| Abstract: | Based on different planting conditions and sowing time in the same place and according to different requirements of rape seeding density,the mechanism for variable sowing on 2BFQ-6 rape precision combined direct planter has been designed,depending on the theory that adjusting the engaging relations of gears can change the input shaft's speed of the metering device.Its structure and working principle were studied in this paper,and it has the regulatory function with four planting densities.At the same time s... |
