Description

  The present invention relates to a small asphalt finisher in which a driver's seat is arranged on a screed. The present invention relates to a device for preventing a driver who operates a finisher from inhaling.

  The asphalt component, which is the main component of the asphalt mixture used for asphalt pavement, includes toxic components such as carcinogenicity. In particular, when asphalt pavement is performed, the asphalt mixture rises to about 150 ° C., and a part of the asphalt component becomes oil smoke and drifts in front of the screed.

  FIG. 3 is a side view of a conventional small asphalt finisher 11. The driver sitting in the driver's seat 10 directly confirms the state of the asphalt mixture 6 and confirms the amount of the asphalt mixture 6 held in the front part of the screed 5 (between the screed 5 and the main body 12). However, it is necessary to adjust the speed of the conveyor and the screw and to proceed the paving work. Therefore, as shown in FIG. 3, the main body 12 of the small asphalt finisher 11 has a space below the control box 13 and the driving console 14 so that the driver can send a line of sight to the front of the screed 5. It is. Accordingly, the driver can perform the paving work while visually checking the state of the asphalt mixture 6 in the front portion of the screed 5. The control box 13 is used for controlling the engine and various actuators, but the control box 13 is also arranged at the top of the main body 12 as much as possible so that the driver's view is not blocked by the control box 13. Has been.

  Since the driver's seat 10 is disposed on the screed 5, the driver has a high possibility of directly sucking oil smoke. However, conventionally, an oil smoke discharge device that can be used in a large asphalt finisher has been developed, but an oil smoke discharge device that can be applied to a small asphalt finisher has not been developed.

  Patent Documents 1 and 2 disclose an example of a large asphalt finisher oil smoke discharge device. In these known techniques, the driver's seat is arranged at the top of the asphalt finisher body. Therefore, these known techniques cannot be applied as they are to the small asphalt finisher 1 in which the space between the rear portion of the main body 12 and the screed 5 is narrow. In these known technologies, since the intake port is provided between the rear portion of the main body and the screed, if the structure of the known technology is applied to a small asphalt finisher as it is, the driver can reduce the amount of asphalt mixture. It cannot be visually recognized, which hinders operation. Therefore, the oil smoke discharge device developed for a large asphalt finisher cannot be applied to a small asphalt finisher as it is.

  Therefore, there has been a demand for an invention for an oil smoke discharger that can be used for a small asphalt finisher.

  In addition, asphalt finishers are machines that prioritize work functions, so the traveling speed is slow, and it takes too much time to self-travel to the pavement site where pavement construction is performed, so it is generally carried on a trailer. When mounted on a trailer, the mounting height must be 3.8 m or less, and there are also places where the height limit is lower in the field situation. If it exceeds 3.8m, there will be a period of hitting structures such as footbridges on the road, which will cause damage. The trailer platform height is 1 m or more, and the height of the exhaust duct must be taken into consideration. However, in the known techniques such as Patent Documents 1 and 2, in order to prevent the driver from inhaling the oil smoke Since the height of the tip of the exhaust duct has to be increased, the exhaust duct must be folded when the trailer is mounted. If the folding is forgotten, it will interfere with the structure on the road, so such risks are inherent in the known technology. Furthermore, there is almost no space in the main body of the small asphalt finisher to install smoke exhaust ducts and exhaust fans. If these are forcibly installed in the main body, the operability and maintenance of other equipment will be improved. Will interfere.

  Based on the above, the present invention aims to provide an oil and smoke discharge device suitable for a small asphalt finisher, and is configured not to exceed the mounting height limit particularly when the small asphalt finisher is mounted on a trailer. It is an object of the present invention to provide an oil and smoke discharge device that does not affect the operability and maintainability of other equipment of the main body of the small asphalt finisher. This aims to prevent the driver from inhaling toxic fumes.

In order to solve the above problems, the present invention has the following features. In the present invention, the driver's seat is disposed on a screed separate from the main body, and the asphalt mixture between the screed and the main body is attached to a small asphalt finisher that is operated while the driver directly recognizes the asphalt mixture from the driver's seat. An oil smoke discharge device that is at least part of the lower part of the operation console and / or control box provided in the main body of the small asphalt finisher and does not hinder the visibility of the asphalt mixture by the driver sitting in the driver's seat A suction portion disposed at a position; an exhaust fan portion for discharging oil smoke in the suction portion; and an exhaust duct portion attached to the exhaust fan portion. The exhaust duct portion is arranged on the right side and / or the left side of the vehicle body of the small asphalt finisher. In one embodiment, the suction part is horizontally long and is disposed under the operation console or the control box, and the driver checks the amount of asphalt mixture between the screed and the suction part. so as to be able to work, that have space is provided. The exhaust fan part is provided at both ends of the suction part. The exhaust duct portions are arranged on both the right side and the left side of the vehicle body. Moreover, this invention is a small asphalt finisher which equips the said smoke discharge apparatus and makes the ground height of an exhaust duct part 2.6 m or less.

  According to the present invention, the driver can directly see the asphalt mixture by disposing the suction portion at least at a part of the lower part of the operation console and / or the control box. If arranged in this way, it does not interfere with the operation of the operation console and the control box, and it is not necessary to provide an oil smoke discharge device in the main body, so it does not affect the arrangement of the engine and various actuators. Therefore, it does not affect the operability and maintainability of other devices of the main unit. And if an exhaust duct part is arrange | positioned on the right side and / or left side of a vehicle body, since oil smoke can be discharged | emitted to the right side and / or left side of a vehicle body, the suction | inhalation by a driver | operator can be prevented. Further, if the exhaust duct part is arranged on the right side and / or the left side of the vehicle body, it is not necessary to raise the chimney as in the known art. Therefore, the height of the exhaust duct part can be reduced, and a small asphalt finisher can be attached to the trailer. It can be configured so as not to exceed the mounting height limit when mounted on. If the ground height of the small finisher is 2.6 m or less, it can be transported on a trailer.

