Description

Technical Field

[0001] This utility model relates to the field of road roller sludge scraping technology, and in particular to a road roller sludge scraping device for municipal engineering. Background Technology

[0002] In municipal engineering construction, road rollers are an indispensable and important piece of machinery, widely used in the compaction of infrastructure such as roads and squares. During the compaction process, impurities such as mud, sand, gravel, and asphalt residue on the road surface are easily adhered to the surface of the road roller's roller.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing scraping devices lack a structure to guide and process the scraped-off mud, gravel, asphalt, and other residues. This results in the residues potentially being picked up again by the roller and re-adheded to the roller surface, thus affecting the smoothness and compaction quality of the road surface.

[0004] Therefore, a mud scraping device for road rollers used in municipal engineering is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a mud scraping device for road rollers used in municipal engineering, which can solve the problem that the existing mud scraping devices for road rollers lack a structure to guide and process the scraped mud, gravel, asphalt and other residues, which may cause the residues to be picked up again by the roller and re-adhere to the roller surface, thus affecting the smoothness and compaction quality of the road surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mud scraping device for a road roller used in municipal engineering, comprising two connecting frames, a mud scraping mechanism being bolted to the inner side of the bottom of the connecting frames, and a mud guiding mechanism being fixedly connected to the bottom of the mud scraping mechanism;

[0007] The mud guiding mechanism includes a mud storage box, an auger, a friction wheel, a mud discharge hole, and a support plate. The mud storage box is fixedly connected to the bottom of the mud scraping mechanism. The auger is rotatably connected to the inner side of the mud storage box. The left side of the auger extends through and to the outer side of the mud storage box. The friction wheel is fixedly connected to the left side of the auger. The mud discharge hole is opened on the right side of the mud storage box. The support plate is welded to the inner side of the mud discharge hole. The right side of the auger is rotatably connected to the surface of the support plate.

[0008] Preferably, the sludge scraping mechanism includes a limiting plate, a scraper, a baffle, a guide port, and a guide cover, wherein the limiting plate is fixedly connected to the inner side of the bottom of the connecting frame.

[0009] Preferably, the scraper is welded to the bottom of the limiting plate, and the cover is fixedly connected to the top of the scraper.

[0010] Preferably, the guide opening is located on the rear side of the limiting plate, and the guide cover is fixedly connected to the rear side of the limiting plate.

[0011] Preferably, a limiting ring is fixedly connected to the left side of the auger, and the surface of the limiting ring is coated with an anti-corrosion coating.

[0012] Preferably, the top of the connecting frame has connecting holes on both sides, and the surface of the connecting frame is coated with an anti-corrosion coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this application, the limiting plate in the sludge scraping mechanism is fixedly connected to the inner side of the bottom of the connecting frame, and the scraper is welded to the bottom of the limiting plate. This connection method makes the overall structure of the sludge scraping mechanism stable and can be firmly installed on the road roller, ensuring that it will not easily shake or fall off during operation, thereby ensuring the stability and reliability of the sludge scraping work. The guide port is opened on the rear side of the limiting plate, and the guide cover is fixedly connected to the rear side of the limiting plate.

[0017] 2. The mud guiding mechanism of this application utilizes the contact between the friction wheel and the roller drum, relying on friction to drive the auger to rotate, thereby realizing the automatic transfer of residue in the mud storage box. This design does not require an additional power source, saving energy, and can be synchronized with the operation of the roller, improving work efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A mud scraping device for a road roller used in municipal engineering includes two connecting frames 1. A mud scraping mechanism 2 is bolted to the inner side of the bottom of the connecting frame 1, and a mud guiding mechanism 3 is fixedly connected to the bottom of the mud scraping mechanism 2.

[0027] The mud guiding mechanism 3 includes a mud storage box 31, an auger 32, a friction wheel 33, a mud discharge hole 34, and a support plate 35. The mud storage box 31 is fixedly connected to the bottom of the mud scraping mechanism 2. The auger 32 is rotatably connected to the inside of the mud storage box 31. The left side of the auger 32 extends through and to the outside of the mud storage box 31. The friction wheel 33 is fixedly connected to the left side of the auger 32. The mud discharge hole 34 is opened on the right side of the mud storage box 31. The support plate 35 is welded to the inside of the mud discharge hole 34. The right side of the auger 32 is rotatably connected to the surface of the support plate 35.

[0028] In this embodiment: By setting a connecting frame 1 to connect with the road roller, a stable installation position is provided for the sludge scraping mechanism 2 and the sludge guiding mechanism 3, ensuring that the sludge scraping device can be firmly installed on the road roller. The sludge storage box 31 provides a relatively enclosed space to collect the scraped residue, preventing the residue from being scattered randomly at the construction site, which is conducive to maintaining the cleanliness of the construction environment. At the same time, it is convenient to centrally process the residue. The auger 32 uses the rotation of the spiral blades to transport the residue in the sludge storage box 31 from one end to the other, realizing the orderly transmission of the residue and avoiding the accumulation of residue in the sludge storage box 31. This ensures the continuous and effective operation of the sludge guiding mechanism 3. The friction wheel 33 drives the auger 32 to rotate by contact with the roller of the road roller using friction, without the need for an additional power source. The sludge discharge hole 34 can discharge the residue in the sludge storage box 31, maintain the space in the sludge storage box 31, and ensure the normal operation of the sludge guiding mechanism 3. The support plate 35 provides support for the right side of the auger 32.

