Research and development of the rice rope direct seeding machine
Wentao Ren · Nanjing Nongye Daxue xuebao · 2010
Basic principles and key parameters of the main structure were analyzed on rice rope direct seeding machine.The parts′ structural design and assembly of the rice rope direct seeding machine were finished with UGNX.On the basis,rice rope direct seeding machine was developed.The machine consisted of anti-blocking device,sowing device,opening device,banking device,compacting device,and so on.Field test results showed that two difficult problems,easy pluggedness of opener and difficult adjustment of seed number in every hole,were solved effectively,and the machine had the advantage of good maneuverability and high working efficiency.Dynamic testing system was designed.Thickness of soil cover of rice rope direct seeding machine in the field was tested by the dynamic testing system.The test proves the prototype device has a good effect of the suppression,well balanced planting depth and uniform placement of the ropes.
