风力舂米机是以风为动力的舂米机模型。在小学自然教学中,可用它讲解风力、风车的构造及风的利用原理等内容。风力舂米机由底板、杵杆、舂杵、杵杆支架、贮米槽、曲轴、曲轴支架、连杆和风车等零件构成(如图1)。制作时需薄木板、铁皮、12号铅丝、16号铅丝、瓶塞和瓶盖等材料。杵杆可做成条形或圆柱形,长150～200mm。在杵杆中部表面横向挖一浅槽,作为固定杵杆用。底板可用薄木板制作,它的宽为100mm左右,长比杵杆长些即可。
Wind glutinous rice machine is a model of glutinous rice machine powered by wind. In the natural teaching of elementary schools, it can be used to explain the structure of wind power, the structure of windmills, and the principle of wind use. The wind glutinous rice machine is composed of a bottom plate, a boring bar, a rake, a boring bar bracket, a storage tank, a crankshaft, a crank support, a connecting rod, and a windmill and the like (see FIG. 1 ). Thin wood board, iron sheet, lead wire No. 12, lead wire No. 16, wire stopper and bottle cap are required for production. The mast can be made into a bar or a cylinder and is 150 to 200 mm long. A shallow groove is dug laterally on the middle surface of the mast to serve as a fixed mast. The bottom plate can be made of thin wood, its width is about 100mm, the length can be longer than the mast.
