On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0054] like Figures 1 to 18 As shown, the embodiment of the utility model provides a handheld plug tray seeder, comprising:

[0055] A first housing 1;

[0056] A second shell 2 connected to the first shell 1;

[0057] A running wheel 3 movably connected to one side of the second shell 2; the running wheel 3 is movably connected to one side of the first shell 1;

[0058] A driving gear 4 connected to the travel wheel 3;

[0059] a driven gear 5 meshing with the driving gear 4;

[0060] A seeding wheel 6 connected to the driven gear 5;

[0061] A handle 7 connected to the end of the first shell 1;

[0062] A guide baffle 8 connected to the first shell 1;

[0063] A cover 9 is rotatably provided at one end of the first housing 1;

[0064] A sealing cover plate 10 connected to the first housing 1, wherein the sealing cover plate 10 is arranged inside the seeding wheel 6;

[0065] A spring sheet 11 connected to the sealing cover plate 10;

[0066] A sowing brush 12 connected to the sealing cover plate 10;

[0067] A cleaning brush 13 connected to the first shell 1 .

[0068] In this embodiment, the first shell 1 and the second shell 2 are connected by bolts to position the other parts of the seeder to ensure the cleanliness of the working space of the seeder parts; one side of the walking wheel 3 is movably connected to the second shell 2, and the other side is movably connected to the first shell 1. The first shell 1 and the second shell 2 wrap the walking wheel 3, and the walking wheel 3 can rotate axially. The walking wheel 3 is embedded in the driving gear 4, and the driving gear 4 is meshed with the driven gear 5. The sowing wheel 6 is connected to the driven gear 5. The driving gear 4 and the driven gear 5 form a mechanical fit to drive the sowing wheel 6 to rotate proportionally. The first shell 1 and the second shell 2 wrap the sowing wheel 6, and the sowing wheel 6 is coaxially connected to the center hole of the seeder shell and can rotate.

[0069] The seeding wheel 6 is fixed in position by the first shell 1 and the second shell 2, and can be driven to rotate by the walking wheel 3 through the mechanical transmission of the driving gear 4 and the driven gear 5. When the radial openings of the first shell 1 and the second shell 2 are selected to a specific position, they are connected to the seed outlet channel of the first shell 1 to complete the seeding process. By replacing the seeding wheel 6 with different opening diameters and wall thicknesses, mechanized seeding of flaky seeds such as eggplant, pepper, tomato and spherical seeds such as radish, cabbage, rapeseed can be achieved.

[0070] The driven gear 5 is embedded and matched with the seeding wheel 6, and is driven to rotate by the driving gear 4 to realize the rotation of the seeding wheel 6. The handle 7 is connected to the first shell 1 of the seeding device by bolts, which is convenient for holding during seeding operations; the guide partition plate 8 is connected to the first shell 1 of the seeding device to ensure the isolation of the driven gear 5 and the seed storage space. The first shell 1 and the second shell 2 wrap the cover 9, which can be rotated along the rotating shaft to open for seed addition; the sealing cover plate 10 is connected to the first shell 1 by bolts to keep the seed outlet channel closed. The sealing cover plate 10 is arranged inside the seeding wheel 6, and the spring piece 11 is connected to the sealing cover plate 10 to ensure that the seeds fall from the first through hole 14 of the seeding wheel 6. The seeding brush 12 is connected to the sealing cover plate 10 and fixed in position by bolts. The seeding wheel 6 is in close contact with the seeding brush 12 to control the seeding amount; the cleaning brush 13 is connected to the first shell 1 and fixed in position by bolts to keep the outer side of the walking wheel 3 clean.

[0071] The technical solution of the utility model realizes sowing operations of 72-hole, 128-hole and other seedling trays by replacing the walking wheel; the sowing wheel can also be replaced to adapt to different seeds for sowing operations of the seedling tray; the utility model has a small size, a simple structure and flexible operation.

[0072] 72 holes means that there are 72 grids in the seedling tray. The general seedling tray is 54cm long and 28cm wide. The difference is that the number of grids is different under the same area. The larger the grid, the fewer grids there are, and the smaller the grid, the more grids there are. The number of holes is determined by the number of grids. The general specifications are 32 holes, 50 holes, 72 holes, 105 holes, 128 holes, and 200 holes.

[0073] In an optional embodiment of the present utility model, the seeding wheel 6 is an annular structure;

[0074] The seeding wheel 6 is provided with a plurality of first through holes 14 at intervals, and seeds are sown through the first through holes 14 .

[0075] In this embodiment, the seeding wheel 6 is provided with a plurality of first through holes 14 at intervals. The diameter of the first through holes 14 mainly depends on the size of the seeds. To ensure that the seeds can smoothly fall into the hole tray, the diameter of the first through holes 14 should be slightly larger than the maximum diameter of the seeds. For example, for small vegetable seeds (such as lettuce, spinach, etc.), the diameter of the first through holes 14 can be between 2-4 mm.

[0076] In an optional embodiment of the present invention, the wall thickness of the seeding wheel 6 is set according to a first preset requirement.

[0077] In this embodiment, the diameter and thickness of the seeding wheel 6 are determined according to the overall design and use requirements of the seeding device, and the diameter may range from a few centimeters to tens of centimeters, depending on the size of the seeding device and the seeding area to be covered. The thickness must ensure that the seeding wheel has sufficient strength and rigidity to withstand various forces and impacts during the seeding process, while also considering lightness and manufacturing cost. For example, the wheel wall thickness can be selected to be 1-3 mm, preferably 1.5 mm.

[0078] In an optional embodiment of the present invention, a plurality of protrusions 15 are evenly arranged on one side of the travel wheel 3 .

