Description

Technical Field

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

[0002] High-tower compound fertilizer coating technology significantly improves the slow-release properties, anti-caking properties, and stability of fertilizers by spraying coating materials onto the surface of the granules, making it a key process in modern compound fertilizer production. The coating technology forms a physical barrier by uniformly spraying a layer of functional material onto the surface of high-tower compound fertilizer granules, controlling the nutrient release rate. However, in traditional coating equipment, the bottom compound fertilizer granules may not be coated with the functional material, thus affecting the quality of subsequent compound fertilizer coating.

[0003] To overcome the above-mentioned defects, the existing technology (Chinese patent with publication number CN111454109A, publication date 2020-07-28) provides a coating device for high-tower compound fertilizer processing. The device includes a housing with an I-shaped top block on its upper surface, a first motor on the upper surface of the I-shaped top block, a coating liquid tank on the upper surface of the housing, a second motor and an air bladder on the lower surface of the housing, and a crankshaft and transmission rod at the output end of the second motor. This coating device for high-tower compound fertilizer processing uses the first motor to drive the rotating shaft and hollow rod to rotate, causing the stirring paddle and filter screen to rotate in opposite directions, thus stirring the compound fertilizer. Simultaneously, the rotating shaft drives the second rotating rod to rotate via a conveyor chain, causing the stirring blades to stir the coating liquid. The second motor drives the crankshaft to rotate, causing the air bladder to dry the inside of the conveying cylinder. At the same time, the spiral conveyor plates transport the coated compound fertilizer, saving manpower and resources and making it suitable for widespread application.

[0004] The aforementioned mechanism uses a rotating mechanism to stir the compound fertilizer, allowing it to fully contact the coating liquid and thus achieve coating treatment. However, in actual use, if too much material is fed, there may be a problem that too much compound fertilizer cannot fully contact the coating liquid, affecting the coating quality. Utility Model Content

[0005] The purpose of this invention is to provide a high-tower compound fertilizer coating device to solve the problem mentioned in the background art that traditional coating equipment may fail to coat the bottom compound fertilizer particles with functional materials, thereby affecting the subsequent coating quality of compound fertilizer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-tower compound fertilizer coating device, comprising a spray box, wherein inlets are provided on both the left and right sides of the top of the spray box, and an outlet is provided at the middle position of the bottom of the spray box; a quantitative feeding mechanism for controlling the feeding speed is provided at the upper end of the inside of the spray box, a guiding spray mechanism for controlling the feeding direction is provided at the middle position of the inside of the spray box, a stirring mechanism for assisting the compound fertilizer to contact the coating liquid is provided at the lower end of the inside of the spray box, and an automatic discharge mechanism is provided inside the outlet.

[0007] Furthermore, the guiding spray mechanism includes a guide plate, which is located in the middle of the spray box, and spray heads are provided at both the front and rear ends of the bottom of the guide plate.

[0008] Furthermore, the quantitative feeding mechanism includes a first drive motor, which is fixedly connected to the middle position at the top of the spray box. A disc is installed on the output end of the first drive motor through a connecting rod. Rotary rods are rotatably connected to both the front and rear ends of the spray box, and a baffle plate is provided at one end between the rotating rods. The baffle plates are all located at the bottom of the feed inlet.

[0009] Furthermore, the upper surface of the disk is inclined, and the side of the baffle plate near the connecting rod is positioned above the disk.

[0010] Furthermore, a first torsion spring is wound around the outer side of the rotating rod, and the shielding plate and the rotating rod form an elastic structure through the first torsion spring.

[0011] Furthermore, the stirring mechanism includes a stirring rod, which is fixedly connected to the outside of the connecting rod. The output end of the first drive motor is connected to the connecting rod. Mounting brackets are installed on both the left and right sides of the lower end of the spray box. A connecting shaft is rotatably connected inside the mounting bracket. A fan blade is fixedly connected to the outside of the connecting shaft. The top end of the connecting shaft passes through the mounting bracket and is wound with a second torsion spring.

[0012] Furthermore, the automatic feeding mechanism includes a second drive motor, which is fixedly connected to the side of the discharge port. The output end of the second drive motor extends into the interior of the discharge port and is fitted with a limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The output of the first drive motor rotates and drives the disc to rotate. When the disc is rotated, the highest and lowest points on the side of the disc will contact the two baffles respectively because the surface of the disc is inclined. When the highest point of the disc contacts the baffle, the side of the baffle closest to the disc is lifted up, and the other side of the baffle separates from the bottom of the feed inlet and is inclined, so that the material can enter the interior of the spray box from the feed inlet and come into contact with the coating liquid. The material feeding amount can be controlled by controlling the angle of the baffle.

