▎ 摘　　要

NOVELTY - The device has a substrate (1) whose upper side is fixed with two first hydraulic push rods (9) that are located at a side of two first fixing columns (2). An output end of the four hydraulic push rod are fixed with a second fixing block (9). An upper side of the two second fixing blocks is connected with a supporting plate (10) that is provided with a material arranging mechanism. An inner side of a first elliptical fixing block is fixed at two ends of two fixing rods. A buffer mechanism is provided between the two first fixed columns and two second fixed columns (31). The four vibration mechanisms are provided on an upper side surface of the substrate. Four vibration mechanisms correspond to the four first circular fixing blocks. A lower side of substrate is formed with four supporting mechanisms. USE - Graphene crushing and screening device. ADVANTAGE - The device is convenient to adjust the inclined angle of the supporting plate under the action of the four first hydraulic push rod, so as to control the speed of graphene raw material from the support plate. The distance between the two first rotating rollers is conveniently adjusted by the effect of two first electric push rods to conveniently control the size of the graphene particles after crushing. The damage of the hard particles in the crushing process to the first rotating roller is reduced. The two buffers in the second groove are convenient to buffer the sieve plate to reduce the abrasion of the sieves plate in the using process. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a graphene crushing and screening device. 1Substrate 2First fixing column 9Second fixing block 10Supporting plate 11First side plate 17Fixing plate 18Second side plate 19Second rotating roller 23Sieve plate 31Second fixed column 33Third hydraulic push rod
