Cubic Mixing Drum with Low-Tail Support for Concrete Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concrete mixing carriers have a reduced loading capacity and are prone to lateral rollover accidents due to their high center of gravity and cylindrical fusiform structure.
Innovation Solution
A concrete mixing carrier with a cubic, horizontally supported mixing drum and a hinged rear support, featuring a lifting mechanism to adjust the drum's position during unloading, and a rotary inner drum with movable blades and a drive gear system for efficient mixing, which also includes inclined end plates and water stop belts for improved operation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mixing drum is made with a cylindrical fusiform structure and the tail is raised high, then the concrete can be easily unloaded, but the loading capacity is greatly reduced and the vehicle is prone to lateral rollover due to high center of gravity
Solution Approach 1:
The patent inverts the traditional high-tail design by lowering the rear support point below the drum axis, creating a low-tail structure. This inversion resolves the contradiction by enabling easy unloading through the low tail configuration while simultaneously lowering the center of gravity to prevent rollover and increase loading capacity.
Solution Approach 2:
The patent changes the vertical dimension of the drum support configuration by positioning the rear support below the drum axis rather than above or at the same level. This dimensional change allows the drum to achieve both easy unloading capability and low center of gravity stability simultaneously.
