Solution Overview

Problem

Mobile crushing plants face challenges in flexibility and stability due to varying material loads and loading devices, leading to potential overloading and inefficiencies in operation, as existing designs are tailored to specific materials and devices, limiting their adaptability and increasing the risk of damage from dynamic forces.

Innovation Solution

The design allows for interchangeable receiving bunkers with different volumes and loading heights, which can be attached to the supporting structure at various positions to adjust the center of gravity and absorb dynamic loads, using detachable form-fitting connections and adjustable boundary walls to accommodate different loading scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the receiving bunker is designed for a specific loading device and material type, then the crushing plant achieves optimized performance for that specific application, but the plant cannot be operated with different chargers or materials

Engineering Contradiction:
Improvereliable continuous operationVSAvoidoperation with different chargers and materials
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The receiving bunker is divided into modular sections that can be independently attached or detached from the supporting structure. This segmentation allows different bunker configurations to be used with different loading devices while maintaining optimized performance for each specific application.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting structure includes adjustable connection points that allow the receiving bunker to be positioned at different locations dynamically. This enables the plant to adapt to different loading devices and material types by reconfiguring the bunker position rather than being fixed in a single optimized position.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If the receiving bunker volume is increased to provide buffer function for discontinuous discharge, then the plant can handle larger shovel volumes, but the static and dynamic forces increase disproportionately

Engineering Contradiction:
Improvereceiving bunker volumeVSAvoidstatic and dynamic forces
Core Design Contradiction:
Quantity of substanceVSForce

Solution Approach 1:

The receiving bunker is designed as modular sections that can be attached in different quantities or configurations. This allows the buffer volume to be adjusted to match the specific loading device being used, rather than always having maximum volume, thereby reducing unnecessary static and dynamic forces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows changing the effective receiving bunker volume by attaching or detaching modular sections, thereby adjusting the buffer function to match the actual loading requirements. This prevents excessive volume from creating disproportionate forces when smaller loading devices are used.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If the receiving bunker is positioned further from the crusher to accommodate larger loading heights, then larger shovel volumes can be used, but the dynamic loads and risk of plant swinging increase

Engineering Contradiction:
Improveloading height and shovel volumeVSAvoiddynamic loads and plant swinging
Core Design Contradiction:
ProductivityVSForce

Solution Approach 1:

The supporting structure provides adjustable connection points that allow the receiving bunker to be positioned at different distances from the crusher dynamically. This enables optimization of the balance between loading height (for productivity) and distance from the crusher (to minimize dynamic loads and swinging).

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustable positioning system allows the receiving bunker to be pre-positioned at the optimal distance from the crusher based on the specific loading device being used. This preliminary configuration prevents excessive dynamic loads before operation begins.

Inventive Principle:
Principle #10Preliminary action

4Ease of manufacture

If the crushing plant is designed with fixed components for specific throughput requirements, then costly oversizing during production is avoided, but the plant cannot be adapted to different throughput requirements

Engineering Contradiction:
Improveavoid costly oversizingVSAvoidadaptation to different throughput requirements
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The receiving bunker is designed as modular sections that can be attached or detached to adjust the overall system capacity. This allows the plant to be manufactured with base components for specific throughput requirements without oversizing, while still adapting to different requirements by adding or removing modular sections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting structure with multiple connection points serves multiple functions: it provides structural support, enables positioning adjustment for different bunker configurations, and allows adaptation to different throughput requirements. This universal design avoids the need for multiple specialized structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a mobile crushing system, comprising a chassis (1), a receiving bin (5a, 5b), a crusher (2), and an apron conveyor (4), which is arranged on a supporting structure (3), for conveying the material to be crushed from the receiving bin (5a, 5b) to the crusher (2), wherein the receiving bin (5a, 5b) is fastened to connection points (8) of the supporting structure (3). According to the invention, the receiving bin (5a, 5b) can be modularly exchanged. According to a first aspect, the apron conveyor (4) extends beyond a bottom of the receiving bin (5b) in a direction opposite the conveying direction (F) by means of section (9) designed to receive the material to be crushed, and the supporting structure (3) has free connection points. According to a further aspect, the receiving bin (5a, 5b) can be removed from the apron conveyor (4) along specified separation surfaces.
