Technical Field

[0001] The utility model relates to the technical field of corn seed dressing devices, in particular to a corn seed dressing device. Background Art

[0002] Corn is one of the main food crops for humans worldwide. Its grains can be made into foods such as cornmeal, corn flour, and popcorn chips, and corn essential oil can be used in cooking and making finished oils. In addition, corn leaves and stems can be used as vegetables or feed foods. In addition to human consumption, corn is also an important feed crop. In order to improve the germination rate of corn and achieve the purpose of killing insects and sterilizing bacteria, corn seeds need to be mixed before sowing. However, existing seed mixing devices generally use metal stirring rods or blades to achieve the seed mixing and mixing operation of corn seeds, seed coating agents and fertilizers. However, during mixing, it is easy to damage the seeds and reduce the survival rate of the seeds. In addition, during mixing, there are dead corners that the metal stirring rods or blades cannot reach, and the uniformity of the mixing of corn seeds, seed coating agents and fertilizers cannot be guaranteed, and the quality of the seed mixing varies.
