Multiple identical round tubes 4 are connected between the multiple feed inlets and discharge outlets. The multiple discharge outlets are internally threaded with duckbill seed dispensing ports 5. A round sleeve 3 is fixedly connected to the bracket 1. The round sleeve 3 is rotatably fitted onto the seeding tray 2. A feed pipe is sealed to the round sleeve 3, and the feed pipe corresponds to multiple feed inlets. A sleeve 6 is fixedly connected to one side of the round sleeve 3. A threaded rod 7 is fixedly connected to one end of the fixed rod. Through the cooperative design between the bracket 1, seeding tray 2, round sleeve 3, duckbill seed dispensing port 5, threaded rod 7, separating wheel 8, adjusting handle 11, and bolt 10, not only can corn seeds be sown in holes, but the spacing of the corn seeds can also be adjusted appropriately according to the user's needs. Furthermore, the handle can be adjusted appropriately according to the user's needs, greatly improving convenience and flexibility.

[0030] In this embodiment, one end of the threaded rod 7 passes through the round sleeve 3 and the sleeve 6. A separating wheel 8 is slidably mounted on the threaded rod 7. The separating wheel 8 rotates inside the sleeve 6. Through the cooperation between the sleeve 6, the threaded rod 7, and the separating wheel 8, the effect of intermittently and quantitatively feeding corn seeds can be achieved. The corn seeds can be intermittently transported to the discharge pipe at the bottom of the sleeve 6 by the action of the separating wheel 8. The specific structure and working material of the separating wheel 8 can be referred to the literature with application number: 201620213458.X. This is prior art and will not be described in detail.

[0031] In this embodiment, one end of the threaded rod 7 is threadedly connected to a limiting block, which is in contact with one side of the separating wheel 8. The separating wheel 8 is adapted to the sleeve 6 and is used to block and limit the separating wheel 8. A groove is provided on the separating wheel 8, and a protrusion is fixedly connected to the threaded rod 7. The protrusion is connected to the groove for transmission.

[0032] In this embodiment, a discharge pipe is sealed to the bottom of the sleeve 6. One end of the discharge pipe is sealed to the feed pipe. The discharge pipe corresponds to the separating wheel 8 and is used to transport corn seeds into the seeding tray 2.

[0033] In this embodiment, a storage bucket 12 is fixedly installed on the support 1 for storing a certain amount of corn seeds. A corrugated pipe is sealed to the bottom of the storage bucket 12. One end of the corrugated pipe is sealed to the sleeve 6 and corresponds to the separating wheel 8 for conveying corn seeds into the sleeve 6. A collection box for storing multiple sealing plugs 13 is installed on the support 1.

[0034] In this embodiment, one end of the bracket 1 is threadedly connected to an adjustment handle 11. The bracket 1 has a groove 9. One end of the adjustment handle 11 is threadedly connected to a bolt 10. One end of the bolt 10 passes through the adjustment handle 11 and engages with the groove 9. The user can rotate the adjustment handle 11 to make it threadedly drive the bracket 1, thereby achieving the effect of adjusting the length of the handle appropriately. The bolt 10 is aligned with the groove 9. Then, by rotating the bolt 10 and extending one end into the groove 9, the handle can be adjusted appropriately according to the user's needs.

[0035] In this embodiment, a sealing plug 13 is installed in each of the multiple feed inlets. One side of each sealing plug 13 is flush with one side of the seeding tray 2, which is used to seal the unused feed inlets on the seeding tray 2.

[0036] In this embodiment, each of the multiple duckbill seeding ports 5 is sealed with a connecting pipe on one side. One end of each connecting pipe is threadedly connected to a multiple discharge port, facilitating the assembly and disassembly of the multiple duckbill seeding ports 5. Each connecting pipe is threaded with a reinforcing nut for reinforcement. The seeding disc 2 rolls forward, the duckbill-shaped seeding shell inserts into the soil to make holes, and continues to roll. The spring pressure plate on the right side of the duckbill-shaped seeding shell contacts the ground and is pressed, causing the movable door to open. At the same time, the switch spring is compressed, and the corn seeds are sown into the holes from the opened duckbill-shaped seeding shell. The roller continues to roll forward, the spring pressure plate leaves the ground, and the movable door closes under the action of the switch spring, completing the seeding process. The specific structure and working materials of the duckbill seeding port 5 can be referred to the literature with application number 202020056448.6, which is prior art and will not be described in detail here.

[0037] Working principle: When in use, first prepare multiple separating wheels 8, and then place the separating wheels 8 corresponding to the multiple duckbill seed outlets 5 installed on the seeding tray 2 inside the sleeve 6;

[0038] By adjusting the coordination between the handle 11, the bracket 1, and the seeding tray 2, multiple duckbill seed outlets 5 roll on the ground. At the same time, the seeding tray drives the fixing rod to rotate on the bracket 1. Simultaneously, the fixing rod drives the separating wheel 8 to rotate inside the sleeve 6 through the transmission of the threaded rod 7. At this time, the corn seeds can be intermittently transported to the discharge pipe at the bottom of the sleeve 6 through the action of the separating wheel 8. The corn seeds are then transported to the corresponding duckbill seed outlets 5 through the action of the feed pipe on the round sleeve 3, the corresponding feed hole, the round pipe 4, and the discharge port. After that, the corn seeds are precisely sown in holes through the action of the duckbill seed outlets 5.

[0039] When it is necessary to adjust the spacing of corn seed planting holes, firstly, loosen the reinforcing nut on the connecting pipe by rotating it, and then disassemble the duckbill seed outlet 5 by rotating it so that the connecting pipe is detached from the seeding tray 2. Conversely, it can be installed. By adjusting the position of multiple duckbill seed outlets 5 on the seeding tray 2, the spacing of corn seed planting holes can be adjusted. At the same time, replace the matching separating wheel 8, and seal the unused feed port on the seeding tray 2 with the sealing plug 13.

[0040] The user can rotate the adjustment handle 11 to make it threaded with the bracket 1, thereby achieving the effect of adjusting the length of the handle appropriately. The bolt 10 is aligned with the groove 9. Then, by rotating the bolt 10 and extending one end into the groove 9, the interaction between the bolt 10 and the groove 9 achieves the effect of limiting and fixing the adjustment handle 11, thereby enabling the user to adjust the handle appropriately according to their needs.

[0041] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, it not only enables the sowing of corn seeds in holes, but also allows for the appropriate adjustment of the spacing between corn seed holes according to user needs. Furthermore, the handle can be adjusted according to user requirements, greatly improving convenience and flexibility. Moreover, the structure is simple and the practicality is higher.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
