Simulation and Experimental Research on Rare-planting Separating-transplanting Mechanism of High-efficiency Rice Transplanter
摘要
Abstract
Aiming at the sparse planting requirement of the row spacing, the sparse planting transplanting mechanism based on a double jib arm type of the differential motion elliptical gear transmission was put forward, which is fit for transplanting the row spacing from 200 mm to 280 mm and the seedling height less than 350 mm.The kinematic model of the transplanting mechanism is established, and the angle relation between the gears of the differential elliptic gear train is deduced.According to the established kinematics model of the sparse planting transplanting mechanism.SolidWorks was used for the 3D modeling of the sparse planting transplanting mechanism, and verifying the assembly relations and structural design.The dynamics simulation of the transplanting mechanism is carried out by the ADAMS software, and the trajectory, velocity and acceleration of the seedling pinpoint and the meshing force of the elliptical gears and the center axle torque curve of the gear box are obtained.The motion trajectory and attitude measure experiment of the sparse planting transplanting mechanism prototype are carried out based on the image processing.The experimental results show that the test results obtained are consistent with the theoretical analysis results.关键词
