Description
Technical Field
[0001] This invention belongs to the field of curbstone cleaning technology, and specifically relates to a curbstone cleaning device. Background Technology
[0002] Curbstones are marker stones placed between the road surface and other structures. They are generally required between the median strip and the road surface, and between the sidewalk and the road surface in urban roads. They are also commonly found at the edges of the central median strip, the right edge of the driving lane, or the outer edge of the shoulder. To beautify the city and meet environmental protection requirements, curbstones need to be cleaned regularly to remove surface stains. This cleaning is usually done using a cleaning truck. The truck is equipped with a special device for cleaning curbstones. During cleaning, two roller brushes on the cleaning device are activated, which clean the top of the curbstone and one side of the road. Simultaneously, water is sprayed to rinse away dirt. Currently, the distance between the two roller brushes on the curb cleaning device is fixed. However, there are many curbs, and the size and exposed area of the curbs are not fixed. As a result, when cleaning some curbs, the cleaning is incomplete, and some stains remain on the surface of the curb. Therefore, in order to solve this problem, this application provides a curb cleaning device to meet the needs. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a curbstone cleaning device.
[0004] To achieve the above objectives, the present invention provides a curbstone cleaning device, including a sweeper vehicle. One end of the sweeper vehicle is equipped with a control arm, and one end of the control arm is fixedly connected to a connecting frame and an adjustment assembly. The adjustment assembly is used to adjust the curbstone cleaning process accordingly. The adjustment assembly is connected to the connecting frame. The adjustment assembly includes a fixed frame fixedly connected to the bottom of the connecting frame. A limiting groove frame is fixedly connected to one side of the fixed frame. A first blocking member is slidably connected to the bottom of the limiting groove frame. A connecting limiting block is fixedly connected to the top of the first blocking member. The connecting limiting block is slidably connected to the inner side of the limiting groove frame. A positioning rod is fixedly connected to the inner side of the limiting groove frame. The connecting limiting block is slidably sleeved on the outer side of the positioning rod. A sliding groove frame is fixedly connected to one side of the limiting groove frame, and the sliding groove frame is slidably connected to the top of the first blocking member.
[0005] In the above technical solution, the number of limiting slots is set to two, and the two limiting slots are distributed on both sides of the slide frame. One end of the slide frame is open. An adjusting slider is fixedly connected to the top of the first blocking member, and the adjusting slider is slidably connected to the inner side of the slide frame.
[0006] In the above technical solution, a first spring is fixedly connected to one side of the adjusting slider, the first spring is fixedly connected to the inner side of the slide frame, a damper is provided between the adjusting slider and the slide frame, a drive motor is fixedly connected to the top of the first shield, a cleaning component is rotatably connected inside the first shield, and the cleaning component is connected to the output end of the drive motor.
[0007] In the above technical solution, a support rod is further provided on one side of the fixed frame, one end of the support rod is rotatably connected to a universal pulley, a rectangular sleeve is fixedly connected to the bottom of the support rod, and an auxiliary slide rod is slidably connected to the inner side of the rectangular sleeve.
[0008] In the above technical solution, one end of the auxiliary slide rod is fixedly connected to a first auxiliary stop, the inner side of the first auxiliary stop is rotatably connected to a second limiting wheel, the top of the first auxiliary stop is fixedly connected to a fixed connecting plate, and the fixed connecting plate is fixedly connected to one side of the connecting limiting block.
[0009] In the above technical solution, a side connecting rod is further fixedly installed on the top of the fixing frame, a limit post is fixedly connected to the top of the side connecting rod, and a top plate is fixedly connected to the top of the limit post.
[0010] In the above technical solution, further, a limiting slider is slidably connected to the outer side of the limiting post, and a second spring is fixedly connected to the top of the limiting slider, and the second spring is fixedly connected to the bottom of the top plate.
