The invention provides a quick charging device for presplitting blasting of a deep hole roof, which is characterized in that at least two pushing rod seats for mounting filling rods are uniformly and detachably mounted on a stepless power transmission device, and the distance between two adjacent pushing rod seats is equal to the length of each filling rod; the distance between the first pushing rod seat and the filling locking device is slightly greater than the length of the filling rod; and each pushing rod seat can be cycled periodically along the front guide wheel and the rear guide wheel. The invention further provides a using method of the rapid charging device for deep hole roof presplitting blasting. When the filling rods are replaced and continuously pushed, the next filling rod can automatically reach the designated position, the next filling operation can be carried out only through slight adjustment, the operation efficiency is high, compared with an existing explosive filling device, it is not n
