The invention relates to a mechanical automatic vinyl type material separation apparatus for selective separation of renewable and energy vinyl type material direct towards domestric garbage and recoverable garbage generated by families, which can solve various problems of the prior domestic garbage regeneration device that increased human powder to result into work load increase, the separation efficiency is reduced and the sanitary condition is deteriorated. The mechanical automatic vinyl type material separation apparatus can high-purity selectively separate the vinyl type material from the domestic garbage and the recoverable garbage, greatly improve the work load, work efficiency and the sanitary condition of the work personnel and increase the reutilization and energy recovery rate.The factors of a rotary harrow in the vinyl type material separation apparatus, such as the size, structure and arrangement, are adjusted. The vinyl type material separation apparatus not only separates the vinyl type material but also separates the renewable article such as PET bottle and prevents garbage winding or coagulating into one body therefore the vinyl type material separation apparatuscontinuously operates.
