Depth-adjustable grape fertilizing device

The invention relates to the technical field of grape planting equipment, in particular to a depth-adjustable grape fertilizing device which comprises a fertilizing rack and walking wheels, a fertilizer box and a water tank are fixedly mounted at the top of the fertilizing rack, and a fertilizing device is arranged in the fertilizing rack and comprises a mixing mechanism and a spraying mechanism. The mixing mechanism comprises a first mixing box body, and a cleaning mechanism is arranged in the first mixing box body. The fertilizing device has the beneficial effects that the mounting frame is pushed to drive the sliding block to slide on the surface of the sliding rail, and meanwhile, the mounting frame drives the gear to rotate and move on the surface of the rack plate, so that the transverse position of the fertilizing pipe is changed, and when the fertilizing height needs to be changed, an asynchronous motor I is started, and an output shaft of the asynchronous motor I drives a transmission part to transmi
