[0038] A valve is provided inside the inclined tube 22. When the valve inside the inclined tube 22 is opened, the granular soil rolls down on the upper part of the inclined block 19 under the action of its own gravity, and then enters the bottom of the auxiliary box 20 through the inclined tube 22.

[0039] When the first rod 4 rotates, the vertical rod 35 is driven to rotate through the driving wheel 32, the synchronous belt 34 and the driven wheel 33, and then the vertical rod 35 drives the C-shaped rod 27 to rotate. When the C-shaped rod 27 rotates, it will drive the two push rods 30 to move, so that the push rods 30 drive the corresponding sliding plugs 29 to slide back and forth in a sealed manner inside the box body 28, and then intermittently draw in the nutrient repair liquid inside the annular box 31 and squeeze it to the atomizing nozzle 36 for spraying, and then the atomized nutrient repair liquid will form floating water mist inside the sub-box 20.

[0040] After the C-shaped rod 27 rotates, the C-shaped rod 27 will also drive the dragon blade shaft 23 to rotate. The dragon blades provided on the side walls of the dragon blade shaft 23 will continuously transport the granular soil at the bottom of the auxiliary box 20 upward, and then the granular soil is transported to the upper part of the annular plate 25. Then, because the side wall of the dragon blade shaft 23 is fixedly connected with a throwing plate 26, under the action of the throwing plate 26, the granular soil is quickly pushed to the outside, so that the granular soil is thrown off in a horizontal throwing motion on the upper part of the annular plate 25, and then the granular soil can be better combined with the nutrient repair liquid in an atomized state to complete the repair work of the granular soil.
