[0003] Chinese Patent Announcement No. CN221510209U discloses an agricultural seeding machine. This machine includes a seed storage box, a seed distribution pipe, and tillage wheels. A bottom mounting bracket is fixedly connected to the bottom of the seed storage box. Rollers are rotatably connected to both sides of the bottom mounting bracket. Tillage wheels are evenly rotatably connected to the front and rear sides of the bottom mounting bracket in a horizontal direction. Fixed pipes are fixedly connected to the front and rear side walls of the seed storage box. This invention stores seeds for sowing using the seed storage box.

[0029] Example:
[0030] Please see Figure 1 , Figure 2 and Figure 3 An agricultural seeding machine includes a base 1, a conveying cylinder 2 fixedly connected to the top center of the base 1, a feeding bin 3 fixedly connected to the top of the conveying cylinder 2, a feeding port 4 opened on the top wall of the feeding bin 3, a grid plate 5 fixedly connected to the middle of the inner wall of the conveying cylinder 2, a fixed plate 6 fixedly connected to the lower middle part of the inner wall of the conveying cylinder 2, a plurality of first discharge ports 7 equidistantly opened on the outer wall of the fixed plate 6, a plurality of second discharge ports 8 equidistantly opened on the outer wall of the fixed plate 6 near the first discharge ports 7, a limiting plate 9 provided on the inner wall of the conveying cylinder 2, a plurality of limiting blocks 10 fixedly connected to the inner wall of the limiting plate 9 equidistantly, a first connecting column 11 fixedly connected to the top of the limiting plate 9, the first connecting column 11 being rotatably connected to the bottom wall of the fixed plate 6, a driving assembly provided at the bottom of the limiting plate 9; and a storage bin 21 fixedly connected to the rear end of the top wall of the base 1.
[0031] This solution involves scattering the seeds into the feed inlet 4. After the seeds enter the conveying cylinder 2, the falling speed of the seeds can be controlled by the grid plate 5 to prevent them from falling too quickly and causing blockage at the discharge point, which would affect sowing. The outer wall of the fixed plate 6 is divided into eighteen equal parts, and the first discharge port 7 and the second discharge port 8 are opened in twelve of them respectively, which work in conjunction with the drive component. The seeds can be stored in the storage bin 21 set at the bottom rear end of the base 1 to meet the needs of long-term sowing.
[0032] Please see Figure 2 and Figure 3 The drive assembly includes a motor 12, which is mounted on the bottom of the base 1. A connecting rod 13 is fixedly connected to the output end of the motor 12. A first bevel gear 14 is fixedly connected to the end of the connecting rod 13. A second bevel gear 15 is meshed with the outer wall of the first bevel gear 14. A second connecting post 16 is fixedly connected to the top of the second bevel gear 15. The top of the second connecting post 16 is fixedly connected to the bottom wall of the limiting plate 9. Two limiting balls 22 are provided in the upper part of the inner wall of the feeding cylinder 2. Multiple fixing rods 23 are fixedly connected at equal intervals to the outer wall of the limiting balls 22. The ends of the fixing rods 23 are fixedly connected to the inner wall of the feed inlet 4.
[0033] This solution controls the rotation of the first bevel gear 14 by starting the motor 12, which in turn drives the second bevel gear 15 to rotate synchronously. The second bevel gear 15, in conjunction with the second connecting column 16, can control the synchronous rotation of the limiting disk 9. Six limiting blocks 10 are fixedly connected at equal intervals on the inner wall of the limiting disk 9. By controlling the overlapping position of the limiting disk 9 and the fixed disk 6, the discharge rate can be controlled to meet different sowing needs. The design of the limiting ball 22 and the fixing rod 23 can be used in conjunction with the grid disk 5 to control the speed at which the seeds fall.
[0034] Please see Figure 1 and Figure 4 The base 1 has casters 19 installed on the front, rear and left sides of the bottom; the base 1 has connecting plates 17 fixedly connected to the left and right sides of the rear of the bottom wall; the two connecting plates 17 are rotatably connected to the adjacent sides of the two connecting plates 17; the base 1 has a control console 20 installed on the front of the top wall.
[0035] This solution uses the control console 20 to drive the base 1 to move the control device with the bottom moving wheels 19, thereby achieving the effect of automatic movement and sowing; the soil turning wheel 18 is installed at the bottom rear end of the base 1 through the connecting plate 17, so that the soil can be turned and backfilled by the soil turning wheel 18 when the device moves, ensuring the sowing effect.
[0036] Working principle: When sowing is required, seeds are conveyed from the feed inlet 4 at the top of the feed hopper 3 into the conveying cylinder 2. After entering the conveying cylinder 2, the seeds fall onto the limiting ball 22. At the same time, the grid plate 5 can control the speed of seed falling to avoid accumulation and affect the discharge efficiency. The outer wall of the fixed plate 6 has six first discharge ports 7 and second discharge ports 8 equidistantly opened, while six empty positions are left unopened, which is equivalent to dividing the outer wall of the fixed plate 6 into eighteen equal parts. The width of the limiting block 10 is about one-eighteenth of the fixed plate 6. The starting motor 12 controls the first bevel gear 14 and the second bevel gear 15 to mesh and connect, thereby controlling the limiting plate 9 to rotate synchronously. Personnel can control the rotation angle of the limiting plate 9 according to different sowing needs. The overlapping position of the limiting plate 9 and the fixed plate 6 can have three different discharge space sizes: discharge from the first discharge port 7, discharge from the second discharge port 8, and discharge from both discharge ports. The above design can meet different sowing needs and improve the practicality of the device.
[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
