[0002] Because of its large load capacity, strong climbing ability, and the advantages of integrating shoveling, transportation and unloading functions, rubber-tyred trackless vehicles are widely used in underground mine operations. The underground mine operation environment is complex, and trackless rubber-tyred vehicles are often faced with the risk of scratches from objects such as stones and supporting materials during driving, especially the muffler, because it is installed at the bottom of the vehicle and protrudes from the vehicle body, the chance of being scratched is higher. As a prior art, the design of mufflers often ignores their anti-scratch performance in the complex environment of the mine.
[0003] On the other hand, the engine of the mining trackless rubber-tyred vehicle will produce higher frequency noise than ordinary engineering vehicles during operation, which will have an adverse impact on the health of underground workers and the ecological environment of the mine. Therefore, it is necessary to improve the structure of the existing mining trackless rubber-tyred vehicle muffler to further reduce the impact of the engine noise of the underground mining trackless rubber-tyred vehicle on the environment. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an improved muffler for underground mine trackless rubber-tyred vehicles, firstly, to improve the anti-scratch ability of the muffler for underground mine trackless rubber-tyred vehicles; secondly, to further reduce the impact of the engine noise of the underground mine trackless rubber-tyred vehicles on the environment.
[0005] The technical solution of the utility model is as follows:
[0006] An improved muffler for underground mining trackless rubber-wheeled vehicles, comprising a protective box and a muffler exhaust pipe installed in the protective box, the protective box being surrounded by a top plate, a bottom plate, a rear side plate in the shape of a right-angle plate, and a front side plate in the form of a bent plate; the front side plate comprises a panel and folding plates on the left and right sides of the panel; the edges of the folding plates are fixed to the front side of the rear side plate by welding; the top plate and the bottom plate are welded to the upper and lower ends of the rear side plate and the front side plate respectively; the top plate and the bottom plate have the same shape and size, both of which are irregular pentagonal flat plates with a right angle, and their two right-angled sides are respectively welded to the two right-angled plates of the rear side plate; the upper end of the muffler exhaust pipe passes through the top plate, and the bottom end is blocked by the bottom plate; the pipe wall of the muffler exhaust pipe is fixedly connected with a plurality of filter plates arranged up and down; the pipe wall of the muffler exhaust pipe is provided with air vents located between adjacent filter plates; the filter plate is also provided with air vents; and the protective box is also provided with an exhaust port.
[0007] Preferably, a flange for connecting to an engine exhaust pipe is installed at the outlet end of the silencer exhaust pipe; the outlet portion is sealed by a sealing gasket or welding.
[0008] Preferably, the exhaust port is opened at the bottom of the panel of the front side plate.
[0009] Preferably, the outer sides of the two right-angle plates are respectively processed with a plurality of bolt mounting holes arranged up and down, and the mounting holes are used to pass through fixing bolts connected to the muffler mounting plate of the rubber-tyred trackless vehicle body.
[0010] The utility model proposes an improved muffler for an underground mining trackless rubber-tyred vehicle, which not only has an excellent noise reduction effect, but also can effectively prevent scratches in a complex underground environment through a unique design, thereby improving the reliability and safety of the equipment.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] First, the rear side panel of the protective box of the utility model has two wall panels at right angles to each other. The two wall panels at right angles to each other and the muffler mounting plate of the rubber-wheeled trackless vehicle body are fixed by fixing bolts, and the structural strength is greater. The front side panel of the protective box body has a bevel design, and the scratch angle is reduced. Even if a head-on collision occurs, the muffler is not easily displaced or deformed due to the large connecting surface area of the right-angle plate. Even if it is scratched by underground rocks or supporting materials, it is not easy to deform and will not fall off. Therefore, the utility model has a compact installation, a firm structure, is not easy to deform, and can better prevent the muffler from falling off due to scratches.
[0013] Second, the bottom of the exhaust pipe of the utility model is blocked, and the high-speed exhaust gas is discharged from the exhaust holes on the side wall of the exhaust pipe, and is discharged to the tail end layer by layer through the holes on the filter plate. The vibration impact of the high-speed airflow is effectively dispersed, further reducing the noise frequency of the high-speed exhaust gas after passing through the muffler.
[0014] Third, in the optimized technical solution of the utility model, the exhaust port of the muffler is designed at the lower part of the front side plate, and the exhaust is directed to one side instead of downward, so it is not easy to blow up road dust when used underground.
