step 1: the height of the feeding arm (24) is adjusted through the hydraulic device (3) according to the fish type, so that the feeding arm is positioned above the water surface or in the water; the fish food which is well blended into mud shape is put into the middle material cavity (21) from the feeding port (211), the rotating rod (213) drives the material pressing blade (214) to rotate, the mud fish food is extruded outwards, and meanwhile, the inner mesh plate (28) rotates, so that the fish food enters the particle cavity (22) after being granulated through the inner mesh plate (28) and the outer mesh plate (23);
step 2: fish food particles in the particle cavity (22) enter the inner cylinder (241) under the driving of the flood dragon shaft (243), and enter a cavity between the inner cylinder (241) and the outer cylinder (242) through the first particle outlet holes (244);
and step 3: the first motor (250) drives the outer cylinder (242) to rotate, and in the rotating process of the outer cylinder (242), the plug head (247) and the permanent magnet (246) are repeatedly opposite to and staggered; when the pair of the fish feed is in positive synchronization, the permanent magnet (246) attracts the plug head (247) to move towards the permanent magnet (246), so that the second grain outlet hole (245) is leaked, the granular fish feed in the cavity between the inner cylinder (241) and the outer cylinder (242) is thrown out, and the permanent magnet (246) continuously stirs the granular fish feed to promote the granular fish feed to be thrown out; when the grain is staggered, the permanent magnet (246) cannot attract the plug head (247), and the plug head (247) blocks the second grain outlet hole (245) under the restoring action of the spring or the elastic rope; the process is repeated with the rotation interval of the outer cylinder (242);
and 4, step 4: and 3, driving the rotary disc (26) to rotate by the second motor (271) while the step 3 is carried out, so as to drive the feeding main body (2) to rotate slowly.
