Description

Technical Field

[0001] The utility model belongs to the technical field of bulldozers, in particular to a vibrating bulldozer blade. Background Art

[0002] A bulldozer is an engineering vehicle with a large metal blade in front of it. When in use, the blade is lowered to shovel and push mud, sand, stones, etc. forward. The position and angle of the blade can be adjusted, and it can complete the work of digging, transporting and unloading soil alone. The bulldozer has the characteristics of flexible operation, easy rotation, small working surface and fast driving speed. When the bulldozer is working, the blade is not only worn by mud and sand, but also by the impact during stone operations and auxiliary shoveling operations. Therefore, the blade is required to be wear-resistant and have high strength.

[0003] In view of the existing patent CN201520397733.3, a vibrating bulldozer blade is provided, in which the interior of the device adopts an overlapping arrangement of an arc-shaped panel and an arc-shaped mounting plate, and cooperates with upper and lower U-shaped beams to increase rigidity, have good stability, and have a compact and reasonable structure; reduce welding procedures, improve processing technology, reduce processing intensity and manufacturing costs, and have good overall economic performance. The utility model inserts a cutter body into the insert body, and the vibrator directly loads the vibration force onto the cutter body, which effectively improves the shoveling effect of the blade when bulldozing, and solves the technical problem of low efficiency that when the bulldozer encounters a block of soil that is difficult to shovel during operation, it needs to adjust the bulldozer many times to achieve the purpose. However, the blade, as the main working device of the bulldozer, needs to withstand a relatively severe working load, and often encounters loose and hard materials such as sand and ore during work. At this time, when the blade is working, the shovel plate is the first to contact the material, and separates the material from the ground and loads it into the hopper. In this process, greater wear is caused to the upper and lower surfaces of the shovel plate, which reduces the working efficiency of the entire shovel. The existing repair method is to replace the shovel blade or weld a wear-resistant plate on the shovel plate. Although this can also solve the problem, it will make the entire device bulky and replace the shovel blade. It is more wasteful of resources. Utility Model Content

[0023] It should be noted that, since the upper and lower surfaces of the existing shovel plate will cause great wear when working, the working efficiency of the entire shovel blade is reduced, and the repair method is to replace the shovel blade or weld a wear-resistant plate on the shovel plate. Although this can solve the problem, it will make the entire device heavier and replacing the shovel blade will waste more resources. Therefore, in order to solve the problem that the working surface of the existing shovel plate will cause great wear, the repair method is to replace the shovel blade or weld a wear-resistant plate on the shovel plate. This will make the entire device heavier and replacing the shovel blade will waste more resources. The present solution is provided with a mounting part 4, so that the wear-resistant layer 13 is easy to replace. When the wear-resistant layer 13 is severely damaged, the wear-resistant layer 13 can be replaced, thereby avoiding the replacement of the hopper 1.

[0024] Specifically, in the present embodiment, the present solution mainly realizes that the wear-resistant layer 13 is easy to replace by providing a mounting member 4. When the wear-resistant layer 13 is seriously damaged, the wear-resistant layer 13 can be replaced, thereby avoiding the function of replacing the material hopper 1. When the material falls into the material hopper 1 after passing through the shovel plate 5, the push plate 11 will be seriously worn after continuous shoveling and pouring. In order to reduce the wear of the push plate 11 during operation, the push plate 11 is covered with a wear-resistant layer 13. The wear-resistant ridges 131 and bolts on the wear-resistant layer 13 can increase the structural strength and wear resistance of the wear-resistant layer 13 by using the wear-resistant ridges 131. After the wear-resistant ridges 131 are worn, it is convenient to replace the wear-resistant ridges 131. The wear convex strip 131 is replaced, and the wear-resistant layer 13 is detachably mounted on the push plate 11 to protect the push plate 11. The splicing seat 2 is docked with the splicing groove 112. When the splicing seat 2 is accommodated in the splicing groove 112, the block 46 first abuts against the splicing groove 112, causing the block 46 to shrink. When the block 46 slowly moves to one side of the slot 111, the side wall of the slot 112 applies pressure to the block 46. When the block 46 is completely moved into the slot 111, the block 46 can be engaged in the slot 111, so that the wear-resistant layer 13 is easy to replace. When the wear-resistant layer 13 is severely damaged, the wear-resistant layer 13 can be replaced, avoiding the need to replace the hopper 1.

[0025] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a shovel plate 5 is provided on the outer side of the lower end of the push plate 11, and a support plate for fixed connection is provided below the shovel plate 5.

[0026] In this embodiment, the strength of the scraper plate 5 is increased to improve the wear resistance.

Bolts for fixing the wear-resistant convex strip 131 are threadedly connected on the surface of the strip groove.

[0028] In this embodiment, the wear-resistant convex strips 131 can be easily replaced by the provided bolts after the wear-resistant convex strips 131 are worn.

[0029] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the number of the strip grooves and the wear-resistant convex strips 131 are both multiple, and the multiple wear-resistant convex strips 131 are equidistantly arranged on the front side of the wear-resistant layer 13 .

[0030] In this embodiment, the structural strength and wear resistance of the wear-resistant layer 13 can be increased by using the strip grooves, the wear-resistant convex strips 131 and the bolts on the wear-resistant layer 13 and the wear-resistant convex strips 131 .

[0031] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the shape of the insertion end of the clamping block 46 and the shape of the inner wall of the clamping slot 111 are both arc-shaped, and a groove is formed at the insertion end of the clamping block 46, and a ball 47 is movably installed inside the groove.

[0032] In this embodiment, the groove and the ball 47 are provided so that when the slot 111 squeezes the block 46, the ball 47 and the inner wall of the slot 111 roll and fit together, thereby reducing the friction between the block 46 and the slot 111 and reducing the wear of the block 46 caused by friction.
