Description

Technical Field

[0001] The invention relates to the technical field of coal loading and unloading, and in particular to coal loading and unloading equipment. Background Art

[0002] As an important fossil fuel, coal plays an irreplaceable role in energy supply and industrial development. China's coal is divided into ten categories. Generally, lean coal, coking coal, fat coal, gas coal, weakly sticky coal, non-sticky coal, long flame coal, etc. are collectively referred to as bituminous coal; lean coal is called semi-anthracite; and coal with a volatile matter content greater than 40% is called lignite.

[0003] The traditional coal loading process relies heavily on manual operation or relatively basic mechanical equipment. It is difficult to ensure that the distribution of coal in each loading is highly uniform, which can easily lead to inconsistent center of gravity of the coal-loading vehicle and unstable driving of the vehicle, which not only affects the overall efficiency of loading, but also brings potential safety hazards to the transportation process. In addition, a large amount of coal dust will be generated during the coal loading and unloading process, which causes serious pollution to the working environment. Coal dust not only permeates the air, reducing the visibility of the working area, but also may adhere to equipment, tools and personnel's clothing, making it difficult to completely remove. Working in such an environment for a long time, operators not only face health threats to the respiratory system, such as occupational diseases such as pneumoconiosis that may be caused by inhaling coal dust, but also may cause discomfort and disease due to irritation of the eyes and skin by coal dust.
