[0035] like Figure 1-Figure 5 As shown, the utility model provides a seed drill, which is mounted on a tractor or other traction equipment for traction and movement. The seed drill includes a frame 1, and also includes a seeding assembly, a pressing assembly, and a soil covering and pressing roller 2 installed on the frame 1. The seeding assembly includes a seed box 3, a seed separator 4 rotatably installed on the frame 1 through a bearing, and a seed meter 5 arranged opposite to the seed separator 4. A plurality of seed boxes 3 are arranged along the axial direction of the seed separator 4, and the seed box 3 is openly arranged on one side facing the seed separator 4, and the seed separator 4 is arranged opposite to the seed box 3.

[0036] The seed box 3 is mounted on the shaking assembly, and the shaking assembly is fixedly mounted on the frame 1. Specifically, the shaking assembly includes a shaking motor 12 and a shaking rod 13 mounted on the shaking motor 12. The bottom of the seed box 3 is fixedly mounted on the shaking rod 13, and the shaking motor 12 is fixedly mounted on the frame 1. The shaking motor 12 drives the seed box 3 to shake through the shaking rod 13, so that the seeds in the seed box 3 shake, so that the seeds enter the separation hole 6 on the seed separator 4.

[0037] The seed separator 4 is cylindrical, and a plurality of separation holes 6 are evenly distributed on the outer wall of the seed separator 4 and spaced apart along the axial direction of the seed separator 4. The aperture of the separation hole 6 is adapted to the diameter of the seeds to be sown, so that one separation hole 6 can only be filled with one red bean seed or mung bean seed at a time.

[0038] The number of seeding devices 5 is equal to the number of circles of separation holes 6. The seeding devices 5 are spaced apart along the axial direction of the seed separator 4. The seeding devices 5 include a seeding tube 7 and an inoculation port 8 arranged on the top of the seeding tube 7. The inoculation port 8 is arranged opposite to the corresponding separation holes 6. The bottom of the seeding tube 7 is open for seeds to fall.

[0039] The pressing assembly includes a roller shaft 9 and pressing columns 10 evenly distributed on the roller shaft 9. The pressing columns 10 are evenly distributed in multiple circles along the axial direction of the roller shaft 9. The seed meter 5 is arranged opposite to the pressing columns 10. The pressing columns 10 are used to press the seeds that fall on the ground into the soil so that the seeds can better contact with the soil.

[0040] The seed separator 4 is driven by a driving motor 11. In order to facilitate the control of the rotation speed of the driving motor 11, in this embodiment, the driving motor 11 adopts a servo motor. The seed separator 4 is connected to the roller shaft 9 through a transmission assembly, and the rotation direction of the seed separator 4 is opposite to that of the roller shaft 9.

[0041] Specifically, the transmission assembly includes a first gear 15 and a second gear 16 that are meshed with each other. The first gear 15 and the second gear 16 are rotatably mounted on the frame 1 via a first rotating shaft 17 and a second rotating shaft 18, respectively. Sprockets 19 are mounted on the first rotating shaft 17 and the second rotating shaft 18. The sprocket 19 of the first rotating shaft 17 is connected to the seed separator 4 via a chain, and the sprocket 19 on the second rotating shaft 18 is connected to the roller shaft 9 via a chain.

[0042] In order to allow all the seeds in the seed box 3 to be filled by the seed separator 4, the bottom of the seed box 3 is tilted toward the side of the seed metering device 5. The inoculation port 8 is open toward one side of the seed separator 4 to facilitate receiving the seeds falling out of the separation hole 6.

[0043] In summary, after the seeder provided by the utility model is mounted on the traction equipment, it is towed and moved by the traction equipment, does not require manual pushing, has a high degree of automation, and has the functions of seed pressing and soil covering and pressing, which greatly saves the labor cost of mung bean sowing.

[0044] Finally, it should be noted that the various technical features of the technical solution of the present application can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of the present application.
