The invention discloses a watering device for hole positioning cultivation of sweet potatoes. The water device comprises a pull rod, wherein the front end of the pull rod is movably connected with the middle of a
water diversion tube which is connected with a water receiving
pipe head, the lower side of the
water diversion tube is communicated with a water
nozzle, and two ends of the
water diversion tube are connected with a left
spoke wheel and a right
spoke wheel through bearings. By means of the
spoke wheel structure, wheel type movement is achieved, labor intensity is greatly reduced, one person can easily complete multi-
cave positioning watering and quickly move the device, labor cost is greatly reduced, and high efficiency on watering cultivation of the sweet potatoes is achieved. By means of spokes and feet on the spoke wheels of the watering device, accurate hole and position positioning can be performed, and cultivation
standardization of the sweet potatoes is achieved. The watering device for the hole positioning cultivation of the sweet potatoes can adjust line spacing, row spacing and
ridge height, meets needs of different cultivation dense and cultivation
modes, is wide in adaptability, simple and concise in structure, easy to operate and convenient to dismantle and carry, facilitates standard cultivation, and remarkably improves efficiency.