[0079] In this embodiment, a plurality of convex points 15 are evenly arranged on one side of the walking wheel 3. The outer convex points 15 of the walking wheel 3 correspond to the hole type of the seedling tray, so as to realize the sowing operation of the seedling tray with 72 holes and 128 holes. The convex points 15 can be set to a diameter of 20 mm, and can also be adjusted according to actual needs. The convex point design can significantly increase the contact area between the walking wheel and the sowing ground (such as soil, seedbed, etc.), thereby enhancing the friction force, making the seeder more stable during walking, and reducing the possibility of sliding or offset. In the sowing operation, the walking wheel will inevitably press over the soil. The presence of the convex points can disperse the pressure of the walking wheel on the soil to a certain extent, reduce the degree of soil compaction, and help protect the soil structure and promote the germination and growth of seeds. The convex points may also have a certain guiding effect, helping the walking wheel to maintain a stable walking track on uneven ground, and improving the accuracy and efficiency of sowing.

[0080] The specifications of the bumps need to match the size of the travel wheel to ensure that they are reasonably distributed on the travel wheel, neither too dense to increase the travel resistance nor too sparse to lose their proper function;

[0081] The hardness and humidity of the sowing ground will also affect the selection of the bump specifications. For example, on harder soil, larger bumps may be needed to increase friction, while on softer soil, smaller bumps may be needed to reduce damage to the soil.

[0082] Different crops have different requirements for sowing accuracy, which may also affect the selection of bump specifications. For example, for crops that require precise sowing, denser bumps may be required to improve walking stability.

[0083] In an optional embodiment of the present invention, the protrusion 15 is in a circular, square, or conical shape.

[0084] In this embodiment, the circular protrusion is one of the most common shapes because it is simple and easy to manufacture; the circular protrusion can evenly disperse the pressure of the walking wheel on the soil and reduce soil compaction; at the same time, the circular protrusion has good rolling performance, which helps the walking wheel to move stably on uneven ground.

[0085] Square nubs are also available and may appear in some designs, and their shape may help provide better grip in certain soil conditions.

[0086] Conical bumps may also be used. The design of the conical bumps may be intended to increase the contact area and friction with the soil through their sharp apex, thereby improving walking stability; the conical bumps may also help provide better grip in soft soil.

[0087] In order to meet specific usage requirements or soil conditions, the protrusions on the travel wheels may also be designed to be irregular shapes; these irregularly shaped protrusions may combine the characteristics of multiple shapes to achieve better walking effects.

[0088] In an optional embodiment of the present invention, a first slot 16 is provided at one end of the first shell 1 , and the cleaning brush 13 is connected to the first shell 1 through the first slot 16 .

[0089] In this embodiment, a first card slot 16 is provided at one end of the first shell 1, and the cleaning brush 13 is connected to the first shell 1 through the first card slot 16. The cleaning brush 13 is in close contact with the walking wheel 3 to keep the outer side of the walking wheel 3 clean; the cleaning brush 13 is connected to the first shell 1 by bolts, and the height can be adjusted to adapt to walking wheels 3 of different specifications. The cleaning brush 13 is in close contact with the outer side of the walking wheel 3 to clean off the matrix soil and the like adhered to the walking wheel 3 from the seedling tray during the sowing process, so as to keep the walking wheel 3 and the seeder clean.

[0090] In an optional embodiment of the present invention, a second slot 17 is provided at one end of the sealing cover plate 10 , and the spring piece 11 is connected to the sealing cover plate 10 via the second slot 17 .

[0091] In this embodiment, a second slot 17 is provided at one end of the sealing cover plate 10 , and the spring piece 11 is connected to the sealing cover plate 10 via the second slot 17 , so as to ensure that the seeds fall from the first through hole 14 of the seeding wheel 6 .

[0092] In an optional embodiment of the present utility model, the sealing cover plate 10 includes a first sub-portion 18 and a second sub-portion 19;

[0093] The first sub-portion 18 and the second sub-portion 19 are integrally formed;

[0094] One end of the first sub-portion 18 is slidably connected to the inner side of the seeding wheel 6;

[0095] The first sub-portion 18 is connected to the first housing 1 by bolts.

[0096] In this embodiment, the sealing cover plate 10 includes a first sub-portion 18 and a second sub-portion 19 which are integrally formed; the sealing cover plate 10 is connected to the first housing 1 by bolts to keep the seed outlet passage closed.

[0097] In an optional embodiment of the present invention, one side of the guide partition plate 8 is connected to the seeding wheel 6 in sliding contact.

[0098] In this embodiment, one side of the guide partition plate 8 is connected to the seeding wheel 6 in sliding contact, thereby ensuring isolation between the driven gear 5 and the seed storage space.

[0099] In the specific implementation process, the device is generated by 3D printing materials, with fast molding and good effect;

[0100] The first housing 1 is connected to the second housing 2 by bolts, so that parts such as the walking wheel 3 and the seeding wheel 6 are wrapped in a relatively closed space, ensuring that the working space of the seeding device parts is clean.

[0101] The running wheel 3, the outer convex point 15 of the running wheel 3 corresponds to the hole type of the seedling tray, and the sowing operation of the seedling tray with 72 holes and 128 holes can be achieved by replacing the sowing wheel 6.

[0102] The seeding wheel 6 is fixed in position by the first shell 1 and the second shell 2, and can be driven to rotate by the walking wheel 3 through the mechanical transmission of the driving gear 4 and the driven gear 5. When the radial opening of the seeding wheel 6 is selected to a specific position, it is connected with the seed outlet channel of the first shell 1 to complete the seeding process. By replacing the seeding wheel 6 with different opening diameters and wall thicknesses, mechanized seeding of flaky seeds such as eggplant, pepper, tomato and spherical seeds such as radish, cabbage, rapeseed can be achieved.
