| Abstract: | The paper expounded thehinds of boat-type machines.Through theoretical analysis ,weexplained the theory of forming slurry-film lubrication under the bottom of the boat-type ma-chine and analyzedthe existing problem it is impossible to obtain full slurry film lubrica-tion water-pad under the bottom. Also we explained the theory of forming water-pad underthe bottom of the boat-type machine and corresponding technics,and applied it to theseedling boat of the rice transplanter and tank model. The result of verification showed thatthe sliding resistance was greatly reduced with the forming water-pad device fixed. |
