[0028] First baffles 15 are fixed on the left side wall of the hopper 1 on the front and back sides corresponding to the discharge opening; when in use, after the guide plate 23 swings to the left, the first baffles 15 block the corn seeds from running out through the gap between the guide plate 23 and the discharge opening. Second baffles 19 are fixed on the front and back side walls of the guide plate 23 corresponding to the bottom of the hopper 1. After the corn seeds slide out along the guide plate 23, the front and back two second baffles 19 can prevent the corn seeds from running out to the front and back sides after sliding out;

[0029] In actual use: the worker pushes the handle 11 to rotate the seeding wheel, the seeding wheel rotates counterclockwise and moves to the left, in the process of moving, the seeding bucket 9 passes the guide plate 23 and collides with the adjusting plate 18, which drives the guide plate 23 to swing to the left, the guide plate 23 swings to the left, the discharge port of the hopper 1 opens a little, the corn seeds inside slide out along the guide plate 23 and enter the seeding bucket 9 below, and then enter the storage cavity of the U-shaped storage plate 7. The seeding wheel continues to rotate, the corn seeds in the storage cavity slide down along the opening of the U-shaped storage plate 7, and then fall into the seedling hole of the farmland; accordingly, the blocking block 8 can be fixed on the inner side of the U-shaped storage plate 7, which forms a certain blockage during the falling of the corn seeds, so that the opening of the U-shaped storage plate 7 is inclined to be close to the vertical state, and the corn seeds cannot fall down.

[0030] When adjusting the discharge amount of corn seeds, the adjusting plate 18 is adjusted to stretch or shrink along the length direction of the guide plate 23, the collision area between the adjusting plate 18 and the seeding bucket 9 is controlled, the more the area of the seeding bucket 9 colliding on the adjusting plate 18, the greater the swing of the guide plate 23, and the larger the opening of the discharge port, the more the corn seeds falling at one time, and vice versa, so as to control the amount of corn seeds sowing. The specific situation is adjusted according to the planting land and the variety of seeds and other factors. In addition to corn seeds, the embodiment can also sow some other seeds, such as peanut and other granular seeds.
