Efficient farmland irrigation device

The utility model discloses an efficient farmland irrigation device, which relates to the technical field of agricultural irrigation and comprises a bottom plate, a supporting seat is fixedly mounted at the top of the bottom plate, a lifting mechanism is fixedly mounted at the top of the supporting seat, a top tray is fixedly mounted at the top of the lifting mechanism, and connecting water pipes are fixedly mounted at the top of the top tray at equal intervals. By adopting the structure, the limiting clamping blocks press the limiting springs to contract through the contact of the inclined surfaces of the limiting clamping blocks, the outer socket can be inserted into the inner side of the inner sleeve seat after the limiting springs contract, and when the limiting clamping blocks are in contact with the limiting grooves, the limiting springs can reset to drive the limiting clamping blocks to be inserted into the limiting grooves, so that the outer socket can be inserted into the inner sleeve seat.
