Problems solved by technology

[0003] However, after 2 years of operation of the gravity drip irrigation system of the prior art, the clogging of the emitter generally exceeds 10%, which is much larger than that of the conventional drip irrigation system
The gravity drip irrigation system lacks the most critical anti-clogging proprietary technology, which is the main problem and bottleneck faced by the large-scale application of the gravity drip irrigation system

Embodiment Construction

[0016] An anti-clogging gravity type underground drip irrigation system, as attached figure 1 , 2, 3 and 4, including four parts: water storage, water distribution, intermittent water supply and pressure control irrigation device, the water storage part consists of a water storage tank, a water injection port on the upper part of the water storage tank, and a water outlet on the lower part of the water storage tank It is composed of a water outlet valve connected to the water outlet at the lower part of the water storage tank. The water storage tank is placed on an elevated position. The height of the water outlet at the lower part of the water storage tank is greater than the height of the upper water pipe 21-1 of the water storage container. Composed of main water pipe, filter, main sewer pipe, branch pipe and capillary pipe, the upper water pipe 21-1 of the water storage container is connected to the other end of the water outlet valve connected to the water outlet at the l...

Abstract

The invention belongs to the technical field of agricultural water-saving irrigation and particularly relates to an anti-clogging gravity type underground drip irrigation system. The anti-clogging gravity type underground drip irrigation system comprises a water storage device, a water delivery and distribution device, an intermittent water supply device and a pressure control irrigation emitter, wherein the intermittent water supply device recurrently starts the pressure control irrigation emitter to perform irrigation; and during each round of irrigation process, an irrigation emitter water outlet of the pressure control irrigation emitter is mechanically dredged, thus effectively preventing the clogging of the irrigation emitter water outlet. The most common gravity type drip irrigation system provided by the invention adopts a special anti-clogging technical method for the gravity type drip irrigation system, and effectively solves the problem that the irrigation emitter of the most common gravity type drip irrigation system is easy to clog.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural water-saving irrigation, in particular to an anti-clogging gravity underground drip irrigation system. Background technique: [0002] Drip irrigation is a kind of local irrigation, which consists of five parts: the first hub, the main pipe, the branch pipe, the capillary pipe, and the sprinkler. ①The head hub is responsible for water intake, pressurization and water treatment, and is composed of water pumps, fertilizer tanks, filters, pressure gauges, flow meters and other components; ②The main pipe plays the role of water delivery; Crop water demand, distribute irrigation water to the irrigation area; ④ Capillary pipes are connected with branch pipes to send water to the roots of crops; ⑤ Irrigators, including: drippers, water outlets, etc., have different types and shapes to Moisten the soil at the root of the crop. Arranging drip irrigation capillaries and emitters under the surface is ...
