By setting the adjustment structure 6, personnel can move the wooden board stuck in the feed port 4 downward to prevent the wooden board from getting stuck in the crusher and affecting the operation of the equipment, thereby greatly improving the efficiency of the equipment in crushing the wooden board.

[0033] When personnel are crushing the wooden board, a small amount of wood chips after crushing will splash outward and cause harm to people. At this time, this problem can be well solved by setting up the auxiliary structure 7.
