Abstract
The utility model relates to a raw coal sampling head. Two guiding slide bars are fixed on a bracket which is fixed on a machine frame. Two sliding sleeves which are fixed on an outer wall of a sampling barrel are respectively sheathed on the slide bars. One side of the upper part of the sampling barrel is provided with a storing bucket, and the inner part of the sampling barrel is provided with a spiral sampling bar shaft which is driven by a perpheral motor. A feed tray is arranged at a spiral tail end of the upper part of the spiral sampling bar shaft. A rack bar is arranged on the support, and a gear is connected with the peripheral motor to drive and is engaged with the rack bar to fix on the outer wall of the sampling barrel. The utility model has the advantages of simple structure, easy fabrication, convenient operation, and high reliability for sampling. The utility model is suitable for being used as a substitute of the existing raw coal sampling head.
Description
The utility model is a kind of raw coal sampling head.
Many industrial enterprises, all need use a large amount of coals to make fuel as smeltery, thermal power generation, chemical plant etc., when these fuel enter factory, all be to adopt train or vehicle complete vehicle transportation, factory will carry out coal property test, must take a sample to raw coal, present raw coal sampling machine, be to adopt hydraulic pressure or mechanical drive mode that the sampling head of sampler is pressed in the coal, take a sample, the sampler of this structure, in use there is following problems in proof: 1) sampling head is pressed in the coal, supporting body such as automobile, train are produced immense pressure, might damage its vibration insulating system; 2) employing is pressed into the mode of taking a sample in the coal with sampling head, institute's sample thief only is the sample of top layer coal, it only is certain any sample in the coal seam, and negligible amounts, represent the probability of average properties of coal big inadequately, influence detect data accurately, and this sampling head, need adopt single step of releasing once, the sampling time is long, is difficult to the tippler breath-group coupling with power plant.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and is easy for operation, and sampling depth is adjustable raw coal sampling head arbitrarily.
The utility model is to adopt following proposal to realize: be fixed with two guiding slide bars on a support that is installed on the frame, two sliding sleeves that are installed on the sampling cylinder outer wall are set with on slide bar, sampling cylinder top one side is provided with storing reason bucket, be provided with a spiral thief rod axle by the peripheral hardware drive of motor in the sampling cylinder, end at spiral sampling rod shaft top spiral has been provided with feed table, tooth bar is installed on the support, and gear is connected transmission with the peripheral hardware motor, is installed on the sampling cylinder outer wall with the tooth bar engagement.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing;
Accompanying drawing 1 is the utility model main station portion cut-open view;
Accompanying drawing 2 is the left view of accompanying drawing 1.
See accompanying drawing 1,2, the utility model is by spiral sampling axle 1, sampling cylinder 2, guiding slide bar 3, sliding sleeve 4, tooth bar 5, gear 6, storage bin hopper 7, sluice gate 8, support 9 is formed, described support 9 is installed on the frame, be fixed with two guiding slide bars 3 on it, sliding sleeve 4 is installed on the outer wall of sampling cylinder 2 and is set in guiding slide bar 3, sampling cylinder 2 tops one side is provided with a storage bin hopper 7, be provided with a spiral sampling axle 1 by the peripheral hardware drive of motor in the cylindrical shell, end at spiral sampling axle 1 top spiral is provided with a feed table 10, tooth bar 5 is installed on the support 9, and gear 6 is installed on the outer wall of sampling cylinder 2.
Principle of work of the present utility model is sketched in following: by driven wheel 6,1 rotation of spiral sampling axle respectively of peripheral hardware motor; At this moment, gear 6 rotation and on tooth bar 5, moving, thus drive 1 on spiral sampling axle in sampler barrel and the tube along the tooth bar lengthwise movement, promptly move along tooth bar is upper and lower; When need are sampled, only need to adjust the rotation direction of motor and gear, gear 6 and sampling cylinder 2 are moved downward along tooth bar 5, spiral sampling axle 1 screws in the raw coal, simultaneously, sampling cylinder 2 is also because of the effect of tooth bar 5, gear 6, enter in the raw coal, at this moment, be in raw coal in the sampling cylinder 2 because of the effect of the spiral on the spiral sampling axle 1, move upward along the hand of spiral, until contacting with feed table 10, by feed table 10 coal is sent in the storage bin hopper 7, be provided with two passages at storing mouth place and compile branch, a sample coal part flows back on the car by leading the coal mouth, and another part is collected in storage bin hopper.Thereby need not to adopt a sample and put sample one time, but treat to put again after a car (three samples) has been adopted.The utility model can be taken a sample easily at an arbitrary position owing to adopt said structure, and sampling depth can be regulated arbitrarily, full section sampling, and sampling time and power plant tippler beat coupling, guarantee effectively the quality of sampled product to improve the reliability of raw coal check.
In sum, the utility model is simple in structure, and processing and manufacturing is easy, and is easy to use, and sampling reliability height is suitable for the renewal product as existing raw coal sampling head.
