[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] like Figures 1 to 6 As shown, the utility model provides a dust prevention system for a sweeper, comprising: a dust prevention structure 1 and a driving structure 2, wherein the dust prevention structure 1 is arranged on the side of the sweeping brush 5 of the sweeper away from the cab, and comprises a fixed water pipe 11 and a movable water pipe 12, and a sprinkler nozzle and a water mist nozzle are respectively installed on one side of the fixed water pipe 11 and the movable water pipe 12 in sequence along their respective length directions, the sprinkler nozzle corresponds to the cleaning end of the sweeping brush 5, and the movable water pipe 12 is arranged above the fixed water pipe 11; the driving structure 2 is connected to the movable water pipe 12 to drive the movable water pipe 12 to rotate back and forth, thereby driving the water mist nozzle to rotate to spray water mist.

[0026] In the present device, the dust-proof structure 1 includes a fixed water pipe 11 and a movable water pipe 12. A sprinkler nozzle is sequentially installed on one side of the fixed water pipe 11 along the length direction, and a water mist nozzle is sequentially installed on one side of the movable water pipe 12 along the length direction, so that the fixed water pipe 11 and the movable water pipe 12 can spray water and water mist through the sprinkler nozzle and the water mist nozzle respectively. The dust-proof structure 1 is arranged on the side of the cleaning brush 5 of the sweeper away from the cab, and the sprinkler nozzle corresponds to the cleaning end of the cleaning brush 5, and can sprinkle water on the cleaning end of the cleaning brush 5 during the cleaning process to reduce the dust raised during the cleaning process; the movable water pipe 12 is arranged above the fixed water pipe 11, and the driving structure 2 is connected to the movable water pipe 12, and can drive the movable water pipe 12 to rotate back and forth, driving the water mist nozzle to rotate to spray water mist, so that a large range of water mist can be sprayed behind the cleaning brush 5 during the driving of the sweeper to prevent the dust raised during the cleaning process from spreading.

[0027] It should be noted that this solution is mainly aimed at disc brush type sweepers. Therefore, the above-mentioned cleaning brush 5 is a disc brush, which is installed on the frame 7 of the sweeper through the mounting bracket 6. This solution can spray water mist behind the disc brush of the sweeper towards the disc brush and above the rear of the disc brush when the sweeper is in driving state to prevent dust from being raised or spread.

[0028] In order to facilitate the installation and disassembly of the dustproof structure 1, the driving structure 2 and the installation structure 3, as shown in FIG. Figures 1 to 4As shown, in some embodiments, the dust prevention system of the sweeper also includes a mounting plate 8, which is horizontally mounted on the frame 7 by bolts, and the bottom surface of the mounting plate 8 is in contact with the top surface of the frame 7. The driving structure 2 and the mounting structure 3 are both mounted on the mounting plate 8, and the connecting base 31 is rotatably connected to the mounting plate 8. During implementation, the mounting plate 8 serves as a mounting substrate for the driving structure 2 and the mounting structure 3. Each structure can be pre-installed on the mounting plate 8, and then the mounting plate 8 can be fixed on the frame 7. There is no need to install each structure in turn in the narrow space under the vehicle, which is convenient for installation and disassembly.

[0029] In order to facilitate the storage of the dustproof structure 1, Figures 1 to 4 As shown, in some embodiments, the dust prevention system of the sweeper also includes a mounting structure 3 and a storage and adjustment structure 4. Specifically, one end of the fixed water pipe 11 and the movable water pipe 12 are both mounted on the mounting structure 3, and the mounting structure 3 is rotatably arranged above the frame 7, so that the dust prevention structure 1 forms a working state and a storage state within the rotation range of the mounting structure 3.

[0030] When the dustproof structure 1 is in the working state, the fixed water pipe 11 and the movable water pipe 12 are perpendicular to the frame 7, and are in a state of extending from the mounting structure 3 to the outside of the frame 7. The length direction of the frame 7 is consistent with the length direction of the vehicle body. At this time, the fixed water pipe 11 and the movable water pipe 12 are horizontally arranged on the side of the cleaning brush 5 away from the cab to facilitate watering.

[0031] When the dustproof structure 1 is in the storage state, the fixed water pipe 11 and the movable water pipe 12 are arranged above the frame 7 and parallel to the frame 7. At this time, the dustproof structure 1 of the dustproof system of the sweeper can be folded and stored above the frame 7, which protects the dustproof structure 1.

[0032] In order to achieve flexible switching between the storage state and the working state, the driving end of the storage adjustment structure 4 is connected to the mounting structure 3. The storage adjustment structure 4 can drive the mounting structure 3 to rotate relative to the frame 7, thereby driving the dustproof structure 1 to switch between the storage state and the working state.

[0033] In some embodiments, the mounting structure 3 includes a connecting base 31 and a mounting base 32, the bottom end of the connecting base 31 is rotatably connected to the frame 7, the driving end of the storage and adjustment structure 4 is connected to the connecting base 31, and the mounting base 32 partially extends into the connecting base 31 and is rotatably connected to the connecting base 31, and a spring 33 is connected between the connecting base 31 and the mounting base 32. When the fixed water pipe 11 and the movable water pipe 12 hit an obstacle, the mounting base 32 is rotatably connected to the connecting base 31, so that the dustproof structure 1 can rotate backward to avoid the obstacle. When the dustproof structure 1 rotates backward, the spring 33 is stretched. After avoiding the obstacle, the spring 33 can automatically shrink and reset, so that the dustproof structure 1 returns to its original position under the action of the spring 33, thereby playing an anti-collision and reset role.

