Abstract
The utility model relates to a low water head self-flow underground infiltrating irrigation device, adopting an underground pipeline. The utility model is mainly composed of an accumulator and a capillary tube which is communicated with the accumulator. The water inflow point of the capillary tube is provided with a filter screen and a valve gate. The capillary tube is buried underground. One end of the capillary tube, which is closed to the accumulator is provided with an upright transparent sight tube which is communicated with the capillary tube and is above the accumulator water level. The far end of the capillary tube tilt up, and the far end of the capillary tube is provided with a deflation valve. The capillary tube is a thin-wall tube whose wall thickness is 0.7-1 mm. A plurality of water penetration holes whose hole diameters are 0.5-1 mm are arranged on the capillary tube body. The summation of the cross sectional area in the water penetration holes is the 70%-80% of the cross sectional area in the capillary tube. The utility model is water saving, electricity saving, labor saving, money saving, and energy saving. The utility model has high efficiency, without blockage. The utility model can make the crops greatly increase in yield.
Description
The utility model belongs to irrigation rig under the agricultural land, relates to a kind of low water head self-flow pattern sub-irrigation device.
The agricultural subsurface irrigation has been studied for many years both at home and abroad, irritates to the domestic pipe once promoted from external drip irrigation, and the multiple boring method on pipe studied of someone in recent years.But present subsurface irrigation method or broad irrigation can not be economized on water, or can not reach the purpose of irrigation because of obstruction.The influence that utilizes pump to fetch water also to be subjected to the rural area to have a power failure delays farming season.What have does not then conform in national conditions because of system complex involves great expense.
The purpose of this utility model is to provide a kind of low water head self-flow pattern sub-irrigation device, adopts underground piping.It mainly is made up of an accumulator and the hollow billet that communicates with it, filter screen and valve are equipped with in water inlet place of hollow billet, hollow billet is embedded in underground, it is equipped with one near accumulator one end place and communicates with hollow billet and to be higher than the upright transparent air inlet observation tube of accumulator water level, the hollow billet far-end upwarps and is not less than ground, the flushing vent valve is equipped with in the end, hollow billet is the light-wall pipe of wall thickness 0.7-1 millimeter, have the infiltration hole of a plurality of apertures 0.5-1 millimeter on the pipe shaft, the interior sectional area summation in all infiltration holes is the 70-80% of sectional area in the hollow billet.
When the utility model used, water entered hollow billet after clarifying and filtering in accumulator, penetrated incessantly from the infiltration hole, stopped up in the hollow billet to avoid foreign material such as outside soil and root system in the small pressure area that forms on every side in hole.Can observe streamflow regime in the understanding hollow billet by the air inlet observation tube.Utilize air inlet observation tube and flushing vent valve can be used for hollow billet is cleaned, also can in soil, cure by oxygen therapy naturally, be beneficial to crop growth.This device, also can be sent into chemical fertilizer in the soil by hollow billet more than 60% than general irrigation method water saving, and 0.07 hectare only need be thrown 200-300 unit, can reach high and stable yields.Through long-time on probation, do not stop up, clean also very convenient.
The utility model is described in further detail below in conjunction with embodiment of the present utility model.
Description of drawings:
Fig. 1-the utility model structure chart,
Fig. 2-hollow billet cross-sectional view,
Fig. 3-arm is laid plane,
Fig. 4-many hollow billet is drawn figure.
(1) accumulator, (2) hollow billet promptly has the pipe in infiltration hole, (3) filter screen, (4) valve, (5) observation tube, (6) infiltration hole, (7) big envelope, i.e. vent valve, (8) are responsible for, (9) arm.
Fig. 1, Fig. 2 have showed an embodiment of the present utility model.Accumulator (1) is flat on the ground.For guaranteeing optimum efficiency, the water level of accumulator (1) is 1-3M.Hollow billet (2) communicates through filter screen (3) and accumulator (1) inside.Valve (4) is drawn and be equipped with to hollow billet (2) in the bottom of accumulator (1).Hollow billet (2) bend into downwards in the soil and extends to horizontal direction then, and far-end sticks up ground, and the end is with big envelope (7) as vent valve.Big envelope (7) is pounded flat pipe by an end and is made, and is enclosed within hollow billet (2) end of perk.Observation tube (5) is loaded on the horizontal segment of hollow billet (2) near accumulator (1) one end.Infiltration hole (6) spaced set on the hollow billet (2) has 3 mutual alignments and becomes 120 ° infiltration hole (6) on same cross section.Present embodiment is selected external diameter 20mm for use, and the plastic tube of wall thickness 1mm is as hollow billet (2).The aperture in infiltration hole (6) is 1mm.
As embodiment two of the present utility model, according to the needs of landform and crops, can draw the person in charge (8) and arm (9) as aqueduct from accumulator (1), do not open the infiltration hole on it.Hollow billet (2) is drawn from being responsible for (8) and arm (9).
As embodiment three of the present utility model, can directly draw many hollow billets (2) from accumulator (1) simultaneously as required, can be 2,3,4 so that more.Only drawn among Fig. 4 and drawn the situation of 5 hollow billets (2).
As embodiment four of the present utility model, the wall thickness of hollow billet (2) is 0.7 millimeter, and infiltration aperture, hole (6) is 0.5 millimeter, and other is identical with embodiment one.
The experiment proved that the utility model also has economical, saving of labor, characteristics such as energy-conservation, efficient except that water saving.And be not subjected to the restriction of water source distance, size and terrain slope, directly water delivered to crop root, reduced seepage and surface evaporation with pipeline.Can make 1 times of economic crops such as cotton volume increase, apple volume increase 1-1.5 doubly.
