Description
Technical Field
[0001] This utility model relates to the field of fertilizer production equipment technology, and in particular to a slow-release urea fertilizer coating device. Background Technology
[0002] Slow-release urea fertilizer controls the nutrient release rate through coating technology, which matches the nutrient requirements of plant growth, reduces nutrient loss and the number of fertilizations, and improves fertilizer utilization. The coating process is a core step, and the performance of the equipment directly affects the uniformity of fertilizer coating and production efficiency.
[0003] Existing coating devices often suffer from insufficient material mixing, making it difficult for the coating material to contact urea granules evenly. This results in uneven coating thickness, affecting the slow-release effect. Furthermore, some devices lack a reasonable material conveying structure, causing material to accumulate during the coating process, hindering orderly advancement and efficient discharge. In addition, insufficient sealing performance can lead to material leakage or impurity contamination, further reducing product quality. Therefore, a slow-release urea fertilizer coating device needs to be designed to address these issues. Utility Model Content

Track rings are fixedly fitted onto the left and right sides of the outer surface of the coating roller, respectively. A feed groove is formed on the left end face of the coating roller, and a discharge groove is formed on the right end face. A feed cover is detachably connected to the left end of the coating roller via a snap fastener, and the feed cover is sealed to the feed groove. A discharge cover is detachably connected to the right end of the coating roller via a snap fastener, and the discharge cover is sealed to the discharge groove. Multiple fan-shaped plates are axially distributed on the inner wall of the coating roller, and these multiple fan-shaped plates are fixedly connected to the inner wall of the coating roller.

[0026] Please see Figure 1-5 This utility model provides a technical solution:
[0027] A slow-release urea fertilizer coating device, such as Figure 1-5 As shown, the system includes a load-bearing base 1, with four support plates 5 fixedly connected to the upper surface of the load-bearing base 1. The four support plates 5 are arranged horizontally. A power supply box 3 is fixedly connected to the front of the upper surface of the load-bearing base 1. A support seat 4 is fixedly connected to the middle of the upper surface of the load-bearing base 1, and the support seat 4 is located directly behind the power supply box 3 and spaced apart from the power supply box 3. Track grooves 6 are opened on the top of the support plate 5 on the left and the support plate 5 on the right. The four support plates 5 are rotatably connected to a drive coating assembly 2, which is horizontally mounted above the load-bearing base 1.
[0028] Please see Figure 4 The driving coating assembly 2 includes a dual-axis motor 21, which is fixedly mounted on the upper surface of the support base 4. The two output shafts of the dual-axis motor 21 extend outward in the horizontal direction and are respectively fixedly connected to connecting rods 22. The two connecting rods 22 are coaxially arranged. A main gear 23 is fixedly sleeved on the outer surface of each connecting rod 22. A driven gear ring 24 is meshed on the upper part of the outer surface of each main gear 23. The inner ring walls of the two driven gear rings 24 are fixedly connected to a mixing coating component 25. The mixing coating component 25 rotates through the meshing of the driven gear ring 24 and the main gear 23. The other end of the connecting rod 22 away from the dual-axis motor 21 is movably connected to the inner plate wall of the two intermediate support plates 5 through a bearing. The power supply box 3 is electrically connected to the dual-axis motor 21 through internal wiring. A control switch is provided on the front of the power supply box 3.
[0029] Through the above scheme: the dual-axis motor 21, which is fixedly connected to the support base 4, is started and stopped by the control switch on the front of the power box 3 and the internal circuitry. The two output shafts of the dual-axis motor 21 drive the coaxially arranged connecting rod 22 to rotate. The end of the connecting rod 22 away from the dual-axis motor 21 is movably connected to the two middle support plates 5 through bearings to ensure transmission stability. At the same time, the main gear 23 on the connecting rod 22 meshes with the driven gear ring 24 to drive the mixing coating component 25, which is fixedly connected to the inner ring wall of the driven gear ring 24, to rotate. This achieves stable power transmission and efficient driving of the mixing coating component 25, providing reliable power support for the slow-release urea fertilizer coating and effectively improving the transmission efficiency and operational stability of the device.
