Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, and in particular to a vibrating screen device for preventing clogging of compound fertilizer granules. Background Technology

[0002] Compound fertilizer granules are granular fertilizers made from multiple nutrients such as nitrogen, phosphorus, and potassium through physical mixing or chemical reaction. They are characterized by balanced nutrients, easy storage and transportation, and wide applicability, and are widely used in agricultural production. Their particle diameter is between 1 and 4 millimeters. Different crops and growth stages have different requirements for particle size. Therefore, it is necessary to control the particle size through screening process to ensure uniform nutrient release and fertilization efficiency.

[0003] During the screening process, the particles need to be separated by a screen. Qualified particles are used for packaging and sales, while unqualified large particles need to be crushed again. However, when traditional screening devices process compound fertilizer particles with high viscosity or high moisture content, the particles stick together or are attracted by static electricity through friction with the screen, causing the screen to become clogged, which affects the screening efficiency and continuous operation of the equipment.

[0004] Existing compound fertilizer granule screening devices use a motor to drive the screen to rotate and screen the granules in layers. Although some devices are equipped with inclined screens to increase the tilt angle and reduce clogging, which can avoid minor clogging to some extent, after long-term operation, large particles will accumulate on the screen surface and generate static electricity by rubbing against small particles. This makes it impossible to solve the problem of large particles being attracted to the screen by static electricity. Operators need to frequently stop the machine to disassemble the screen for manual cleaning, which not only increases labor intensity but also causes production interruption, reduces screening efficiency, and affects production safety and economy.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a vibrating screen device for screening compound fertilizer particles and preventing clogging, including a screening box 1 and a workbench 2. The screening box 1 is provided with a vibrating screening mechanism 3, which is used to screen out compound fertilizer particles with qualified diameter. The bottom inner side of the workbench 2 is provided with a lifting mechanism 4, which is used to lift the left side of the screening box 1 to facilitate the removal of compound fertilizer particles with larger diameter.

[0034] The vibrating screening mechanism 3 includes a screen cylinder 301, which is rotatably connected inside the screening box 1. A feeding assembly 302 is provided at the top left end of the screen cylinder 301. The feeding assembly 302 includes a support frame 3021, which is fixedly connected to the lower left side of the screening box 1. A feeding hopper 3022 is fixedly connected to the top of the support frame 3021. Multiple support rods 303 are fixedly connected at equal intervals inside the screen cylinder 301. A dustproof box 304 is fixedly connected to the adjacent end of each of the multiple support rods 303. A vibrating motor 305 is fixedly connected inside the dustproof box 304. A drive assembly 306 is provided at the top right side of the screen cylinder 301. A discharge assembly 307 is provided at the bottom inner side of the screening box 1. The discharge assembly 307 includes a collecting plate 3071, which is fixedly connected to the lower inner side of the screening box 1. A conical discharge cylinder 3072 is fixedly connected to the bottom of the collecting plate 3071.

[0035] Specifically, in the vibrating screening mechanism 3, the screen cylinder 301 is rotatably connected to the inside of the screening box 1. The feeding assembly 302 at the top left end of the cylinder is used to supply the particles to be screened. The support frame 3021 is fixed in the lower middle part of the left side of the screening box 1. The top feeding hopper 3022 receives the compound fertilizer particles and guides them into the screen cylinder 301. Multiple support rods 303 inside the screen cylinder 301 are equidistantly distributed, and their adjacent ends are jointly fixed to the dustproof box 304. When the vibrating motor 305 inside the dustproof box 304 is powered on, it generates vibration, which is transmitted to the screen cylinder 301 through the support rods 303, causing the screen cylinder 301 to generate high frequency. With slight vibration, the screen cylinder 301 rotates under the action of the drive assembly 306. The compound fertilizer granules to be screened fall into the screen cylinder 301 from the feed hopper 3022. As the screen cylinder 301 rotates, it is carried to a higher position and then falls. At the same time, it is vibrated by the vibration motor 305. The granules jump on the screen mesh on the inner wall of the screen cylinder 301. Particles with a qualified diameter pass through the screen mesh and fall onto the collection plate 3071 at the bottom of the inner side of the screening box 1, and are discharged through the conical discharge cylinder 3072. Larger diameter particles move to the right along the inner wall of the screen cylinder 301 and are finally discharged through the lifting mechanism 4. The sieve cylinder 301 discharges from the right end. Through the rotation of the sieve cylinder 301 and the vibration of the vibrating motor 305, the compound fertilizer granules are stratified and clogging-proof, preventing granules from accumulating on the screen and affecting screening efficiency. When it is necessary to remove large granules remaining in the sieve cylinder 301, the lifting mechanism 4 at the bottom inner side of the workbench 2 is activated, raising the left side of the screening box 1 and tilting it at a certain angle. At this time, large granules that have not been discharged in time in the sieve cylinder 301 slide to the left under gravity and are quickly discharged from the left end of the sieve cylinder 301, facilitating the cleaning of residual granules and reducing manual operation. To enhance strength and improve equipment maintenance efficiency, in the vibrating screening mechanism 3, the feeding component 302 ensures orderly feeding of particles, the support rod 303 and the dustproof box 304 fix the vibrating motor 305 and transmit vibration energy, the drive component 306 provides rotational power, and the discharge component 307 collects qualified particles and discharges them, so that the compound fertilizer particles are screened under the dual action of rotation and vibration of the screen cylinder 301, which not only improves the screening efficiency, but also prevents particles from clogging the screen through vibration. The setting of the lifting mechanism 4 further optimizes the ease of operation of the equipment and ensures that the screening process is continuous and efficient.

