Abstract

The utility model relates to a drop irrigation belt in the form of variable pitch. A headpiece provided with an emitter is arranged on a hollow billet. A magnetic shim is positioned in the headpiece which is connected with the emitter by a screw thread or a neck, the drip irrigation point and the irrigation volume can be controlled effectively so as to reach the even drop irrigation of a drop irrigation system and adapt to the changes of crop spacing, varieties and farming seasons. The anticlogging performance is improved and the service life of the drop irrigation is prolonged because the headpiece has self-sealing function and the emitter can be replaced momentarily.

Description

The variable spacing irrigate band

One, technical field

The utility model belongs to the agricultural water-saving irrigation field, particularly a kind of variable spacing irrigate band.

Two, background technology

The international status of development of irrigating shows, drip irrigation system be save do not irrigate in the most effective New Water-saving Irrigation.It adapts to various landform, but Jiang Shui, fertile needs by crop are transported to crop root, make crop obtain its necessary moisture, thereby save the irrigation water total amount in a large number, can make the approximate stable humidity of soil conservation of crop root, create better growing conditions for crop, make crop yield more than 30%.The specific energy water-saving and electricity-saving is about 70% mutually to adopt drip irrigation and flood irrigation, saves fertilizer 20%, and the labour is more than 50% in saving.The main deficiency of present drip irrigation system is: for the internally-inlaid irrigate band, the spacing in its hole is fixed, thereby the spacing in the rows of crop is had strict requirement, and is simultaneously, relatively poor to the applicability of crop varieties; Need artificial punching for pipe following formula irrigate band, mounting pipe following formula water dropper again, inlet pressure skewness on whole irrigate band of the bothersome and water dropper of complex procedures.

Three, summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of and used flexibly, good reliability, installation easy to operate, easy, can be according to the different distance variable spacing of crop, the variable spacing irrigate band that head piece has self-enclosed function.

For achieving the above object, the technical solution adopted in the utility model is: hollow billet is provided with head piece, and head piece is provided with water dropper, is characterized in, is provided with the magnetic pad in the head piece, is connected by screw thread or draw-in groove between head piece and the water dropper.

Another characteristics of the present utility model are: the spacing of head piece is 0.08～0.1m.

Adopt the utility model can effectively control drip irrigation point and irrigation quantity, reach the even drip irrigation of drip irrigation system, can adapt to the variation of crop spacing in the rows, variety variations and variation in farming season, head piece has self-enclosed function, water dropper can be changed at any time, has improved anticlogging performance of drip irrigation system and service life.

Four, description of drawings

Fig. 1 is a structure principle chart of the present utility model;

Fig. 2 is the connection layout of the utility model head piece 2 and water dropper 3.

Five, embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.

Referring to Fig. 1,2, the utility model prefabricated spacing on hollow billet 1 is the head piece 2 of 0.08～0.1m, all crops of bases fit, be provided with magnetic pad 4 in the head piece 2, when in the hollow billet 1 during water flowing, head piece 2 is sealing automatically under the effect of hydraulic pressure and magnetic force, difference according to the Different Crop spacing in the rows, at the head piece 2 of correspondence by screw thread or the draw-in groove water dropper 3 that is connected, the water yield of the depth-adjustment restriction 2 that water dropper 3 inserts, when being used as the article kind and changing or change farming season, can adjust the position that water dropper 3 inserts at any time, to guarantee the water requirement of various crops in Various Seasonal.And its head piece 2 can seal automatically by magnetic pad 4 when taking off water dropper 3, can take off flushing or replacing when water dropper 3 stops up or damages at any time, can improve anticlogging performance of drip irrigation system and service life like this, tentatively realizes the irrigate band standardization.The unit are input of drip irrigation system is reduced, at common rural area use flexibly, good reliability, arrangement easy to operate, easy, good management, enlarge applying and applicable surface of drip irrigation system.
