However, the fixing method using the fixing screws also requires the use of external tools, which is inconvenient for the later disassembly and replacement of the filter. For this reason, we provide a farmland water conservancy irrigation anti-blocking pipe. Utility Model Content

[0009] Furthermore, the inner depth of the first internal thread groove is the same as the distance between the filter screen and the left or right port of the T-tube.

[0010] Furthermore, two short rods are respectively disposed on the outer side wall of the top end of the limiting sleeve and are opposite to each other on the left and right sides.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When using the agricultural water conservancy irrigation anti-blocking pipe, the filter screen is abutted against one side end of the support strip, and the plug plate is inserted into the slot on the support strip, and then the clamping rod is inserted into the vertical through holes on the fixed cylinder, the plug plate and the support strip in sequence through the top block, and the bottom end of the clamping rod is flush with the lower surface of the support strip, and then the limiting sleeve can be fixed on the fixed cylinder through the threaded connection between the internal thread and the external thread. At this time, the plug plate is limited and fixed on the support strip by the clamping rod, and the filter screen can be installed inside the T-tube. The above steps can be reversed to remove the filter screen. The operation process is simple, no external tools are required, and the user is convenient to use, which improves work efficiency. Among them, the downward movement of the limiting sleeve will cause the top block to be pressed downward, thereby compressing the telescopic rod and the spring. When the limiting sleeve is separated from the fixed cylinder, the top block can be pushed out of the fixed cylinder by the elastic action of the spring through the telescopic rod. At this time, the user can remove the clamping rod from the T-tube by grabbing the top block, which improves the convenience of using the clamping rod.

[0013] 2. When using the farmland water conservancy irrigation anti-blocking pipe, the filter net can filter impurities in the water to prevent pipe blockage. By setting the internal thread groove, the T-tube can be connected to other water inlet pipes with threaded joints. BRIEF DESCRIPTION OF THE DRAWINGS
