Description

Technical Field

[0001] The utility model relates to the technical field of coal mining in coal mines, in particular to a comprehensive coal digging device. Background Art

[0002] For short-distance excavation of underground coal tunnels, the traditional technology mostly uses a multi-purpose excavator with an SGB-420 / 40Z scraper for delivery. When the tunnel distance is not long enough to install the second transport of the multi-purpose excavator, the scraper is laid from the bottom of the multi-purpose excavator to the front. The multi-purpose excavator is restricted by the scraper, and its movement and steering are greatly limited, which is not conducive to safe production. At the same time, due to the rolling and collision of the multi-purpose excavator, the failure rate of the scraper is high. When the tunnel distance is long enough to install the second transport of the multi-purpose excavator, a set of sliding shoes is installed under the second transport and straddled on both sides of the scraper. Because the tunnel floor is soft, the second transport sliding shoes plow deeper and deeper due to their own weight during the movement of the multi-purpose excavator.

[0003] At present, a comprehensive coal excavation device is required when a comprehensive excavator is working. However, the comprehensive coal excavation device in the prior art still has some disadvantages when in use. It is inconvenient to collect the fallen coal blocks, and the protective effect is not good. The collecting components are easily damaged, thereby reducing the coal output efficiency. For this reason, we propose a comprehensive coal excavation device to solve the above problems. Utility Model Content
