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.

[0026] See also Figure 1-2 A new type of energy-saving excavator comprises an excavator body 1, a boom 10 is arranged on the upper outer surface of the excavator body 1, a fixing group 9 is fixedly connected to the upper outer surface of the boom 10, a hydraulic cylinder 11 is fixedly connected to the front outer surface of the fixing group 9, a movable clamp is fixedly connected to the telescopic end of the hydraulic cylinder 11, a bucket cylinder 12 is fixedly connected to the rear outer surface of the movable clamp, and the bucket cylinder 12 is located directly below the hydraulic cylinder 11, an oil tank is fixedly connected to the upper inner surface of the excavator body 1, a rectangular box is arranged on the front outer surface of the oil tank, a liquid oil pipe 8 is arranged on the upper outer surface of the boom 10, and a lower portion of the rectangular box is fixedly connected to the upper inner surface of the excavator body 1. The inner surface of the end is fixedly connected with a driving motor 3, the left outer surface of the driving motor 3 is provided with a hydraulic buffer tank 5, the rear end outer surface of the hydraulic buffer tank 5 is provided with an air compressor 2, the hydraulic buffer tank 5 and the air compressor 2 are connected through a pipeline, the front end outer surface of the boom 10 is movably connected with a bucket piece, the front end outer surface of the bucket piece is provided with a bucket hydraulic cylinder 13, the left outer surface of the boom 10 is provided with a boom hydraulic cylinder 6, the boom hydraulic cylinder 6 and the bucket hydraulic cylinder 13 are both double-cylinder structures, which further improves the energy-saving effect of the new energy-saving excavator, and the hydraulic buffer tank 5 and the air compressor 2 are both horizontally installed;

[0027] On the basis of the boom 10, the new energy-saving excavator has added a special hydraulic cylinder system. The special hydraulic cylinder system generates compressed gas through the air compressor 2 and outputs it to the hydraulic buffer tank 5. The hydraulic buffer tank 5 stores the compressed gas and supplies gas to the hydraulic cylinder 11 through the gas pipeline 4 when needed. The hydraulic cylinder 11 receives the pressure energy of the gas and converts it into the reciprocating motion of the piston. The special hydraulic cylinder system uses the compressed gas generated by the air compressor 2, and through the storage and release of the hydraulic buffer tank 5, the pressure energy of the gas is efficiently converted into the piston motion of the hydraulic cylinder 11. Compared with the traditional hydraulic system, this energy conversion method has smaller losses and higher efficiency. The use of the special hydraulic cylinder system and the boom cylinder 12 can achieve more coordinated and efficient excavation actions. This coordination method can better adapt to different excavation needs and reduce unnecessary energy consumption and waste. In summary, the new energy-saving excavator achieves more energy-saving, efficient and environmentally friendly effects by adding a special hydraulic cylinder system on the original basis. This not only reduces the cost of use, but also is conducive to promoting the progress and development of the industry.

[0028] The special hydraulic cylinder system utilizes the compressed gas generated by the air compressor 2, which is stored and released through the hydraulic buffer tank 5. After the gas enters the hydraulic buffer tank 5, the hydraulic buffer tank 5 releases oil into the oil pipe, which can be efficiently converted into the piston movement of the hydraulic cylinder 11. The air compressor 2 is only started when in use and is idle at other times. When in use, the hydraulic cylinder 11 performs support and buffering. The hydraulic cylinder 11 is connected to the large-capacity hydraulic buffer tank 5 and can provide high-pressure buffering energy.

[0029] The output end of the air compressor 2 is fixedly connected to a gas pipeline 4, and one end of the gas pipeline 4 is connected to the input end of the hydraulic cylinder 11 for easy connection. The input end of the boom cylinder 12 is fixedly connected to the gas pipeline 4, and a box cover 7 is hinged on the upper outer surface of the rectangular box. The gas pipeline 4 extends from the output end of the air compressor 2 and serves as a gas transmission channel to transport the compressed gas to other components. This fixed connection method ensures stable gas transmission and avoids leakage problems. One end of the gas pipeline 4 is connected to the input end of the hydraulic cylinder 11. This connection method allows compressed gas to directly enter the hydraulic cylinder 11. The hydraulic cylinder 11 uses the pressure energy of the gas to drive the piston to move, thereby realizing mechanical operation. This connection method simplifies the system structure and improves work efficiency.

[0030] A first rectangular mounting groove matched with the rectangular box is provided on the upper outer surface of the excavator body 1. The excavator body 1 is fixedly connected to the rectangular box through the first rectangular mounting groove. The rectangular box can be stably mounted on the excavator body 1, ensuring the stability and reliability of the overall structure. A rectangular baffle is fixedly connected to the right outer surface of the box cover 7. An arc handle is fixedly connected to the upper outer surface of the rectangular baffle, which enhances the stability of the box cover 7 and also provides an additional support or gripping point for the operator. A plurality of first semicircular clips are fixedly connected to the excavator body 1, and the first semicircular clips are used to fix the liquid oil pipe 8. A plurality of second semicircular clips are also fixedly connected to the excavator body 1, and the second semicircular clips are used to fix the gas pipeline 4, ensuring that the oil pipe will not move or loosen during work. A plurality of second semicircular clips are also fixedly connected to the excavator body 1, and the second semicircular clips are used to fix the gas pipeline 4. The second semicircular clips are designed to fix the gas pipeline 4, ensuring the stability and sealing of the gas pipeline 4.

[0031] In summary, these design details take into account the various needs of the excavator in the actual working process, which not only enhances its structural stability, but also provides the operator with a better operating experience. This meticulous design and consideration makes the excavator more reliable, efficient and user-friendly.
