Detailed Implementation

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The potato-maize intercropping drip irrigation system of this invention includes a water pump 100, a filter unit 200, a water outlet pipe 300, and a cleaning assembly 500. The inlet of the water pump 100 is connected to a water source. The filter unit 200 includes a first filter 1 and a second filter 2. The inlet of the first filter 1 is connected to the outlet of the water pump 100, and the outlet of the first filter 1 is connected to the second filter 2. The inlet of the water outlet pipe 300 is connected to the second filter 2. The cleaning assembly 500 includes a support frame 10, a water inlet pipe 11, and a plurality of nozzles 12. The support frame 10 and the second filter 2 are arranged at intervals in the direction of liquid flow. The inlet of the water inlet pipe 11 is connected to the outlet of the first filter 1. The plurality of nozzles 12 are respectively connected to the water inlet pipe 11, and the plurality of nozzles 12 are arranged at intervals along the width direction of the second filter 2. The outlet of the nozzles 12 faces the second filter 2.

[0026] Specifically, such as Figure 1 As shown, the inlet of water pump 100 is connected to a water source via a pipe, which can be a well or a water storage tank. For example, the head of water pump 100 is 65.55m, and the total flow rate is 75.735m³ / h. 3 / h. A water pump 100 manufactured by Tianjin Aote Pump Industry, model 200QJ80-66 / 6, with an outlet diameter of 4", and a matching motor power of 22Kw can be selected.

[0027] For example, the first filter 1 is a water-sand separator, and the second filter 2 is a screen filter. The first filter 1 is located upstream of the second filter 2. In other words, the water discharged by the water pump 100 first passes through the first filter 1, then through the second filter 2, and finally is discharged through the outlet pipe 300.

[0028] Specifically, such as Figure 2As shown, the cleaning assembly 500 is connected to the second filter 2 through the housing 14. In other words, the cleaning assembly 500 is located downstream of the second filter 2. The support frame 10 extends in the vertical direction and is provided with a guide groove. The guide groove extends in the vertical direction, and the water inlet pipe 11 extends in the front-back direction. The front and rear ends of the water inlet pipe 11 are respectively locked in the guide groove.

[0029] Optionally, the nozzle 12 is movable in the height direction of the support frame 10. It should be noted that the water inlet pipe 11 is a PE pipe, and multiple nozzles 12 are respectively connected to the water inlet pipe 11, with the outlet of the nozzle 12 facing the second filter 2. A telescopic cylinder 16 is connected to the upper end of the water inlet pipe 11. The telescopic cylinder 16 is sealed to the external pipe of the cleaning assembly 500; in other words, the telescopic end of the telescopic cylinder 16 is sealed to the pipe, for example, through a sealing sleeve.

[0030] Optionally, a hatch (not shown) may be installed between the second filter 2 and the cleaning assembly 500. The hatch can be moved up and down by an electric push rod, a hydraulic rod or a cylinder to connect or disconnect the cleaning assembly 500 and the second filter 2.

[0031] When the second filter 2 needs to be cleaned, the hatch can be opened and the connection between the second filter 2 and the outlet pipe 300 can be disconnected, and the second filter 2 can be flushed. When the second filter 2 does not need to be cleaned, the hatch can be closed, and the water flows into the outlet pipe 300 after being filtered by the second filter 2.

[0032] Optionally, a sealing strip 15 is installed between the second filter 2 and the housing 14 of the cleaning assembly 500 to improve the sealing between the cleaning assembly 500 and the second filter 2.

[0033] The soybean-corn intercropping drip irrigation system of this utility model uses a first filter 1 to separate water and sand from the water source, preventing sand from clogging the emitters. A second filter 2 is used for further filtration, which further improves the purity of the water entering the drip irrigation unit 400 and reduces the risk of clogging. The cleaning component 500 can periodically clean the second filter 2 to ensure the flow of water and the filtration quality of the second filter 2, thereby reducing the risk of clogging.

[0034] This utility model of a potato-corn intercropping drip irrigation system can reduce the risk of clogging of the irrigation device.

[0035] In some embodiments, the burial depth of the outlet pipe 300 is A, and 0.7m≤A≤1.5m.

[0036] For example, the burial depth of the outlet pipe 300 can be 0.7m, 0.8m, 0.9m, 1m, 1.1m, or 1.2m. It should be noted that if the burial depth of the outlet pipe 300 is too shallow, not only will the water discharged from the drip irrigation tape evaporate more easily, but it will also make it difficult for the water to reach the crop roots, affecting the irrigation effect. Conversely, if the burial depth of the outlet pipe 300 is too deep, it will not only increase the cost of trench excavation but also lead to water loss.

