The Design and Research on Spreading Soil Device of Rice Factory Seedlings

The spreading soil device of rice factory seedling has been designed. In study the V shape bulldozing plate drum dump structure has been designed that focused on the high quality requirements of the super rice seedlings, the diameter and length of the V shape bulldozing plate drum dump and the thickness M of the V shape bulldozing plate has been designed, a force model of the soil in the dumping course and analyze the effect of spiral and operate width of the V shape bulldozing plate to dump performance also has been established. Finally, the assembled reasonableness between the drum dump and other components has been established through the 3D solid modeling of Pro / E software. The thickness and uniformity of spreading soil has been guaranteed also the quality of seedling emergence has been ensured by designing the device.
