TECHNICAL FIELD

[0001] The present application relates to the technical field of seeding technology, and particularly relates to a seed quantity adjusting method and a seeding device adopting the same. BACKGROUND

[0002] At present, the existing seed seeding method mainly adopts a roller type seeder to seed, specifically, a seed taking mechanism composed of a seed taking nest, a seed inlet and a seed inlet channel is arranged in the roller type seeder, and a seed storage cavity and a seed outlet are arranged on the roller type seeder; the seed taking and seeding are realized by the seed taking mechanism with the rolling of the roller type seeder; in the process of taking seeds by the seed taking mechanism in the seeding area, two or more seeds in the seed storage cavity enter the seed taking nest through the seed inlet channel, and then the other seeds are removed; with the rolling of the roller type seeder, the seeds in the seed taking nest are discharged in the seeding area to realize the seeding.

[0003] However, in the process of taking seeds by the seed taking mechanism in the existing seed seeding method, the entering posture of the seeds is uncertain in the process of entering the seed taking nest, which easily causes the seeds to be blocked in the seed inlet channel, affects the smoothness of the seeds entering the seed taking nest, and easily causes the seeds to not enter the seed taking nest normally and appear the seed deficiency phenomenon, causing the uneven seedling in the later period.

[0004] Further, the seed taking nest takes two or more seeds with different quantities in one seed taking period, and the sizes of the seeds are different; in the rolling process of the roller type seeder, the postures and movement directions of the seeds stored in the seed storage cavity are chaotic, which causes the quantity of the seeds entering the seed taking nest to be uncertain, causes the quantity of the seeds seeded each time to be uncertain, and further causes the uneven seedling in the later period.

[0005] Further, the existing seed seeding method is not convenient for adjusting the seed seeding quantity according to the demand of different seeding lands for the seed seeding quantity, and the existing seed seeding method can only adjust the seed seeding quantity of the roller type seeder by changing the size of the seed taking nest to adjust the seed taking quantity of the seed taking nest, but this method for adjusting the seed seeding quantity of the roller type seeder needs to disassemble the whole roller type seeder, replace the seed taking mechanism with the seed taking nest of the suitable size to reform the roller type seeder, so that the difficulty and workload of the reform of the roller type seeder for adjusting the seed seeding quantity are large.

[0006] Further, in the process of seed taking, two or more seeds in the seed storage cavity can enter the seed channel at the same time, and the multiple seeds can be pressed against each other, which can easily cause the seed channel to be blocked, so that the seeds cannot enter the seed taking nest normally, and the seed taking nest can be blocked, and seed deficiency can occur, and seedling deficiency can occur in the later period.

[0110] The selected seed feeding guide slot shielding structure 4 is detachably connected to the connecting part, and the plurality of seed passing openings 401 are directly opposite to the plurality of seed feeding guide slots 311, so that the seed feeding guide slot shielding structure 4 shields the seed feeding guide slots 311 that have no seed passing openings 401 directly opposite to them on the seed feeding guide structure 3 on the side close to the inner side of the roller assembly 1.

[0111] In this embodiment, as shown in Figure 3 、 Figure 6 and Figure 7As shown, the seed quantity adjusting method is provided with a plurality of seed passing holes 401 on the guiding groove seed-feeding blocking structure 4, which facilitates the seed-feeding restriction on the seed-feeding guiding grooves 311 not directly opposite to the seed passing holes 401, so that each seed-feeding guiding structure 3 has a proper number of seed-feeding guiding grooves 311 for seed feeding, and then each seed-picking structure 2 has a proper number of seed-picking holes 23 for seed picking, storing and feeding.
