Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production, and in particular to a cooling device for the production of high slow-release compound fertilizer. Background Technology

[0002] High-slow-release compound fertilizers control the release rate of nutrients by adding slow-release agents, allowing the fertilizer's nutrients to be gradually released and supplied to crops. This greatly reduces the frequency of fertilization and improves nutrient utilization. Unlike traditional fertilizers that require frequent application, high-slow-release compound fertilizers only need to be applied once at the beginning of the crop's growth period to meet the nutrient requirements for crop growth and development. This not only simplifies the operation for farmers but also reduces the environmental pollution caused by fertilization.

[0003] After the production of high-slow-release compound fertilizer, the fertilizer needs to be cooled. However, the common cooling method is to place the fertilizer on a flat surface and cool it by blowing cold air or releasing cold air. The existing cooling devices for high-slow-release compound fertilizer production have low cooling efficiency, and the accumulation of fertilizer and the one-sided cooling method can easily cause uneven cooling and affect the cooling effect.

[0004] Therefore, in view of the problems of low cooling efficiency and uneven cooling effect caused by the single-sided cooling method of the existing cooling devices for the production of high slow-release compound fertilizers, a cooling device for the production of high slow-release compound fertilizers can be designed to facilitate the transportation of fertilizers, increase the cooling treatment time of high slow-release compound fertilizers, and improve the cooling efficiency. Utility Model Content

[0005] In order to overcome the problems of low cooling efficiency and uneven cooling caused by the single-sided cooling method of existing cooling devices for the production of high slow-release compound fertilizers, which affect the cooling effect.

[0006] The technical solution of this utility model is as follows: a cooling device for the production of high slow-release compound fertilizer, including an outer casing and a conveyor belt. A feeding hopper is provided on the upper side of the outer casing, and the lower end of the feeding hopper is connected to the top of the outer casing. A feeding assembly is provided at the bottom of the inner side of the feeding hopper. A support foot is provided at the bottom of the outer casing. Five conveyor belts are provided and are distributed in a staggered manner. A drive motor is provided on the front end of the outer casing. A cooling fan is fixedly installed on the top of the outer casing on the side of the feeding hopper. A ventilation box is fixedly installed at the rear end of the outer casing. An air supply plate is provided on the inner side of the outer casing above the conveyor belt. A discharge port is opened at the bottom of the right end of the outer casing.

[0007] Preferably, the high slow-release compound fertilizer is fed into the outer casing through the feed hopper, and the feeding amount is controlled by the feeding component, so that the fertilizer is evenly spread on the conveyor belt. The conveying of multiple conveyor belts increases the cooling time of the fertilizer, and the transfer of fertilizer falling on multiple conveyor belts makes it easy to turn the fertilizer, ensuring the uniformity of cooling and improving the cooling efficiency.

[0008] As a preferred option, the front end of the outer casing is provided with ventilation slots, which are adapted to the conveyor belt.

[0009] Preferably, the feeding assembly includes a rotating shaft with blades fixedly mounted on its surface. The blades are arranged in a circular array. The front and rear ends of the rotating shaft are rotatably connected to the two ends of the feeding hopper, respectively. A servo motor is provided at the front end of the feeding hopper, and the output end of the servo motor is fixedly connected to the front end of the rotating shaft.

[0010] Preferably, drive rollers are provided at both ends of the inner side of the conveyor belt. The front end of the drive roller is fixedly connected to the output end of the drive motor, and the two ends of the drive roller are rotatably connected to the inner wall of the outer casing.

[0011] Preferably, a guide block is fixedly installed on the surface of the inner wall of the outer box. The guide block has a triangular structure design, and the bottom of the guide block is in close contact with the conveyor belt. The guide block and the conveyor belt correspond one-to-one.

[0012] Preferably, the output end of the cooling fan is connected to the top of the ventilation box via a pipe, the rear end of the air supply plate is connected to the ventilation box, and an air outlet slot is provided on the lower end face of the air supply plate.

[0013] Preferably, the bottom of the outer casing is provided with a discharge guide plate, one end of which is adapted to the bottom of the conveyor belt, and the other end of which is adapted to the discharge port.

[0014] The beneficial effects of this utility model are:

[0015] 1. This cooling device for producing high-slow-release compound fertilizer uses conveyor belts to transport the high-slow-release compound fertilizer, allowing the fertilizer to move within the outer casing. Cooling fans blow air while the fertilizer is being transported, and the combination of multiple conveyor belts allows the fertilizer to move back and forth, increasing the cooling time. When the fertilizer falls onto the lower conveyor belt, it is turned over, ensuring uniform cooling and improving the cooling effect.

