Recently, Xugong excavator's three invention patents have been granted with authorization. They are a hydraulic drive device for excavators, an accelerator control method for electronic fuel injection diesel engines of excavators, and an excavator adjustable heat dissipation system. Among them, an excavator hydraulic drive device greatly increases the digging force of the excavator stick of the hydraulic excavator, which can reduce the fuel consumption and greatly increase the working efficiency; the method for controlling the throttle control device of an EFI diesel engine of an excavator can effectively reduce the fuel consumption while enabling The power of the diesel engine of the excavator is matched with the main pump power to achieve the best, reducing noise and significantly improving the smoothness of the operation; an excavator adjustable cooling system adjusts the relative position between the air conditioner condenser, the radiator and the fan to the maximum Good, maximize the radiator's cooling capacity. The invention patent is an important standard that reflects the company's scientific and technological development and innovation level. Up to now, Xugong excavator has successfully obtained 5 invention patents, and it is on the road to independent research and development.
