[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a seeding machine for UAVs. Background Technology

[0002] With the advancement of technology, agricultural production has gradually evolved from manual labor to the use of machinery. Seeders used for sowing are the main category of agricultural production machinery. However, in recent years, drone seeding has also emerged, which has the advantages of being fast and lightweight compared to traditional seeders.

[0003] Existing drone seeders are prone to clogging when seeding.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a drone-based seeding machine to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a drone-based seeder, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drone-borne seeder includes a connecting plate, an upper shell, a middle shell, and a lower shell. The connecting plate is fixedly connected to the outer wall of the upper shell. The middle shell is fixedly connected to the lower end of the upper shell. A door is provided on the outer wall of the middle shell. The lower shell is fixedly connected to the lower end of the middle shell. A lower support plate is fixedly connected to the inner wall of the lower shell. The lower support plate has multiple evenly distributed lower through slots. A diameter adjustment component is provided at the lower end of each lower through slot to adjust the opening size of the lower through slot. An upper support plate is fixedly connected to the inner wall of the upper shell. A motor is fixedly connected to the upper support plate. The drive end of the motor passes through the upper support plate and is fixedly connected to a rotating shaft. The lower end of the rotating shaft is rotatably connected to the lower support plate. A fixing plate is fixedly sleeved on the outer wall of the rotating shaft. A switching slot is provided on the fixing plate, and the switching slot corresponds one-to-one with the lower through slot. Multiple evenly distributed stirring plates are also fixedly connected to the outer wall of the rotating shaft.

[0008] In a further technical solution, the upper shell, middle shell, and lower shell are integrally formed structures.

[0009] In a further technical solution, the lower through groove of the switching groove has the same size, and the inner wall of the end of the switching groove away from the lower support plate is chamfered.

[0010] In a further technical solution, the stirring plate is provided with multiple evenly distributed openings.

[0011] In a further technical solution, the adjusting assembly includes a threaded shaft, a nut, and a baffle; the bottom end of the lower support plate is fixedly connected to the threaded shaft, the outer wall of the threaded shaft is slidably sleeved with the baffle, and the outer wall of the threaded shaft is also threadedly sleeved with a nut, and the nut abuts against the baffle.

[0012] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0013] 1. Seeds are added into the middle shell through the door. The motor drives the rotating shaft to rotate, which in turn drives the stirring plate to rotate, thereby stirring the seeds and effectively preventing the seeds from clogging the channel. The rotating shaft drives the fixed plate to rotate synchronously, thereby controlling the overlap and offset of the switching slot and the lower through slot. By controlling the rotation of the motor, the overlap time of the switching slot and the lower through slot can be effectively controlled, thereby adjusting the number of seeds passing through the lower through slot and the switching slot at one time, and thus adjusting the sowing rate.

[0014] 2. The opening size of the lower through groove can be adjusted by adjusting the diameter component, so as to accommodate different types of seeds.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-5 As shown in the figure, this utility model embodiment provides a drone-based seeder, including a connecting plate 1, an upper shell 2, a middle shell 3, and a lower shell 4. The connecting plate 1 is fixedly connected to the outer wall of the upper shell 2, and the upper end of the connecting plate 1 is fixedly connected to the drone. The middle shell 3 is fixedly connected to the lower end of the upper shell 2. A door 15 is provided on the outer wall of the middle shell 3. The lower shell 4 is fixedly connected to the lower end of the middle shell 3. A lower support plate 6 is fixedly connected to the inner wall of the lower shell 4. The lower support plate 6 has multiple evenly distributed lower through slots 9, and a diameter adjustment component is provided at the lower end of each lower through slot 9. 13. The diameter adjustment component 13 is used to adjust the opening size of the lower through groove 9. An upper support plate 5 is fixedly connected to the inner wall of the upper housing 2. A motor 14 is fixedly connected to the upper support plate 5. The drive end of the motor 14 passes through the upper support plate 5 and is fixedly connected to a rotating shaft 7. The lower end of the rotating shaft 7 is rotatably connected to the lower support plate 6. A fixing plate 8 is fixedly sleeved on the outer wall of the rotating shaft 7. A switching groove 10 is opened on the fixing plate 8. The switching groove 10 corresponds one-to-one with the lower through groove 9. A plurality of evenly distributed stirring plates 11 are also fixedly connected to the outer wall of the rotating shaft 7. The stirring plates 11 are used to stir seeds.

[0025] Furthermore, the upper shell 2, the middle shell 3, and the lower shell 4 are integrally formed structures.

[0026] Furthermore, the lower through groove 9 of the switching groove 10 has the same size, and the inner wall of the end of the switching groove 10 away from the lower support plate 6 is chamfered.

[0027] Furthermore, the stirring plate 11 is provided with a plurality of evenly distributed openings 12, which reduces the resistance encountered by the stirring plate 11 when stirring seeds.

[0028] like Figure 4 and Figure 5 As shown, the adjusting assembly 13 includes a threaded shaft 131, a nut 132, and a baffle 133; the bottom end of the lower support plate 6 is fixedly connected to the threaded shaft 131, the outer wall of the threaded shaft 131 is slidably sleeved with the baffle 133, the outer wall of the threaded shaft 131 is also threadedly sleeved with the nut 132, and the nut 132 abuts against the baffle 133.

[0029] In practical applications, when it is necessary to adjust the opening size of the lower through groove 9, loosen the nut 132 so that the baffle 133 can rotate. Then rotate the baffle 133 to block part of the lower through groove 9, thereby adjusting the opening size of the lower through groove 9. After that, tighten the nut 132, and the nut 132 will press the baffle 133 upward to fix the baffle 133.

[0030] In this embodiment of the invention, seeds are added into the middle housing 3 through the door 15. The motor 14 drives the rotating shaft 7 to rotate, which in turn drives the stirring plate 11 to rotate, thereby stirring the seeds and effectively preventing them from clogging the channel. The rotating shaft 7 synchronously drives the fixed plate 8 to rotate, thereby controlling the switching groove 10 and the lower through groove 9 to continuously overlap and offset. By controlling the rotation of the motor 14, the overlap time between the switching groove 10 and the lower through groove 9 can be effectively controlled, thereby adjusting the number of seeds passing through the lower through groove 9 and the switching groove 10 at a time, and thus adjusting the sowing amount. The opening size of the lower through groove 9 can be adjusted by the diameter adjustment component 13, thereby accommodating different types of seeds.

[0031] The working principle of this utility model is as follows: the control motor 14 is started, and then the motor 14 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the fixed plate 8 to rotate until the switching groove 10 and the lower through groove 9 are misaligned, thereby blocking the lower through groove 9. Then, seeds are added into the middle shell 3 through the door 15. When it is necessary to sow seeds, the motor 14 continues to control the rotating shaft 7 to rotate. The rotating shaft 7 drives the stirring plate 11 to rotate and stir the seeds. The rotating shaft 7 synchronously drives the fixed plate 8 to rotate, thereby controlling the switching groove 10 and the lower through groove 9 to continuously overlap and misalign. The seeds are sown through the connecting channel between the lower through groove 9 and the switching groove 10.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
