2、较广泛、可靠，且皮带具有自保护作用。机构的通用简单也增加了机器的可维护性，破 包机的成本不高，在农村市场可以很好的推广。 【关键词】 秸秆 破碎 辊子 链传动 滚筒 【Abstract】The pack-broken machinery is a kind of agricultural machine which breaks bundles of straw,It is composed of the transport operators, broken fixtures and racks. Transport operators have to maintain a constant

3、 and slow pace of delivery of straw bag, straw bag into the broken device, broken tool would break straw bags into clastic and play the knocked and loose straw predetermined position. The process of feed and breaking packets carry through simultaneously. Transportation system makes use of roller tra

4、nsport means, this approach is convenient, practical, and reliable; The broken tool breaks straw bag by the rotary axis of the high-speed and the large inertia. The machine is driven by two power systems, machine spindle system and the feed system. Feed motor chooses a lower speed, through a cycloid pin gear reducer to be a great spin-down ratio, bring along the sprocket to drive the roller. The spindle uses belt to drive
