Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer screening technology, and in particular to a fertilizer granule screening vibrator. Background Technology
[0002] A screening vibrator is a mechanical device that uses vibration to screen materials. It is widely used in industries such as mining, chemical, building materials, food, and pharmaceuticals to classify, screen, or remove impurities from granular and powdery materials. In order to enable materials to pass through the screen quickly through strong vibration and improve screening efficiency, a fertilizer granule screening vibrator is required.
[0003] Fertilizer granule screening vibrators can be divided into several types, including single-layer vibrating screens, multi-layer vibrating screens, and circular vibrating screens. The appropriate type of screening vibrator can be selected based on the different needs of fertilizer production and the different characteristics of the granules. Among them, the single-layer vibrating screen is the most basic screening equipment, typically used for screening materials with relatively uniform particle sizes. It consists of a screen and a single vibrating mechanism, suitable for handling screening needs with fewer layers.
[0004] Existing screening vibrators typically require large drive units and heavy vibration mechanisms during the screening process, which not only occupies a significant amount of production space but also increases the overall size of the equipment. Traditional screening equipment designs also fail to adequately address the self-cleaning issue of the screens; the screen surface frequently becomes clogged due to material accumulation, leading to decreased screening efficiency. This necessitates frequent screen cleaning by operators, increasing the cost and time associated with manual intervention. Therefore, traditional screening vibrators have significant shortcomings in saving space and improving screen cleaning efficiency, urgently requiring optimized design. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a fertilizer granule screening vibrator, which aims to improve the problem of the large size of the drive device in traditional screens during screening.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fertilizer granule screening vibrator, comprising a housing, a limiting component provided inside the housing, a frame slidably connected inside the housing, a support plate fixedly connected to one side of the housing, a screening component provided on one side of the support plate, and a discharge pipe fixedly connected to the bottom of the housing.
[0007] The screening assembly includes a drive gear, which is rotatably connected inside a support plate. A double-sided rack is slidably connected inside the support plate. A connecting rod is fixedly connected to one side of the double-sided rack, and one end of the connecting rod is connected to the outer wall of the frame. A screen is fixedly connected inside the frame. A driven gear is rotatably connected inside the support plate. A sector gear is fixedly connected inside the driven gear. The sector gear meshes with the double-sided rack. The driven gear meshes with the drive gear. A drive assembly is provided on the other side of the support plate.
[0008] As a further description of the above technical solution:
[0009] The limiting component includes a guide rail, the outer wall of which is fixedly connected to the inside of the housing, and one side of the frame is slidably connected to the inside of the guide rail.
[0010] As a further description of the above technical solution:
[0011] The drive assembly includes a motor, the outer wall of which is fixedly connected to the other side of the support plate, and the output end of the motor is connected to the drive gear.
[0012] As a further description of the above technical solution:
[0013] A support rod is fixedly connected inside the housing, and a support rod is fixedly connected to the top of the support rod.
[0014] As a further description of the above technical solution:
[0015] The support rod is internally connected to a limiting plate, and the top of the limiting plate is fixedly connected to bristles.
[0016] As a further description of the above technical solution:
[0017] The support rod has a telescopic rod inside, and a spring is sleeved on the outer wall of the telescopic rod.
[0018] As a further description of the above technical solution:
[0019] One end of the telescopic rod and the spring are both fixedly connected to the bottom of the limiting plate, and the other end of the telescopic rod and the spring are both fixedly connected to the inside of the support rod.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the driving gear first drives the sector gear to rotate through the driven gear. The teeth of the sector gear mesh with the double-sided rack, causing the double-sided rack to move parallel on the support plate. The sector gear moves up and down to drive the double-sided rack to move back and forth, thus reducing the area occupied. This solves the problem of the large size of the driving device in traditional screens during screening and improves the practicality of the screening vibrator.
[0022] 2. In this utility model, the brush bristles are supported by the tension of the spring, so that the brush bristles can always stick to the bottom of the screen. As the screen moves back and forth, it contacts the brush bristles to perform self-cleaning, achieving the effect of self-cleaning the screen while screening. This solves the problem that the screen mesh needs to be cleaned frequently by the operator if it is blocked, and improves the convenience of the screening vibrator. Attached Figure Description

[0030] 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.
[0031] Reference Figures 1-4This utility model provides an embodiment of a fertilizer granule screening vibrator, comprising a housing 1. A limiting component is provided inside the housing 1 to restrict the movement range of a frame 4, preventing excessive movement or deviation from its designed trajectory and ensuring the stability of the screening process. The frame 4 is slidably connected inside the housing 1, and its movement is guided by the limiting component. A screen 5 is fixedly connected inside the frame 4 for screening fertilizer granules. A support plate 6 is fixedly connected to one side of the housing 1. The support plate 6 is a structural component supporting the entire screening system, and a screening component is provided on one side of the support plate 6 to realize the reciprocating motion of the screen 5 and granule screening. A discharge pipe 2 is fixedly connected to the bottom of the housing 1 for collecting and outputting the screened granules for subsequent processing.
