The food eaten by livestock needs to be crushed to help better digestion and absorption. Straw is an indispensable raw material for feed. When preparing feed, a large amount of straw needs to be crushed. When crushing longer raw materials such as corn stalks, due to the small feed inlet and short length of domestic feed crushing devices, when crushing, after one end of the straw enters the crushing chamber, the feed inlet cannot support the other end of the straw, causing it to tilt downward and unable to automatically slide into the crushing chamber, resulting in the straw breaking and falling. In order to maintain the angle of the straw entering the crushing chamber, the operator needs to keep supporting the straw until the feed inlet can support the tilt angle of the straw. In this way, too much manpower will be consumed in the crushing process. Utility Model Content
