Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation equipment, in particular to farmland drip irrigation equipment. Background Art

[0002] Drip irrigation is one of the most water-saving irrigation technologies for farmland irrigation so far. Drip irrigation is a method of irrigation in which water with a certain pressure is filtered and dripped slowly and evenly into the soil near the roots of plants in the form of water drops through a pipe network and an outlet pipe (drip irrigation belt) or a dripper. However, due to the slow flow of water, when the intensity of solar radiation is high, the temperature of the drip irrigation pipe rises and heats the water, especially the drainage pipe that leads the drip irrigation belt to the roots of the planted trees. The small diameter of the drainage pipe leads to a low total amount of water stored in the pipe, and the temperature easily rises under the sun, which eventually leads to the water temperature of the drip irrigation to the plants being too high.

[0003] To solve the above problems, a utility model patent document with announcement number CN214961621U discloses a farmland drip irrigation system, including a water pump, a drip irrigation pipe and a drainage pipe, wherein the water pump is connected to the drip irrigation pipe, the drip irrigation pipe is a flexible pipe, and the drip irrigation pipe is arranged on the side of the plant, the upper end of the drip irrigation pipe is provided with a plurality of first water outlet holes, the drainage pipe includes a plug, a drainage strip and a top cover, the lower part of the plug is detachably connected to the first water outlet hole, the upper part of the plug is provided with a second water outlet hole, the plug above the second water outlet hole is provided with the drainage strip, the bottom of the drainage strip is provided with a drainage groove, and the top of the plug is provided with the top cover. The utility model provides a farmland drip irrigation system, the drainage pipe is semi-open, and the temperature is reduced by evaporation of water to avoid excessively high water temperature for drip irrigation to the plant.

[0004] However, it is mainly through setting the drainage groove 9 downward that the water in the drainage groove 9 can evaporate, and the heat can be taken away by evaporation, thereby preventing the water temperature from rising due to sunlight during drip irrigation and scalding the plants.

[0005] This method significantly increases the water consumption of the drip irrigation device, which is not conducive to the conservation of water resources and needs to be improved. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] Reference Figure 1-5 The utility model farmland drip irrigation equipment includes an external water pipe 2 and an internal water pipe 6, and is characterized in that one end of the internal water pipe 6 is connected to the first water pump 5, the internal water pipe 6 is located on the inner side of the external water pipe 2, one end of the internal water pipe 6 is connected to the main internal water pipe 4, and a drip irrigation insert 3 is arranged on the internal water pipe 6, and the drip irrigation insert 3 passes through the external water pipe 2.

[0029] The lengths of the external water pipe 2 and the internal water pipe 6 are selected according to actual needs. The external water pipe 2 can wrap the internal water pipe 6 on the inside to block sunlight. The inner wall size of the external water pipe 2 can be selected to be larger than the outer wall size of the internal water pipe 6, so that there is a certain distance between the external water pipe 2 and the internal water pipe 6.

[0030] The outer water pipe 2 and the inner water pipe 6 are laid on one side of the plant. The inner water pipe 6 is located in the shadow inside the outer water pipe 2, which can effectively avoid the temperature increase caused by direct sunlight, thereby avoiding the temperature increase of the drip irrigation water in the inner water pipe 6, which is beneficial to protecting the plant seedlings from scalding.

[0031] The device further comprises a main outer water pipe 1 and a main inner water pipe 4 . The main inner water pipe 4 is located inside the main outer water pipe 1 . One end of the branch inner water pipe 6 is connected to the main inner water pipe 4 .

[0032] When in use, the main outer water pipe 1 and the main inner water pipe 4 are laid along the road in the farmland, and the outer water pipe 2 and the inner water pipe 6 are laid along the plants, and the laying method is more reasonable.

[0033] One end of the branch external water pipe 2 close to the main external water pipe 1 is communicated with the main external water pipe 1 .

[0034] The external water pipe 2 is connected to the main external water pipe 1 as a whole, which is convenient for arrangement, storage or deployment.

[0035] One end of the main external water pipe 1 is connected to a wind source (not shown in the figure).

