Several convex teeth on the digging wheel will dig the cultivated land to realize the digging action. When the toggle gear rotates, its gear teeth will squeeze the sealing mechanism to release the blocking of the discharge port at the bottom of the hopper. The seeds in the hopper will fall into the feed pipe through the discharge port. When the gear teeth are out of the sealing mechanism, under the action of the spring, the sealing mechanism will reset and move to realize the blocking of the discharge port at the bottom of the hopper again.

[0023] Through the design of the blocking mechanism, under normal circumstances, the guide rod and the sliding cylinder are in an elongated state under the push of the spring, and are not retracted from each other, and the blocking plate blocks the discharge port at the bottom of the hopper to achieve blocking of the discharge port, isolating the connection between the discharge port and the top opening of the feed pipe. When the linkage mechanism is operating, the gear teeth of the toggle gear rotate to squeeze the vertical section of the toggle blocking plate, thereby pushing the blocking plate to move horizontally to leak out of the discharge port at the bottom of the hopper, and the seeds in the hopper will fall into the feed pipe through the discharge port. The blocking plate moves linearly and squeezes the spring under the action of the guide rod and the sliding cylinder. When the gear teeth disengage from the blocking plate, under the action of the spring, the blocking plate resets and moves to block the discharge port at the bottom of the hopper again.

[0024] Through the design of the connecting mechanism, the connecting sleeve in the middle of the excavating wheel is sleeved on the rotating shaft 1, and then the connecting sleeve is rotated to make the connecting sleeve threadedly connected to the end of the rotating shaft 1. After the connection is fixed, the outer bolt hole 1 and the outer bolt hole 2 on the connecting sleeve are respectively matched with the inner threaded hole 1 on the connecting shaft and the inner bolt hole 2 on the rotating shaft 1. Subsequently, the outer bolt hole 1 and the inner threaded hole 1 as well as the outer bolt hole 2 and the inner bolt hole 2 are fixed together by the connecting bolt 1 and the connecting bolt 2, thereby fixing the connecting shaft and the rotating shaft 1 on both sides together to form a whole.

7. A corn seed breeding and sowing device according to claim 5, characterized in that: An annular sliding groove (30) is provided on the connecting shaft (10), and an annular sliding block matching with the annular sliding groove (30) is fixed on the inner wall of the connecting sleeve (32).

8. The corn seed breeding and sowing device according to claim 1, characterized in that: A cleaning plate (13) is fixed to the front end of the extension plate (5), the cleaning plate (13) is matched with the digging wheel (11), and the cleaning plate (13) is made of elastic material.

9. A corn seed breeding and sowing device according to claim 1, characterized in that: The hopper (15) and the hopper cover (16) are fixed by adsorption via a magnetic adsorption block, and a lifting groove (17) is provided at the top center of the hopper cover (16).

10. A method for using a corn seed breeding and sowing device, characterized in that: The corn seed breeding and sowing device according to claim 5 comprises the following steps: A digging wheel (11) of suitable size is selected according to the soil quality and the sowing depth. After the digging wheel (11) is selected, the connecting shaft (10) in the middle of the digging wheel (11) is connected to the rotating shaft (8) on both sides through a connecting mechanism, and then the corn seeds are placed in the hopper (15); The driving mechanism and the starting motor are started by the controller.
