When adjusting conveyer belt one end height, the inclination of conveyer belt changes, still need the distance between two elevating gear of artifical synchronous change, be about to an elevating gear level and move, so that elevating gear keeps vertical state, avoid elevating gear to empty, this also can only rotate the reason that changes the conveyer belt tip height with the manual drive hand wheel on the current elevating gear, if directly rotate through motor drive screw, conveyer belt inclination changes, elevating gear's lower extreme and ground are connected and are kept motionless, horizontal motion takes place along with the slope of conveyer belt in the upper end, elevating gear will unable vertical state of keeping, empty easily and lead to the conveyer belt to damage. Because the conveyer belt that uses in the grit mining field is bulky, weight is heavy, and the hand wheel rotation can be more laborious, and slew velocity is slow, leads to elevating gear's governing speed to be slow. Therefore, the existing lifting device has the defects of labor-consuming adjustment and slow adjustment speed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a motor-driven elevating gear of conveyer belt. The utility model has the advantages of labor saving and fast adjusting speed.
