Its design is similar to that of the excavators used in engineering, but it focuses more on entertainment and education work. Therefore, amusement excavators are gradually loved by people;

[0003] Among them, based on the composition of the amusement excavator, the most crucial component is the robotic arm. Since the amusement excavator is an entertainment facility, most of them are electric robotic arms.

By controlling the above pneumatic components, the robotic hand is driven to move in multiple axial directions horizontally or vertically to simulate the multi-dimensional movement of a human arm grasping an object. This implementation method has a high cost, and the pneumatic operation of the compressor and the telescopic cylinder is prone to unstable air pressure, resulting in unstable swinging of the robotic arm.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present utility model: an electric robotic arm of a amusement excavator, including a large arm 9 of the robotic arm, a small arm 13 of the robotic arm, and a substrate 20. A bucket 16 is assembled at the bottom of the small arm 13 of the robotic arm. A fifth movable joint 15 is assembled between the bucket 16 and the small arm 13 of the robotic arm. Three motors 21 are installed at the back end of the substrate 20. An eccentric wheel 1 is installed at the front end of the substrate 20. A connecting rod 2 is connected to the top of the eccentric wheel 1. A main body of the wire 3 is connected above the connecting rod 2. A wire tube 4 is connected to the external position of the main body of the wire 3. The tail end of the wire tube 4 is connected to a platform. A first movable joint 5 is connected between the platform and the large arm 9 of the robotic arm. A first spring 6 is connected to the lower position of the large arm 9 of the robotic arm. A first sliding rod 7 is connected inside the first spring 6. An eighth movable joint 19 is connected between the tail end of the first sliding rod 7 and the platform. A second spring 11 is connected between the large arm 9 and the small arm 13 of the robotic arm.

[0021] A seventh movable joint 18 is assembled at the middle position of the bottom of the small arm 13 of the robotic arm. One end of the second spring 11 is connected to the second spring 11, and the other end of the second spring 11 is connected to the large arm 9 of the robotic arm.

[0022] A third movable joint 10 is assembled at the connection between the large arm 9 of the robotic arm and the second spring 11, and a second movable joint 8 is assembled at the connection between the first sliding rod 7 and the large arm 9 of the robotic arm.

[0023] A third spring 14 is assembled inside the small arm 13 of the robotic arm. A fourth movable joint 12 is assembled at the connection between one end of the third spring 14 and the small arm 13 of the robotic arm, and a sixth movable joint 17 is assembled at the bottom position of the third spring 14.

[0024] An insulating layer is coated on the outer side wall of the substrate 20, and strengthening components 22 are evenly distributed inside the substrate 20.

[0025] The strengthening components 22 include a first diagonal brace 23, a second diagonal brace 24, and a connecting rod 25. The connecting rod 25 is fixed between the second diagonal brace 24 and the connecting rod 25;

[0026] Furthermore, three sets of the eccentric wheels 1 are assembled on the front end face of the substrate 20, and three sets of motors 21 are also assembled on the back end of the substrate 20. Therefore, one motor 21 is adapted to one eccentric wheel 1 to form a transmission operation;

[0027] Furthermore, the connecting rod 25 is fixed between the second diagonal brace 24 and the connecting rod 25. Therefore, the connecting rod 25 enhances the connection stability between the second diagonal brace 24 and the connecting rod 25, thereby improving the strengthening effect;

[0029] Working principle: First, when the motor 21 is started during operation, it can drive the eccentric wheel 1 to rotate. After the eccentric wheel 1 rotates, the rotational motion is changed into a linear motion through the connecting rod 2. Under the linear motion, the wire-pulling main body 3 is pulled to move. After the wire-pulling main body 3 forms a linear motion, it pulls the first sliding rod 7 to perform a linear motion. The force is released through the first spring 6 to complete the coordinated motion of the large arm 9 and the small arm 13 of the robotic arm. During the working process, due to the second spring 11 assembled between the large arm 9 and the small arm 13 of the robotic arm and the third spring 14 assembled inside the small arm 13, it has a certain coordinated effect during operation. Therefore, after the coordinated motion of the large arm 9 and the small arm 13 of the robotic arm, it can cooperate with the bucket 16 to simulate the normal operation of the excavator.
