Description

Technical Field

[0001] The invention relates to the technical field of sowing technology methods and sowing equipment, and in particular to a seed taking and sowing anti-stuck method for a seeder and a seeder. Background Art

[0002] Wheat is a high-density crop, and a moderate planting density is beneficial to improving the uniformity of wheat growth, enhancing wheat's resistance to lodging, and also beneficial to increasing wheat yield; in order to improve the appropriateness of wheat planting density in the prior art, a seed collection and sowing method based on a hole seeder is adopted for sowing, and in the process of sowing wheat, it is necessary to implement the placement of a suitable number of wheat seeds in each wheat hole; therefore, before the wheat seeds are put into the soil, a seed collection mechanism arranged in the hole seeder is required to take out a suitable number of wheat seeds at the seed collection position, and then the wheat seeds obtained at the seed collection position are placed through a hole seeder nozzle arranged on the hole seeder, and then the seeds are put into the soil.

[0003] Furthermore, the hole-seeding device mainly includes a roller assembly, a seed-taking mechanism and a seed hole-seeding component. A seed storage cavity for storing seeds is formed in the roller assembly. The seed-taking mechanism is mounted on a supporting wheel body on the roller assembly. The seed-taking mechanism mainly includes a seed-taking device, a rotating shaft, a swing arm and a torsion spring. The seed hole-seeding component is mounted on the outer wheel surface of the supporting wheel body. Furthermore, in order to reduce the production and manufacturing cost of the hole-seeding device, a plurality of wheel body assembly units are usually obtained by manufacturing, and then the plurality of wheel body assembly units are assembled to obtain a ring-shaped supporting wheel body. Furthermore, a radial inner side of the wheel body assembly unit is provided with a circumferential interval. A mounting groove body is used for installing a seed remover, a seed remover is rotatably installed in the mounting groove body, the seed remover is installed on a rotating shaft, a torsion spring is sleeved on the rotating shaft, and a torsion arm 1 on the torsion spring stops against the seed remover, and a torsion arm 2 on the torsion spring stops against the supporting wheel body, one end of the rotating shaft is connected to the swing arm, and a swing drive rail is also provided in the roller assembly, and the swing drive rail, the swing arm and the torsion spring cooperate to drive the seed remover to rotate in the mounting groove body; a seed removal nest is provided on the seed remover, and the seed remover rotates in the mounting groove body so that the seed removal nest is deflected to have a seed removal position and a seed throwing position, the seed removal nest is used to remove seeds at the seed removal position, and the seed removal nest is used to throw seeds at the seed throwing position.

[0004] Furthermore, in order to realize seed cleaning by the hole sowing device, the seeds that have not fallen into the seed taking nest are blocked and cleared during the seed taking process by the seed taking device, so that only the seeds that have fallen into the seed taking nest are deflected from the seed taking position to the seed throwing position and dropped. Therefore, it is necessary to install an elastic seed cleaning member on one side of the mounting groove body, the elastic seed cleaning member is installed on the inner wheel surface and is located on one side of the seed taking device. In the process of the seed taking device being deflected from the seed throwing position to the seed throwing position, the elastic seed cleaning member sweeps over the outer wall of the seed taking device, and blocks and clears the seeds that have not fallen into the seed taking nest; in addition, the supporting wheel body is provided with a plurality of seed dropping channels corresponding to the plurality of mounting grooves one by one, and the plurality of seed dropping channels are respectively connected with the mounting grooves, and the outer sides of the seed dropping channels pass through the supporting wheel body to form a seed dropping opening, and the outer sides of the seed dropping opening are respectively installed with hole sowing nozzles, and the timing of sowing is controlled by controlling the opening timing of the hole sowing nozzles, so as to realize the dropping of seeds into the seed dropping opening by the seed taking device.

[0005] However, wheat seeds vary in size, and the rolling conditions of the hole seeder are relatively complex. The movement of wheat seeds in the seed collection nest of the seeder is still uncertain. In practical wheat sowing operations, due to deficiencies in the design of the wheel assembly unit and the seed collection component, the hole seeder is prone to seed jamming and seed row shortage problems, which are not easy to be discovered during the sowing process. It is not until the wheat grows that it is discovered that there are few seeds in the wheat holes, resulting in few seedlings, or even missing seeds, resulting in missing seedlings, which has an adverse effect on the appropriateness of the wheat planting density and the wheat yield. Based on this, our company has found through research that when the seeds stored in the seed collection nest are passed through the elastic seed cleaning piece, The seeds stored in the seed taking hole are easy to move out of the edge of the seed taking hole, especially when there are multiple wheat seeds stored in one seed taking hole. The wheat seeds stored in the seed taking hole are stuck in the gap between the outer wall of the seed taking hole provided on the seed taking device and the inner wall of the surrounding side of the installation groove body due to the movement out of the edge of the seed taking hole, which is easy to cause seed jam, so that the corresponding seed taking device cannot normally cast seeds, and even cause the corresponding seed taking device to be abnormal in subsequent seed taking and casting, resulting in seed jamming problems in the hole sowing device and seed shortage problems in the sowing row; in addition, the existing hole sowing device also has the above-mentioned seed jamming problems and seed shortage problems in the sowing row when sowing soybeans and other types of seeds. Therefore, there is an urgent need for a seed taking and casting method that is conducive to avoiding the seed jam problem of the seeder during the process of taking and casting seeds.
