Description

Technical Field

[0001] This utility model relates to the field of coating device technology, specifically a compound fertilizer coating device based on a bioactive carrier. Background Technology

[0002] Compound fertilizers are chemical fertilizers containing two or more nutrients. They are characterized by high nutrient content and good physical properties, but the nutrient ratios are fixed. Therefore, their application requires soil testing and formulation with single-element fertilizers to improve effectiveness. Based on nitrogen and potassium sources, they can be classified into nitrate-sulfur-based, sulfur-based, chlorine-based, and urea-based types. Nitrate-sulfur-based fertilizers are fast-acting and suitable for dryland fields, sulfur-based fertilizers can improve sulfur-deficient soils, and chlorine-based fertilizers should be avoided for chlorine-sensitive crops. To slow down the release rate of compound fertilizer, it is necessary to coat it after production, which is called coated fertilizer. Coated fertilizer is a slow-release fertilizer formed by physical coating technology. Its core principle is to use inorganic or organic materials to form a semi-permeable membrane layer, and achieve synchronization with the crop's fertilizer requirements through diffusion or rupture mechanisms. The main coating materials include sulfur, high molecular polymers, resins and mineral-organic composite materials. Different materials are optimized for slow-release performance through thickness control, osmotic pressure regulation and composite modification. After the fertilizer is coated, it needs to be dried to prevent the compound fertilizer from clumping together. In addition, traditional fertilizer output points are mostly single-point output, which has low output efficiency. In order to better produce compound fertilizer through coating, a compound fertilizer coating device based on a bioactive carrier is proposed.

[0003] For example, the coating device for compound fertilizer production disclosed in the authorization announcement number CN222250531U includes a base plate, and a drive assembly for driving the coating roller to rotate is fixedly installed on the top of the base plate. The surface of the coating roller is provided with two sets of annular grooves, and the inner cavity of the two sets of annular grooves is rolledly connected with a limiting assembly for preventing the coating roller from detaching. The limiting assembly is installed on the top of the base plate. Although it achieves the goal of limiting the coating roller by setting the limiting component, thereby preventing the material from being on one end of the coating roller and causing uneven loading on both sides, which could easily lead to the coating roller falling off, thus improving the stability of the device; the setting of a second roller rotatably connected to the U-shaped clamp, with the second roller rolling and connected to the inner cavity of the annular groove, thereby avoiding the surface of the U-shaped clamp from contacting the coating roller and causing excessive friction; the setting of the U-shaped plate and the jack, controlling the extension and retraction of the jack's telescopic end, and lifting the coating roller through the U-shaped plate, thus facilitating the replacement of the second roller by the operator; However, this does not solve the problem that existing coating devices are not conducive to uniformly spraying coating liquid onto compound fertilizer granules during use, nor to flexibly adjusting the output position of compound fertilizer granules, thus affecting the flexibility of compound fertilizer output. Utility Model Content

[0004] The purpose of this invention is to provide a compound fertilizer coating device based on a bioactive carrier, in order to solve the problems mentioned in the background art, such as the difficulty in uniformly spraying coating liquid onto compound fertilizer particles, the inability to flexibly adjust the output position of compound fertilizer particles, and the impact on the flexibility of compound fertilizer output.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compound fertilizer coating device based on a bioactive carrier, comprising a support frame and a drying box. The drying box is disposed on the side wall of the support frame. Multiple sets of heating wires at equal intervals are disposed in the interlayer inside the drying box. Second servo motors are symmetrically disposed on the side wall of the drying box, and stirring racks are installed at the output ends of the second servo motors.

[0010] Preferably, a coating barrel is movably disposed at the top of the adjustment plate, and a first toothed ring is disposed on the outer surface of the coating barrel.

[0011] Preferably, a first servo motor is provided at the top of the adjustment plate on one side of the first gear ring, and a first gear is installed at the output end of the first servo motor, and the first gear meshes with the first gear ring.

[0012] Preferably, a liquid storage tank is symmetrically arranged at the top of the adjustment plate on one side of the coating barrel, and a water pump is provided at the top of each liquid storage tank. The output end of each water pump is equipped with a water outlet pipe, which extends into the interior of the coating barrel.

[0013] Preferably, the inner wall of the coating barrel is provided with multiple sets of guide strips at equal intervals, and the guide strips are fixedly connected to the coating barrel.

[0014] Preferably, a PLC controller is provided on the outer wall of the support frame on one side of the electric push rod, and the output terminal of the PLC controller is electrically connected to the input terminals of the electric push rod, water pump, first servo motor, fourth servo motor, electric valve, second servo motor, heating wire, and third servo motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the coating device not only realizes the uniform spraying of coating liquid onto compound fertilizer granules, facilitating flexible adjustment of the output position of compound fertilizer granules, but also improves the flexibility of compound fertilizer output.

[0016] (1) The compound fertilizer granules are introduced into the coating tank. The first servo motor drives the first gear to rotate, and the first gear drives the coating tank to rotate through the first gear ring. The coating tank drives the compound fertilizer granules to rotate. At the same time as the coating tank rotates, the water pump pumps the coating liquid in the storage tank into the outlet pipe and sprays it onto the surface of the compound fertilizer through the outlet pipe. Under the action of the rotation of the coating tank, the coating liquid is evenly contacted with the compound fertilizer granules to complete the coating. The coating liquid contains a bioactive carrier. At the same time, under the guiding action of the coating tank, the coated compound fertilizer is transported to the inside of the drying box. Heat is transferred into the drying box by the heating wire and The compound fertilizer is heated, and a second servo motor drives a stirring frame to rotate, which stirs the compound fertilizer to ensure even heating and better drying. Then, an electric valve is opened, and the dried compound fertilizer granules pass through the electric valve, output pipe, and connecting pipe into the discharge pipe. A fourth servo motor drives a spiral blade to rotate, which moves the compound fertilizer granules and outputs them from the discharge pipe, completing the coating process. This design allows for uniform spraying of coating liquid onto the compound fertilizer granules, preventing them from clumping together and facilitating the output of the coated compound fertilizer.

[0017] (2) The push arm is moved by the electric push rod, and the push arm drives the adjustment plate to rotate around the connecting shaft through the hinge shaft. The adjustment plate drives the coating barrel to rotate, thereby adjusting the angle between the coating barrel and the support frame. Under the action of gravity, the speed of compound fertilizer moving in the coating barrel is accelerated. When it is necessary to adjust the material output position, the second gear is driven by the third servo motor to rotate. The second gear drives the connecting pipe to rotate through the second gear ring. The connecting pipe drives the discharge pipe to rotate, thereby adjusting the discharge position of the discharge pipe. This allows the compound fertilizer to be output from different positions, which can improve the flexibility of material output. Attached Figure Description
