Further: described water supply container be shaped as cylinder.
Further: described seal cover is provided with external screw thread, described water inlet is provided with internal thread, and described seal cover is tightened on described water inlet.
Compared with prior art, technique effect of the present utility model comprises:
1, the realization of negative pressure completes by pressure regulation, overcome and originally necessarily required the restriction of source of irrigation water less than or equal to irrigator elevation, Negative pressure irrigation is more easily implemented, maximum feature is exactly to utilize the suction of soil and root system, automatically regulate the water yield of water irrigating hole on water delivery hollow billet, both crop needs had been met, do not cause again the waste of water and excessively wet soil environment, water, fertilizer, gas, the heat of root region soil are remained on preferably under state, for promoting crop growth and coordinating on crop field and the dispensed materials of under ground portion all has significant impact;
2, the flexible adjustment of negative pressure is convenient, can regulate the conditions of demand of water in various seasons according to crop, to meet the water demand of crop, has saved equipment investment, has saved the energy;
3, Negative pressure irrigation is the local infiltrating irrigation of point source of moistening local crop root zone, has avoided the deep percolation in the soil evaporation He Gen district of crop break, has improved the validity of irrigation water, has improved largely the utilization ratio of water resource;
4 these irrigation systems are simple in structure, and use and management and maintenance are convenient, save labour, simultaneously can fertilizer is water-soluble, carry out manuring irrigation, and improve the utilization ratio of fertilizer, the pollution of minimizing to soil and groundwater;
5, this irrigation method and system are particularly suitable for the area of drought and water shortage, to orchard and greenhouse by solar heat, booth vegetable better effects if.
Brief description of the drawings
Fig. 1 is the use state diagram of the underground negative pressure seepage filling device of adjustable-pressure in the utility model.
Embodiment
Below with reference to accompanying drawing and preferred embodiment, technical solutions of the utility model are elaborated.
As shown in the figure, the use state diagram of the underground negative pressure seepage filling device of adjustable-pressure in the utility model.
The structure of the underground negative pressure seepage filling device of adjustable-pressure comprises: water irrigating hole 1, water delivery hollow billet 2, gauge tap 3, delivery port 4, water supply container 5, seal cover 6, water inlet 7, surge pipe 8, surge pipe through hole 9, sealing ring 10 and unidirectional air exhaust nozzle 11; Water supply container 5 is a closed container being filled with water, and its top has water inlet 7 and surge pipe through hole 9; Seal cover 6 is arranged on water inlet 7, and water inlet 7 is for injected water, and seal cover 6 is for airtight water inlet 7; On surge pipe through hole 9, be provided with sealing ring 10, surge pipe 8 is through surge pipe through hole 9 and sealing ring 10, surge pipe 8 both ends opens; The material of sealing ring 10 is rubber, and sealing ring 10, in sealing surge pipe 8, can also make to seal surge pipe 8 and slide up and down in sealing ring 10; Water supply container 9 is provided with delivery port 4 in the bottom of sidewall, is provided with gauge tap 3 on delivery port 4; An end of water delivery hollow billet 2 is airtight, and another is open-ended, has multiple water irrigating holes 1 on the sidewall of water delivery hollow billet 2; The opening of water delivery hollow billet 2 is connected on delivery port 4; Unidirectional air exhaust nozzle 11 is arranged on top or the top of water supply container 9, on unidirectional air exhaust nozzle 11, is connected with air exhauster.
Water supply container 5 can be various shapes, in the utility model, water supply container 5 be shaped as cylinder.Certainly, seal cover 6 can arrange external screw thread, and water inlet 7 arranges internal thread, and seal cover 6 is tightened on water inlet 7; In the utility model, the material of seal cover 6 is rubber, utilizes the elasticity of rubber, and seal cover 6 directly covers on water inlet 7.Water irrigating hole 1 can also connect delivery pipe branch, is beneficial to irrigate.
