Description

Technical Field

[0001] This utility model relates to the field of road roller cleaning, and in particular to a scraper cleaning device for road rollers. Background Technology

[0002] The scraper blades of a road roller, also known as mud scrapers, regularly remove impurities from the roller's steel wheels, preventing these impurities from accumulating around or inside the roller. This keeps the roller clean, which not only improves the appearance of the construction work but also reduces equipment malfunctions and damage caused by impurity buildup, thus ensuring the cleanliness of the roller's steel wheels and the efficient operation of compaction.

[0003] In existing technology, when the roller rotates, its outer wall passes through a scraper, which removes impurities, thus cleaning the impurities outside the roller. However, there are certain limitations in actual use. As the impurities scraped off by the scraper fall onto the road surface under the action of gravity, they either fall around the roller or re-adhere to the steel wheel, forming accumulations that affect the normal operation of the roller. Furthermore, the accumulation of impurities on the roller's steel wheel can lead to uneven compaction, affecting the quality of the road. Moreover, when not in use, the structural components occupy space, resulting in poor operational flexibility. Therefore, a scraper cleaning device for a roller is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where impurities scraped off by the scraper fall onto the road surface under gravity, landing around the roller or re-adhering to the steel wheel, forming accumulations that affect the normal operation of the roller. Furthermore, the accumulation of impurities on the roller's steel wheel leads to uneven compaction, affecting the quality of the road. Additionally, when not in use, the structural components occupy space, resulting in poor operational flexibility. Therefore, this invention proposes a scraper cleaning device for rollers to solve the aforementioned problems.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A scraper cleaning device for a road roller, comprising:

[0007] The roller body and scraper body are provided. A pressure roller is rotatably mounted on the bottom of the roller body. A bracket is fixedly mounted on the outer wall of the roller body, and the scraper body is mounted on the bracket. A collection assembly is mounted on the bracket, and the collection assembly includes:

[0008] The connecting frame and the collection box are provided. The outer wall of the connecting frame is rotatably connected to the outer wall of the support through a pin. The outer wall of the connecting frame is provided with an installation groove. A connecting block is fixedly provided on the top of the collection box and is engaged and snapped into the installation groove.

[0009] A limiting unit, which is mounted on the connecting frame, is used to restrict the connecting block within the mounting slot.

[0010] Preferably, the limiting unit includes a crossbar and a closing plate. The crossbar is fixedly connected between two sets of connecting frames. A connecting groove is provided inside the crossbar. One end of the closing plate extends through the connecting groove into the mounting groove.

[0011] Preferably, a compression spring is fixedly installed inside the connecting groove, and the other end of the compression spring is fixedly installed on the outer wall of the closed plate.

[0012] Preferably, the outer wall of the crossbar has a movable opening, the inner wall of the movable opening is movably engaged with a movable block, and the outer wall of the movable block is fixedly connected to the outer wall of the closed plate.

[0013] Preferably, an adjustment plate is fixedly connected to the outer wall of the moving block, and the adjustment plate covers the outer wall of the moving port.

[0014] Preferably, a fixing block is fixedly provided on the outer wall of the crossbar, a groove is provided inside the fixing block, and a circular plate is movably inserted into the inner wall of the groove provided inside the fixing block.

[0016] Preferably, a support block is fixedly provided at the bottom of the bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by setting the connection relationship between the roller body, scraper body, connecting frame, collection box, and crossbar, the connecting block is aligned and inserted into the mounting groove. Then, the closing plate is pushed by the compression spring, causing the closing plate to be inserted into the mounting groove and sealing the mounting groove. This facilitates the confinement of the connecting block within the mounting groove, preventing it from detaching from the groove. It also facilitates the installation and confinement of the collection box on the connecting frame. When the roller rotates clockwise, the scraper body scrapes away impurities from the outer wall of the roller. Since the scraper body is inclined, the impurities are carried away by gravity along the outer wall of the scraper body. The wall slides downwards into the collection box, facilitating timely removal and collection of impurities, improving cleaning efficiency, and reducing the amount of impurities falling onto the road surface and affecting its smoothness. The connection between the crossbar, fixing block, connecting rod, hanging ring, and fixing hook allows the connecting frame to remain vertical when not in use. This is achieved by flipping the connecting frame upwards, pulling the hanging ring upwards, and attaching it to the fixing hook. This facilitates folding the connecting frame, avoiding unnecessary space occupation, and effectively preventing unnecessary damage to the support structure, thus extending the equipment's lifespan.

[0019] 2. In this utility model, a spring bar is provided inside the fixing block, so that the pushing force of the spring bar pushes the circular plate into the inner cavity of the fixing block, thereby driving the connecting rod to move and pulling the hanging ring, thus restricting the hanging ring on the fixing hook and improving stability.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example: This example provides a scraper cleaning device for a road roller. See [link to example]. Figure 1-5 Specifically, including:

[0030] The roller body 1 and the scraper body 102 are provided. A pressure roller is rotatably mounted on the bottom of the roller body 1. A bracket 101 is fixedly mounted on the outer wall of the roller body 1, and the scraper body 102 is mounted on the bracket 101. One end of the scraper body 102 is attached to the outer wall of the pressure roller. When the pressure roller rotates clockwise, impurities on its outer wall are scraped off by the scraper body 102. By setting the scraper body 102 to an inclined shape, impurities slide downward along the outer wall of the scraper body 102 under the action of gravity. A collection assembly is provided on the bracket 101, which includes:

[0031] The connecting frame 2 and the collection box 3 are connected to the outer wall of the bracket 101 by a pin. The outer wall of the connecting frame 2 is provided with an installation groove 201. The top of the collection box 3 is fixedly provided with a connecting block 301, which is engaged and locked in the installation groove 201. Impurities slide down the outer wall of the scraper body 102 under the action of gravity and fall into the collection box 3, which is convenient for collection and reduces the impact on the road surface and the smoothness of the road surface. By pulling the collection box 3 forward, the connecting block 301 is moved forward and disengaged from the installation groove 201, which makes it easy to remove the collection box 3 from the roller body 1 for cleaning.

