The working principle of the invention is as follows:

the two groups of modular feed boxes 10 are in threaded connection with the two groups of assembling plates 11 through the connecting plates 26 on one side of each modular feed box 10, the spline pipes 97 in the two groups of assembling boxes 9 are respectively embedded into the second connecting ends 16 of the connecting shafts 13 in the two groups of modular feed boxes 10, then the buckles 18 are closed, the spline grooves of the buckles 18 are clamped and connected to the outer sides of the spline pipes 97, the first bolt plates 17 and the second bolt plates 20 are in threaded connection and fixed through bolts, then the modular feed boxes 10 are assembled with the two groups of modular feed boxes 10, in the assembling process, the clamping blocks 28 of the modular feed boxes 10 which are not installed are embedded into the clamping grooves 27 of the installed modular feed boxes 10, the connecting plates 26 adjacent to the two groups of modular feed boxes 10 are fixed through bolts, then the steps are repeated, the first connecting ends 15 of the modular feed boxes 10 are sequentially installed inside the spline grooves of the second connecting ends 16 in the adjacent modular feed boxes 10, then the buckles 18 are used for folding and reinforcing, then the feeding device is placed on the upper side of the track 1 after the assembly is finished, then the fourth air cylinder 92 is started, and each group of modularized feed boxes 10 are adjusted;

the driving box 2 is started to drive the feeding device to move back and forth along the track 1, the driving motor 93 is started, and the driving motor 93 drives the rotating pipe 94 and the spline pipe 97 to rotate through the second synchronous belt 95, so that the connecting shafts 13 in the modular feed boxes 10 are driven to rotate;

the connecting shaft 13 rotates to drive the driven gear 23 of each group of assembly frames 22 to rotate around the gear ring 21, the driven gear 23 rotates under the action of the gear ring 21, and the first synchronous belt 25 drives each group of stirring frames 24 to rotate to stir the feed;

opening an electromagnetic valve inside the discharge pipe 12 to throw the feed into the intervals of the rice in each row;

meanwhile, the first cylinder 6 and the second cylinder 7 are started, the water outlet of the connecting hose 4 is immersed into the lower side of the water surface in the rice field, and the air pump 3 is started to supply oxygen to the water in the rice field.
