拨齿式电驱动水稻育秧盘起盘机设计与试验OA

For the northern rice seedling transplanting production mode of shed-type rice seedling transplanting process is not suitable for the laying of large gantry tray starting machinery,created a toggle gear type electric drive rice seedling tray starting machine.The machine's structure and working principle are explained,the basic principle of dialing up the rice seedling tray is clarified,the dialing device of the rice seedling tray starter is designed using mechanical analysis,and the structural parameters of the dialing mechanism and its range of values that affect the performance of the tray are determined.The results show that the better combination of parameters for the paddle gear type electric drive rice trans-planting tray starter is 40r/min for the paddle gear speed,0.8km/h for the machine speed and 0mm for the paddle gear height from the ground.The test results were verified,and the complete rate of the seedling tray was 99%,the efficiency was 362trays/hour,and the performance indexes of the machine met the requirements of tray starting operation.
