A kind of seed coating machine and seed coating method

Abstract

The invention provides a seed coating machine which comprises a feeding device, an atomizing chamber, a stirring box, a reagent supply device and a rack, wherein the atomizing chamber is connected with the feeding device in a matching manner; the stirring box is connected with the atomizing chamber in a matching manner; the reagent supply device is used for supplying reagent liquids into the atomizing chamber; the reagent supply device comprises a seed coating agent box and a first reagent supply tube which is communicated with the seed coating agent box and the atomizing chamber; an electrostatic device is arranged on the first reagent supply tube. By adopting the seed coating machine, the atomization degree is further increased under the condition that the overall structure of the seed coating machine is not changed, concave parts of umbilical regions of seeds can be covered, and the purpose of increasing the pass percent of seed coating is achieved; the seed coating machine is also applicable to atomization on the seeds under the condition that the seeds are mingled with dust in the atomizing chamber, and the pass percent of seed coating is also increased.

Description

technical field [0001] The present invention relates to seed coating in the field of agriculture, and more specifically, relates to a seed coating machine and a seed coating method. Background technique [0002] Seed coating is the use of adhesives or film-forming agents to wrap pesticides, fertilizers, insecticides, fungicides and other active ingredients on the surface of seeds, which can improve the ability of seeds to resist pests and diseases, enhance the stress resistance of seedlings, and promote the healthy and rapid growth of seedlings , is a key technology to increase crop yield, save seeds and pesticide consumption, and reduce environmental pollution, and has been widely used in modern agriculture. [0003] Seed coating methods are divided into two types: pelletization and film coating; pellet coating is suitable for seed types with irregular shapes or small volumes, which is conducive to mechanized precision sowing, and the coating pass rate is high. However, th...

AI Technical Summary

Problems solved by technology

[0008] It can be seen from the above process that none of the existing seed coating machines adopts the principle of electrostatic atomization to improve the coating process, making it difficult to further improve the degree of atomization, and the sunken parts such as the navel of the seed can be covered. Clothing qualified rate and effect are difficult to further improve
