Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to an excavator boom with self-lubrication function. Background Technology

[0002] In the field of construction machinery, the boom of an excavator is a key actuator, and its performance directly affects the overall operating efficiency and service life of the machine. Traditionally, excavator booms are maintained by manually lubricating the bucket connection points periodically. This method is not only cumbersome but also makes it difficult to ensure timely and even lubrication. Under complex working conditions, insufficient lubrication can easily lead to accelerated joint wear, affecting equipment stability and even causing malfunctions and downtime.

[0003] In existing technologies, traditional excavator boom structures typically lack integrated automatic lubrication designs. Lubrication of critical moving parts such as the bucket often relies on manual periodic oiling, which not only involves high maintenance frequency and inconvenient operation, but also easily leads to accelerated wear due to untimely lubrication, affecting equipment lifespan and operational stability. In addition, under complex working conditions, traditional lubrication methods are difficult to achieve synchronous control with the operation process, resulting in problems of insufficient or excessive lubrication.

[0026] Example

[0027] Reference Figures 1-4 This is an embodiment of the present invention, which provides a digging boom with a self-lubricating function, comprising:

[0028] The fixing mechanism 100 includes a mounting component 101, a base 1011 disposed on the mounting component 101, and a first cylinder 1012 fixedly connected to the outside of the base 1011.

[0029] The drive mechanism 200 includes an adjustment component 201 and a lubrication component 202;

[0030] The adjustment assembly 201 includes a fixed frame 2011, a second cylinder 2012 disposed within the fixed frame 2011, an adjustment frame 2013 connected to the output end of the second cylinder 2012, a third cylinder 2014 disposed within the adjustment frame 2013, and a bucket 2015 connected to the output end of the third cylinder 2014.

[0031] The lubrication assembly 202 includes a lubrication injector 2021 and a filling port 2022 disposed on the top of the lubrication injector 2021.

[0032] Specifically, the lubrication injector 2021 is fixedly installed on one side of the adjusting frame 2013 and is connected to the movable connection part of the bucket 2015 through the oil supply line.

[0033] It should be noted that the lubrication injector 2021 is fixedly installed on one side of the adjusting frame 2013 and is connected to the movable connection part of the bucket 2015 through an oil supply line. This arrangement allows the grease to be directly delivered to the rotating joints or other critical friction parts between the bucket 2015 and the adjusting frame 2013, thereby achieving continuous lubrication during operation, reducing mechanical wear, and extending the service life of the equipment.

[0034] Specifically, the filling port 2022 is located at the top of the lubrication injector 2021 for injecting lubricating oil into the lubrication injector 2021, and is equipped with a sealing cap.

[0035] It should be noted that the filling port 2022 is located at the top of the lubrication injector 2021 and is used to inject lubricating oil into the lubrication injector 2021. It is equipped with a sealing cap. The sealing cap can close the filling port 2022 when not filling, preventing dust and impurities from entering and lubricating grease from leaking, ensuring the cleanliness and reliability of the lubrication system, and facilitating daily maintenance and replenishment operations.

[0036] Specifically, the lubrication injector 2021 is an electric or multi-stage pressure control structure that can automatically deliver lubricating grease to the rotating joints of the bucket 2015 according to a preset cycle or working condition.

[0037] It should be noted that the lubrication injector 2021 is an electric or multi-stage pressure-controlled structure, capable of automatically delivering grease to the rotating joints of the bucket 2015 according to a preset cycle or working condition. This structure allows for setting the lubrication frequency and dosage based on actual working conditions, avoiding manual intervention, improving the automation level of the equipment, and ensuring that key moving parts are always in a good lubricated state, thus reducing the failure rate.

[0038] Specifically, the first cylinder 1012, the second cylinder 2012 and the third cylinder 2014 are electrically connected to the external control system to realize the linkage control of the attitude adjustment and operation of the bucket 2015.

[0039] It should be noted that the first cylinder 1012, the second cylinder 2012, and the third cylinder 2014 are electrically connected to an external control system to achieve coordinated control of the attitude adjustment and operating actions of the bucket 2015. By centrally controlling the sequence and stroke of each cylinder, precise positioning and efficient operation of the bucket 2015 with multiple degrees of freedom can be achieved during excavation operations, improving the overall coordination and operating efficiency of the machine.

[0040] Specifically, the lubrication component 202 is signal-connected to the control system and can synchronously start the lubrication injection program when the bucket 2015 performs continuous operations, realizing the automatic lubrication function.

[0041] It should be noted that the lubrication component 202 is signal-connected to the control system and can synchronously start the lubrication injection program when the bucket 2015 performs continuous operations, realizing the automatic lubrication function. This design realizes the intelligent linkage between the lubrication process and the operation process, without the need for additional downtime for lubrication, while ensuring the operation stability of the equipment, improving the overall operation continuity and intelligent level.

[0042] During use, first, the entire boom structure is fixed to the excavator main body through the mounting part 101. The base 1011 is arranged on the mounting part 101. The first cylinder 1012 is fixedly connected to the outside of the base 1011 and is used to drive the overall boom to swing up and down. The fixed frame 2011 in the adjustment component 201 is connected to the boom. The second cylinder 2012 is arranged inside the fixed frame 2011, and its output end is connected to the adjustment frame 2013 to control the pitching angle of the adjustment frame 2013. The third cylinder 2014 is arranged inside the adjustment frame 2013 and is connected to the bucket 2015 to realize the attitude adjustment and excavation action of the bucket 2015. During the operation process, each cylinder 1012, 2012, 2014 is electrically connected to the external control system and can realize linkage control according to the preset program or operation instruction, so as to complete accurate and efficient excavation operations. At the same time, the lubrication component 202 works together. The lubrication syringe 2021 is fixedly installed on one side of the adjustment frame 2013 and is connected to the movable connection part of the bucket 2015 through an oil pipeline. The filling port 2022 is arranged on the top of the lubrication syringe 2021 and is equipped with a sealing cover for facilitating regular addition of lubricating oil or grease. The lubrication syringe 2021 is preferably an electric or multi-stage pressure control structure and can automatically deliver grease to key parts such as the rotating joints of the bucket 2015 according to the set cycle, operation time or real-time working conditions, ensuring that the moving parts are always in good lubrication state. In addition, the lubrication component 202 is signal-connected to the control system and can synchronously start the lubrication program when the bucket 2015 performs continuous operations, realizing the full-automatic lubrication function without downtime maintenance, significantly improving the operation stability and operation efficiency of the equipment.
