Description
Technical Field
The application relates to the technical field of agricultural irrigation, in particular to an anti-blocking underground drip irrigation emitter.
Background
The underground drip irrigation is an efficient water-saving irrigation technology, the underground drip irrigation emitter is buried underground, irrigation water and fertilizer can be directly delivered to a crop root area, surface evaporation and deep leakage are effectively reduced, and the utilization rate of water is improved. However, as the capillary or the dripper is directly buried in the soil, the water outlet is easy to be blocked, so that the popularization and the application of the capillary or the dripper are limited to a certain extent. Causes of subsurface drip irrigation clogging can be classified into soil particle clogging and crop root clogging. The main reason for soil particle blockage is that the inner wall of the dripper flow channel is not smooth enough, fine particles entering the flow channel are easy to attach to the flow channel wall to form a plug core, and the plug core is combined with other tiny particles to form a plug-shaped mud mass. The blockage of the crop root system is mainly caused by the fact that the plant root system grows towards the water, so that the root system invades into a water outlet of a capillary to cause blockage.
At present, a solution to soil particle blockage is mainly started from water quality, water entering a drip irrigation system does primary physical sedimentation on irrigation water in a water source area, and filters need to be installed in each stage of pipe network of the drip irrigation system, so that the construction and management cost of the system is undoubtedly increased.
At present, the method for solving the root system blockage of the crops mainly starts from two aspects of production special equipment and chemical substance injection into a system. Firstly, the anti-clogging of chemistry protectiveness water dropper, the main process is during the plastics polymer of mixing the water dropper with weedicide trifluralin, and trifluralin releases with the steam form according to certain speed, mixes with soil around the water dropper, can restrain the root system to near the growth of water dropper. Trifluralin can kill root systems around drip irrigation and cause damage to the growth of normal crop root systems, so that crop yield is reduced. In addition, the production process of such products is very complex. The chemical protective filter is anti-clogging, and the principle is that a replaceable medicine barrel is arranged in the laminated filter, trifluralin is arranged in the replaceable medicine barrel, a device for preventing medicine from flowing reversely or leaking is further arranged, and the medicine is carried to soil around a dripper by water during system irrigation to prevent root systems from invading the dripper. However, at the end of the filter life, the drug barrel needs to be replaced again, and the drug adding in the filter is more susceptible to the temperature than the drug adding in the dropper, so that the stability of the release rate is also poorer than that of the dropper. And long-term use can not only damage crops, but also have negative effects on soil.

Assume that the height of each layer of the flow-path structure 11 of the emitter is h. Assuming that irrigation water passes between adjacent concentric rings, the total length L of the 3-layer flow channels is as follows:
regardless of the thickness of the third layer of emitter, the total length of the central path of water from the LCR3401 water chamber into the first connecting tube segment 21 is:
irrigation emitter of the same size circumference, ifSingle ring, the shortest distance of root system entering the center of the first section of connecting pipe 21 is R4The emitter flow path length described herein is [6 x π (R) for a single ring emitter1+R2+R3+(R0+R4)/2)+2h]/R4And (4) doubling. If the number of the rings is more, the length of the flow passage is multiplied, and the anti-blocking effect is better.
Moreover, the proper size of the flow channel can be selected according to the actual size of the crops, so that when the root systems of the crops enter the inside of the irrigator through the water permeable holes on the side wall of the irrigator body, the design method can further reduce the risk of root system blockage due to the fact that the cavities of the independent water chambers are larger than the diameter of the root systems of the crops.

Irrigation water enters the first flow channel structure from the bottom of the connecting pipe from top to bottom through the connecting pipe, and then enters soil from bottom to top according to the first flow channel structure, the second flow channel structure and the third flow channel structure.
