AI Technical Summary

Technical Problem

Existing corn seed coating devices lack a drying structure, resulting in a moist coating agent on the seed surface. This can easily lead to seeds sticking together and the coating agent falling off, increasing the difficulty of sowing.

Method used

A drying structure with a blower and heating wire is designed, combined with a spiral blade stirring assembly, to achieve rapid drying and uniform adhesion of the seed coating agent. The heating fan heats the air into hot air, which enters the coating chamber through a grid plate and comes into contact with the seeds during stirring to evaporate moisture. Combined with the stirring action of the spiral blades, the coating agent is ensured to solidify and adhere.

Benefits of technology

It effectively prevents seeds from sticking together, ensures stable adhesion of the coating agent, improves the coating effect, reduces sowing difficulties, and improves seed quality.

Abstract

The utility model provides a kind of for corn planting seed coating device, including frame body and install coating bin on frame body, the frame body is provided with stirring assembly, the stirring assembly includes driving motor and connecting shaft, spiral blade is fixedly installed on the connecting shaft, the driving motor is used to drive connecting shaft rotation.The utility model is communicated with extension ring on the upper end of cover plate, and integrates the drying structure of "blower fan+heating wire":blower fan inhales outside air downward into extension ring, heating wire heats air into hot air of suitable temperature, and hot air enters coating bin through grid plate, and seed in stirring is contacted fully, and water in coating agent is evaporated in real time, and coating agent is solidified rapidly and adhered on seed surface;Meanwhile, the air pipe on cover plate can discharge humidity and excess hot air in bin in time, maintain dry environment in bin, fundamentally avoid the problem of seed adhesion, reduce coating agent drop, guarantee coating stability.
