Mobile Screening Assembly Height and Inclination Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile bulk material processing apparatuses lack a mechanism to adjust both the height and inclination of screening assemblies efficiently, leading to transportation and operational challenges, as well as increased cost and weight due to the need for longer base frames.
Innovation Solution
A mobile screening assembly with two pivotable linking elements and hydraulic cylinders allows for adjustable height and inclination, enabling compact folding for transport and easy operation, using pivot joints and hydraulic actuation for flexible positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pivotable joint mechanism is used to change the position of the screen, then the device complexity is reduced, but the ability to adjust both height and inclination is lost
Solution Approach 1:
The position adjustment mechanism is segmented into two independent pivotable joints: a first pivotable joint for adjusting the inclination angle of the screening assembly, and a second pivotable joint for adjusting the height of the screening assembly. This segmentation allows each joint to perform a specific adjustment function, achieving both height and inclination adjustment capabilities while keeping each individual joint relatively simple in design.
2Adaptability or versatility
If the base frame length is increased to accommodate height adjustment mechanisms, then the height adjustment capability is improved, but the transportation compliance and cost increase
Solution Approach 1:
The base frame is designed with a pivotable connection rather than a fixed rigid connection. The screening assembly is connected to the base frame through a second pivotable joint that allows vertical movement and height adjustment. This dynamic connection enables the screening assembly to be raised or lowered relative to the base frame without requiring an extended base frame structure, thus maintaining compact dimensions for transportation while achieving height adjustment capability during operation.
3Object-affected harmful factors
If the screening assembly is kept in horizontal orientation during transport, then transport regulations compliance is improved, but the setup time for operational positioning increases
Solution Approach 1:
The screening assembly is pre-configured with two pivotable joints that enable quick adjustment between horizontal transport orientation and inclined operational orientation. The first pivotable joint is pre-positioned to allow inclination adjustment, and the second pivotable joint is pre-positioned to allow height adjustment. This preliminary configuration of the adjustment mechanism allows for rapid repositioning during setup, reducing the time required to transition from transport to operational position while maintaining compliance with transport regulations when horizontal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates optimal material transfer, complies with transport regulations, reduces setup time, and enhances safety during operation and transport by allowing precise adjustment of the screening assembly's position without increasing the base frame length.
Implementation Method 1
The position adjustment mechanism comprises a pair of extendible and retractable first hydraulic cylinders attached to the base frame, configured to swing the first linking element away from the base frame
Implementation Method 2
a first linking element having a forward end and a rear end, said first linking element being movably connected to the base frame via a first attachment means arranged with the base frame allowing a first tilt angle to be set between the base frame and the first linking element

AI summary
The present disclosure provides a screening assembly for a mobile bulk material processing apparatus (100), capable of adjustment of its position with respect to the base frame (102) of the mobile bulk material processing apparatus in order to facilitate the transfer of material from the screen (120) on to the processing unit, like crusher, by optimizing the height and the angle of operation of the screening assembly. The screening assembly hereby disclosed is also capable of being folded into a compact arrangement which is compliant to transport regulations, while also being convenient and safe for the operators. The screening assembly comprises a base frame (102), and at least two linking elements (107, 111) coupled at pivotable joints in such a way that when in operational position, the two linking elements are configured to adjust the height and the angle of inclination of the screen box (3) to facilitate transfer of material from the screen to the crusher.
