An exhaust system for a mining truck

Abstract

This invention relates to the field of mining truck technology, and more particularly to a mining truck exhaust system, comprising: a truck exhaust pipe and a hopper. The truck exhaust pipe is located on the lower surface of the hopper, and a reversing device is installed on the exhaust pipe. The reversing device can change the exhaust path of the exhaust pipe. In winter, when it snows, the exhaust pipe is directed to a long pipe through the reversing device. The long pipe is a heat-conducting pipe, which transfers the heat of the smoke to the hopper. After the hopper is heated, the snow and ice quickly melt, and the melted snow and ice flow out of the truck hopper as water. In seasons without snow or after the snow has been cleared, the pipe is switched to a short pipe, which is a noise-reducing pipe, effectively reducing the noise of the truck exhaust pipe. This effectively solves the problems of snow accumulation inside the truck hopper, the time-consuming snow and ice removal by workers, which affects the efficiency of mining truck use, and the noise problem caused by the large exhaust volume of the engine during operation.

Description

Technical Field

[0001] This invention relates to the field of smoke extraction technology for mining trucks, and more particularly to a smoke extraction system for mining trucks. Background Technology

[0002] During the use of mining truck exhaust pipes, snowfall is common in northern winters, causing snow to accumulate inside the truck bed. This snow and ice can reduce the actual transport space in the truck bed, and the time spent by workers removing snow and ice can affect the efficiency of the mining truck. In addition, the large amount of exhaust gas emitted by the engine during operation can cause noise problems in the exhaust pipe. Summary of the Invention

[0003] The purpose of this invention is to provide a smoke exhaust system for mining trucks to solve the problems of snow and ice accumulation in the truck bed during winter and noise from the exhaust pipes in existing technologies.

[0004] To achieve this objective, the present invention adopts the following technical solution: A smoke extraction system for mining trucks, comprising: The truck exhaust pipe and hopper are installed on the lower surface of the hopper. A reversing device is installed on the exhaust pipe to change the exhaust path of the exhaust pipe.

[0006] Preferably, the groove includes a collecting section and a discharging section, the collecting section being connected to the discharging section, and the height of the collecting section decreasing sequentially from the discharging section to the discharging section.

[0007] Preferably, the collecting section is square and the discharging section is trapezoidal.

[0008] Preferably, the truck exhaust pipe includes a main pipe, a noise reduction pipe, and a heat conduction pipe. The noise reduction pipe is arranged along the width of the hopper, and the heat conduction pipe is arranged along the length of the hopper. The commutator is installed on the main pipe and connected to the noise reduction pipe or the heat conduction pipe.

[0009] As a preferred option, the materials for the main pipeline noise reduction pipeline and the heat conduction pipeline are both made of ferritic stainless steel.

[0013] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0014] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0015] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0016] like Figures 1-2As shown, this embodiment provides a mine truck exhaust system, including: a truck exhaust pipe 1 and a hopper 2. The truck exhaust pipe 1 is installed on the lower surface of the hopper 2. A reversing device 3 is installed on the truck exhaust pipe 1, which can change the exhaust path of the truck exhaust pipe 1. In winter, when it snows, the reversing device 3 guides the exhaust pipe to a long pipe, which is a heat-conducting pipe 13. The heat-conducting pipe 13 transfers the heat of the smoke to the hopper 2. After the hopper 2 is heated, it quickly melts the snow and ice, and the snow and ice melt into water and flow out. In the off-season or after snow removal, the pipeline of truck hopper 2 is switched to a short pipeline, which is a noise reduction pipeline 12. This effectively reduces the noise of the truck exhaust pipe. Through the pipeline position and the setting of the commutator 3, the problem of snow accumulation inside the truck hopper 2 in the existing technology is effectively solved. Snow and ice will occupy the actual transportation space of the mining truck hopper, and the time spent by workers to remove snow and ice will affect the efficiency of the mining truck. During operation, there is also the problem of large exhaust volume of the engine causing noise in the exhaust pipe.

[0017] Specifically, the hopper 2 is provided with an inclined groove 21, which is located above the exhaust pipe. The groove 21 heats and melts the snow, and the melted water flows back out of the truck hopper 2. The melted snow is guided out, which can effectively remove the snow and prevent the snow from affecting the loading volume of the hopper 2.

[0018] Specifically, the groove 21 includes a collecting part 211 and a discharging part 212. The collecting part 211 is connected to the discharging part 212. The height of the collecting part 211 to the discharging part 212 decreases sequentially. The collecting part 211 is square and the discharging part 212 is trapezoidal, which increases the drainage speed without affecting the loading volume, and at the same time facilitates unloading from the hopper 2.

[0019] Specifically, the truck exhaust pipe 1 includes a main pipe 11, a noise reduction pipe 12, and a heat conduction pipe 13. The noise reduction pipe 12 is arranged along the width direction of the hopper 2, and the heat conduction pipe 13 is arranged along the length direction of the hopper 2. A commutator 3 is installed on the main pipe 11 and connected to the noise reduction pipe 12 or the heat conduction pipe 13. When it is necessary to remove snow, the commutator 3 connects the exhaust pipe to the heat conduction pipe 13. The heat conduction pipe 13 transfers heat to the truck bed. After the snow in the truck bed melts, it is discharged to the outside of the truck bed through the collection part 211 and the discharge part 212.

[0020] Specifically, the materials of the main pipeline 11, the noise reduction pipeline 12, and the heat conduction pipeline 13 are all made of ferritic stainless steel, which effectively prevents exhaust corrosion of the flue pipes.

[0021] Specifically, a noise reduction structure is installed inside the heat conduction pipe 13. Since the flue of the heat conduction pipe 13 is relatively long, a noise reduction structure is added to reduce noise.

[0022] Specifically, the commutator 3 is an electromagnetic directional valve. The driver can control the electromagnetic directional valve from the cab by pressing a button to switch the pipeline to the heat-conducting pipeline 13 to clear snow or to the noise-reducing pipeline 12 to reduce the length of the exhaust and reduce noise.

[0023] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
