固沙植物自动扦插育苗机设计与试验OA

Aiming at the problems of high labor intensity,low efficiency and high cost of manual cuttings of sand-fixing plants,combining with the agronomic requirements of seedling cutting of sand-fixing plants,an automatic cuttings nursery machine for sand-fixing plants is designed,which mainly consists of crawler walking system and seedling system.The crawler traveling system adopts dual motor differential drive,and two distance sensors are installed on the same side of the vehicle body,which ensures the horizontal position of the vehicle body when taking cuttings through PID control.The nursery system consists of the cutting mechanism,seedling storage mechanism,transverse moving mechanism and longitudinal moving mechanism.The design of the seedling storage mechanism makes the laying distance of the vehicle body up to 32 m when it is fully loaded,and the main structural parameters of the other parts are determined by computational analysis.Finally,a physical prototype was made to evaluate the operational performance of the seedling robot,and the results show that the designed seedling machine can meet the actual seedling requirements with a cutting success rate of 93.8%for the seedling branches.
