[0002] As a major corn consumer in the world, corn is grown on a large scale in my country. In the early stages of corn growth, regular fertilization is performed to ensure the growth of corn.

[0003] Existing fertilization devices often pile fertilizers at the roots of corn seedlings or sprinkle them around corn seedlings when fertilizing. The former easily causes excess nutrition to the seedlings, resulting in seedling burns, while the latter causes fertilizer nutrients to be unable to be fully absorbed by the corn seedlings, resulting in fertilizer waste. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fertilizing device for corn planting, comprising a fertilizer hopper, which is mounted on the rear of a tractor, a mounting frame mounted on the bottom side of the fertilizer hopper, a feed pipe rotatably mounted on the mounting frame, a discharge pipe mounted on the bottom side of the fertilizer hopper, and the bottom end of the discharge pipe is located inside the feed pipe, a barrel is mounted on the bottom side of the mounting frame, a material distribution cover seat is mounted on the middle part of the barrel through a support arm, the bottom end of the feed pipe is connected to the feed end of a screw conveyor, a discharge pipe is mounted on the discharge end of the screw conveyor, and the discharge pipe is located between the barrel and the material distribution cover seat.

[0007] Preferably, the side wall of the fertilizer hopper is installed with a side plate, the rear of the tractor is installed with a connecting seat, the top side of the connecting seat is installed with a pneumatic cylinder, and the telescopic end of the pneumatic cylinder passes through the connecting seat and is connected to the side plate.

[0008] Preferably, the feed pipe and the mounting frame are connected via a bearing, and external teeth are provided on the outside of the feed pipe.

[0009] Preferably, a motor is mounted on the mounting frame, a rotating gear is mounted on the output end of the motor, and the rotating gear is meshed with the external gear.

[0010] Preferably, the material distribution cover seat is a conical structure.

[0011] The beneficial effects of the utility model are as follows: the lifting and lowering of the material barrel and the material distribution cover seat are achieved through the pneumatic cylinder, which makes it convenient to cover the outside of the corn seedlings with the material distribution cover seat, and the motor drives the rotating teeth to rotate, cooperates with the meshing external teeth, and drives the feed pipe to rotate. At this time, the screw conveyor and the discharge pipe rotate with the feed pipe as the center of the circle. During the rotation process, the screw conveyor evenly fills the fertilizer in the fertilizer hopper through the discharge pipe to the space between the material barrel and the material distribution cover seat, the material barrel and the material distribution cover seat move up, and the fertilizer is automatically distributed in a circular shape on the outside of the corn seedlings, thereby achieving uniform fertilization around the corn seedlings.
