Drilling Bucket Impact Wall Reversing Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drilling buckets struggle with emptying cohesive ground materials like clay, which tend to stick due to adhesive forces and suction, requiring time-consuming manual intervention and compromising safety during the drilling process.
Innovation Solution
Incorporating at least one impact wall within the drilling bucket's internal space that extends along its axial length, allowing for reversing rotation to press ground material against the wall, reducing negative pressure and adhesive forces, facilitating easier loosening and automatic emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the drilling bucket is filled with cohesive ground material like clay, then the filling level can be increased, but the ground material sticks to the drilling bucket due to adhesive forces and suction, making emptying difficult
Solution Approach 1:
The patent applies mechanical vibration through a vibratory device (200) that generates vibrations in the drilling bucket (10). These vibrations disrupt the adhesive forces and suction between the cohesive ground material and the drilling bucket surface, enabling the material to be dislodged and emptied effectively even at high filling levels.
Solution Approach 2:
The patent replaces manual mechanical intervention (staff manually freeing the bucket) with an automated vibratory mechanism. The vibratory device (200) substitutes human labor by generating controlled vibrations that automatically dislodge adhering ground material, making the emptying process safer and more efficient.
2Ease of operation
If vibration is applied to dislodge adhering ground material, then emptying can be achieved, but it may not be sufficient for highly cohesive materials, requiring manual intervention
Solution Approach 1:
The drilling bucket is equipped with a self-service emptying mechanism in the form of a vibratory device (200) that automatically dislodges and empties cohesive ground material without requiring external manual intervention. The system serves itself by generating the necessary vibrations to clear its own contents, eliminating process interruptions.
Solution Approach 2:
The vibratory emptying mechanism enables continuous operation of the drilling process by preventing interruptions. The vibratory device (200) ensures complete emptying of cohesive materials, allowing the drilling bucket to be immediately reused without manual cleaning delays, thus maintaining continuous productive action.
3Reliability
If manual cleaning is performed to free the drilling bucket, then complete emptying can be achieved, but it is time-consuming and cost-intensive
Solution Approach 1:
The patent replaces manual mechanical cleaning with an automated vibratory system (200). This substitution eliminates the need for staff to manually free the drilling bucket, reducing labor costs and increasing drilling efficiency while ensuring complete emptying of cohesive ground materials through controlled vibrations.
Solution Approach 2:
The drilling bucket performs its own emptying function through the integrated vibratory device (200), eliminating the need for external manual intervention. This self-service capability ensures reliable complete emptying while maintaining high productivity by avoiding time-consuming manual cleaning operations.
4Ease of operation
If staff manually free the drilling bucket from adhering ground material, then the bucket can be emptied, but work safety is compromised due to entry into the operating range
Solution Approach 1:
The drilling bucket is equipped with a self-service vibratory emptying device (200) that eliminates the need for staff to enter the hazardous operating range. The system automatically dislodges and empties cohesive ground material through vibrations, ensuring complete emptying capability while maintaining work safety by keeping personnel clear of the drilling apparatus operating zone.
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
This solution significantly reduces the need for manual emptying, enhancing work safety and efficiency by compacting and deforming the ground material, allowing for reliable and efficient operation of the drilling bucket.
Implementation Method 1
ground material received in the drilling bucket is pressed against at least one impact wall and, in doing so, the ground material is specifically compacted and deformed
Implementation Method 2
cohesive ground material, such as clay... the ground material can remain stuck in the drilling bucket and does not simply fall out... due to adhesive forces
Implementation Method 3
the ground material can remain stuck in the drilling bucket and does not simply fall out of the internal space under the effect of gravity
