Telescopic Chute for Mobile Screening Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile screening apparatuses for mineral materials face challenges in efficiently transporting and positioning chutes, which require manual handling and can be damaged during movement due to their manual removal and reinstallation process.
Innovation Solution
A transportable mineral material processing system with a telescopically movable and pivotably connected chute that can transition between operating and transport states, where the chute's weight is supported by the dividing hopper, allowing automatic retraction and extraction mechanisms to manage its position relative to the platform frame, enabling seamless movement between operating and transport configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If chutes are manually removed and transported, then they can be repositioned to convenient locations, but manual handling requires labor and risks damage to the chutes
Solution Approach 1:
The chute is designed with telescopic sections that allow it to extend and retract automatically during transport and operation. The chute transitions from a retracted state during transport to an extended state during operation, eliminating the need for manual removal and reinstallation while reducing damage risk
Solution Approach 2:
The chute system incorporates automatic extension and retraction mechanisms that operate without human intervention. The chute extends automatically when the screen moves to the operating position and retracts automatically during transport, making the system self-servicing and eliminating manual handling requirements
2Volume of moving object
If the screen is pivoted down onto a body for transport, then transport dimensions are reduced, but chutes may be crushed between moving parts if not removed
Solution Approach 1:
The chute incorporates telescopic sections that automatically retract to a compact configuration when the screen is pivoted down for transport. This dynamic adjustment ensures the chute does not protrude or interfere with moving parts, preventing crushing while maintaining the ability to extend to full length during operation
Solution Approach 2:
The chute retraction mechanism is designed to automatically activate before the screen pivots down for transport. The chute retracts in advance of the closing movement, ensuring it is in a protected position before any crushing risk occurs, and extends in advance when the screen moves to the operating position
3Adaptability or versatility
If removable chutes are used to guide fractions to convenient positions, then material can be directed to separate piles, but the chutes require manual removal and separate transport
Solution Approach 1:
The chute is permanently integrated with the screen structure through telescopic connections, combining the screening function with the material diversion function in a single unified system. The chute remains attached to the screen during both transport and operation, eliminating the need for separate transport of chutes while maintaining the ability to direct material to different positions

AI summary
A method and system adapting a mineral material crushing system (100) between operating and transport configurations. A screen support frame (120) receives and supports a multideck screen (130) with a plurality of stacked screen decks outputting different size fractions at a discharge end. A dividing hopper (150) receives different size fractions from the multideck screen). A chute (152) guides the different size fractions to a chute output position. A platform frame (110) movably supports the screen support frame (120) allowing the screen support frame (120) and the multideck screen (130) move between an elevated operating position and to a lowered transport position. The chute output position laterally resides outside a lateral footprint bordered by the platform frame. The chute (152) moves between chute transport and operating states so that at least a portion of its weight remains carried by the dividing hopper (150).
