Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary vibrating screen technology, specifically a rotary vibrating screen with a buffer structure. Background Technology
[0002] A vibrating screen is a high-efficiency screening device mainly used for particle size classification, impurity filtration, and material purification of solid particles or powders. Its core function is to use three-dimensional vibration to create a spiral diffusion motion of the material on the screen surface, thereby achieving the separation of particles of different sizes.
[0003] Patent document CN210585815U discloses a feeding buffer device for a vibrating screen, including a first buffer tube. A first fixing ring is fixedly connected to the outer side of the top of the first buffer tube, and a second connecting ring is fixedly connected to the outer side of the bottom of the first buffer tube. The bottom of the second connecting ring is connected to the first connecting ring by screws. A second buffer tube is fixedly connected inside the first connecting ring, and a second fixing ring is fixedly connected to the outer side of the bottom of the second buffer tube. Both the first and second buffer tubes have arc-shaped connecting plates fixedly connected inside. The beneficial effects achieved are: compact structure, simple and convenient operation, and strong practicality. By setting buffer plates and return springs, the rapidly falling material is buffered, and the falling speed of the material is reduced. After the material is buffered twice by buffer plates in two directions, the material finally falls slowly into the screen, thus protecting the screen and increasing its service life. However, this patent still has the following problems in actual use:
[0004] This buffer device uses a first return spring and a second return spring at the bottom of the buffer plate to facilitate the buffering of materials entering the vibrating screen. However, during use, particles or powder tend to accumulate at the first and second return springs, which can easily cause contamination and make cleaning the buffer device inconvenient. Furthermore, the symmetrical arrangement of the buffer plates allows materials to pass through the two sets of buffer plates quickly, resulting in poor buffering effect and thus making the vibrating screen feeding buffer device less practical.
[0005] Therefore, a vibrating screen with a buffer structure is proposed to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a vibrating screen with a buffer structure to solve the problems mentioned in the background art. Currently, the buffer device uses a first and second return spring at the bottom of the buffer plate to facilitate buffering of materials entering the vibrating screen. However, during use, particles or powder easily accumulate at the first and second return springs, causing contamination and making cleaning the buffer device inconvenient. Furthermore, the symmetrical arrangement of the buffer plates allows materials to pass quickly through the two sets of buffer plates, resulting in poor buffering effect and thus poor practicality of the vibrating screen feeding buffer device.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotary vibrating screen with a buffer structure, comprising a rotary vibrating screen body;
[0008] The feed inlet is installed in the middle of the top of the vibrating screen body;
[0009] Also includes:
[0010] A feed pipe is provided above the main body of the vibrating screen. An inlet is opened in the middle of the top of the feed pipe. A rotating shaft is provided on one side of the inlet.

An arc rod is fixedly connected to one side of the sliding block.
[0012] The feed pipe has a material distribution plate at the lower end of its inner side, and a connection port is provided in the middle of the bottom end of the feed pipe.
[0013] Preferably, the cross-section of the connecting frame is triangular, and the connecting frame is symmetrically arranged on both sides of the support base. The support base is fixedly connected to the inner wall of the feed pipe through the connecting frame, which facilitates the positioning of the connecting frame.
[0014] Preferably, the supporting inclined surfaces are symmetrically arranged on both sides of the top of the support base, and the supporting inclined surfaces are parallel to the connecting frame, which facilitates the positioning of the supporting inclined surfaces.
[0015] Preferably, the arc-shaped groove is centrally symmetrically arranged on both sides of the upper end of the support base, and the ends of the two sets of arc-shaped rods away from the sliding block are respectively fixedly connected to one side of the bottom surface of buffer plate one and buffer plate two, which facilitates the positioning of the arc-shaped rods.
[0016] Preferably, the rotating shaft, buffer plate one, buffer plate two, support base, connecting frame, support inclined surface, arc groove, buffer spring, sliding block and arc rod are set in two sets to facilitate the limitation of buffer plate one and buffer plate two.
[0017] Preferably, the first buffer plate and the second buffer plate are symmetrically arranged on both sides of the rotating shaft, and the two sets of rotating shafts, the first buffer plate, the second buffer plate, the support base and the connecting frame are arranged perpendicularly to each other at the upper end and the middle of the inner wall of the feed pipe, which facilitates the positioning of the first buffer plate and the second buffer plate.
[0018] Preferably, the lower end of the feed pipe is funnel-shaped, the distribution plate is star-shaped, the distribution plate overlaps with the lower end of the feed pipe, and the bottom of the distribution plate is connected to the feed port through a connection port to facilitate the positioning of the distribution plate.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This vibrating screen with a buffer structure, through the arrangement of two sets of mutually perpendicular buffer plates one and two, makes the buffering effect of the vibrating screen stronger, thus facilitating the protection of the screen mesh. Furthermore, by setting a material distribution plate, it is easier to further buffer the material entering the vibrating screen and promote the uniform distribution of material on the inner side of the screen mesh. The specific details are as follows:
[0020] 1. This vibrating screen, by setting a feed pipe, buffer plate one, buffer plate two, support base, buffer spring and arc rod on one side of the feed inlet, facilitates the movement of buffer plate one and buffer plate two towards the buffer spring side by the gravity of the material as it falls, thereby achieving buffering before the material enters the vibrating screen. The arrangement of two sets of buffer plates one and two perpendicular to each other makes the vibrating screen more effective in buffering, thus facilitating the protection of the screen mesh. Therefore, this vibrating screen with buffer structure is more practical.
