Rotating Panel Bucket for Loading and Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for filling large-sized buckets in loading and transport devices face challenges such as material rolling back, limited loading capacity due to center of gravity outside the wheelbase, and low productivity from material shifting in one layer, preventing full filling and efficient material transfer.
Innovation Solution
A device with a panel connected to the bucket's bottom edge via pivots, rotatable by power units, allows material to shift to the rear part of the bucket, enabling full filling by transferring the bucket forward and rotating the panel to lift and shift material, thereby transferring the center of gravity onto the wheelbase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the bucket is rotated to its upper position to shift material to the rear part, then material can be shifted to the rear part of the bucket, but when lowering the bucket again to the loading position, the material rolls back to the tip part of the bucket and prevents new material from accessing the bucket
Solution Approach 1:
The bucket bottom is segmented into a front part and a rear part by introducing a panel that can rotate independently. This segmentation allows the front part to remain accessible for new material while the panel lifts and shifts material to the rear part, preventing material rollback and enabling continuous loading.
Solution Approach 2:
The panel is made dynamically movable through rotation around pivots, transitioning from a horizontal position (allowing material passage) to an inclined position (lifting and shifting material). This dynamic adjustment enables the system to adapt between material intake and material redistribution functions.
2Quantity of substance
If a larger bucket is used in relation to the machine size, then the loading and transport volume of material increases, but the centre of gravity of the bucket is outside the wheelbase and the rear end of the machine lifts up
Solution Approach 1:
The invention changes the spatial distribution parameter of the load by shifting material to the rear part of the bucket. This rearward weight distribution moves the center of gravity within the wheelbase, maintaining machine stability while enabling the use of larger buckets with increased loading volume.
3Productivity
If a panel shifting material is articulated in the top part of the bucket, then material can be shifted, but the addition in material quantity to the bucket provided by the panel is very small as the material shifts to the bucket already by pushing the bucket as one layer
Solution Approach 1:
The panel is positioned at the bottom of the bucket rather than the top, operating in a previously unused spatial dimension. By rotating the panel from horizontal to inclined position, it creates a lifting action that moves material vertically and rearward, enabling multi-layer loading and significantly increasing the material quantity that can be added to the bucket.
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
Enables quick and efficient filling of large buckets, achieving loading capacity equivalent to the machine's weight and improving transport characteristics by shifting material to the rear part, allowing for larger loads and increased productivity.
Implementation Method 1
the panel is rotatable by means of the power units around the pivots substantially to the middle of the bucket, whereby it is arranged to lift and shift the material being on top of the panel to the rear part of the bucket
Implementation Method 2
the bucket is tillable to be full by pushing forward and rotatable around a horizontal shaft such that the centre of gravity of the bucket transfers onto the wheelbase of the loading and transport device

AI summary
The invention relates to a device for filling a bucket in a loading and transport device (1) to the rear part of a frame structure of which are articulated arms (3a and 3b) rotatable by power units (7), and to second arms (3b) of which is attached by pivots (4) a bucket (2) which is in a transport position rotatable by power units (8) around pivots (4) to an emptying position. According to the invention, in the middle part of the bottom of the whole bucket (2) is connected by pivots (10) a panel (9) to the bottom edge of which are fastened arms (11) which are rotatable by power units ( 12) such that, the panel (9) being against the bottom of the bucket (2), material shifts when pushing the bucket forward without obstacles to the bucket (2), the bucket (2) being most suitably hall-way full, the panel (9) is rotatable around pivots (10) substantially to the middle of the bucket (2), whereby it is arranged to lift and shift material being on top of the panel (9) to the rear part of the bucket (2), after which, the front part of the bucket bottom is empty and the bucket (2) is fillable by pushing forward and rotatable around a horizontal shaft (5) such that the centre of gravity of the bucket (2) transfers onto the wheelbase of the loading and transport device.