[0015] Furthermore, after the compound fertilizer enters the spray box, it is guided and diverted by the guide plate, allowing the compound fertilizer to fall to a position closer to the spray head, so as to better contact the coating liquid with the compound fertilizer. Through the cooperation of the guide plate and the spray head, the compound fertilizer can make more full contact with the coating liquid, thus improving the coating quality.

[0016] Furthermore, the output of the second drive motor rotates and drives the limiting plate to rotate. When the limiting plate is not rotating, it can block the bottom of the discharge port, prolonging the contact time between the compound fertilizer particles and the coating liquid. When the limiting plate rotates, the compound fertilizer particles will fall from the discharge port, thus achieving the discharge of the compound fertilizer particles.

[0017] 2. The output end of the first drive motor rotates and drives the connecting rod to rotate. When the connecting rod rotates, it will synchronously drive the stirring rod to rotate. When the stirring rod rotates, it will continuously stir the compound fertilizer, causing the compound fertilizer to be turned over, so that the compound fertilizer that has not been in contact with the coating liquid will be turned over and come into contact with the coating liquid.

[0018] Furthermore, the stirring rod strikes the fan blades as it rotates, causing the blades to deflect at an angle. This allows the fan blades to assist in stirring the compound fertilizer on the sides, increasing the stirring area and extending the contact time between the compound fertilizer and the coating liquid, thus ensuring the coating quality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figures 1-4 and Figure 6 The technical solution shown addresses the problem that traditional coating equipment may fail to coat the bottom compound fertilizer granules with functional materials, thus affecting the subsequent coating quality. This high-tower compound fertilizer coating device discloses a quantitative feeding mechanism, including a spray box 1. The spray box 1 has inlets 2 on both the left and right sides of its top, and an outlet 3 at the center of its bottom. A quantitative feeding mechanism for controlling the feeding speed is located at the upper part of the spray box 1, and a guiding spray mechanism for controlling the feeding direction is located at the center of the spray box 1. The guiding spray mechanism includes a guide plate 9, which is positioned in the center of the spray box 1. At the location, spray heads 10 are provided at both the front and rear ends of the bottom of the guide plate 9; the quantitative feeding mechanism includes a first drive motor 4, and the first drive motor 4 is fixedly connected to the middle position of the top of the spray box 1. The output end of the first drive motor 4 is mounted with a disc 5 through a connecting rod 11. Rotating rods 7 are rotatably connected to both the front and rear ends of the spray box 1, and a baffle plate 6 is provided at one end between the rotating rods 7. The baffle plates 6 are all located at the bottom of the feed inlet 2; the upper surface of the disc 5 is inclined, and the side of the baffle plate 6 near the connecting rod 11 is located above the disc 5; a first torsion spring 8 is wound around the outside of the rotating rod 7, and the baffle plate 6 and the rotating rod 7 form an elastic structure through the first torsion spring 8.

