The invention discloses a 
lateral movement sprinkler water inlet bend rapid replacement rotation device which comprises a bend, a connecting piece, a water inlet 
pipe and a middle connecting piece. A second 
flange is fixedly welded to one side of the bend, a third 
flange is fixedly welded to the bottom of the bend, a first 
flange is fixedly welded to one side of the water inlet 
pipe, and the first flange and the second flange are fixedly connected through the middle connecting piece; and connecting pipes are arranged on the two sides of the middle connecting piece, and outer threads are arranged on the outer walls of the connecting pipes. According to the 
lateral movement sprinkler water inlet bend rapid replacement rotation device, the water inlet 
pipe is connected with a 
water source, the third flange is connected with an 
irrigation device, the bend and the water inlet pipe are fixedly connected through the middle connecting piece, and therefore the conveying effect is achieved; and a sealing ring is used for improving the leakproofness, during disassembling, fixing nuts are disassembled, the connecting pieces are taken down, the middle connecting piece is rotated, and then the bend and the water inlet pipe can be separated. The 
lateral movement sprinkler water inlet bend rapid replacement rotation device is reasonable in structure, relatively convenient to 
mount and demount and good in leakproofness, the working efficiency is effectively improved, and cost is saved.
