The invention discloses a smashing device for carotene extraction teaching. The smashing device for carotene extraction teaching comprises a shell. A horizontal partition plate is fixedly connected into the shell. A motor installation seat is fixedly connected with the left side of the lower side of the horizontal partition plate. A motor is fixedly connected with upper side of the motor installation seat. The output end of the motor is fixedly connected with a driving bevel gear. A longitudinal rotating shaft is rotationally connected with the middle portion of the horizontal partition plate.The lower end of the longitudinal rotating shaft is fixedly connected with a driven bevel gear. The driven bevel gear is meshed with a driving bevel gear. A rotating disk is fixedly connected with the upper side of the longitudinal rotating shaft. The outer side of the upper side of the rotating disk is fixedly connected with a rotating support column. A cutting blade is fixedly connected with the upper side of the rotating support column. The outer side of the rotating disk is evenly provided with a plurality of guide grooves. Compared with the prior art, the smashing device for carotene extraction teaching has the beneficial effects of being simple in structure, convenient to use and capable of more sufficiently smashing carrots into paste and more sufficiently extracting carotene and achieving a better teaching effect.
