Drip irrigation micro sprinkler for irrigating fertilizing and applying pesticide

Abstract

The invention discloses a drip irrigation micro sprinkler for irrigating fertilizing and applying pesticide. The drip irrigation micro sprinkler comprises a water storing drum body and a drip irrigation pipeline, wherein the upper end of the water storing drum body is connected with a water source through a water suction pump and a pipeline; a centrifugal filter is arranged on the pipeline between the water suction pump and the water storing drum body; a stirring device is arranged inside the water storing drum body; a pesticide adding inlet is formed in the side part of the top end of the water storing drum body; the lower end of the water storing drum body communicates with the drip irrigation pipeline through a first water supplying pump and a pipeline; a screen filter and a laminated filter are sequentially arranged on the pipeline between the first water supplying pump and the drip irrigation pipeline; the drip irrigation pipeline comprises a drip irrigation main pipe which is correspondingly connected with a water outlet of the first water supplying pump and a plurality of drip irrigation branched pipes connected onto the drip irrigation main pipe. The drip irrigation micro sprinkler disclosed by the invention has the advantages that structural design is reasonable, and convenience in operation and use is realized; the functions of automatic uniform irrigation, and applying irrigation of pesticide and fertilizer can be realized, water in soil can be effectively increased, the humidity of air is favorably improved, and the effect of adjusting microclimate is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a drip irrigation micro-sprinkler for irrigation, fertilization and pesticide application. Background technique [0002] Drip irrigation is the use of 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, and the water utilization rate can reach 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. During use, a small am...

Problems solved by technology

During use, a small amount of soil, sand, crop roots and other impurities enter the drip irrigation pores from the outside, which will block the drip irrigation holes, resulting in unsmooth water outlet and even making it difficult for the water to penetrate out, affecting the use effect and life; when the water source contains impurities More often, the drip irrigation pipeline will be blocked from the inside, affecting the drip irrigation effect; in addition, the existing drip irrigation equipment has a single function, and the pesticide spraying or fertilization of crops needs to be carried out separately, which requires additional labor costs and equipment. cost
