8 cooperate with the convex plates 14; through the design of the mounting mechanism, when the protective shell 15 on different agricultural equipment is installed with the mounting column 3 at the bottom of the drone body 1, it is only necessary to sleeve the protective shell 15 on the outside of the mounting column 3, and then start the motor rotating shaft 6 and the fixed plate 7 to rotate. The fixed plate 7 rotates through the several inclined extrusion blocks 8 on the circumferential side to squeeze several convex plates 14 at the same horizontal height, thereby pushing the convex plate 14 and the clamping plate 13 to move, and the end of the clamping plate 13 is clamped in the clamping groove 17 on the inner wall of the protective shell 15, thereby stably connecting the protective shell 15 to the mounting column 3.

[0034] When in use, first put an appropriate amount of seeds into the seeder 18, then put the protective shell 15 on the top of the seeder 18 on the outside of the mounting column 3, and insert the several guide columns 16 on the inner wall of the protective shell 15 into the several guide grooves 4 on the outer surface of the mounting column 3, so that the protective shell 15 can move stably. After the protective shell 15 is inserted into the outside of the mounting column 3, the motor is started by the controller, and the motor drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the several fixed disks 7 to rotate, and the fixed disk 7 rotates through the several inclined extrusion blocks 8 on the circumferential side to squeeze Several convex plates 14 at the same horizontal height push the convex plate 14 into the inlet and outlet hole 9.