[0030] Please see Figure 5 The mixing and coating component 25 includes a coating roller 251, which is horizontally positioned directly above the support base 1. Track rings 252 are fixedly fitted onto the left and right sides of the outer surface of the coating roller 251, respectively. A feed groove 256 is formed on the left end face of the coating roller 251, and a discharge groove 257 is formed on the right end face. A feed cover 253 is detachably connected to the left end of the coating roller 251 via a snap-fit, and the feed cover 253 is sealed to the feed groove 256. A discharge cover 255 is detachably connected to the right end of the coating roller 251 via a snap-fit, and the discharge cover 255 is sealed to the discharge groove 257. The inner wall of the coating roller 251 is axially... Multiple sector plates 254 are distributed in the direction of the coating roller 251. The sector plates 254 are fixedly connected to the inner wall of the coating roller 251. The track ring 252 has a circular structure. The outer diameter of the track ring 252 is adapted to the groove width of the track groove 6. The two track rings 252 are rotatably engaged with the track grooves 6 of the left support plate 5 and the right support plate 5, respectively. The coating roller 251 is inclined inside. The axis of the coating roller 251 forms a 10° angle with the horizontal direction. The feed groove 256 side of the coating roller 251 is higher than the discharge groove 257 side. The inclination direction of the coating roller 251 is adapted to the spiral direction of the sector plates 254. The spiral helix angle of the sector plates 254 is in the same direction as the inclination angle of the coating roller 251.
[0031] Through the above scheme: the coating roller 251 of the mixing coating component 25 is rotatably engaged with the track rings 252 fixedly sleeved at both ends and the track grooves 6 on the top of the left and right support plates 5. The outer diameter of the track rings 252 is adapted to the groove width of the track grooves 6, ensuring the stability of the coating roller 251 during rotation. The coating roller 251 is inclined at 10°, with one side of the feed trough 256 higher than the other side of the discharge trough 257, and its inclination direction is adapted to the spiral direction of the multiple fan-shaped plates 254 distributed axially inside, with the spiral helix angle in the same direction. It is engaged with the feed cover 253, which is detachably connected to the left end by a snap and is sealed to the feed trough 256, and the feed cover 253, which is detachably connected to the right end by a snap and is sealed to the discharge trough 257. The combined discharge cover 255 allows for easy opening of the feed cover 253 to add urea fertilizer and coating material through the feed trough 256. After closing the feed cover 253, the fan-shaped plate 254 can fully agitate and mix the material during the rotation of the coating roller 251. Furthermore, the spiral structure and the tilt angle of the coating roller 251 work together to slowly move the material towards the discharge trough 257, achieving uniform coating and orderly discharge. The sealed feed cover 253 and discharge cover 255 also prevent material leakage and the entry of external impurities, effectively improving coating uniformity, ease of operation, and material cleanliness, thus ensuring the coating quality and production efficiency of the slow-release urea fertilizer.
[0032] It should be noted that this utility model is a slow-release urea fertilizer coating device. When the slow-release urea fertilizer coating device is working, the dual-axis motor 21 electrically connected to the power supply box 3 is started by the control switch on the front of the power supply box 3. The two output shafts of the dual-axis motor 21 drive the coaxially arranged connecting rod 22 to rotate. The end of the connecting rod 22 away from the dual-axis motor 21 is movably connected to the two middle support plates 5 through bearings. At the same time, the main gear 23 on the connecting rod 22 rotates synchronously. The main gear 23 meshes with the driven gear ring 24, causing the mixing coating component 25, which is fixedly connected to the inner ring wall of the driven gear ring 24, to rotate accordingly. The coating roller 251 of the mixing coating component 25 rotates with the track grooves 6 on the top of the left and right support plates 5 through the track rings 252 at both ends to ensure rotational stability. First, open the feed that is detachably connected by the buckle. Urea fertilizer and coating material are added to the coating roller 251, which is inclined at 10° to the side of the feeding trough 256 and is higher than the side of the discharge trough 257, through the cover 253. After the feeding cover 253 is closed, during the rotation of the coating roller 251, multiple fan-shaped plates 254 with the same spiral angle as the inclination direction of the coating roller 251 thoroughly mix and stir the urea fertilizer and coating material. In the rotating coating roller 251, with the help of the tilt angle and the turning and pushing action of the spirally arranged fan-shaped plates 254, the material is fully mixed and uniformly coated. Then, it gradually moves to the lower discharge trough 257, and finally the dual-shaft motor 21 stops. The discharge cover 255, which is detachably connected by a buckle, is opened, and the coated slow-release urea fertilizer is discharged through the discharge trough 257, completing the coating process of the slow-release urea fertilizer.