[0034] One end of the fixed water pipe 11 and the movable water pipe 12 are both mounted on the mounting structure 3. Specifically, Figure 2 , Figure 3 As shown, in some embodiments, two slots 321 are provided on the inner side of the mounting base 32, and one end of the fixed water pipe 11 and the movable water pipe 12 are respectively fitted and inserted in the two slots 321, and the movable water pipe 12 can rotate in the slots 321; a fixing clamp 322 is also provided on the mounting base 32 at a position corresponding to the fixed water pipe 11, and the fixing clamp 322 is sleeved on the fixed water pipe 11, and its two ends are connected to the mounting base 32 by bolts to fix the fixed water pipe 11.

[0035] In order to realize the switching of the dustproof structure 1 between the working state and the storage state, in some embodiments, the storage adjustment structure 4 includes a cylinder 41 and a mounting seat 42, the mounting seat 42 is fixedly connected to the mounting plate 8, one end of the cylinder 41 is rotatably installed on the mounting seat 42 through a rotating shaft, and the telescopic end of the cylinder 41 is rotatably connected to the connecting base 31. When the movable rod of the cylinder 41 contracts, it can drive the connecting base 31 of the dustproof structure 1 to rotate along the end connected to the mounting plate 8 to the outside of the frame 7, so that the dustproof structure 1 is in a working state to facilitate watering; when the piston rod of the cylinder 41 is extended, it can drive the dustproof structure 1 to rotate along the end connected to the mounting plate 8 toward the inside of the frame 7, thereby rotating to the storage state, thereby realizing the folding and storage of the dustproof structure 1.

[0036] like Figure 5As shown, in some embodiments, the driving structure 2 includes a motor 21 and a transmission structure 22, and the driving shaft of the motor 21 is connected to the movable water pipe 12 through the transmission structure 22, and the movable water pipe 12 can be driven to reciprocate and rotate at a set angle through the transmission structure 22. Specifically, the motor 21 is a swing motor 21, and when the water mist nozzle of the movable water pipe 12 is driven by the motor 21 to rotate downward, the water mist nozzle will not collide with the fixed water pipe 11.

[0037] It can be understood that the motor 21 is mounted on the mounting base plate, and the transmission structure 22 can be a pulley transmission component or a gear transmission component. When the transmission structure 22 is a pulley transmission component, it includes two pulleys and a belt. The two pulleys are respectively connected to the drive shaft of the motor 21 and the active water pipe 12, and the belt is sleeved between the two pulleys. When the transmission structure 22 is a gear transmission component, it includes two gears, the two gears are respectively connected to the drive shaft of the motor 21 and the active water pipe 12, and the two gears are meshed and rotatably connected, so that the motor 21 can drive the active water pipe 12 to reciprocate and rotate at a set angle under the transmission of the transmission structure 22.

[0038] In some embodiments, the fixed water pipe 11 is fixedly connected to the water inlet pipe 9. Figure 6 As shown, one end of the movable water pipe 12 is arranged inside the water inlet pipe 9, and is rotatably connected and communicated with the water inlet pipe 9, and the lengths of the fixed water pipe 11 and the movable water pipe 12 are equal. It can be understood that water valves can be separately arranged at the water inlet ends of the fixed water pipe 11 and the movable water pipe 12 to separately control the opening and closing of the fixed water pipe 11 and the movable water pipe 12, so as to flexibly use the dust prevention system.

[0039] Working principle: During operation, the dustproof structure 1 is driven to rotate to the outside of the frame 7 by the contraction of the cylinder 41, so that the dustproof structure 1 is in working state. At this time, the fixed water pipe 11 and the movable water pipe 12 are both perpendicular to the frame 7, and the fixed water pipe 11 and the movable water pipe 12 are arranged horizontally on the side of the cleaning brush 5 away from the cab. Then the water valve of the water inlet pipe 9 is opened, and the fixed water pipe 11 sprays water to the cleaning end of the cleaning brush 5 through the sprinkler nozzle during the cleaning process. At the same time, the motor 21 is turned on to drive the movable water pipe 12 to swing back and forth, so that the movable water pipe 12 rotates through the water mist nozzle to spray water mist to prevent the dust raised during the cleaning process from spreading; after the cleaning work is completed, the cylinder 41 is started to extend its movable rod, driving the dustproof structure 1 to rotate to the storage state, so that the dustproof structure 1 of the dustproof system can be folded and stored.

[0040] The utility model has a dustproof structure 1 and a driving structure 2. The dustproof structure 1 is arranged on the side of the cleaning brush 5 of the sweeper away from the cab. The sprinkler head of the fixed water pipe 11 corresponds to the cleaning end of the cleaning brush 5, and can sprinkle water to the cleaning end of the cleaning brush 5 during the cleaning process to reduce the dust raised during the cleaning process; the movable water pipe 12 is arranged above the fixed water pipe 11, and can reciprocate under the drive of the driving structure 2, driving the water mist nozzle to rotate to spray water mist, so that a large range of water mist can be sprayed behind the cleaning brush 5 during the driving process of the sweeper to prevent the dust raised during the cleaning process from spreading, and the dustproof effect of the sweeper is good.
