Abstract

The utility model relates to a drip infiltrating pipe which is made of a hard PVC pipe and is characterized in that the drip infiltrating pipe comprises a pipe body which is made of hard PVC materials and is formed by integrally connecting with a water delivering section and a water infiltrating node; the length of water delivering section is equal to the plant spacing of the solanaceous vegetables, and the water infiltrating node is provided with a set of upward pores. The water outlet uniformity of the drip infiltrating pipe is more than or equal to 0.85. The utility model has the advantages of simple structure, convenient use and repair, long service life and low cost, and is the novel and more ideal infiltrating pipe.

Description

A kind of point oozes pipe

Technical field

The point that the utility model belongs in a kind of the placing into the soil oozes pipe, the water-saving irrigation and the environmental protection of the arid and semi-arid area vegetable protecting field that lacks especially for water resource.

Background technology

For scientific and reasonable irrigation, reach water saving, high yield, alleviate the purpose of the soil salinization and crop disease and insect, people invent and have improved many irrigation rigs, as irrigation rigs such as sprinkling irrigation, drip irrigation, little spray drip irrigation and infiltrating irrigations, these devices all have certain limitation in actual application, perhaps cost is too high, and perhaps operation easier is big, is difficult to apply.As spray and to cause that the face of land hardens.Drip irrigation can cause that the table of salinity is poly-, and air humidity is excessive near the soil compaction and the face of land, causes the generation of damage by disease and insect easily.Existing infiltrating irrigation facility, still can not reach as required and supply water, accurately puts the water saving purpose of oozing outside cost is too high except costing an arm and a leg.The producer is difficult to bear, and water-saving irrigation still has sizable potentiality.In order further to excavate this potentiality, reduce raw material and facility cost and the technology that simplifies the operation, need provide a kind of novel infiltrating irrigation pipe to satisfy the demands.

The utility model content

The purpose of this utility model provides a kind of point and oozes pipe, remedies the defective that irrigation rig in the past exists in production practices, and when pouring water, the even moistening infiltrating irrigation pipe surrounding soil of moisture immediately is made for thing and absorbs, and is economical and practical, operability is stronger.

The purpose of this utility model is achieved in that it comprises body, it is characterized in that: the body that adopts hard PVC material to make is connected and composed by water delivery section and infiltration joint integral body, the length of water delivery section equals the spacing in the rows of solanaceous vegetables, has the one group of micropore that is directed upwardly on the infiltration joint.

The utility model has the advantages that on the basis of node type filtration irrigation pipe, the flexible deep water pipe of original socket and plasticity water-supply-pipe are improved to the point that the hard PVC pipe directly is cast with the segmentation micropore ooze pipe, point after the improvement oozes pipe except the advantage that keeps node type filtration irrigation pipe, improved the water outlet uniformity significantly, also reduced simultaneously the operation of artificial assembling in field and maintenance widely, fitting operation is simpler, save the set-up time more than 10 times, because the aging-resistant time of hard PVC pipe in soil is longer, so the longer service life that new improved point oozes pipe.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

See Fig. 1, concrete structure is as follows: with the diameter 20mm that provides on the market, wall thickness 1mm, the PVC stereoplasm tube of length 5m oozes body 2 as point, according to the actual conditions of solanaceous vegetables cultivation, offer the micropore of diameter 1.0mm upwards above it every the 260mm segmentation, have the infiltration joint 3 long 50mm of micropore, 4 of micropore quantity, micropore spacing (hole centre-to-centre spacing) 20mm.Between the infiltration joint 3 is water delivery section 1.Point oozes an end 5 sealings of body 2, and the other end is cast with unidirectional dop 4 and is connected with the water delivery main line.This infiltrating irrigation pipe is embedded in the underground dark 30cm of crop row (ridge) place, and water irrigating hole upwards when burying underground; Therefore, two tube pitch equate with the crop row distance, promptly determine according to the raise crop needs.PVC hard point oozes the aperture and the quantity of managing micropore to be decided according to the water delivery speed of the vegetative stage of solanaceous vegetables water requirement maximum.

Claims

1, a kind of point oozes pipe, it is made with the hard PVC pipe, comprises body, it is characterized in that: the body that adopts hard PVC material to make is connected and composed by water delivery section and infiltration joint integral body, the length of water delivery section equals the spacing in the rows of solanaceous vegetables, has the one group of micropore that is directed upwardly on the infiltration joint.
