Abstract
The utility model relates to an automatic sampling device, which comprises a hydraulic cylinder, a telescopic rod, a coal scraping plate, a dustproof cover and a sampling groove. A piston of the hydraulic cylinder is connected with the telescopic rod, the front end of the telescopic rod is connected with the sampling groove, the dustproof cover is arranged below the hydraulic cylinder and fixed on an isolation wall, the other side of the isolation wall is provided with a crusher, the coal scraping plate is fixed inside the dustproof cover and located on the inner side of the sampling groove, and the lower end of the dustproof cover is provided with a sample discharge opening. The automatic sampling device is reasonable in structural design and convenient in operation, effectively reduces labor intensity of operators, and increases sampling safety factors.
Description
Technical field
The utility model relates to a kind of sampling instrument, particularly relates to a kind of automatic sampling device that is used for coal.
Background technology
Former coking industry mixed coal sampling is adopted manually from belt intercepting linear flow coal sample, owing to cooperate coal charge on belt, to form taper during the comminutor blanking, during hand sampling, can only get the top coal sample, cause the result of laboratory test of the coal sample of getting not possess representativeness, and manually can't take a sample every comminutor, can not react the coal blending index of every comminutor, and, in the artificial sample process, there is bigger potential safety hazard because the belt running speed is bigger.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, the automatic sampling device that is used for coal easy to use.
In order to address the above problem, the utility model by the following technical solutions:
A kind of automatic sampling device, comprise hydraulic cylinder, expansion link, coal scraper plate, dust cover and sampling groove, hydraulic cylinder piston is connected with expansion link, the expansion link front end is connected with sampling groove, and the hydraulic cylinder below is provided with dust cover, and dust cover is fixed on the divider wall, the divider wall opposite side is provided with comminutor, dust cover internal fixation coal scraper plate, coal scraper plate is positioned at the sampling groove inboard, and the dust cover lower end is following sample mouth.
Compared with prior art, the beneficial effects of the utility model are:
1, drive the expansion link action by hydraulic cylinder, realize the sampling groove timing sampling, sampling has evenly effectively improved the accuracy of result of laboratory test.
2, the utility model has been realized automatic sampled functions, has avoided hand sampling to the danger that operating personnel bring, and effectively raises the sampling safety coefficient.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sampling groove schematic cross-section.
Embodiment
A kind of automatic sampling device, as shown in Figure 1, comprise hydraulic cylinder 1, expansion link 2, coal scraper plate 5, dust cover 3 and sampling groove 4, hydraulic cylinder 1 piston is connected with expansion link 2, expansion link 2 front ends are connected with sampling groove 4, hydraulic cylinder 1 below is provided with dust cover 3, dust cover 3 is fixed on the divider wall 7, divider wall 7 opposite sides are provided with comminutor 9, dust cover 3 internal fixation coal scraper plates 5, as shown in Figure 2, coal scraper plate 5 is positioned at sampling groove 4 inboards, be provided with hole with sampling groove 4 corresponding positions on the divider wall 7, dust cover 3 lower ends are following sample mouth 6.
During sampling, hydraulic cylinder 1 is by 4 actions of expansion link 2 motion sampling grooves, sampling groove 4 reaches disintegrating machine feed opening 8 belows by the hole on the divider wall 7, the material sample falls in the sampling groove 4, sampling groove 4 is the picture swivel motion under the drive of expansion link 2, coal scraper plate 5 is scraped the material toggling sample, makes the material sample flow out from the following sample mouth 6 of dust cover 3 lower ends, send laboratory assay.
