秸秆切碎机 摘 要 秸秆是成熟农作物茎叶（穗）部分的总称。通常指小麦、水稻、玉米、薯类、油料、棉花、甘蔗和其它农作物在收获籽实后的剩余部分。农作物光合作用的产物有一半以上存在于秸秆中，秸秆富含氮、磷、钾、钙、镁和有机质等，是一种具有多用途的可再生的生物资源。对秸秆的饲料化处理，其首先的工序需将秸秆粉碎或切短。本设计喂入、切碎和抛送均采用自动化装置，以电动机为动力源，通过皮带传输动力到轴，带动轴上的刀的转动进行切碎，通过齿轮传动带动进料装置的工作，轴通过带传动带动抛送装置的工作，从而节省了人力。本设计的喂入装置中的压紧机构设计独特，实现了喂入秸秆过多时在喂入辊处不产生堵塞，过少时不产生碎段过长的现象。 关键词：  秸秆 切碎器 自动化 |
Design of the Straw Chopper Abstract Straw is the name given to stems and leaves of mature crops leaf. Usually refers to the rest of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvest seeds. More than half of Products of crop photosynthesis exists in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a kind of multi-purpose renewable biological resource. The first of the processes of animal's feedstuff is to crush or chop straw. The feeding, shredding and throwing all adopted automation equipment. It adopted electric motor as power source and delivered power to the axle through the belt to drive the knife of axle to chop. The feeding equipment worked through the gears operates and axle spurred throwing equipment through belt drives, thereby saving labor power. This project have several choice so that to suit the requirements of different livestock. Hold-down mechanism of feeding Device is a unique design to achieve no jam when feeding too much straw and no long straw when there are too little straw. Key words Straw Chopper Automation |
