[0023] Embodiment one: as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides a kind of working vehicle smoke exhaust mechanism, including disc 1, disc 1 is set to vertical state, the outer wall of disc 1 is fixedly installed with external support 2, the bottom of external support 2 is fixedly connected with bottom disc 3, the inside of disc 1 is rotatably installed with rotating block 4, rotating block 4 is provided with smoke exhaust pipe 5, smoke exhaust pipe 5 is in the form of vortex and is wound on the outer wall of rotating block 4, one end of smoke exhaust pipe 5 is fixedly communicated with butt joint end 6, the other end of smoke exhaust pipe 5 is fixedly communicated with discharge end 7, both ends of smoke exhaust pipe 5 are all through the edge of disc 1, butt joint end 6 and discharge end 7 are distributed along the center of disc 1 symmetry;

[0024] Cavity 8 is opened in the inside of disc 1, rotating block 4 is located in the inside of cavity 8, one end of rotating block 4 is rotatably connected on one side of disc 1, the other end of rotating block 4 is fixedly connected with filling plate 12, filling plate 12 is rotatably installed on the other side of disc 1, and smoke exhaust pipe 5 is located between filling plate 12 and disc 1.

[0025] The specific settings and effects of the embodiment are described as follows. One end of the rotating block 4 is rotatably connected to one side of the disc 1. The disc 1 has a cavity 8 formed therein to accommodate the rotating block 4 and the smoke exhaust pipe 5 on the outer wall thereof. The smoke exhaust pipe 5 is wound in a vortex shape on the outer wall of the rotating block 4 and penetrates through the disc 1 at both ends. In use, the bottom disc 3 facilitates the movement of the device by the operator. The disc 1 is fixedly connected between the external support 2 and the bottom disc 3 and is in a fixed state and cannot rotate. After the device is moved to the vicinity of the working vehicle, the butt joint end 6 is connected to the exhaust pipe of the working vehicle, and the discharge end 7 is connected to the external air extraction device, so that the dense smoke generated when the working vehicle is started is discharged to the external environment, thereby avoiding the pollution of the air in the vicinity of the working vehicle.

[0026] The filling plate 12 at the other end of the rotating block 4 is rotatably connected to the other side of the disc 1, so as to ensure the stability of the rotating block 4. At the same time, the filling plate 12 seals the disc 1, so as to prevent the smoke exhaust pipe 5 from falling off from the disc 1 and ensure the stability of the smoke exhaust pipe 5 in the disc 1.

[0027] As shown in Embodiment Two, Figure 3 and Figure 4 the rotating block 4 has a strip-shaped hole 10 formed therein. The strip-shaped hole 10 penetrates through the rotating block 4. The middle part of the smoke exhaust pipe 5 is located in the strip-shaped hole 10. The strip-shaped hole 10 has a blocking block 9 arranged at each side thereof. The corner of the blocking block 9 has an arc-shaped groove 11 formed therein. The smoke exhaust pipe 5 is overlapped on the groove wall of the arc-shaped groove 11. One side of the filling plate 12 is fixedly provided with a protruding block 13.

[0028] The effects achieved by the entire embodiment are as follows. The strip-shaped hole 10 is used to accommodate the smoke exhaust pipe 5. The middle part of the smoke exhaust pipe 5 is arranged in the strip-shaped hole 10. The two ends of the pipe extend out from the two ends of the strip-shaped hole 10 and are wound on the outer wall of the rotating block 4. The presence of the blocking block 9 can determine the position of the smoke exhaust pipe 5. The arc-shaped groove 11 at the corner of the blocking block 9 can avoid excessive friction with the smoke exhaust pipe 5 when the smoke exhaust pipe 5 is extracted, thereby protecting the smoke exhaust pipe 5. After the smoke exhaust pipe 5 is used, the protruding block 13 is rotated to drive the rotating block 4, so as to collect the smoke exhaust pipe 5 back into the disc 1.

[0029] The use method and working principle of the device are as follows. In use, the device is moved to the vicinity of the working vehicle. Then, the butt joint end 6 is connected to the exhaust pipe of the working vehicle, and the discharge end 7 is connected to the external air extraction device, so that the dense smoke generated when the working vehicle is started is discharged to the external environment. In the process of connecting the exhaust pipe of the working vehicle, the smoke exhaust pipe 5 can be extracted from the disc 1. Since the disc 1 is fixedly connected between the external support 2 and the bottom disc 3 and is in a fixed state and cannot rotate, the rotating block 4 is driven when the smoke exhaust pipe 5 is extracted.

[0030] The smoke exhaust pipe 5 is spirally wound on the outer wall of the rotating block 4, and the filling plate 12 at the other end of the rotating block 4 seals the disc 1, preventing the smoke exhaust pipe 5 from falling off the disc 1; the rotating block 4 is internally provided with a strip-shaped hole 10 for accommodating the smoke exhaust pipe 5, the middle section of the smoke exhaust pipe 5 is arranged in the strip-shaped hole 10, and the two ends of the pipe extend out of the two ends of the strip-shaped hole 10 respectively; and the blocking block 9 can determine the position of the smoke exhaust pipe 5;

[0031] After the smoke exhaust pipe 5 is used, the rotating block 4 is rotated by the rotating lug 13, and the smoke exhaust pipe 5 is retracted into the disc 1.

[0032] The above is only the preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the protection scope of the technical scheme of the present application.
