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
