Description

Mining excavator blast pipe protection casing Technical Field The utility model belongs to the technical field of excavators, and particularly relates to an exhaust pipe protective cover of a mining excavator. Background The mining excavator is a hydraulic transmission engineering machine specially used for mining, is mainly used for stripping and mining operation of surface mines, and has large-tonnage loading capacity. The excavator exhaust pipe is an important component of the exhaust system and is responsible for guiding the burned fly out of the engine and safely discharging it to the atmosphere. Because the mine floor roughness is lower, in order to avoid the excavator jolting when working and causing the blast pipe impaired, place the blast pipe in engine compartment top generally, and expose outside generally, in the engine start-up process, if have personnel to overhaul, there is the risk of scalding by the blast pipe. Meanwhile, the excavator usually works in the open air, especially the mining excavator, after long-time sun, wind, rain and showering, the exhaust pipe is easy to rust and perforate, and hidden danger of corrosion and air leakage exists. Disclosure of utility model Aiming at the defects or shortcomings in the prior art, the utility model provides the mining excavator exhaust pipe protective cover which can effectively protect an excavator exhaust pipe, and improves the safety and the service life of the exhaust pipe. In order to achieve the above purpose, the utility model adopts the following technical scheme: The embodiment of the utility model provides a mining excavator exhaust pipe protective cover, which comprises a coaming, side plates, a partition plate and a mounting plate, wherein the partition plate is positioned on the rear side of the coaming, two sides of the coaming are connected with the partition plate through the side plates, and the coaming, the side plates and the partition plate are fixed on the outer side of an excavator exhaust pipe through the mounting plate and are spaced with the excavator exhaust pipe by a set distance. Further, the coaming is formed by bending a steel plate, and the shape of the coaming is matched with the shape of the front side of the exhaust pipe of the excavator. Further, the bounding wall includes the flat board, riser and connecting plate, and the flat board is located the riser top, and the flat board sets up with the riser perpendicularly, and the top of riser links to each other with the one end that the flat board is close to the riser through the connecting plate, the connecting plate slope sets up. Further, the partition plate is formed by bending a steel plate, and the shape of the partition plate is the rear side of the exhaust pipe of the excavator. Further, the baffle includes first vertical section, linkage segment and the vertical section of second, links to each other through the linkage segment between the vertical section of first and the vertical section of second, and linkage segment slope setting.
