[0001] The utility model relates to a mud scraping plate, concretely relates to a road roller mud scraping plate device, belongs to the accessory equipment technical field of road roller, especially single steel wheel road roller. BACKGROUND
[0002] During the working process of the road roller, the steel wheel will generate great pressure on the soil, asphalt and other paving materials on the roadbed, so that the roadbed is flattened and compacted by the steel wheel. The steel wheel reciprocates and contacts the soil and asphalt on the roadbed, which causes the soil and other materials to easily adhere to the working surface of the steel wheel. Especially when the soil, asphalt and sandstone are attached to the working surface of the steel wheel, it will affect the subsequent compaction effect, because the sandstone will form a groove on the roadbed together with the steel wheel, thereby affecting the flatness of the roadbed. The road roller in the prior art generally uses a mud scraping plate to solve the above problems, but the mud scraping plate needs to be cleaned frequently and timely to prevent the accumulation and retention of sundries. If the sundries accumulate too much, they will fall on the working path of the steel wheel beyond the baffle, which may still cause the above problems. Therefore, it is necessary to design a mud scraping plate device that can remove the sundries attached to the steel wheel and clean the mud scraping plate in time, so that the sundries fall outside the working path of the steel wheel and do not affect the normal road rolling process.

[0021] Referring to Figures 1-3
[0022] A road roller mud scraping plate device, comprising a single steel wheel 1; the single steel wheel 1 is provided with main supports 2 on both sides; the main supports 2 are connected with the body of the road roller, and the main supports 2 on both sides are respectively provided with stands 3; a scraper seat 4 is arranged between the two stands 3; a propelling mechanism is arranged in the scraper seat 4; one side of the propelling mechanism is connected with a driving part; the main supports 2 are further provided with a mud guide plate 5.
[0023] Further, the scraper seat 4 comprises a vertical baffle 4-1 and an inclined bottom plate 4-2; one side of the inclined bottom plate 4-2 is close to the outer peripheral surface of the steel wheel 1; and the two ends of the vertical baffle 4-1 are respectively connected with the stands 3.
[0024] Further, the propelling mechanism comprises a propelling screw 6 arranged between the vertical baffle 4-1 and the inclined bottom plate 4-2; rotating shaft holes are respectively formed in the two stands 3 opposite to the propelling screw 6; and the two ends of the propelling screw 6 are respectively connected in the rotating shaft holes.
[0025] Further, the driving part is a driving motor 7; the driving motor 7 is arranged outside the stands 3; and the output shaft of the driving motor 7 is connected with the propelling screw 6.
[0026] Further, the length of the vertical baffle 4-1 and the inclined bottom plate 4-2 is greater than the axle length of the single steel wheel 1; the inclined bottom plate 4-2 has a mud outlet end 8; the mud outlet end 8 is located at the end of the propulsion direction of the propulsion screw 6; the mud outlet end 8 is outside the axle length range of the single steel wheel 1.
[0027] The mud outlet end 8 in the embodiment is actually the position where the mud, sand and other sundries move along the inclined bottom plate 4-2 under the action of the propulsion screw 6 and finally drop down on the guide plate 5
[0028] Further, the upper end of the guide plate 5 is connected to the mud outlet end 8; the inner side of the guide plate 5 is close to the end surface of the single steel wheel 1, and the outer side is located outside the main support 2.
[0029] Further, the guide plate 6 is arranged in a high inside and low outside manner; the guide plate 6 covers the gap between the main support 2 and the single steel wheel 1; the mud drops directly from the circumferential surface of the single steel wheel to the guide plate and slides down.
[0030] Further, the bottom end of the inclined bottom plate 4-2 is detachably connected with a rubber strip 9; the two ends of the inclined bottom plate 4-2 are rotationally connected with the stand column 3; the inner side of the inclined bottom plate 4-2 is provided with a hinge seat 10; the inner side of the stand column is provided with a pneumatic cylinder 11; the pneumatic cylinder 11 is connected with a push rod 12; the other end of the push rod 12 is connected with the hinge seat 10.
[0031] Specifically, when the pneumatic cylinder 11 works, the push rod 12 is pushed to move horizontally; since the end of the push rod 12 is hinged with the hinge seat 10, the push rod 12 will drive the inclined bottom plate 4-2 to overturn upward; after the inclined bottom plate 4-2 overturns upward, the rubber strip 9 will be tightly attached to the single steel wheel 1, and cooperates with the rolling of the single steel wheel 1 to scrape the sundries on the surface.
[0032] Working principle: when the single steel wheel 1 drives the mud, sand and other sundries to rotate to the position close to the inclined bottom plate 4-2, most of the mud will be scraped from the single steel wheel 1 due to the action of the inclined bottom plate 4-2; since the gap between the inclined bottom plate 4-2 and the single steel wheel 1 is very small, the scraped sundries cannot drop down but only stay between the inclined bottom plate 4-2 and the vertical baffle 4-1; at this time, the driving motor 7 is started to open the propulsion screw 6, which drives all the sundries to move along the direction of the inclined bottom plate 4-2 under the action of the propulsion screw 6; when the sundries move to the position outside the axle line of the single steel wheel 1, that is, to the mud outlet end 8, the sundries will enter the guide plate 5, and slide to the position outside the main support 2 under the guidance of the guide plate 5.
[0033] Meanwhile, if the amount of attached soil is extremely large, especially in the case of clay. When it is subjected to the action of the inclined bottom plate 4-2, it is easy to deform and then fall out from both sides of the steel wheel 1. It cannot be guided and discharged by the mud guide plate 5 after entering the inclined bottom plate 4-2. In this case, the length of the mud guide plate 5 can be increased so that the mud guide plate 5 can cover the edge of the steel wheel 1 to receive the soil falling from both sides of the steel wheel 1. In short, since the mud guide plate 5 adopts the design of high inside and low outside, no matter where the sundries are received, they can be guided to the outside of the main support 2. They will not fall on the movement path of the steel wheel 1.
[0034] Finally, it is pointed out that the above embodiments are only to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. They should be covered in the scope of the claims of the present application.
