Pipe blockage will then affect the drip irrigation operation and the growth of blueberries. Therefore, how to prevent the drip irrigation device from being blocked and how to clear it in time after blockage is a problem that needs to be solved. Utility Model Content

[0004] In order to solve the technical problem of pipeline blockage during drip irrigation, the utility model provides a drip irrigation system for blueberry planting.

[0005] The utility model adopts the following technical scheme to achieve: a drip irrigation system for blueberry planting, comprising:

[0006] A water storage tank; the water storage tank is used to temporarily store water for drip irrigation, and a primary filter layer is provided in the water storage tank;

[0009] Flushing pipe; one end of the flushing pipe is connected to the side of the water distribution pipe close to the secondary filter box.

[0010] Through the above technical solution, the primary filter layer and the secondary filter box can filter the irrigation water, remove large particles of impurities, and prevent impurities from accumulating in thinner pipes, blocking the annular drip emitter and affecting the drip irrigation operation. At the same time, by passing pressurized water into the flushing pipe, it can help flush the water distribution pipe and prevent impurities from accumulating in the water distribution pipe and affecting subsequent drip irrigation operations.

[0011] As a further improvement of the above solution, a rib is provided on the inner wall of the water storage tank, a mounting net is provided on the rib, and the primary filter layer is provided in the mounting net.

[0012] Through the above technical solution, the installation net is directly placed on the retaining edge, that is, when the primary filter layer needs to be replaced later, the installation net can be directly taken out. The primary filter layer can use quartz sand as the medium.

[0013] As a further improvement of the above scheme, the secondary filter box and the water storage tank are connected via a water inlet pipe, a No. 1 control valve is installed on the water inlet pipe, and a No. 2 control valve is provided between the secondary filter box and the water distribution pipe.

At this time, the drain wire plug is opened, and the water after flushing is discharged from one end of the water distribution pipe where the drain wire plug is installed.

[0019] As a further improvement of the above solution, a filter screen is installed in the secondary filter box.

[0020] Through the above technical solution, the pull-out filter screen in the secondary filter box not only plays the role of secondary filtration, but also makes it convenient to open the secondary filter box and directly put the medicine to be watered into the secondary filter box.

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0029] Please combine Figure 1 - Figure 4 A drip irrigation system for blueberry planting in this embodiment includes a water tank 1, which is used to temporarily store water for irrigation. A primary filter layer 4 is arranged in the water tank 1. The primary filter layer 4 can use quartz sand as a medium to filter the irrigation water through the quartz sand. In order to facilitate the cleaning of the inside of the water tank 1 and the replacement of the primary filter layer 4, a rib 2 and an installation net 3 are also arranged inside the water tank 1, wherein the rib 2 is welded and fixed on the inner wall of the water tank 1, and the primary filter layer 4 with quartz sand as a medium is placed in the installation net 3, and the installation net 3 is integrally overlapped on the rib 2. The primary filter layer 4 can filter impurities in the water. In addition, when it needs to be replaced, the water tank 1 can be directly opened and the installation net 3 can be taken out.

[0030] A secondary filter box 6 is also provided on one side of the water storage tank 1. The secondary filter box 6 is connected to the water storage tank 1 through a water inlet pipe 5. A first control valve 8 is installed on the water inlet pipe 5. A card slot is provided on the inner wall of the secondary filter box 6, and a filter screen plate 7 is connected in the card slot. The filter screen plate 7 can perform secondary filtering on water.

[0031] The other side of the secondary filter box 6 is also connected to a water distribution pipe 10. In this embodiment, four water distribution pipes 10 are provided. A second control valve 9 is installed at the connection between the water distribution pipe 10 and the secondary filter box 6.

