Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model aims to provide a roller type finger-clamp precision seed drill to solve the problems existing in the above-mentioned related technologies, enhance the protection of seeds during the seeding process, and improve the seeding efficiency.

[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Embodiment 1

[0033] This embodiment provides a roller type finger clamp precision seeding device 100, please refer to Figure 1-Figure 5 , including a fixed cam 1, a main frame 2 and a seed taking component 3, wherein the fixed cam 1 can be connected to other fixed structures of the seeder; the main frame 2 is rotatably sleeved on the outside of the fixed cam 1, and the main frame 2 has a storage space for accommodating seeds, and the outer peripheral surface of the main frame 2 is provided with a seed outlet 4; a plurality of protective shafts 5 are arranged in the storage space, the protective shafts 5 are rotatably connected to the main frame 2, and the outer peripheral surface of the protective shafts 5 is provided with a protective structure layer 6, and the protective structure layer 6 is made of elastic material; the seed taking component 3 is arranged between the main frame 2 and the fixed cam 1, and the seed taking component 3 includes a fixed plate 7, a connecting rod 8 and a seed taking block 9, the fixed plate 7 is an L-shaped structure, the middle part of the fixed plate 7 is hinged to the main frame 2, and the other end of the fixed plate 7 is connected to one end of the connecting rod 8 The ends are hinged, the seed taking block 9 is hinged with the main frame 2, and the side of the seed taking block 9 away from the fixed cam 1 is provided with a seed taking groove 10, and the end of the connecting rod 8 away from the fixed plate 7 is against the seed taking block 9 and can push the seed taking block 9 to rotate, and a twist spring is provided at the rotating connection between the fixed plate 7 and the main frame 2, so that the fixed plate 7 can use the connecting rod 8 to press the seed taking block 9 against the main frame 2, and fix the seeds in the space between the seed taking groove 10 and the main frame 2 to realize seed taking. When the fixed plate 7 is rotated to press against the protrusion of the fixed cam 1, the fixed plate 7 can pull the connecting rod 8 to separate the part of the seed taking block 9 pressing against the main frame 2 from the main frame 2; the number of seed taking components 3 is multiple groups, and the seed taking components 3 are circumferentially arranged around the axis of the fixed cam 1, and the seed taking components 3 correspond to the seed outlet 4 one by one.

[0034] The roller-type finger-clamp precision seed drill 100 of the utility model delivers seeds into the storage space, and the main frame 2 rotates relative to the fixed cam 1, so that the seed taking component 3 can complete the cycle operation of taking seeds and sending them out for sowing. Multiple groups of seed taking components 3 are provided to improve the sowing efficiency. It should be emphasized that the utility model is provided with a protective shaft 5 in the storage space, and the protective shaft 5 is rotatably provided in the storage space, and a protective structure layer 6 is provided outside the protective shaft 5. In the process of rotating and collecting seeds, by providing the protective structure layer 6 of elastic material, the collision between seeds can be effectively reduced, the protection effect on seeds can be enhanced, and the sowing efficiency can be improved.

[0035] Specifically, the outer peripheral surface of the fixed cam 1 has a first raised section 11, and the first raised section 11 is set downward. When the fixed plate 7 rotates until it abuts against the first raised section 11, the fixed plate 7 rotates relative to the main frame 2 to pull the connecting rod 8, and the seed removal block 9 is separated from the main frame 2, and the seeds in the seed removal groove 10 fall into the seed outlet 4. When the main frame 2 drives the fixed plate 7 to rotate until it contacts the first raised section 11, the fixed plate 7 rotates relative to the main frame 2 and pulls the connecting rod 8, and the connecting rod 8 drives the seed taking block 9 to rotate, so that the part of the seed taking block 9 that presses against the main frame 2 is separated from the main frame 2, and the seeds in the seed taking groove 10 fall into the seed outlet 4 under the action of gravity; after the seeds in the seed taking groove 10 are sent into the seed outlet 4, the main frame 2 continues to drive the fixed plate 7 to rotate, and after the fixed plate 7 is separated from the first raised section 11, the fixed plate 7 is gradually reset under the elastic force of the torsion spring, and the seed taking block 9 rotates to support the seeds when the seed taking groove 10 is upward, and the seed taking block 9 presses against the main frame 2, and the seed taking block 9 cooperates with the main frame 2 to clamp the seeds to achieve seed taking, until the fixed plate 7 moves to the first raised section 11 again, and the seeds are sent into the seed outlet 4. It needs to be explained here that according to the specifications of the main frame 2 and the seed taking component 3, the outer peripheral surface contour shape of the fixed cam 1 and the size of the first raised section 11 are reasonably set to meet the requirements of seed taking and seed transporting when the seed taking component 3 moves to a certain position. This is a common practice for those skilled in the art and will not be repeated here.

