Solid waste resource recycling and screening device

The invention relates to the field of solid screening devices, in particular to a solid waste resource recycling screening device.The solid waste resource recycling screening device comprises multiple stages of screening assemblies, particles sequentially pass through a first screening plate, a second screening plate and a third screening plate, and first screening holes in the first screening plate and third screening holes in the third screening plate are the same in aperture, so that the particle screening accuracy is improved; and after being screened by the third screening plate, the particles which do not enter the first guide plate and the third guide plate enter the next-stage screening assembly to be screened through the discharging opening of the shell and transmission of the transmission belt. When the first sieve plate is blocked, a first guide plate connected through a first elastic piece moves upwards by a certain distance, a third guide plate connected through a second elastic piece moves downw
