A Study on Cleaning Buildup Soil in Loader Shovel on the Principle of Bionics

A device used for cleaning buildup soil in loader shovel was designed on the principle of Bionics. Kinetic and mechanical analyses are carried out for the device. A method of optimizing its structure is given. Its model device is tested and its real device is used for spadding soil and coal. It is shown that the device optimized in structure possesses an excellent property of cleaning buildup soil and its productivity is raised by 20 per cent.
