It should be particularly and clearly stated that, in order to more clearly and clearly illustrate the present invention, as a preferred embodiment, the present invention is configured such that when the crushing body is pressed, the bottom plate 233 is located at the lower end of the box 231 and separates the inner cavity from the outer cavity of the box 231, and the lower portion of the bottom plate 233 has the supporting frame 1 abutted thereto, so that when the pressing plate 234 is pressed downward, the bottom plate 233 can generate a sufficient reaction force, and thus the body to be crushed can be completely crushed.
Through the scheme, the technology for manufacturing the construction waste into the recycled aggregate for the highway backfill layer is realized.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
