Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, and in particular to a steel wheel structure for a road roller. Background Technology
[0002] A road roller, also known as a soil compactor, is a type of road construction equipment. Within the category of construction machinery, road rollers fall under the category of road equipment and are widely used in the compaction of fill sections in large-scale engineering projects such as highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-cohesive, and cohesive soils, as well as stabilized subgrade soils and asphalt concrete pavement layers. Road rollers utilize their own weight to perform various compaction operations, causing permanent deformation and densification of the compacted layer. Road rollers are further divided into two categories: steel-wheeled and pneumatic-wheeled.
[0003] Existing steel wheel rollers use scrapers to remove soil from the surface of the steel wheel. However, the scraped soil usually falls in front of the steel wheel, causing it to re-adhere to the surface of the steel wheel, thus reducing the efficiency of soil removal. Therefore, there is an urgent need for a steel wheel structure for rollers that can solve the problem of soil re-adhesion to the surface of the steel wheel after scraping. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a steel wheel structure for a road roller that can solve the problem of soil re-adhering to the surface of the steel wheel after scraping.

[0007] A steel wheel, which is rotatably connected between the two side plates;
[0008] The conveyor box is connected to the horizontal plate. The upper part of the conveyor box has an opening that is connected to the end of the first ramp. The conveyor box has a rotatable shaft with helical blades. The shaft is oriented in the Y direction. A first drive motor is installed on one outer wall of the conveyor box. The first drive motor is connected to the shaft. The side of the conveyor box away from the first drive motor has a discharge port.
[0009] The scraper is inclinedly connected to the horizontal plate by an elastic mechanism. The higher end of the scraper abuts against the surface of the steel wheel, and the lower end of the scraper is located above the higher end of the first slope.

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0026] Please refer to Figures 1 to 3 A steel wheel 2 structure for a road roller, comprising:
[0027] Frame 1, which includes side plates 11 and cross plates 12. The cross plates 12 are connected to one end of the two side plates 11, and a first ramp 121 is provided on the cross plates 12.
[0028] Steel wheel 2 is rotatably connected between the two side plates 11;
[0029] The conveyor box 3 is connected to the horizontal plate 12. The upper part of the conveyor box 3 is provided with an opening 31, which is connected to the end of the first ramp 121. The conveyor box 3 is provided with a rotatable shaft 32, and the shaft 32 is provided with a spiral blade 33. The axis of the shaft 32 is Y. A first drive motor 34 is provided on one outer wall of the conveyor box 3. The first drive motor 34 is connected to the shaft 32 in a transmission. The side of the conveyor box 3 away from the first drive motor 34 is provided with a discharge port 35.
[0030] The scraper 4 is inclinedly connected to the horizontal plate 12 through the elastic mechanism 5. The higher end of the scraper 4 abuts against the surface of the steel wheel 2, and the lower end of the scraper 4 is located above the higher end of the first slope 121.
[0031] In the above embodiments, after the steel wheel 2 performs compaction, the soil adheres to the surface of the steel wheel 2. The soil on the surface of the steel wheel 2 is scooped up by the higher end of the scraper 4, and the scooped soil falls into the first slope 121 through the scraper 4. Then, the soil falls into the conveying box 3 through the first slope 121. After the first drive motor 34 is turned on, the soil in the conveying box 3 is transported to the discharge port 35 through the rotating shaft 32 and the spiral blade 33. The soil falls from the discharge port 35 to the outside of one side of the steel wheel 2, so that the soil will not be re-adhered to the surface of the steel wheel 2. Compared with the prior art, by setting up the scraper 4, the first slope 121, the conveying box 3, the first drive motor 34, the rotating shaft 32 and the spiral blade 33, the soil scraped off by the steel wheel 2 can be transported to one side of the steel wheel 2, so that the steel wheel 2 will not be re-adhered to the scraped soil, solving the problem of soil re-adhering to the surface of the steel wheel 2 after scraping, and improving the scraping effect.
[0032] As an optional implementation, the elastic mechanism 5 includes a plurality of springs 51 arranged along the Y direction. The axial direction of the springs 51 is vertical. One end of the springs 51 is connected to the horizontal plate 12, and the other end of the springs 51 is connected to the lower part of the scraper 4.
[0033] In the above embodiments, by setting several springs 51, the scraper 4 can always be in contact with the surface of the steel wheel 2, thereby improving the scraping effect.
[0034] As an optional implementation, baffles 41 are provided on both sides of the scraper 4 in the Y direction, and a pivot shaft 42 is provided near the lower end of the scraper 4 on the baffle 41, with the axis of the pivot shaft 42 being in the Y direction.
[0035] In the above embodiments, by setting baffle 41, soil can be prevented from falling from both sides of scraper 4 in the Y direction into the front of steel wheel 2. By setting pivot shaft 42, scraper 4 can be stably attached to the surface of steel wheel 2.
[0036] As an optional implementation, a cleaning device 6 is provided on the upper part of the side plate 11. The cleaning device 6 includes a fixed frame 61, a water tank 66, a lead screw shaft 62, a slider 63, a second drive motor 64, a water pipe 65, a hose 67, a first trigger switch 68, and a second trigger switch 69. It is fixedly connected to the upper part of the side plate 11. The lead screw shaft 62 is connected inside the fixed frame 61, and the axis of the lead screw shaft 62 is in the Y direction. The slider 63 is slidably connected to the lead screw shaft 62. The water pipe 65 is connected to the lower part of the slider 63, and the axis of the water pipe 65 is in the Y direction. A nozzle 651 is provided at the lower part of the water pipe 65, and the nozzle 651 faces the scraper 4. The water tank 66 is connected to the upper part of the slider 63. One end of the hose 67 is connected to the water tank 66, and the other end of the hose 67 is connected to the water pipe 65. The first trigger switch 68 is located on the Y-direction side of the fixed frame 61, and the second trigger switch 69 is located on the opposite side of the Y-direction side of the fixed frame 61. The second drive motor 64 is drivenly connected to the lead screw shaft 62.
[0037] In the above embodiment, the water tank 66 is connected to the water pipe 65 via the hose 67. Then, the second drive motor 64 is turned on, and the water tank 66, water pipe 65, and nozzle 651 are used to rinse the scraper 4 below to prevent dirt from sticking to the scraper 4. Then, when the slider 63 touches a trigger switch, the second drive motor 64 reverses, causing the slider 63 to move along the Y direction. When the slider 63 touches the second trigger switch 69, the second drive motor 64 rotates forward, causing the slider 63 to move in the opposite direction along the Y direction. This allows the slider 63 to move back and forth on the lead screw shaft 62, thereby rinsing the dirt off the scraper 4.
[0038] As an optional implementation, the discharge port 35 is provided with a second ramp 351, the end of the second ramp 351 facing the Y-direction side.
[0039] In the above embodiments, the soil in the conveying box 3 can be guided to one side of the steel wheel 2 more smoothly.
[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
