[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a protective structure of an excavator fuel tank, comprising a base 1, a disassembly assembly 13 is arranged inside the base 1, a box body 2 is arranged on the upper part of the base 1, mounting plates 6 are fixedly connected to the outside of the box body 2 on both sides, a damper 7 is fixedly connected to the middle of the mounting plate 6, a protective plate 8 is fixedly connected to the output end of the damper 7, one end of a buffer rod 9 is rotatably connected to the outside of the protective plate 8, U-shaped rods 11 are fixedly connected to the outside of the mounting plate 6 on both sides, buffer blocks 10 are slidably connected to the outside of the two U-shaped rods 11, the other ends of multiple buffer rods 9 are rotatably connected to the outside of multiple buffer blocks 10, and buffer springs 12 are sleeved in the middle of the two U-shaped rods 11, a filling port 3 is fixedly connected to the left side of the outside of the box body 2, a sealing cover 4 is arranged inside the filling port 3, bumps 5 are fixedly connected to the outside of the base 1 on all sides, and mounting holes are opened inside the multiple bumps 5.

[0025] During the excavation operation, when the gravel hits the protective plate 8, a huge impact force will be generated. The protective plate 8 first bears the impact of the gravel. When hit, the protective plate 8 not only bears a huge impact force, but also quickly transmits this force. At this time, the damper 7 plays a key role. The damper 7 has excellent shock absorption ability. It can shrink quickly when it is impacted by external force, thereby reducing the impact on the protective plate 8. As the damper 7 shrinks, the protective plate 8 also moves. This movement process does not exist in isolation, but is closely connected to the buffer rod 9 that is connected to the outside and rotates around. When the protective plate 8 moves, the buffer rod 9 will also move with it. This design not only enhances the stability of the protective plate 8, but also improves the shock absorption effect of the entire protection system. When the four buffer rods 9 move, they will move on both sides of the outside of the two U-shaped rods 11 with the four buffer blocks 10 that are connected to the other end. These four buffer blocks 10 are like four flexible arms, ready to deal with the impact of gravel at any time. When the buffer blocks 10 move, they will squeeze the buffer springs 12 set in the middle of the two U-shaped rods 11. As the core component of the entire protection system, the buffer spring 12 has excellent elasticity and shock absorption capabilities. When squeezed by the buffer block 10, the buffer spring 12 will deform, thereby absorbing the force generated by the impact of the gravel. This deformation process not only effectively disperses the impact force. The protective plate 8 can effectively block the impact of the gravel, while the damper 7, buffer rod 9, buffer block 10 and buffer spring 12 work together to convert the impact force into elastic potential energy and disperse it. During excavation operations, the protective plate 8 can absorb the force generated by the splashing of gravel, avoiding direct impact on the surface of the fuel tank, causing dents, scratches or even perforations on the wall of the fuel tank, and improving the service life of the fuel tank.

[0026] Reference Figure 4The disassembly assembly 13 includes a motor 1302, which is fixedly connected to the outside of the base 1. The output end of the motor 1302 is fixedly connected to a rotating rod 1301. The rear side of the rotating rod 1301 is fixedly connected to a first bevel gear 1303. The lower part of the first bevel gear 1303 is meshed with a second bevel gear 1304. The second bevel gear 1304 is fixedly connected to a transmission rod 1305. The transmission rod 1305 is rotatably connected to the inside of the base 1. The transmission rod 1305 is fixedly connected to a spur gear 1306 on the outside. The spur gear 1306 is meshed with rack plates 1307 on both sides of the outside. The two rack plates 1307 are fixed on the outside. A guide ring 1308 is fixedly connected, the upper parts of the two rack plates 1307 are fixedly connected with mounting rods 1309, the upper parts of the two mounting rods 1309 are fixedly connected with positioning plates 1310, the inner walls of the two positioning plates 1310 are provided with protective pads 16, the inside of the base 1 is fixedly connected with guide rods 14 on both sides, the two guide rings 1308 are slidably connected to the outside of the two guide rods 14, through holes 15 are opened on both sides of the upper part of the base 1, the two mounting rods 1309 are slidably connected to the inside of the two through holes 15, the upper parts of the two positioning plates 1310 are fixedly connected with connecting rods 17, and the tops of multiple connecting rods 17 are fixedly connected with reinforcing plates 18.

