Abstract: Vegetable seed is easy to be damaged during sowing, which makes it difficult to sow, the mechanization level is still less than 10%. The backward precision sowing technology and imperfect equipment have caused serious obstacles to the development of the industry. Although the greenhouse technology can better cope with the external natural environment, and its coverage is also expanding year by year, the small vegetable planter used by it also has the problems of single model, low operation efficiency and poor mode adaptability. Based on this, it is necessary to carry out the research on vegetable precision seeder, so as to realize the machinery to improve production efficiency, enhance mode adaptability, and improve the mechanization level of vegetable seedling raising.
