Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanized sampling systems for trains face issues such as material bulking due to high moisture, sieve plate blockage, uneven sample division, material mixing, long transportation distances leading to moisture loss, and manual handling of discarded materials.
Innovation Solution
A non-belt automatic mechanized sampling system for trains that includes a slide rail, sampling mechanism, integrated sample preparation component with a discharging mechanism, feeder, crusher, constant mass dividing machine, and sample retention barrel, which eliminates belts for conveying materials and uses blowing devices to prevent material accumulation and mixing, and automated handling of discarded materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If belt conveyors are used to transport materials, then material transportation is achieved, but material bulking occurs due to high moisture and sieve plate blockage
Solution Approach 1:
The patent extracts and removes the belt conveyor system from the sampling mechanism, eliminating the source of material bulking and sieve plate blockage. Materials are now discharged directly from the sampling head into containers without intermediate belt transport, solving the reliability issues caused by moisture-induced bulking on belts.
Solution Approach 2:
The mechanical belt conveyor system is replaced with a direct gravity-fed discharge mechanism. Materials flow directly from the sampling head through a chute into containers, eliminating the mechanical belt system that caused bulking and blockage problems.
2Ease of operation
If manual handling of discarded materials is used, then labor flexibility is maintained, but labor intensity increases and operational efficiency decreases
Solution Approach 1:
The system implements self-service by automatically discharging discarded materials through a dedicated discharging mechanism. The sampling head automatically separates and ejects unwanted materials without requiring manual intervention, allowing the system to service itself and improving productivity while maintaining operational simplicity.
Solution Approach 2:
A discharging mechanism acts as an intermediary between the sampling head and the external environment for discarded materials. This intermediary component automatically handles the ejection of unwanted materials, eliminating the need for manual handling while maintaining system simplicity.
3Adaptability or versatility
If long transportation distances are used for materials, then sampling coverage is improved, but moisture loss increases
Solution Approach 1:
The patent extracts the long-distance belt transport环节 from the system, eliminating the prolonged exposure time that causes moisture loss. Materials are sampled and processed in-place or with minimal movement, directly from the sampling head to containers, removing the source of moisture loss during transport.
4Quantity of substance
If belt conveyors are used for material transport, then material handling is achieved, but material mixing occurs and representativeness decreases
Solution Approach 1:
The mechanical belt conveyor system is replaced with a direct gravity-fed discharge path. Materials flow directly from the sampling head through a chute into containers without being conveyed on belts, eliminating the mixing that occurs during belt transport and preserving sample representativeness.

AI summary
Provided is a non-belt automatic mechanized sampling system for a train, including: a working platform provided with a slide rail; a sampling mechanism slidably arranged on the slide rail and configured to collect materials from the carriage of the train; an integrated sample preparation component including a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel arranged from top to bottom. The feeder transports the material to the crusher. The crusher crushes the material and transports the crushed material to the constant mass dividing machine. The constant mass dividing machine divides the crushed material into samples to the sample retention barrel, and the discarded material to the discharging mechanism. The discharging mechanism transports the discarded materials to the carriage.
