AI Technical Summary
When existing tractor bulldozer blades are pushing soil, the soil piles up in front of the bucket, increasing the resistance to movement and thus increasing fuel consumption.
An improved tractor bulldozer blade was designed, which uses a hydraulic cylinder and connecting structure to adjust the tilt of the blade body, pushing the soil pile to one side and reducing travel resistance.
By tilting and adjusting the soil pile, the resistance of the tractor during travel is reduced, thereby reducing fuel consumption.

Abstract
Claims
1. An improved bulldozing blade of a tractor comprising a bulldozing blade body (1), a connecting frame (2) for mounting said bulldozing blade body (1), and a hinged lug (3) welded on said connecting frame (2), characterized in that: The back of the bulldozer blade body (1) is horizontally fixedly connected to a limiting beam (4), and the limiting beam (4) is longitudinally symmetrically welded with a first connecting lug (5), and a connecting seat (6) is welded to one side of the limiting beam (4). The connecting frame (2) has a second connecting ear (7) longitudinally symmetrically welded to one end of the connecting seat (6), and the connecting seat (6) rotates in coordination with the second connecting ear (7); The connecting frame (2) is welded to one end of the limiting crossbeam (4) with a limiting channel steel (9); The connecting frame (2) has a third connecting ear (10) longitudinally and symmetrically welded to the side wall near the first connecting ear (5). A hydraulic cylinder (12) is installed between the third connecting ear (10) and the first connecting ear (5). A first connecting head (13) and a second connecting head (14) are respectively installed at both ends of the hydraulic cylinder (12), and the first connecting head (13) and the second connecting head (14) are rotatably connected to the third connecting ear (10) and the first connecting ear (5) respectively.
2. An improved tractor dozer blade as claimed in claim 1 wherein: The first connecting ear (5) is equipped with a first pin (15) that is connected to the second connector (14), and the outer diameter of the first pin (15) is adapted to the inner diameter of the second connector (14).
3. The improved tractor dozer blade as claimed in claim 1 wherein: The second connecting ear (7) is equipped with a second pin (8) that is connected to the connecting seat (6).
4. An improved tractor dozer blade as claimed in claim 3 wherein: The connecting seat (6) has a through-hole, and the inner diameter of the through-hole is adapted to the outer diameter of the second pin (8).
5. The improved tractor dozer blade as claimed in claim 1 wherein: The limiting channel steel (9) and the limiting crossbeam (4) form an embedded structure.
6. The improved tractor dozer blade as claimed in claim 1 wherein: The third connecting ear (10) is equipped with a third pin (11) that is connected to the first connector (13), and the outer diameter of the third pin (11) is adapted to the inner diameter of the first connector (13).
7. The improved tractor dozer blade as claimed in claim 1 wherein: The connecting frame (2) has mounting holes symmetrically installed at the end away from the bulldozer blade body (1).
