Excavator Bucket Retaining Device for Rapid Mode Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excavator buckets require time-consuming assembly and disassembly to switch between backhoe and front loader modes due to the need for repositioning bolts and different mounting angles, hindering rapid operation changes.
Innovation Solution
An excavator bucket design featuring a retaining device with two bolts and collinear bolt receptacles allows for quick conversion between backhoe and front loader modes without repositioning, using the same bolt receptacles for both operations, optimizing kinematics and simplifying the conversion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate front loader and backhoe buckets are used with mechanical quick couplers, then the excavator can be adapted to different applications, but assembly and disassembly are time-consuming
Solution Approach 1:
The bucket is divided into two separate buckets (front loader bucket and backhoe bucket) that can be independently attached to the retaining device, allowing rapid switching between applications without full disassembly
Solution Approach 2:
The retaining device incorporates movable mounting bolts that can be repositioned along guide slots to accommodate different mounting positions required for front loader and backhoe operations, enabling dynamic adaptation without time-consuming reconfiguration
2Adaptability or versatility
If combi buckets are used that can function as both backhoe and front loader buckets, then versatility is improved, but switching between operating modes requires time-consuming repositioning of mounting bolts
Solution Approach 1:
The mounting bolts are designed to be movable along guide slots in the retaining device, allowing them to be quickly repositioned between different mounting positions for front loader and backhoe modes without complete disassembly or complex reconfiguration
Solution Approach 2:
The retaining device is designed with universal mounting features that can accommodate both front loader and backhoe buckets through the same basic structure, with only minor bolt repositioning required to switch between operating modes
3Adaptability or versatility
If multiple bolt receptacles are provided on the bearing block for different mounting positions, then both front loader and backhoe operations are enabled, but the structure becomes more complex
Solution Approach 1:
The mounting system is segmented into a retaining device with integrated bolt receptacles and a bearing block with guide slots, separating the functions of position adjustment from the main bucket structure
Solution Approach 2:
The retaining device acts as an intermediary component between the bucket and the quick coupler, incorporating all necessary mounting features and bolt repositioning mechanisms in a single integrated unit that simplifies the overall structure

AI summary
The disclosure relates to an excavator bucket, which can be used both as a front loader bucket and as a backhoe bucket. The excavator bucket comprises a shell delimiting a bucket volume and a retaining device connected to the shell, via which the excavator bucket can be detachably connected to a quick coupling device of an implement. The retaining device comprises a first bolt for establishing a first connection to the quick coupling device and bolt receptacles arranged in a collinear manner to each other for establishing a second connection to the quick coupling device. According to the disclosure, the retaining device further comprises a second bolt, by means of which the first connection to the quick coupling device can be established as an alternative to the first bolt, wherein the second bolt is arranged on a side of the bolt receptacles opposite to the first bolt when viewed from above the retaining device. The bolts are arranged such that the second connection can be established via the same bolt receptacles, both when using the first bolt and when using the second bolt. The disclosure further relates to a method for converting the excavator bucket according to the disclosure between a backhoe bucket operation and a front loader bucket operation.
