In the invention, a locking mechanism is used for locking a material receiving groove 12 on a first crushing shell 5 at the beginning, a release spring 20 is in a compression state at the moment, when a hard material is clamped between a movable jaw 2 and a static jaw 3, a first air cylinder 14 drives the first crushing shell 5 to move towards the direction far away from the static jaw 3, the locking mechanism releases the material receiving groove 12 at the moment, the material receiving groove 12 is bounced away from the first crushing shell 5 under the action of the release spring 20 and moves to the lower part of a crushing cavity 8 so as to collect the hard material falling from the space between the movable jaw 2 and the static jaw 3; then the first air cylinder 14 drives the first crushing shell 5 to move towards the direction close to the static jaw 3, the release spring 20 is gradually compressed, and the locking mechanism locks the collecting trough 12 after the collecting trough 12 is reset.

Specifically, the locking structure comprises a placing cylinder 21, the placing cylinder 21 is arranged on the crushing frame 1, a first piston 22 is arranged in the placing cylinder 21, and the first piston 22 is sealed in the placing cylinder 21 in a sliding manner; one end of the push-pull rod 23 is mounted on the first crushing frame 5, and the other end of the push-pull rod 23 extends into the placing cylinder 21 and is connected to the first piston 22; one end of the communicating pipe 24 is communicated with the placing barrel 21, the other end of the communicating pipe 24 penetrates through the first crushing shell 5 and extends into the first crushing shell 5, a second piston 25 is installed in the communicating pipe 24, and the second piston 25 is sealed in the communicating pipe 24 in a sliding mode; a connecting block 26, one end of the connecting block 26 being connected to the second piston 25; the middle part of the fixture block 27 is rotatably mounted on the first crushing shell 5, the fixture block 27 is further connected to the first crushing shell 5 through a tension spring 28, and one end part of the fixture block 27 is in sliding fit with the other end part of the connecting block 26; and the hook 29 is arranged on the material receiving groove 12, and the hook 29 can be hooked on the other end of the clamping block 27. In the invention, when the first air cylinder 14 drives the first crushing shell 5 to move in the direction away from the static jaw 3, the push-pull rod 23 pushes the first piston 22 and the second piston 25 one by one, then the connecting block 26 moves under the action of the second piston 25 and pushes the clamping block 27 upwards by utilizing the inclined surfaces matched with the connecting block 26 and the clamping block 27 in a sliding way, and the clamping block 27 rotates and releases the hook 29, thereby releasing the collecting groove 12.
