Efficient filter for automatic irrigation system

Abstract

The invention discloses an efficient filter for an automatic irrigation system. The efficient filter comprises a filter body, wherein filter screens are distributed in the filter body; the filter bodyis provided with a body cover from the side surface; three filter screen support grooves are formed in the filter body from top to bottom; correspondingly, a fine filtering layer filter screen, an intermediate filtering layer filter screen and a coarse filtering layer filter screen are sequentially and detachably distributed from top to bottom, wherein the hole diameter of the fine filtering layer filter screen, the intermediate filtering layer filter screen and the coarse filtering layer filter screen is sequentially increased; the water inlet direction of the filter body is from bottom to top. The efficient filter has the advantages that the filtering is efficient; the blockage cannot easily occur; the filter screen replacement is convenient; the three-stage filtering is used; the automatic irrigation system cannot easily generate the blockage; the use effect is good.

Description

technical field [0001] The invention relates to the technical field of agricultural automatic irrigation, in particular to a high-efficiency filter used in an automatic irrigation system. Background technique [0002] At present, with the gradual popularization of smart agriculture, automatic irrigation generally adopts the method of spraying or drip irrigation. However, since agricultural irrigation water generally has many impurities in the water, it is easy to cause blockage when it is directly applied to the automatic irrigation system. Therefore, it needs to be filtered first. Into the automatic irrigation system, but the current filter is not only costly, but also has low filtration efficiency. [0003] The disclosure of the above background technical content is only used to assist in understanding the concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application. If there is no clear evidence th...
