The utility model relates to a mine underground transportation and the industry technical field that prevents dust especially relates to a sticky tape transports machine and spraying dust device thereof for the solution can not open and close by oneself that the process that the switching caused is extravagant, the dust fall is untimely and water waste's problem along with what the sticky tape transported the machine because of spraying dust device. Spraying dust device includes coordinated control system, the sticky tape transports the press packed bale and draws together the sticky tape and transport quick -witted body more than and spraying dust device. Transport through coordinated control system and sticky tape and realize that spraying dust device transports opening and close of machine along with the sticky tape being connected of quick -witted switch and automatic switching, also avoided the process waste when the sticky tape transports that the machine is in service to have guaranteed good dust suppression effect, practiced thrift the water resource.
