Dump Truck Front Baffle Locking for Complete Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic dump trucks face issues with incomplete unloading due to insufficient locking force of the front baffle when dealing with heavy or viscous goods, causing the baffle to retract slowly or synchronously with the bottom plate during unloading.
Innovation Solution
The implementation of an active backstop mechanism using lifting electromagnets and friction plates that interact differently with the side plates based on the movement direction of the bottom plate, ensuring the front baffle remains locked during forward retraction and free during backward movement, enhancing the unloading efficiency and thoroughness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If elastic plates are used to lock the front baffle on the left and right side plates, then the front baffle can be locked during bottom plate retraction, but the locking force is insufficient for heavy or viscous goods causing slow or synchronous retraction
Solution Approach 1:
The patent replaces the mechanical elastic plate locking system with an electromagnetic lifting magnet system. The lifting magnets provide strong magnetic attraction force to securely lock the front baffle during bottom plate retraction, overcoming the insufficient mechanical locking force of elastic plates for heavy or viscous goods, while enabling rapid engagement and disengagement for high-speed unloading.
Solution Approach 2:
The patent changes the locking mechanism from passive elastic force to active electromagnetic force. The lifting magnets can be energized to provide strong locking force when needed and de-energized for rapid release, dynamically adjusting the locking parameter based on operational requirements to achieve both strong holding force and fast response.
2Reliability
If the front baffle is locked tightly during bottom plate retraction, then unloading completeness improves, but the structure becomes more complex
Solution Approach 1:
The lifting magnets serve multiple functions: they act as locking devices during bottom plate retraction, provide backstop support to prevent excessive baffle movement, and can be quickly deactivated for rapid unloading. This multi-functionality reduces the need for separate dedicated components for each function, simplifying the overall structure while improving reliability.
Solution Approach 2:
The lifting magnets are positioned to automatically engage with the front baffle structure, utilizing the existing geometric features of the baffle and side plates. The magnetic attraction naturally engages when the baffle is in the correct position, eliminating the need for complex mechanical linkages or additional actuating mechanisms.
3Force
If elastic plates expand to lock the front baffle, then the baffle can be secured, but the surface becomes unsmooth causing increased friction
Solution Approach 1:
The patent replaces the mechanical elastic plate expansion system with an electromagnetic lifting magnet system. The magnetic field provides locking force without physical contact or surface deformation, maintaining a smooth baffle surface that reduces friction during movement while still providing strong locking capability when energized.

Function Achieved in This Case
This solution ensures rapid and complete unloading of goods by preventing the front baffle from retracting backwards with the bottom plate, improving the unloading process, especially with heavy or viscous materials.
Implementation Method 1
when the bottom plate retracts forwards, the two lifting electromagnets are energized to attract with the left side plate and the right side plate respectively
Implementation Method 2
a portion, between the stopper and an end face of the sleeve, of the telescopic rod is sleeved with a spring
Implementation Method 3
the two friction plates are tightly abutted against the left side plate and the right side plate, respectively

AI summary
Provided is a relay type dump truck including a bottom plate capable of moving backwards and retracting forwards in a reciprocating manner, and a front baffle positioned on the bottom plate and between a left side plate and a right side plate. Differences from the prior art are that: one side, side, close to a truck head, of the front baffle is provided with a backstop mechanism, and the backstop mechanism is free of combining, or establishing mutual attraction with the left side plate and the right side plate when the bottom plate moves backwards, and combines, or establishes mutual attraction with the left side plate and the right side plate when the bottom plate retracts forwards.
