Embodiment
Further specify the utility model below in conjunction with Figure of description.
As described in Figure, a kind of rice field special-purpose soil percolate extraction element comprises soil filtration liquid collection tube 1, solution receiving flask 4, surge flask 5 and vacuum pump 6.Soil filtration liquid collection tube 1 is made of pot clay end 7 and body 8, and its middle tube body 8 is made by PVC or rigid plastic.The length of soil filtration liquid collection tube 1 is for gathering the exposed length sum in the soil filtration liquid degree of depth and field, and the exposed length in field is 20~40cm.On soil filtration liquid collection tube 1 port collection tube rubber plug 9 is set, is inserted with steam hose 3 and first delivery hose 2 on the collection tube rubber plug 9, wherein first delivery hose 2 stretches into soil filtration liquid collection tube 1 bottom.First delivery hose, 2 other ends insert in the solution receiving flask 4 by the receiving flask rubber plug 10 that arranges, and soil filtration liquid collection tube 1 and solution receiving flask 4 are communicated.Also be inserted with second delivery hose 12 on the receiving flask rubber plug 10.Second delivery hose, 12 other ends insert in the surge flask 5 by the surge flask rubber plug 11 that arranges, and solution receiving flask 4 and surge flask 5 are communicated.Also be inserted with exhaust tube 13 on the surge flask rubber plug 11, exhaust tube 13 is connected with vacuum pump 6.Vacuum pump 6 is adjustable negative-pressure vacuum pump, and it can take out negative pressure.
In order to guarantee leakproofness, evenly smear fluid sealant at the rubber plug of soil filtration liquid collection tube 1, solution receiving flask 4, surge flask 5 and the junction of flexible pipe.
