[0041] Second embodiment

[0042] Please refer to Figure 4 , Figure 5 and Figure 6Based on the crushing mechanism for waste concrete recycling provided by the first embodiment of the present application, the second embodiment of the present application proposes another crushing mechanism for waste concrete recycling. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0043] Specifically, the second embodiment of the present application provides a crushing mechanism for recycling waste concrete. The difference is that, in a crushing mechanism for recycling waste concrete, a connecting device 17 is sleeved on one side of the outer surface of the limit block 83, and the connecting device 17 includes a connecting sleeve 171. A setting hole 172 is opened in the middle of one side of the connecting sleeve 171, and movable grooves 173 are opened on both sides of the inner cavity wall of the setting hole 172. A sliding rod 174 is fixedly installed inside the movable groove 173, and a spring 175 is sleeved on one side of the outer surface of the sliding rod 174, and limiting rods 176 are fixedly installed on both sides of the outer surface of the connecting sleeve 171.
