Horizontal adjusting mechanism of precision seeding machine for field seedling raising

The invention discloses a horizontal adjusting mechanism of a precision seeding machine for field seedling raising, and mainly relates to the technical field of agricultural precision seeding machines. The horizontal adjusting mechanism of the precision seeding machine for field seedling raising comprises a one-translation and two-rotation shunt-wound mechanism formed by three different branch chains, a static platform and a mobile platform, wherein three sliding pairs are driving pairs. Through the adjustment of the three sliding pairs, the adjustment of the levelness of the vibrating seed plate of a seeder can be achieved. The utility model has the advantages that the rigidity of the mechanism is high, the bearing capacity is strong, the adjusting accuracy is high, a user can adjust the horizontal position of the seeder conveniently, and conditions for field seedling raising and seeding can be achieved.