[0032] A limiting unit is provided on the connecting frame 2. The limiting unit is used to restrict the connecting block 301 within the mounting groove 201.

[0033] The limiting unit includes a crossbar 4 and a closing plate 403. The crossbar 4 is fixedly connected between two sets of connecting frames 2. A connecting groove 401 is opened inside the crossbar 4. One end of the closing plate 403 extends into the mounting groove 201 through the connecting groove 401. In use, when the connecting block 301 is inserted into the mounting groove 201, it moves into the mounting groove 201 through the closing plate 403, thereby closing the mounting groove 201. This helps to restrict the connecting block 301 within the mounting groove 201, preventing the connecting block 301 from detaching from the mounting groove 201 at will, and promoting the stability of the collection box 3 installation.

[0034] A compression spring 402 is fixedly installed in the inner cavity of the connecting groove 401. The other end of the compression spring 402 is fixedly installed on the outer wall of the sealing plate 403. The sealing plate 403 is pushed by the pushing force of the compression spring 402, so that the sealing plate 403 moves into the inner cavity of the mounting groove 201, which facilitates the sealing of the mounting groove 201.

[0035] The outer wall of the crossbar 4 has a movable opening 404, and the inner wall of the movable opening 404 is movably engaged with a movable block 405. The outer wall of the movable block 405 is fixedly connected to the outer wall of the closed plate 403, which is used to extend the action point of the closed plate 403, so that the user can move the closed plate 403 by moving the movable block 405.

[0036] An adjustment plate 406 is fixedly connected to the outer wall of the movable block 405, and the adjustment plate 406 covers the outer wall of the movable port 404, which facilitates the shielding of the movable port 404 and reduces the entry of dust and impurities into the connecting groove 401 through the movable port 404.

[0037] A fixing block 5 is fixedly installed on the outer wall of the crossbar 4. The fixing block 5 has a groove inside, and a circular plate 502 is movably inserted into the inner wall of the groove. A connecting rod 501 is fixedly installed on the top of the circular plate 502. A hanging ring 504 is rotatably connected to the outer wall of the connecting rod 501 through a pin. A fixing hook 505 is fixedly installed on the outer wall of the roller body 1, and the hanging ring 504 is hung on the fixing hook 505. When the collection box 3 is not needed, the connecting frame 2 is flipped upward to make the connecting frame 2 vertical. The upward rotation of the connecting frame 2 drives the crossbar 4 to move upward, which in turn drives the fixing block 5 and the hanging ring 504 to move upward. The user can pull the hanging ring 504 upward and hang it on the fixing hook 505 to keep the connecting frame 2 vertical. This makes it easy to fold the connecting frame 2, avoid taking up unnecessary space, and also effectively prevent the bracket 101 from being damaged, thus extending the service life of the equipment.

[0038] A spring strip 503 is fixedly installed on the inner wall of the groove opened inside the fixing block 5, and the other end of the spring strip 503 is fixedly installed on the outer wall of the circular plate 502. The circular plate 502 is pushed into the inner cavity of the fixing block 5 by the pushing force of the spring strip 503, which drives the connecting rod 501 to move, thereby pulling the hanging ring 504 and restricting the hanging ring 504 on the fixing hook 505 to improve stability.

[0039] A support block 103 is fixedly installed at the bottom of the bracket 101, which restricts the use range of the connecting frame 2 and provides support for the bottom of the connecting frame 2.

[0040] Specifically, the working principle and operation method of this utility model are as follows:

[0041] In use, by pushing the adjusting plate 406 towards the center point of the crossbar 4, the moving adjusting plate 406 causes the moving block 405 to move, which in turn causes the closing plate 403 to move, causing the closing plate 403 to retract into the connecting groove 401. At this time, the closing plate 403 moves out of the mounting groove 201, which is now in the open state. By aligning and inserting the connecting block 301 into the mounting groove 201, and then releasing the pushing adjusting plate 406, the pushing force of the compression spring 402 pushes the closing plate 403, causing the closing plate 403 to insert into the mounting groove 201. The groove 201 is closed, which makes it easy to confine the connecting block 301 within the groove 201 and prevents the connecting block 301 from detaching from the groove 201 at will. It also makes it easy to install and confine the collection box 3 on the connecting frame 2. When the pressure roller rotates clockwise, its scraper body 102 scrapes the impurities on the outer wall of the pressure roller. By setting the scraper body 102 to be inclined, the impurities slide down the outer wall of the scraper body 102 under the action of gravity and fall into the collection box 3, which makes it easy to collect them and reduces the amount of impurities falling onto the road surface and affecting the smoothness of the road surface.

[0042] When the collection box 3 is no longer needed, it can be removed from the connecting frame 2. The user can then rotate the connecting frame 2 upwards to make it vertical. This upward rotation of the connecting frame 2 will cause the crossbar 4 to move upwards, which in turn will move the fixing block 5 and the hanging ring 504 upwards. The user can then pull the hanging ring 504 upwards and hook it onto the fixing hook 505. By releasing the hanging ring 504, the spring bar 503 will push the circular plate 502 into the cavity of the fixing block 5, causing the connecting rod 501 to move. This will pull the hanging ring 504, securing it to the fixing hook 505, improving stability, keeping the connecting frame 2 vertical, facilitating its folding, avoiding unnecessary space occupation, and effectively preventing unnecessary damage to the support, thus extending the service life of the equipment.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
