[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, a dual-axis motor is used to drive two connecting shafts to rotate, and the connecting shafts then drive the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first gear to rotate, and the first gear then drives the second gear to rotate, so that the second rotating shaft also starts to rotate, and then drives the third gear at its end to rotate.

This design can further improve the dust cleaning ability of the device.

[0044] like Figure 1 and Figure 2 As shown, two mounting seats 1 are also included. First mounting holes 2 are opened at the four corners of the tops of the two mounting seats 1. The tops of the two mounting seats 1 are fixedly connected to the two ends of the track 3 respectively.

[0045] like Figure 1 and Figure 2 As shown, the bottom of the two rails 3 are fixedly connected with brackets 7, and the two side walls of the two brackets 7 are fixedly connected with inclined support plates 8. The ends of the inclined support plates 8 are respectively fixedly connected to the mounting base 1. The inclined support plates firmly connect the brackets and the mounting base together to form a stable triangular support structure, which further improves the stability of the entire device, can prevent the rails from breaking, and play a protective role.

[0046] like Figure 3 and Figure 4 As shown, a chassis 9 is fixedly connected between the two mounting frames 20 , two connecting shafts 10 are provided on the inner wall of the chassis 9 , both ends of the connecting shafts 10 are fixedly connected to the corresponding first rotating shafts 23 , and a fixing seat 11 is fixedly connected to the top of the inner wall of the chassis 9 .

[0047] like Figure 3 and Figure 4 As shown, the inner wall of the chassis 9 is rotatably connected to two drive shafts 14, and the circumferential outer walls of the two drive shafts 14 are fixedly connected with synchronous wheels 151, and the two synchronous wheels 151 are connected by a synchronous belt transmission, the outer wall of the fixed seat 11 is fixedly connected to a double-axis motor 16, and the two ends of the two double-axis motors 16 are respectively fixedly connected to the corresponding connecting shafts 10, and the circumferential outer walls of the two drive shafts 14 are fixedly connected to a winding disk 15, the bottom of the chassis 9 is fixedly connected to a frame 18, the outer wall of the frame 18 is fixedly connected to a single-axis motor 19, and the output end of the single-axis motor 19 is fixedly connected to one of the drive shafts 14, and a second mounting hole 12 is opened at the bottom of the chassis 9, and two baffles 17 are fixedly connected to the bottom of the chassis 9, and a conveying roller 13 is rotatably connected between the two baffles 17 and the inner wall of the second mounting hole 12.

[0048] Working principle: The two connecting shafts 10 are driven to rotate by the dual-axis motor 16, and the connecting shaft 10 then drives the first rotating shaft 23 to rotate. The rotation of the first rotating shaft 23 drives the first gear 24 to rotate. The first gear 24 then drives the second gear 26 to rotate, so that the second rotating shaft 25 also starts to rotate, and then drives the third gear 39 at its end to rotate. The two third gears 39 respectively drive the output shaft 37 to rotate, and finally drive the cleaning roller 38 to rotate.

[0049] At the same time, the first gear 24 meshes with the toothed plate 5 . When the first gear 24 rotates, it drives the mounting frame 20 to slide along the outer wall of the track 3 . The movement of the mounting frame 20 causes the slide plate 21 to slide along the inner wall of the slide groove 6 .

[0052] As the plug rod 34 slides back and forth, the piston 33 is also driven to perform corresponding reciprocating motion in the gas tank 32.