[0032] The screening assembly includes a drive gear 8, which is rotatably connected inside the support plate 6 and drives the entire screening system. The drive gear 8 drives the driven gear 11 to rotate via gear transmission, thereby moving the screening system. A double-sided rack 9 is slidably connected inside the support plate 6, and connecting rods 10 are fixedly connected to both sides of the double-sided rack 9. The connecting rods 10 are connected to the outer wall of the frame 4, and the frame 4 achieves the screening operation of the screen 5 through the reciprocating left and right movement of the double-sided rack 9. The left and right movement of the double-sided rack 9 is driven by the meshing between the teeth of the sector gear 12 and the double-sided rack 9, ensuring the continuous operation of the screening process. A sector gear 12 is fixedly connected inside the driven gear 11, and the teeth of the sector gear 12 mesh with the double-sided rack 9. Through their up-and-down cooperation, the double-sided rack 9 is driven to reciprocate left and right, thereby causing the screen 5 to vibrate continuously and achieve the screening of fertilizer particles. A drive assembly is provided on the other side of the support plate 6. The drive assembly includes a motor 7, which is connected to the drive gear 8 through its output end. The motor 7 drives the drive gear 8 to realize the operation of the entire screening vibrator. The limiting assembly includes a guide rail 3, whose outer wall is fixedly connected to the inside of the housing 1. The guide rail 3 provides guidance for the sliding of the frame 4, ensuring that the frame 4 can move smoothly inside the housing 1. One side of the frame 4 is slidably connected to the inside of the guide rail 3, allowing the frame 4 to move smoothly back and forth inside the housing 1, thereby promoting the screening action of the screen 5.
[0033] Specifically, the output of motor 7 drives the drive gear 8 to rotate via a transmission shaft. The drive gear 8 transmits power through meshing with the driven gear 11, thereby driving the rotation of the sector gear 12. The teeth of the sector gear 12 precisely mesh with the double-sided rack 9, forming a highly efficient power transmission system, which allows the double-sided rack 9 to move parallel to the horizontal plane on the support plate 6. Through the precise up-and-down cooperation of the sector gear 12 and the double-sided rack 9, the double-sided rack 9 is driven to reciprocate left and right, thus achieving uniform processing of fertilizer during the screening process. At the same time, fertilizer is fed into the equipment through the feed port at the top of the shell 1. The double-sided rack 9, through the action of the connecting rod 10, drives the frame 4 to reciprocate left and right within a limited space under the guidance of the guide rail 3. Through this ingenious design, the screen 5 fixed on the frame 4 continuously screens the fertilizer during the reciprocating motion, effectively separating fertilizer particles of different sizes.
[0034] Reference Figure 5 A support rod 13 is fixedly connected inside the housing 1. The function of the support rod 13 is to provide stable support and ensure that the entire structure remains stable during operation. A support rod 14 is fixedly connected to the top of the support rod 13. The support rod 14 is used to bear and support the movement of the limiting plate 15. Its stability is crucial to the normal operation of the limiting plate 15. The limiting plate 15 is slidably connected inside the support rod 14. The function of the limiting plate 15 is to control the operating range of the entire screening system and prevent excessive movement of components or deviation from the design trajectory. A brush bristle 16 is fixedly connected to the top of the limiting plate 15. The brush bristle 16 cleans the screen 5 by contacting the screen 5, preventing the screen 5 from clogging and ensuring the smooth operation of the screening process. A telescopic rod 17 is provided inside the support rod 14. The function of the telescopic rod 17 is to adjust the position of the limiting plate 15 by extending and retracting to ensure that the brush bristle 16 can always be in contact with the screen 5. A spring 18 is fitted onto the outer wall of the telescopic rod 17. The function of the spring 18 is to provide elasticity, ensuring that the telescopic rod 17 can extend and retract as needed, and to keep the bristles 16 at the bottom of the screen 5 through its elasticity, preventing gaps between the bristles 16 and the screen 5 from affecting the cleaning effect. One end of both the telescopic rod 17 and the spring 18 is fixedly connected to the bottom of the limiting plate 15, ensuring that the tension of the spring 18 can effectively support the movement of the limiting plate 15. The other end of both the telescopic rod 17 and the spring 18 is fixedly connected to the inside of the support rod 14, ensuring a stable fit between the support rod 14 and the telescopic rod 17, achieving continuous contact between the bristles 16 and the screen 5, thereby achieving the self-cleaning effect of the screen 5.
[0035] Specifically, during the reciprocating movement of the screen 5, the screen 5 maintains continuous contact with the bristles 16. The bristles 16 are precisely positioned within the support rod 14 by the limiting plate 15, ensuring that the bristles 16 always remain in the correct position. Supported by the tension of the spring 18, the bristles 16 are stably attached to the bottom of the screen 5, preventing gaps between the bristles 16 and the screen 5 and ensuring the durability and uniformity of the cleaning effect. As the screen 5 reciprocates in the left-right direction, the bristles 16, through continuous contact, automatically remove debris and accumulated particles from the surface of the screen 5, achieving the self-cleaning function of the screen 5.
[0036] Working principle: When using this fertilizer granule screening vibrator, the output end of the motor 7 first drives the drive gear 8 to rotate. Then, the drive gear 8 drives the sector gear 12 to rotate through the driven gear 11. The teeth of the sector gear 12 mesh with the double-sided rack 9, causing the double-sided rack 9 to move parallel on the support plate 6. The sector gear 12 drives the double-sided rack 9 to move back and forth left and right through the up and down cooperation. Then, the fertilizer is put into the interior through the top of the shell 1. The double-sided rack 9 drives the frame 4 to move back and forth left and right within the limit of the guide rail 3 through the connecting rod 10. Then, the fertilizer is screened through the screen 5, which achieves the effect of reducing the occupied area.
[0037] As the screen 5 moves back and forth in the left and right directions, the screen 5 comes into contact with the bristles 16. The bristles 16 are limited within the support rod 14 by the limiting plate 15, and supported by the tension of the spring 18, so that the bristles 16 can always stick to the bottom of the screen 5. Thus, as the screen 5 moves back and forth, it contacts the bristles 16 to perform self-cleaning, achieving the effect of self-cleaning the screen 5 while screening.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
