Abstract

The utility model relates to a novel crawler bulldozer, in particular to a comb-teeth working device of the crawler bulldozer. The existing working device of the bulldozer is generally a solid cambered structure formed by welding steel plates, can only finish the work of shovelling, pushing and raking and is hard to accomplish the operations of only raking out scrub, thorns, tree roots and the like and leaking out earth, weeds and other substances which do not need to be gotten rid off. A comb-teeth welding body of the comb-teeth working device consists of an upper part, a middle part and a lower part, wherein the upper part is a guardrail part preventing large branches, crotches and other substances from being raked out to damage the bulldozer, thereby playing the role of protecting the bulldozer; the middle part is an earth leaking and piling part and plays the role of raking out the branches and leaking out the earth, the weeds and the substances which do not need to be gotten rid off; and the lower part is a mainbody part and leads comb teeth to insert into the ground surface to clear and dig scrubs, thorns, tree roots and other substances embedded at certain depth, thereby playing the roles of cutting and earth leaking. The comb-teeth working device expands the range of application of the existing bulldozer.

Description
