Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer coating technology, specifically to a coating device for high-tower compound fertilizer processing. Background Technology

[0002] Compound fertilizers are chemical fertilizers containing two or more nutrients. They have advantages such as high nutrient content, few by-products and good physical properties. They play a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable crop yields. However, in the production and processing of compound fertilizers, they need to be coated, so appropriate coating devices are required.

[0003] For example, Chinese patent application No. 202420759102.0 discloses a coating device for compound fertilizer production, including a box body. Two conveyor belts are rotatably connected to the inner wall of the box body. The two conveyor belts are arranged vertically and at an angle. A material frame is fixedly connected to the top surface of the outer wall of the box body near one end of the conveyor belts. The material frame is connected to the box body. Strip nozzles are fixedly connected to the inner wall of the box body near the middle of the two conveyor belts. The film liquid is sprayed onto the conveyor belts by a pump and the strip nozzles. Compound fertilizer is placed inside the material box. The speed at which the compound fertilizer enters the box body is controlled by a sliding baffle. The two conveyor belts are arranged at an angle and rotate upwards. The compound fertilizer moves downwards due to gravity. The rotating conveyor belts can make the compound fertilizer rotate, which can break it up. When the rotation passes through the strip nozzles, the film liquid can be more evenly applied to the surface of the compound fertilizer. Finally, the compound fertilizer is discharged from the outlet.

[0004] However, the following problem still exists in this technical solution: the side of the compound fertilizer that comes into contact with the conveyor belt cannot be coated, thus affecting the coating efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a coating device for high-tower compound fertilizer processing. The device uses a mixing mechanism and a spraying mechanism to ensure thorough mixing between the compound fertilizer and the film liquid, thereby improving coating efficiency. The device also uses a feeding mechanism to facilitate the feeding of the coated compound fertilizer, making it easier for workers to collect it, thus addressing the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating device for processing high-tower compound fertilizer, comprising a mixing cylinder, a spraying mechanism for adding thin film liquid into the mixing cylinder, a feed trough connected to one end of the mixing cylinder, and a mixing mechanism for stirring the compound fertilizer inside the mixing cylinder.

One end of the second rotating shaft passes through the mixing cylinder and extends out of one side of the mixing cylinder. The second rotating shaft is movably connected to the mixing cylinder via a bearing. A second motor is fixedly mounted on one end of the second rotating shaft for stirring the compound fertilizer.

[0010] Preferably, the bottom of the mixing drum is provided with a feeding mechanism to facilitate the feeding of compound fertilizer. The feeding mechanism includes a mounting plate at the bottom of the mixing drum, with sealing plates inserted on both sides of the mounting plate. A limiting plate is provided at the bottom of the sealing plate, and mounting brackets are provided on both sides of the bottom of the mounting plate. One mounting bracket has a bidirectional threaded rod movably connected inside through a bearing. The bidirectional threaded rod passes through the limiting plate and is threadedly connected to the limiting plate. A third motor is fixedly installed at one end of the bidirectional threaded rod. The other mounting bracket has a sliding rod inside, which passes through the limiting plate to facilitate the feeding of compound fertilizer.

[0011] Preferably, the bottom of the mixing drum is provided with a support mechanism for supporting the mixing drum.

The rotation of the second rotating shaft can drive the stirring plate to rotate. The stirring plate can stir the compound fertilizer, so that it can be fully mixed with the film liquid, thereby improving the coating efficiency. 2. Start the third motor. The third motor can drive the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives the limit plate to move. The movement of the limit plate can drive the sealing plate to move. Remove the sealing plate from the bottom of the mixing drum, and the compound fertilizer inside the mixing drum will flow into the collection box for easy discharge. Attached Figure Description
