The excavator's breaker hammer, being an important auxiliary tool of heavy construction machinery, plays an indispensable role in construction, mining, road construction, and building demolition due to its powerful crushing ability and wide range of applications. Below is a detailed description of the excavator's breaker hammer:

Definition and Overview 
The excavator's breaker hammer, as the name suggests, is a type of hydraulic breaking equipment mounted on an excavator. It is powered through a hydraulic system and uses high-speed impacts to transfer energy to the object being destroyed, thereby achieving the crushing and demolition of concrete structures, stones, and other hard materials. As an important working tool of the excavator, the emergence of the breaker hammer significantly enhances construction efficiency and operational flexibility.

Structural Composition 
The excavator's breaker hammer mainly consists of the following key components:
Housing: The housing completely envelops the hammer body and is filled with vibration-damping materials to reduce vibration and noise. The design of the housing not only protects the internal structure of the hammer but also ensures safe operation.
Hammer body: The hammer body is the main component of the breaker hammer, including the piston, welding rod, and other key elements. The piston is driven by the hydraulic system, performing reciprocating movements, thus striking the welding rod and creating a powerful crushing force.
Hydraulic system: The hydraulic system is the power source of the breaker hammer, including the hydraulic pump, hydraulic cylinder, hydraulic pipeline, control valve, and other components. The hydraulic pump directs hydraulic oil into the hydraulic cylinder, creating high-pressure hydraulic pressure and pushing the piston to move.
Control system: The control system is responsible for managing the operation of the hydraulic system, including the flow and pressure of hydraulic oil, as well as the opening and closing and frequency of the breaker hammer's operation. The operator issues commands through the excavator's control lever, and the control system receives commands and manages the operation of the hydraulic system.

Working Principle 
The working principle of the excavator's breaker hammer is based on the principle of hydraulic transmission and impact crushing. When the hydraulic system is activated, the hydraulic pump sends hydraulic oil into the hydraulic cylinder, creating high-pressure hydraulic pressure. This high-pressure liquid pressure pushes the piston into a reciprocating motion, thus striking the welding rod. Upon impact, the rod generates high-speed impact force, which is transmitted to the object being destroyed by the pointed or flat head of the hammer. Under the action of the high-speed impact force, cracks form on the object, and it gradually breaks apart. Meanwhile, the hydraulic system can also control the opening and closing and frequency of the breaker hammer to adapt to different materials and various crushing needs.

Operational Characteristics 
Strong crushing force: The excavator's breaker hammer uses high-strength materials and precise design, which can generate strong crushing force and easily handle the crushing operation of various hard materials.
High work efficiency: The working principle of the breaker hammer determines its fast working speed and high efficiency. It can perform more crushing tasks at the same time and enhance construction efficiency.
Good stability: The vibration-damping design of the housing and precise control of the hydraulic system ensure the stability and reliability of the hammer during operation.
Low noise level: The wrapping of the housing and the use of vibration-damping materials reduce noise pollution during the hammer's operation and enhance the comfort of the working environment.
Convenient maintenance: The structure of the breaker hammer is reasonably designed, making it easy to maintain and repair. During operation, it is only necessary to regularly check and replace hydraulic oil and worn parts to ensure normal working conditions.

Areas of Application 
The excavator's breaker hammer is widely used in the following areas:
Construction: In the process of demolition and reconstruction of buildings, the breaker hammer can quickly crush concrete structures, steel bars, and other obstacles, increasing demolition efficiency and reducing noise and dust pollution.
Mining industry: In the mining industry, breaker hammers can crush hard materials such as ores and stones, increasing mining efficiency and reducing mining costs.
Road construction: In the process of road construction and maintenance, breaker hammers can be used to destroy road surfaces, excavate stones, and perform other operations that facilitate the laying of new road surfaces or the repair of damaged road surfaces.
Demolition: During the demolition of bridges, the destruction of factories, and other operations, breaker hammers can effectively demolish various structures and objects, reducing demolition time and labor costs.
