Abstract
The utility model discloses a kind of controllable soil splash collection devices for holding rain area, include soil box, sputter disk, baffle, retaining wall and the Storage water tank for being mounted on the sputter pan bottom, the Storage water tank is equipped with soil box bayonet, and the soil box is movably connected on the soil box buckle；Sputter disk upper surface is concordant with the section extreme lower position of the soil box.The utility model has the following beneficial effects: structure is simple, and it is easy to operate, precision height is collected to sputter soil particle, has been particularly suitable for gradient sputter, can be used for the splash erosion research of various types soil.
Description
Technical field
The utility model relates to Rainsplash erosion experimental rigs, are mainly used for rainfall sputter soil sample collection.
Background technique
At present in research rainfall erosion research, splash erosion device is mostly opening collection device of the surrounding without retaining wall,
And the naked design in sputter disk upper end, the characteristics of test from sputter, the quality of sputter soil sample is generally smaller, in sputter soil
Sample collection device surrounding, which does not design baffle, will cause the soil sample splashed out to fail to be collected completely, meanwhile, sputter disk upper end is without gear
Plate covers, and raindrop is necessarily caused to carry out secondary sputter to sputter disk, this may cause soil sample that sputter disc portion has been splashed out from
It moves out in sputter disk, the mass loss of the part reduces the sputter quality of soil sample being collected into, and causes shadow to test accuracy
It rings.
Existing sputter device is tested towards to realize to different gradient by adjusting soil box and the whole of sputter disk
It is required that but the change of soil box entirety direction so that holding rain area (projected area of the soil box by raindrop impact surface in the horizontal direction)
It changes, the change for holding rain area necessarily leads to the change for acting on soil box surface layer impact raindrop quantity, this is equivalent to the gradient
Variation simultaneously with holding the change of rain area, variation while causing two factors of rainfall sputter, without being merely the gradient
Single-factor caused by sputter variation.
Utility model content
In view of the deficiencies in the prior art, the utility model is intended to provide a kind of controllable soil splash receipts for holding rain area
Acquisition means, further, the present apparatus solve existing sputter disk surrounding and cause sputter during test without baffle without retaining wall, upper end
The problem of quality of soil sample is lost, and solve to hold rain area with slope change and caused by raindrop impact quantity variation issue；
A kind of semi-enclosed sputter collection device is devised, can will be acted on and the soil for soil box of moving out during sputter by rain insensitive device
Grain is collected to the greatest extent, and has accomplished the change that the gradient is realized in the case where not changing and holding rain area to the design of soil box
Change.
In order to achieve the above object, the utility model proposes technical solution are as follows:
The controllable soil splash collection device for holding rain area, comprising: soil box, sputter disk, baffle, retaining wall and installation
Storage water tank in the sputter pan bottom, the Storage water tank are equipped with soil box bayonet, and the soil box is movably connected on the soil box card
It buckles；Sputter disk upper surface is concordant with the section extreme lower position of the soil box.
It should be noted that the collection device part of sputter soil sample includes that sputter collecting region baffle, retaining wall and sputter are collected
Disk composition, the shutter are set to the top of the retaining wall, and the sputter catch tray is set to the bottom of the retaining wall；It is described to splash
Erosion disk is equipped with the aperture passed through for the soil box；The water inlet is set on the cover board.
It should be further noted that after the soil box passes through the aperture of the sputter catch tray, the aperture periphery
With the gap of 1cm wide between surface and the surface of the soil box.The gap can be such that rainwater flows into Storage water tank.
It should be noted that for there is slope test, this sputter device is provided with region division, divides in Storage water tank equipped with region
Partition has slope soil box slot body to be equipped with region separator bar, and demarcation plate is aligned installation with separator bar, can be by the sputter catch tray equal part
For two regions, i.e., it is divided into upward slope sputter collecting zone and descending sputter collecting zone according to the gradient.
The utility model has the following beneficial effects: structure is simple, and it is easy to operate, precision height is collected to sputter soil particle, especially
It is suitable for there is gradient sputter, it can be used for the splash erosion research of various types soil.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the experiment of the soil box with certain slope.
Specific embodiment
With reference to the accompanying drawing and the utility model is described in detail in specific embodiment, it should be understood that,
The utility model described embodiment is served only for providing a kind of state description, is not used to limit the structure of the utility model.
As shown in Figure 1, the utility model is a kind of controllable soil splash collection device for holding rain area, feature exists
In, including baffle 1, retaining wall 2, sputter disk 3, soil box 4, and be mounted on the Storage water tank 5 of the sputter pan bottom, it is described to be filled with water
Slot 5 is equipped with and installs fixed bayonet for soil box 4,4 upper surface of soil box and is set to sputter disk upper surface positioned at same
Horizontal plane.
It should be noted that the collection device part of sputter soil sample includes that baffle 1, retaining wall 2 and sputter catch tray 3 form,
The baffle 1 is covered on the top of the retaining wall 2, and the sputter catch tray 3 is set to the bottom of the retaining wall 2；The sputter
Catch tray 3 is equipped with the aperture passed through for the soil box 4；The water inlet is set on the cover board 1.
As shown in Fig. 2, being additionally provided with partition 8, the partition 8 is set in the Storage water tank 5, with have slope soil box slot status every
Line 9 be aligned, the sputter catch tray 4 can be divided into two regions, i.e., according to the gradient be divided into upward slope sputter collecting zone 6 and
Descending sputter collecting zone 7.
The sputter disk is equipped with the aperture passed through for the soil box；The water inlet is set on the cover board.
Embodiment
(1) soil sample to be tested is packed into fixed on soil box.It is laid with and sputter catch tray size phase on sputter catch tray