[0036] The wind source can be a blower, Roots blower or other equipment, which is used to drive the air flow in the space between the main outer water pipe 1 and the main inner water pipe 4, and between the branch outer water pipe 2 and the branch inner water pipe 6. The airflow flows out from one end of the principle wind source, reducing the heat on the main outer water pipe 1 and the branch outer water pipe 2 from being transferred to the main inner water pipe 4 and the branch inner water pipe 6 through the air.

[0037] Example 2

[0038] The difference between this embodiment and the first embodiment of the utility model for farmland drip irrigation equipment is that one end of the main external water pipe 1 is connected to the second water pump (not shown in the figure).

[0039] The difference between this embodiment and embodiment 1 is that a second water pump is used instead of a wind source. Compared with a wind source, a water pump is a commonly used agricultural equipment, which is easier to obtain, and is more conducive to blocking the heat exchange between the main inner water pipe 4, the branch inner water pipe 6 and the external environment through water flow.

[0040] In this embodiment, the end of the main external water pipe 1 and the branch external water pipe 2 away from the second water pump can be connected to a water reservoir or a water tank, or can be connected to the water source where the first water pump is located or other water sources to avoid wasting water resources.

[0041] The water source is a pond, a pool, a canal, etc. near the farmland. Of course, filtering equipment can be added at the water source as needed, and the filtered drip irrigation water enters the main inner water pipe 4 from the first water pump.

[0042] Example 3

[0043] The utility model is a farmland drip irrigation device, and the difference between this embodiment and other embodiments is that the ends of the main external water pipe 1 and the branch external water pipe 2 away from the first water pump 5 are closed structures, and a through hole is provided on the branch internal water pipe 6, and the branch internal water pipe 6 is connected with the branch external water pipe 2 through the through hole.

[0044] A part of the drip irrigation water in the inner water pipe 6 drips into the roots of the plants through the drip irrigation tube 3, and the other part flows into the outer water pipe 2 from the through hole, and then flows into the main outer water pipe 1. The end of the main outer water pipe 1 close to the first water pump is an open structure, and a water tank can be placed at the opening, or the opening can be directly placed in the water source where the first water pump is located, so as to recycle water resources and avoid waste of resources.

[0045] The through hole is located at one end of the branch inner water pipe 6 away from the main inner water pipe 4 , and an elastic baffle 7 is arranged in the through hole, and one end of the elastic baffle 7 is connected to the inner wall of the through hole.

[0046] The elastic baffle 7 can be made of a rubber sheet, a silicone sheet or a spring sheet. The function of the elastic baffle 7 is that after the water in the inner water pipe 6 reaches a certain water pressure, the water pressure causes the elastic baffle 7 to elastically deform, and the water flow can flush the elastic baffle 7 and then flow back, so that the water pressure in the inner water pipe 6 meets the drip irrigation requirements.

[0047] The main inner water pipe 4 is located at the inner bottom of the main outer water pipe 1 , and the branch inner water pipe 6 is located at the inner bottom of the branch outer water pipe 2 .

[0048] Among them, the drip irrigation insert 3 is also located at the bottom of the branch inner water pipe 6. When the main outer water pipe 1, the branch outer water pipe 2, the main inner water pipe 4, and the branch inner water pipe 6 are laid on the ground, the main outer water pipe 1 and the branch outer water pipe 2 are mainly exposed to sunlight in the upper half, while the main inner water pipe 4 located at the inner bottom of the main outer water pipe 1 and the branch inner water pipe 6 located at the inner bottom of the branch outer water pipe 2 can be away from the exposed part, further reducing the influence of sunlight on the main inner water pipe 4 and the branch inner water pipe 6, and avoiding the increase of the temperature of the drip irrigation water.

[0049] Working principle: Before use, lay the main external water pipe 1 along the road in the farmland, lay the external water pipe 2 on one side of the plant, insert the drip irrigation tube into the root of the plant, put the first water pump 5 into the water source, and also put the opening of the main external water pipe 1 into the first water source.

[0050] When in use, the first water pump 5 pumps the drip irrigation water into the main inner water pipe 4, and then enters the branch inner water pipe 6. Then part of the water drips into the root of the plant through the drip irrigation tube 3, and the other part of the drip irrigation water squeezes the elastic baffle 7, flows back from the through hole into the branch outer water pipe 2, and then flows into the main outer water pipe 1, and finally flows back to the water source from the opening of the main outer water pipe 1.
