[0002] Sorghum is known as "the essence of the five elements and the leader of all grains" in the "Food Materia Medica". Its harvested area and total output are second only to wheat, rice and corn, and it is one of the four major cereal crops in the world. Blanket seedlings mean using the principle of inertial planting. Through the improvement and innovation of the non-circular planetary gear system and the cam push rod of the high-speed transplanter to form a transplanting mechanism, a new seedling picking and transplanting mechanism is developed, which forms a high-speed operating machinery suitable for orderly shallow planting of blanket seedlings with a four-wheel universal chassis, overcoming a series of problems such as mud.
