Fuel set filter device in construction mechanical fuel tank

The utility model relates to a fuel set filter device in a construction mechanical fuel tank, which is characterized by comprising a connection tray, an oil pipe, a metal net filter element joint and a metal net filter element, wherein the connection tray is connected with the fuel tank, the oil pipe is mounted in the center hole of the connection tray in a penetrating way, the lower end of the oil pipe is connected with the metal net filter element joint, and the lower end of the metal net filter element joint is connected with the metal net filter element. Before the fuel enters an oil supply system, impurities and foreign bodies in the fuel are filtered through the metal net filter element joint, so that an oil inlet can not be blocked by larger foreign bodies, and the clean fuel oil enters the fuel oil low pressure pump and the precision filter of an engine through the oil pipe, thereby improving the clean level of the mechanical fuel, and prolonging the service life and the reliability of the precision p
