[0026] In order to keep the following description of the embodiment of the present application clear and simple, the present application omits the detailed description of known functions and known components.

[0027] Reference is made to Figures 1 to 4The utility model embodiment provides a kind of smoke collection device for paver, including multiple smoke collecting mechanisms 1, still including adjusting device 2, the smoke collecting mechanism 1 is connected with pipeline 3, each The length of pipeline 3 connected by the smoke collecting mechanism 1 is different, the smoke collecting mechanism 1 is connected adjusting device 2 by pipeline 3 respectively, the adjusting device 2 has smoke exhaust port, and adjusting device 2's smoke exhaust port is communicated with smoke fan 4, the adjusting device 2 is used to adjust the flow of each pipeline 3.This device adjusts the flow of each pipeline 3 by adjusting device 1, to distribute the smoke flow of smoke fan 4, to provide each smoke collecting mechanism 1 with enough suction efficiency, avoid the problem that some smoke collecting mechanisms 1 suction efficiency is not good due to the length difference of pipeline 3, help to protect the health of paver operator.

[0028] Specific adjusting device 2 can be configured as follows.The adjusting 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 smoke fan 4, a plurality of through holes 22 for connecting the pipeline 3 are formed in the side wall of the cylinder 21, and a plurality of airflow channels connected to the air inlet end of the smoke fan 4 are formed in the cylinder 21, and each airflow channel is connected to one 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 smoke fan 4, the caliber control mechanism includes a plurality of partitions 24, the partitions 24 are vertically arranged in the cylinder 21, and the airflow channel is formed between the adjacent partitions 24 and the inner wall of the cylinder 21. The flow of each pipeline 3 is controlled by the airflow channel, and the size of the area of the end of the airflow channel connected to the air inlet end of the smoke fan 4 directly affects the flow of the pipeline 3. When the airflow channel corresponding to one of the pipelines 3 is smaller, the flow of the pipeline 3 through the airflow channel will be smaller, thereby achieving the flow control of each pipeline 3. Generally, the required flow of each pipeline is relatively fixed after experimental determination, so the partitions 24 can be fixed, the airflow channel is connected to the air inlet end of the smoke fan 4 with a fixed end area, and the smoke suction demand of most working conditions can be met.

[0030] To be able to respond to special use scenarios, the caliber control mechanism can be configured in the following manner to adjust the area of the airflow channel connected to the air inlet end of the smoke fan 4 according to actual needs.

[0031] The caliber control mechanism includes a plurality of partitions 24, the partitions 24 are vertically arranged in the cylinder 21, one end of the partition 24 abuts against the inner wall of the cylinder 21 between adjacent through holes 22, and the other end of the partition 24 is movably connected to the end of the other partition 24 away from the inner wall of the cylinder 21, the airflow channel is formed between the adjacent partitions 24 and the inner wall of the cylinder 21, and at least one partition 24 is fixedly connected to the inner wall of the cylinder 21. Figure 3The angle between the two partitions 24 affects the cross section of the airflow passage to the suction fan 4, and thus affects the flow rate of each pipe 3. The angle between the two partitions 24 can be changed by moving the partitions 24, so that the flow rate of each pipe 3 can be easily adjusted.

[0032] To further simplify the adjustment operation, a sliding groove 25 is formed in the wall of the cylinder 21 between the adjacent through holes 22. The sliding groove 25 is parallel to the end of the cylinder 21. One end of the partition 24 close to the inner wall of the cylinder 21 is fixedly connected to the operating screw 26, and the operating screw 26 extends out of the sliding groove 25. The operating screw 26 extends out of the sliding groove 25, so that the partition 24 can be directly controlled by the operating screw 26 during the adjustment operation. The flow rate of each pipe 3 can be adjusted without disassembling the adjustment device 2.

[0033] A slot cover 23 is installed on the operating screw 26. The extending end of the operating screw 26 is screwed into a nut that fixes the slot cover 23. The slot cover 23 is used to cover the sliding groove 25. The slot cover 23 covers the sliding groove 25, reducing air leakage in the airflow passage and reducing the suction loss of the suction fan 4. When the operating screw 26 is moved to the position as shown in Figure 2 The slot cover 23 can be rotated 180 degrees to cover the sliding groove 25 by loosening the nut, and then tightened to fix it. There is a sealing element between the slot cover 23 and the cylinder 21, which can seal the gas from leaking out. The sealing element can be a rubber strip arranged along the edge of the slot cover 23.

[0034] The smoke collecting mechanism 1 includes a cover 11, and the cover 11 is provided with a recess 12 connected to the pipe 3. In use, the recess 12 connects the pipe 3, and the recess 12 is the center of negative pressure, so that the smoke in other parts of the cover 11 can naturally flow into the recess 12, which helps to improve the smoke suction efficiency of the smoke collecting mechanism 1.

[0035] An extension 13 for guiding smoke into the cover 11 is installed on one side of the cover 11. One end of the extension 13 is connected to the edge of the cover 11. The extension 13 expands the coverage of the cover 11, allowing more smoke to enter the cover 11 and improving the smoke suction efficiency of the smoke collecting mechanism 1. The extension 13 is inclined to guide the smoke into the cover 11.

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

[0037] A paving machine is provided with the smoke collecting device as described above. The smoke collecting device uses the smoke exhaust mechanism to exhaust smoke outside the operating position of the paving machine operator, protecting the health of the paving machine operator.
