Description
Technical Field
[0001] This utility model relates to the field of vibrating screen technology, specifically a vibrating screen fixing device. Background Technology
[0002] With its unique design, the vibrating screen cleverly transforms the rotational motion of the motor into three-dimensional motion—horizontal, vertical, and inclined—giving the material a dynamic trajectory of an outward-expanding involute. This powerful screening tool boasts high screening accuracy and outstanding efficiency, accurately screening granular, powdery, or viscous materials, easily meeting diverse production needs.
[0003] Vibrating screens use motors or vibrators to drive the screen surface to generate high-frequency vibrations, causing the material to jump and stratify on the screen surface. Particles smaller than the screen holes fall through the screen surface to complete the screening, while particles larger than the screen holes are discharged along the screen surface, thus achieving the separation of materials of different particle sizes.
[0004] Since the vibrating screen screens materials by vibrating, it continuously transmits vibrations to the screen base. These vibrations cause the base to move on the ground, resulting in overall displacement.
[0005] Therefore, a vibrating screen fixing device is proposed to address the above problems. Utility Model Content

[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a vibrating screen fixing device includes a base plate 1. A plurality of slide rods 11 are fixedly connected to the top of the base plate 1. A support plate 13 is slidably connected to the end of each slide rod 11. A plurality of compression springs 12 are fixedly connected to the bottom of the support plate 13. The compression springs 12 are sleeved on the surface of the slide rods 11. An adjusting component 104 is provided at the bottom of each slide rod 11. The adjusting component 104 and the compression springs 12 are in contact. A pair of air springs 14 are fixedly connected between the support plate 13 and the base plate 1. An air pump 15 is provided on the side wall of the base plate 1. The air pump 15 and the air springs 14 are connected via air pipes 16. A plurality of... A first locking block 17; a pair of insert blocks 18 are fixedly connected to the side wall of the first locking block 17; a second locking block 19 is slidably connected to the top of the support plate 13; the second locking block 19 and the first locking block 17 are correspondingly arranged; a pair of slots 101 are opened on the side wall of the second locking block 19; the insert blocks 18 and the slots 101 are correspondingly arranged and slidably engaged; a pair of pin slots 102 are opened in the middle of the insert blocks 18 and the second locking block 19; the insert blocks 18 and the slots 101 are connected by pins; a vibrating screen body 103 is arranged between the first locking block 17 and the second locking block 19; during operation, the vibrating screen body 103 is first placed on the surface of the support plate 13 and then the support legs are placed on the first locking block 17. Between the first locking block 17 and the second locking block 19, the support plate 13 will descend due to the weight of the vibrating screen body 103. During descent, it will compress the compression spring 12. After placement, the first locking block 17 and the second locking block 19 are merged, so that the second locking block 19 is inserted into the slot 101. Then, the pin is inserted into the pin slot 102 to fix the first locking block 17 and the second locking block 19. Subsequently, when the vibrating screen body 103 vibrates during operation, the space between the first locking block 17 and the second locking block 19 can limit the movement range of the vibrating screen body 103. Then, when the vibration is transmitted, the air pump 15 can be used to activate the air spring. 14 is started to absorb and eliminate the vibration generated by the vibrating screen body 103. At the same time, the compression spring 12 can be adjusted by the adjustment component 104 to absorb the transmitted vibration, so that it works with the air spring 14 to reduce the shaking caused by vibration. By adding the first locking block 17 and the second locking block 19, the range of shaking of the vibrating screen body 103 can be limited. Then, the transmitted vibration is absorbed by the air spring 14 and the compression spring 12. When in use, the vibration is quickly eliminated by the absorption and diffusion of the air spring 14 and the compression spring 12, thereby reducing the shaking caused by vibration and making it more stable after placement and reducing positional deviation.
[0026] like Figures 1 to 4As shown, multiple damping spring dampers 2 are fixedly connected to the middle of the second block 19 and the first block 17; a buffer plate 21 is fixedly connected to the end of the damping spring damper 2; during operation, when the vibrating screen body 103 shakes, it will contact the buffer plate 21. When the buffer plate 21 is hit by the vibrating screen body 103, it can transmit the force received to the damping spring damper 2. When the damping spring damper 2 receives the impact force, it will gradually eliminate the impact force through its own damping characteristics. Thus, through multiple contacts, the vibration of the vibrating screen body 103 is gradually eliminated multiple times. By adding damping spring dampers 2, the force can be absorbed when the vibrating screen body 103 vibrates, and then gradually eliminated through the damping spring dampers 2 on both sides, thereby reducing the downward transmission and increasing the path for vibration elimination. Thus, the attached air spring 14 eliminates the vibration of the vibrating screen body 103.