[0027] When the oil tank needs to be disassembled, the motor 1302 is started. The rotation of the motor 1302 will drive the rotating rod 1301 connected thereto to rotate synchronously. The other end of the rotating rod 1301 is fixedly connected to the first bevel gear 1303, so its rotation will also drive the first bevel gear 1303 to rotate. Next, the rotation of the first bevel gear 1303 will drive the second bevel gear 1304 connected to it at the lower part to rotate through the meshing action between the gears. The design of this bevel gear allows the rotation to be smoothly transmitted from one axis to another and changes the direction of rotation. As the second bevel gear 1304 rotates, the transmission rod 1305 also starts to rotate. The transmission rod 1305 is fixedly connected to the spur gear 1306 inside, so its rotation will also drive the spur gear 1306 to rotate. The rotation of the spur gear 1306 is a key step in the entire mechanical structure because it drives the movement of the rack plate 1307 through the meshing action. The movement of the rack plate 1307 is the last step in the oil tank disassembly process. Since both sides of the rack plate 1307 are meshed with the spur gear 1306, its moving direction is controlled by the spur gear 1306. When the rack plate 1307 moves, it will drive the two mounting rods 1309 fixedly connected at the upper part to move away from each other. The two mounting rods 1309 were originally tightly fitted together to fix the oil tank. In the process of the two mounting rods 1309 moving away from each other, the two positioning plates 1310 fixedly connected at their upper parts will also move away from each other. The two positioning plates 1310 were originally used to limit the position of the oil tank to prevent it from shaking during operation. However, as the mounting rods 1309 move away, the limiting effect of the positioning plates 1310 on the oil tank is also released. At this time, the operator can easily remove the oil tank from the fixed position and perform subsequent maintenance operations. When installing the oil tank, it is only necessary to repeat the above operation process so that the two positioning plates 1310 can fix the oil tank again, which makes it easy to install and disassemble the oil tank, and the operation is simple and convenient, saving time and effort.

[0028] Working principle: During excavation, the flying gravel will first hit the protective plate 8. When the protective plate 8 is hit, the force is transmitted and contracted through the damper 7, which brings the protective plate 8 to contract. The protective plate 8 moves and brings the buffer rods 9 connected to the outside and rotating around to move. When the four buffer rods 9 move, the four buffer blocks 10 connected to the other end and rotating at the other end move on both sides of the outside of the two U-shaped rods 11. The four buffer blocks 10 move relative to each other to squeeze the buffer springs 12 set in the middle of the two U-shaped rods 11, so that the two buffer springs 12 are deformed under the force. The force generated by the impact of the gravel is absorbed by the deformation of the two buffer springs 12 under the force. During excavation, the protective plate 8 can absorb the force generated by the flying gravel to avoid directly hitting the surface of the fuel tank, which causes dents, scratches or even perforations on the wall of the fuel tank, thereby increasing the service life of the fuel tank. Then, when the fuel tank needs to be disassembled for maintenance, the motor 1302 is started, and the motor 1302 rotates and brings the rotating rod 1 When the gear 301 is rotated, the rotating rod 1301 rotates and drives the first bevel gear 1303 fixedly connected to the rear side of the outside to rotate. The first bevel gear 1303 rotates and drives the second bevel gear 1304 meshingly connected at the bottom to rotate. The second bevel gear 1304 rotates and drives the transmission rod 1305 fixedly connected to the inside to rotate. The transmission rod 1305 rotates and drives the spur gear 1306 fixedly connected to the outside to rotate. The spur gear 1306 rotates and drives the rack plate 1307 meshingly connected on both sides of the outside to move. The rack plate 1307 moves and drives the two mounting rods 1309 fixedly connected to the upper part to move away from each other. When the two mounting rods 1309 move away from each other, the two positioning plates 1310 fixedly connected to the upper part move away from each other, so that the two positioning plates 1310 release the limit on the box body 2. Then the operator can easily remove the oil tank. During installation, the above operation is repeated so that the two positioning plates 1310 fix the box body 2, thereby facilitating the installation and disassembly of the oil tank, and the operation is simple and convenient, saving time and effort.
