excavators structure

excavators are composed of bucket, bucket column, slewing arm, supporting foot or supporting wheel and hydraulic system (see Figure). The bucket is hinged with the bucket column, which is hinged at the end of the swing arm. The hydraulic system controls the lifting of the slewing arm and the rotation in the horizontal plane, the rotation of the bucket column in the vertical plane, the lifting of the supporting feet, and the change of the digging, lifting and unloading state of the bucket through each special oil cylinder, so that the bucket can excavate the earthwork 3-4 meters above and below the ground, and unload the soil to the designated position

the capacity of excavator bucket is about 0.1m3 per 15kw according to the power of matching tractor. After unloading the bucket, it can also be equipped with clam grab, multi tooth grab parts or lifting hook and other working parts, which can be used for material loading, lifting, loading and unloading and other operations (from China excavator website)

Maintenance

the purpose of regular maintenance of excavators is to rece machine failures, prolong machine service life, shorten machine downtime, improve work efficiency and rece operating costs [4]

as long as the fuel, lubricating oil, water and air are well managed, the faults can be reced by 70%. In fact, about 70% of the failures are caused by poor management

daily inspection

visual inspection: visual inspection shall be concted before starting the locomotive. Thoroughly check the surrounding environment and the bottom of the locomotive in the following order:

1. Whether there are oil, fuel and coolant leaks

Whether there are loose bolts and nuts

3. Whether there are broken wires, short circuits and loose battery connectors in the electrical circuit

Daily inspection is an important link to ensure that hydraulic excavators can maintain efficient operation for a long time, especially for the self-employed, daily inspection can effectively rece maintenance costs
first, rotate the machine twice to check whether the appearance and chassis are abnormal, and whether there is grease flowing out of the slewing bearing. Then, check the deceleration brake device and the bolt fasteners of the track. If it is a wheeled excavator, it is necessary to check whether the tires are abnormal, and the stability of the air pressure
check whether the bucket teeth of excavators have large wear. It is understood that the wear of bucket teeth will greatly increase the resistance in the construction process, seriously affect the work efficiency and increase the wear degree of equipment parts
check the stick and cylinder for cracks or oil leakage. Check the battery electrolyte to avoid being below the low level line
air filter is an important part to prevent a large amount of sty air from entering the excavator, and it should be checked and cleaned frequently
always check whether the fuel, lubricating oil, hydraulic oil, coolant, etc. need to be added, and it is best to select the oil according to the requirements of the manual and keep it clean

After starting, check whether

1, whistle and all instruments are in good condition

2, engine starting state, noise and exhaust color

Whether there is oil, fuel and coolant leakage

fuel management

different brands of diesel should be selected according to different ambient temperatures (see Table 1 for details); Diesel oil should not be mixed with impurities, lime soil and water, otherwise the fuel pump will be worn prematurely; The content of paraffin and sulfur in inferior fuel is high, which will damage the engine; After daily operation, the fuel tank should be filled with fuel to prevent water droplets on the inner wall of the tank; Open the drain valve at the bottom of the fuel tank to drain water before daily operation; Exhaust the air in the pipeline after the engine runs out of fuel or the filter element is replaced

minimum ambient temperature 0 ℃ - 10 ℃ - 20 ℃ - 30 ℃

diesel grade 0 # - 10 # - 20 # - 35#
