Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mining machine accessories, and concretely relates to a self -adaptation cutting coal mining machine drum. BACKGROUND

[0002] Coal is one of the most important basic energy sources in China and even the world, and its mining efficiency and safety have always been concerned. With the continuous development, maturity and perfection of fully mechanized mining equipment manufacturing and mining technology, and the rapid rise of Internet of Things technology, open -air type environmental protection mining has become the most important development direction of the coal industry.

[0003] The coal mining machine drum is the key working mechanism for coal mining, coal falling and coal loading, and its performance directly affects the overall efficiency and safety of the coal mining machine. In the coal mining process, the coal mining machine drum needs to adapt to coal seams of different thickness, hardness and inclination to ensure efficient mining of coal.

[0004] However, due to the complex and variable geological conditions of coal seams, such as changes in coal seam thickness, uneven coal quality hardness, changes in coal seam inclination, etc., the traditional coal mining machine drum often has difficulty in adapting to these changes during cutting, resulting in low cutting efficiency, increased energy consumption, and even damage to the coal mining machine parts.

[0005] The existing coal mining machine drum can automatically adjust the cutting height and cutting angle according to the changes in the geological conditions of the coal seam, achieving efficient and precise cutting. In addition, the existing coal mining machine integrates sensors, controllers and actuators and other intelligent components to realize real-time sensing, decision-making and execution functions of the drum, improving the adaptability and intelligence level of the coal mining machine.

[0006] However, the self-adaptation of the coal mining machine drum mainly relies on the sensors on it for sensing, and most of the sensors on the coal mining machine drum are directly fixed and installed on the shaft body at the end of the drum. After the drum adjusts the cutting height and cutting angle, the orientation of the sensors will also change, which cannot keep some of the sensors horizontal and aligned with the soil in front, affecting the detection effect of the sensors and further affecting the self-adaptive mining of the coal mining machine relying on the sensors. In view of this, we propose a self-adaptive cutting coal mining machine drum. UTILITY MODEL CONTENTS
