Description

Technical Field

[0001] This utility model relates to the structure of farmland irrigation equipment, specifically an irrigation device for farmland. Background Technology

[0002] Farmland irrigation refers to agricultural measures that use artificial facilities to deliver water to farmland to meet the water requirements of crops during their growth and development. It is an important means of improving agricultural production conditions and increasing crop yield and quality. Especially in areas with insufficient or uneven rainfall, farmland irrigation plays a decisive role in agricultural production.

[0003] In current irrigation technologies, drip irrigation is generally used to ensure water conservation. However, drip irrigation generally has high requirements for water quality because larger particles and long-term accumulation can clog the drip irrigation inlets. Nowadays, river water or canal water is often used for irrigation, but canal water contains more impurities, and direct extraction cannot meet the needs of drip irrigation. Utility Model Content

The partition plate is equipped with a filter cloth cover screen cylinder below the through holes. The second water pump is equipped with a second water pumping pipe that extends to the top of the partition plate.

[0007] Furthermore, the end of the first water pump is equipped with an external filter screen, which can coarsely filter some larger debris and prevent larger debris from being pumped in.

[0008] Furthermore, a liquid level sensor is installed above the partition plate inside the filter chamber to sense the liquid level of the filtered water inside.

[0009] Furthermore, the bottom of the inner cylinder structure is provided with a first drain valve pipe extending to the outside, and the bottom of the filter chamber is provided with a second drain valve pipe located outside the inner cylinder structure, to facilitate the discharge of filtered materials.

The end of the air outlet pipe is equipped with an air distribution ring pipe, and the bottom of the air distribution ring pipe is equipped with an air jet pipe aligned with the filter cloth cover cylinder, which can periodically clean the filter cloth cover cylinder and prevent sludge from adhering.

[0011] The advantages of this agricultural irrigation device compared with the prior art are as follows: This device, through its integrated design and multi-stage filtration of river water, can prevent fine particles and sludge from entering the irrigation system of the farmland, thereby preventing fine particles and sludge from clogging the drip irrigation inlet.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-4 An irrigation device for farmland includes a main body 1, a first water pump 4, and a second water pump 14. The first water pump 4 is provided with a first pumping pipe 5 extending to the outside for drawing river water. The end of the first pumping pipe 5 is provided with an external filter screen 6. The second water pump 14 is provided with an outlet pipe 16 extending to the outside for irrigation. A controller cavity 22 is provided on one side of the main body 1. The above structure is the basic equipment structure of a conventional irrigation system. The controller cavity 22 is generally equipped with a controller to facilitate the automatic control of electrical components in the equipment. This is a common circuit setting, so it will not be described in detail.

[0019] The main body 1 of the device is provided with a filter chamber 2, and an inner cylinder structure 3 is provided in the middle of the filter chamber 2. A partition plate 10 is provided in the middle of the filter chamber 2 to wrap the outer side of the inner cylinder structure 3. The first water pump 4 is equipped with a water guide pipe 7 that communicates with the interior of the inner cylinder structure 3. The inner cylinder structure 3 is equipped with a filter screen cylinder 11 below the partition plate 10. The mesh diameter of the filter screen cylinder 11 is set according to the local water quality in the river or canal, which can ensure that larger sludge particles can be filtered. The partition plate 10 is equipped with multiple through holes 12. The partition plate 10 is equipped with a filter cloth cover cylinder 13 below the through holes 12. The filter cloth cover cylinder 13 includes an internal support cylinder and an externally attached filter cloth cover, which can filter fine sludge impurities and ensure that the water entering the irrigation system remains pure. The second water pump 14 is equipped with a second water pumping pipe 15 that extends above the partition plate 10.