[0036] In this specific embodiment, the outer peripheral surface of the fixed cam 1 also has a second raised section 12, and along the rotation direction of the main frame 2, the second raised section 12 is located in front of the first raised section 11. When the fixed plate 7 moves to the second raised section 12, the connecting rod 8 drives the seeding block 9 to rotate, and the part of the seeding block 9 that is previously pressed against the main frame 2 is separated from the main frame 2, that is, the seeding groove 10 is separated from the main frame 2, but at this time, the seeding groove 10 is in a roughly horizontal position. Although the main frame 2 cannot clamp the seeds with the seeding groove 10 at this time, the seeding groove 10 is still able to support the seeds to prevent the seeds from falling, and can also make the excess seeds fall, avoid taking too much seeds, and meet the seeding needs. It needs to be explained here that roughly horizontal specifically refers to the angle between the seeding groove 10 and the horizontal plane is 0 degrees or the angle of the angle is small, so that the seeds in the seeding groove 10 will not fall.

[0037] At the same time, there is a recessed section 13 between the first raised section 11 and the second raised section 12, and the surfaces where the first raised section 11 and the second raised section 12 are connected to the recessed section 13 are all cambered surfaces. When the fixed plate 7 moves to the recessed section 13, it rotates under the elastic force of the twist spring, and uses the connecting rod 8 to apply force to the seed removal block 9, so that the seed removal block 9 vibrates, and the vibration effect can also achieve the purpose of removing excess seeds in the seed removal groove 10. The surfaces where the first raised section 11 and the second raised section 12 are connected to the recessed section 13 are all cambered surfaces, which prevents the fixed plate 7 from getting stuck and ensures the working reliability of the seed removal component 3.

[0038] In practical applications, the rotation axis of the protection shaft 5 is parallel to the rotation axis of the main frame 2, and the protection shaft 5 is arranged circumferentially around the axis of the main frame 2 to provide protection for the seeds during the rotation of the main frame 2. In practical applications, the distribution and size of the protection shaft 5 can be adjusted according to different seed specifications, thereby improving the flexibility and adaptability of the device while protecting the seeds.

[0039] More specifically, the protective structure layer 6 is detachably connected to the protective shaft 5, which is convenient for disassembly and replacement after the protective structure layer 6 is worn. Accordingly, the protective shaft 5 and the main frame 2 can also be detachably connected to facilitate adjustment of the distribution of the protective shaft 5.

[0040] In other specific embodiments of the present invention, the protective structure layer 6 is sleeved on the outside of the protective shaft 5 for easy disassembly and assembly. The protective structure layer 6 can also be a structure in which a strip is wrapped around the outside of the protective shaft 5 for easy replacement.

[0041] It should also be noted that the seed removal block 9 has a connecting groove 14, and the end of the connecting rod 8 away from the fixed plate 7 extends into the connecting groove 14, and the connecting groove 14 is a V-shaped groove. The connecting rod 8 extends into the connecting groove 14 to push the seed removal block 9. When the relative angle between the connecting rod 8 and the seed removal block 9 changes, the connecting rod 8 can also use the side wall of the connecting groove 14 to push the seed removal block 9.

[0042] In this specific embodiment, a central axis connecting block 15 is provided in the main frame 2 to facilitate the installation of the fixing plate 7 , and a storage space is formed between the central axis connecting block 15 and the inner wall of the main frame 2 .

[0043] Furthermore, the roller-type finger-clamp precision seed drill 100 of the utility model further includes an outlet assembly 16, which is arranged at the seed outlet 4 and connected to the outer peripheral surface of the main frame 2, and the outlet assembly 16 has a flat outlet channel, the inlet of the outlet channel is connected to the seed outlet 4, and the outlet size of the outlet channel can be adjusted. The seeds transported by the seed outlet 4 enter the outlet channel, which further facilitates sowing. In actual application, the outlet assembly 16 contacts the soil, and the outlet size of the outlet channel can be adjusted to smoothly bury the seeds in the soil.

[0044] In this specific embodiment, the outlet assembly 16 includes an outlet connection plate 17 and a fixed channel plate 18 and a movable channel plate 19 arranged on the outlet connection plate 17. The outlet connection plate 17 is connected to the main frame 2, and the outlet connection plate 17 has a through hole matching the seed outlet 4. The fixed channel plate 18 is connected to the outlet connection plate 17, and the movable channel plate 19 is hinged with the fixed channel plate 18 and the two surround the outlet channel. A fixing rod 20 is set between the movable channel plate 19 and the fixed channel plate 18 to lock the relative position of the two. When the size of the outlet channel needs to be adjusted, the angle between the movable channel plate 19 and the fixed channel plate 18 is adjusted, and the fixing rod 20 is used to lock it after adjustment. In order to facilitate operation, a pressing sheet 21 can be set on the movable channel plate 19 to facilitate rotation operation.

[0045] In addition, it should be noted that the main frame 2 can be driven by other structures of the seed drill to achieve rotation. In order to facilitate the smooth transmission of torque, the main frame 2 is connected to an external disc 22, which can be connected to the driving source transmission to drive the main frame 2 to rotate smoothly.

[0046] In the roller-type finger-clamp precision seed drill 100 of the utility model, when the main frame 2 rotates, when the seeds pass through the seed collecting block 9, the seed collecting block 9 collects the seeds. During the rotation of the main frame 2, the seeds are sent out along the seed collecting block 9. During the process of seed rotation and collection, the setting of the protective structure layer 6 can effectively reduce the collision between seeds and improve the seeding efficiency.

[0047] Embodiment 2
