[0002] A crusher is a device that breaks up fixed raw materials by using blades arranged on the surface of a crushing roller. When using the crusher, start the motor and drive a crushing roller to rotate through the motor. Because the two crushing rollers are fixedly connected to gears at one end away from the motor, and the two gears are meshed with each other, the motor can drive the two crushing rollers to rotate relative to each other. Then the straw is placed inside the main body of the crusher, and the blades arranged on the surface of the crushing roller can break up the straw well.

[0003] After completing agricultural work, the inventor discovered that there was a large amount of straw left. Since the entire straw is difficult to degrade quickly in the soil, it will affect later planting. If it is directly burned, it will cause environmental pollution. In order to increase the rapid degradation of the straw, a straw crusher is often needed to crush the straw. In daily work, it is found that the crusher still has at least the following problems: when the crusher is used, the feed port of the crusher is open, and then when the crushing roller cuts the straw, debris will splash out from the feed port, which will cause the place where the straw is crushed to become messy and require manual cleaning, which is troublesome.
