● Power system: adopts Dongfanghong 4110 supercharged and intercooled engine, with mature and stable technology, sufficient air intake, full combustion, stronger power, and more suitable for working in high altitude areas; low failure rate, simple maintenance, adapt to high temperature and humidity underground And other bad working conditions. 1. In recent years, domestic engines have been mature and stable in technology. They adopt turbocharged intercooled engines, which are more suitable for working at high altitudes. They have sufficient air intake, sufficient combustion, stronger power, and less roadway pollution, while imported engines are only naturally aspirated. The engine has no supercharging and intercooling, and the air intake is insufficient, so it is not suitable for high altitude operation. 2. The engine is more cost-effective. The equipment working environment in the tunnel is bad (humidity, dust, etc.), labor intensity is high (8-20 hours/day), and untimely maintenance and other factors can easily cause early engine wear, black smoke, and power after one year. Problems such as descent need to be overhauled. Imported engine maintenance costs are high, the cost of a major overhaul ranges from 30,000 to 40,000 yuan, and some parts need to be purchased from abroad, and the waiting time is long; while the domestic engine assembly price is about 30,000 yuan, and the parts are universal and the price is lower. Easier to purchase.
● Transmission system: Shantui torque converter gearbox is used to replace American Dana, with three forward gears and three reverse gears, with a large transmission range, and is matched with a closed multi-disc wet brake drive axle special for mining machinery with high speed ratio, with large input torque. The transmission efficiency is high, the work is stable, and the low speed and large torque are realized, which makes the first gear shovel load more powerful, the bucket is easy to fill, and the work efficiency is high. Superior performance, easy maintenance, and cost reduction.
● Working system: It adopts hydraulic pilot control instead of mechanical control, which is lighter and more flexible. In addition, precision filters are used in each hydraulic circuit to protect hydraulic components and reduce failure rate.
● Electrical system: It is designed to be waterproof and moisture-proof to adapt to wet conditions in underground mines.
● Brake system: The service brake is a multi-disc wet brake, and the parking brake is a spring brake and hydraulic release, which makes the brake safe and reliable. Wet brakes wrap the brake discs, brake calipers, and brake pads and lubricate them with oil. The mud, sand and water mixture cannot enter, avoiding damage to the brake components. Within two years, there is no need to replace the brake components, reducing the frequency of maintenance, and the braking effect is better.
● Exhaust gas purification system: adopts water filtration device + oxidation catalyst to achieve two-stage filtration. Exhaust gas is discharged in the form of water mist and quickly settles to the ground, which greatly reduces air pollution and protects the roadway environment and the physical and mental health of the driver.
● The engine air intake adopts an oil-bath air filter, which replaces the ordinary paper air filter (the paper filter element will be deformed and blocked due to the moisture in the intake air and lose the filtering effect), and there is no need to replace the filter element.
● The steering device is operated by a pilot handle instead of imported machinery, which makes the operation lighter and the steering more precise.
● The steel frame of the vehicle is thickened, and the rigidity of the vehicle is enhanced. The bucket blade is made of high-strength alloy steel, which is wear-resistant and shear-resistant. The V-shaped structure reduces the resistance of shoveling and has a longer service life.
● Smooth wear-resistant and puncture-resistant tires are used, and four tire protection chains are used to make the tires have a longer service life.
● Strong climbing ability, with a full load of up to 16°, it can be used for excavation of slopes within 25° with the assistance of a hoist, instead of a slag raking machine.
● The rear frame of the machine can be disassembled into 5 parts, which is convenient for going down the well.
● The machine is compact in structure and easy to operate. It can perform integrated operations of shoveling, loading, transporting and unloading. It has high work efficiency and is suitable for mining and digging of roadways, as well as auxiliary operations such as construction and leveling of work sites and roads, and material transportation.
