Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and in particular to a scraper mounting structure for a bulldozer. Background Technology

[0002] A bulldozer is a heavy-duty construction machine primarily used for earthmoving operations, widely applied in construction, mining, road construction, and farmland improvement. Its main function is to use a scraper (also called a blade) at the front to perform tasks such as pushing soil, leveling the ground, excavating, filling, and clearing obstacles. The bulldozer scraper (also called a blade or bulldozer blade) is the main working device of the bulldozer, installed at the front, and used for pushing soil, leveling the ground, excavating, and filling. The design and performance of the scraper directly affect the bulldozer's working efficiency and applicable range.

[0003] Bulldozer scrapers are typically fixed to the bottom of the bulldozer using a fixed installation or welding method. While this installation method is simple and stable, it also has significant drawbacks. Bulldozer scrapers are usually made of high-strength wear-resistant steel, providing a certain degree of impact and wear resistance. However, when the scraper encounters hard rocks embedded in the road surface during bulldozing, the scraper experiences significant localized impact forces due to the tight bond between the rocks and the ground. This impact can not only cause dents and cracks on the scraper surface but also potentially lead to chipping or deformation of the scraper's cutting edge, and even affect the stability of the connection mechanism between the scraper and the bulldozer. Therefore, there is an urgent need for a new type of bulldozer scraper structure that can effectively reduce damage to the scraper from hard rocks while maintaining bulldozing efficiency, extending the scraper's service life, and reducing equipment maintenance costs.

[0004] The purpose of this utility model is to provide a scraper mounting structure for a bulldozer to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a scraper mounting structure for a bulldozer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scraper mounting structure for a bulldozer, comprising...

[0007] scraper body;

[0008] The connecting mechanism includes a first connecting rod and a second connecting rod symmetrically arranged on the top of the scraper body. The ends of the first connecting rod and the second connecting rod are rotatably connected to a connecting shaft. The ends of the first connecting rod and the second connecting rod are each provided with a second buffer part for buffering the impact force of stones on the scraper body. The top of the scraper body is symmetrically provided with a first buffer part for buffering the impact force of stones on the scraper body.

[0009] Furthermore, each first buffer section includes a sliding groove on the top of the scraper body, a sliding block is slidably connected in the sliding groove, and a second spring is provided on both sides of the sliding block, with the end of the second spring connected to the sliding groove.

[0010] Furthermore, each of the sliding grooves has symmetrically formed motion grooves inside, and a motion plate is slidably connected inside each of the motion grooves. A third spring is symmetrically arranged on both sides of the motion plate, and the end of the third spring is connected inside the motion groove.

[0011] Furthermore, the second buffer portion includes a connecting post disposed within the first connecting rod, and a first gear is disposed on the outer side of the connecting post, the first gear being meshed with a second gear.

[0012] Furthermore, a screw is threadedly connected to the outer side of the second gear, and a first spring is sleeved on the outer side of the screw. One end of the first spring is connected to a first rotating shaft, and the other end is connected to a second rotating shaft.

[0013] Furthermore, the first rotating shaft is rotatably connected to the first connecting rod, the second rotating shaft is rotatably connected to the second gear, and the connecting column passes through the first connecting rod and is connected to the sliding block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting a first buffer part, when the scraper body is impacted by a stone on the side, the scraper body will rotate, and the first buffer part will buffer it, reducing the impact of the stone on the scraper body. This has the advantage of greatly improving the impact force received by the scraper body.

[0016] 2. By setting a second buffer part, when the center of the scraper body collides with a stone and impacts the scraper body, the first connecting rod and the second connecting rod will open, and the first buffer part will buffer it. As a result, the first gear and the second gear in the second buffer part will rotate, and the second spring will slow down the rotation speed of the second gear, thereby buffering. The advantage of this is that it effectively reduces the damage of hard stones to the scraper and extends the service life of the scraper. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] Please see Figures 1 to 5 As shown, a scraper mounting structure for a bulldozer includes a scraper body 1;

[0030] The connecting mechanism includes a first connecting rod 2 and a second connecting rod 4 symmetrically arranged on the top of the scraper body 1. A connecting shaft 3 is rotatably connected to the end of the first connecting rod 2 and the end of the second connecting rod 4. Both the first connecting rod 2 and the second connecting rod 4 have a second buffer part 6 at their ends to buffer the impact force of stones on the scraper body 1. The second buffer part 6 includes a connecting post 7 disposed within the first connecting rod 2. A first gear 8 is disposed on the outside of the connecting post 7, and the first gear 8 is meshed with a second gear 9. A screw 10 is threadedly connected to the outside of the second gear 9. A first spring 12 is sleeved on the outside of the screw 10, and one end of the first spring 12 is connected to a first rotating shaft 11. The first rotating shaft 11 ensures that the rotation of the screw 10 is not affected. The other end is connected to the second rotating shaft 13, which ensures that the rotation of the second gear 9 is not affected. The first rotating shaft 11 is rotatably connected to the first connecting rod 2, and the second rotating shaft 13 is rotatably connected to the second gear 9. The connecting post 7 passes through the first connecting rod 2 and is connected to the sliding block 17. The sliding block 17 drives the connecting post 7 to move, thereby driving the first gear 8 to rotate, which in turn drives the second gear 9 to rotate. As a result, the second gear 9 moves up and down on the outside of the screw 10, thereby stretching or compressing the first spring 12 to buffer the impact force.

[0031] The top of the scraper body 1 is symmetrically provided with first buffer parts 5 for buffering the impact force of stones on the scraper body 1. Each first buffer part 5 includes a sliding groove 14 opened on the top of the scraper body 1. A sliding block 17 is slidably connected in the sliding groove 14. A second spring 16 is provided on both sides of the sliding block 17. The end of the second spring 16 is connected to the sliding groove 14. A moving groove 15 is symmetrically opened inside the sliding groove 14. A moving plate 18 is slidably connected in the moving groove 15. A third spring 19 is symmetrically arranged on both sides of the moving plate 18. The end of the third spring 19 is connected to the moving groove 15. The sliding block 17 drives the moving plate 18 to move in the moving groove 15 in the sliding groove 14, thereby compressing or stretching the second spring 16 and the third spring 19, thereby reducing the impact force on the scraper body 1.

[0032] Working principle: When the scraper body 1 is subjected to a lateral impact force, the scraper body 1 will rotate, thereby driving the first connecting rod 2 and the second connecting rod 4 to move. In turn, the first connecting rod 2 and the second connecting rod 4 drive the sliding block 17 to move in the sliding groove 14, thereby driving the moving plate 18 to move in the moving groove 15. As a result, the second spring 16 and the third spring 19 are compressed or stretched, thereby reducing the impact force of the stone on the scraper body 1. When the center of the scraper body 1 is subjected to an impact force, the connecting column 7 rotates, thereby driving the first gear 8 to rotate, which in turn drives the second gear 9 meshing with it to rotate. Since the second gear 9 is internally threaded with a screw 10, the second gear 9 moves up and down, thereby driving the second rotating shaft 13 to stretch or compress the first spring 12, thereby changing the rotation speed of the second gear 9, thereby buffering the impact force on the scraper body 1. The scraper body 1 moves, thereby opening the first connecting rod 2 and the second connecting rod 4, and simultaneously buffering the impact force on the scraper body 1.
