What both ends were parallel to each other afterwards is horizontally arranged with two support beams being made up of angle steel, and the top of two support beams is along support
The upright guide edge of beam length direction extension, the rear and front end of described section of rain groove are provided with directive wheel, described section of rain groove
The directive wheel of rear and front end is respectively placed on the guide edge of front and rear two support beams, is provided with the guide edge for limiting
Make the limiting card of the directive wheel movement.
The limiting card includes the clip main body that cross section is n fonts, and a side wall of the clip main body is provided with logical
Hole, the side wall of the clip main body are provided with nut on the outside of the through hole, and a bolt, which is worn, is connected to the nut
And in the through hole.
Described section of rain groove include two be parallel to each other made of angle steel girder, along the length direction of girder pass through bolt
Uniformly it is connected to multiple V-arrangement brace rods between two girders and is placed in the groove that two girders are formed with these V-arrangement brace rods
Cross section be V-shaped transparent plastic sheet, the rear and front end of two girders is respectively connected with end plate, and each end plate is equal
It is connected by mandrel with the directive wheel.
It is described subtract the angle steel that rain frame is set by more transverse direction and longitudinal directions and be bolted form.
The beneficial effects of the utility model are：The utility model is rational in infrastructure, is easy to dismount, and is easy to transport, can easily be accommodated
The spacing of adjacent section of rain groove, it is practical, it is to study the ideal device that Grassland ecosystems change under drought condition.

Embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
As shown in Fig. 2 a kind of subtract rain device for field ecological experiment, including rear end is high, front end is low subtract rain frame 1 and
Be connected to multiple inclined V-types for subtracting on rain frame 1 cuts rain groove 4, and subtract that the rear and front end of rain frame 1 is parallel to each other is horizontally arranged with
Two support beams 2 being made up of angle steel, the top of two support beams 2 are the upright guiding extended along the length direction of support beam 2
Side 3, the rear and front end for cutting rain groove 4 are provided with directive wheel 9, and the directive wheel 9 for cutting the rear and front end of rain groove 4 is respectively placed in front and rear two
On the guide edge 3 of root support beam 2, the limiting card 10 moved for restricted guidance wheel 9 is provided with guide edge 3.
As shown in figure 4, limiting card 10 includes the clip main body 11 that cross section is n fonts, a side wall of clip main body 11
Through hole is provided with, the side wall of clip main body 11 is provided with nut 12 on the outside of through hole, and a bolt 14 wears and is connected to spiral shell
