[0015] (ii) In the present application, irrigation water enters through the top of the filter cartridge, and then is filtered through the inclined filter screen, so that impurities such as branches, leaves, mud and sand in the irrigation water are blocked, and fall into the mesh storage cartridge along the inclined filter screen.

[0016] (III) In the present application, the rotation of the output end of the driving motor drives the sector gear to rotate, and the sector gear meshes with the No. 1 tooth, so that the sector gear drives the No. 1 tooth to move, and the No. 1 tooth drives the measuring liquid plate to move through the linkage frame, so that the areas with different through-hole diameters on the measuring liquid plate fit with the liquid pipe to control the water delivery rate in the water storage tank, and the No. 1 tooth will fall off when the sector gear rotates continuously. At this time, the sector gear meshes with the No. 2 tooth, so that the measuring liquid plate can move in the opposite direction, so that the diameter of the delivery port of the liquid pipe can be changed and restored, and the water delivery volume can be adjusted automatically according to the planting conditions of crops to achieve a good water-saving effect.

[0017] (IV) In the present application, when irrigation water is input, the irrigation water will impact the stamping plate, and the stamping plate is forced to drive the reciprocating rod to rotate. At this time, the torsion spring is stressed and forces the reciprocating rod to reset, and the reciprocating rod drives the connecting gear to rotate, so that the connecting gear drives the sliding rod to slide in the sliding groove through the outer gear teeth, so that the inclined mesh cylinder can shake up and down, which not only makes the filtering effect of the inclined filter better and avoids blockage, but also the impurities above the inclined filter can be shaken off into the mesh storage cylinder, so that the removal of impurities is more thorough.
