Description

Technical Field

[0001] The utility model relates to the technical field of road roller equipment, and more specifically, it relates to a soil scraping device for a road roller. Background Art

[0002] A road roller, also known as a soil compactor, is a device for road construction. Road rollers belong to the category of road equipment in construction machinery and are widely used for the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-viscous, and viscous soils, subgrade stabilized soils, and asphalt concrete pavement layers. Road rollers use the gravity of the machine itself and are suitable for various compaction operations, causing the compacted layer to undergo permanent deformation and become dense. Road rollers are divided into two categories: steel wheel type and tire type.

[0003] Currently, the Chinese patent with the application number 201720174967.0 on the market discloses a scraping device for a road roller, which includes a fixed frame body and a steel wheel rotatably arranged on the fixed frame body. A rotating rod parallel to the axial direction of the steel wheel is rotatably connected to the fixed frame body. A scraper that abuts against the side wall of the steel wheel and extends along the axial direction of the rotating rod is arranged on the rotating rod. A linkage member for driving the rotating rod to rotate is connected between the rotating rod and the steel wheel.

[0004] In the above patent, although by setting a rotating rod on the fixed frame body and arranging the scraper on the rotating rod, the rotating rod can drive the scraper to rotate and clean the particulate matter, thereby reducing the entry of particulate matter between the scraper and the steel wheel and extending the service life of the scraper and the steel wheel. However, when the scraper scrapes off the soil and drops it to the ground, it is still easy for the soil to adhere to the pressing wheel again during the driving process of the road roller, affecting the scraping and cleaning effect of the soil adhering to the pressing wheel.

Detailed Embodiment

[0017] Refer to Figures 1 to 3 for further description of the embodiments of the present utility model.

[0018] A soil scraping device for a road roller includes a road roller body 1, a fixing frame 2, a pressing wheel 3, a collecting mechanism 5 and a scraping mechanism 4. The road roller body 1 is fixedly connected to the fixing frame 2. The pressing wheel 3 is installed on the fixing frame 2. The collecting mechanism 5 is movably connected to the fixing frame 2. The scraping mechanism 4 is fixed to the fixing frame 2.

[0019] The collecting mechanism 5 includes a storage box 51, a material guiding plate 52, a connecting block 53, a positioning plate 54, a hook 55 and a fixing rod 56. The material guiding plate 52 is fixedly arranged on the storage box 51 in an inclined shape. The positioning plate 54 is fixedly arranged on the fixing frame 2 in a U shape, and the storage box 51 is placed on the positioning plate 54. Connecting blocks 53 are arranged on both sides of the storage box 51. The fixing rod 56 is fixedly arranged on the connecting block 53 in a U shape. Hooks 55 are arranged on both sides of the fixing frame 2, and the hooks 55 are clamped with the fixing rods 56.

[0020] The scraping mechanism 4 scrapes the soil on the pressing wheel 3, and then the scraped soil falls onto the material guiding plate 52 and is moved into the storage box 51 through the material guiding plate 52 for collection, preventing the soil from scattering on the ground and reducing the possibility of the soil adhering to the pressing wheel 3 again.

[0021] The scraping mechanism 4 includes a scraping plate 41, a baffle plate 42, a spring 43, a slider 44, a telescopic rod 45 and a limiting member 46. The two ends of the telescopic rod 45 are respectively fixedly connected to the fixing frame 2 and the baffle plate 42. The scraping plate 41 is fixed to the baffle plate 42. A plurality of through holes 13 are formed in the scraping plate 41. The spring 43 is sleeved on the telescopic rod 45, and the two ends of the spring 43 respectively abut against the fixing frame 2 and the baffle plate 42. A sliding groove 6 is formed in the fixing frame 2. The slider 44 is placed in the sliding groove 6 and slides. The slider 44 is fixedly connected to the baffle plate 42. The limiting member 46 is placed on the fixing frame 2 and cooperates with the slider 44.

[0022] The scraping plate 41 scrapes the surface of the pressing wheel 3, and then scrapes the soil on the surface of the pressing wheel 3 and accumulates it on the scraping plate 41. The soil accumulated on the scraping plate 41 falls onto the material guiding plate 52 through the through holes 13 in the scraping plate 41 and flows into the collection box. By providing the spring 43, when the scraping plate 41 is temporarily deformed or displaced due to contacting the soil on the pressing wheel 3, the spring 43 can use its elasticity to reset the scraping plate 41 to the original position, ensuring that the scraping plate 41 can work continuously and effectively.

[0023] When not needed, by moving the baffle plate 42, the baffle plate 42 drives the slider 44 to move in the sliding groove 6. At the same time, the baffle plate 42 drives the scraping plate 41 away from the pressing wheel 3, and then cooperates with the limiting member 46 to fix the slider 44 in the sliding groove 6 and fix the scraping plate 41 at the same time.

[0024] The limiting member 46 includes a lead screw 7, a knob 8 and a fixing block 9. A first positioning groove 10 is formed on the fixing frame 2. The first positioning groove 10 communicates with the sliding groove 6. A second positioning groove 11 corresponding to the first positioning groove 10 is formed on the sliding block 44. The knob 8 is rotatably connected to the fixing frame 2. The lead screw 7 is placed in the first positioning groove 10. The lead screw 7 is fixedly connected to the knob 8. The fixing block 9 is placed in the first positioning groove 10. A threaded hole 12 is formed on the fixing block 9. The lead screw 7 passes through the threaded hole 12 and is threadedly connected to the threaded hole 12;

[0025] By sliding the sliding block 44, the sliding block 44 slides in the sliding groove 6 until the second positioning groove 11 on the sliding block 44 corresponds to the first positioning groove 10 on the fixing frame 2. Then, by rotating the knob 8, the knob 8 drives the lead screw 7 to rotate. Furthermore, the lead screw 7 drives the fixing block 9 into the second positioning groove 11. Until one end of the fixing block 9 extends into the second positioning groove 11, the sliding block 44 is fixed in the sliding groove 6, and at the same time, the scraper 41 is moved away from the pressure wheel 3 when not working, preventing the scraper 41 from contacting the pressure wheel 3 for a long time and shortening the service life.

[0026] Working principle: When rolling the road, the pressure wheel 3 rotates to drive the scraper 41 to contact the surface of the pressure wheel 3. Then, the scraper 41 scrapes the soil on the surface of the pressure wheel 3, and the scraped soil is piled up on the scraper 41. Then, it flows through the through hole 13 on the scraper 41 to the material guiding plate 52. Then, due to the inclined shape of the material guiding plate 52, the scraped soil rolls into the storage box 51 for collection. When the storage box 51 is full, by removing the fixing rods 56 at both ends of the storage box 51 from the hooks 55, the storage box 51 is removed from the positioning plate 54. Then, after pouring out the soil in the storage box 51, it is reinstalled on the fixing frame 2;

[0027] When the road roller body 1 is not working, by sliding the baffle 42, the baffle 42 drives the scraper 41 and the sliding block 44 to move respectively. The sliding block 44 moves in the sliding groove 6 until the second positioning groove 11 on the sliding block 44 corresponds to the first positioning groove 10 on the fixing frame 2. Then, by rotating the knob 8, the lead screw 7 rotates in the threaded hole 12 of the fixing block 9, and then pushes the fixing block 9 to move in the first positioning groove 10 until one end of the fixing block 9 extends from the first positioning groove 10 into the second positioning groove 11, thereby fixing the sliding block 44 in the sliding groove 6 and at the same time moving the scraper 41 away from the pressure wheel 3.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
