Down-hole water warehouse coal slurry digging device

Abstract

The invention relates to an underground sump coal slurry excavation device for cleaning the silted coal slurry in the underground sump, which can be used in excavation, transportation and cleaning, mainly comprising an excavation screw, a transportation scraper, a swing device, a walking pallet, a transportation screw and a concentrated material pump, wherein, the excavation screw is arranged in front of the whole device and the screw is shaft less. One end of the transportation scraper is connected with middle section of the excavation screw as a whole and the other end is arranged above a feed inlet of the transportation screw. One end of the transportation screw is arranged at the lower side of the discharge end of the transportation scraper and the other end is connected with the feed inlet of the concentrated material pump. The concentrated material pump is arranged above the walking pallet and at the back side of the whole device. One end of the swing device is connected with the excavation screw and the other end is hinged with the walking pallet. One end of a hauling oil cylinder is connected with the walking pallet and the other end is hinged with the swing device. The invention has the advantages of reducing labor intensity for workers largely, and improving productivity of cleaning the sump.

Description

technical field [0001] The invention relates to a coal mine underground coal slime dredging device in the field of mining machinery, in particular to an underground water tank coal slime dredging device integrating excavation, transportation and cleaning when cleaning the silted coal slime in the coal mine underground water tank. Background technique [0002] In the mine construction process of coal mines, each mine must have a mine water tank, which is used to accommodate the water gushing that occurs in the normal mining process of the mine. Because the mine water flowing into the water tank is mixed with a large amount of coal powder, the coal slime is deposited in the water tank, which seriously affects the normal water storage capacity of the water tank and must be cleaned. It is stipulated in the relevant coal mine safety production that before the rainy season every year, the coal slime deposited in the water tank must be cleaned. [0003] At present, there are two w...