[0028] In this example, such as Figure 2As shown, materials are added to the interior of the spray box 1 through the feed inlet 2. The feeding speed of the compound fertilizer can be controlled by the quantitative feeding mechanism, so that the compound fertilizer inside the spray box 1 can have more sufficient contact with the coating liquid, thereby improving the coating quality of the compound fertilizer. After feeding through the feed inlet 2, the output end of the first drive motor 4 rotates and drives the disc 5 to rotate. When the disc 5 is driven to rotate, since the surface of the disc 5 is inclined, the highest and lowest points on the side of the disc 5 will contact the two baffle plates 6 respectively. When the highest point of the disc 5 contacts the baffle plate 6, the baffle plate 6 is close to the disc 5. The side is lifted up, and the other side of the baffle plate 6 separates from the bottom of the feed inlet 2 and is inclined, so that the material can enter the interior of the spray box 1 from the feed inlet 2 and come into contact with the coating liquid. The greater the inclination angle of the baffle plate 6, the larger the gap between the feed inlet 2 and the baffle plate 6, and the more material is fed per unit time, and vice versa. When the lowest point of the disc 5 contacts the baffle plate 6, the side of the baffle plate 6 near the disc 5 tilts downward due to its own weight, and the top of the baffle plate 6 fits against the bottom of the feed inlet 2, blocking the feed inlet 2 and reducing the amount of material entering, thereby controlling the amount of compound fertilizer entering the spray box 1. Figure 2 As shown, the weight of the side of the baffle plate 6 closest to the disk 5 is greater than the weight of the other side of the baffle plate 6. Simultaneously, under the action of the first torsion spring 8, when the disk 5 is not supported by the baffle plate 6, the angle of the side of the baffle plate 6 closest to the disk 5 deflects downwards, while the other side of the baffle plate 6 tilts up and blocks the bottom of the feed inlet 2; Figure 3 As shown, rotating rods 7 are installed at both the front and rear ends of the baffle plate 6, and a first torsion spring 8 is wound around the outer side of the rotating rod 7. The first torsion spring 8 allows the baffle plate 6 to automatically return to its original angle when it is not supported by the disc 5, thus enabling the baffle plate 6 to stably seal the bottom of the feed inlet 2 without external force, preventing compound fertilizer from entering the interior of the spray box 1; Figure 2 and Figure 3 As shown, after the compound fertilizer enters the interior of the spray box 1, it is guided and diverted by the guide plate 9, so that the compound fertilizer falls to a position closer to the spray head 10, so as to better contact the coating liquid and the compound fertilizer. Through the cooperation of the guide plate 9 and the spray head 10, the compound fertilizer can come into more full contact with the coating liquid, thus improving the coating quality.

[0029] Example 2: Figures 1-3 and Figure 5The technical solution shown addresses the problem that excessive feed may prevent the compound fertilizer from fully contacting the coating liquid, thus affecting the coating quality. The high-tower compound fertilizer coating device discloses a stirring mechanism. The lower end of the spray box 1 is equipped with a stirring mechanism to facilitate contact between the compound fertilizer and the coating liquid. The stirring mechanism includes a stirring rod 12, which is fixedly connected to the outside of a connecting rod 11. The output end of the first drive motor 4 is connected to the connecting rod 11. Mounting frames 13 are installed on both the left and right sides of the lower end of the spray box 1. A connecting shaft 16 is rotatably connected inside the mounting frame 13. A fan blade 14 is fixedly connected to the outside of the connecting shaft 16. The top end of the connecting shaft 16 passes through the mounting frame 13 and is wound with a second torsion spring 15.

[0030] In this example, such as Figure 3 As shown, the output of the first drive motor 4 rotates, driving the connecting rod 11 to rotate. When the connecting rod 11 rotates, it synchronously drives the stirring rod 12 to rotate. The stirring rod 12, in turn, continuously agitates the compound fertilizer, causing it to tumble and allowing any fertilizer not currently in contact with the coating solution to come into contact with it. Figure 5 As shown, when the stirring rod 12 rotates, it strikes the fan blade 14, causing the fan blade 14 to deflect at an angle. The fan blade 14 then assists in agitating the compound fertilizer on the side, thereby increasing the stirring area and extending the contact time between the compound fertilizer and the coating liquid, ensuring coating quality. Figure 5 As shown, the fan blade 14 is connected to the connecting shaft 16 via the second torsion spring 15. Therefore, after the fan blade 14 is pushed to deflect at an angle, it will automatically reset by the elastic force of the second torsion spring 15, so that the angle returns to the initial state, thereby making the internal compound fertilizer particles more thoroughly stirred.

[0031] Example 3: Figure 1 and Figure 2 The technical solution shown addresses the problem that some compound fertilizer may be discharged from the outlet 3 before it comes into contact with the coating liquid during spraying: the high-tower compound fertilizer coating device discloses an automatic discharge mechanism, which is installed inside the outlet 3; the automatic discharge mechanism includes a second drive motor 18, which is fixedly connected to the side of the outlet 3, and the output end of the second drive motor 18 extends into the interior of the outlet 3 and is fitted with a limiting plate 17.

[0032] In this example, such as Figure 2As shown, the output end of the second drive motor 18 rotates and drives the limiting plate 17 to rotate. When the limiting plate 17 does not rotate, it can block the bottom of the discharge port 3, prolonging the contact time between the compound fertilizer particles and the coating liquid. When the limiting plate 17 rotates, the compound fertilizer particles will fall from the discharge port 3, realizing the discharge of the compound fertilizer particles.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
