Usually, the fuel tank is directly exposed on the outside and has no frame support and protection. Therefore, a bulldozer fuel tank assembly with a protective net assembly is needed to solve the existing deficiencies. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1-6As shown in the figure, the utility model provides a technical solution: a bulldozer fuel tank assembly with a protective net assembly, including a base 1 and a box body 2. A set of symmetric bottom plates 3 are movably connected to the top end of the base 1, and frames 4 are fixedly connected to the top ends of the bottom plates 3. An adjusting mechanism 5 is arranged inside the base 1, and the adjusting mechanism 5 is fixedly connected to the bottom end of the frame 4. The box body 2 is movably connected to the opposite sides of the frame 4, and the bottom end of the box body 2 is attached to the top end of the bottom plate 3. A double-layer protection mechanism 6 is arranged outside the frame 4.

[0028] By controlling the bottom plates 3 to approach each other through the adjusting mechanism 5, the frames 4 are made to approach each other, thereby fixing the box body 2 between the frames 4, effectively fixing the position of the fuel tank. And the use of the frame 4 helps to improve the overall firmness of the fuel tank and enhance the safety performance of the fuel tank. The hollow design helps the fuel tank to dissipate heat. In addition, by using the base 1, the fuel tank is connected to the bulldozer. The inner side of the fuel tank faces the bulldozer, and the outer side of the fuel tank is protected by the double-layer protection mechanism 6, which helps to improve the protection effect, reduce the damage caused by gravel impact, and facilitate the replacement of the damaged protective net.

[0029] As Figure 1 and Figure 4 shown in the figure, the adjusting mechanism 5 includes a moving block 501, a fixed block 502, a driving rod 503 and a connecting rod 504. The moving block 501 and the fixed block 502 are both symmetrically arranged. The moving block 501 is located on the opposite side of the fixed block 502. Connecting rods 504 are arranged on both sides of the moving block 501. One end of the connecting rod 504 is movably connected to the side of the moving block 501 through a rotating shaft, and the other end of the connecting rod 504 is movably connected to the inside of the bottom plate 3 through a rotating shaft. A set of symmetric threads are provided on the outer side of the driving rod 503. The driving rod 503 passes through the moving block 501, and the driving rod 503 is threadedly connected to the moving block 501. A chute is provided at the middle position of the base 1. The bottom ends of the moving blocks 501 are both movably connected to the inside of the chute. The bottom ends of the fixed blocks 502 are both fixedly connected to the top end of the base 1. The two ends of the driving rod 503 respectively pass through the fixed blocks 502, and the driving rod 503 is movably connected to the fixed blocks 502 through bearings. The adjusting mechanism 5 further includes an adjusting block 505 and an adjusting rod 506. The adjusting block 505 is fixedly connected to one end of the driving rod 503. The adjusting block 505 passes through the center of the adjusting rod 506, and the adjusting rod 506 is movably connected to the adjusting block 505.

[0030] Rotate the adjusting rod 506 to drive the adjusting block 505 and the driving rod 503 to rotate synchronously. Since the driving rod 503 is threadedly connected to the moving block 501, the moving blocks 501 approach each other along the sliding groove, causing the connecting rod 504 to rotate, thereby pulling the bottom plate 3 closer to each other along the top of the base 1 until the side of the box body 2 moves to the inside of the frame 4. The frame 4 wraps the side of the box body 2 to fix the box body 2 to the top of the base 1, effectively fixing the position of the fuel tank. And the use of the frame 4 helps to improve the overall firmness of the fuel tank and improve the safety performance of the fuel tank. The hollow design helps the fuel tank to dissipate heat.

[0031] As Figure 1 , Figure 5 and Figure 6 shown, the double-layer protection mechanism 6 includes a first protection net 601, a second protection net 602 and a partition 603. Both sides of the first protection net 601 are fixedly connected with a first connecting plate 7, and both sides of the second protection net 602 are fixedly connected with a second connecting plate 8. The second protection net 602 is located outside the first protection net 601. The partitions 603 are symmetrically arranged and are respectively located on the opposite sides of the first connecting plate 7 and the second connecting plate 8. The double-layer protection mechanism 6 further includes fixing columns 604 and limit bolts 605. The fixing columns 604 and the limit bolts 605 are both distributed along the outer side line of the frame 4. The fixing columns 604 are fixedly connected to the outside of the frame 4, and the limit bolts 605 are respectively threadedly connected to the fixing columns 604. The fixing columns 604 sequentially pass through the first connecting plate 7, the partition 603 and the second connecting plate 8, and the fixing columns 604 are movably connected to the first connecting plate 7, the partition 603 and the second connecting plate 8 through which they pass.

[0032] Set the holes on the surface of the first connecting plate 7 on the outside of the fixing columns 604 in sequence to cover the first protection net 601 on the outside of the fuel tank. Then, set the holes on the surface of the partition 603 on the outside of the fixing columns 604 in sequence. Then, set the holes on the surface of the second connecting plate 8 on the outside of the fixing columns 604 in sequence to cover the second protection net 602 on the outside of the first protection net 601. Through the partition 603, a certain interval is maintained between the first protection net 601 and the second protection net 602. Subsequently, thread the limit bolts 605 with the fixing columns 604 one by one to fix the first protection net 601 and the second protection net 602 to the outside of the frame 4. By setting the two-sided protection nets, it helps to improve the protection effect and reduce the damage caused by gravel impact, and it is also convenient to replace the damaged protection nets.

[0033] Working principle: When in use, first, place the bottom end of the box body 2 on the top end of the bottom plate 3. Then, sleeving the center of the adjusting rod 506 on the outside of the adjusting block 505, rotate the adjusting rod 506 to drive the adjusting block 505 and the driving rod 503 to rotate synchronously. Since the driving rod 503 is threadedly connected to the moving block 501, the moving block 501 moves closer to each other along the sliding groove, causing the connecting rod 504 to rotate, thereby pulling the bottom plate 3 to move closer to each other along the top end of the base 1 until the side of the box body 2 moves inside the frame 4, and the frame 4 wraps the side of the box body 2 to fix the box body 2 on the top end of the base 1. Subsequently, sequentially sleeve the holes on the surface of the first connecting plate 7 on the outside of the fixing column 604 to cover the first protective net 601 on the outside of the fuel tank. Then, sequentially sleeve the holes on the surface of the partition plate 603 on the outside of the fixing column 604. Then, sequentially sleeve the holes on the surface of the second connecting plate 8 on the outside of the fixing column 604 to cover the second protective net 602 on the outside of the first protective net 601. Through the partition plate 603, a certain interval is maintained between the first protective net 601 and the second protective net 602. Subsequently, threadedly connect the limit bolts 605 to the fixing column 604 one by one to fix the first protective net 601 and the second protective net 602 on the outside of the frame 4.