[0036] Reference Figure 1 , Figure 4 and Figure 5The lifting mechanism 4 includes a fixed carrier plate 401, which is fixedly connected to the bottom left end of the inner side of the workbench 2. A diagonal brace plate 402 is fixedly connected to the top of the fixed carrier plate 401. A bearing plate 403 is fixedly connected to the bottom of the screening box 1. Multiple hinges 404 are fixedly connected to the right side of the bearing plate 403. The bottom of the multiple hinges 404 is fixedly connected to the top right side of the workbench 2. Two portal rods 405 are fixedly connected to the bottom left side of the bearing plate 403 and the top of the diagonal brace plate 402. Hydraulic rods 406 are installed between the two portal rods 405 on the front side and between the two portal rods 405 on the rear side. A defective product removal component 407 is provided on the right side of the screen cylinder 301. The defective product removal component 407 includes a rubber cover 4071. A handle 4072 is fixedly connected to the right side of the rubber cover 4071. A sealing groove 4073 is opened on the left side of the rubber cover 4071. The sealing groove 4073 is engaged with the right end of the screen cylinder 301.

[0037] Specifically, the fixed carrier plate 401 of the lifting mechanism 4 is fixed to the bottom left end of the inner side of the workbench 2. The inclined support plate 402 at the top of the carrier plate 403 forms a support structure with the bottom left side of the carrier plate 403. The right side of the carrier plate 403 is connected to the top right side of the workbench 2 through multiple hinges 404, allowing the carrier plate 403 to rotate around the hinges 404. The bottom left side of the carrier plate 403 and the portal rod 405 at the top of the inclined support plate 402 provide mounting points for the hydraulic rod 406. The two ends of the hydraulic rod 406 on the front and rear sides are respectively hinged to the corresponding portal rods 405. When the piston rod of the hydraulic rod 406 extends, it pushes the left side of the carrier plate 403 to move upward. Due to the rotation restriction of the hinge 404, the screening box 1 moves with the carrier plate 403 around the hinge 404. Rotating the clockwise direction lifts the left side of the screening box 1, facilitating the removal of larger-diameter compound fertilizer granules from the screen cylinder 301. In the defective product removal assembly 407 on the right side of the screen cylinder 301, the rubber cover 4071 can be manually operated via the handle 4072 on the right side. Its left-side sealing groove 4073 engages with the right end of the screen cylinder 301, forming a detachable sealing connection. During normal screening, the rubber cover 4071 seals the right end of the screen cylinder 301 to prevent granule leakage. When it is necessary to clean the large defective granules remaining in the screen cylinder 301, the operator pulls the rubber cover 4071 from the right end of the screen cylinder 301 using the handle 4072, opening the discharge port. The remaining large granules are discharged from the discharge port on the right end of the screen cylinder 301 under gravity and vibration. Subsequently, the hydraulic rod 406 of the lifting mechanism 4 retracts, causing the left side of the screening box 1 to descend to its initial position, restoring the screen cylinder 301 to a horizontal state. Through the extension and retraction of the hydraulic rod 406 and the rotation of the hinge 404, the lifting mechanism 4 achieves the angle adjustment function of the screening box 1, making it easier for large particles in the screen cylinder 301 to be discharged under gravity. The locking structure between the rubber cover 4071 and the screen cylinder 301 ensures sealing during normal screening and facilitates quick opening for cleaning operations. The coordinated work of the lifting mechanism 4 and the defective product removal component 407 optimizes the defective product handling process during the screening of compound fertilizer granules, reduces manual intervention, and improves the automation level and production efficiency of the equipment. At the end, the operator first removes the rubber cover 4071 using handle 4072, then activates the hydraulic rod 406 to extend its piston rod, causing the left side of the screening box 1 to gradually rise. As the tilt angle of the screening box 1 increases, large defective particles inside the screen cylinder 301 slide to the right along the inclined inner wall of the screen cylinder 301 and are discharged from the open right end outlet to the designated collection container. After discharge, the hydraulic rod 406 retracts, the screening box 1 returns to the horizontal position, and the operator re-locks the rubber cover 4071 onto the right end of the screen cylinder 301, and the equipment can be put back into screening operation. Through this process, the lifting mechanism 4 and the defective product removal component 407 achieve efficient cleaning of defective products and rapid reset of the equipment during the screening of compound fertilizer particles.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The drive assembly 306 includes a driven gear 3061, which is fixedly connected to the outer right side of the screen cylinder 301. A mounting plate 3062 is fixedly connected to the top right side of the screening box 1. A drive motor 3063 is fixedly connected to the top right side of the mounting plate 3062. A drive gear 3064 is fixedly connected to the output end of the drive motor 3063. The drive gear 3064 meshes with the driven gear 3061. The discharge assembly 307 also includes a telescopic hose 3073, the top end of which is fixedly connected to the bottom of the conical discharge cylinder 3072. A connecting flange 3074 is fixedly connected to the bottom of the telescopic hose 3073. The feeding assembly 302 also includes a dust cover 3023, the rear side of which is rotatably connected to the top rear end of the feeding hopper 3022.