[0011] In the above technical solution, a second blocking member is fixedly connected to one side of the limiting slider, a fixed bracket is fixedly connected to one side of the second blocking member, a second auxiliary stop member is fixedly connected to the bottom of the fixed bracket, and a first limiting wheel is rotatably connected to the inner side of the second auxiliary stop member.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting an adjustment component, enables the two cleaning components to, when encountering a large difference in the size and exposed area of a curbstone, to respectively keep the first blocking component stationary while adjusting the position of the second blocking component, so that the cleaning component inside the second blocking component can fully contact the top of the curbstone for complete cleaning of the top of the curbstone, and to keep the second blocking component stationary while adjusting the position of the first blocking component, so that the first blocking component can be lowered to the center of the side of the curbstone, thereby ensuring complete contact with the side of the curbstone when a large portion of the curbstone is exposed. This allows for comprehensive cleaning of curbstones of different types and configurations.
[0013] 2. By setting up a first shielding member and a second shielding member, the splashing water generated by the sweeping member brushing the curbstone will be blocked inside the first shielding member and the second shielding member respectively under the protection of the first shielding member and the second shielding member. This can prevent water splashing from coming into contact with pedestrians and from staining greenery and reducing the aesthetics of the city. In order to ensure that the sweeping member can fully contact the curbstone, the first shielding member and the second shielding member cannot completely cover the sweeping member inside. This will cause some water to escape from the gap between the second limiting wheel and the sweeping member. At this time, the first and second auxiliary shielding members can block this part of the water, thereby completely blocking the splashing water. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] like Figures 1-3The illustrated curbstone cleaning device includes a sweeper 1, a control arm 2 at one end of the sweeper 1, a connecting frame 3 fixedly connected to one end of the control arm 2, and an adjustment assembly. The adjustment assembly is used to adjust the sweeping of the curbstone accordingly. The adjustment assembly is connected to the connecting frame 3 and includes a fixing frame 4 fixedly connected to the bottom of the connecting frame 3. A limiting groove frame 5 is fixedly connected to one side of the fixing frame 4. A first blocking member 6 is slidably connected to the bottom of the limiting groove frame 5. The overall outline of the first blocking member 6 is adapted to the overall outline of the sweeping member 30. One side of the first blocking member 6 is open, allowing the sweeping member 30 to extend through the opening from the inside of the first blocking member 6 and contact the curbstone. A connecting limiting block 7 is fixedly connected to the top of the first blocking member 6 and slidably connected to the inside of the limiting groove frame 5. A positioning device is fixedly connected to the inside of the limiting groove frame 5. The positioning rod 8 is slidably sleeved on the outside of the positioning rod 8 by connecting and limiting blocks 7 on both sides. The first blocking member 6 is connected to the limiting slot frame 5 through the connecting and limiting blocks 7 on both sides, and can slide to a certain extent while being limited by the limiting slot frame 5. A sliding frame 10 is fixedly connected to one side of the limiting slot frame 5. The sliding frame 10 is slidably connected to the top of the first blocking member 6. The number of limiting slot frames 5 is set to two. The two limiting slot frames 5 are distributed on both sides of the sliding frame 10 and are connected to the sliding frame 10. One end of the sliding frame 10 is open. An adjusting slider 11 is fixedly connected to the top of the first blocking member 6. The adjusting slider 11 is slidably connected to the inside of the sliding frame 10. A first spring 12 is fixedly connected to one side of the adjusting slider 11. The first spring 12 is fixedly connected to the inside of the sliding frame 10. The first blocking member 6 can be kept in its initial state by the stretching of the first spring 12. Figure 3 The state is such that a damper is provided between the adjusting slider 11 and the slide frame 10. The top of the first shield 6 is fixedly connected to the drive motor 13. The cleaning component 30 is rotatably connected inside the first shield 6. The cleaning component 30 is connected to the output end of the drive motor 13. The cleaning component 30 is a roller brush used for cleaning curbs in the prior art.
