Backhoe Loader Rotating Platform Layout for Continuous Digging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backhoe loaders suffer from inefficient digging operations due to the need for seat adjustments during switching between loading and excavating modes, limited operation range, inflexible arm rotation, and poor operator visibility and control.
Innovation Solution
A backhoe loader design featuring a 360° rotating control platform and a 180° rotating excavating device, with a cab and excavating bucket configuration that allows 360° excavating and bidirectional driving, enhancing operator visibility and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat is adjusted 180° to face the excavating device for excavating operation, then the operator can observe the excavating device, but the operation becomes tedious and time-consuming with low efficiency
Solution Approach 1:
The backhoe loader is divided into two independent rotatable components: the control platform (carrying the cab) that rotates 360° relative to the vehicle body, and the excavating device that rotates 180° relative to the cab. This segmentation allows each component to rotate independently, eliminating the need for the operator to adjust the seat while maintaining continuous observation of the excavating device during operation.
Solution Approach 2:
The patent implements dynamic rotation capabilities where the control platform can rotate 360° and the excavating device can rotate 180°, allowing the system to adapt its configuration during operation. This dynamic adjustability enables the operator to maintain a fixed seating position while the excavating device moves independently into different working positions, improving operational efficiency.
2Adaptability or versatility
If the excavating arm rotates 180° at most, then the structure remains compact, but the rotation is inflexible and the operation range is limited
Solution Approach 1:
The patent adds a second rotational dimension by implementing a control platform that rotates 360° relative to the vehicle body, in addition to the excavating device's 180° rotation relative to the cab. This two-dimensional rotation system expands the operation range from a single arc to a comprehensive three-dimensional working space, while maintaining compact structure through controlled rotation angles of each component.
3Device complexity
If the cab is positioned close to the excavating device connection point, then the structure is compact, but the operator's field of view and sense of control are poor
Solution Approach 1:
The patent separates the cab (operator's station) from the excavating device connection point by introducing a rotatable control platform as an intermediate structure. The cab is positioned on the control platform, which can rotate independently, allowing the operator to be located away from the excavating device connection point while maintaining visual contact and control through the platform's rotation capability.

AI summary
The present disclosure relates to a backhoe loader for efficient digging. The backhoe loader includes: a vehicle body, including a first vehicle body and a second vehicle body which are connected sequentially; a loading device, arranged on the first vehicle body; a control platform, arranged on the second vehicle body and configured to rotate by 360° relative to the second vehicle body; a cab, arranged on a first side of the control platform; and an excavating device, arranged on a second side of the control platform opposite to the first side, the excavating device being configured to rotate by 180° relative to the cab. The backhoe loader can realize functions of 360° excavating and bidirectional driving. When the excavating device works, the backhoe loader can be directly moved by folding stabilizers and without changing the position of a seat back and forth, so that the excavating efficiency is improved; and an operator in the cab has a wide field of view, operation feeling is good, the backhoe loader has a compact structure, and the stability of the machine body is high.
