Working principle of excavator loader used in coal mines（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will introduce the working principle of the excavator loader used in coal mines.

The mining loader used in coal mines is a comprehensive engineering machinery that integrates excavation, loading, and transportation. Its powerful operational capabilities and efficient operating modes significantly improve the efficiency and safety of underground operations. Below, we will delve into the working principle and key technologies of mining loaders used in coal mines.

1、 Overview of workflow

Startup phase: After confirming the safety of the surrounding environment and setting all operating parameters, the operator starts the engine and all components enter working state.

Excavation operation: With the help of front-end excavation tools such as buckets or grab buckets, mining loaders are used in coal mines to cut or grab materials such as ore and soil. This process is usually powered by a hydraulic system to ensure precise and powerful movements.

Loading and transfer: The excavated materials are immediately loaded onto the conveyor belt above the machine body, and then transported to the vehicle or fixed storage bin.

Transportation and Unloading: After loading, the mining loader used in coal mines can move freely within a limited space due to its excellent maneuverability and adaptability, transporting materials to predetermined unloading points or directly pouring them into transport trucks.

Auxiliary cleaning and maintenance: In order to ensure the smooth progress of subsequent work, the mining loader used in coal mines is also responsible for the preliminary cleaning of the work area, as well as regular equipment maintenance, including cleaning the machine body, inspecting worn parts, etc.

2、 Key Technology Analysis

1. Hydraulic drive system: This system is one of the power sources for mining excavator loaders, used to control functions such as excavation, loading, and walking, ensuring smooth and efficient operation while also facilitating fine operation.
2. Structure and design of robotic arm: The excavation part often adopts telescopic arm or multi joint design, combined with excavation tools made of high hardness materials, which can demonstrate sufficient strength and flexibility when facing different types of geology.
3. Conveyor mechanism: There is a dedicated conveyor mechanism inside for the rapid transfer of materials, reducing on-site downtime and improving overall efficiency.
4. Safety protection: Equipped with multiple safety facilities such as lighting, alarms, and emergency stop buttons to ensure the safety of operators and equipment.

From the above description, it can be seen that the excavator loader used in coal mines combines multiple advanced technologies and has become an important tool in mineral mining, achieving mechanization and automation of underground operations, marking the direction of technological progress and innovation in the mining industry.
