Embodiment 1

[0070] Such as figure 1 As shown, the roller cleaning device of the present application includes a pilot wheel 100 , a floating lever 200 , a floating lever force assembly 300 , a trigger lever 400 , a trigger lever delay reset assembly 500 and a scraper assembly 600 .

[0071] The pilot wheel 100 plays a role in driving the floating lever 20 to rotate around its fulcrum after touching the sticky debris on the pressure roller 1; the pilot wheel 100 includes a pilot wheel main body 110 and a foundation wheel; the main body 110 of the pilot wheel is elliptical, and the midpoint position (center position, center of gravity) of the line connecting the two foci of the ellipse is rotatably and fixedly connected with one end of the floating lever 200; the basic wheel 120 It is rotatably and fixedly connected to the main body 110 of the pilot wheel, and the number of the basic wheels 120 is four, and the four basic wheels 120 are symmetrically arranged in pairs; The axial direction i...

Embodiment 2

[0081] Considering that during the operation of the pressure roller cleaning assembly of the road roller, the wear of the scraping plate 620 (the process of compensating the wear of the scraping plate 620 by the elastic body 630 extending from the scraping plate) will cause the continuous reduction of the pressure of the scraping plate on the surface of the pressure roller 1, thereby affecting The cleaning effect of the shovel plate 620 on debris (initially the pressure is higher and the cleaning effect is good but the shovel plate 620 wears faster, and then the pressure gradually decreases and the cleaning effect becomes worse); On the basis of the above, an elastic body elastic force adjustment device 631 is added to reduce the initial wear speed of the blade 620 while ensuring the cleaning effect by adjusting the compressed amount of the elastic body 630 protruding from the blade. Such as Figure 4 As shown, the elastic body elastic force adjusting device 631 includes the m...

Embodiment 3

[0086] During the actual application of the present application, it was found that the possibility of sticking materials in different areas on the pressure roller 1 is different, which in turn leads to different degrees of wear of the shovel plate 620 in different areas. Sometimes a shovel plate 620 is partially worn too severely and the entire shovel plate 620 needs to be replaced .

[0087] Such as Figure 5 As shown, in view of the above problems, this embodiment divides the entire pressure roller into multiple pressure roller partitions 11 and modularizes the shovel plate 620, and each pressure roller partition 11 corresponds to one shovel plate 620; when it is necessary to replace the shovel plate, only replace the severely worn one. The shovel plate 620.

[0088] The above-mentioned technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0089] The service life of the shovel plate 620 is further i...

Abstract

The invention discloses a cleaning device for a compression roller of a road roller. The cleaning device comprises a pilot wheel, a floating lever, a floating lever force application assembly, a trigger rod, a trigger rod delay reset assembly and a shovel plate assembly. After the pilot wheel touches sundries, the center height change of the pilot wheel is converted into acting force pointing to the trigger rod through the floating lever, the acting force is applied to the trigger rod, and the floating lever force application assembly resets the pilot wheel after the pilot wheel passes throughthe sundries; the stressed trigger rod generates axial displacement to drive the shovel plate assembly to rotate so as to extrude the shovel plate assembly to be attached to the surface of the pressing roller to clean up the adhered sundries, and after the sundries are cleaned up, the trigger rod is reset by the trigger rod delay reset assembly to wait for next triggering. The technical problemsin the prior art, a mud scraping plate for shoveling materials is high in abrasion speed, short in service life and high in replacement frequency are solved, the road roller can automatically recognize sundries needing to be removed on the pressing roller, the sundries adhering to the surface of the pressing roller are removed in a time-sharing mode, and then the technical effect of reducing shovel plate abrasion is achieved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a roller cleaning device for road rollers. Background technique [0002] Road roller, also known as soil compactor, is a kind of equipment for road construction; road roller belongs to the category of road equipment in construction machinery, and is widely used for filling compaction in large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. For practical operation, it can roll sandy, semi-cohesive and cohesive soil, roadbed stabilized soil and asphalt concrete pavement layer. With the gravity of the machine itself, the road roller is suitable for various compaction operations, so that the rolled layer can be permanently deformed and compacted. [0003] When the road roller is rolling on the soil layer, the surface of the roller will adhere to soil, clay and other materials. If the adhesion is not cleaned up in t...
