Preferably, the pin track is of a side-hung structure.

Compared with the prior art, the invention has the beneficial effects that:

1. according to the scraper conveyor, through the improvement of the structure, the driving structure is not arranged at the head and the tail of the scraper conveyor, and the driving structure is distributed on the middle groove body, so that the tension of the scraper chain is reduced, the diameter of the chain is reduced, the traction force is reduced, the energy consumption is greatly reduced, and the scraper conveyor is far superior to the prior art.

2. The invention increases the pedestrian space of the nose and the tail by improving the nose and the tail, can correspondingly reduce the unloading height of the nose and the tail, reduces the power loss, and is a novel scraper conveyor with small volume, large transportation capacity and stable operation.

3. The invention is a multipoint drive, because the number of drives is increased, less than 30 percent of the drives can still normally run when a fault occurs, and the overall reliability is greatly improved

In conclusion, the coal mine water-saving device is ingenious in design, reasonable in structure, and free of great improvement on the prior art, effectively improves the economic benefit of a coal mine, and has great popularization significance.
