According to current specifications requirement, all need before dam material fills to carry out grain composition detection to it, need after placement grinding again to carry out grain composition detection.In Hydraulic and Hydro-Power Engineering, the grain composition of dam material is detected and all adopt sieve formula, cardinal principle is be placed in by screening materials carrying in screen set that size of mesh size successively decreases successively, after sieving certain hour successively, material is stayed on each layer sieve by the size of particle respectively, be divided into some levels, calculate the percentage that triage weight at different levels accounts for general assembly (TW) successively, and calculate the grain composition of screening material thing.
The dam material material source quality control of current earth and rockfill dam comprises grating and detects, and in specification, regulation compaction quality detects also is cheat inspection method for master, and it is essential that grating detects, and other lossless detection methods are only as auxiliary detection means.Hole inspection method master operation is: screening material is chosen, manual grading skill screening, data record, data analysis, provide test report.The method can realize the object that dam material grain composition detects, but sieving time is longer, sieving technology is complicated, and every operation is manual operation, consumes a large amount of labour.Dam, long river hydroelectric station dam is the amount of filling about 3,400 ten thousand m always
3, its dam material grain composition detects frequent, and this project is mainly filled and expected that the sampling frequency is as follows: filter material 1 time/200m
3~ 500m
3; Transition Materials 1 time/500m
3~ 1000m
3; Stockpile 1 time/10000m
3~ 100000m
3, particularly stockpile, single group material sample volume is large, adopts conventional artificial sieve formula workload large, and because dam material is sized to, to provide the test report time longer simultaneously, restriction dam embankment construction in various degree.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of dam material grating pick-up unit, solve conventional artificial sieve formula workload large, the problems such as it is longer to provide the test report time, the construction of restriction dam embankment, and then improve effective engineering time, save labour, reduce construction cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of dam material grating pick-up unit, comprise the support bar for supporting whole pick-up unit, side direction baffle plate, screen cloth and vibrations separating plate, described side direction baffle plate forms a square box, screen cloth is provided with in described square box, described screen cloth has certain angle of inclination and the sieve aperture of screen cloth is increasing from high to low, the sieve aperture that size is identical forms a region, vibrations separating plate is provided with between regional, all cage of weighing is provided with below each region, described vibrations separating plate and screen cloth are provided with the electromagnetic shaker driving its vibrations, the square box that side direction baffle plate is formed is arranged on support bar.
Further, described support bar is also fixed with vibroshock.
Further, described support bar is fixed on flat base, is provided with wheel below described flat base, described flat base is also provided with the fixed bar avoiding described dam material grating pick-up unit to slide.
Further, the angle of inclination of described screen cloth is 10 °.
Compared with prior art, the beneficial effects of the utility model are: achieve the mechanization degree that dam material grating detects, by avoiding manual operation because usually improving testing inspection precision.Meanwhile, improve the operating efficiency that grating detects, shorten detection time, improve construction speed, package unit has high operability.