[0027] like Figure 3 As shown, a plurality of ball bearings 3 are rotatably connected to the middle of the base plate 1; the ball bearings 3 are located between the first locking block 17 and the second locking block 19; during operation, when the vibrating screen body 103 shakes due to vibration, it will continuously contact the ball bearings 3, and the ball bearings 3 will roll together when in contact. When rolling, it will reduce the friction between the vibrating screen body 103 and the support plate 13, thereby accelerating the contact with the buffer plate 21, and thus damping the vibration when in contact; by increasing the number of ball bearings 3, the friction between the vibrating screen body 103 and the support plate 13 can be reduced, so that it can contact the buffer plate 21 faster when shaking, and gradually eliminate the received vibration when damping the vibration.
[0028] like Figure 4 As shown, a buffer pad 4 is fixedly connected to the side wall of the buffer plate 21; the buffer pad 4 and the buffer plate 21 are arranged correspondingly; during operation, when the vibrating screen body 103 shakes during operation, it will continuously move back and forth towards the buffer plate 21. When it approaches the buffer plate 21, the buffer pad 4 will first approach the vibrating screen body 103. At this time, when in contact, the buffer pad 4 will quickly disperse the absorbed buffer through its own flexibility, spreading it to the surroundings, thereby reducing the vibration transmitted to the buffer plate 21; by adding the buffer pad 4, the received vibration can be weakened by the flexibility of the buffer pad 4 before the vibrating screen body 103 and the buffer plate 21 come into contact, thereby preliminarily treating it before contact with the buffer plate 21.
[0029] like Figure 2 As shown, multiple anti-slip pads 5 are fixed to the bottom of the base plate 1; the anti-slip pads 5 are inclined; during operation, after the base plate 1 is placed on the ground, the anti-slip pads 5 will be in close contact with the ground. When in close contact, the friction between the base plate 1 and the ground will be increased, thus making the vibrating screen body 103 more stable when damping vibration; by adding anti-slip pads 5, the friction between the base plate 1 and the ground can be increased when it is in use, making it more stable during operation and reducing positional deviation.
[0030] like Figures 1 to 5 As shown, the adjustment assembly 104 includes multiple nuts 6; the nuts 6 and the slide rod 11 are threadedly connected; during operation, the nuts 6 can be rotated to move on the slide rod 11 during long-term operation of the vibrating screen body 103, and the movement will compress the compression spring 12. When compressed, the compression spring 12 will increase its rigidity, thus absorbing the transmitted vibration more quickly; by using the nuts 6, the degree of compression of the compression spring 12 can be quickly adjusted to absorb vibration when encountering different vibration intensities, thereby increasing the flexibility of the compression spring 12.
[0031] Working principle: First, the vibrating screen body 103 is placed on the surface of the support plate 13, and then the support legs are placed between the first locking block 17 and the second locking block 19. At this time, the support plate 13 will descend due to the weight of the vibrating screen body 103. During the descent, it will compress the compression spring 12. After placement, the first locking block 17 and the second locking block 19 are merged, so that the second locking block 19 is inserted into the slot 101. Then, the pin is inserted into the pin slot 102 to fix the first locking block 17 and the second locking block 19. Subsequently, when the vibrating screen body 103 vibrates during operation, the vibration can be controlled by the first locking block 17 and the second locking block 19. The space between the blocks 19 restricts the movement range of the vibrating screen body 103. Then, when vibration is transmitted, the air pump 15 can activate the air spring 14 to absorb and eliminate the vibration generated by the vibrating screen body 103. Simultaneously, the adjustment component 104 can be used to adjust the compression spring 12, which also absorbs the transmitted vibration, thus working together with the air spring 14 to reduce the swaying caused by vibration. When the vibrating screen body 103 shakes during operation, it will contact the buffer plate 21. When the buffer plate 21 is impacted by the vibrating screen body 103, the force received can be transmitted to the damping spring shock absorber 2. When the damping spring... When the vibrator 2 receives an impact force, it gradually eliminates the impact force through its own damping characteristics. This is achieved through repeated contact during the initial contact, gradually eliminating vibration in the vibrating screen body 103. When the vibrating screen body 103 sways due to vibration, it continuously contacts the ball bearings 3. During contact, the ball bearings 3 roll along with the vibrating screen body 103, reducing friction between the vibrating screen body 103 and the support plate 13, thus accelerating contact with the buffer plate 21 and providing shock absorption. As the vibrating screen body 103 sways during operation, it continuously moves closer to the buffer plate 21. When it approaches the buffer plate 21, the buffer pad 4 first contacts the vibrating screen body 103. When the screen approaches, the buffer pad 4 will quickly disperse the absorbed vibration through its flexibility, spreading it to the surrounding area and thus reducing the vibration transmitted to the buffer plate 21. After the base plate 1 is placed on the ground, the anti-slip pad 5 will be in close contact with the ground. When in close contact, the friction between the base plate 1 and the ground will be increased, thus making the screen body 103 more stable when damping vibration. During long-term operation of the screen body 103, the nut 6 can be rotated to move on the slide rod 11. When moving, the compression spring 12 will be compressed. When compressed, the compression spring 12 will increase its rigidity, thus absorbing the transmitted vibration more quickly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
