The second pipe 202 connects spray irrigation pipe 207, and drop/nozzle 208 of spray irrigation pipe 207 opens up attached to 209 root of crop Closely, it is assumed that sapling needs weekly trickle irrigation primary, and 120 minutes every time, about 100 liters of each amount of water required, then: adjusting container 4 Drop/leak rate of second weeper 10 of 4 bottom of extent of opening or container, so that water level decreasing to float 1 is earned in container 4 The period that de- third magnet 103 adsorbs is 1 week, the aperture of the first weeper 205 of second pipe 202 is adjusted, by the flow that drips It is adjusted to drop to the second magnet 102 in 120 minutes and adsorb with the 4th magnet 104 to shake off, once a week according to every work sapling, often Water source 500-1000 watts of 300 power of pump that is secondary that 100 liters of water is needed to calculate, using, water supply is 5000 public ls/h, Mei Ge The spray irrigation pipe 207 of two pipelines, 202 water outlet connection contains 100 drop/nozzles 208, i.e., each second pipe 202 every two hours may be used The water outlet supply of 100 saplings is provided, then, the water source pump 300 can irrigate 12x100 seedling x7=8400 sapling circulation and pour, Assuming that the sapling distribution of 210 side of road is 2 rows, 2 meters of spacing in the rows, main conduit 200 is parallel to the laying of road 210, spray irrigation pipe 207 It is parallel to main conduit 200 and road 210 is laid with, then the crop 209 that each water source pump 300 can supply 8400 meters of length recycles Pour, it may be assumed that do not consider pipeline in the case where the resistance of water flow, the trees of the double plantation in unilateral side of 8400 meters long of road 210 Drop/sprinkling irrigation, it is only necessary to alternating current water source pump 300 can be supplied, and the modes such as irrigate than water-tank lorry and save.Since this is practical new Timing automatic valve 400 described in type can be designed to that container 4 is open state, then encounter rainy, rainwater can fall into appearance naturally Device 4, water level, which rises, can extend the next interval time for opening spray irrigation pipe, be air-dried if encountered, the moisture in container 4 is waved Hair accelerates, it is possible to reduce the interval that second pipe 202 supplies water next time, moisture increase and decrease and Soil Surrounding moisture and work in container 4 209 demand nature speed of increasing and decrease of object is consistent, and demand of the opening and closing of second pipe 202 with 209 place soil of crop to moisture is synchronous, It is more in line with the actual demand of water supply.

When pouring crop 209 for the first time, according to the duration that the plan of crop 209 is poured, according to the moisture in the soil of the crop 209 of corresponding position Feelings can realize crop 209 to suitable water is manually injected into the container 4 of each time switch valve 400 at once Self-timing pours.

In special circumstances, as the crop of certain spray irrigation pipe 209 need temporarily to extend certain pouring time interval, then can be with hand Dynamic the first discharging valve 11 for opening corresponding self-timing valve 400, then the water surface rapid increase in container 4, increases evaporation Time then extends the duration that valve 3 opens second pipe 202.

In special circumstances, as the crop of certain spray irrigation pipe 209 need temporarily to extend certain pouring duration, then can beat manually The second discharging valve 12 of corresponding self-timing valve 400 is opened, then the water surface in container 4 quickly reduces, then extends valve 3 and open Open the duration of second pipe 202.

The present apparatus, other than full automatic timing may be implemented and pour, though due on main conduit 200 how many Two pipelines 202 all only open a wherein second pipe 202 simultaneously, therefore not high to water supply power demand, may be implemented common Alternating current alternate power electricity pours, and saves resource and the energy.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
