Multi-level finished product crushing screening machine

The invention discloses a multi-level finished product crushing screening machine which comprises a discharge mechanism and a screening mechanism. The discharge mechanism comprises a discharge hopper and a discharge hopper fixing frame, a discharge outlet is formed in the bottom of the discharge hopper, a discharge switch is arranged at the discharge outlet, and the screening mechanism is arranged below the discharge hopper and comprises a primary screening device, a secondary screening device, a power device and a fixing device; when the multi-level finished product crushing screening machine is used, crushed granules of finished products drop into a primary filter sieve via the discharge outlet, and crushed granules which pass the primary filter sieve are fed into a secondary filter sieve; a secondary filter mechanism is suspended, is connected with an eccentric wheel and accordingly can move. The multi-level finished product crushing screening machine has the advantages that screening power can be provided by the power device, and accordingly the multi-level finished product crushing screening machine is high in efficiency; the granules with three levels of sizes can be separated from one another by the aid of the multi-level finished product crushing screening machine with the simple structure, good screening effects can be realized, the multi-level finished product crushing screening machine is low in equipment maintenance cost and convenient to operate, and popularization and application of the multi-level finished product crushing screening machine to industries can be facilitated.
