Debris Storage Tank Extension Plate Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing debris removal systems from vehicle-mounted storage tanks require manual spreading of debris in the dump box, leading to inefficient distribution and increased labor costs.
Innovation Solution
A debris storage tank emptying system with an extension plate assembly that moves axially within the storage tank, using extension arms and support arms to push debris evenly into the dump box, reducing manual labor and ensuring even distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual spreading of debris is used in the dump box, then labor costs increase and distribution efficiency decreases, but the existing simple tank structure is maintained
Solution Approach 1:
The extension plate is designed to be movable rather than fixed, allowing it to dynamically extend beyond the tank opening during debris discharge and then retract. This dynamic configuration enables the plate to actively push debris into the dump box, automating the spreading function without requiring a completely complex mechanical system.
Solution Approach 2:
The extension plate utilizes the existing hydraulic pusher plate mechanism to automatically push debris outward, eliminating the need for separate manual spreading operations. The system serves itself by using the same actuation mechanism (hydraulic pusher plate) to both contain debris during transport and distribute it during discharge.
2Ease of operation
If extension plate is added to automate debris distribution, then manual labor is reduced and distribution evenness is improved, but device complexity increases
Solution Approach 1:
The extension plate mechanism is divided into distinct functional segments: the extension plate itself, the extension arm for positioning, and the support arm for stabilization. This segmentation allows each component to perform its specific function independently while simplifying the overall design and maintenance of the system.
Solution Approach 2:
The extension plate operates in a dimensional extension beyond the tank opening, utilizing the spatial dimension outside the tank to achieve debris distribution. By extending the functional workspace outward, the system automates spreading without adding complex internal mechanisms within the tank confines.
3Productivity
If extension arm is used to position extension plate, then debris pushing capability is enhanced, but structural complexity and potential failure points increase
Solution Approach 1:
The extension arm serves as an intermediary mechanical element between the hydraulic pusher plate and the extension plate. It transfers the pushing force from the hydraulic system to the debris while providing necessary positioning and movement control, thereby enhancing discharge speed without directly complicating the hydraulic system itself.
Solution Approach 2:
The extension arm is designed with dynamic positioning capability, allowing it to adjust its position and angle during the debris discharge process. This dynamic adjustment optimizes the force transmission to debris, enhancing discharge efficiency while maintaining mechanical simplicity through adaptive geometry rather than complex actuation.

AI summary
An extension plate assembly for dumping debris into a dump box from a storage tank mounted on a trunk. The storage tank is fitted with a pusher plate that both compacts and pushes debris out of the back of the storage tank. The extension plate apparatus includes extension arms that are rotatably attached on one end to the pusher plate and rotatably attached on the other end to an extension plate. When the pusher plate is in its rearward most position, the extension arms extend beyond the edge of the storage tank. The extension plate assembly allows debris to be pushed out of the storage tank and distributed more evenly into a dump box.
