Description

[0002] The light-duty wheeled excavator is an excavating machine with tires as walking parts, which is referred to as a wheel excavator. The wheel excavator has a high walking speed, does not damage the road surface, can be self-transferred over a long distance, and can quickly replace various operating devices. The maximum walking speed of the wheel excavator abroad is mostly 25-40 km / h, and the maximum walking speed of the wheel excavator made in China is mostly 20-35 km / h. Although the working efficiency of the wheel excavator is not as good as that of the tracked excavator, compared with the high transfer cost of the tracked excavator, the wheel excavator has more economic advantages when frequently transferred. Due to the distinctive characteristics of being mobile, flexible, and efficient, the wheel excavator is widely used in material excavation and moving in municipal maintenance engineering, highway traffic construction, and rapid repair. When the light-duty wheeled excavator is working, the machine itself will vibrate, which will affect the construction of the workers and bring bad working experience to the workers.

[0003] To this end, a wheel excavator capable of preventing body sway is disclosed in Chinese Utility Model No. CN211690483U. The wheel excavator capable of preventing body sway comprises a vehicle frame, a body capable of rotary motion is arranged on the upper part of the vehicle frame, a supporting device is arranged between the vehicle frame and the body, and the supporting device is uniformly arranged along the circumference of the rotary center of the body.

[0045] Example 3

[0046] Reference Figures 1-6This is the third embodiment of the present invention. Based on the above two embodiments, when using the excavator, the operator drives the excavator from the cab 5. The traveling wheels 2 help move the excavator to the work site. After arriving at the designated location, the motor 13 is turned on. The rotation of the motor 13 drives the worm gear 14 to rotate, which in turn drives the worm wheel 15 to rotate. The rotation of the worm wheel 15 drives the rotating rod 16 to rotate, which in turn drives the bevel gear 17 to rotate. The rotation of the bevel gear 17 drives the bevel gear 18 to rotate, which in turn drives the rotating rod 20 to rotate. The rotation of the rotating rod 20 drives the gear 21 to rotate, which in turn drives the rack 72 to move. The movement of the rack 72 drives the fixed plate 73 to move, which in turn drives the damping rod 7... 4. Spring 76 and washer 75 move. When washer 75 touches the ground, it is fixed. While bevel gear 18 rotates, it drives bevel gear 22 to rotate. Bevel gear 22 rotates, driving rotating rod 23 to rotate. Rotating rod 23 drives gear 24 to rotate. Gear 24 rotates, driving rack 82 to move. Rack 82 moves, driving support leg 83 to move. Support leg 83 helps to fix and support frame 1, making the excavator more stable during operation. During excavation, the operator controls bucket assembly 6 from inside the cab 5, rotating the robotic arm 61. The robotic arm 61 rotates, driving bucket body 62 to move. Bucket body 62 completes the excavation work. During excavation, frame 1 shakes. Fixing plate 73 and damping rod 7... 4. The cooperation of spring 76 and washer 75 helps reduce the vibration generated by the excavator. Washer 75 helps to better contact the ground. When the fixed plate 4 shakes, the fixed plate 4 drives the ball 104 to move. The movement of ball 104 drives the cylindrical block 103 to move. The downward movement of cylindrical block 103 compresses the hydraulic oil in spring 105 and cylindrical groove 102. Spring 105 and the hydraulic oil in cylindrical groove 102 cooperate to absorb some energy and flow to reservoir 107 through connecting pipe 106. The hydraulic oil entering reservoir 107 pushes the pressure plate 109 upward. The movement of pressure plate 109 compresses spring 1011. The elasticity of spring 1011 and the cooperation of hydraulic oil further absorb energy. The cooperation of the components reduces the vibration of the excavator. The shaking of the fixed plate 4 reduces the shaking of the cab 5. Simultaneously, the fixed plate 4 moves the ball 99, which in turn moves the cylindrical block 98. The movement of the cylindrical block 98 moves the fixed frame 97 and the rotating shaft 96. The rotating shaft 96 rotates on the support rod 95, causing the support rod 95 to rotate. The rotation of the support rod 95 causes the rotating shaft 94 to rotate, which in turn moves the fixed frame 93. The movement of the fixed frame 93 causes the slider 92 to move within the groove 91. When the slider 92 moves, the interaction between the slider 92 and the groove 91 compresses the spring 911. The cylindrical rod 910 helps limit the movement of the spring 911. The interaction between the spring 911 and the components...To further reduce the swaying of the fixed plate 4 and provide a comfortable working environment for the operator, this invention, through the cooperation of the buffer outrigger assembly 7, buffer assembly 9, and shock absorber assembly 10, can reduce the excavator's swaying, ensuring normal operation for the operator and providing a better operating experience. The support assembly 8 makes the chassis 1 more stable, the buffer outrigger assembly 7 helps reduce the swaying of the chassis 1, preventing it from shifting and shaking during operation, thus affecting work accuracy. The buffer assembly 9 and shock absorber assembly 10 reduce the swaying of the cab 5, providing a comfortable working environment for the operator and improving work efficiency.
