Anti-clogging drop irrigation device

Abstract

The invention discloses an anti-clogging drop irrigation device. The anti-clogging drop irrigation device comprises a dropper and a centrifugal filter, the left side face and the right side face of the inner wall of the dropper are fixedly connected with the left side face and the right side face of a filter plate, a sliding sleeve is in clamping connection with the upper surface of the filter plate, a slide rod is slidably connected with the interior of the sliding sleeve, and the bottom end of the slide rod extends to the outer part of the dropper and is fixedly connected with the upper surface of a jacking head. The anti-clogging drop irrigation device is characterized in that, through mutual cooperation of a sealing block, a water leaking hole, the filter plate, a spring, the slide rod, the sliding sleeve, the jacking head, an extrusion device and the sealing block, when the dropper is inserted into the position of the soil where the plant root is located, the sealing block moves downwards to push the slide rod to slide downwards and extrude the spring to shrink, the jacking head moves downwards under driving of the slide rod to extrude the soil entering the dropper out, the filter plate can stop the soil from entering and clogging the water leaking hole, the mud on the filter plate is washed through the water flow, and thus the dropper is ensured to be always clear in theusing process.

Description

technical field [0001] The invention relates to the technical field of drip irrigation devices, in particular to an anti-clogging drip irrigation device. Background technique [0002] Drip irrigation uses plastic pipes to send water to the roots of crops through holes or drippers on capillaries with a diameter of about 10mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing production. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and can also be used for irrigation of field crops in places where there is drought and water shortage. Its disadvantage is that the dripper is easy to scale and block, so the water sourc...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-clogging drip irrigation device, which solves the problem that during the drip irrigation process, the nozzle is often inserted directly into the soil at the root of the plant, and the soil enters the dropper, which easily causes the blockage of the dripper. The content of solid impurities in the water is high, and solid particles are easy to enter the drip irrigation system, which will block the emitters such as drippers, thereby paralyzing the entire micro-irrigation system.
