[0030] Reference Figures 1 to 5 The embodiment of the present application provides a fastening device for a crusher hammer, comprising a crusher housing 1, wherein a protective assembly 4 is provided inside the crusher housing 1, wherein the protective assembly 4 comprises a protective shell 41, wherein the upper and lower top walls of the protective shell 41 are fixedly connected to support sleeves 47, wherein the inner bottom wall of the support sleeve 47 is fixedly connected to a spring 46, wherein the top end of the spring 46 is fixedly connected to a connecting block 45, wherein the top end of the connecting block 45 is rotatably connected to a support rod 44 via a rotating shaft, wherein the middle portion of the side wall of the protective shell 41 is fixedly connected to the support sleeve 47, wherein the upper and lower top walls of the protective shell 41 are fixedly connected to a support sleeve 47, wherein the inner bottom wall of the support sleeve 47 is fixedly connected to a spring 46, wherein the top end of the spring 46 is fixedly connected to a connecting block 45, wherein the top end of the connecting block 45 is rotatably connected to a support rod 44 via a rotating shaft, wherein the middle portion of the side wall of the protective shell 41 is fixedly connected to the support sleeve 47, wherein the upper and lower top walls of the protective shell 41 are ... A support block 42 is fixedly connected, a strip groove is opened in the middle of the support block 42, and the lower end of the support rod 44 is rotatably connected to the strip groove of the support block 42 through a rotating shaft; a damper 43 is fixedly connected between the support blocks 42, and the side wall of the protective shell 41 is movably connected to the side of the protective shell 41, and the upper and lower surfaces of the side wall of the protective shell 41 are fitted with the upper and lower bottom walls of the protective shell 41; a feed port 2 is provided at the top of the grinder casing 1, and a discharge port 3 is provided at the bottom of the grinder casing 1.

[0031] In this embodiment, all devices are based on the crusher casing 1. When the device is in use, feeding is carried out from the feed port 2, and the inside of the crusher casing 1 is protected by the protective component 4. The first structure in the protective component 4 to be hit by foreign objects is the side wall of the protective shell 41. When the side wall of the protective shell 41 is hit, it will slide from the outside to the inside along the upper and lower top walls of the protective shell 41. When the side wall of the protective shell 41 slides, it drives the support block 42 on its surface to displace, thereby compressing the damper 43. The reaction force of the damper 43 buffers the force generated by the impact of foreign objects. When the support block 42 moves, it will drive the support rod 44, the connecting block 45, and the spring 46 to move synchronously. After being squeezed, the spring 46 retracts and contracts inside the support sleeve 47, and also releases the collision force on the side wall of the protective shell 41, thereby achieving the purpose of protecting the inside of the crusher casing 1 through the protective component 4.
