[0022] Example 1

[0023] To address the aforementioned problems: existing straw crushing devices often fail to crush the straw finely enough, resulting in large, fragmented pieces that easily clog the discharge channel or the inside of the equipment, thus affecting the crushing efficiency. The crushing blades of existing straw crushing devices are mostly one-piece designs, requiring complete replacement after wear, which is cumbersome and costly. If not replaced in time, it will further exacerbate the problems of insufficient crushing and clogging.
