Description
Technical Field
The invention relates to the field of agricultural machinery, in particular to an automatic miss-seeding detection and reseeding device of a corn planter.
Background
China is a large agricultural country, and agricultural mechanization industry of China has been developed to a medium stage. The traditional manual sowing is replaced by a large amount of mechanization, and at the beginning, the agricultural operation is performed by a ditching type sowing machine, but due to the waste of seeds and high cost, the seedling removal and seedling supplement are performed at the later stage to change the spacing between seedlings, so that the waste of manpower and material resources is caused. Because of these disadvantages, the current seeder has replaced the ditching seeder by the hole-nest type seeder, thereby ensuring the plant spacing, saving manpower and material resources, but the phenomenon of blocking and missing seeding is unavoidable in both ditching and hole-nest type, and the precision seeding technology is continuously developed, and becomes the main characteristic of the modern seeding technology.
For large grain crops, precision seeding is a direction of future development. The precision seeding device has the advantages of seed saving, high yield, economy and the like, but the seeding missing phenomenon is unavoidable in the seeding operation due to the restriction of the design and the use condition of a seed discharging system. The existing precision seeder for various large-grain crops has the average miss-seeding rate of about 11.74%, and the marginal effect around each 250g miss-seeding hole is calculated by 2% according to 500 plants/667 m < 2 >, so that the miss-seeding loss of the corn is as high as 117.4Kg/hm < 2 >. If the seeds are manually reseeded or transplanted at the miss-seeding position after the seedlings emerge, the seeds cannot grow normally due to the growth difference, and the high-quality automatic reseeding of the miss-seeding device is needed during the seeding.
Most of the existing reseeding devices adopt a mechanical seed sowing mode, and a plurality of hard structural members are required to be used, so that seeds are easily damaged and nutrients on the surfaces of the seeds are manually added in the reseeding process, and the germination rate of the seeds is affected. The existing miss-seeding detection and reseeding devices are mostly integrated together, namely, the reseeding is performed by the seeder immediately when miss-seeding occurs, and the problems of miss-seeding, multicast and the like still easily occur under the condition that the seeder fails. And because the seeder is continuously advancing, a certain distance exists between the reseeding position and the position of missing sowing in the reseeding mode, so that the reseeding precision is reduced.
