Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, and a kind of reversible bulldozer perching knife that does not need to change bulldozer operating position can flexible transformation perching knife direction is provided, and this scheme is simple to operate simultaneously, and operating efficiency is high.
This programme is achieved by the following technical measures: a kind of reversible bulldozer perching knife of the present utility model, comprise perching knife and segmental support, it is characterized in that: the rotating centre position that is arranged on segmental support front end of described perching knife, this perching knife is made up of left perching knife and right perching knife, between left perching knife and right perching knife, be flexibly connected, left perching knife back is provided with left hinged seat, right perching knife back is provided with right hinged seat, described segmental support left side is provided with left change shovel hydraulic cylinder, segmental support right side is provided with right change shovel hydraulic cylinder, the expansion link of left change shovel hydraulic cylinder is fixedly connected with left hinged seat, the expansion link of right change shovel hydraulic cylinder is fixedly connected with right hinged seat.
Reversible bulldozer perching knife of the present utility model, it further improves and is: described segmental support left-hand portion is also provided with left lift cylinder, and position, segmental support right side is provided with right lift cylinder.
Reversible bulldozer perching knife of the present utility model, it further improves and is: described left lift cylinder is positioned at the side of left change shovel hydraulic cylinder away from left perching knife, and described right lift cylinder is positioned at the side of right change shovel hydraulic cylinder away from right perching knife.
Reversible bulldozer perching knife of the present utility model, it further improves and is: between described left perching knife and right perching knife, be flexibly connected by bearing pin.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due in this scheme, the rotating centre position that is arranged on segmental support front end of perching knife, and perching knife is divided into left perching knife and right perching knife, between left perching knife and right perching knife, be flexibly connected by bearing pin, left perching knife is connected with left change shovel hydraulic cylinder by left hinged seat, right perching knife is connected with right change shovel hydraulic cylinder by right hinged seat, realize the flexible transformation of angle between left perching knife and right perching knife and bulldozer direct of travel, in the traveling process of bulldozer, do not need to adjust its direction of advance, just can be easily by native stone, accumulated snow, other material is pushed into the one or both sides of bulldozer, improve operating efficiency, reduce operating cost.In addition, in the process of transportation bulldozer, perching knife can be turned up, reduce the shared space of perching knife, reduce freight, play the effect of cost efficiency.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
