In the process of Vegetable Planter, the nutritional seedlings are easy to be injured by the planter during the falling process, the poor standing of the nutritional seedlings, and the speed of the planter movement when the seedlings are planted have a direct impact on the survival rate of the nutritional seedlings. The problem is to design a crank connecting rod type cutting mechanism. The trajectory, displacement, speed and acceleration of specific connecting rods and points in the mechanism have important effects on the vegetable planting mechanism.

We design the vegetable planting machine and perform kinematics simulation analysis on the end effector. It is of practical significance to further develop a vegetable planter with excellent performance. This article mainly focuses on the planting mechanism, seedling dividing mechanism and seedling feeding mechanism of the vegetable planting machine. Establish a mathematical model for theoretical design, parameter optimization, and verify feasibility. Then, through the establishment of a three-dimensional model of the whole machine, it is checked whether the parameter design of each mechanism is reasonable and whether there is interference in each mechanism. After re-modifying the unreasonable mechanism, the reasonable three-dimensional model is imported into the system simulation software to perform kinematics and dynamics simulation. analysis.

Analyze whether the end effector of the vegetable Planting Machine can carry out the planting operation according to the preset, theoretically analyze the design rationality of the planting mechanism; analyze whether the force exerted by the seedling dividing mechanism and the movement speed on the nutrient seedlings will cause mechanical damage to the nutrient block; analysis Whether the seedling delivery institution is in accordance with the theoretical situation.
