No-tilt dump box with auger for chip removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional chipper dump boxes require tilting, which leads to inefficiencies and safety hazards due to the need for operators to climb on and off the vehicle, and the necessity of deploying outriggers, resulting in increased time and risk of injury.
Innovation Solution
A no-tilt dump box design utilizing a rotating auger to expel chips from the interior to the exterior, eliminating the need for tilting and allowing the vehicle to move without outriggers, while keeping the operator on the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dump box is tilted to expel chips, then the chips can be dumped from the box, but the operator must climb on and off the vehicle increasing time and risk of injury
Solution Approach 1:
Instead of tilting the dump box to expel chips (conventional approach), the patent inverts the approach by keeping the box level and using a rotating auger to actively transport chips from the interior to the exterior through a discharge opening. This inversion eliminates the need for operator intervention and vehicle movement, resolving the contradiction between operator safety and dumping time.
Solution Approach 2:
The patent replaces the mechanical tilting system with an auger-based mechanical transport system. The auger, driven by a motor, substitutes for the gravitational force that would result from tilting, enabling chip expulsion without box inclination and without requiring operator climbing or vehicle movement.
2Stability of the object's composition
If the outriggers are deployed to stabilize the vehicle during dumping, then the vehicle remains stable, but the process takes more time and requires multiple deployments
Solution Approach 1:
The patent inverts the conventional dumping sequence by eliminating the need for outrigger deployment. Instead of stabilizing the vehicle through outriggers during box tilting, the system maintains vehicle stability while keeping the box level and uses the auger to perform the dumping function, thereby improving productivity without sacrificing stability.
Solution Approach 2:
The patent extracts the outriggers from the dumping process entirely. By using the auger to expel chips horizontally through a side opening, the system removes the need for vehicle stabilization during dumping, allowing continuous operation without the time-consuming cycle of deploying and retracting outriggers.
3Productivity
If the vehicle is moved forward to allow chips to be dumped, then the chips can be expelled from the box, but the process is time-consuming and increases injury likelihood
Solution Approach 1:
The patent inverts the conventional approach where the vehicle moves forward to enable dumping. Instead, the vehicle remains stationary, the box remains level, and the auger rotates to transport chips to the exterior. This inversion allows continuous operation without vehicle movement, eliminating injury risks associated with operator climbing and vehicle maneuvering.
Solution Approach 2:
The auger system performs the dumping function autonomously without requiring operator intervention. The motor-driven auger self-activates to transport and expel chips, enabling continuous chipping operation while the operator remains safely on the ground, thus improving productivity while eliminating injury hazards.
4Ease of operation
If the dump box is tilted repeatedly to remove all chips, then the chips can be completely emptied, but the process increases the likelihood of operator injury
Solution Approach 1:
The patent replaces the repeated mechanical tilting action with a single activation of the auger system. The auger, driven by a motor, substitutes for manual tilting operations, completely removing chips through the discharge opening without requiring the operator to climb or the box to be tilted repeatedly, thus ensuring complete chip removal while maintaining operator safety.
Solution Approach 2:
The auger system autonomously performs the complete chip removal function without requiring repeated operator intervention. Once activated, the motor-driven auger continues rotating to expel all chips from the box, enabling complete emptying while the operator remains safely on the ground, thereby improving both ease of operation and reliability.

Function Achieved in This Case
This solution reduces operator burden, saves time, and enhances safety by allowing continuous operation without tilting, enabling chips to be spread over a larger area without moving the vehicle, thus minimizing injury and operational delays.

AI summary
A dump box configured for mounting on a vehicle and providing a method of extracting chips from the dump box without tilting the dump box is presented. The dump box may receive chips through a first opening on a side and utilize an auger mounted near the floor and in a channel to move the chips through a second opening to the exterior of the dump box.
