Solution Overview

Problem

Existing movable crushing apparatuses face challenges with side conveyors that complicate transportation due to their need for hydraulic detachment, separate transport, and safety risks, requiring multiple workers and additional equipment.

Innovation Solution

A pivotable side conveyor mechanism that allows manual pivoting and locking into various positions without hydraulic actuators, maintaining connected hoses and cables, and eliminating the need for lifting devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the side conveyor is folded to the side of the machine during transportation using hydraulic cylinders and joints, then the transportation width is reduced, but the device complexity increases and safety risks arise

Engineering Contradiction:

Improvetransportation widthVSAvoidstructure complexity

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The invention extracts and removes the hydraulic cylinders and joints from the side conveyor structure, replacing them with a simpler manual folding mechanism. This eliminates the complex hydraulic system while achieving the same transportation width reduction goal through a more straightforward mechanical design.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the hydraulic mechanical system with a pure mechanical manual folding system. By using manual effort instead of hydraulic power, the system achieves the folding function with fewer components, reduced complexity, and eliminated hydraulic hoses that pose safety risks.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the side conveyor is entirely detached from its fastening points for changing sides, then the side conveyor can be repositioned, but the time required and safety risks increase

Engineering Contradiction:

Improveside change capabilityVSAvoidrepositioning time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention incorporates pre-designed fastening points and a standardized quick-connection mechanism that allows the side conveyor to be rapidly repositioned from one side of the machine to the other. The preliminary design of the fastening system enables quick attachment and detachment without requiring complete disassembly, significantly reducing repositioning time.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If hydraulic hoses are detached when transporting the side conveyor separately, then the conveyor can be moved, but safety risks for persons and the environment increase

Engineering Contradiction:

ImprovetransportabilityVSAvoidsafety risks

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and removes the hydraulic hoses from the side conveyor system entirely, replacing the hydraulic-powered conveyor with a manual folding and transport mechanism. This eliminates the safety risks associated with detached hydraulic hoses while maintaining the ability to transport the side conveyor easily.

Inventive Principle:

Principle #2Taking out (Extraction)
