[0002] The spoon-type potato seeders are widely used at home and abroad at present, and have the characteristics of simple structure, high reliability and strong adaptability, but have the problem of high missing seeding. In the actual operation process, the missing seeding spoons are generally reseeded manually to prevent missing seeding and holes. However, the manual reseeding has the problems of high working strength, poor operation quality, high production cost and low efficiency, and cannot meet the precision of reseeding under high-speed operation. At present, an effective method for solving the problem of missing seeding of the potato seeder is to detect the missing seeding and automatically reseed through a reseeding device. The moving speed of the potato seeder is mostly 3-4 km / h at present, the moving speed is slow, the seeding time is long, the existing missing seeding device of the seeder can only reseed once for the low-speed seeding, and the existing missing seeding device of the seeder cannot meet the speed requirement, cannot realize continuous reseeding, and has poor reseeding effect for the high-speed seeder with a moving speed higher than 5 km / h. In addition, according to the application practice, it is found that the existing missing seeding detection device of the potato seeder using the laser sensor has high requirements for the size of the potato, has low detection accuracy, and the existing automatic reseeding device has low reseeding success rate when reseeding at high speed, and cannot reseed in time when continuous missing seeding occurs, especially for the cut seed potatoes, the reseeding process will cause blockage.

[0054] If two first seed spoons 25 are short of seed:

[0055] T23. The second electromagnetic valve 55 pushes the newly moved seed potato in the second groove 54 into the first seed cover 27, and then the second electromagnetic valve 55 resets; due to the fast speed of the electromagnetic valve, the speed of the conveying chain can be made up, so that the continuous two-time seed supplement can be completed during the high-speed movement of the seeding machine;

[0056] T24. The second motor 32 drives the seed spoon 34 to rotate, so that the seed potato falls into the first groove 51;

[0060] The seed falling camera 12 takes pictures and records according to the seed dropping frequency, identifies whether there is a seed potato under the first seed cover 27, and sends a no seed potato signal if no seed potato is found. The picture recognition result of the seed falling camera 12 at the same sowing position is compared with the picture recognition result of the first seed scoop camera 26. If neither the no seed potato signal nor the missing seed signal exists, it proves that the main seed dropping device is normally sowing. If both the no seed potato signal and the missing seed signal exist, the reseeding is unsuccessful. If only the missing seed signal exists, the reseeding is successful. According to the comparison of the picture recognition result of the seed falling camera 12 and the picture recognition result of the first seed scoop camera 26, the normal sowing rate of the main seed dropping device and the reseeding success rate of the reseeding device are obtained. The reseeding success rate can also be achieved by manual checking. After the reseeding is completed, the operator manually checks the pictures saved by the seed falling camera 12 and the first seed scoop camera 26.

The first electromagnetic valve (52) pushes the seed potatoes in the first seed groove (51) into the second seed groove (54) for seed waiting, and then the first electromagnetic valve (52) resets, and at the same time, the second motor (32) drives the reseeding scoop (34) to rotate, so that the seed potatoes fall into the first seed groove (51) for seed waiting; If two first scoops (25) are missing in succession: T23. The second electromagnetic valve (55) pushes the newly moved seed potatoes in the second seed groove (54) into the first seed cover (27), and then the second electromagnetic valve (55) resets; T24. The second motor (32) drives the reseeding scoop (34) to rotate, so that the seed potatoes fall into the first seed groove (51); T25. The first electromagnetic valve (52) pushes the seed potato in the first groove (51) into the second groove (54) for sowing, and then the first electromagnetic valve (52) resets, while the second motor (32) drives the seed spoon (34) to rotate, so that the seed potato falls into the first groove (51) for sowing.

4. The method of claim 1, wherein the method is characterized by, A first brush (53) is arranged between the first groove (51) and the second groove (54), and a second brush (56) is arranged between the second groove (54) and the seed supplementing opening (28), and the lower edge of the first brush (53) and the second brush (56) is lower than the upper edge of the seed potato.

5. The method of claim 1, wherein the method is characterized by, A rubber buffer layer is arranged inside the second groove (54).

6. The method of claim 1, wherein the method is characterized by, The seed falling camera (12) takes pictures and records according to the seed dropping frequency, identifies whether there is a seed potato falling below the first seed cover (27), and sends a no seed signal if no seed potato is found.
