Rock loader, loader, excavator, slag scraper, plate bender. Are all these machines the same? Who can tell me the difference?

Loader is a kind of earthwork machinery, which is widely used in highway, railway, construction, hydropower, port, mine and other construction projects. Mainly used for bulk materials such as shovel, sand, lime and coal. , but also light shovel light mining materials and hard soil.

Excavators, also known as digging machines, are earth-moving machines that use buckets to dig materials above or below the bearing surface, load them into transport vehicles or unload them into the yard.

The main uses of slag dredger are: construction machinery for tunnel excavation, mining engineering, water conservancy engineering and other projects, small cross-section diversion tunnel, and mine slag (ore) machinery. This machine is mainly used for the collection, transportation and loading construction of gravel soil materials in some non-explosive mines with narrow production space and small production scale, such as phosphate rock, metal non-metallic mines and so on. Features of the slag scraper: It is a production equipment that combines manipulator and conveyor, integrates collection and transportation functions, adopts electro-hydraulic control system, and 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, and it is a substitute for manpower and other machinery. The advantage of slag scraper is that it includes five functions: hydraulic walking, excavation and collection, transportation, loading and bottom cleaning. Among them, the hydraulic walking function is to drive the wheels through the hydraulic motor, reducer, transmission shaft and reducer. The hydraulic motor has three functions: forward, backward and automatic braking. The digging and collecting function is completed by the manipulator, which has the functions of digging, stretching, loading and unloading, etc. The boom can be raised, lowered and rotated left and right. The digging and collecting operations are controlled by full hydraulic pressure and operated by six handles, and each handle controls two actions, totaling twelve actions. This technology is improved by using the working process of large excavator, which is convenient to use and simple to operate. The conveying and loading functions are completed by the conveying system, and the lifting of the conveying frame is controlled by the hydraulic cylinder. When the conveyor frame descends, it can support the front wheel, and at the same time, the front receiving port of the conveyor frame is closer to the contact surface of the ore, which makes it more stable when working. At the same time, the conveyor belt is smooth and normal, the width of the conveyor belt is 650- 700mm, and the transmission speed is 800-900 mm/s. The 2.2kw motor on the conveyor belt drives the reducer to drive the roller. This way, the transmission performance is more stable, the service life is longer and the maintenance is more convenient. Most of the slag scrapers used in tunnel construction are ITC3 12 models made in Germany, and their theoretical slag loading capacity is 3 12 cubic meters/hour, which is the largest number of models owned by domestic tunnel equipment enterprises and the most efficient and stable model for slag loading. Compared with the only Japanese-made model of the same specification, it has a high evaluation. In 2009, the Ministry of Railways of China designated the localization of large-scale slag scrapers (tunnel excavators and loaders) as scientific and technological projects, which were developed by Shijiazhuang Railway Institute and finally produced by China People's Liberation Army 64 1 1 Factory. This model is WZ330, and its appearance is similar to ITC3 12. Its hydraulic, power and motor components are still imported from internationally renowned brands, which can reach the slag loading capacity and stability of ITC3 12. The electro-hydraulic proportional control and regulated power supply have been improved, making it more suitable for long tunnel construction. However, like most domestic high imitation products, they are internal organs imported from domestic shells, and the soup has not been changed. The slag scraper has changed the state of semi-mechanization, intermittent slag discharge and loading, requiring a lot of manual cooperation, slow speed, high safety risk and high cost. It integrates the functions of scraping, digging, harrowing, loading, transporting and unloading, and has six functions of walking, digging, collecting, transporting, loading and clearing, thus achieving continuous and efficient production. It is to ensure high yield, high efficiency, low safety risk and low cost in the current narrow site construction; Enhance market competitiveness; Improve the production schedule and quickly occupy the market; Exceeding the task duration ahead of schedule and other visible results.

Rock loader English: explanation of rock loader: a machine for loading ore or rock in a horizontal or gently inclined tunnel. According to the working principle, it is divided into claw, crab claw, bucket and rake; According to the power used, it can be divided into electric, pneumatic and diesel engine drive. When the bucket loader works, the fuselage moves forward, the bucket descends and inserts into the rock pile, then the bucket lifts, the fuselage retreats, and the bucket overturns the rocks in the mine car or other transfer equipment hanging behind the fuselage. Its work is more flexible and reliable, and the rock loading productivity is also higher. It is a widely used loading equipment at home and abroad. Geological exploration 1A rail loader and bucket loader have basically the same structure, and are suitable for use in geological exploration roadways.
