The conveying belt 503 drives the straw to move until the straw contacts the conveying pressure wheel 604. Under the elastic force of the tension spring two 603, the conveying pressure wheel 604 cooperates with the conveying belt 503 to clamp the straw. As the conveying pressure wheel 604 and the conveying belt 503 rotate, the straw is transported from the feed port 103 to the protective shell 102, thereby realizing automatic loading of the straw and keeping the operator away from the rotating knife holder 104, thereby improving the safety of the shredder when in use.

As the multiple movable cutters 107 rotate, the straw is continuously chopped. When the straw is chopped for a long time, the straw debris is easily stuck in the cutting groove 106. At this time, the volume of the cutting groove 106 becomes smaller, which will reduce the chopped length of the straw, or even completely block the cutting groove 106, so that the straw cannot extend into the cutting groove 106, thereby affecting the efficiency of straw chopping. Therefore, when the movable cutter 107 is away from the fixed cutter 109, the push shaft 205 contacts the fixed push rod 206, and the fixed push rod 206 pushes the push shaft 205 to move relative to the rotating tool holder 104.
