Type of single bucket excavator:
according to different working devices, single bucket excavator can be divided into forward shovel, backhoe, dragline and grab shovel
1. The working characteristics of front shovel excavator are forward driving, forced cutting from bottom to top, large digging force and high proction efficiency; It is suitable for excavating class I to III soil with water content less than 27%, and cooperating with mp truck to complete the whole excavation and transportation operation; It can excavate large dry foundation pit and earth mound
when the bucket is placed on the parking surface to start digging, the bucket mouth faces outward (forward), which is suitable for digging the working surface above the parking surface. For the hydraulically operated front shovel excavator, it can dig the working surface below the parking surface
2. Backhoe excavator
when the bucket is placed on the parking surface and starts to dig, its bucket mouth faces inward (backward or downward). During the working process, the bucket rotates inward. It is suitable for digging the working surface below the parking surface, and for the hydraulically operated forward shovel excavator, it can dig the working surface above the parking surface
The bucket of dragline excavator is suspended and operated by steel cable. When the bucket is pulled to the fuselage for excavation, it is suitable for the working face below the machine face, and the mping method is throwing
4. The working device of grab (shovel) excavator is a kind of grab with double or multiple lobes. For mechanically operated excavators, it is suspended on the boom with lifting cables, and the opening and closing of the bucket lobes are realized by closed cables. There are also hydraulic grabs
according to the operation mode of the working device, it can be divided into mechanical cable operation mode; Mechanical hydraulic integrated type; Mechanical pneumatic integrated type; Full hydraulic pressure type
2. Tire type
it uses a special chassis with increased track width to increase its stability, and it can extend and retract hydraulic outriggers according to needs
However, its stability is relatively poor. Many small hydraulic excavators use this walking device. General municipal engineering units are used for excavation and routine maintenance of various urban pipeline ditches3. Car type
it runs faster than tire type, and others are similar to tire type
extended data:
single bucket excavator is widely used in construction, road construction, water conservancy, electric power, mining, oil, natural gas and national defense construction, and generally works with mp truck
The single bucket excavator is mainly a kind of earth moving machinery. In construction engineering, single bucket excavator can excavate foundation pit, trench, clean and level the site. It is a very important mechanical equipment in the earthwork construction of construction engineering. After replacing the working device, it can also carry out crushing, loading and unloading, lifting, piling and other tasksthe power devices of single bucket excavator include diesel engine drive, electric drive (called electric shovel), steam engine drive and compound drive. Its transmission includes mechanical transmission and hydraulic transmission
There are crawler type, tire type, track type, walking type and floating type. The turntable can be used for 360 ° Full rotation or partial rotation. In civil engineering construction, diesel driven, rotary and hydraulic excavators are commonly usedthe bucket of front shovel excavator is hinged at the end of the stick and supported by the boom. Its digging action is from bottom to top, and the track of the bucket tooth tip is often in an arc, which is suitable for excavating the soil above the parking surface. The bucket of backhoe excavator is also hinged with the stick. Its digging action is usually from top to bottom, and the bucket tooth track is in arc, which is suitable for digging the soil below the parking surface. The bucket of the planer excavator moves along the lower edge of the boom. When the boom is placed in a fixed position, the path of the bucket tooth tip is in a straight line, so a flat excavation surface can be obtained, which is suitable for slope excavation, side ditch excavation or site leveling. The bucket of dragline excavator is in the shape of stpan, and the front edge of bucket bottom is equipped with bucket teeth. When working, the bucket is thrown outward on the excavation surface, the bucket teeth are cut into the soil again by the bucket, and then the bucket is pulled by the traction cable to dig the soil. After the digging is full, the bucket is lifted by the lifting cable, the turntable turns to the unloading point, and the bucket turns over to unload the soil. It can excavate the soil below the parking surface, and it can also excavate underwater. The excavation range is large, but the excavation accuracy is poor. The bucket of grab shovel is hinged by two or more jaw flaps. When the jaw flap is open, the blade of the flap cuts into the soil, and the steel cable or hydraulic cylinder is used to collect the jaw flap to dig and grasp the soil. Release the jaw flap to unload the soil. It is used for foundation pit or underwater excavation with large excavation depth. It can also be used for loading granular materials. The working device of medium and small excavators commonly used in earthwork can be removed and replaced, and different buckets can be installed for different operations. It can also be refitted into crane, pile driver, rammer, etc., so it is called universal (multi-functional) excavator. Mining or mining excavators are generally equipped with only one working device for single operation, so they are called special excavators
according to the walking mode, it can be divided into crawler type and tire type,
according to the transmission mode, there are mechanical transmission and hydraulic transmission
single bucket excavator with hydraulic transmission
excavator that uses oil pump, hydraulic cylinder, hydraulic motor and other components to transmit power. The pressure oil output by the oil pump pushes the hydraulic cylinder or motor to work respectively to make the corresponding parts of the machine run. Backhoe excavator is common (see color picture). During backhoe operation, the boom is lowered as a support, and the bucket is placed below the stop surface by the stick hydraulic cylinder or bucket hydraulic cylinder, which makes the bucket move in an arc to excavate and load soil. Then the boom is lifted, and the rotary motor is used to turn to the unloading point, and the bucket is turned over to unload soil. The whole machine is driven by left and right hydraulic motors, and the motor can move forward, backward or turn. Tire travel is also driven by the engine through the gearbox, main drive shaft and differential, but the mechanism is complex. Small and medium-sized machines are driven by two pumps, and some of them are driven by a single pump to save power. The main technical parameters of hydraulic excavators are bucket capacity, and also machine weight or engine power. This kind of excavator is compact in structure, light in weight, and often has a variety of changeable working devices to meet the needs of various operations. It is light and flexible in operation, stable and reliable in work, so it has developed rapidly and has become the main variety of excavators.
