[0026] Embodiment:

[0027] Frame structure:

[0028] It includes a frame 10, which serves as the support and connection foundation for the entire seeder;

[0029] In the middle of the outer side of the front end of the frame 10, a tractor towing frame is provided, which includes a tractor bottom towing rod 11 horizontally arranged at the lower part and a tractor central towing rod 12 vertically arranged at the upper part, facilitating connection with the tractor and transmitting power;

[0030] At the lower part of the front end of the tractor central towing rod 12, a furrow opener fixing frame 13 is provided for installing the furrow opener 20 to realize the soil furrowing operation before sowing;

[0031] Furrow opener design:

[0032] The furrow opener 20 is fixedly connected to the furrow opener fixing frame 13. Its furrow opening wheel 21 can be selected as a disc type, a flower disc type or a manganese steel hook type to be used on different ground surfaces to complete various seeding operations. The working height of the furrow opener 20 can be adjusted up and down through the furrow opener fixing frame 13;

[0033] Seed storage and seeding system:

[0034] A seed storage bin 30 is arranged at the center inside the frame 10, which is divided into a seed storage chamber 31 on the left and right sides and a seeding chamber 32 in the middle. The seed storage chamber 31 is used to store seeds to be sown, and the seeding chamber 32 is responsible for evenly discharging the seeds;

[0035] Both ends of the seed storage bin 30 are connected with driving wheels 40 that move along the traction direction, and are rotatably connected to the connecting frames 14 at the lower ends of the left and right sides of the frame 10 through rolling shafts 50 to achieve stable movement during the seeding process;

[0036] Seed adding ports 33 are provided outside the seed storage bin 30 corresponding to the left and right seed storage chambers 31 for facilitating the replenishment of seeds; seed discharging holes 34 are provided above and below the corresponding seeding chamber 32 to control the discharge of seeds;

[0037] A sieve mesh 35 is arranged between the seeding chamber 32 and the left and right seed storage chambers 31 to prevent seed clogging and ensure uniform seeding (the sieve mesh can also not be installed for easier cleaning);

[0038] Design of the covering board:

[0039] A covering board 60 is arranged at the center outside the rear end of the frame 10. Its upper end is fixedly connected to the frame 10, and the other end is set on the ground for covering the seeds with soil after seeding to ensure close contact between the seeds and the soil.

[0040] Further technical features:

[0041] Design of the seed adding port:

[0042] A seed adding cover 331 is arranged at the seed adding port 33. One side end of it is hinged to the outer wall of the seed storage bin 30, and the other side end is connected by bolts, which is convenient for quick opening and closing and at the same time ensures the sealing performance of the seed adding port;

[0043] Structure reinforcement:

[0044] Connecting ribs 15 are arranged between the lower parts of the two ends of the left and right frames 10 and the lower ends of the two ends of the connecting frames 14 on the same side to enhance the overall stability and load-bearing capacity of the frame.

[0045] The working principle of this planetary rolling seeder is mainly based on its unique structural design and the coordinated action between components to achieve efficient seeding operations. The following is a detailed description of its working principle:

[0046] 1. Traction and power transmission

[0047] Tractor traction: The planetary rolling seeder is connected to the tractor through the tractor towing frame at the front end, and the tractor provides the forward power and traction force. The towing rod at the bottom of the tractor and the central towing rod ensure the stable travel of the seeder in the field and transmit the necessary power.

[0048] 2. Ditch opening operation

[0049] Operation of the ditch opener: As the seeder moves forward, the ditch opener (disc type or round tooth disc type) installed on the ditch opener fixing frame starts to rotate, cuts into the soil and opens up the grooves required for sowing. The design of the ditch opener ensures that the depth and width of the grooves are appropriate, which is conducive to the implantation and subsequent growth of seeds.

[0050] 3. Seed storage and sowing

[0051] Seed storage and transmission: The seeds in the seed storage bin are transmitted from the seed storage chamber to the sowing chamber by gravity. The sieve in the sowing chamber prevents seed clogging and ensures that the seeds can flow out evenly and continuously.

[0052] Sowing process: When the seeder travels to the preset position, the seeds fall into the opened grooves under the action of gravity.

[0053] 4. Covering

[0054] Function of the covering board: After sowing, the covering board on the outer side of the rear end of the frame covers the seeds in the grooves. This step is crucial for the growth of the seeds. It ensures the close contact between the seeds and the soil and provides a good environment for the germination and growth of the seeds.

[0055] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
