Soil treatment irrigation device with nozzles convenient to replace

Abstract

The invention relates to a soil treatment irrigation device with nozzles convenient to replace. The irrigation device comprises a bottom plate, an irrigation device body is fixed to the top end of the bottom plate through a supporting column, a filter screen is fixed to an inner cavity of the irrigation device body, a rotating shaft is rotatably connected to the inner cavity of the irrigation device body, and a fixing block is fixed to the tail end of the rotating shaft; a threaded groove is formed in the surface of the bottom end of the fixing block, a threaded rod is in threaded connection with the inner side of the threaded groove, a fixing frame is fixed to the bottom end of the threaded rod, and fixing springs which are evenly distributed are fixed to the inner side of the fixing frame. Through the arrangement of a scraper, the rotating shaft can scrape sand and stones on the filter screen while rotating; through the arrangement of a cleaning brush, filtering holes of the filter screen can be cleaned, and normal filtering of the filter screen is further guaranteed; and through the arrangement of a clamping block and a fixing bolt, the scraper and the cleaning brush can be conveniently and rapidly disassembled, and then the working quality and efficiency of the device are improved.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to an irrigation device for soil treatment which is convenient for replacing nozzles. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three types: physical, chemical and biological. method, irrigation devices are needed in soil remediation work; [0003] However, there are still some disadvantages in the existing irrigation device for soil treatment that is easy to replace the nozzle. Because the water in the device will have a lot of sand and gravel, after a long period of accumulation, agglomeration may occur, and then it is easy to cause the problem of blockage; After scraping off the agglomerated sand and gr...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an irrigation device for soil treatment that is easy to replace the nozzle, which can solve the problem that the water in the device will have a lot of sand and gravel, which may agglomerate after a long time of accumulation, and then easily In addition, after scraping the agglomerated sand and gravel, there may still be a small amount of fine sand and gravel in the filter holes on the filter screen, which cannot be removed; there is also the problem that the scraper and the cleaning brush have been in contact with the sand and gravel for a long time. Frictional contact can easily lead to different degrees of wear on the surface, and there is a problem that it is inconvenient to replace
