[0005] A guide hopper is arranged directly below the nozzle, and the guide hopper is formed with a guide inlet end capable of covering the sputtering area of ​​the nozzle;

[0006] A guide pipe has one end connected to the guide outlet end of the guide bucket, and the other end of the guide pipe is configured to be fixed to the seedling bed. A plurality of guide holes are opened on the side wall of the guide pipe.

[0007] Preferably, it also includes:

[0008] A fork bar is fixed to one end of the guide tube away from the guide bucket, and the tip of the fork bar is distributed in a vertical downward direction.

[0009] Preferably, it also includes:

[0010] A binding rope, a column head is fixedly connected to the top end of the fork, the column head is slidably fitted in the guide tube, the binding rope is located in the area outside the guide tube corresponding to the column head, and when the binding rope is wound around the guide tube, the column head is against the inner wall surface of the guide tube.

[0011] Preferably, the guide scoop is a conical structure, the end of the guide scoop with a larger diameter faces the nozzle, and the end of the guide scoop with a smaller diameter is connected to the guide pipe.

[0012] Preferably, a plurality of the guide holes are arranged on the guide tube at equal intervals from top to bottom in the circumferential direction.

[0013] Preferably, the flow guide pipe is a PVC pipe.

[0014] Compared with the prior art, the utility model has the following advantages and technical effects:

[0015] By taking over the splashing area of ​​the nozzle corresponding to the diversion bucket and covering the splashing area of ​​the nozzle with the guide inlet end, the water flow is prevented from falling directly on the seedling bed, and the splashing erosion of the seedling bed directly below is reduced. At the same time, the diversion pipe is used to guide the received water flow, and the diversion holes opened on its side wall surface reduce the positive impact force of the water flow on the seedling bed, so as to replenish water for the seedling bed while reducing the splashing erosion of the seedling bed.
