The present embodiment comprises a fixed support plate 3 arranged on the crusher 1 at the end of the roller 2, a support plate fixing device 4 being arranged between the fixed support plate 3 and the crusher 1. The supporting plate fixing device 4 comprises a supporting rod 41 fixedly arranged on the side wall of the end part of the roller 2 on the crusher 1, a supporting protrusion 42 is arranged at one end of the supporting rod 41 extending to the roller 2, and a supporting clamping seat 43 corresponding to the supporting protrusion 42 is arranged on the fixed supporting plate 3. In this embodiment, the supporting protrusion 42 is a circular protrusion, the supporting clamping seat 43 is welded on the fixed supporting plate 3, the supporting clamping seat 43 is provided with an end clamping groove with a downward opening corresponding to the supporting protrusion 42, an outer plate of the end clamping groove is provided with a U-shaped or V-shaped rod clamping groove with a downward opening corresponding to the rod portion of the supporting rod 41, and the structure of the supporting clamping seat 43 can be easily obtained by a person skilled in the art according to knowledge and experience, and is not described herein. In this embodiment, the support rods 41 are arranged in an isosceles triangle, when the fixing support plate 3 is installed, only the rod portions of the support rods 41 and the U-shaped rod portion clamping grooves on the support clamping seat 43 need to be aligned downwards, the support protrusions 42 are clamped into the end portion clamping grooves, and the stability of the fixing support plate 3 after installation can be ensured by the three support rods 41 in the isosceles triangle.
An end leakage gap 8 is formed between the fixed support plate 3 and the end surface of the roller 2, that is, in this embodiment, compared with the leakage-proof plate in the prior art, the fixed support plate 3 is separated from the end surface of the roller 2 by a certain distance, and a gap formed by separating the fixed support plate 3 from the end surface of the roller 2 is the end leakage gap 8 in this embodiment.
A brush leakage-proof device is arranged on the fixed supporting plate 3 at the inlet corresponding to the end leakage gap 8, the brush leakage-proof device comprises a leakage-proof brush belt 6 arranged at the inlet of the end leakage gap 8, and the free ends of bristles of the leakage-proof brush belt 6 are abutted against the end part of the roller 2; the leak-proof hairbrush belt 6 of this embodiment completely blocks the end leakage gap 8, compared with the leak-proof plate of the prior art, the leak-proof hairbrush belt 6 is in flexible contact with the end face of the roller 2, because the roller 2 has low rotation speed during operation, the leak-proof hairbrush belt 6 in flexible contact is worn slightly, so that the service life of this embodiment can be prolonged, and meanwhile, the flexible leak-proof hairbrush belt 6 can adapt to the axial extension of the roller 2 after thermal expansion, so that the structural damage and the other clamping phenomenon caused by the thermal expansion of the roller 2 are avoided. The anti-leakage hairbrush belt 6 is fixedly arranged on the fixed supporting plate 3 by means of screws 63, and hairbrush mounting holes corresponding to the screws 63 are formed in the fixed supporting plate 3.
