Crawler-mounted counterattack mobile station

Description

The crawler type impact mobile crushing station is composed of track chassis, frame assembly, main engine and auxiliary equipment, power system and hydraulic electronic control system. When moving, the power is provided by the power system, and the hydraulic electronic control system drives the track chassis to walk; During installation, the power system drives the hydraulic cylinder and other actions through the hydraulic electronic control system to automatically complete the equipment installation; When working, the power system drives and controls the main engine and auxiliary equipment through the hydraulic electronic control system. After the material enters the main engine mounted on the track chassis and frame from the silo, it is broken or screened, and discharged through the integrated belt conveyor.

Performance Advantages

• Excellent performance of the power system, using Cummins diesel engine, low fuel consumption, low noise, reliable performance, to provide a reliable, economic, environmental protection power source. The engine can be equipped with a military low temperature preheating start device, so that the equipment can be easily started in a low temperature environment of -25C°.
• The all-steel ship structure chassis has the characteristics of high strength, low ground ratio, etc., and has a good adaptability to mountains and wetlands.
• Large torque motor, driving force, high reliability. The walking system adopts full power variable open hydraulic system, excellent performance, high reliability, can make full use of the power of the engine, the main hydraulic parts (pumps, valves, etc.) are imported from Japan to provide reliable power support for the walking system.
• Imported servo pilot operating system, easy to operate, accurate control, can achieve endless variable speed walking.
• Crushing and screening equipment are selected from the company's own production of mature products, such as jaw breaking, counterattack breaking, cone breaking, etc., compact structure, stable performance, reliable.
• Hybrid pressure energy device, dual power intelligent transfer switch, can make full use of local power resources, save operating costs, reduce CO2 and nitrogen oxide emissions. Once the power is interrupted or undervoltage, the diesel generator automatically switches to generate electricity to ensure continuous operation of the equipment.

Question&Answer

Q:What are the breakable parts? What is the service life?

A:The most important wearing parts are hammer, counter plate, side lining plate, etc., the service life is about 1 month (or even a week), 2 months, 3 months, the specific service life needs to be based on the actual situation, generally in the configuration of wearing parts, the configuration ratio of the three is 3:2:1.

Q:What are the ways of fixing the plate hammer? What are the advantages and disadvantages of each?

A:There are three common types: screw fixation, pressure plate fixation and wedge fixation. Screw fixation: The screw is exposed to the hitting surface, which is easily damaged, and the screw is subjected to a large shear force, which will cause serious accidents once it is cut. Clamping plate: the plate hammer is inserted into the groove of the rotor from the side, and both ends are pressed by clamping plate. However, this fixing method makes the plate hammer not firm enough, and the plate hammer is easy to loose during work. (need to be welded, the pressure plate is easy to wear and replacement is not easy) wedge fixing: using the wedge to fix the plate hammer on the rotor, under the action of centrifugal force in the work, this fixing method can ensure that the faster the rotor speed, the stronger the plate hammer is fixed, and the work is reliable, and the replacement is more convenient. This is a better fixing method for the plate hammer at present.
