  Further, according to the present embodiment, the movable hopper frame 22, the movable hopper 50, and the hydraulic cylinders 30R and 30L form a closed loop. The forces generated in the movable hopper brackets 23R, 23L and the hydraulic cylinder brackets 24R, 24L during the hydraulic relief of the hydraulic cylinders 30R, 30L act on the movable hopper frame 22. That is, the structure can be simplified because the single movable hopper frame 22 has to have sufficient strength.

  Further, according to the present embodiment, the movable hopper frame 22 that supports the movable hopper 50 and the hydraulic cylinders 30 </ b> R and 30 </ b> L is detachable from the crusher 5. The movable hopper frame 22, the movable hopper 5, and the hydraulic cylinders 30R and 30L are integrated. That is, the movable hopper 50 and the hydraulic cylinders 30R, 30L are attached / detached only by attaching / detaching the movable hopper frame 22 to / from the crusher 5. The attachment / detachment of the movable hopper frame 22 is a simple operation such as attachment / detachment of bolts. Accordingly, the movable hopper 50 and the hydraulic cylinders 30R and 30L can be easily attached to and detached from the crusher 5.

  Further, according to the present embodiment, there is no gap between the fixed hopper 40 and the movable hopper 50 due to the presence of the sheets 58R and 58L. Therefore, when the movable hopper 50 is inclined, the spilled material from the side walls of the movable hopper 50 and the fixed hopper 40 is reduced.

  The hydraulic cylinder brackets 24R and 24L may not be provided in the frame portion 20. For example, as shown in FIG. 9, hydraulic cylinder brackets 64 </ b> R and 64 </ b> L may be directly fixed to the front wall surface of the crusher 5. However, according to such an embodiment, reinforcement is required around the hydraulic cylinder brackets 64R and 64L.

  Further, the movable hopper 50 may not be arranged in the direction opposite to the engine room 2. For example, even if the movable hopper is arranged in the front or left / right direction, the effect of facilitating the operation of attaching / detaching the movable hopper can be obtained as long as the hydraulic cylinder bracket is fixed to the crusher.
