The invention relates to a graphite powder collecting device, in particular to a convenient graphite powder collecting device, and aims to provide the graphite powder collecting device which is capable of collecting graphite powder conveniently, carrying out a multi-stage crushing treatment and saving manpower. The convenient graphite powder collecting device comprises a box body and the like, wherein a first baffle plate is rotationally connected to the bottom end of the right side of the box body, and the left side of the bottom of the first baffle plate is fixed at the bottom end of the left side of the box body in a bolt connection mode; a screen plate is connected to the upper part of the inner side of the box body, and first small holes are uniformly formed in the screen plate; and adriving mechanism is arranged on the lower part of the left side of the box body, a crushing mechanism is arranged at the upper part in the box body, and the crushing mechanism is connected with thedriving mechanism. According to the convenient graphite powder collecting device, the driving mechanism and the crushing mechanism are arranged, and therefore graphite can be crushed to obtain the graphite powder; and a motor is controlled to do continuous clockwise and anticlockwise alternate rotation motion.
