[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] Please see Figures 1 to 5 As shown, a rice sowing device includes a sowing box body 1. The bottom of the sowing box body 1 has a feed inlet 6 connected to a storage tank 7. Several wheels 3 are located at the bottom of the sowing box body 1. A handle 2 is located on one side of the sowing box body 1, used to control the movement of the sowing box body 1 in the field. The sowing box body 1 contains a storage tank 7 for holding rice seeds. Several dispensing mechanisms 16 for controlling the flow of rice seeds are connected below the storage tank 7. Each dispensing mechanism 16 includes several discharge pipes 17 connected to the storage tank 7. A second mounting post 22 is located on one side of each discharge pipe 17. The second mounting post 22 is fixedly installed at the bottom of the sowing box body 1. A third rotating part is rotatably connected to the top of the second mounting post 22. A shaft 21 is connected to a second rotating disk 20 at the top of the third rotating shaft 21. A first rotating disk 18 is set above the second rotating disk 20. A connecting shaft 19 rotatably connects the first rotating disk 18 and the second rotating disk 20. The first rotating disk 18 and the second rotating disk 20 are mirror images of each other. Both the first rotating disk 18 and the second rotating disk 20 have protruding baffles on their outer sides. The two baffles form a space that separates the rice seeds between them, thus achieving the weighting of the rice seeds. The discharge pipe 17 has a groove on its outer side for the first rotating disk 18 and the second rotating disk 20 to enter. The groove does not completely penetrate the discharge pipe 17. The discharge pipe 17 penetrates the seed box body 1. The rice seeds flow out from the discharge pipe 17 and are then sown in the field.

[0028] The seed box body 1 is equipped with a power assembly for providing power to the component mechanism 16. The power assembly includes a second mounting plate 8 fixedly installed on one side inside the seed box body 1. A second motor 11 is fixedly installed at the bottom of the second mounting plate 8. The output end of the second motor 11 is connected to a first rotating shaft 12. One end of a belt 13 is drivenly connected to the outside of the first rotating shaft 12. The other end of the belt 13 is drivenly connected to a second rotating shaft 15. A first mounting post 14 is rotatably connected to the bottom of the second rotating shaft 15. The first mounting post 14 is fixedly installed at the bottom inside the seed box body 1. The belt 13 is also drivenly connected to a third rotating shaft 21. The rotation of the second motor 11 drives the third rotating shaft in the component mechanism 16 to rotate, thereby simultaneously driving the component mechanism 16 inside the seed box body 1 to work.

[0029] A first mounting plate 4 is fixedly installed on one side of the seeding box body 1. A first motor 5 is fixedly installed on the top of the first mounting plate 4. The output end of the first motor 5 passes through the storage tank 7 inside the seeding box body 1 and is connected to a rotating column 9. A propeller blade 10 for sending rice seeds to the discharge pipe 17 is provided on the outside of the rotating column 9. The rotating column 9 drives the propeller blade 10 to rotate, thereby evenly separating the rice seeds and transporting them into the discharge pipe 17.

[0030] The first motor 5 and the second motor 11 are both existing technologies. Their working principles, dimensions, and models are irrelevant to the problems solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0031] Working principle: A batch of rice seeds is put into the storage tank 7 inside the seeding box body 1 through the feed port 6. The first motor 5 on the first mounting plate 4 is started, which drives the rotating column 9 to rotate. In turn, the rotating column 9 drives the propeller blade 10 to rotate inside the storage tank 7, thereby scattering the rice seeds and transporting them to the discharge pipe 17.

[0032] Subsequently, the second motor 11 on the second mounting plate 8 starts, which drives the first rotating shaft 12 to rotate, and then the belt 13 rotates. At the same time, the second rotating shaft 15 at the top of the first mounting column 14 rotates, and then the third rotating shaft 21 on the second mounting column 22 rotates. Simultaneously, the first rotating disk 18 and the second rotating disk 20 rotate. After the protrusions on the first rotating disk 18 and the second rotating disk 20 enter the discharge pipe 17, they will isolate a portion of the seeds. Then they continue to rotate. The baffle on the first rotating disk 18 no longer blocks the rice seeds, so the rice seeds fall from the storage tank 7. At the same time, the baffle on the second rotating disk 20 is still inside the discharge pipe 17, so the rice seeds will not leak out.

[0033] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
