Description

Technical Field

[0001] The present application relates to the technical field of agricultural irrigation, and more specifically, to a high-efficiency filter device for farmland irrigation. Background Art

[0002] In agricultural production activities, in order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to carry out appropriate and reasonable irrigation according to the water demand characteristics, growth stage, climate, and soil conditions of the plants. Since there may be impurities such as aquatic plants and garbage in the irrigation water source, in order to prevent the water source input end from being blocked during the irrigation process, it is necessary to set a filtering device in the irrigation equipment. The patent document with the prior art publication number CN215074462U provides a farmland water conservancy water-saving irrigation mesh filter. The device can centrifuge the liquid inside the filter net by setting a rotating rod and a filter net, thereby achieving high-efficiency filtration of the liquid, thereby greatly improving the practical performance of the device. By setting a rotating rod, a stirring rod, a motor, a first gear, and a second gear, the water body and the nutrient solution entering the filter cylinder can be fully stirred, so that the water and fertilizer are dissolved more fully.

[0003] In view of the above-mentioned related technologies, the inventor believes that although the rotating filter can separate water from impurities, the impurities will gradually accumulate in the filter, resulting in low filtration efficiency of the filter, thus affecting the filtration use. Therefore, we propose a high-efficiency filter device for farmland irrigation. Utility Model Content

The positioning rod A and the positioning hole A cooperate to increase the stability of the connection between the filter plate and the connecting plate. The quick-release design between the filter plate and the connecting plate makes it easy to remove the filter plate for cleaning, thereby improving maintenance convenience.