[0016] 2. This cooling device for producing high-slow-release compound fertilizer allows the high-slow-release compound fertilizer to be fed into the outer casing through the feed hopper and fall onto the conveyor belt for easy cooling. The servo motor drives the rotation of the rotating shaft and the blades to control the amount of fertilizer fed, preventing excessive accumulation of fertilizer on the conveyor belt and ensuring that the fertilizer is evenly spread on the conveyor belt, thus guaranteeing cooling efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-4 This utility model provides an embodiment of a cooling device for the production of high-slow-release compound fertilizer, including an outer casing 1 and a conveyor belt 4. A ventilation slot 101 is provided on the front end face of the outer casing 1, and the ventilation slot 101 and the conveyor belt 4 are adapted to each other. A feeding hopper 2 is provided on the upper side of the outer casing 1, and the lower end of the feeding hopper 2 is connected to the top of the outer casing 1. A feeding assembly is provided at the bottom of the inner side of the feeding hopper 2. A support foot 3 is provided at the bottom of the outer casing 1. Five conveyor belts 4 are provided, and the five conveyor belts 4 are distributed in a staggered manner. A drive motor 6 is provided on the front end face of the outer casing 1. A cooling fan 7 is fixedly installed on the side of the top of the feed hopper 2, and a ventilation box 8 is fixedly installed at the rear end of the outer casing 1. An air supply plate 9 is set on the inner side of the outer casing 1 above the conveyor belt 4. A discharge port 10 is opened at the bottom of the right end face of the outer casing 1. The high slow-release compound fertilizer is fed into the outer casing 1 through the feed hopper 2, and the feeding amount is controlled by the feeding component to make the fertilizer evenly spread on the conveyor belt 4. The conveying of multiple conveyor belts 4 increases the cooling time of the fertilizer, and the transfer of fertilizer falling on multiple conveyor belts 4 makes it easy to turn the fertilizer, ensuring the uniformity of cooling and improving the cooling efficiency.

[0024] Please see Figure 2 and Figure 4In this embodiment, the feeding assembly includes a rotating shaft 21, on the surface of which blades 22 are fixedly mounted. The blades 22 are arranged in a ring array. The front and rear ends of the rotating shaft 21 are rotatably connected to the two ends of the feeding hopper 2, respectively. A servo motor is provided at the front end of the feeding hopper 2. The output end of the servo motor is fixedly connected to the front end of the rotating shaft 21. The servo motor drives the rotating shaft 21 to rotate. The rotation of the multiple blades 22 controls the amount of fertilizer fed, preventing excessive fertilizer from accumulating on the conveyor belt 4, thereby spreading the fertilizer more evenly on the conveyor belt 4 and improving cooling efficiency.

[0025] Please see Figure 2 and Figure 4 In this embodiment, drive rollers are provided at both ends of the inner side of the conveyor belt 4. The front end of the drive roller is fixedly connected to the output end of the drive motor 6. The two ends of the drive roller are rotatably connected to the inner wall of the outer box 1. A guide block 41 is fixedly installed on the surface of the inner wall of the outer box 1. The guide block 41 has a triangular structure design. The bottom of the guide block 41 is in close contact with the conveyor belt 4, and the guide block 41 and the conveyor belt 4 correspond one-to-one. The drive motor 6 drives the rotation of the drive roller, which facilitates the control of the movement of the conveyor belt 4. The fertilizer can be moved synchronously. Multiple conveyor belts 4 allow the fertilizer to move left and right in the outer box 1. When the fertilizer falls on the upper conveyor belt 4, it is guided by the guide block 41, which can turn the fertilizer over and ensure the uniform cooling of the fertilizer.

[0026] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the output end of the cooling fan 7 is connected to the top of the ventilation box 8 through a pipe. The rear end of the air supply plate 9 is connected to the ventilation box 8. An air outlet groove is opened on the lower end face of the air supply plate 9. A discharge guide plate 11 is provided at the bottom of the outer casing 1. One end of the discharge guide plate 11 is adapted to the bottom of the conveyor belt 4, and the other end of the discharge guide plate 11 is adapted to the discharge port 10. The cooling fan 7 blows air, and the airflow enters multiple air supply plates 9 through the ventilation box 8, thereby blowing and cooling the fertilizer on the conveyor belt 4. Finally, after the fertilizer is cooled, it falls from the conveyor belt 4 onto the discharge guide plate 11 and slides out naturally from the discharge port 10.

[0027] During operation, the cooling fan 7 sends airflow into the ventilation box 8, allowing the air supply plate 9 to evenly distribute airflow within the outer casing 1. The high-slow-release compound fertilizer is fed into the outer casing 1 through the feed hopper 2. The servo motor drives the rotating shaft 21 to rotate, and the rotation of multiple blades 22 controls the amount of fertilizer fed, preventing excessive fertilizer from accumulating on the conveyor belt 4. This ensures that the fertilizer is evenly spread on the conveyor belt 4, improving cooling efficiency. As the conveyor belt 4 carries the fertilizer, the airflow blows onto the fertilizer surface for convenient cooling. The drive motor 6 drives the drive roller to rotate, facilitating the control of the movement of the conveyor belt 4 and allowing the fertilizer to move synchronously. Multiple conveyor belts 4 allow the fertilizer to move left and right within the outer casing 1. When the fertilizer falls from the upper conveyor belt 4, it is guided by the guide block 41, which can turn the fertilizer over, ensuring uniform cooling. Finally, after cooling, the fertilizer falls from the conveyor belt 4 onto the discharge guide plate 11 and naturally slides out from the discharge port 10.

[0028] Through the above steps, the high-slow-release compound fertilizer is fed into the outer casing 1 through the feed hopper 2, and the feeding amount is controlled by the feeding component, so that the fertilizer is evenly spread on the conveyor belt 4. The conveying of multiple conveyor belts 4 increases the cooling time of the fertilizer, and the transfer of fertilizer falling on multiple conveyor belts 4 makes it easy to turn the fertilizer, ensuring the uniformity of cooling and improving the cooling efficiency. This solves the problem that the existing cooling devices for the production of high-slow-release compound fertilizer have low cooling efficiency and the single-sided cooling method is prone to uneven cooling, which affects the cooling effect.
