Cooling storage device for plastic particles

The cooling storage device comprises a storage box, supporting legs are vertically fixed to the two ends of the two sides of the bottom of the storage box respectively, an ejector rod is transversely fixed to the top end of the interior of the storage box, and suction openings are fixed to the two sides of the top end of the interior of the storage box respectively. Connecting pipes are fixed to the two sides of the top end of the storage box correspondingly. According to the cooling and storing device for the plastic particles, when the stored plastic particles are guided out of the device, after a discharging opening is opened, a second driving motor is controlled to start an output shaft, and a conveying shaft is driven to rotate in a bottom cavity through a belt wheel structure; the plastic particles in the storage box can be rapidly conveyed to the discharging opening through the rotating bottom cavity and can be guided out from the discharging opening, the blocking situation can be reduced in the discha
