Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer production technology, specifically to a controlled-release fertilizer coating device. Background Technology
[0002] Compound fertilizer is a chemical fertilizer containing any two or three of the crop nutrients nitrogen, phosphorus, and potassium, produced by chemical or mixing methods. Its function is to meet the comprehensive and balanced needs of agriculture under different production conditions for various nutrients. During its production, dry powder materials are mixed and granulated into finished compound fertilizer products. After the finished compound fertilizer products are granulated, they often need to be coated to make the compound fertilizer more effective in subsequent use. Pesticide-fertilizer is a new type of ecological compound fertilizer formed by mixing pesticides and fertilizers in a certain proportion and stabilizing the fertilizers and pesticides in a specific compound system through certain processes. Generally, fertilizers are used as carriers for pesticides.
[0003] In existing controlled-release fertilizer coating devices, materials tend to adhere to the inner wall of the equipment and accumulate during recycling, making cleaning difficult and reducing the quality of fertilizer recycling and coating. In addition, the equipment requires manual labor to place the fertilizer and coating agent into the mixing tank for mixing and stirring during the coating operation. This results in multiple feedings and coatings, which increase the workload of the personnel. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a controlled-release fertilizer coating device, which has the advantages of clean coating equipment and improved fertilizer coating efficiency, thus solving the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a controlled-release fertilizer coating device, comprising a support plate, a controller fixedly installed on the outer wall of the support plate, a feeding cylinder fixedly installed on the top of the support plate, a first motor fixedly connected to the top of the feeding cylinder, a spiral feeding rod fixedly mounted on the power output shaft of the first motor, a through pipe fixedly connected to the outer wall of the feeding cylinder, a mixing tank fixedly connected to the through pipe, a third motor fixedly connected to the top of the mixing tank, a stirring rod fixedly mounted on the power output shaft of the third motor, a second motor fixedly installed on the top of the mixing tank, a gear fixedly mounted on the power output shaft of the second motor, a toothed plate meshing with the outer wall of the gear, a scraper fixedly connected to the toothed plate, a water tank fixedly installed on the top of the support plate, a water pump fixedly installed in the water tank, a water pipe fixedly connected to the water pump, a nozzle fixedly installed on the water pipe, a bracket fixedly installed at the bottom of the support plate, and a discharge pipe fixedly installed at the bottom of the mixing tank.
[0006] As a preferred technical solution of this utility model: the controller is electrically connected to the first motor, the feed inlet is fixedly installed on the outer wall of the feed cylinder, and the spiral feed rod is in contact with the inner wall of the feed cylinder.
[0007] As a preferred technical solution of this utility model: the controller is electrically connected to the third motor, and the stirring rod is located at the center of the inner wall of the mixing tank.
[0008] As a preferred technical solution of this utility model: the controller and the second motor are electrically connected, and the gear meshes with the outer wall of the rotating groove.
[0009] As a preferred technical solution of this utility model: the number of scrapers is four, and the four scrapers are evenly distributed on the outer wall of the toothed plate.
[0010] As a preferred technical solution of this utility model: the controller and the water pump are electrically connected, and the water pipe is connected to the nozzle through the top of the mixing tank.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This controlled-release fertilizer coating device uses a second motor driven by a controller to rotate a gear on the inner wall of a rotating groove. The gear meshes with the outer wall of the rotating groove, causing the rotating groove to drive a scraper to scrape and clean the residue on the inner wall of the mixing box. This prevents material from adhering to the inner wall of the mixing box, which would reduce production quality due to the equipment's continuous coating process. The controller also uses a water pump to draw water from the inner wall of the water tank to the inner wall of the water pipe, and then uses the water pipe to deliver the water to the nozzle, which sprays water to thoroughly clean the inner wall of the mixing box.
[0012] 2. This controlled-release fertilizer coating device places the fertilizer and coating agent to be coated on the inner wall of the inlet. An external force-controlled controller is used to drive the screw conveyor rod to rotate, so that the fertilizer is pushed forward along the rotation path by the screw conveyor rod. The agent on the inner wall of the conveying cylinder is transported to the inner wall of the inlet and outlet through the pipe, thereby replacing manual feeding and improving production efficiency.

[0022] In a preferred embodiment: the controller 2 is electrically connected to the second motor 7, and the gear 8 meshes with the outer wall of the rotating groove 18.
[0023] In the above structure, the control controller 2 uses the second motor 7 to drive the gear 8 to rotate on the inner wall of the rotating groove 18.
