Three storage troughs 24 are arranged on the lower side wall of the feeding rotating column 19. The three storage troughs 24 have different volumes, so different amounts of fertilizers can be fed. By presetting the positions of the storage troughs 24 on each feeding rotating column 19, that is, moving the required storage troughs 24 to the bottom of the feeding tube 18, the ratio of different fertilizers can be achieved, and the user can mix different fertilizers according to the actual growth conditions of the citrus seedlings. A first plug rod 25 is slidably inserted at one end of the unloading rotating column 19, and a pull rod 20 is fixedly connected to the other end of the unloading rotating column 19.

The mixing barrel 32 is provided with a mixing structure inside. The bottom of the mixing barrel 32 is provided with a blocking structure connected to the mixing structure. The mixing structure includes a third motor 31 fixed to the upper end of the discharge hopper 16. The output shaft of the third motor 31 penetrates the inside of the mixing barrel 32 and is fixed with a stirring shaft 35. A stirring rod 36 is fixed on the side wall of the stirring shaft 35. The blocking structure includes a sliding plug-in A second plug rod 39 at the lower end of the stirring shaft 35 has a blocking plate 37 located below the mixing barrel 32 fixedly sleeved on its side wall, and a plurality of convex strips 38 are fixed on the upper surface of the blocking plate 37.

[0023] When the fertilizing device of the present invention is used, the user first moves the material storage trough 24 on the material storage trough 19 according to the growth status of the citrus seedlings, and then pulls the handle 23 to move, selects the corresponding position of the material storage trough 24 on the material storage trough 19 and the material storage tube 18, operates the positions of multiple material storage troughs 19 according to the needs, and then starts the first motor 15 to drive the first plug rod 25 to rotate, and drives the material storage trough 24 to rotate through the first plug rod 25. With the rotation of the material storage trough 24, the material storage trough 24 can be rotated to the bottom of the material storage tube 18 to receive the fertilizer dropped from the material storage tube 18. Then, with the rotation of the material storage trough 19, the fertilizer inside the material storage trough 24 falls into the discharge hopper 16 again, and the multiple fertilizers discharged by the multiple material storage troughs 19 enter the mixing barrel 32 through the discharge hopper 16. Then, the third motor 31 is started to rotate, and the stirring shaft 35 is driven to rotate by the third motor 31, and the stirring shaft 35 drives the stirring rod 36 to stir and mix the fertilizers, so that the various fertilizers are mixed more evenly; Then the user pushes the bottom plate 1 toward the citrus seedlings through the push rod 3, and the citrus seedlings enter the inner side of the bottom plate 1 through the notch 17, and then starts the first electric telescopic rod 5 to extend, driving the two positioning plates 6 to clamp on the citrus seedlings, so that the bottom plate 1 can be positioned and fixed; Then start the second motor 27 to drive the two first gears 11 to rotate. Since the first gear 11 is meshed with the arc-shaped gear ring 9, the arc-shaped rotating plate 8 can be driven to rotate, and the device box 12 is driven to rotate around the citrus seedlings through the arc-shaped rotating plate 8. At the same time, the second electric telescopic rod 33 is started to extend, and the second plug rod 39 is driven to move downward through the connecting rod 34. The blocking plate 37 is driven downward by the second plug rod 39, so that the lower port of the mixing barrel 32 is opened, and the fertilizer in the mixing barrel 32 can leak out, so as to achieve fertilization of the citrus seedlings in a circle. At the same time, the stirring shaft 35 is rotated to drive the second plug rod 39 and the blocking plate 37 to rotate. When the blocking plate 37 rotates, the fertilizer leaking down can be broken up through the convex strips 38, so that the fertilizer is more evenly applied around the citrus seedlings.
