Referring to fig. 1 to 8, the working process of the environment-friendly and green education platform of the embodiment is as follows:

the method comprises the following steps: the speed reducing motor 11 is started, an output shaft of the speed reducing motor 11 drives the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the two first chain wheels 14 to rotate, the two first chain wheels 14 drive the two second chain wheels 15 to rotate through the two chains, the two second chain wheels 15 drive the second rotating shaft 13 to rotate, the second rotating shaft 13 drives the two transmission discs 16 to rotate, the two transmission discs 16 are matched to drive the two circulating chains 6 to rotate along the two circulating tracks 5, the first connecting sheets 7 and the second connecting sheets 8 which are correspondingly arranged on the two circulating chains 6 circularly lift, and then the circulating tray 10 circularly lifts, and different types of propaganda materials are placed on different circulating trays 10 on the supporting frame 4 from the material storage port;

step two: when the education platform needs to be moved, the torque motor 29 is started, the output shaft of the torque motor 29 drives the belt pulley to rotate, the two belt pulleys coaxially drive the two first belt rollers 22 to rotate, the first belt rollers 22 are matched with the second belt rollers 23 to drive the first belt to rotate, the two second lifting plates 25 descend along the guide rods, the four trundles 27 lift the base 3, the education platform can be moved through the trundles 27, when the education platform needs to be fixed, the output shaft of the torque motor 29 reversely rotates, the two first lifting plates 24 descend along the guide rods, the two second lifting plates 25 ascend along the guide rods, the lifting legs 26 and the trundles 27 are retracted into the base 3, when the education platform needs to be lifted, the output shaft of the torque motor 29 continuously reversely rotates, and the four lifting legs 26 lift the education platform;

step three: when the teaching platform is used, the centrifugal fan 32 sucks outside air into the air treatment cavity 30 from the air inlet grille 36, the plasma generator 33 purifies the air, the heater 34 heats the purified air, the heated air is discharged from the air outlet 35, when garbage needs to be stored, the garbage is placed into the conveying pipeline 41 and enters the garbage conveying cavity 38 through the conveying pipeline 41, the conveying motor 40 drives the conveying screw rod 39 to rotate through an output shaft, the conveying screw rod 39 conveys the garbage and simultaneously crushes the garbage, and the crushed garbage is conveyed out of one end of the garbage conveying cavity 38 and falls into the garbage storage box 37 to be stored.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the following claims.
