[0026] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0027] See also Figures 1 to 4The embodiment of the present invention provides a smoke collection device for a paving machine, including a plurality of smoke collecting mechanisms 1 and an adjusting device 2. The smoke collecting mechanisms 1 are all connected to a pipe 3. The pipe 3 connected to each of the smoke collecting mechanisms 1 has a different length. The smoke collecting mechanisms 1 are respectively connected to the adjusting device 2 through the pipe 3. The adjusting device 2 has a smoke exhaust port, and the smoke exhaust port of the adjusting device 2 is connected to a smoke exhaust fan 4. The adjusting device 2 is used to adjust the flow of each pipe 3. The device adjusts the flow of each pipe 3 through the adjusting device 1, thereby allocating the smoke flow of the smoke exhaust fan 4, so as to provide sufficient suction efficiency for each smoke collecting mechanism 1, avoiding the problem that the smoke collection efficiency of some smoke collecting mechanisms 1 is poor due to the different lengths of the pipes 3 of the smoke collecting mechanisms 1, and helping to protect the health of the operators of the paving machine.

[0028] The specific regulating device 2 can be constructed as follows. The regulating device 2 includes a cylinder 21, one end of the cylinder 21 is closed, and the other end of the cylinder 21 is connected to the air inlet end of the smoking fan 4, a plurality of through holes 22 for connecting the pipeline 3 are opened on the side wall of the cylinder 21, and a plurality of air flow channels connected to the air inlet end of the smoking fan 4 are constructed in the cylinder 21, and each of the air flow channels is connected to a through hole 22.

[0029] The cylinder 21 is provided with a caliber control mechanism, which is used to control the area of ​​the end of the airflow channel connected to the air inlet end of the smoking fan 4. The caliber control mechanism includes a plurality of baffles 24, which are vertically arranged in the cylinder 21, and an airflow channel is formed between the adjacent baffles 24 and the inner wall of the cylinder 21. The flow of each pipeline 3 is controlled by the airflow channel, and the area of ​​the end of the airflow channel connected to the air inlet end of the smoking fan 4 directly affects the flow of the pipeline 3. When the airflow channel corresponding to one of the pipelines 3 is small, the flow of the pipeline 3 flowing through the airflow channel will become smaller, thereby realizing the flow control of each pipeline 3. In general, after experimental determination, the required flow corresponding to each pipeline is relatively fixed, so the baffle 24 can be fixed, and the airflow channel is connected to the air inlet end of the smoking fan 4 with a fixed end area, which can meet the smoking needs of most working conditions.

[0030] In order to cope with special usage scenarios, the caliber control mechanism can be constructed in the following manner to be able to adjust the area of ​​the air flow channel connecting the air inlet end of the smoking fan 4 according to actual needs.

[0031] The caliber control mechanism includes a plurality of baffles 24, which are vertically arranged in the cylinder 21, one end of the baffle 24 abuts against the inner wall of the cylinder 21 between adjacent through holes 22, and the other end of the baffle 24 is movably connected to the end of other baffles 24 away from the inner wall of the cylinder 21, and an air flow channel is formed between adjacent baffles 24 and the inner wall of the cylinder 21, and at least one baffle 24 is fixedly connected to the inner wall of the cylinder 21. Figure 3When in use, the angle between the two partitions 24 affects the cross-sectional size of the airflow channel connecting the smoking fan 4, thereby affecting the flow of each pipeline 3. By moving the partition 24, the angle between the partitions 24 can be changed, and the flow of each pipeline 3 can be easily adjusted.

[0032] To further simplify the adjustment operation, a slide groove 25 is provided on the cylinder wall of the cylinder 21 between the adjacent through holes 22, and the slide groove 25 is arranged parallel to the end of the cylinder 21. The end of the partition 24 not fixedly connected to the inner wall of the cylinder 21 close to the inner wall of the cylinder 21 is fixedly connected to an operating screw 26, and the operating screw 26 extends from the slide groove 25. By extending the operating screw 26 from the slide groove 25, the movement of the partition 24 can be directly controlled by the operating screw 26 during the adjustment operation, and the flow of each pipeline 3 can be adjusted without disassembling the adjustment device 2.

[0033] The operating screw 26 is provided with a slot cover 23, and the extended end of the operating screw 26 is screwed into a nut for fixing the slot cover 23, and the slot cover 23 is used to cover the chute 25. The slot cover 23 covers the chute 25, reduces air leakage in the air flow channel, and reduces the suction loss of the smoking fan 4. Figure 2 In the position shown, the chute 25 is exposed, and the nut can be loosened to rotate the slot cover 23 180 degrees to cover the chute 25, and then the nut can be tightened to fix it. There is a seal between the slot cover 23 and the cylinder 21 to seal the gas from leaking out. The seal can be a rubber strip arranged along the edge of the slot cover 23.

[0034] The smoke collecting mechanism 1 comprises a cover 11, on which a recessed portion 12 is provided, and the recessed portion 12 is connected to the pipe 3. When in use, the recessed portion 12 is connected to the pipe 3, and the recessed portion 12 is a negative pressure center, so that smoke from other parts under the cover 11 can naturally gather and flow into the recessed portion 12, which helps to improve the smoke absorption efficiency of the smoke collecting mechanism 1.

[0035] An extension portion 13 for guiding smoke into the cover 11 is installed on one side of the cover 11, and one end of the extension portion 13 is connected to the edge of the cover 11. The extension portion 13 expands the coverage of the cover 11, allowing smoke in a larger range to enter the cover 11, thereby improving the smoke absorption efficiency of the smoke collection mechanism 1. The extension portion 13 is arranged obliquely to guide smoke into the cover 11.

[0036] The air outlet end of the smoke exhaust fan 4 is connected to the smoke exhaust mechanism.

[0037] A paver is equipped with the above-mentioned smoke collecting device. The smoke collecting device uses a smoke exhaust mechanism to exhaust smoke outside the operating position of the paver operator to protect the health of the paver operator.

[0038] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
