Problems solved by technology

However, the biggest problem with drip irrigation used in real life is that the drip holes are easily blocked. Due to the small pores of the drip holes, the accumulation and precipitation of impurities and minerals in the irrigation water can easily lead to blockage of the drip holes, which in turn affects the irrigation of the entire drip irrigation system. Uniformity
The cost of the drip irrigation system is high, and drip irrigation has high requirements on the water quality of the water source, so the water source should be strictly filtered, which will undoubtedly greatly increase the cost of drip irrigation
At the same time, due to the water pressure problem, the drip hole closer to the water inlet will have a faster drip speed, and the drip hole farther from the water inlet will have a slower drip speed or even no drip, resulting in uneven drip irrigation and affecting production; Moreover, the existing drip irrigation device can only irrigate within a fixed range, and cannot realize flexible changes in the irrigation area and fixed-point water delivery irrigation, resulting in waste of water resources

Embodiment 1

[0033] see Figure 1-Figure 3 , an anti-clogging drip irrigation device, comprising a main pipeline 1 for delivering irrigation water and a water delivery rope 2 for delivering irrigation water, one end of the water delivery rope 2 extends into the main pipeline 1, and the other end extends to the soil The water delivery rope 2 has a capillary structure, and the irrigation water is transported into the soil by the main pipeline 1 under the drive of capillary force.

[0034] see Figure 4 , the water delivery rope 2 also includes a trunk 2-1 and a plurality of sub-trunks 2-2, and one end of the plurality of sub-trunks 2-2 is respectively connected to the trunk 2 along the extending direction of the trunk 2-1. -1, the other end is connected to the soil. In the prior art, not only the irrigation area of ​​a single dripper remains unchanged, but also the irrigation area is usually fixed, resulting in the inability to accurately irrigate the entire range and the flexibility of irr...

Embodiment 2

[0047] see Figure 5 , different from Embodiment 1, the water delivery rope 2 also includes a trunk 2-1 and a plurality of sub-trunks 2-2, one end of the plurality of sub-trunks 2-2 and the middle of the trunk 2-1 They are connected at the same point, and the other ends extend in different directions to connect with the soil. Irrigation can be flexibly implemented through different connection methods.

Embodiment 3

[0049] see Figure 1-Figure 3 , in this embodiment, different from Embodiments 1 and 2, the branch pipe 3 is connected to the branch hole 1-1 through a threaded connection; wherein, one end of the branch pipe 3 is provided with an internal thread, and the The distribution hole 1 - 1 is provided with an external thread that cooperates with the internal thread of the branch pipe 3 . The threaded connection design can better connect the sub-pipe 3 with the main pipe 1, and it is easy to disassemble and assemble, and has a good sealing effect.

[0050] see Figure 1-Figure 3 , the end of the branch pipe 3 away from the branch hole 1-1 is provided with an external thread, and the external thread can cooperate with the internal thread at one end of the branch pipe 3. Its function is that when the length of the branch pipe 3 is not enough , several sub-pipes 3 can be spliced ​​through screw connections, and the flexibility of irrigation is improved in terms of installation.

Abstract

The invention discloses an anti-blocking drip irrigation device which comprises a main pipeline for conveying irrigation water and a water conveying rope for conveying irrigation water. One end of thewater conveying rope extends into the main pipeline, and the other end of the water conveying rope extends into soil and makes contact with the soil; the water conveying rope has a capillary structure, and the irrigation water is conveyed from the main pipeline into the soil under the driving of capillary action force. The drip irrigation device has high anti-blocking performance and can realizesynchronous irrigation and fertilization, flexible change of irrigation areas and fixed-point irrigation; in addition, the drip irrigation device does not need large water pressure, so that the irrigation cost is saved; moreover, the drip irrigation device achieves a uniform drip irrigation effect, so that the water utilization rate is greatly increased.

Description

technical field [0001] The invention relates to the technical field of irrigation pipes, in particular to an anti-clogging drip irrigation device. Background technique [0002] Drip irrigation is currently a more advanced water-saving irrigation method in farmland irrigation, which can effectively improve the utilization rate of water resources. Under drip irrigation, because the irrigation water does not move in the air, it only wets part of the soil surface, which can effectively reduce the ineffective evaporation of soil moisture. . At the same time, the soil moisture content in other areas is low, thus, preventing the growth of weeds. The drip irrigation system does not produce surface runoff, and it is easy to grasp the precise depth of water application, which is very water-saving. Because drip irrigation can supply water and fertilizer in a timely and appropriate amount, it can improve the quality of agricultural products while increasing the yield of crops, so that...
