The present invention relates to a filtering apparatus for filtering a foreign matter contained in water and using a filter for supplying agricultural water to a crop in a more clean state, Unlike the previous one, which was difficult to clean the foreign matter after dismantling all the foreign substances, the foreign matter was automatically removed quickly and simply by applying the hydraulic pressure in the direction. Therefore, The present invention relates to a new high-efficiency foreign substance removing means which can contribute greatly to the life of the motor and the efficiency of the filtering operation.

In many cases, agricultural crops such as rivers, ditches, rivers, nails, agricultural or other aqueducts and groundwater are pumped up and fed to crops for the purpose of good growth and cultivation of crops.

However, since the above-mentioned agricultural water is often muddy water as well as various kinds of dust or sand particles of a certain thickness, if the puddling water is pumped,

Particularly, there is a disadvantage that sand grains are clogged in water spray nozzles, sprinkler nozzles, pesticide spray nozzles and other water spray nozzles for drip cultivation and inconvenience or inability to use.

In recent years, the use of agricultural water filters that can properly filter sludge at the end of a water pipeline has become commonplace.

1, a water inlet 110 is formed at one end of the upper portion of the agricultural filter, a water outlet 120 is formed at the other end thereof, and an auxiliary water outlet 130) and an upper filter case (100) having a filter assembly coupling part (140) formed inside the upper end thereof;

A spiral shape is formed on the outer side of the upper filter case 100 from the upper side to a lower side so as to be able to move to the lower filter assembly 400 in a state where a strong vortex is generated and the water flows into the inner side;

A lower filtration tube 200 having a predetermined space inside the upper filtration tube 100 and a clean groove 300 required for internal cleaning is coupled to the lower end of the upper filtration tube 100.

In particular, the filter assembly 400, after multiple filter elements 20 are inserted,

And a bending thread screw 142 having a gentle bending shape at its upper portion is formed on the upper portion of the upper portion of the lower portion of the body 110. A cap coupling male thread 412 is formed on the lower portion, And a filter multi-stage assembly frame 410 having a latching protrusion 413 on the inner side thereof;

In the filter multi-stage assembly frame 410, a stop engaging portion 421 corresponding to the engaging protrusion 413 is formed on the upper side and has a substantially "+" type skeleton, and an intermediate intermediate through hole 422 is formed And a slide extension member 420 having a piece fastening groove 423 formed at a lower end thereof;

A hole is formed in the same shape as a thin disk plate of a certain diameter to form a washer-like shape as a whole,

Since a ring-shaped band having a constant width is formed around the circumference of the ring-shaped circle, and filter grooves engraved at a predetermined depth are formed on the upper surface or the lower surface of the ring-shaped band so that when a plurality of filters are closely adhered to each other, Are passed, but foreign substances of a size larger than that can be filtered out.

However, when the filter is used for a certain period of time, foreign matter grains stick to the outside of the filter, and a large number of foreign substances are trapped in the filter grooves between the single filters. When this phenomenon accumulates, This causes the water supply to be substantially difficult and causes a failure due to a large load applied to the motor as a driving source of the pump. Therefore, when a certain usage period is reached, a large amount of water It is necessary that the filter body cleaning operation for collecting the foreign matters of the filter body is performed.

Meanwhile, the conventional filter assembly coupling structure has a structure in which a plurality of single-layer filters are closely adhered to each other by fastening the multi-stage assembled filters tightly with screws using a filter-supporting cap located at the lower portion,
