Background technology
Since last century the nineties, in the northern area of China, sandstorm weather odds is more and more frequent, and soil drifting problem is also more and more serious, and aeolian transport and control have become the key subjects of China's Environmental Studies.In order to effectively defend and control sand, prevent soil drifting from endangering, need the wind erosion carrying out field or wind-tunnel to measure, accurately understanding and grasp Mechanism of Wind Blow Sand Movement.Sand-taped instrument is research dust storm movement law, and one of important kind of measurement instrument of observation near surface Structure of wind-Sand Flow feature, the most important index evaluating sand-taped instrument performance is exactly trap efficiency.In recent ten years, about the research of the husky performance of collection, also just experimental study mostly, complicated and changeable due to test condition, to sand-taped instrument of the same race, the result that different tests person draws also varies, and therefore, the structure for dust storm instrument needs to optimize further.
Summary of the invention
The purpose of this utility model is that proposing one can rotate with the wind, various dust storm particle is relied on natural wind to carry out sieving, the sand-taped instrument of sample grading.
The purpose of this utility model is achieved in that wind direction rotation type hierarchical layered particle sand-taped instrument, comprise air port guide plate, hold-down support, open and close type drum and classification silt container, described open and close type drum be up and down all close, the openable cavity body in side, described air port guide plate keeps vertical with open and close type drum side and is fixedly connected with, described open and close type drum is located on hold-down support by rotating shaft, the inner stationary shaft being also provided with setting from end face to bottom surface of described open and close type drum; Described classification silt container is the closed box with sand inlet, and described classification silt container is located on stationary shaft in interval by mounting base from top to bottom, and described sand inlet towards the opposite side of described air port guide plate fixation side, and stretches out outside open and close type drum.
Further, from outside to inside separating with the dividing plate that some height reduce gradually in described classification silt container, form the collection Sand Bucket that several are separated, the top of collection Sand Bucket is provided with sieve, and the sieve of Neighbor Set Sand Bucket head and the tail connect successively, ascending from the sieve aperture of outside to inside sieve.
Further, infundibulate cloth bag is provided with below described sieve.
Further, any described sieve is provided with flexure strip, and sieve overhung has windmill, and described windmill when rotated its blade is stirred flexure strip.
Wind direction rotation type hierarchical layered particle sand-taped instrument structure of the present utility model is simple, the physical motion of ingenious utilization dust storm particle and flowing law, can realize rotating with the wind, can adjust particle collection position according to actual conditions, be particularly suitable for differing heights in wind tunnel test and gather particle; Particle can also be carried out classification collection, for the research of field wind-driven sediment particle and sampling provide foundation.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the one-piece construction schematic diagram of sand-taped instrument;
Fig. 2 is the structural representation of silt container.
Legend: 1. air port guide plate, 2. rotating shaft, 3. stationary shaft, 4. open and close type drum, 5. classification silt container, 6. hold-down support, 51. silt container mounting bases, 52. windmills, 53. flexure strips, 54. sand inlets, 55. one-level sieves, 56. cloth bags, 57. dividing plates, 58. secondary sieves.
Embodiment: the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1-2, wind direction rotation type hierarchical layered particle sand-taped instrument, comprise air port guide plate 1, hold-down support 6, open and close type drum 4 and classification silt container 5, open and close type drum 4 be up and down all close, the openable cavity body in side, air port guide plate 1 is fixedly connected with open and close type drum 4 side, open and close type drum 4 is located on hold-down support 6 by rotating shaft 2, and open and close type drum 4 inside is also provided with the stationary shaft 3 of setting from end face to bottom surface; Classification silt container 5 is for having the closed box of sand inlet 54, and classification silt container 5 is fixed on stationary shaft 3 in interval by mounting base 51 from top to bottom, sand inlet 54 towards air port guide plate 1 fixation side opposite side and stretch out outside open and close type drum 4.
During use, sand-taped instrument is placed in the environment needing to study dust storm movement law, when calm in environment, sand-taped instrument transfixion, is in equilibrium state; When there being wind in environment, because air port guide plate 1 is subject to the thrust of wind, open and close type drum 4 is impelled 2 to rotate around the shaft, classification silt container 5 also rotates with open and close type drum 4 and rotates, until turn to air port guide plate 1 parallel with wind direction time reach balance, make sand inlet 54 all the time towards the direction that wind comes, be conducive to collecting dust storm.After collection work terminates, only need open open and close type drum 4 from the side, classification silt container 5 is taken off from stationary shaft 3.
Classification silt container 5 is arranged at interval from top to bottom along stationary shaft 3, and the needs according to research can set the height of open and close type drum 4, the number of classification silt container 5 or interval, flexibly to adapt to the dust storm particle collection of differing heights.
In order to experimental study dust storm being carried out to grain size screening or classification of satisfying the demand, separate from the dividing plate 57 outside to inside reduced gradually with some height in classification silt container 5, form the collection Sand Bucket that several are separated, the top of collection Sand Bucket is provided with sieve 55,58, and the sieve 55,58 of Neighbor Set Sand Bucket head and the tail connect successively, ascending from the sieve aperture of outside to inside sieve 55,58; In order to better collect the dust storm fallen from sieve 55,58 top sieve, preventing dust storm from overflowing in collection Sand Bucket and fly or scurry out, below sieve 55,58, being provided with infundibulate cloth bag 56.In the present embodiment, be provided with two-stage collection Sand Bucket altogether, corresponding one-level sieve 55 and secondary sieve 58.Can according to practical study needs, the setting collection number of Sand Bucket and the progression of sieve flexibly.
In order to better utilize natural wind to obtain better gradation effect, one-level sieve 55 is provided with flexure strip 53, and one-level sieve 55 overhung has windmill 52, and windmill 52 when rotated its blade is stirred flexure strip 53.When dust storm blows in classification silt container 5 from sand inlet 54 under the effect of extraneous wind-force, remaining wind-force makes windmill 52 rotate, windmill 52 is in rotary course, its blade is stirred flexure strip 53 at regular intervals, one-level sieve 55 produces vibration under the disturbance of flexure strip 53, secondary sieve 58 is also vibrated with one-level sieve 55, improves efficiency and the effect of dust storm particle screening.
Above technical characteristic is only embodiment of the present utility model, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
