Example Embodiment

[0030] The present invention will be further described in conjunction with the accompanying drawings and specific examples.

[0031] like Figure 1 to 7 As shown, an external patch-type variable flow anti-blocking belt includes a drip irrigation housing 2 mounted on the surface of the drip irrigation pipe 1, the drip tube 1 surface is opened with a water hole 3, the droplet body The 2 inlet end is in communication with the outlet hole 3, and the dripper body 2 is provided with a fixed rack 4 and a moving rack 5, and the fixed rack 4 and the moving rack 5 form a labyrinth channel 6 The labyrinate flow path 6 inlet end is in-water end and the drip irrigation housing 2, and the water end is in communication with the drop irrigation hole 7.

[0032] Preferably, the fixed rack 4 is fixed to the inside of the dripper body 2, the spacing between the moving racks 5 and the fixed rack 4, which further adjusts the laze channel 6 cavity to the surface size. In the present embodiment, when the...

Abstract

The invention discloses an external patch type variable flow channel anti-blocking drip irrigation tape and an anti-blocking drip irrigation method. The anti-blocking drip irrigation tape comprises a drip irrigation shell installed on the surface of a drip irrigation tape pipeline, water outlet holes are formed in the surface of the drip irrigation tape pipeline, the water inlet end of the drip irrigation shell communicates with the water outlet holes, a fixed rack and a movable rack are arranged in the drip irrigation shell, a labyrinth flow channel is formed between opposite teeth of the fixed rack and the movable rack, the water inlet end of the labyrinth flow channel communicates with the water inlet end of the drip irrigation shell, and the water outlet end of the labyrinth flow channel communicates with the drip irrigation holes. Under the condition that the drip irrigation tape does not need to be replaced, normal water outlet of a blocked water dropper is recovered, so that the purposes of improving the irrigation uniformity and prolonging the service life of the drip irrigation tape are achieved.

Description

technical field [0001] The invention relates to the field of agricultural water-saving irrigation design, in particular to an external patch type variable channel anti-clogging drip irrigation belt and an anti-clogging drip irrigation method. Background technique [0002] Drip irrigation is widely used as an efficient water-saving irrigation technology, and the patch drip irrigation belt is widely used because of its simple installation and low cost. When the water quality is poor or the filter is not used properly, the dripper of the drip irrigation belt is often blocked, which seriously affects the service life and irrigation efficiency of the drip irrigation belt. How to restore the blocked dripper to normal water outlet without replacing the drip irrigation belt, so as to improve the uniformity of irrigation and prolong the service life of the drip irrigation belt has become the key to the development of drip irrigation belt technology. Contents of the invention [00...
