AI Technical Summary
When using surface water, existing drip irrigation systems are prone to blockage of drip heads due to silt and sand impurities, which will affect the normal operation of the system. Since the greenhouse area is generally not large, farmers are unwilling to invest a lot of money to purchase large-scale filtration equipment, which leads to frequent replacement of drip heads, which increases costs.
A drip irrigation filter is designed, including a water inlet, a tank body, a tank lid, a water outlet and a pull-out basket. A filter layer is provided in the pull-out basket. The upper end of the filter layer is equipped with a movable rod. The movable rod is connected to the guide cylinder. The guide cylinder is fixed in the can lid. The upper end of the pull-out basket is fixed by a pressure plate, and a movable space is provided at the connection between the fixing plate and the movable rod. Under the action of water pressure, the pull-out basket and the filter layer produce a small floating, which accelerates the filtration of water flow.
The drip irrigation filter can effectively filter the silt and sand impurities in the surface water, is easy to replace, and is cheap to use. It is suitable for greenhouse farmers, reducing the risk of drip blockage and replacement frequency, and reducing operating costs.

Description
Technical Field
[0001] The utility model relates to the technical field of agricultural irrigation filtering equipment, in particular to a drip irrigation filter. Background Art
[0002] Drip irrigation is a commonly used method for water-saving irrigation in greenhouses. Simple drip irrigation not only requires less investment, but also saves water and fertilizers, and reduces various diseases and pests caused by excessive humidity in the greenhouse. The drip irrigation facilities mainly consist of dry ports, branch ports, capillary ports, drip heads, etc., and can directly drip water, fertilizers, air, and heat required by plants to the roots of plants, making the roots of crops developed. This irrigation method has uniform water irrigation, does not loosen or harden, and has good air permeability. Drip irrigation not only saves water and labor, but also can improve the yield and quality of vegetable production. However, most drip ports in greenhouses directly use surface water for drip irrigation. The surface water contains a large amount of sediment and organic substances, which is easy to cause clogging of drip heads. In severe cases, the entire system cannot work properly or even be scrapped. Drip irrigation has strict requirements for water quality and generally should be filtered. However, the area of greenhouses is generally not very large, and farmers will not invest a large amount of money to purchase large-scale filtering equipment. Therefore, drip heads need to be frequently replaced during use, resulting in cost waste. Summary of the Utility Model

The middle of the filter layer 6 is quartz sand filter material, and filter screens are provided on the upper and lower end faces. The quartz sand filter material has a low price and can effectively filter the sediment particles and some suspended substances contained in surface water. The filter layer 6 is located at the lower end of the lifting basket 5. A movable rod 7 is provided on the upper end face of the filter layer 6. The movable rod 7 is slidably connected to the guide cylinder 8. The movable rod 7 presses the filter layer 6 to make the filter layer have tightness and increase the filtering effect. The guide cylinder 8 is fixed to the tank cover 3 as a whole. The tank cover 3 is screwed to the tank body 2. A pressing plate 9 is provided on the upper end face of the lifting basket 5. The pressing plate 9 is slidably connected to the movable rod 7, so that the pressing plate 9 presses the lifting basket 5.

[0028] In a specific embodiment, as Figures 1 to 2 shown, the water inlet 1 is located at the upper end of the tank body 2, and the water inlet 1 is higher than the upper end face of the pressing plate 9.
[0029] Working principle of the drip irrigation filter of the utility model: Open the water inlet valve 13, and surface water enters the tank body 2 through the water inlet 1. A lifting basket 5 is arranged in the tank body 2. The upper end of the lifting basket 5 is lower than the water inlet 1. A rubber ring 502 is arranged on the outer ring of the lifting basket 5 to make the lifting basket closely combined with the cylinder wall, preventing surface water from directly entering the water outlet 4 without filtration. A filter layer 6 is arranged in the lifting basket 5. The middle of the filter layer 6 is quartz sand filter material, and filter nets are arranged on the upper and lower end faces. The quartz sand filter material has a low price and can effectively filter sediment particles and some suspended substances contained in surface water. The lifting basket 5 is made of stainless steel thin-walled pipe, with a light weight. A handle 501 is installed at the upper end, which is convenient for users to take out when replacing the filter layer 6. Filter holes are arranged at the bottom end of the lifting basket 5, and the filtered water flows into the water outlet 4 through the filter holes and is conveyed to the drip irrigation system.

The movable rod 7 is slidably connected to the guide cylinder 8. The guide cylinder 8 is fixed to the tank cover 3 as a whole. A pressing plate 9 is arranged on the upper end face of the lifting basket 5. The pressing plate 9 is slidably connected to the movable rod 7. Under the action of water pressure, the lifting basket 5 and the filter layer 6 will produce small floating, which can accelerate the filtration of water flow. After using for a period of time, the water flow of the drip irrigation slows down. Turn off the water inlet valve 13 and the water outlet valve 14. The tank cover 3 and the tank body 2 are connected by threads. Unscrew the tank cover in the middle and remove the tank cover 3. The guide cylinder 8 at the lower end of the tank cover 3 will take the movable rod 7 and the pressing plate 9 and remove them together. Hook the handle 501 on the lifting basket 5 with a hook, take it out, and replace the filter layer 6. When there is residual dirt on the inner wall of the tank body, the water inlet valve 13 and the sewage discharge valve 15 can be opened to clean the inner cavity of the tank body 2, and the dirt is discharged from the sewage outlet 10. After cleaning the tank body 2, close the sewage discharge valve 15. Replace the filter layer 6, place the lifting basket 5 into the tank 2, then screw the tank cover 3, the movable rod 7 and the pressing plate 9 together tightly with the tank body 2. The movable rod 7 and the pressing plate 9 press the lifting basket 5 and the filter layer 6. Open the water inlet valve 15 and the water outlet valve 16 to continue working. This structure is simple, convenient to replace, and has a low cost, which is suitable for greenhouse farmers to choose.