[0029] Specifically, such as Figure 3 As shown, the sludge scraping mechanism 2 includes a limiting plate 21, a scraper 22, a baffle 23, a guide port 24, and a guide cover 25. The limiting plate 21 is fixedly connected to the inner side of the bottom of the connecting frame 1.

[0030] Specifically, such as Figure 3 As shown, the scraper 22 is welded to the bottom of the limiting plate 21, and the cover 23 is fixedly connected to the top of the scraper 22.

[0031] Specifically, such as Figure 3 As shown, the guide port 24 is opened on the rear side of the limiting plate 21, and the guide cover 25 is fixedly connected to the rear side of the limiting plate 21.

[0032] In this embodiment: the limiting plate 21 provides stable support for the scraper 22. The scraper 22 directly contacts the surface of the roller drum and scrapes away the mud, sand, asphalt and other residues adhering to the surface of the roller drum through its sharp edge, ensuring the cleanliness of the roller drum. The cover 23 is installed on the top of the scraper 22 to prevent residue from splashing during the scraping process. The guide port 24 provides a channel for the scraped residue to enter the mud guiding mechanism 3, so that the residue can smoothly enter the mud storage box 31 from the mud scraping mechanism 2. The guide cover 25 cooperates with the guide port 24 to guide the residue into the guide port 24.

[0033] Specifically, such as Figure 4 As shown, a limiting ring 4 is fixedly connected to the left side of the auger 32, and the surface of the limiting ring 4 is coated with an anti-corrosion coating.

[0034] Specifically, such as Figure 2 As shown, the top of the connecting frame 1 has connecting holes 5 on both sides, and the surface of the connecting frame 1 is coated with anti-corrosion paint.

[0035] In this embodiment: by setting a limiting ring 4, the friction wheel 33 is limited; by setting an anti-corrosion coating, the limiting ring 4 can be prevented from rusting and corroding when in contact with mud, water and other substances, thus extending its service life; by setting a connecting hole 5, the connection between the sludge scraper and the road roller is facilitated; the sludge scraper can be firmly installed on the road roller using bolts and other connecting parts through the connecting hole 5; by setting an anti-corrosion coating, the connecting frame 1 can be prevented from rusting and corroding, thus extending its service life.

[0036] Specifically, such as Figure 4 As shown, the surface of the friction wheel 33 is engraved with anti-slip texture, and the depth of the anti-slip texture is 2-3mm.

[0037] Specifically, such as Figure 5 As shown, a cleaning plate 6 is snapped onto the bottom of the mud storage box 31, and the surface of the cleaning plate 6 is coated with an anti-stick coating.

[0038] In this embodiment: by setting anti-slip texture, the friction between the friction wheel 33 and the pressure wheel is increased. By setting the depth of the anti-slip texture to 2-3mm, the friction between the friction wheel 33 and the pressure wheel is increased, effectively preventing slippage and ensuring that the friction wheel 33 can stably transmit power to the auger 32. By setting the cleaning plate 6, when a certain amount of residue accumulates in the mud storage box 31 and needs to be cleaned, the cleaning plate 6 can be easily removed to thoroughly clean the inside of the mud storage box 31. By setting the anti-stick coating, the residue can be prevented from adhering to the cleaning plate 6, further reducing the cleaning difficulty and improving the cleaning efficiency.

[0039] Working principle: First, the user connects the connecting frame 1 to the road roller using bolts and other connectors through the connecting hole 5. Then, when the road roller is working, the scraper 22 directly contacts the surface of the road roller's roller wheel, scraping away the soil, gravel, asphalt, and other residues adhering to the roller wheel surface with its sharp edge. The scraped residue enters the mud storage box 31 of the mud guiding mechanism 3 through the guide port 24. At the same time, the friction wheel 33, through contact with the road roller's roller wheel, uses the friction between the two to drive the auger 32 to rotate. The auger 32, through rotation, transports the residue in the mud storage box 31 from the left side to the mud discharge hole 34 on the right side. The mud discharge hole 34 discharges the residue from the mud storage box 31, maintaining the space inside the mud storage box 31. Finally, when a certain amount of residue accumulates in the mud storage box 31 and needs to be cleaned, the user separates the cleaning plate 6 from the mud storage box 31 to thoroughly clean the inside of the mud storage box 31. After cleaning, the user simply snaps the cleaning plate 6 back into the mud storage box 31.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
