[0020] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0021] Reference Figure 1 - Figure 4 A construction dust suppressor comprises a No. 1 cylinder body 1 and a No. 2 cylinder body 2 installed at the front end of the No. 1 cylinder body 1, a No. 1 flange 3 is installed on the No. 1 cylinder body 1, a No. 2 flange 4 is fixed on the No. 2 cylinder body 2, and a clamping mechanism for facilitating the installation and disassembly of the No. 1 cylinder body 1 and the No. 2 cylinder body 2 is provided between the No. 1 flange 3 and the No. 2 flange 4; the clamping mechanism comprises a locating pin 5 fixed on the No. 2 flange 4 and a clamping groove 6 provided on the locating pin 5, and a No. 1 clamping block 7 arranged between the locating pin 5 and the clamping groove 6, and also comprises a plurality of No. 2 clamping blocks 10 circumferentially distributed on the outer ring of the No. 1 flange 3.

[0022] Reference Figure 3 - Figure 4 A positioning hole 12 is formed through the No. 1 flange 3, and the positioning pin 5 is plugged into the positioning hole 12. After the plugging, the card slot 6 completely penetrates the No. 1 flange 3. Through axial plugging, the mounting holes on the No. 1 flange 3 and the No. 2 flange 4 are accurately positioned for easy connection.

[0023] Reference Figure 4 The No. 1 block 7 is elastically connected to the positioning pin 5 through the No. 1 spring 8. The priority contact surface between the No. 1 block 7 and the No. 2 block 10 is inclined. A linkage ring 9 is rotatably arranged outside the No. 1 flange 3. Multiple No. 2 blocks 10 are fixed on the linkage ring 9. The linkage ring 9 can connect multiple No. 2 blocks 10 at the same time. The increase in the number of No. 2 blocks 10 improves the predetermined structural stability of the No. 1 cylinder 1 and the No. 2 cylinder 2 before being locked by bolts.

[0024] Reference Figure 3 A No. 2 spring 11 is also provided between the linkage ring 9 and the No. 1 flange 3. The No. 2 clamping block 10 is plugged into the clamping slot 6 through the No. 2 spring 11. The No. 2 spring 11 is arranged along the circumferential direction, which can not only ensure the axial locking between the clamping slot 6 and the No. 2 clamping block 10, but also facilitate the separation of the two through axial rotation.

[0025] Reference Figure 1 - Figure 3 The No. 1 flange 3 and the No. 1 cylinder body 1 are movably connected, and a circumferentially limited locking mechanism is arranged between the No. 1 flange 3 and the No. 1 cylinder body 1, and the locking mechanism comprises a locking sleeve 13 fixed on the No. 1 flange 3 and the No. 2 flange 4 and a locking seat 14 fixed on the No. 1 cylinder body 1, and a long bolt 15, and the long bolt 15 penetrates the locking sleeve 13 and the locking seat 14 at the same time and locks them, and the rotation arrangement of the No. 1 flange 3 and the No. 1 cylinder body 1 allows the staff to tighten all the bolts without moving their positions, which has the advantage of convenient operation, and the locking mechanism can circumferentially position the No. 1 flange 3 and the No. 1 cylinder body 1, thereby ensuring the structural reliability of the dust suppressor.

[0026] Working principle: when connection is required, insert the positioning pin 5 into the positioning hole 12, and the No. 1 clamping block 7 is squeezed with the No. 2 clamping block 10. At this time, the No. 1 spring 8 is compressed, and the No. 1 clamping block 7 makes an avoidance. After the No. 2 clamping block 10 enters the inside of the clamping groove 6, the No. 1 clamping block 7 clamps the front end of the No. 2 clamping block 10 under the action of the No. 1 spring 8. At this time, the No. 1 cylinder 1 and the No. 2 cylinder 2 are pre-positioned, and the bolts between the No. 2 cylinder 2 and the No. 1 flange 3 are installed. The No. 1 flange 3 can rotate on the No. 1 cylinder 1, so the No. 1 cylinder 1 and the No. 2 cylinder 2 rotate synchronously with the No. 1 flange 3, and the bolts are locked in turn by rotation. Finally, the long bolt 15 passes through the locking sleeves 13 on the No. 1 flange 3 and the No. 2 flange 4, and then passes through the locking seat 14 and then locked;

[0027] To disassemble the No. 2 cylinder 2, remove the long bolt 15, and remove the bolts on the No. 1 flange 3 and the No. 2 flange 4 in turn by rotating. By rotating the linkage ring 9, the No. 2 spring 11 is compressed, and the No. 2 clamping block 10 is disengaged from the side of the clamping slot 6, the No. 2 cylinder 2 is removed, and the locating pin 5 is disengaged from the locating hole 12.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
