The overall structure, working principle, and performance of the excavator loader used in coal mines（haoyun）

The editor of Donghaoyun Heavy Industry Machinery Co., Ltd. will provide the following explanation on the overall structure, working principle, and performance of the excavator loader.

This device consists of four major mechanisms: driving, excavating, conveying, and loading, as well as two major systems: hydraulic and electrical. Its powerful functionality benefits from the coordination and cooperation of its various parts. By using hydraulic and electrical actuators and mechanical transmission mechanisms, specified actions can be achieved and various work processes can be completed.

This equipment from Shandong Haoyun Heavy Industry has four functions: hydraulic walking, excavation and collection, conveying, and loading. Among them, the hydraulic motor drives the front and rear wheels, which can achieve wave pressure walking function, including forward, backward, and automatic braking performance. And four-wheel drive has the characteristics of strong ground force and strong driving force. The excavation and collection function is completed by a robotic arm, which can perform actions such as excavation, arm extension, loading, and unloading. The upper arm can be raised, lowered, and rotated left and right, making excavation and collection operations more convenient.

The transportation and loading functions are completed by the conveyor system. The conveyor frame is controlled by hydraulic cylinders for lifting and lowering. When the conveyor frame descends, the front wheels can be supported, and at the same time, the front feeding port of the conveyor frame is in closer contact with the ore, resulting in stronger stability during operation. It can collect bulk materials, level the ground, and has high practicality. Driven by a hydraulic motor, the drum ensures more stable performance and longer service life of the conveyor.

The hydraulic system of the entire vehicle is powered by a motor that drives a dual high-pressure gear pump. Wave pressure oil is input into a multi way directional valve through the gear pump, and the control of each hydraulic device is achieved through the operation handle. This makes the operation simpler and more convenient.

The vehicle electrical system adopts a mining explosion-proof electromagnetic starter to control the motor and ensure the safety of personnel and equipment.

Overall, Shandong Haoyun Heavy Industry’s excavator loader combines multiple functions, making work more convenient and improving efficiency. Whether it’s walking, digging and collecting, or transporting and loading, it can be easily handled. I hope everyone can enjoy it and enjoy the convenience it brings during use.
