Automatic oil spraying device for transmission chain of chain conveyor in low-temperature environment

The utility model belongs to the technical field of lubrication, and particularly relates to an automatic oil spraying device for a transmission chain of a chain conveyor in a low-temperature environment. Comprising an oil storage tank with a cylindrical upper portion and a conical lower portion, a heating device is installed at the cylindrical bottom of the oil storage tank, a temperature detection device is installed in the middle of the oil storage tank, an electromagnetic valve is connected to the top of a cone of the oil storage tank, and control signals of the electromagnetic valve, the heating device and the temperature detection device are connected into a PLC. Lubricating oil in the air storage tank can be kept in the temperature interval with the optimal flowing property by arranging the heater. Control signals of the electromagnetic valve, the temperature detection device and the heating device are input into a PLC to control an oil spraying switch, and the lubricating time and the lubricating oil
