Description

The self-priming well
Technical field
The present invention relates to a kind of self-priming well, belong to the agricultural production equipment technical field.
Background technology
Underground water (ground water) is present in the water in crustal rock crack or the interstices of soil.The difference of mode of occurence under the base area, underground water can be divided into perched water, diving and artesian water three major types.Perched water is because local impermeable role, makes down the atmospheric precipitation of oozing rest on formed water-accumulating body in rock fracture or the illuvial horizon of shallow-layer.Diving is the underground water that buries on first stable water barrier below the face of land, and seen underground water is diving mostly usually., diving just forms spring when flowing out ground.Artesian water be bury darker, flow in two underground water between the water barrier.This underground water often has bigger water pressure, and particularly when two water barriers were skewed up and down, the water body in the interlayer will bear bigger water pressure.When the upper strata top board was passed in well or boring, powerful pressure will make water body gush, and formed artesian water.
The space of capillary water in ground communicates with each other between the space less than 1 millimeter, as capillary, when these small spaces are stored aqueous water, just forms capillary water.If capillary water rises up from groundwater level, be called anastatic water; If it doesn't matter with groundwater level, the water source infiltrates and the capillary water of formation from ground, is called hanging capillary water.Capillary water receives the effect of gravity and the hydrostatic pressure of bearing, and its moisture is continuous, and can join saturated zone and aeration zone.Capillary water can transmit hydrostatic pressure, and can be absorbed by root system of plant.
What folks of china was commonly used for a long time is the circular cylinder well.The people can directly be lowered to and excavate native stone in the pit shaft when mostly diameter was that 1～2 meter ﹐ degree of depth is generally several meters to 20～30 meters ﹐ construction.This well only is suitable for the exploitation phreatic water.In the agricultural production district that does not have the river, lake, the water that people are a farmer to be needed all is to draw from the well the inside.Well why can water outlet, is because there is a rainwash layer on the face of land, in this one deck, water is arranged.When there was the space in runoff layer somewhere, the face of land, water will be concentrated to the space, and along with moisture is siphoned away, water on every side will flow to this place continually, and to replenish the water of this place's disappearance, this also is the reason that well can be supplied people's water continually.Along with the variation of rainwash water level, water level is also along with variation in the well.
In agricultural production, generally be to utilize water pump to draw from the water intaking of well the inside, this mode can make the crops obtain water supply in the short time; But exist huge waste; Quite most water pouring back to deep layer, has been returned the rainwash layer along soil permeability again, and the moisture that the crops really obtains is limited; After a while, the crops root still can lack of water.So the peasant often will water repeatedly in the season of growth in the crops, generally to water three time water from the beginning of spring to grouting such as the winter wheat of North China Plain plantation, improved peasant's planting cost greatly.How to let the crops promptly obtain water and not too waste a great difficult problem that becomes the raising farmers' income again? So greatly develop today of high-efficiency agriculture in China; Inventing a kind ofly has the water supply when needing water in the crops, and needing how much water is necessary from the self-priming well of how much water of kinetic energy supply just.
Summary of the invention
In order to overcome the huge waste that existing pouring mode causes, improve the farmland efficiency of water application, reduce the difficult problem of peasants'production cost; The invention provides a kind of self-priming well, this self-priming well utilizes capillary theory, designs a kind of equipment; The pulling force that produces with evaporation from topsoil and plant transpiration effect is a power; Water is drunk up in the rainwash layer, arrive the root in crops, to satisfy the required moisture of crops growth automatically.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of self-priming well, described self-priming well is made up of double-layer plastic film, well body, well body suction head, cover, capillary core, thin water guide core, thick water guide core, bundle of capillary tubes, the cover chamber of pouring water, relay water storage sheet, tank; The lower end of well body is provided with well body suction head, and is arranged in the water layer, and the upper end of well body is provided with double-layer plastic film, and the well body is provided with relay water storage sheet, and described relay water storage sheet is provided with capillary jack and aqua storage tank; Described double-layer plastic film is arranged in the native layer of sand, and the inner chamber of double-layer plastic film is connected with tank, and double-layer plastic film is circular; Comprise film and following film, the central authorities of last film are provided with the cover of pouring water of a convexity, are the cover chamber of pouring water in the cover of pouring water; Its roof is hemispheric sclerine, pour water the cover chamber airtight be fixed on the well body directly over, the edge of last film is last fenestra district; It is a ring-band shape, in last fenestra district, is provided with aperture, and the middle part of last film is last film water guide district; Following film is provided with the hole that the well body passes in the center; Hole peripheral is connected with the well body is airtight, is provided with capillary core, thin water guide core and thick water guide core between the last film of double-layer plastic film and the following film, bundle of capillary tubes and relay water storage sheet in the capillary core connected well body.
Described double-layer plastic film is embedded in the native layer of sand, and the degree of depth is 10-20 centimetre.
Described well body slightly is 10-20 centimetre, long 20-30 rice glass tube.
Described capillary is the reclinate glass tubule of an end; Be made up of capillary straight sections and capillary bent portion, internal diameter is the 0.9-1 millimeter, and wall thickness is the 0.10-0.15 millimeter; Capillary straight sections pipe range is the 20-25 millimeter, and capillary bent portion pipe range is the 3-5 millimeter.
The described aperture that is provided with in the fenestra district of going up, the aperture is 1 millimeter.
The capillary of described relay water storage sheet constitutes bundle of capillary tubes.
Described well body is every to be provided with relay water storage sheet at a distance from 2-2.5 centimetre.
Beneficial effect of the present invention does; The self-priming well utilizes a kind of agricultural production equipment of capillary theory design, and the pulling force that produces with evaporation from topsoil and plant transpiration effect is a power, and water is drunk up in the rainwash layer; Arrive the root in crops, to satisfy the required moisture of crops growth automatically.Can overcome the huge waste that existing pouring mode causes, improve the farmland efficiency of water application, reduce the difficult problem of peasants'production cost.
