Background technology:
At present, soil drifting has become the main inducing of China's arid and semi-arid area land deterioration, explore wind erosion process mechanism and relative influence mechanism thereof, for research near surface, sandstorm has very important significance and is worth, further explore and slow down desertification of land, understand the rule of development and the extent of injury of sandstorm, and further administer the basis of sandstorm.Soil drifting refers to taking wind-force as main external agency and acts on the erosion process that ground causes that sand stirs up a cloud of dust, jumps and rolls.The process that soil drifting is carried and piled up the soil on earth's surface, particulate in soil with the wind drift can form sandstorm, have a strong impact on the quality of air environment of wide geographic area, especially the communications and transportation to city, leeward district, people's lives daily life bring very adverse influence, can cause the farmland soil erosion in sand and dust source region simultaneously, soil productivity declines, the increasing the weight of of desertification phenomenon.The method of traditional measurement wind erosion quantity is to use sand-taped instrument, under natural wind deflation, surface soil is carried out to the measurement of wind erosion quantity, or matched and made for completing the measurement to wind erosion quantity by wind-tunnel and sand-taped instrument, but sand-taped instrument can not accurately be distinguished for specific experiment demand the quantitative variation characteristic of the forward and backward soil of wind erosion.In addition, be used in conjunction with wind-tunnel and sand-taped instrument cost is large, be difficult for installing, construction inconvenience.
Utility model content:
The utility model provides a kind of soil drifting feature field survey device, it is simple in structure, easy to use, can complete the wind erosion quantity of the various specific pedotheques in field is measured, measure accurately the quantitative variation of the forward and backward soil of wind erosion, and be not subject to the restriction of landform, be easy to install, convenient construction, applicability is strong, cost is low, has solved problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of soil drifting feature field survey device, comprise a support bar of vertical setting, the top of support bar is connected with the lower surface middle part of a horizontally disposed base, the movable disk body that clamps an opening upwards setting on base, and the bottom of support bar is back taper setting.
Described base comprises a horizontally disposed square floor, and lower surface middle part and the top of support bar of square floor are connected, and are respectively equipped with a baffle plate vertically arranging in each side of square floor.
Outer surface at each baffle plate is installed with respectively several springs, is respectively equipped with a hook in the outer end of each spring.
Be provided with an auxiliary fixing feet in support bar bottom one side, described auxiliary fixing feet comprises the cross bar and the montant that are connected, and cross bar and support bar bottom one side are connected, and montant and support bar be arranged in parallel, the bottom of montant bottom and support bar flushes, and the bottom of montant is back taper setting.
The length of described montant is 25cm, and the length of the support bar of cross bar upside is 100cm.
The utility model adopts such scheme, simple in structure, easy to use, can complete the wind erosion quantity of the various specific pedotheques in field is measured, distinguish accurately the quantitative variation of the forward and backward soil of wind erosion, and be not subject to the restriction of landform, be easy to install, convenient construction, applicability is strong, and cost is low.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model support bar and base.
Fig. 3 is the local structure for amplifying schematic diagram of A portion.
In figure, 1, support bar; 2, disk body; 3, square floor; 4, baffle plate; 5, spring; 6, hook; 7, cross bar; 8, montant.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-3, a kind of soil drifting feature field survey device, comprises a support bar 1 of vertical setting, and the top of support bar 1 is connected with the lower surface middle part of a horizontally disposed base, the movable disk body 2 that clamps an opening upwards setting on base, the bottom of support bar 1 is back taper setting.
Described base comprises a horizontally disposed square floor 3, and lower surface middle part and the top of support bar 1 of square floor 3 are connected, and are respectively equipped with a baffle plate 4 vertically arranging in each side of square floor 3.
Be installed with respectively several springs 5 at the outer surface of each baffle plate 4, be respectively equipped with a hook 6 in the outer end of each spring 5.Elongate spring 5 by hook 6 disk body 2 top side wall that hang on base, under the pulling force effect of spring 5, disk body 2 can be fixed on base, greatly increase stability, effectively prevent wind-force become large after, by the blow off generation of phenomenon of disk body 2.
Be provided with an auxiliary fixing feet in support bar 1 bottom one side, described auxiliary fixing feet comprises the cross bar 7 and the montant 8 that are connected, and cross bar 7 is connected with support bar 1 bottom one side, and montant 8 be arranged in parallel with support bar 1, the bottom of montant 8 bottoms and support bar 1 flushes, and the bottom of montant 8 is back taper setting.
The length of described montant is 25cm, and the length of the support bar of cross bar upside is 100cm.
When use, the bottom of support bar 1 back taper and auxiliary fixing feet are vertically inserted in the soil in field simultaneously, make base and the ground maintenance level on support bar 1 top, be not subject to the restriction of extraneous topographic condition, especially on the ground uneven, physical features is precipitous, also can conveniently fix disk body 2, applicability is strong, in the time that the montant of auxiliary support bar extend into below ground completely, can better fix stationary installation.Then the specific soil of needs being measured is put on disk body 2, after it is weighed, record data M1, then, disk body 2 is connected between each baffle plate 4 on square floor 3, so that fixing disk body 2, in the process of placing, wind can outwards blow out the soil on disk body 2 from 2 air ports of disk body, and be scattering on ground, can effectively prevent that wind from blowing to ground sand and dust in disk body 2, greatly reduce the impact on measurement data, improve the degree of accuracy of data.Through after a period of time, disk body 2 is taken out from base, measure the now weight of disk body 2, record data M2, the data M2 of twice weighing deducts M1, is wind erosion quantity, can help scientific research personnel accurately to distinguish the quantitative variation characteristic of the forward and backward soil of wind erosion for specific experiment demand.In addition, scientific research personnel can use organizing stationary installation more simultaneously, can complete the wind erosion quantity of the various specific pedotheques in field is measured, various specific soil will be put into respectively in the disk body of each stationary installation, applicability is strong, can greatly raise the efficiency, without carrying out the measurement of wind erosion quantity for a kind of soil in field, greatly improve work efficiency.Scientific research personnel, by the contrast of data, can help scientific research personnel to carry out correlative study, to further exploration with slow down desertification of land, understands the rule of development and the extent of injury of sandstorm, and further administers sandstorm, significant.
Above-mentioned embodiment can not be served as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification that the utility model embodiment is made or conversion all drop in protection domain of the present utility model.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
