Waste rubber material recycling and crushing device

The invention relates to a waste rubber material recycling and crushing device which comprises a crushing box, a screening mechanism capable of screening rubber materials is arranged at the top of the crushing box, and the screening mechanism comprises a first conveying assembly, a second conveying assembly and a third conveying assembly. The first conveying assembly, the second conveying assembly and the third conveying assembly are integrally in a V shape, the conveying speeds of the first conveying assembly, the second conveying assembly and the third conveying assembly are different, and crushing rollers for crushing rubber materials are symmetrically arranged in the crushing box. The problem that in the prior art, although the rubber materials can be crushed unevenly, due to the fact that waste rubber materials needing to be crushed are often inconsistent in size and are not screened before crushing, the rubber materials of different specifications are prone to interfering with one another, the crushing
