[0002] Grass crushers are mainly used for crushing crop straw and grass. The materials obtained from the crushing process can be directly used to feed poultry or livestock. Among them, the materials used to feed pigs, geese, etc. need to be crushed more finely, while the materials used to feed cattle, sheep, etc. do not need to be crushed too finely. Many farmers often raise a lot of poultry and livestock, and need to crush grass of different degrees of fineness. At the same time, corn often needs to be crushed. The current crushers cannot meet multiple crushing needs at the same time, and purchasing multiple crushers at the same time is costly and takes up space.
