Anti-blocking pipeline for farmland irrigation

Abstract

The invention discloses an anti-blocking pipeline for farmland irrigation. The anti-blocking pipeline comprises a pipe body, a piston bush, a first electromagnetic valve, a filter screen plate and a fixed baffle. The piston bush is inserted in the pipe body and capable of sliding forwards and backwards in the same; the piston bush is provided with a through hole. The first electromagnetic valve is arranged in the through hole and used for controlling open and close of the through hole. The filter screen plate is inserted in the pipe body and capable of sliding forwards and backwards in the same; the filter screen plate is fixedly connected with the piston bush and is provided with a plurality of filter holes. The fixed baffle is of a hollow-out structure and is fixedly arranged in the pipe body and above the filter screen plate. A spring is arranged between the fixed baffle and the filter screen plate. A plurality of clearing rods, corresponding to filter holes in the filter screen plate, are arranged on the back of the fixed baffle protrudingly; the diameter of the clearing rods is smaller than that of the filter holes. The anti-blocking pipeline for farmland irrigation has the advantages that blocking of the pipeline for farmland irrigation can be prevented effectively automatically, the filter screen plate can be cleaned in time automatically, and thus both time and labor are saved.

Description

technical field [0001] The invention relates to the field of farmland water conservancy irrigation, in particular to an anti-blocking pipeline for farmland water conservancy irrigation. Background technique [0002] In the process of farmland water conservancy irrigation, it is often necessary to use pipelines to lead water to the fields that need to be irrigated, which is a very efficient irrigation method. The existing pipeline needs to be equipped with a filter device, but if the dirt intercepted by the filter device is not cleaned in time, the pipeline will be blocked, and the staff needs to take out the filter device for cleaning during the cleaning process, and the whole process is time-consuming and laborious. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the p...
