This utility model discloses a
pebble crushing device, including a
machine body and a moving
crocodile assembly including a moving
crocodile mounting body. A moving
crocodile plate is detachably mounted on the surface of the moving crocodile mounting body. The top of the moving crocodile mounting body is connected to a driving device. At least one
elbow plate is rotatably mounted on the lower end of the side of the moving crocodile mounting body away from the moving crocodile plate. The end of the
elbow plate away from the moving crocodile plate is rotatably connected to a mounting beam. At least one tie rod is rotatably mounted on the moving crocodile mounting body below the
elbow plate. The end of the tie rod away from the moving crocodile plate is connected to the mounting beam via a tension
assembly. Both ends of the mounting beam are slidably connected to the
machine body via sliding assemblies. In use, this utility model allows control of the drive
hydraulic cylinder to extend and retract, causing the drive
hydraulic cylinder to move the mounting beam towards or away from the stationary crocodile plate, thereby changing the distance between the moving and stationary crocodile plates, allowing the distance between the moving and stationary crocodile plates to be changed at any time.
