The invention discloses an oiling machine automatic calibration device with a fast oil return function. The oiling machine automatic calibration device comprises a control valve, an oil conveying tube, a control panel and an oil observation device. The oil observation device is installed on the upper portion of the right side of a device shell. The control valve is installed on an oil outlet tube. An explosion-proof storage battery is arranged at the position, close to the lower portion of the left side of the oil outlet tube, in the device shell. An oiling machine sensor is arranged at the position, close to the left side of the oil observation device, in the device shell. A static neutralizer is arranged on the right side of a humidity sensor. A pulse signal is subjected to analysis in the control panel, so that metering calibration and control of the oil quantity are achieved; an oil inlet explosion-proof oil pump can be used for pumping out fuel oil from an external oil tank and supplementing an oil box with the fuel oil; the humidity sensor is arranged on the shell of an oiling machine and can be used for detecting the humidity in external air, and when the air is dry, the air humidity can be increased through watering; and the static neutralizer is arranged on the oiling machine, so that safety accidents caused by static can be prevented.
