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

Abstract

The invention belongs to the technical field of agricultural water-saving irrigation and particularly relates to an economical anti-blocking gravity type underground drip irrigation system. The economical anti-blocking gravity type underground drip irrigation system comprises direct-current micro pump water lifting, water transportation and distribution, interval water supply and a pressure control irrigation device. The interval water supply device starts the pressure control irrigation device to conduct irrigation in cycles, and in each round of an irrigation process, mechanical dredging is conducted on a water outlet of the pressure control irrigation device, and therefore blocking of the water outlet of the irrigation device is effectively prevented. By means of the economical anti-blocking gravity type underground drip irrigation system, water feeding can use small water flow, an economical scheme for achieving anti-blocking gravity type drip irrigation for peasants poor in economic condition and small in operation scale in scattered non-electricity small-scale greenhouses, and water lifting and irrigation cost is low.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural water-saving irrigation, in particular to an economical 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 ...
