The device for applying slow-release fertilizer for fresh corn planting according to claim 7, characterized in that: The rectangular seat (35) is provided with a rotation groove, the inner wall of the rotation groove is provided with an annular groove, the adjusting screw (37) is fixedly mounted with an annular seat, and the annular seat is rotationally connected to the annular groove.

9. The device for applying slow-release fertilizer for fresh corn planting according to claim 1, characterized in that: The synchronization mechanism comprises a sprocket wheel one (12) and a chain one (13); the rear ends of the driving shaft (7) and the rotating shaft (9) are both fixedly mounted with a sprocket wheel one (12); and the transmission sleeves on the two sprocket wheels one (12) are provided with the same chain one (13).

10. A method for applying slow-release fertilizer to fresh corn planting, characterized in that: The following steps are involved: S1: The slow-release fertilizer is placed in the storage box (5), the frame (1) is connected to the vehicle, and the hydraulic cylinder (18) is started. The hydraulic cylinder (18) can drive the driving seat (17) to move downward through the output shaft, and the driving seat (17) can drive the furrow opener (16) to move downward, so that the furrow opener (16) can be inserted into the corn field, and the frame (1) can be driven by the vehicle to move; S2. When the vehicle drives the frame (1) to move, the roller (3) can roll. With the cooperation of the sprocket (24) and the chain (25), the rotation of the roller (3) can drive the transmission shaft (23). At this time, the driving gear (30) and the driven gear (32) are meshed, and the transmission shaft (23) can drive the linkage shaft (26) to rotate synchronously. With the cooperation of the pulley (27) and the belt (28), the linkage shaft (26) can drive the rotating The rotating shaft (9) rotates, and the rotating shaft (9) can drive the material discharging seat (10) to rotate, and the slow-release fertilizer falls into the material discharging trough (11) on the material discharging seat (10). When the material discharging seat (10) rotates and the opening of the material discharging trough (11) is downward, the slow-release fertilizer in the material discharging trough (11) can fall into the material discharging hole (14), and the slow-release fertilizer can be transported to the soil of the corn field through the telescopic tube (15) and the furrow opener (16), thereby achieving the purpose of fertilization; S3. Through the cooperation of the sprocket wheel 1 (12) and the chain 1 (13), the rotation of the rotating shaft (9) can drive the driving shaft (7) to rotate, and the driving shaft (7) can drive the breaking rod (8) to rotate, and the breaking rod (8) can stir the slow-release fertilizer in the storage box (5), so as to prevent the slow-release fertilizer from agglomerating and blocking the discharge pipe (4); S4. By rotating the knob (38) and the adjusting screw (37), under the action of the threaded hole (36), the adjusting screw (37) can drive the rectangular seat (35) to move, the rectangular seat (35) can drive the moving sleeve (31) to move, and the moving sleeve (31) can drive the driven gear 1 (33) and the driven gear 2 (32) to move, so that the driven gear 2 (32) is separated from the driving gear 2 (30), and the driven gear 1 (33) is meshed with the driving gear 1 (29). At this time, the transmission shaft (23) can drive the linkage shaft (26) to accelerate the rotation, thereby increasing the rotation speed of the unloading seat (10) and adjusting the fertilizer application amount.
