[0002] At present, during the planting and cultivation process of corn, topdressing will be carried out on the corn seedlings depending on the actual situation. The main method is to bury granular fertilizers near the roots of the corn seedlings. In order to reduce the difficulty of operation and improve the efficiency of operation, technicians in related fields have developed some targeted devices, such as the patent document with application number 202321995360.0, which discloses "by fixing the sleeve at a specified position along the support frame, and then the operator steps on the foot pedal for leverage, and then pulls the push rod to drive the topdressing tube upward into the topdressing box to receive the granular fertilizer particles. After the granular fertilizer particles enter the topdressing tube, the push rod is pushed in the reverse direction to penetrate the tip of the lower end of the topdressing tube deep into the soil, and the granular fertilizer particles naturally fall into the soil."

[0029] Working principle:
[0030] Example 1
[0031] When it is necessary to topdress the corn, the handle bracket 8 can be held and the entire device can be moved to the specified position. Then, the entire device is made perpendicular to the ground, and the servo motor 3 is started. The output end of the servo motor 3 drives the spiral shaft 6 to rotate synchronously through the transmission shaft 5. Then, the entire device is moved down, and the rotating spiral shaft 6 is used to automatically drill holes in the soil layer near the roots of the corn. After completion, the entire device is moved up, the servo motor 3 is turned off, and then the electric push rod 72 is started. The output end of the electric push rod 72 drives the protective sleeve 71 to move downward synchronously, and then one end of the U-shaped rod 73 is separated from the clearance hole. The granular fertilizer inside the conical barrel 1 then enters the hole just processed on the ground through the clearance hole, so that the granular fertilizer is close to the roots of the corn, so that the corn can absorb it better.
[0032] Example 2
[0033] When the granular fertilizer used in the conical barrel 1 condenses in a humid working environment, the servo motor 3 can be started, and the output end of the servo motor 3 drives the spiral shaft 6, multiple first stirring shafts 9, and multiple second stirring shafts 10 to rotate synchronously through the transmission shaft 5. Then, the multiple first stirring shafts 9 and multiple second stirring shafts 10 are used to stir and disperse the granular fertilizer inside the conical barrel 1, thereby solving the condensation problem of the granular fertilizer.
