[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 A noise-reducing crusher wear-resistant tooth plate comprises a frame 1 for loading and supporting and a fixed tooth plate body 7.

[0026] Among them, the fixed tooth plate body 7 is a high manganese steel wear-resistant tooth plate. The wear-resistant tooth plate made of high manganese steel has excellent wear resistance and can effectively resist wear and avoid damage even when used for a long time.

[0027] In addition, in order to achieve the purpose of effective shock absorption, a noise reduction processing component for shock absorption and noise reduction is fixedly connected to the upper surface of the frame 1, and the top of the noise reduction processing component is fixedly connected to the fixed tooth plate body 7.

[0028] Among them, the noise reduction processing component includes a sound insulation pad 2, the top of the sound insulation pad 2 is fixedly connected with a shock force processing chamber 3, the inner bottom wall of the shock force processing chamber 3 is fixedly connected with a plurality of damping shock absorbers 4, the top of the damping shock absorber 4 is fixedly connected with a shock-conducting steel plate 5, the top of the shock-conducting steel plate 5 is fixedly connected with a plurality of shock-conducting steel rods 6, and the top of the shock-conducting steel rods 6 is fixedly connected to the fixed tooth plate body 7. By arranging the shock-conducting steel rods 6 and the shock-conducting steel plates 5, the vibration force can be effectively absorbed, and the arranged damping shock absorbers 4 can also effectively eliminate the conducted resonance. In this embodiment, a sound insulation pad 2 is also arranged, which can further absorb and alleviate the remaining noise.

[0029] It should be noted that in the above embodiment, the number of the damping shock absorbers 4 is thirty groups, the number of the damping shock absorbers 4 in each group is eight, and the damping shock absorbers 4 in each group are evenly and equidistantly distributed.

[0030] In addition, in order to further improve the noise reduction capability, an outer sleeve 8 is evenly fixedly connected to the four corners of the upper surface of the frame 1, and an elastic support component with one end extending to the outside of the outer sleeve 8 is fixedly connected inside the outer sleeve 8 for deformable support processing, and the top of the elastic support component is fixedly connected to the fixed tooth plate body 7.

[0031] Among them, the elastic support component includes an elastic deformation column 9, the bottom of the elastic deformation column 9 is fixedly connected to the inner bottom wall of the outer sleeve 8, the top of the elastic deformation column 9 is fixedly connected to a plug rod 10 with one end extending to the outside of the outer sleeve 8, the outer wall of the plug rod 10 is in active contact with the outer sleeve 8, and the top of the plug rod 10 is fixedly connected to an elastic gasket 11, and the top of the elastic gasket 11 is fixedly connected to the fixed tooth plate body 7. By setting the elastic support component, the overall fixed tooth plate can have a slight deformation ability after being impacted, thereby further improving the shock absorption and noise reduction function.

[0032] It should be noted that in the above embodiment, the elastic gasket 11 is at least one of a rubber gasket, a polyurethane gasket, and a foam plastic gasket. Therefore, the elastic gasket 11 has a certain elastic performance and can better enhance the elastic capacity of the structure during deformation.

[0033] The working principle of this embodiment is as follows:

[0034] When the fixed tooth plate body 7 is performing the crushing process with the movable tooth plate, the vibration caused by the impact on the fixed tooth plate body 7 can be transmitted to the shock-guided steel plate 5 through the shock-guided steel rod 6 for dispersion and absorption, and the resonance generated after dispersion and absorption is dissipated by the damping shock absorber 4, and finally the remaining noise is effectively absorbed by the sound insulation pad 2. By arranging the plug rod 10 and the elastic deformation column 9 as auxiliary support parts, a small amount of deformation ability can be generated when impacted, thereby avoiding part of the rigid conduction, converting the original rigid conduction into elastic conduction, further improving the shock-absorbing and noise reduction ability, and achieving the purpose of effective noise reduction as a whole.
