Abstract
The utility model relates to a coal flow sampling device and comprises a motive power pushing rod, a connecting mechanism, a coal flow sampling blocking plate, a bearing material hopper, etc. The sampling blocking plate is provided with a sampling port and is positioned at the point of the rolling barrel of the end part of a leather belt and in the coal flow of the rolling barrel falling. When the sampling blocking plate transversely cuts the coal flow to make the reciprocating movement, the coal flow sampling device has simple structure, complete function and small system measurement error through the sampling of the sampling port. The coal flow sampling device can be used for various belt conveying systems.
Description
The present invention relates to the coal sampler of a kind of coal sampling apparatus, particularly coal conveying belt system.
For understanding the quality and the characteristic of coal, must carry out sample analysis to it, normally from a collection of coal (several kilotons of as many as and even up to ten thousand ton) take a small amount of coal (tens to the hundreds of kilogram) as coal sample, with the analysis result of this sample, go to estimate the quality and the characteristic of a collection of coal.And sample analysis result's degree of accuracy depends on the representativeness of sample to a great extent, and is representative preferably for coal sample is had, sample with manual method, its labour intensity is very big, but also is easy to generate artificial sampling system error, therefore should adopt the mechanical sampling method as far as possible.At present, using more mechanical sampling device in the coal conveying belt system is the scraper-type sampler, this sampling thief mainly contains power push-rod, swing arm and coal scraper plate and forms, sampler is installed in the middle part of belt, the swing arm of sampling thief drives scraper plate, moves along the direction vertical with belt, when scraper plate vertically crosses to the process of a side from a side of belt, scraper plate scrapes a coal cutting contained on the belt, is coal sample.Adopt the scraper plate sampler to take a sample on belt, because coal is loose coal charge, scraper plate can not all scrape this coal cutting on the belt in the process that promotes sampling, and therefore this coal coal sample that sampler is got is representative relatively poor.
The purpose of this utility model is will invent a kind ofly can improve sample integrity, representativeness on function, reduces the systematic sampling error, is adapted to the mechanical coal sample sampling apparatus that the coal conveying belt system adopts.
The utility model is to realize like this, coal stream sampling apparatus is by power push-rod, coupling arrangement, compositions such as coal stream sampling baffle and sampling hopper, coal stream sampler is installed in belt front end cylinder place, sampling baffle is an one flat plate, one thief hatch is arranged on the flat board, sampling baffle places under the cylinder among the coal breakage stream, power push-rod drives sampling baffle by coupling mechanism and moves reciprocatingly in coal stream, when sampling baffle is done the to-and-fro movement of cutting coal stream in coal stream, when its thief hatch arrives coal stream, a small gangs of of following coal breakage stream derived by sample tap, enter the sampling hopper, thief hatch continues motion until leaving coal stream, finishes an one way sampling process, once be double stroke back and forth, can adopt two increments.Because sampling thief can be realized the sampling of whole coal stream, thereby has improved integrality, the representativeness of sampling, and reduced the sampling error of system.
The utility model can also be realized like this, sampling baffle central authorities open a square hole, as thief hatch, one controllable register is arranged on the sampling baffle, in order to regulate the size of thief hatch, make its thieff hatch lateral dimension by conveying coal maximum particle size 2.5-3 doubly, thieff hatch length can contain the conveying coal and flow down the maximum ga(u)ge of falling the sampling baffle place.
The utility model can also realize like this that sampling baffle fixedlys connected with a leverage, power push-rod promotes lever, the to-and-fro movement of lever drives sampling baffle, the arm of force and the weighing arm of lever have length adjustment device, by adjusting the length of the arm of force and weighing arm, regulate reciprocating range of sampling baffle and movement velocity, and guarantee the width of sampling baffle range greater than belt conveyor.
Sampling baffle of the present utility model can be with wear-resisting steel plate or wear-resisting engineering plastics manufacturing, also can be with the general steel plate manufacturing but especially be subjected to coal face surfacing one deck wear-resistant coating.
The utility model is simple in structure, and is multiple functional, sample integrity, representative good, and the sampling system error is little, can be widely used in the various Belt Type Coal Conveying Systems and take coal sample.
Below in conjunction with accompanying drawing this utility model is described further.
Accompanying drawing is a structural representation of the present utility model, wherein: 1-power push-rod 2-coupling arrangement 3-lever 4-sampling baffle 5-thief hatch 6-hopper
Sampling baffle 4 is a garden arcuation steel plate, its central authorities open the thieff hatch of one 300 * 500mm, sampling baffle and lever 2 are fixedly connected, power push-rod 1 promotes the lever to-and-fro movement by coupling mechanism 2, and lever 3 drive sampling baffles 4 are done the cutting coal and flowed to reciprocating cutter in coal stream, and the maximum reciprocating stroke of thieff hatch is 600mm, when thieff hatch 5 enters coal stream, a small gangs of coal stream is gone out from thieff hatch, falls into hopper 6, as coal sample.
