Farmland drainage pipe structure with filtering function

Abstract

The utility model discloses a farmland drainage pipeline structure with filter function belongs to drainage pipeline technical field, and its technical scheme main points include drainage pipeline body, the inside slide coupling of drainage pipeline body has filter equipment, the surface welding of drainage pipeline body has limited position mechanism, filter equipment adopts three jar progression formula filter, and the big aperture filter hole of left filter jar, the middle aperture filter hole of middle part and the small aperture filter hole of right side form gradient interception system, can realize separation to different particle size's impurity in farmland drainage, first, intercept straw, weed and other bulky impurities through big aperture filter hole, then, intercept gravel, rice hull and other medium particles by middle aperture filter hole, finally, filter silt and other fine suspended impurities through small aperture filter hole, cooperate the filter screen of filter hole inside, further promote the filtering precision, avoid the problem that single filter structure is easy to be blocked by impurity fast, make each level filter unit each play its own role.
