Home depot mini excavator operation method:
1. Home depot mini excavator walking device
The home depot mini excavator traveling device is the chassis, including the crawler frame and the traveling system, mainly composed of the crawler frame, traveling motor + reducer and its pipeline, driving wheel, guide wheel, sprocket, supporting wheel, crawler, tension buffer It is composed of a device whose function is to support the weight of the home depot mini excavator and convert the power transmitted by the driving wheels into traction to realize the walking of the whole machine.

The frame assembly (ie the crawler walking frame assembly) is an integral welded part and adopts an X-shaped structure. Its main advantage is that it has a high load-bearing capacity. The frame assembly consists of the left longitudinal beam (ie the left crawler frame) and the main frame (Ie the middle frame) and the right longitudinal beam (ie the right crawler frame) are welded into three parts. The weight of the frame assembly is 2 tons.
The central swivel joint is a hydraulic component that connects the slewing platform and the oil circuit of the chassis. It ensures that after the slewing platform rotates at any angle, the walking motor can still distribute oil normally. The current swivel joint is 5-way.
2. Home depot mini excavator working device
The working device is the main component of the hydraulic home depot mini excavator. Currently, the SY series home depot mini excavator is equipped with a backhoe working device. It is mainly used to excavate the soil below the stop surface, but it can also excavate the soil below the maximum cutting height. In addition to digging, trenching, and loading, it can also perform simple site leveling work. Excavation work is suitable for excavating the soil of grade Ⅰ to grade Ⅳ. Hydraulic hammers or blasting methods are required for grade Ⅴ and above.
The backhoe working device is composed of main parts such as boom, stick, bucket, rocker, connecting rod, and working device hydraulic pipeline including boom cylinder, stick cylinder and bucket cylinder.
Three, home depot mini excavator power transmission route table
1. Traveling power transmission route: diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-central rotary joint-traveling motor (hydraulic energy is converted into mechanical energy)-reduction gear box- Drive wheel-track chain crawler-realize walking
2. Rotary movement transmission route: diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-slewing motor (hydraulic energy is converted into mechanical energy)-reduction gear box-slewing bearing-realization turn around
3. Boom movement transmission route: Diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-boom cylinder (hydraulic energy is converted into mechanical energy)-realize boom movement
4. Stick movement transmission route: diesel engine—coupling—hydraulic pump (mechanical energy is converted into hydraulic energy)—distribution valve—stick cylinder (hydraulic energy is converted into mechanical energy)—realize the movement of the stick
5. Bucket movement transmission route: Diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-bucket cylinder (hydraulic energy is converted into mechanical energy)-realizing bucket movement
Fourth, the composition and function of the home depot mini excavator power system
Air intake system-mesh cover → hose → air filter → hose → turbocharger → hose → intercooler → hose → engine·exhaust system—supercharger → expansion joint → muffler → exhaust pipe·cooling system— —Water tank → hose → thermostat → water pump → diesel engine → hose → water tank and throttle control system-stepper motor → reducer → worm gear drive → throttle cable → diesel engine throttle-high idle speed, low idle speed limit switch.
home depot mini excavator fuel system
Fuel inlet system: fuel tank → hose → hand oil pump → coarse filter → fine filter → diesel engine
Oil return system: diesel engine → hose → fuel tank (the oil return volume is relatively large, use it for partial cooling)
