Description

Technical Field

[0001] The invention belongs to the technical field of agricultural sowing machinery, and in particular to a unit group hole sowing sowing disc and a working method thereof. Background Art

[0002] The hole seeding tray is often used in farmland operations; the hole seeding tray in the prior art also has the following defects:

[0003] The structure of the hole seeder in the seeding tray is inconvenient to operate when adjusting the seed amount; some hole seeders adjust the seed amount through rack linkage, and the adjusting rack is in the seed chamber. Since seeds are now coated, the rack and knob of the seed limiter will often get stuck and damaged; some hole seeders need to disassemble more parts when adjusting the seed amount, which is called "major disassembly" in the field. After adjustment, they are reassembled again, and the operation of adjusting the seed amount is cumbersome; for example: in the prior art, in some hole seeder structures, seed amount control is achieved by using a seed spoon. When adjusting the seed amount, the seed spoons of different models and sizes are replaced, and the seed spoons are installed inside the hole seeder. The hole seeder needs to be disassembled before the seed spoons can be replaced; it can be seen that the operation is relatively cumbersome; in addition, the slot plate diversion type hole seeder will have the problem of low hole formation stability rate when the sowing speed is relatively fast.

[0004] The cavity of the hole sowing tray can store seeds from the seed storage box; and the seeds need to be able to flow effectively in the sowing tray to ensure the quality of sowing. In the prior art, the connection structure or component arrangement between the seed inlet pipe and the sowing tray is unreasonable, and the cavity of the sowing tray often stores more than half of the seeds or is full, so that the seeds cannot flow into the hole sowing device effectively, and accurate sowing cannot be achieved.

[0005] In summary, the hole seeding disc in the prior art still has many defects when in use. Summary of the invention

[0006] The invention provides a unit group hole sowing seeding disc to achieve the purpose of stable hole formation and effective and accurate sowing.

[0012] Furthermore, the duckbill combination includes a fixed duckbill and a movable duckbill, wherein the fixed duckbill is welded to the mounting plate, and circular mounting holes are respectively provided in the fixed duckbill and the movable duckbill.

[0013] Furthermore, a groove is provided on one side of the limit block, the shape of the groove matches the shape of the fixed duckbill, is clamped on the fixed duckbill, and then fixed on the mounting plate.

[0014] Furthermore, the interlocking mechanism includes a interlocking rod and a return spring. The interlocking rod passes through the circular mounting hole to fix the movable duckbill on the fixed duckbill, and the return spring is sleeved on the interlocking rod. The interlocking rod is in a right-angle bend shape.

[0015] Furthermore, a groove is provided in the seed limiter, a perforated partition is installed in the groove, and the partition is fixed on the collector; in the seed limiter structure, a part is installed inside the collector, the seed inlet is outside the collector, and communicates with the oblong opening inside the seed limiter.

The adjustment knob is combined with the seed limiter to effectively solve the problem of the seed limiter being stuck or damaged, and the device has the advantages of high efficiency and stable hole formation.

[0025] In the structure of the present invention, the seeding structure under the middle shaft controls the seeding volume in the seeding tray chamber to not exceed one third, ensuring that the seeds can flow effectively, thereby ensuring that the seeds flow as the seeding tray rotates and can effectively enter the duckbill hole sowing device for seeding. In summary, the unit group hole sowing sowing tray provided by the present invention achieves the purpose of controllable seeding volume, convenient seeding volume adjustment, and effective seed flow and clear seed separation in the disc seed chamber.
