Technical Field
The invention relates to the field of seeder compensation devices, in particular to a rebroadcast miss-seeding compensation device for a seeder.
Background
When the seeder performs a seeding operation, the seeder generally travels at a constant speed on the field, and the seeds are dropped onto the field one by one at the same time interval, so that the seeds can be uniformly sown in sequence on the field at the same distance interval. However, in practical use, the problems of re-sowing and miss-sowing are easy to occur due to both the seeds and the sowing machine. The rebroadcasting is that two or even a plurality of seeds are adhered to each other, so that a plurality of seeds are gathered into the same particulate matters and fall into the field from the seeder, and rebroadcasting is performed on the same position of the field; the missing seeding is usually caused by overlong falling time interval between two seeds by the seeder, so that the travelling distance of the seeder is overlarge before the next seed falls, the distance interval between the falling positions of the two seeds is increased, and a missing seeding position appears between the two seeds. The existing seeder lacks the capability of avoiding rebroadcasting and miss-seeding, and is easy to cause miss-seeding and rebroadcasting conditions under the complex operation environment of field seeding so as to influence crop yield and agricultural production cost.
