Water and fertilizer integrated planting device for sweet potatoes

The invention relates to the technical field of agricultural machinery, in particular to a water and fertilizer integrated planting device for sweet potatoes. According to the technical scheme, the device comprises a planting assembly placement frame and a lower guide gear rotationally installed in the planting assembly placement frame, and further comprises an upper positioning gear, the interior of the upper positioning gear is connected with the lower positioning gear in a meshed mode, and the interior of the lower positioning gear is rotationally connected with an insertion rotating rod. The arc-shaped surface of the arc-shaped storage block is inserted into the deep position of the land to open the circle of the land, the arc-shaped storage block turns up a part of the land, and the positioning push plate turns out the turned-up land, so that soil ploughing before planting in the later period is facilitated, planting integration is improved, meanwhile, a land worker can conduct ploughing according to the