[0018] A support rod 14 is provided on one side of the fixed frame 4. One end of the support rod 14 is rotatably connected to a universal pulley 15. The universal pulley 15 can rotate freely to improve the flexibility of the sweeping device when moving. A rectangular sleeve 16 is fixedly connected to the bottom of the support rod 14. An auxiliary slide rod 17 is slidably connected to the inner side of the rectangular sleeve 16. One end of the auxiliary slide rod 17 is fixedly connected to a first auxiliary stop 18. A water spray gun is provided on one side of the first auxiliary stop 18. The water spray gun is connected to the water pump on the sweeper 1 through a water pipe. The inner side of the auxiliary stop 18 is rotatably connected to a second limiting wheel 29. The first auxiliary stop 18 has an arc-shaped profile. The second limiting wheel 29 extends from the inner side of the first auxiliary stop 18. The top of the first auxiliary stop 18 is fixedly connected to a fixed connecting plate 19. The fixed connecting plate 19 is fixedly connected to one side of the connecting limiting block 7. The first auxiliary stop 18 is connected to the connecting limiting block 7 through the fixed connecting plate 19 and then to the first blocking member 6. The stability of the first auxiliary stop 18 can be improved by the rectangular sleeve 16 and the auxiliary slide rod 17.
[0019] It should be noted that, during the cleaning of the curb, the adjustment assembly is extended to one side of the curb by controlling the control arm 2, so that the first shield 6 is located on the road side of the curb, and the second shield 25 is located on top of the curb. After the control arm 2 makes the universal pulley 15 contact the ground and the second limit wheel 29 contact the side of the curb, the drive motor 13 on the first shield 6 and the second shield 25 can be activated, causing the two cleaning parts 30 to rotate and the two water spray guns to spray water to wash the curb, thus coordinating the two cleaning parts 30 to clean the curb. The first shield 6 and the second shield 25 provide protection against water damage. Under the protection of the first shield 6 and the second shield 25, the splashing water generated by the sweeping component 30 when washing the curb will be blocked inside the first shield 6 and the second shield 25 respectively. This can prevent water from splashing and coming into contact with pedestrians and from staining the greenery and reducing the aesthetics of the city. In order to ensure that the sweeping component 30 can fully contact the curb, the first shield 6 and the second shield 25 cannot completely cover the sweeping component 30 inside. This will cause some water to escape from the gap between the second limit wheel 29 and the sweeping component 30. At this time, the first auxiliary baffle 18 and the second auxiliary baffle 27 can block this part of the water, thus completely blocking the splashing water.
[0020] like Figures 2-5As shown, a side connecting rod 20 is fixedly installed on the top of the fixed frame 4. A limiting post 21 is fixedly connected to the top of the side connecting rod 20. A top plate 24 is fixedly connected to the top of the limiting post 21. A limiting slider 22 is slidably connected to the outer side of the limiting post 21. A second spring 23 is fixedly connected to the top of the limiting slider 22. The second spring 23 is fixedly connected to the bottom of the top plate 24. A second blocking member 25 is fixedly connected to one side of the limiting slider 22. A water spray gun is provided on one side of the second blocking member 25. The second blocking member 25 is the same as the first blocking member 6 and is also provided with a drive motor 13 and a cleaning member 30. A fixed bracket 26 is fixedly connected to one side of the second blocking member 25. A second auxiliary stop 27 is fixedly connected to the bottom of the fixed bracket 26. A first limiting wheel 28 is rotatably connected to the inner side of the second auxiliary stop 27. The second auxiliary stop 27 and the first limiting wheel 28 are the same as the first auxiliary stop 18 and the second limiting wheel 29.
