[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figures 1 to 3The illustrated dustproof device for a sidewalk tiered chain includes a first mounting frame 1, a second mounting frame 14 mounted on the upper side of the first mounting frame 1, and a dust removal assembly between the first mounting frame 1 and the second mounting frame 14. The dust removal assembly includes a cleaning roller 16, an electric motor 18, a suction head 2, a connecting pipe 21, a connector 22, a suction hose 23, and a vacuum cleaner 24. The cleaning roller 16 is rotatably connected to the inner sides of both the first mounting frame 1 and the second mounting frame 14, and equipment is fixedly connected to the left ends of both the first mounting frame 1 and the second mounting frame 14. The housing 17 has two sets of equipment housings 17, each with an electric motor 18 fixedly installed inside. The output ends of the two sets of electric motors 18 are fixedly connected to the left ends of the two sets of dust removal rollers 16 respectively. The first mounting bracket 1 has a dust collection head 2 fixedly connected to the right end of both the front and rear sides. The left end of the connecting pipe 21 is fixedly connected to the right side of the two sets of dust collection heads 2 respectively. The connector 22 is fixedly connected to the right end of the connecting pipe 21. The left end of the dust collection hose 23 is fixedly connected to the connector 22. The right end of the dust collection hose 23 is fixedly connected to the dust collection port of the vacuum cleaner 24.

[0030] The first mounting bracket 1 and the second mounting bracket 14 are respectively installed on the lower and upper sides of the chain, so that the brush on the surface of the dust removal roller 16 contacts the chain. During use, the two sets of electric motors 18 drive the dust removal rollers 16 on the upper and lower sides to rotate, and the two sets of dust removal rollers 16 rotate in opposite directions to remove dust from the surface of the chain, effectively preventing dust from accumulating on the surface of the chain, thereby improving the stability of chain operation and the safety of equipment use. At the same time, during the dust removal process of the dust removal roller 16, the vacuum cleaner 24 is started. The vacuum cleaner 24 sucks up the dust generated by the cleaning through the vacuum hose 23, the connecting pipe 21 and the vacuum head 2, preventing dust from falling back onto the chain surface and further improving the dustproof effect of the chain.

[0031] See Figure 2 Two sets of support blocks 11 are fixedly connected to the upper right side of the first mounting bracket 1. The upper ends of the two sets of support blocks 11 are fixedly connected to the fixing screws 12. The surface of the fixing screws 12 is threaded with locking nuts 13. Two sets of positioning sleeves 15 are fixedly connected to the upper and lower sides of the right end of the second mounting bracket 14. The four sets of positioning sleeves 15 are respectively fitted onto the surface of the two sets of fixing screws 12. The lower end of the lower positioning sleeve 15 abuts against the surface of the support block 11.

[0032] In addition, during the installation of the two sets of cleaning rollers 16, the first mounting bracket 1 is first fixed on the lower side of the chain, and the brush on the surface of the lower cleaning roller 16 is brought into contact with the lower side of the chain. Then, the second mounting bracket 14 is placed on the upper side of the chain. Next, the four sets of positioning sleeves 15 on the right side are respectively fitted onto the surfaces of the two sets of fixing screws 12. Then, the locking nuts 13 are respectively threaded to the upper ends of the two sets of fixing screws 12 to lock and fix the second mounting bracket 14.

[0033] See Figure 1 , Figure 3 and Figure 4 The first mounting bracket 1 is fixedly connected to the right end of the first support bracket 3. The inner side of the first support bracket 3 is slidably connected to the second support bracket 3. The right end of the second support bracket 33 is fixedly connected to the fixing seat 36. The inner walls of the front and rear sides of the first support bracket 3 are fixedly connected to two sets of limiting rods 31. The front and rear surfaces of the first support bracket 3 are provided with first connecting holes 32 near the right end. The front and rear surfaces of the second support bracket 33 are provided with two sets of limiting grooves 34. The limiting rods 31 are slidably connected to the limiting grooves 34. The surface of the second support bracket 33 is provided with multiple sets of longitudinal second connecting holes 35.

[0034] Meanwhile, during the installation of the first mounting bracket 1, the first mounting bracket 1 is first placed on the underside of the chain. Then, the second support bracket 33 is slid to the right so that the fixing seat 36 is tightly pressed against the surface of the equipment bracket. Then, the fixing seat 36 is fixed to the surface of the equipment bracket with screws. Then, bolts are machined and passed through the first connecting hole 32 and the second connecting hole 35 to lock and fix the first support bracket 3 and the second support bracket 33, thereby stably fixing the first mounting bracket 1 on the underside of the chain. In addition, since the distance between the chain and the equipment bracket is different in different equipment, the first support bracket 3 and the second support bracket 33 can be used in combination to use equipment brackets with different distances, thereby improving the adaptability of the equipment.

[0035] The working principle of this utility model is as follows: The electric motor 18 drives the dust removal roller 16 to rotate, which cleans the surface of the chain, effectively preventing dust from accumulating on the chain surface and improving the stability and safety of the equipment operation. At the same time, the vacuum cleaner 24, in conjunction with the vacuum head 2, sucks up the dust generated during cleaning, preventing the dust from spreading and falling back onto the chain surface, further improving the dustproof effect of the equipment. Meanwhile, the limiting rod 31 and the limiting groove 34 cooperate to allow the first support frame 3 to slide left and right inside the second support frame 33, adjusting the left and right position of the dust removal component and improving the adaptability of the dust removal component to installation conditions.