[0037] In some embodiments, the potato-maize intercropping drip irrigation system further includes a drip irrigation unit 400, which includes multiple first drip irrigation pipes 5 and multiple second drip irrigation pipes 6. The multiple first drip irrigation pipes 5 are arranged at intervals of a first preset distance B, where 1.5m ≤ B ≤ 2.5m, and the multiple second drip irrigation pipes 6 are arranged at intervals of a second preset distance C, where 1.5m ≤ C ≤ 2.5m.

[0038] Specifically, such as Figure 3 As shown, the first preset distance between two adjacent first drip irrigation pipes 5 can be 1.5m, 1.6m, 1.7m, 1.8m, 1.9m, 2m, 2.1m, or 2.2m. The second preset distance between two adjacent second drip irrigation pipes 6 can be 1.5m, 1.6m, 1.7m, 1.8m, 1.9m, 2m, 2.1m, or 2.2m.

[0039] It should be noted that the first and second preset distances can be the same, for example, both can be 2m. When the first and second preset distances are too small, the irrigation areas between two adjacent drip irrigation pipes overlap, leading to a waste of water resources. Conversely, when the preset distances are too large, the interval between the irrigation areas of two adjacent drip irrigation pipes becomes too large, affecting the water absorption effect of the crop roots.

[0040] In some embodiments, the drip irrigation unit 400 further includes a plurality of drippers 7, which are respectively installed on the first drip irrigation pipe 5 and the second drip irrigation pipe 6, and the plurality of drippers 7 are arranged at intervals in the extension direction of the drip irrigation pipe, with the interval between two adjacent drippers 7 being D, and 0.2m≤D≤0.6m.

[0041] Specifically, such as Figure 2 As shown, the spacing between two adjacent drippers 7 on the first drip irrigation pipe 5 can be 0.2m, 0.3m, 0.4m, 0.5m, or 0.6m. It should be noted that if the spacing between two adjacent drippers 7 is too small, the irrigation areas of the two drippers 7 will overlap, leading to water waste. Conversely, if the spacing is too large, the irrigation areas of the two drippers 7 will be too far apart, affecting the water absorption effect of the crop roots.

[0042] In some embodiments, a support portion 8 is provided at the connection between the first drip irrigation pipe 5 and the outlet pipe 300 or at the bend of the first drip irrigation pipe 5. The drip irrigation pipe and the outlet pipe 300 pass through the support portion 8, and the distance between the outer surface of the first drip irrigation pipe 5 and the outlet pipe 300 and the outer surface of the support portion 8 is the same. A support portion 8 is provided at the connection between the second drip irrigation pipe 6 and the outlet pipe 300 or at the bend of the second drip irrigation pipe 6. The drip irrigation pipe and the outlet pipe 300 pass through the support portion 8, and the distance between the outer surface of the second drip irrigation pipe 6 and the outlet pipe 300 and the outer surface of the support portion 8 is the same.

[0043] It should be noted that, as Figure 5 As shown, when the diameters of the first drip irrigation pipe 5, the second drip irrigation pipe 6, and the outlet pipe 300 are greater than 50mm, support parts 8 are installed at the bends, diameter changes, and branching points of the pipes. The support parts 8 are closed structures, with the pipes passing through them. The distance between the first drip irrigation pipe 5 and the outer surface of the support part 8 is 20mm, and the distance between the second drip irrigation pipe 6 and the outer surface of the support part 8 is 20mm. Using the support parts 8 to support the pipes improves their stability.

[0044] In some embodiments, the potato-maize intercropping drip irrigation system further includes a switch valve 3, which is installed at the outlet of the drip irrigation pipe and placed inside a valve chamber 4, which is buried in the ground.

[0045] Specifically, such as Figure 4 As shown, valve chamber 4 is a drainage well used for draining residual water from the pipeline system and for cleaning the pipelines during the cold season. For example, the on / off valve 3 is a ball valve made of ABS and with a specification of DN80.

[0046] In some embodiments, the bottom of the valve chamber 4 has a drainage layer 9, the height of which is lower than that of the switching valve 3.

[0047] Specifically, such as Figure 4 As shown, a drainage layer 9 composed of sand and gravel pads is provided at the bottom of the second valve chamber 4. By setting the drainage layer 9, the water collected in the drainage well can be discharged more efficiently.

[0048] In some embodiments, the bottom of the support frame 10 has a water collection tray 13, and the outlet of the water collection tray 13 is connected to the valve chamber 4 via a pipe.

[0049] Specifically, such as Figure 3 As shown, the water collection tray 13 is located at the bottom of the support frame 10. There is a pipe connecting the outlet of the water collection tray 13 and the valve chamber 4. Water in the water collection tray 13 can be discharged to the valve chamber 4 through the pipe. In cold winter, the residual water in the inlet pipe 11 can be discharged.
