Description

Technical Field

[0001] The utility model relates to the field of exhaust mufflers, and more specifically to a large-scale mining truck exhaust muffler which is easy to disassemble. Background Art

[0002] A large mining truck is a mining truck, which is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Its working characteristics are short travel distance and heavy load. It is usually loaded with a large electric shovel or hydraulic shovel, and travels back and forth between the mining site and the unloading site. In recent years, with the rapid economic development of our neighboring countries and African countries, the demand for mining trucks has continued to grow rapidly. At the same time, the country's standards and regulations for mining trucks have been gradually improved, the outline of the standard system has gradually become clear, and the structure and content have gradually been integrated with international standards, reflecting strict requirements on safety, environmental protection, ergonomics, etc. Construction machinery manufacturers have entered the research and development of mining trucks, which has brought the development of mining trucks into a new era.

[0003] In order to avoid loud noise from the exhaust pipe of large mining trucks during use, which may cause damage to the ears of workers, the outer end of the exhaust pipe is generally fixed with an exhaust muffler by bolts. Since the working environment of large mining trucks is dusty and contains a lot of impurities, in order to avoid clogging of the exhaust muffler, the exhaust muffler needs to be disassembled and cleaned frequently. However, dust and impurities in the environment can easily clump and accumulate in the gap between the exhaust pipe and the exhaust muffler, resulting in greater friction at the connection, which makes disassembly difficult.

[0004] Therefore, a large-scale mining truck exhaust muffler which is easy to disassemble is proposed to solve some problems existing in the above-mentioned prior art. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a large-scale mining truck exhaust muffler that is easy to disassemble, which is characterized in that the driving block is driven to counteract the limit plate during the movement process by rotating the long strip plate, and then the physical principle that the action of force is mutual is used to realize the separation of the exhaust pipe and the main body, thereby facilitating the user to disassemble the exhaust muffler.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A large mining truck exhaust muffler that is easy to disassemble comprises an exhaust pipe and a main body sleeved on the left end thereof, the front and rear ends of the main body are fixedly connected with load-bearing bolts, the outer ends of the load-bearing bolts are rotatably connected with long strips, the two long strips are fixedly connected with load-bearing rods at one end away from each other, the outer ends of the load-bearing rods are provided with driving blocks, the right sides of the two load-bearing bolts are provided with limiting plates fixedly connected with the exhaust pipe, the limiting plates are matched with the driving blocks, the front and rear ends of the exhaust pipe are provided with mounting holes, and the inner parts of the mounting holes are threadedly connected with bolts matched with the long strips.

[0010] Furthermore, the driving block is rotatably connected to the bearing rod, and the driving block is configured to be cylindrical, which effectively reduces the friction between the driving block and the limiting plate, and prevents the bearing rod from moving after being subjected to force.

[0011] Furthermore, a limiting groove is provided at one end of the limiting plate close to the driving block, and the driving block is located inside the limiting groove. The limiting groove can realize the positioning of the driving block to avoid deviation during the movement of the driving block.

[0012] Furthermore, a handle is fixedly connected to one end of the long board away from the bearing bolt, and the handle is L-shaped. The handle can relatively extend the length of the long board. By using the lever principle, the user can easily rotate the long board to drive the driving block to move.

[0013] Furthermore, a water inlet pipe connected to the exhaust pipe is opened at the upper end thereof, and a filter screen is fixedly connected to the inside of the water inlet pipe. When the exhaust muffler is disassembled, the user can inject water into the exhaust pipe through the water inlet pipe to decompose the clumped dust and impurities, thereby facilitating the user to separate the exhaust pipe from the main body.

[0014] Furthermore, a bottom plate is fixedly connected to one end of the limiting plate near the exhaust pipe, and the bottom plate is located at the lower end of the long board. The bottom plate can provide support for the long board, and during installation, the user does not need to hold the long board by hand to position it.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) This solution is to drive the driving block to counteract the limit plate during the movement by rotating the long strip plate, and then use the physical principle that the force is mutual to separate the exhaust pipe and the main body, so as to facilitate the user to disassemble the exhaust muffler.

[0018] (2) By setting the driving block to be rotatably connected to the bearing rod, the friction between the driving block and the limit plate can be effectively reduced, thereby preventing the bearing rod from moving after being subjected to force. The opening of the limit groove can prevent the driving block from deflecting during movement.

[0019] (3) The setting of the handle can facilitate the user to rotate the long strip to drive the driving block to move. At the same time, the user can inject water into the exhaust pipe through the water inlet pipe to decompose the clumped dust and impurities, thereby facilitating the user to separate the exhaust pipe from the main body.

[0032] See also Figure 2 The driving block 6 is rotatably connected to the bearing rod 5. The driving block 6 is set to a cylindrical shape, which effectively reduces the friction between the driving block 6 and the limiting plate 7, and prevents the bearing rod 5 from moving after being stressed. A limiting groove 8 is provided at one end of the limiting plate 7 close to the driving block 6. The driving block 6 is located inside the limiting groove 8. The limiting groove 8 can realize the positioning of the driving block 6 to prevent the driving block 6 from being offset during the movement.

[0033] Embodiment 2:

[0034] See also Figure 1 and Figure 5 , a large-scale mining truck exhaust muffler that is easy to disassemble, a handle 13 is fixedly connected to one end of the long plate 4 away from the bearing bolt 3, and the handle 13 is set in an L shape. The handle 13 can relatively extend the length of the long plate 4. By using the principle of lever, it is convenient for the user to rotate the long plate 4 to drive the driving block 6 to move. A water inlet pipe 14 communicating with it is opened at the upper end of the exhaust pipe 1, and a filter screen is fixedly connected inside the water inlet pipe 14. When disassembling the exhaust muffler, the user can inject water into the exhaust pipe 1 through the water inlet pipe 14 to decompose the agglomerated dust and impurities, so as to facilitate the user to separate the exhaust pipe 1 from the main body 2. The limiting plate 7 is fixedly connected to a bottom plate 9 near one end of the exhaust pipe 1. The bottom plate 9 is located at the lower end of the long plate 4. The bottom plate 9 can provide support for the long plate 4. During installation, the user does not need to hold the long plate 4 by hand to position it.

[0035] When the exhaust muffler needs to be disassembled, the user first unscrews the bolt 12 from the mounting hole 10, and then rotates the long plate 4 upward to drive the driving block 6 fixedly connected thereto to move in the same direction. The driving block 6 abuts against the limit plate 7 during the movement, and the driving block 6 applies pressure to the limit plate 7. Since the force is mutual, the exhaust pipe 1 will also apply a force in the opposite direction to the main body 2, thereby making it convenient for the user to separate the exhaust pipe 1 and the main body 2, thereby facilitating the disassembly of the exhaust muffler.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
