Description
Technical field
The utility model is related to clean-up scrapers after a kind of land leveller, belong to technical field of engineering machinery.
Background technology
Land leveller can also carry out the smooth of macadam pavement and pave other than the soil property evenness of road surface of conventional highways at different levels,
Pavement preservation is especially carried out using land leveller in surface mine, to protect the tire of mine heavy mobile service, reduces tire
Abrasion and scuffing.The maintenance of macadam pavement, it is not high to smooth required precision, but the grain size of rubble and Media density are all bigger,
And smooth area is big, it is serious to blade abrasion.Same work surface generally requires to carry out smooth maintenance twice back and forth, and cleaning first is big
Type rubble, then road pavement secondary maintenance.Moreover, the stone that still has indivedual grain sizes larger of the road surface after smooth is exposed on surface,
Easily the equipment tire of traveling is caused to scratch.The rear ridge buster major function of conventional land leveling machine configuration is the loose hard surfacing of rake,
Cleaning and smooth effect very little to macadam pavement, this results in land leveller when macadam pavement is smooth, round-trip repeatedly work, effect
Rate is low, and blade abrasion is serious, and the replacement cycle is fast, at the same it is smooth after road surface still have the skimble-scamble ratchel of grain size exposed in table
Face causes traveling tire to scratch.
