Drip irrigation is the local irrigation of crops by delivering water through plastic pipes to the roots of crops through orifices or drippers on capillaries with the diameter of about 10 mm. It is the most effective water-saving irrigation mode in arid water-deficient areas at present, and the water utilization rate can reach 95%. Compared with spray irrigation, the drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to improve the fertilizer efficiency by more than one time. The irrigation system is suitable for irrigation of fruit trees, vegetables, economic crops and greenhouses, and can also be used for irrigation of field crops in arid places with water shortage.
The drip irrigation is a water irrigation method for uniformly and slowly dripping water and nutrients required by crops into soil in a crop root zone one drop by one drop through a pipeline system and an irrigation device arranged on a capillary according to the water requirement of the crops. The drip irrigation does not damage the soil structure, the water, fertilizer, gas and heat in the soil are always kept in good condition suitable for the growth of crops, the evaporation loss is small, no ground runoff is generated, and deep seepage is hardly caused, so that the drip irrigation is a water-saving irrigation mode.
However, drip irrigation has a significant disadvantage: clogging of emitters is the most important problem in current drip irrigation applications, and in severe cases, the whole system cannot work normally or even is scrapped. The blockage can be caused by physical factors, biological factors or chemical factors, such as silt, organic matters or microorganisms in water, chemical sediments and the like, which easily cause the blockage problem at the dripper.

8. The anti-blocking agricultural drip irrigation device with the self-cleaning dripper according to any one of claims 1 to 7, wherein: the using method comprises the following steps:
s1, installing the drip irrigation pipeline (1) at a farmland to be irrigated, connecting the water inlet end of the drip irrigation pipeline (1) with a water delivery device, and gradually dripping water along a water dropper (2) when the water delivery device delivers water into the drip irrigation pipeline (1);
s2, dripping water drops in the dripper (2) on the air bag (6), wherein one part of water flows downwards along the surface of the air bag (6) and drips on soil, and the other part of water flows into the water storage tank (601) along the surface of the air bag (6) and is stored;
S3, when water gradually gathers in the water storage tank (601), the weight of the air bag (6) is gradually increased, the gravity center of the air bag (6) is gradually inclined, the air bag (6) is gradually inclined while moving downwards, the first elastic rope (4), the second elastic rope (5), the third elastic rope (8) and the fourth elastic rope (10) are gradually extended, the position control plate (9) gradually moves downwards to extrude the stop block (12) and the compression spring (13);
s4, when the water in the water storage tank (601) is accumulated to a certain content, the stop block (12) is completely extruded into the inner tank (201) by the control plate (9), and the air bag (6) rapidly descends and topples over;
s5, after most of water in the water storage tank (601) is poured out, the gravity of the air bag (6) is quickly reduced, the air bag rebounds upwards and is gradually leveled, and under the action of elasticity, the air bag (6) continuously makes up-and-down elastic motion for a period of time, so that the second elastic rope (5) drives the dredger (7) to move up and down to dredge the interior of the dropper (2);
and S6, spontaneously repeating the processes from S2 to S5, and realizing the self-cleaning process of the dripper (2).
