Description
Technical field
The present invention relates to a kind of mechanical sampling device, relating in particular to a kind of is the portable coal samling machine fast of carrier with the shovel loader.
Background technology
The coal analysis is the element task of Coal Quality monitoring and quality control.The data of having only coal to analyze are accurate, could correctly evaluate Coal Quality and carry out quality control.In coal analyzing total error, the proportion that sampling error accounts for is maximum, and sample variance accounts for 80% of population variance, and sample preparation accounts for 16%, and chemical examination only accounts for 4%.Therefore,, at first from batch coal of being analyzed, take representative sample in order to obtain coal analysis result accurately, then with it bias free be prepared into the analysis sample.For this reason, countries in the world and International Organization for Standardization have all been formulated the method standard of coal samling and sample preparation specially, comprise mechanical sampling and artificial sample method standard.But artificial sample has many shortcomings, and maximum problem is to have personal error.This error is relevant with sample collector's skills involved in the labour, particularly professional ethics; Next is that labour intensity is big; Poor stability; But for the ease of operating, reduce labor intensity, guarantee operator safety, the sampling rules are often formulated fairly simplely again, thereby have reduced sampling precision and brought deviation.
The Coal Mechanical sampling is accurate, quick, labour intensity is low, particularly can avoid personal error.ST (being commonly called as sampling head) is the critical component of mechanical sampling system, and the performance of ST directly influences the objectivity and the fairness of mechanical sampling system.International standard ISO13909 " coal and coke-mechanical sampling method " has strict regulation to the method for sampling and sampling thief performance among standard GB/T19494 " Coal Mechanical sampling " and the GB475-2008 " sample for commercial coal manual pick access method ".Existing static coal samling device exists equipment huge, and is fixed both at home and abroad, and maneuverability is poor, and the difficult variation that adapts to the logistics scene changes, and far can not satisfy coal in China product sampling request.
At present, traditional sample mode is to carry portable Sampling Machine through the workman; Enter in the train railway carriage or automobile bearing box of transportation coal, coal is carried out artificial sample, owing to need repeatedly sample same batch coal; Therefore sample mode efficient is very low, and labor strength is big.
People to develop some coal samling machines, and are used in the actual production in order to address this problem.A kind of automatic sampling machine of jimmy skin is disclosed like Chinese patent document CN88204022U; Comprise sampling spade, walking dolly, undercarriage, door type frame and electric-control system composition, it is provided with column in the rail both sides, and above rail, a door type frame is installed; Make the coal conveyor skin pass through from the door type frame below; Pass through the below undercarriage then, and utilize the sampling spade on the undercarriage that the coal in the coal conveyor skin is taken a sample, thereby obtain the coal sample; The disclosed a kind of coal charge Sampling Machine dolly of Chinese patent document CN200996904Y prevents lifting device for another example; A kind of bridge-type double beam coal charge Sampling Machine is disclosed in its instructions; It adopts the dolly that relies on road wheel to walk along track across the installation on the cart girder of two ends, makes the up-down sampling apparatus walking that is installed on the dolly put in place, then through the up-down sampling apparatus; Coal in the transport vehicle bearing box is taken a sample, thereby obtains the coal sample.
More than two kinds of devices, realized that all mechanization takes the coal sample, but it all need be provided with huge sampling apparatus separately on the direction of conveying arrangement walking, its body is huge, complex structure and overall price are higher, is unfavorable for promoting the use of.
Summary of the invention
