Description

Technical Field

[0001] This utility model relates to the field of bulldozer blade technology, and in particular to a bulldozer blade structure. Background Technology

[0002] A bulldozer blade is a core working device in construction machinery used for bulldozing, leveling, and excavation. It is commonly used in conjunction with bulldozers, loaders, or tractors. In current technology, most bulldozer blades are mounted at the front of the equipment in the direction of travel, primarily used to shovel and push mud, sand, and stones forward. However, in some road grading operations—such as private driveway grading, shrub clearing, farmland soil leveling, and other backfilling projects—front-mounted bulldozer blades can leave ruts on the leveled road surface. Therefore, current technology typically uses rear-mounted bulldozer blades for road grading.

[0003] However, when existing rear-mounted bulldozer blades are used for road leveling, material overflows to both sides of the blade's working area, affecting the leveling effect. Furthermore, the connection structure between the bulldozer blade and the equipment is relatively complex, making it time-consuming and laborious to disassemble and assemble the bulldozer blade, which is not conducive to daily use by users. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a bulldozer blade structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a bulldozer blade structure, including an arc-shaped panel, a blade installed at the bottom of the arc-shaped panel, side baffles fixedly installed on both sides of the arc-shaped panel, an installation groove opened at the top of the arc-shaped panel, a connecting frame installed in the installation groove, a connecting plate fixedly installed at the top of the convex surface of the arc-shaped panel, a snap-fit ​​platform matching the connecting plate at the rear end of the connecting frame, a first pin hole opened in the middle of the connecting plate, a second pin hole opened at the rear end of the connecting frame, a first connecting pin installed between the first pin hole and the second pin hole, a third pin hole opened at the front end of the connecting frame, and a second connecting pin installed in the third pin hole.

[0006] Furthermore, the curved panel has bent portions at both ends, and several sets of first connecting through holes are opened near the edge of the bent portions. First fasteners are installed in the first connecting through holes, and the side baffle is fixedly installed on the side of the curved panel by the first fasteners.

[0007] Furthermore, the bottom end of the side baffle is provided with a support plate that bends outward, and the front end of the support plate is provided with a raised end.

[0008] Furthermore, a support frame is provided on the convex side of the arc-shaped panel. The support frame is fixedly installed at the bottom end of the bent portion. Several sets of second connecting through holes are opened at the bottom end of the arc-shaped panel. An inclined plate is provided on the side of the support frame near the arc-shaped panel. Several sets of third connecting through holes corresponding to the second connecting through holes are opened on the inclined plate. A second fastener is installed between each set of second connecting through holes and third connecting through holes. The scraper is fixedly installed on the arc-shaped panel by the second fastener.

[0009] The beneficial effects of this utility model are that the design of this utility model is to install side baffles on both sides of the arc-shaped panel. The side baffles extend to the concave side of the arc-shaped panel, and the side baffles and the arc-shaped panel form a box-shaped structure to prevent materials from overflowing to both sides, which is conducive to improving the leveling effect of the road. The connecting frame is connected to the mounting frame at the rear of the trailer through the second connecting pin, which improves the convenience of assembling and disassembling the bulldozer blade and is beneficial to the user's daily use.

[0019] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0020] according to Figure 1-7 As shown, a bulldozer blade structure includes an arc-shaped panel 1, a blade 2 fitted at the bottom of the arc-shaped panel 1, side baffles 3 fixedly installed on both sides of the arc-shaped panel 1, an installation groove 11 opened at the upper end of the arc-shaped panel 1, a connecting frame 4 fitted in the installation groove 11, a connecting plate 5 welded to the top of the convex surface of the arc-shaped panel 1, a snap-fit ​​platform 41 matching the connecting plate 5 at the rear end of the connecting frame 4, a first pin hole 51 opened in the middle of the connecting plate 5, a second pin hole 42 opened at the rear end of the connecting frame 4, a first connecting pin 6 fitted between the first pin hole 51 and the second pin hole 42, a third pin hole 43 opened at the front end of the connecting frame 4, and a second connecting pin 7 fitted in the third pin hole 43.

[0021] In this embodiment, the left and right ends of the arc panel 1 are provided with bending portions 12, and several sets of first connecting through holes 13 are provided near the edge of the bending portions 12. First fasteners 8 are installed in the first connecting through holes 13, and the side baffle 3 is fixedly installed on the side of the arc panel 1 by the first fasteners 8.

[0022] In this embodiment, the bottom end of the side baffle 3 is provided with a support plate 31 that bends outward, and the front end of the support plate 31 is provided with a curved end 32. When the trailer tows the bulldozer blade, the support plate 31 contacts the ground, preventing the blade 2 from inserting below the ground, which helps to improve the leveling effect. The curved end 32 is curved upward, and the bulldozer blade prevents the support plate 31 from scooping up the soil when it moves.

[0023] In this embodiment, a support frame 9 is provided on the convex side of the arc panel 1. The support frame 9 is fixedly installed at the bottom end of the bending part 12 by bolts. The support frame 9 supports the bottom ends of the two sets of bending parts 12, which helps to improve the strength of the bulldozer blade. Several sets of second connecting through holes 14 are opened at the bottom end of the arc panel 1. An inclined plate 91 is provided on the side of the support frame 9 near the arc panel 1. Several sets of third connecting through holes 92 corresponding to the second connecting through holes 14 are opened on the inclined plate 91. A second fastener 10 is installed between each set of second connecting through holes 14 and third connecting through holes 92. The blade 2 is fixedly installed on the arc panel 1 by the second fastener 10. The inclined plate 91 is flush with the side of the blade 2. The support frame 9 supports the nut of the second fastener 10, which improves the connection strength of the blade 2.

[0024] When in use, the side baffle 3 extends toward the concave side of the arc panel 1, forming a box-shaped structure between the side baffle 3 and the arc panel 1 to prevent materials from overflowing to both sides, which is beneficial to improving the leveling effect of the road. The connecting frame 4 is connected to the mounting frame at the rear of the trailer through the second connecting pin 7, which improves the convenience of disassembling and assembling the bulldozer blade and is beneficial to the user's daily use.

[0025] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