[0021] It should be noted that, in cases where the size or exposed area of the curbstone does not match the size of the two sweeping components 30, causing the sweeping component 30 inside the second blocking component 25 to not fully contact the top of the curbstone, the movement of the adjustment component can be controlled by the control arm 2 to make the second limiting wheel 29 contact the side of the curbstone. At this time, the first blocking component 6 remains stationary due to the contact between the second limiting wheel 29 and the curbstone, while the fixing frame 4 drives the second blocking component 25 to continuously move towards the top of the curbstone until the sweeping component inside the second blocking component 25... 30 is in complete contact with the top of the curbstone. During this period, since the first blocking member 6 and the first auxiliary blocking member 18 remain stationary, the rectangular sleeve 16 slides on the outside of the auxiliary slide rod 17. At the same time, the connecting limiting block 7 slides on the outside of the limiting groove frame 5 and the positioning rod 8. This allows the first blocking member 6 to remain stationary when the fixing frame 4 moves. Meanwhile, the adjusting slider 11 compresses the first spring 12 and the damper to make them contract and slide on the inside of the slide frame 10. This allows the first blocking member 6 to remain stationary and to support the second... The blocking member 25 is adjusted to its corresponding position to fully contact the top of the curbstone and complete the cleaning of the top of the curbstone. Simultaneously, when the curbstone is exposed at a relatively high position, the control arm 2 can be used to continuously lower the fixing frame 4 until the cleaning member 30 is located at the center of the side of the curbstone. During this period, the first limiting wheel 28 contacts the top of the curbstone, preventing the second blocking member 25 from descending further. Since the second blocking member 25 can slide outside the limiting post 21 via the limiting slider 22, after the first limiting wheel 28 contacts the top of the curbstone... As the fixed frame 4 continues to descend, it causes the side connecting rod 20 and the top plate 24 to slide downward inside the limiting slider 22. The top plate 24 compresses the second spring 23, thereby keeping the second blocking member 25 stationary while the fixed frame 4 descends. This adjusts the position of the first blocking member 6, allowing the side of the curbstone to be completely cleaned. In this way, when there is a large difference between the size of the curbstone and the exposed area, the size between the two roller brushes can be adjusted by adjusting the component, so that the curbstone with different settings can be cleaned accordingly.
[0022] Working principle: By controlling the movement of the adjustment component through the control arm 2, the second limiting wheel 29 contacts the side of the curb. At this time, the first blocking member 6 remains stationary due to the contact between the second limiting wheel 29 and the curb. Simultaneously, the fixing frame 4 drives the second blocking member 25 to continuously move towards the top of the curb until the cleaning member 30 inside the second blocking member 25 is in complete contact with the top of the curb. During this period, since the first blocking member 6 and the first auxiliary stop 18 remain stationary, the rectangular sleeve 16 slides on the outside of the auxiliary slide rod 17. At the same time, the connecting limiting block 7 is in the limiting groove frame 5 and... The positioning rod 8 slides on the outside, thus keeping the first blocking member 6 stationary when the fixing frame 4 moves. Simultaneously, the adjusting slider 11 compresses the first spring 12 and damper, causing them to contract and slide on the inside of the slide rail frame 10. This keeps the first blocking member 6 stationary while adjusting the position of the second blocking member 25 accordingly, ensuring complete contact with the top of the curbstone for thorough cleaning. When the second limiting wheel 29 separates from the curbstone, the first spring 12 stretches, causing the first blocking member 6 to reset, and simultaneously the damper... The device slows down the displacement speed of the first blocking member 6 and prevents it from shaking. When the curbstone is exposed high, the control arm 2 can be used to continuously lower the fixing frame 4 until the sweeping member 30 is located at the center of the side of the curbstone. During this period, the first limiting wheel 28 contacts the top of the curbstone, preventing the second blocking member 25 from continuing to descend. Since the second blocking member 25 can slide on the outside of the limiting post 21 via the limiting slider 22, after the first limiting wheel 28 contacts the top of the curbstone, the continuous descent of the fixing frame 4 will drive the side connecting rod 20 and the top plate 24 to the limiting slider. The inner side of 22 slides downward, and the top plate 24 compresses the second spring 23, so that when the fixed frame 4 descends, the second blocking member 25 remains stationary and the position of the first blocking member 6 is adjusted so that the side of the curbstone can be completely cleaned. When the first limiting wheel 28 separates from the curbstone, the second spring 23 stretches to drive the second blocking member 25 to reset. In this way, when there is a large difference between the size of the curbstone and the exposed area, the size between the two roller brushes can be adjusted by adjusting the component, so as to perform corresponding comprehensive cleaning for curbstones with different settings.
