Description

Technical Field

[0001] The invention relates to the technical field of bulldozer blades, in particular to a bulldozer blade and a protective structure thereof. Background Art

[0002] Due to the complexity and diversity of the soil environment, some hard and large stones or metal objects are often hidden in the soil. When a bulldozer is doing bulldozing operations, the bulldozer shovel often collides with these hard objects. Since the rear side of the bulldozer shovel is generally pushed to move by the mounting arm, and the mounting arm only contacts a part of the bulldozer shovel, when the front surface of the bulldozer shovel pushes hard objects on both sides, the rear side has no support, which easily causes the front plate of the bulldozer shovel to be damaged, thereby affecting the bulldozing effect. In severe cases, the bulldozer shovel needs to be directly replaced, causing the bulldozer shovel to be scrapped. Therefore, those skilled in the art provide a bulldozer shovel and its protective structure to solve the problems raised in the above background technology. Summary of the invention

[0003] The object of the present invention is to provide a bulldozer blade and a protective structure thereof to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0014] See also Figures 1 to 3In an embodiment of the present invention, a bulldozer and its protective structure include a bulldozer. The bulldozer is of split design and includes a first bulldozer 1 and a second bulldozer 2. The first bulldozer 1 and the second bulldozer 2 are arranged in parallel. The front side surfaces of the first bulldozer 1 and the second bulldozer 2 are fixedly connected to a bulldozer front plate 3. The middle parts of the rear surfaces of the first bulldozer 1 and the second bulldozer 2 are fixedly connected to a reinforcing block 9. An adjusting arm 6 is hingedly connected inside the reinforcing block 9. Deflection mechanisms are arranged on both sides of the adjusting arm 6.

[0015] Preferably, the deflection mechanism includes a second hydraulic cylinder 12 , a fixed portion of the second hydraulic cylinder 12 is hinged to a side surface of the adjusting arm 6 , and a driving portion end of the second hydraulic cylinder 12 is hinged to a rear surface of the first dozer 1 or the second dozer 2 .

[0016] Preferably, the hinges between the second hydraulic cylinder 12 and the first dozer 1 or the second dozer 2 are located on both sides of the reinforcing block 9, so that a triangular frame structure is formed between the second hydraulic cylinder 12, the adjusting arm 6 and the dozer, which has high stability and facilitates the movement of the dozer to push the material away.

[0017] Preferably, a pressure sensor 13 is installed on the surface of the fixed part of the second hydraulic cylinder 12, and the detection end of the pressure sensor 13 extends to the inside of the second hydraulic cylinder 12, so as to detect the pressure borne by the second hydraulic cylinder 12. When a large stone is pushed somewhere on the front shovel front plate 3 of the front side of the first dozer 1 or the second dozer 2, and the shovel front plate 3 is squeezed, the pressure of the second hydraulic cylinders 12 on both sides of the rear of the first dozer 1 or the second dozer 2 will deviate. When one of the second hydraulic cylinders 12 exceeds the critical value, the pressure sensor 13 will detect the pressure borne by the second hydraulic cylinder 12. At this time, the second hydraulic cylinder 12 will retract and the second hydraulic cylinder 12 on the other side will extend, as shown in the shovel front plate 3. At this time, since the first dozer 1 or the second dozer 2 is inclined, the force borne by it from the large stone can be unloaded, thereby protecting the first dozer 1 or the second dozer 2.

[0018] Preferably, it also includes a main beam 4, which is located at the rear side of the first dozer 1 and the second dozer 2. An extension block 10 is fixedly connected to the surface of the main beam 4 facing the first dozer 1 and the second dozer 2. A rotating shaft 11 is fixedly connected to the interior of the extension block 10. The ends of the two adjustment arms 6 away from the first dozer 1 or the second dozer 2 are hinged to the surface of the extension block 10.

[0019] Preferably, two columns 7 are vertically fixed to the upper surface of the main beam 4, and the two columns 7 are respectively located directly behind the two adjusting arms 6. The front surfaces of the two columns 7 are hinged with first hydraulic cylinders 8, and the ends of the driving parts of the two first hydraulic cylinders 8 are respectively hinged to the upper surfaces of the adjusting arms 6. The front ends of the adjusting arms 6 can be controlled to be lifted or lowered by telescoping the first hydraulic cylinders 8, thereby adjusting the position of the shovel front plate 3.

[0020] Preferably, a mounting frame 5 is fixedly connected to the rear surface of the main beam 4 .

[0021] The working principle of the present invention is as follows: by setting a first dozer 1 and a second dozer 2, the dozers are separated, and adjusting arms 6 for horizontal adjustment are respectively installed at the rear thereof, second hydraulic cylinders 12 are arranged on both sides of the adjusting arms 6, and the internal pressure of the second hydraulic cylinders 12 is detected by a pressure sensor 13, so that when a large stone is pushed somewhere on the front plate 3 of the front side of the first dozer 1 or the second dozer 2, when the front plate 3 is squeezed, the pressure of the second hydraulic cylinders 12 on both sides of the rear of the first dozer 1 or the second dozer 2 will deviate, and when one of the second hydraulic cylinders 12 exceeds a critical value, the pressure sensor 13 will detect the internal pressure of the second hydraulic cylinders 12. 13 will detect the pressure on the second hydraulic cylinder 12, control the second hydraulic cylinder 12 to retract, and the other second hydraulic cylinder 12 hinged with it on the surface of the same adjusting arm 6 will extend, so that the first dozer 1 or the second dozer 2 is in an inclined state, as shown in the front plate 3 of the shovel, and the force from the large stone is relieved, so as to protect the first dozer 1 or the second dozer 2. When the large stone is located in the middle of the front side of the first dozer 1 or the second dozer 2, since the reinforcement block is provided on the rear side, the thickening treatment at this place can enhance the force condition at this place, and can protect it and prevent deformation.

[0022] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