[0021] 2. By setting up a distribution plate, the material entering the vibrating screen can be further buffered, and the material can be more evenly distributed on the screen inside the vibrating screen, thus making the vibrating screen more practical. Attached Figure Description

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.
[0029] Please see Figures 1-5This utility model provides a technical solution: a vibrating screen with a buffer structure, including a vibrating screen body 1; a feed inlet 2 is installed in the middle of the top of the vibrating screen body 1; it also includes: a feed pipe 3 is provided above the vibrating screen body 1, an inlet 4 is opened in the middle of the top of the feed pipe 3, a rotating shaft 5 is provided on one side of the inlet 4, a buffer plate 6 is rotatably connected to one side of the rotating shaft 5, and a buffer plate 7 is rotatably connected to the other side of the rotating shaft 5; wherein, a support base 8 is provided below the rotating shaft 5, and the support base 8 is below... A connecting frame 9 is fixedly connected to one side of the support base 8. A supporting inclined surface 10 is provided on one side of the upper end of the support base 8. An arc-shaped groove 11 is provided on one side of the supporting inclined surface 10. A buffer spring 12 is fixedly connected to one side of the middle of the arc-shaped groove 11. A sliding block 13 is fixedly connected to one end of the buffer spring 12. An arc-shaped rod 14 is fixedly connected to one side of the sliding block 13. The cross-section of the connecting frame 9 is triangular. The connecting frame 9 is symmetrically arranged on both sides of the support base 8. The support base 8 is fixedly connected to the inner wall of the feed pipe 3 through the connecting frame 9. The supporting inclined surfaces 10 are symmetrically arranged on both sides of the top of the support base 8, and the supporting inclined surfaces 10 are parallel to the connecting frame 9; the arc-shaped grooves 11 are centrally symmetrically arranged on both sides of the upper end of the support base 8, and the ends of the two sets of arc-shaped rods 14 away from the sliding block 13 are respectively fixedly connected to one side of the bottom surface of the buffer plate 6 and the second buffer plate 7; the rotating shaft 5, the first buffer plate 6, the second buffer plate 7, the support base 8, the connecting frame 9, the supporting inclined surfaces 10, the arc-shaped grooves 11, the buffer springs 12, the sliding blocks 13, and the arc-shaped rods 14 are arranged in two sets. Buffer plates 6 and 7 are symmetrically arranged on both sides of the rotating shaft 5. The two sets of rotating shafts 5, buffer plates 6 and 7, support base 8 and connecting frame 9 are arranged perpendicularly to each other at the upper end and middle of the inner wall of the feed pipe 3. By setting two sets of mutually perpendicular rotating shafts 5, buffer plates 6 and 7, it is convenient to buffer the material that needs to enter the vibrating screen twice, so that only the material falling on the screen is buffered, thereby protecting the screen and extending the service life of the vibrating screen.
[0030] The feed pipe 3 has a material distribution plate 15 at its lower inner end and a connection port 16 at the middle of its bottom. The lower end of the feed pipe 3 is funnel-shaped, and the material distribution plate 15 is cross-shaped. The material distribution plate 15 overlaps with the lower end of the feed pipe 3, and the bottom of the material distribution plate 15 is connected to the feed inlet 2 through the connection port 16. By setting the material distribution plate 15, the material can fall evenly onto the screen, which facilitates the screening of the material. Therefore, the vibrating screen with a buffer structure is more practical.
[0031] Working principle: When using this vibrating screen with a buffer structure, firstly, the material is fed through the feed port 4 at the upper end of the feed pipe 3 so that the material falls onto the buffer plate 6 and the buffer plate 7. The buffer plate 6 and the buffer plate 7 rotate on the rotating shaft 5, thereby causing the buffer plate 6 and the buffer plate 7 to push the sliding block 13 to slide in the arc groove 11 on one side of the support seat 8 through the arc rod 14. At this time, the buffer spring 12 contracts, thereby buffering the buffer plate 6 and the buffer plate 7.
[0032] Secondly, the bottom surfaces of buffer plate 6 and buffer plate 7 overlap with the support slope 10, allowing the material to pass through the connecting frame 9, and then the material falls onto the next layer of buffer plate 6 and buffer plate 7.
[0033] Finally, the material passes through the distribution plate 15 at the lower end of the feed pipe 3 and falls onto the screen inside the vibrating screen body 1 through the feed port 2 via the connection port 16.
