Flat irrigation water dropper with novel side water inlet structure and using method of flat irrigation water dropper

Abstract

The invention relates to a flat irrigation water dropper with a novel side water inlet structure and a using method of the flat irrigation water dropper. A plurality of flat irrigation water droppersare pressed on a capillary tube at intervals along the inner surface of the length direction of the capillary tube, and water outlet buffer grooves of the flat irrigation water droppers correspond towater outlet holes of the capillary tube; in operation, due to the action of water pressure, water in the capillary tube can enter water inlet buffer grooves through a plurality of water inlets from sunken surface water inlet surfaces of the bottom surfaces of the flat irrigation water droppers at the same time, and enter the water inlet buffer grooves through a plurality of water inlets in the side surfaces, and the water entering the water inlet buffer grooves enters the water outlet buffer grooves through a U-shaped runner groove for buffering and fully dissipating energy, finally flows outof the water outlet holes of the capillary tube, and is dropwise added into soil to be irrigated. According to the invention, a mode of feeding water from the side surfaces and the bottom surface simultaneously in different directions is adopted, thus, a function of oppositely flushing water flow can be fulfilled, impurities such as fine sand in the water can be flushed away, the problem of easiness in blockage of a flat water dropper troubling drip irrigation manufacturers for many years is thoroughly solved, and reliable guarantee is provided for large-area irrigation of a farmland.

Description

technical field [0001] The invention belongs to the technical field of water-saving irrigation in agricultural production, and in particular relates to a novel flat irrigation dripper with a side water inlet structure and a use method thereof. Background technique [0002] my country is one of the countries with poor water resources in the world, especially in the northern region, where the arable land accounts for 45% of the country's total, but water resources only account for 9.7% of the country's total. Drip irrigation is one of the most water-saving irrigation technologies for farmland irrigation so far. According to the water requirements of crops, drip irrigation uses low-pressure piping systems and irrigators installed on capillary tubes to drip water and nutrients needed by crops evenly and slowly. The irrigation method in the soil of crop root zone is a scientific and efficient irrigation method. As a manufacturer of drip irrigation products, due to the structural...

Problems solved by technology

As a manufacturer of drip irrigation products, due to the structural constraints of traditional dripper products, such as Figure 5 and Image 6 As shown, the water inlet is set at the bottom of the dripper, and the water enters the upper part of the dripper from the water inlet at the bottom of the dripper, and drip irrigation is realized through the flow channel and the water outlet buffer tank. Due to the limitation of the product structure, the shortcoming is the flow area of ​​the bottom water inlet Smaller, when the drip irrigation belt is not in use, the drip irrigation belt will shrink due to no water pressure, and impurities in the water such as fine sand will slowly deposit at the water inlet at the bottom of the dripper, forming a coupling deposit layer to block the water inlet of the dripper , resulting in product clogging and poor clogging resistance. During the use of farmers, the dripper on the capillary is clogged and no water is produced, resulting in frequent droughts and reduced production of crops, resulting in irreparable economic losses.
