Recycled concrete crushing and screening device with efficient crushing function

The recycled concrete crushing and screening device comprises a mounting frame, an operation table is fixedly mounted on the mounting frame, a crushing assembly used for crushing concrete and a screening assembly used for screening the crushed concrete are arranged on the operation table, and the screening assembly comprises a screening plate which is obliquely arranged; the vibrating assembly is located on one side of the screening plate, the vibrating assembly can be driven to synchronously operate when the crushing assembly operates, a circulating assembly used for circularly crushing the concrete disintegrating slag is further installed on one side of the installation frame, and the circulating assembly corresponds to the crushing assembly and the screening assembly in position. Compared with the prior art, the crushing effect on concrete is improved, the screening effect can be improved, unqualified concrete particles can be promoted to enter the circulating box, and the secondary crushing efficiency of
