Vertical moving device of spraying pipes on barrel washing machine

The invention discloses a vertical moving device of spraying pipes on a barrel washing machine, wherein the vertical moving device can synchronously rise or fall. The vertical moving device comprises a plurality of the spraying pipes with spray heads, the spraying pipes are installed on a spraying pipe support, the two ends of the spraying pipe support are respectively and vertically provided with two lifting rods, the upper end of each lifting rod penetrates through a guide hole in an installation frame and then is hinged to the lower end of a connection rod in a corresponding crank sliding block mechanism, a crank in each crank sliding block mechanism is connected with a corresponding rotary shaft and is driven to rotate through the corresponding rotary shaft, the two rotary shafts located on the same side are connected with two output shafts of a speed reducer on the same side respectively, input shafts of the two speed reducers on the two sides are connected with two output shafts of a speed reduction motor respectively, the speed reduction motor and the two speed reducers are installed on the installation frame, the speed reduction motor drives the rotary shafts to rotate through the two speed reducers, and accordingly the crank sliding block mechanisms are driven to drive the lifting rods to synchronously and vertically move upwards or downwards.