  These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

FIG. 1 is a side view of a small asphalt finisher 1 according to an embodiment of the present invention. FIG. 2 is a rear view of the small asphalt finisher 1. FIG. 3 is a side view of a conventional small asphalt finisher 11.

  FIG. 1 is a side view of a small asphalt finisher 1 according to an embodiment of the present invention. FIG. 2 is a rear view of the small asphalt finisher 1. The small asphalt finisher 1 includes a vehicle body 2 including an engine and various actuators, a control box 3 for operating various actuators, a driving console 4 including a handle, a screed 5, and a suction unit 7. And an exhaust duct portion 8, an exhaust fan portion 9, a driver's seat 10, and wheels 17. The suction part 7, the exhaust duct part 8, and the exhaust fan part 9 serve as an oil smoke discharge device. As in the prior art, the driver's seat 10 is disposed on the screed 5. The driver performs the paving work by operating the operation console 4 while directly viewing the asphalt mixture 6 between the screed 5 and the main body 2.

  As shown in FIG. 2, the suction portion 7 is disposed below the operation console 4 and the control box 3 at a position that does not hinder the asphalt mixture 6 from being visually recognized by the driver. In consideration of the fact that the structure of the small asphalt finisher varies depending on the model, in the present invention, the suction portion 7 does not have to interfere with the visual recognition of the asphalt mixture 6 by the driver. Suppose that it may be provided only in the lower part of the driving console 4 or may be provided only in the lower part of the control box 3. For example, when it is provided only at the lower part of the operation console 4 (or at least a part thereof), the lateral width of the suction part 7 is shorter than that in the example of FIG. Further, in the case where it is provided only at the lower part (or at least part of it) of the control box 3, the suction part 7 may be divided into right and left unlike the example of FIG. In addition, the suction portion 7 may be arranged in an appropriate structure according to the structure of the small asphalt finisher. However, the suction portion 7 may be arranged in the driver's cab 4 and / or any specific structure. It is provided in at least a part of the lower part of the control box 3.

  The suction part 7 shown in FIG. 2 has a horizontally long structure that fits within the width of the main body 1. For example, the suction part 7 is a rectangular parallelepiped shape, and the lower surface is opened. The lateral width of the suction part 7 may be slightly larger than the lateral width of the main body 1.

  The exhaust fan unit 9 is a fan for discharging the oil smoke in the suction unit 7. The exhaust fan unit 9 shown in FIG. 2 is provided at both ends of the suction unit 7. Although the exhaust duct part 8 is attached to each exhaust fan part 9, the attachment position of the exhaust fan part 9 is not specifically limited. In FIG. 2, the exhaust duct portion 8 is disposed on the right side and the left side of the main body 1. As shown in FIG. 1, the upper end portion of the exhaust duct portion 8 is inclined upward and upward so that the exhausted oil smoke is not applied to a driver, a worker on the roadside, a passerby or the like. The fan of the exhaust fan unit 9 rotates, and the oil smoke in the suction unit 7 is sucked and discharged through the exhaust duct unit 8 diagonally forward and upward. The exhaust duct portion 8 has a ground height (height from the ground to the highest portion) of 2.6 m or less. As a result, the ground height of the entire small finisher 1 is 2.6 m or less, so even if it is placed on the trailer loading platform, the mounting height is 3.8 m or less, and transport on the trailer is also possible.

  In FIG. 1 and FIG. 2, two exhaust fan portions 9 and two exhaust duct portions 8 are provided on the left and right. However, if the exhaust amount of the fans is sufficient, only the right or left side of the vehicle body is provided. The exhaust fan unit 9 and the exhaust duct unit 8 may be provided.

  In this way, the suction portion 7 is disposed at least at a part of the lower part of the operation console 4 and / or the control box 3 so as not to hinder the visual recognition of the asphalt mixture 6 by the driver. As shown in FIG. 5, a space can be provided between the suction portion 7 and the asphalt mixture 6, and the driver can directly view the asphalt mixture 6 from there. Therefore, the driver can perform the paving work in the same manner as the conventional small asphalt finisher. Further, by providing the suction portion 7 at least at a part of the lower part of the operation console 4 and / or the control box 3, the operation of the operation operation table 4 and the operation of the control box 3 are not obstructed, and oil smoke is discharged. Since it is not necessary to provide the device in the main body 1, the engine and the various actuators may remain in the conventional arrangement. Therefore, the operability and maintainability of other devices of the main body are not affected. And by arrange | positioning the exhaust duct part 8 to the right side and / or left side of a vehicle body, since oil smoke can be discharged | emitted to the right side and / or left side of a vehicle body, it can prevent a driver | operator from inhaling. For example, as in the prior art, when an oil smoke chimney is placed in front of the driver, the chimney must be raised to prevent the oil smoke from reaching the driver. However, by arranging the exhaust duct portion 8 on the right side and / or the left side as in the present invention, it is possible to prevent oil smoke from being applied to the driver. Therefore, as shown in FIG. 1, the height of the exhaust duct portion 8 can be reduced. As a result, when the small asphalt finisher 1 is mounted on the trailer, it can be configured not to exceed the mounting height limit.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.
