[0002] According to the requirements of the Coal Mine Safety Regulations, sedimentation tanks shall also be provided for water-sand filling and other mines with a large amount of impurities in the inflowing water. The empty bunker capacity of the sump shall always be maintained at more than 50% of the total capacity. The sludge in the sump, sedimentation tank and drainage ditch shall be cleaned in time and must be cleaned once before the rainy season every year.

[0003] During the actual production process of coal mines, a large amount of sewage from the coal mining face and the tunneling face contains particulate matter and cannot be completely sedimented in the sedimentation tank before entering the sump. This causes the sump to silt up rapidly in a short period of time, affecting the production safety underground. Therefore, it is necessary to frequently clean the sedimentation tank and the sump to ensure the effective capacity of the sedimentation tank and the sump.

[0004] At present, in order to use the sedimentation tank and the sump normally, manual regular and frequent excavation is required. Due to the lack of effective mechanical auxiliary equipment, the cleaning difficulty is high, resulting in a large labor intensity of the personnel and a low excavation efficiency. For mechanical bunker cleaning equipment, the mechanism is relatively complex, the operation is inconvenient, the overall volume of the equipment is large, it is not convenient to move underground in coal mines, and the mobility is poor, so it is not suitable for narrow roadways. Therefore, how to overcome the above-mentioned technical problems and defects has become the key problem to be solved. Summary of the Utility Model
