[0002] Excavator arm rod is the important component of excavator, mainly including swing arm and bucket rod, they are also called big arm and small arm.The working principle of excavator arm rod is based on the principle of link mechanism, the movement of each part is realized by the extension of oil cylinder.The lower hinge point of swing arm is hinged with the connecting lug on rotary table, and the lifting of swing arm is realized by the support and stroke change of swing arm oil cylinder.The bucket rod is hinged with the upper end of swing arm, and the swing of bucket rod is realized by the stroke change of bucket rod oil cylinder.In the process of excavation, by adjusting the angle of swing arm and bucket rod and the stroke of oil cylinder, the excavation, loading, lifting and rotation of bucket can be realized.
[0003] At present, in the operation process of excavator arm rod, in order to improve work efficiency and flexibility, multifunctional conversion head is generally used to realize the quick conversion between drilling equipment and bucket. However, this design has a significant disadvantage in practical application, that is, the driving mode required by drilling equipment and bucket is different, which leads to relatively complicated conversion process.
[0004] Specifically, drilling equipment usually needs high rotation speed and torque to complete rock or soil drilling operation, while bucket pays more attention to the efficiency of excavation and loading. Because the requirements of the two operation modes for driving force are completely different, when excavator changes operation tool, it often needs to adjust or reconfigure arm rod or conversion head to adapt to different driving requirements.
[0005] This conversion process not only increases the workload of operators, but also may affect the operation efficiency. In addition, frequent conversion may cause certain wear and damage to excavator arm rod and conversion head, thereby increasing maintenance cost and downtime. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the following will further describe the utility model in combination with specific embodiments.
[0027] In the field of modern engineering machinery, excavators, as a kind of multifunctional heavy equipment, their continuous innovation in design and function is an important driving force for the progress of the industry. This paper will discuss an innovative drilling device on the arm of an excavator. This device not only improves the work efficiency of the excavator, but also greatly enhances its versatility and flexibility.
[0028] As shown in Figure 1 - Figure 5 The drilling device mainly consists of three core parts: arm system, extension device and excavator bucket 5. Specifically, the first arm 1 serves as the foundation of the entire device, stably supporting the subsequent components. The first extension device 2 installed on it is controlled by a precise hydraulic or electric system, realizing the extension function of the first arm 1, thereby adjusting the operation range.
[0029] Next, the second arm 3 is ingeniously connected to the end of the first arm 1, and its design fully considers mechanical balance and stability. The second arm 3 is also equipped with a second telescopic device 4, further refining the operation accuracy and depth. The excavator bucket 5, as the execution component, is installed at the end of the second arm 3 and can easily handle various excavation tasks through precise control of the second telescopic device 4.
[0030] However, the highlight of this device is its unique drilling assembly 12 design. At the inner end face of the second arm 3, a carefully designed mounting bracket 6 is installed, which not only has a strong structure, but also has a reasonable layout, providing a solid foundation for subsequent drilling operations. Inside the mounting bracket 6, the combination of the slide rail 7 and the slide table 8 is like a precise guide rail system, ensuring that the mounting table 9 can move smoothly along the established track. This design not only improves the operation accuracy, but also greatly enhances the stability of the device.
[0031] The mounting table 9, as the support platform of the drilling assembly 12, has its side wall connected to the connecting disc 13 and the docking disc 14, which realizes the flexible rotation of the rotating table 10. The connecting bracket 11 installed on the rotating table 10 stably carries the core component of the drilling assembly 12. The driving equipment of the drilling assembly 12 is ingeniously hidden inside the connecting bracket 11 and is firmly fixed by bolts and other fasteners, ensuring safety and stability during operation.
[0032] Multiple docking hole positions 15 are opened on the connecting disc 13 and the docking disc 14. These hole positions are distributed in a ring shape and designed concentrically, not only beautiful and elegant, but also realizing fine adjustment of the rotation angle of the drilling assembly 12. By changing the relative position of the docking hole positions 15 on the connecting disc 13 and the docking disc 14, the operator can easily adjust the rotation angle of the drilling assembly 12 to adapt to different operation requirements. In addition, the rubber anti-skid pad set at the connection between the docking disc 14 and the connecting disc 13 effectively prevents sliding and wear during operation, further improving the durability of the device.
[0033] The round hole on the mounting bracket 6 is designed ingeniously and is firmly fixed on the second arm 3 by bolts and other fasteners; the slide rail 7 and the mounting bracket 6, and the mounting table 9 and the slide table 8 are connected by bolts, ensuring the close cooperation and stable connection between the components. At the same time, the equidistant design of multiple docking hole positions 15 not only looks beautiful and elegant, but also facilitates quick and accurate adjustment by the operator;
[0034] The operator needs to check all parts of the drilling device on the excavator arm, including the arm system, telescopic device, and bucket 5, etc. After confirming that everything is in good condition, start the excavator and prepare it for work. Ensure that the first arm 1 is securely fixed to the excavator and check the connection for tightness. After starting the excavator, adjust the position and angle of the first arm 1 through the control system of the excavator itself to prepare for subsequent work. Through the control panel or remote control of the excavator, operate the first telescopic device 2 and the second telescopic device 4. First, control the first telescopic device 2 to make the first arm 1 extend forward or backward to the appropriate position. Then, adjust the second telescopic device 4 to control the extension of the second arm 3 and further refine the work range.
[0035] After confirming that the second arm 3 has been adjusted to the appropriate position, the operator needs to install the drilling assembly 12. First, fix the mounting bracket 6 to the inner end face of the second arm 3 and ensure stability through bolts and other fasteners. Then, install the slide rail 7 and the slide table 8 to ensure smooth sliding. Next, place the mounting table 9 on the slide table 8 and fix the rotating table 10 to the mounting table 9 through the connection of the connecting disc 13 and the counter disc 14. Finally, install the drilling assembly 12 on the connecting bracket 11 of the rotating table 10 and fix it through bolts and other fasteners. According to the angle of drilling required, the operator can adjust the rotation angle of the drilling assembly 12 by changing the relative position of the counter hole positions 15 on the connecting disc 13 and the counter disc 14. During the adjustment process, pay attention to ensure that the counter hole positions 15 are tightly connected to prevent sliding and wear during operation.
[0036] After everything is ready, the operator can start the driving equipment of the drilling assembly 12 and begin the drilling operation. Through the control panel or remote control of the excavator, control the rotation speed and feed speed of the drilling assembly 12 and make accurate adjustments according to the work requirements. At the same time, pay attention to the situation during drilling and adjust the operation parameters in time to ensure the quality of the work. After the drilling operation is completed, turn off the driving equipment of the drilling assembly 12 and stop the excavator. The operator needs to clean the drilling device of mud, stones and other debris and check whether there is wear or damage to the parts. If necessary, replace or repair the relevant parts in time to ensure that the equipment can continue to work normally.
