对我国古代踏碓的再认识OA

Based on the paper An Investigation and Interpretation of Pedal Threshers in Farm Tools Atlas,some views for discussion are put forward.There was no sideways single-bar handrail type trip-hammer in ancient China,and there was no trip-hammer using laborer's weight by sitting on the pestle or sitting to tread.There was one kind of trip-hammer with a rope tied to the head of the pestle to assist in pulling,which is still used in modern times.There was no trip-hammer with double fulcrums,and the type of trip-hammer with a shaft and two supports forming a rotating pair has been the dominant form since the Han Dynasty.In the study of the history of science and technology,two principles should be adhered to:special claims require caution,and the citation of historical materials should be rigorous.