[0039] Specifically, in the drive assembly 306, the driven gear 3061 is welded to the outside right side of the screen cylinder 301. The mounting plate 3062 on the top right side of the screening box 1 provides a mounting base for the drive motor 3063. The drive gear 3064 at the output end of the drive motor 3063 meshes with the driven gear 3061. When the drive motor 3063 is powered on, the drive gear 3064 rotates accordingly, driving the driven gear 3061 to rotate through the meshing force, thereby causing the screen cylinder 301 to rotate around its own axis. Through the transmission cooperation of the drive motor 3063, drive gear 3064, and driven gear 3061, the screen cylinder 301 achieves stable rotation, providing a motion basis for the screening of compound fertilizer granules. The collection plate 3071 of the discharge assembly 307 is fixed in the lower middle part of the inner side of the screening box 1, receiving qualified compound fertilizer granules that have passed through the screen after screening by the screen cylinder 301. The granules slide down along the collection plate 3071 to the conical discharge cylinder 3072. The bottom of the conical discharge cylinder 3072 is connected to the telescopic hose 3073. The length can be adjusted according to actual needs. The bottom connecting flange 3074 is used to connect to the external conveying pipeline. Qualified particles are conveyed to the designated storage or processing position through the conical discharge cylinder 3072, the telescopic hose 3073, and the connecting flange 3074. The combination of the collecting plate 3071, the conical discharge cylinder 3072, the telescopic hose 3073, and the connecting flange 3074 achieves the effect of orderly collection and flexible conveying of qualified particles. The support frame 3021 of the feeding assembly 302 is fixed on the left side of the screening box 1. The feed hopper 3022 at the bottom side and top receives and screens compound fertilizer granules. The dust cover 3023, which is rotatably connected to the top rear end of the feed hopper 3022, can be flipped upwards and opened during feeding to allow the granules to enter the feed hopper 3022 smoothly. After feeding, the dust cover 3023 flips downwards and closes to cover the top opening of the feed hopper 3022, preventing dust generated during screening from overflowing. Through the opening and closing cooperation of the feed hopper 3022 and the dust cover 3023, the convenience of feeding and the dust prevention effect of the working environment are achieved.

