It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0036] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] Refer to Figures 1-9, An excavator with ecological protection function, including a support platform 1. On one side of one end of the top of the support platform 1, a cab 2 is fixed. On one side of the cab 2, a double-layer protective glass 3 is fixed. The double-layer protective glass 3 is double-layer laminated glass, so that the closure of the cab 2 through the double-layer protective glass 3 can increase the sound insulation effect inside the cab 2. On the top of the support platform 1 and on one side of the cab 2, a support guard plate 4 is fixed. On the top of the support platform 1 and inside the support guard plate 4, an engine 6 is fixed, so that the engine 6 is located on one side of the cab 2. Furthermore, the distance between the engine 6 and the cab 2 can be increased compared with the distance when the engine 6 is placed behind the cab 2. Moreover, the sound transmitted into the cab 2 by the engine 6 can be better consumed to reduce noise;

[0038] In this embodiment, the cab 2 and the engine 6 on the top of the support platform 1 are arranged in parallel and in line, which increases the distance between the cab 2 and the engine 6 and keeps away from the noise and resonance generated by the engine 6;

[0039] In this embodiment, the distance between the cab 2 and the engine 6 assembled on the support platform 1 is greater than 383 mm.

[0040] On the side of the support guard plate 4 close to the cab 2, a support iron plate is fixed. Inside the support iron plate, a noise reduction component 8 is fixed, so that the noise emitted by the engine 6 can be offset again through the noise reduction component 8. On the top of the support platform 1 and between the noise reduction component 8 and the cab 2, an air filter 10 is fixed, and then the air entering the engine 6 is filtered through the air filter 10;

[0041] The noise reduction component 8 includes a vibration damping plate 17, a sound insulation plate 18, a sound absorption cotton 19 and a sound insulation cotton 20. The sound absorption cotton 19 is fixed on the side of the sound insulation cotton 20 close to the engine 6. The vibration damping plate 17 is fixed on the side of the sound insulation cotton 20 close to the cab 2. The sound insulation plate 18 is fixed on the side of the vibration damping plate 17 close to the cab 2, so that the noise when the engine 6 works can be offset in turn in the order of the sound absorption cotton 19, the sound insulation cotton 20, the vibration damping plate 17 and the sound insulation plate 18. Furthermore, the noise when the engine 6 works can be reduced through the noise reduction component 8, and combined with the noise reduction of the double-layer protective glass 3, the harm to the eardrums of the driver inside the cab 2 caused by noise can be reduced through multiple noise reduction methods;

[0042] Inside the support guard plate 4 and at one end of the engine 6, a radiator 7 is fixed, so that the engine 6 can be cooled during operation through the radiator 7. The air inlet of the radiator 7 is located at the end far from the engine 6, and the air outlet of the radiator 7 is located at the other end. Thus, the radiator 7 can directly cool the engine 6 by passing the air in front of the excavator during driving through the air inlet and the air outlet. At the same time, through the operation of the radiator 7, the external heat dissipation effect of the engine 6 during operation is better, and the noise generated by the engine 6 during operation is reduced again through the flow of air;

[0043] At the other end of the top of the support platform 1, a counterweight 5 is fixed. Then, the counterweight of the support platform 1 is increased through the counterweight 5, and then the support platform 1 is more balanced. Thus, the counterweight 5 is placed on the top of the support platform 1 and at the end of the engine 6 far from the radiator 7. One side of the counterweight 5 is rotatably connected to a first side tail plate 14, and the other side of the counterweight 5 is rotatably connected to a second side tail plate 16. An exhaust passage 9 is provided inside the first side tail plate 14, so that the air for cooling the engine 6 by the radiator 7 can be discharged through the first side tail plate 14, and the air resistance can be reduced and fuel can be saved during driving;

[0044] One side of the first side tail plate 14 far from the counterweight 5 is bolted to the support guard plate 4, and one side of the second side tail plate 16 far from the counterweight 5 is bolted to the counterweight 5. Then, when not under maintenance, the first side tail plate 14 and the second side tail plate 16 are fixed to the counterweight 5 by bolts. Inside the support guard plate 4 on the side far from the cab 2, a first side plate 13 is rotatably connected. One end of the first side plate 13 is bolted to the support guard plate 4. Inside the top of the support guard plate 4, a top plate is rotatably connected, and the side of the top plate that is not rotatably connected to the support guard plate 4 is fixed by bolts. Thus, the first side plate 13 can also be fixed by bolts when not under maintenance; At the top of one end of the counterweight 5 far from the cab 2, a rear tail plate 15 is rotatably connected, and the bottom of the rear tail plate 15 is bolted to the counterweight 5, so that the rear tail plate 15 can be opened or closed by turning the bolts;

[0045] On both sides of one end of the counterweight 5 far from the cab 2, a first flashing light 11 is fixed. On both sides of one end of the counterweight 5 far from the cab 2 and at the bottom of the first flashing light 11, a brake turn signal light 12 is fixed. Thus, through the flashing of the first flashing light 11 and the brake turn signal light 12 during operation, nearby personnel can be more clearly reminded, and the safety during operation is increased. At the same time, the lights of the first flashing light 11 and the brake turn signal light 12 can be selected according to needs.

[0046] Inside the cab 2, a seat 21 is provided, so that the operator can sit on the seat 21 to operate the excavator.

[0047] In other embodiments, the seat 21 can also be improved by pneumatic suspension. During long-term construction, the pneumatic suspension can provide better shock absorption protection for the operator on the seat 21, thus better protecting the waist and shoulders. When working on bumpy roads, it can protect the operator's waist. At the same time, the height of the seat 21 can be adjusted by the pneumatic suspension, enabling operators of different heights to comfortably control the excavator. In addition, the seat 21 can be equipped with ventilation and heating functions to provide better comfort for the operator when working on the seat 21.

[0048] The usage process of an excavator with an ecological protection function provided by the present utility model is as follows: When the excavator is in use, the engine 6 is in a working state. Due to the increased distance between the engine 6 and the cab 2, more noise is dissipated during transmission. The noise generated when the engine 6 operates is partially eliminated by the air intake and exhaust of the air-cooled heat dissipation of the radiator 7. Then, the noise is further reduced by the noise reduction component 8, and then again by the fixation of the double-layer protective glass 3 to the cab 2. Through multiple noise reduction methods, the noise entering the interior of the cab 2 is reduced, thereby enhancing the safety of the operator inside the cab 2.

[0049] When the excavator is moving, the wind from the direction of the excavator's movement can pass through the cooperation of the air intake and exhaust ports of the radiator 7 to more efficiently dissipate heat from the outside of the engine 6. At the same time, the gas flow takes away part of the noise generated when the engine 6 operates. Combining the heat dissipation of the radiator 7 for the engine 6, the excavator can travel a longer distance, and the air for external heat dissipation of the engine 6 is discharged through the exhaust duct 9.

[0050] When the excavator needs to be repaired and maintained, the first side plate 13, the first side tail plate 14, the rear tail plate 15, the second side tail plate 16, and the top plate are all opened by rotating and removing the corresponding bolts, facilitating maintenance without disassembling any working instruments.

The preferred embodiments do not describe all details in detail, nor do they limit the present utility model to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification. These embodiments are selected and specifically described to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can better understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
