Description

Technical Field

[0001] The utility model belongs to the technical field of seed coating, and in particular relates to a seed coating and heating machine. Background Art

[0002] Seed coating refers to the use of adhesives or film-forming agents, using a specific seed coating machine, to wrap non-seed materials such as fungicides, pesticides, micro-fertilizers, plant growth regulators, colorants or fillers around the outside of seeds, so as to make the seeds spherical or basically maintain their original shape, improve their stress and disease resistance, accelerate germination, promote seedling formation, and increase yield.

[0003] The seeds need to be heated before coating to avoid the waxing phenomenon caused by too low temperature, which makes the seed coating agent unable to form a film. Existing seed heating equipment mostly heats the seeds by introducing heated gas. However, since the heated gas enters the bin from a single air inlet and the seeds are piled up in the bin, the temperature of some seeds close to the air inlet is too high, and the temperature of some seeds far from the air inlet is not obvious, which makes the seed heating very uneven, greatly affecting the film-forming effect of subsequent seed coating. Utility Model Content

[0004] The utility model aims to provide a seed coating and heating machine to solve the problem of uneven seed heating in existing seed heating equipment.

[0005] The technical solution adopted by the utility model is as follows:
