The application discloses a process for improving the performance of a excavator and relates to the technical field of excavators. The process comprises the following steps: step S01, starting the engine and making it run at full throttle after preheating and performing digging, soil throwing, walking and lifting operations, detecting and recording the bucket digging force, bucket rod digging force, lifting force and traction force; and step S02, installing a hydraulic system tester on the high-pressure pipeline of the hydraulic pump of a new excavator by using a bypass method, making the pump run at a rated speed, and observing and recording the flow readings of the front and rear pumps of the tester when the hydraulic oil temperature is 50+ / -5 DEG C. The application is a process technology for adjusting the pressure of each working oil cylinder of the main control valve in the hydraulic system of a new or old excavator and the excellent matching of the pump and the engine, fully improves the fuel utilization rate of the engine and the working efficiency and benefit of the whole machine, saves energy and is economical, and can improve and repair the performance and quality of the new or old excavator, such as the digging, crushing, lifting moment and speed.

The application relates to the technical field of aggregate processing equipment, in particular to a crushing device for aggregate production, which comprises a hopper, a crushing cone and a rolling mortar wall, a crushing disc extending between the crushing cone and the rolling mortar wall is arranged at the position close to the hammer head of the hopper, the crushing disc is arranged at one end of the crushing cone close to the hopper, the crushing disc comprises a central ball and a cross rod, an end of the cross rod away from the central ball is provided with a crushing rod extending between the crushing cone and the rolling mortar wall, the cross rod is arranged around the central ball and extends to the outside of the cover body, the cross rod is provided with a plurality of cross rods which are uniformly arranged in the horizontal direction of the central ball, and a sealing mechanism for preventing dust from entering the placing bin is arranged on the cover body, the working surface formed between the crushing cone and the rolling mortar wall during the swing movement of the crushing cone is small, and the crushing efficiency is low, the problems are solved, and the application has good application in aggregate processing manufacturers.
