Design and experiment of power chassis for pneumatic centralized rice direct seeding machine
In view of the situatiou of unstructured working environment,working object biological nature and working func-tion complexity of rice direct seeding,the profiling anti-slip multi-functional power chassis for pneumatic centralized rice di-rect seeding machine is designed,including multi-functional frame,pressure cylinder and opener and other parts.The key components of centralized pneumatic rice direct seeding machine power chassis are analyzed in the static structure,dynamic structure and gravity center.The resonance frequency of power chassis and tractor is calculated by using the six-order modal vibration mode finite element analysis,and the rationality of the design is verified.The field experiment results show that the coefficient of variation of inter-row seeding was 4.27～6.16%,realizing the trenching,covering,pressing and profiling inte-grated operation of the direct seeding machine,and the chassis slip rate was 7.68%,which meets the requirements of sta-bility and work efficiency of the pneumatic centralized rice direct seeding machine.
