Description

Self-adaptive angle adjusting device of seeder Technical Field The utility model belongs to the technical field of seeders, and particularly relates to a self-adaptive angle adjusting device of a seeder. Background The electric seeder is used as the essential core mechanical equipment of modern agriculture, and has the core of seeding seeds to the proper depth of soil efficiently, accurately and uniformly, thereby laying a solid foundation for high and stable yield of crops. Current mainstream designs typically rigidly secure the planter to the chassis frame by a mounting bracket and bolts. However, this fixing method has a significant disadvantage in practical application, and when sowing, the farmland surface is generally rough. Because the planter is rigidly connected to the chassis, it is difficult to maintain a constant planting depth throughout the travel due to the lack of independent terrain adaptation. The phenomenon of serious uneven sowing depth not only directly causes precious seed waste, but also causes uneven emergence and large seedling growth vigor difference, and finally affects the overall yield potential. Therefore, there is a need for an adaptive angle adjustment device for a planter that solves the above-mentioned problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide a self-adaptive angle adjusting device of a seeder, which has the advantage of being capable of adapting to different terrains and seeding depths. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a seeder self-adaptation angle adjusting device, includes walking chassis frame, installation pole, mounting bracket and disseminator mount pad, the mounting bracket links to each other with the disseminator mount pad is articulated, the disseminator mount pad passes through on the horse riding clamp and bolt fixed mounting on the installation pole be equipped with the angle modulation locking mechanical system that is used for adjusting the mounting bracket angle between mounting bracket and the disseminator mount pad. The seeder has the advantages that the seeder is hinged with the seeder mounting seat through the mounting frame and is provided with the angle adjusting and locking mechanism, and the angle of the mounting frame can be adjusted according to actual seeding requirements, so that the angle of the seeder can be adjusted, and meanwhile, the seeder can adapt to the requirements of different terrains and seeding depths, and the adaptability and the flexibility of seeding are improved.
