The invention discloses an efficient mixing device for plastic particles. The efficient mixing device comprises a bottom plate, a right side plate, a front side plate, a back side plate, a collectingframe, a mixing drum, bearing blocks, a supporting shaft, a mounting plate, a first motor, a rotating shaft, a disk, a first connecting rod, a second connecting rod, a transverse plate, a dischargingopening, a second motor, a stirring shaft, transverse stirring rods, stirring
branch rods, bevel gears and annular inclined racks. According to the efficient mixing device, the second motor, the stirring shaft, the transverse stirring rods, the bevel gears and the annular inclined racks are arranged and cooperate with one another, the transverse stirring rods drive the stirring
branch rods to rotate, stirring is performed by the transverse stirring rods and the stirring
branch rods together, multiple stirring manners are provided, and the stirring and mixing efficiency is improved; the first motor, the disk, the first connecting rod, the second connecting rod, the transverse plate and the supporting shaft are arranged and cooperate with one another, the mixing drum shake leftwards and rightwards continuously, and the stirring and mixing efficiency is further improved; and a spiral pushing blade is arranged, during discharging, the plastic particles are pushed downwards, and blockage ofthe discharging opening is avoided.
