Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a bio-fertilizer particle coating machine. Background Art

[0002] Biofertilizer is a product that contains both the nutrients needed by crops and microorganisms. It is a combination of biological, organic and inorganic substances. It can replace chemical fertilizers and provide various nutrients needed for the growth and development of crops. Most biofertilizers are made into slow-release fertilizers so that the biofertilizer can have a continuous effect on the land. To make biofertilizer into slow-release fertilizer, the fertilizer needs to be coated.

[0004] The device pours the bio-fertilizer particles into a feeding mechanism, which discharges the bio-fertilizer particles into a coating mechanism through the feeding mechanism, and at the same time discharges air into the coating mechanism through a circulation mechanism, so that the coating mechanism cooperates with the circulation mechanism to coat the bio-fertilizer particles. After the coating is completed, the bio-fertilizer particles are discharged through the coating mechanism, thereby improving the practicality of the equipment.

[0005] In the existing bio-fertilizer particle coating machine, the bio-fertilizer particles are not fully tumbled and stirred during the spraying of the coating liquid, and the bio-fertilizer particles are easily crushed. In addition, the excess coating liquid will accumulate at the bottom of the receiving structure and immerse the bio-fertilizer particles, affecting the subsequent operation of the bio-fertilizer particles.
