[0047] Embodiment 3

[0048] Reference Figure 2 and Figure 3 , the third embodiment of the utility model further provides a digger. It also includes a bucket arm 201 rotatably connected with the bucket 101, a bucket hydraulic cylinder 202 rotatably connected with the bucket 101, a movable arm 203 rotatably connected with the bucket arm 201, a sensor 204 arranged on the outer wall of the bucket arm 201, a sensor 204 arranged on the outer wall of the bucket hydraulic cylinder 202, and a sensor 204 arranged on the outer wall of the movable arm 203.

[0049] Among them, the model of the digger is 336D excavator, the control room is equipped with an intelligent control panel, the bucket arm 201, the bucket hydraulic cylinder 202 and the movable arm 203 are common structures, and the sensor 204 is an inclination sensor for collecting the acceleration, angular velocity, angle and environmental magnetic field information of the component to upload as a reference for the operator to operate accurately. It should be noted that the collected angle refers to the angle between the measured component and the ground and the vertical plane and other components equipped with the sensor 204.

[0050] Further, the sensor 204 is fixedly connected with the mounting sheet 204a on one side of the dipper boom 201, the bucket hydraulic cylinder 202 and the swing arm 203, the mounting sheet 204a is fixedly connected with the dipper boom 201, the mounting sheet 204a is fixedly connected with the bucket hydraulic cylinder 202, and the mounting sheet 204a is fixedly connected with the swing arm 203.

[0051] The selected model of the sensor 204 is HWT901B, and the HWT901B sensor 204 can collect attitude information of each part as an inclination sensor, collect acceleration, angular velocity, angle and environmental magnetic field data, and upload to an intelligent platform, so that the operator in the excavator can see on the intelligent control panel, and the on-site dispatching and remote management are facilitated. It should be noted that the sensor 204 has an aluminum shell, so the sensor 204 does not directly contact the outside world, and a lightweight, corrosion-resistant and excellent electromagnetic shielding aluminum shell is specially selected to encapsulate the sensor 204. Specifically, a high-strength, lightweight and corrosion-resistant aviation-grade aluminum alloy is selected as the shell material. This aluminum alloy not only has excellent mechanical properties and can withstand the vibration and impact during the operation of the excavator, but also has corrosion resistance that can effectively resist the corrosion of corrosive substances such as acid, alkali and salt that may exist in complex geological environments. The shell is integrally formed by die casting process to ensure compact structure and no gaps, thereby improving the overall sealing performance and protection level. The surface of the shell is treated by anodic oxidation to further enhance its corrosion resistance and wear resistance. In the design of the aluminum shell, special attention is paid to the optimization of electromagnetic shielding performance. By using advanced technologies such as multiple metal shielding layers and conductive coatings, the influence of external electromagnetic interference sources on the internal electronic elements of the sensor 204 is effectively isolated, ensuring the accuracy and stability of the sensor data. The mounting sheet 204a serves as a connecting structure between the sensor 204 and the dipper boom 201, the bucket hydraulic cylinder 202 and the swing arm 203, so that the sensor 204 is not directly connected with the components. It should be noted that the mounting sheet 204a can be connected with the dipper boom 201, the bucket hydraulic cylinder 202 and the swing arm 203 in various ways, such as welding and bolt fixing. The shape of the mounting sheet 204a can be circular, square, etc. In this embodiment, a square mounting sheet 204a is selected.

[0052] Further, the second bolt 204b is provided through the outer wall of the mounting sheet 204a, the second bolt 204b fixes the mounting sheet 204a with the dipper boom 201, the second bolt 204b fixes the mounting sheet 204a with the bucket hydraulic cylinder 202, and the second bolt 204b fixes the mounting sheet 204a with the swing arm 203.

[0053] The stick 201 is provided with screw holes for the second bolt 204b to be fixedly connected to the bucket hydraulic cylinder 202 and the boom 203. A second bolt 204b is provided through each of the four corners of the square mounting plate 204a.

[0054] In use, the sensor 204 is fixed to the stick 201, the bucket hydraulic cylinder 202, and the outer wall of the boom 203 using the second bolt 204b. After the operator enters the excavator's control room and starts the excavator, the boom 203 rotates, driving the stick 201. The bucket hydraulic cylinder 202 controls the rotation of the bucket 101. The intelligent control panel is activated to view the acceleration, angular velocity, angle, and ambient magnetic field information collected by the sensor 204 on the component it is located in, and uploads it to the intelligent platform to assist the operator in precise operation. When the sensor 204 needs to be replaced, the second bolt 204b is loosened to disengage the mounting plate 204a from the stick 201, the bucket hydraulic cylinder 202, and the outer wall of the boom 203, after which a new sensor 204 can be installed.

[0055] In summary, this design uses a process tilt sensor to provide operators with accurate data references, significantly reducing reliance on operator experience and improving operational accuracy. At the same time, the detachable design of the sensor facilitates installation, disassembly, and replacement, improving the flexibility and ease of operation of the equipment.
