Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, and particularly relates to a fertilizer granulation coating device. Background Technique

[0002] Coated fertilizers, also known as coated fertilizers, refer to a type of fertilizer in which the surface of water-soluble fertilizer particles is coated with a semi-permeable or poorly soluble film, having the characteristic of slow nutrient release. The outer surface of coated fertilizers is usually wrapped with a biodegradable coating. Water penetrates through this coating into the interior of the fertilizer, uniformly dissolving the nutrients in the particles. The dissolved nutrient elements then penetrate out of the coating with changes in the external environment. The nutrients are evenly distributed, and the fertilizer effect is stable and long-lasting, which can promote high yields of crops.

[0003] The Chinese patent authorization announcement number is CN217077454U, and the name is a fertilizer coating device, including a bottom plate. A support plate is fixedly connected to the bottom plate. A motor is fixedly connected to the support plate. The output end of the motor is rotationally connected to the support plate. The output end of the motor is fixedly connected to a rotating cylinder. The rotating cylinder contacts the support plate. A scraping blade is in contact with the inner wall of the rotating cylinder. A stirring rod is fixedly connected to the scraping blade. A fixed pipe is fixedly connected to the stirring rod. Through holes are formed in the fixed pipe. By designing the function of the motor, the motor can drive the rotating cylinder to rotate, enabling the rotating cylinder to rotate relative to the fixed pipe and the stirring rod, which can play a role in stirring the materials inside the rotating cylinder. At the same time, the liquid inlet pipe can input the film liquid into the fixed pipe, making the mixing of fertilizer particles and the film liquid more uniform. At the same time, the relative rotation of the scraping blade and the rotating cylinder can scrape off the film liquid attached to the inner wall of the rotating cylinder, improving the fertilizer coating effect.

[0004] The deficiencies of the above-mentioned prior art solutions are as follows: Although the above solution inputs the film liquid through the fixed pipe, making the mixing of fertilizer particles and the film liquid more uniform, and at the same time, the relative rotation of the scraping blade and the rotating cylinder can scrape off the film liquid attached to the inner wall of the rotating cylinder, improving the fertilizer coating effect, when feeding, granular fertilizers are prone to accumulate at the feeding port, resulting in only a small amount of fertilizer being coated in one operation, reducing the production efficiency and causing many inconveniences to the production work.
