Anti-clogging drip irrigation emitter

Abstract

The invention belongs to the technical field of field irrigation, and particularly relates to an anti-blockage drip irrigation douche. The drip irrigation douche comprises a top cover, a dripper and a flow stabilizing valve, wherein an inner cavity of the dripper is divided into two parts, namely a water inlet cavity and a buffer cavity, by the flow stabilizing valve which is embedded into the inner cavity of the dripper and is a hollow conical body provided with a downward opening and of which the tip is provided with a crossed star-like cut; on the lower part of the buffer cavity, the hollow conical tip of the dripper is provided with a crossed cut; and the dripper is connected with a capillary pipe through the top cover. The drip irrigation douche has a pressure compensation function, can also guarantee the uniformity of irrigation under the condition of long capillary pipes or complex terrain, has self-flushing and automatic pressure boosting unblocking self-repair functions, can be used for resisting physical blockage and biological blockage, has superior anti-blockage performance and is particularly suitable for underground irrigation and under-film irrigation in which the drip irrigation douche is difficult to replace. The drip irrigation douche has a simple structure and high durability and is convenient to process, produce and use and low in investment.

Description

Technical field: [0001] The invention belongs to the technical field of farmland irrigation, in particular to an anti-clogging drip irrigation dispenser. 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 tasks, and is composed of water pumps or high-level pools, filters, fertilizer tanks, pressure gauges, flow meters and other components; ②The main pipe plays the role of water delivery; According to the size of the area and the water demand of the crop, the irrigation water is distributed to the irrigation area; ④The capillary pipe is connected with the branch pipe, and the water is sent to the root of the crop; ⑤Irrigators, including: drippers, water outlets, etc. To evenly moisten the soil at the root of the crop. Arranging drip irrigation capillari...

Problems solved by technology

Physical anti-clogging is a commonly used method. Professional researchers or folks have made unremitting efforts to improve the performance of physical anti-clogging methods. Related inventions and utility model patents continue to appear. The disadvantages of this method are still not well overcome. The reason is that the existing anti-clogging physical methods are not effective in removing the viscous blockage produced by biological bacteria, or even helpless, or the structure is too complicated, the investment is large, and production and construction are difficult. difficult to be widely used
