Background

A mechanized sampling machine is a mechanical device that is capable of obtaining a test result from a batch of material to represent a sample of the entire batch of material being sampled. The sampling machines are various in types, and the structural forms of the sampling machines adopted in different industries and different places are different. The system integrates units such as sampling, crushing, division, collection, material abandoning and the like into a whole, has reasonable structure, reliable operation and convenient operation, is widely applied to the railway transportation field of solid minerals such as coal, coke, steel and the like, can complete sample collection and primary sample preparation on the bulk solid mineral materials transported by the railway when the bulk solid mineral materials are unloaded or loaded from a factory, and provides representative samples meeting the weight specified by corresponding national standards for sample preparation in a laboratory in the next step. Therefore, the representativeness of the sampling samples is the core index for determining the mechanized sampling system of the train.

From the aspect of functional division, the mechanized sampling system of the train is mainly divided into a sampling unit and a sample processing unit. The sampling unit has the main function of taking samples with preset weight at the designated horizontal and depth positions of the train carriage according to the setting of a self-control program; the sample processing unit has the main functions of crushing, dividing and the like the sample collected by the sampling unit according to the national standard requirement, preparing the sample into a reserved sample with certain granularity and weight for the laboratory to use, and returning the remaining sample to the designated position in a certain mode.

The sampling unit comprises a drilling type sampling head and a moving and lifting device of the sampling head. The existing sample processing unit comprises a crusher, a division belt conveyor and a scraping and sweeping division device, and the crusher mostly adopts a horizontal crusher with a sieve plate. After the ore sample is extracted by the drilling type sampling machine, the ore sample falls into a receiving hopper of a feeding machine, then is conveyed by a closed feeding belt conveyor to enter a crusher (the crusher is usually positioned in the middle of the closed feeding belt conveyor), the crushing operation of the ore sample is completed by the crusher, the crushed ore sample enters a division belt conveyor, the division belt conveyor carries out primary division while conveying, and is conveyed to a scraping and sweeping division device by the division belt conveyor, then the crushed ore sample is subjected to secondary division and sample retention by the scraping and sweeping division device, redundant ore sample is continuously conveyed to a surplus material processing system through the division belt conveyor, and is returned to a carriage of a train or directly discharged to a mine yard by the surplus material processing system. The material is all circulated by belt drive in whole system appearance link.

2) And the horizontal crushing mode with the sieve plate can cause the meshes of the sieve plate to be easily blocked after long-time use, thereby influencing the subsequent sample preparation precision.

3) And the belt is used as a material conveying mode, so that sample residues and mixing of different batches are easily caused.

4) And the horizontal crushing mode with the sieve plate screens out the materials with the granularity larger than the meshes of the sieve, thereby influencing the representativeness of subsequent samples to a certain extent.

5) When the division belt feeder contracts, will be higher than the material that belt upper surface set up the height through the scraper blade and strike off, only keep setting up the material below the height, but this division mode leads to the division inhomogeneous easily, causes whole system bias great.

6) The material is all circulated by belt drive in whole system appearance link, and the distance of carrying is longer, and the moisture loss in the material is great.

7) The sample after the division of present scraping and scanning divider is usually collected in staying the appearance bucket, but the abandon material after the division is piled up usually on scraping and scanning divider next door, when abandon material is more, will need the manual work to carry elsewhere.
