3. Each has its own merits
loader is a kind of earthwork construction machinery which is widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling soil, sand, lime, coal and other bulk materials, and can also be used for light shoveling of ore and hard soil
excavator, also known as excavating machine, is a kind of earth moving machine which uses bucket to excavate materials higher or lower than the bearing surface and load them into transport vehicles or unload them to the stockyard< The machine is mainly used for tunnel excavation, mining engineering, water conservancy engineering construction machinery and small section diversion tunnel, mine slag (ore) machinery. The machine is mainly used for gravel soil material collection, transportation and loading construction in some non explosive dangerous mines with narrow proction liquid space and small proction scale, such as phosphate rock, metal and non-metal ore. Features of slag raking machine: it is a proction device that combines the manipulator and conveyor, integrates the collection and conveying functions, and adopts the electro-hydraulic control system. It has the characteristics of safety, environmental protection, low energy consumption and high efficiency. It is an indispensable advanced mining equipment for mines and small tunnels. It is an alternative proct for human and other machinery. The advantages of slag raking machine: it has five functions: hydraulic walking, excavation, collection, transportation, loading and bottom cleaning. Among them, the hydraulic walking function is to drive the wheels through the hydraulic motor, recer, transmission shaft, and then to the recer. The hydraulic motor has three functions: forward, backward and automatic braking; The digging and collecting function is completed by the manipulator. The manipulator has the functions of digging, extending arm, loading and unloading. The boom can rise, fall and rotate left and right. The operation of digging and collecting is controlled by full hydraulic pressure. It is operated by six handles, and each handle controls two actions, a total of 12 actions. This technology is improved by the operation process of large excavator, which is easy to operate and transport, The loading function is completed by the conveyor system. The lifting of the conveyor frame is controlled by the hydraulic cylinder. When the conveyor frame descends, the front wheel can be supported. At the same time, the front material receiving port of the conveyor frame is more close to the ore contact surface, so the stability is stronger. At the same time, the bulk material can be joined, and the conveyor belt width is 650-700mm, and the transmission speed is 800-900mm / s, Another 2.2kW motor drives the recer to drive the driving roller, which makes the transmission performance more stable, the service life longer and the maintenance more convenient. Most of the slag raking machines used in tunnel construction are German made itc312, with a theoretical slag loading capacity of 312 cubic meters per hour. It is the model with the largest number of tunnel equipment enterprises in China, and also the model with the highest slag loading efficiency and the most stable performance. It has a high evaluation with the same specification of only Nissan model. In 2009, China's Ministry of Railways designated the localization of large-scale slag raking machine (tunnel digging and loading machine) as a science and technology project, which was researched and developed by Shijiazhuang Railway Institute and finally proced by the 6411 factory of the Chinese people's Liberation Army. WZ330 is similar to itc312 in appearance, and its hydraulic, power, motor and other components are still imported international famous brands, so it can achieve the slag loading capacity and stability of itc312. The electro-hydraulic proportional control and regulated power supply are improved to make it more suitable for large and long tunnel construction, but like most domestic high imitation procts, it is imported from domestic shell, The soup didn't change the dressing. Slag raking machine has changed the original construction of semi mechanized, intermittent slag transportation and requires a lot of manual cooperation of low speed, high safety risk and high cost. The slag raking machine integrates raking, digging, raking, loading, transporting and unloading. It has six functions of walking, digging, collecting, transporting, loading and cleaning the site.