[0032] In addition, a plurality of annular drippers 12 are connected to the water distribution pipe 10. The top of the annular drippers 12 and the water distribution pipe 10 are connected through a connecting capillary 11. Capillary water pipes distributed in an annular pattern are arranged inside the annular drippers 12, and water outlets are distributed in a circular pattern at the bottom. That is, the water in the water distribution pipe 10 flows into the annular drippers 12 after passing through the connecting capillary 11. The annular drippers 12 are circular and evenly irrigate the water around the root system of the blueberry plant. This facilitates the soil to absorb water better, and avoids the water flow being concentrated in one place, causing water accumulation, or even soaking the blueberry root system, causing root rot.

[0033] In addition, in order to prevent the annular dripper 12 from directly contacting the soil and preventing sand particles from clogging the annular dripper 12, a fixing block 13 is fixedly connected to one side of the annular dripper 12, wherein the fixing block 13 is provided with a threaded hole and connected to a fixing rod 14, and the lower end of the fixing rod 14 is tapered, which is convenient for direct insertion into the soil. The fixing rod 14 is rotated to control the depth of the fixing rod 14 inserted into the soil, thereby facilitating the adjustment of the height of the annular dripper 12 so that it is located above the soil layer, thereby preventing soil particles from clogging the annular dripper 12.

[0034] Although the primary filter layer 4 and the secondary filter box 6 can filter the water flow and remove the suspended matter, organic matter and algae in the water may still grow in the water distribution pipe 10, gradually forming dirt and clogging, and even calcium, magnesium and other substances dissolved in the water may precipitate when encountering oxygen or other chemical substances, forming scale.

[0035] In order to facilitate cleaning of the water distribution pipe 10, a flushing pipe 16 is connected to the side of the water distribution pipe 10 close to the secondary filter box 6, and a No. 3 control valve 17 is installed on the flushing pipe 16. In addition, a drainage wire plug 15 is connected to the end of the water distribution pipe 10 away from the secondary filter box 6.

[0036] During normal use, the drain plug 15 is closed, blocking the water distribution pipe 10. When the water distribution pipe 10 needs to be flushed, the No. 1 control valve 8 and the No. 2 control valve 9 are closed, and the No. 3 control valve 17 and the drain plug 15 are opened. At this time, high-pressure water flow is introduced into the flushing pipe 16, and the water flow passes through the flushing pipe 16 and the water distribution pipe 10, rushes out from the other end of the water distribution pipe 10, and flushes the inside of the water distribution pipe 10. This prevents the inner wall of the water distribution pipe 10 from being blocked by sedimentation, which affects the subsequent drip irrigation operation.

[0037] The implementation process and principle of a drip irrigation system for blueberry planting in the embodiment of the present application are as follows:

[0038] (i) When in use, water flows from the water storage tank 1 through the primary filter layer 4 with quartz sand as the medium and the filter screen 7 in the secondary filter box 6, which can remove most of the suspended matter and impurities in the water, reduce the risk of precipitation and siltation in the water distribution pipe 10, and ensure that the drip irrigation operation can proceed normally.

[0039] (ii) Water flows from the water storage tank 1 through the water inlet pipe 5, the water distribution pipe 10, the connecting capillary 11, and finally flows out from the lower water outlet of the annular drip irrigator 12 to drip irrigate the blueberry plants. During this process, the fixing rod 14 can control the height of the annular drip irrigator 12 to avoid direct contact between the annular drip irrigator 12 and the soil, thereby reducing the risk of soil adhesion or even entering the water outlet of the drip irrigator and reducing the risk of failure of the annular drip irrigator 12. In addition, the water flowing out of the annular drip irrigator 12 is evenly irrigated around the root system of the blueberry plant. This can prevent the water flow from being concentrated in one place, causing water accumulation or even soaking the blueberry roots, causing root rot.

[0040] (III): When it is necessary to flush the water distribution pipe 10, close the No. 1 control valve 8 and the No. 2 control valve 9, open the No. 3 control valve 17 and the drain plug 15, and then introduce high-pressure water into the flushing pipe 16. The water flows through the flushing pipe 16 and the water distribution pipe 10, and rushes out from the other end of the water distribution pipe 10 to flush the water distribution pipe 10. This prevents the inner wall from being blocked by sedimentation and affecting the drip irrigation operation.

[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