[0040] Working principle: Compound fertilizer granules enter the vibrating screening mechanism 3 through the feeding assembly 302. The support frame 3021, fixed to the lower left side of the screening box 1, provides support for the feeding hopper 3022. The compound fertilizer granules to be screened are poured in through the top opening of the feeding hopper 3022 and guided into the screen cylinder 301. After feeding, the dust cover 3023, which is rotatably connected to the top rear end of the feeding hopper 3022, flips down and closes, with its edge tightly fitting the top opening of the feeding hopper 3022 to prevent dust generated during screening from overflowing, achieving a dust sealing effect in the feeding process. After the vibrating screening mechanism 3 is started, the drive assembly 306 and the vibrating motor 305 work together to achieve granule screening. The mounting plate 3062 is fixed to the top right side of the screening box 1. This provides a stable mounting base for the drive motor 3063. The drive gear 3064 at the output end of the drive motor 3063 meshes with the driven gear 3061 fixed on the right side of the outside of the screen cylinder 301. When the drive motor 3063 is powered on, the drive gear 3064 rotates, driving the driven gear 3061 through the meshing force, causing the screen cylinder 301 to rotate continuously around its own axis. At the same time, the support rods 303 evenly distributed inside the screen cylinder 301 fix the dustproof box 304 at the center position of the screen cylinder 301. After the vibrating motor 305 inside the dustproof box 304 is powered on, it generates high-frequency micro-amplitude vibration. The vibration energy is evenly transmitted to the screen cylinder 301 through the support rods 303. The compound fertilizer particles entering the screen cylinder 301 are carried to a higher position as the screen cylinder 301 rotates. Under the influence of gravity and vibration from the vibrating motor 305, qualified particles fall and jump on the screen inside the screen cylinder 301. Particles with a diameter smaller than the screen mesh pass through the screen and fall onto the collecting plate 3071 at the bottom of the inner side of the screening box 1. They then slide down the inclined surface of the collecting plate 3071 to the conical discharge cylinder 3072. The telescopic hose 3073 connected to the bottom of the conical discharge cylinder 3072 can be adjusted in length according to actual needs. The connecting flange 3074 at its bottom is used to connect to an external conveying pipeline. Qualified particles are conveyed to the designated storage or processing position via the conical discharge cylinder 3072, telescopic hose 3073, and connecting flange 3074. Larger diameter particles move to the right along the inner wall of the screen cylinder 301 and are temporarily retained in the screen cylinder 301. Within the screen 1, the rotation of the screen cylinder 301 and the vibration of the vibrating motor 305 work together to achieve layered screening and anti-clogging of compound fertilizer granules, preventing granules from accumulating on the screen and affecting screening efficiency. When it is necessary to clean the large defective granules remaining in the screen cylinder 301, the lifting mechanism 4 is activated. The fixed carrier plate 401 is pre-fixed to the bottom left end of the inner side of the workbench 2. The inclined support plate 402 at the top of the carrier plate 403 and the bottom left side of the bottom support plate 403 of the screening box 1 form an initial support structure. The right side of the carrier plate 403 is connected to the top right side of the workbench 2 through multiple hinges 404, giving the carrier plate 403 the freedom to rotate around the hinges 404. The portal rod 405 at the bottom left side of the carrier plate 403 and the top of the inclined support plate 402 provides a mounting point for the hydraulic rod 406.The two ends of the hydraulic rods 406 on the front and rear sides are respectively hinged to the corresponding portal rods 405. When the piston rod of the hydraulic rod 406 extends, it pushes the left side of the bearing plate 403 to move upward. Due to the rotation restriction of the hinge 404, the screening box 1 rotates clockwise around the hinge 404 with the bearing plate 403, realizing the lifting of the left side of the screening box 1. Before starting the lifting mechanism 4, the operator first pulls the rubber cover 4071 from the right end of the screen cylinder 301 through the handle 4072. The sealing groove 4073 on the left side of the rubber cover 4071 is disengaged from the right end of the screen cylinder 301, opening the discharge port at the right end of the screen cylinder 301. As the left side of the screening box 1 gradually rises, large particles that are not discharged in time in the screen cylinder 301 slide to the right side along the inclined inner wall of the screen cylinder 301 under the action of gravity, and are discharged from the opened right end discharge port to the designated collection container. After the discharge is completed, the hydraulic rod 406 retracts, driving the left side of the screening box 1 to descend to the initial position, so that the screen cylinder 301 returns to water. In the flat state, the operator re-clamps the rubber cover 4071 onto the right end of the screen cylinder 301. Its sealing groove 4073 is tightly embedded in the right edge of the screen cylinder 301, forming a sealed connection to prevent particle leakage during the next screening process. Throughout the screening process, the feeding component 302 ensures orderly particle feeding and controls dust overflow; the drive component 306, in conjunction with the vibration motor 305, realizes the rotation and vibration of the screen cylinder 301, completing particle screening and anti-clogging; the discharge component 307 realizes the collection and flexible conveying of qualified particles; the lifting mechanism 4 and the defective product removal component 407 work together to efficiently clean large defective particles from the screen cylinder 301 and reset the equipment. All components cooperate through mechanical transmission, sealing connections, and angle adjustments to form a complete workflow from feeding, screening, discharge to defective product cleaning, improving the efficiency of compound fertilizer particle screening and the degree of equipment automation, reducing manual intervention, and ensuring continuous and stable screening operations.
