Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, and more particularly to a vibrating screen that is convenient for feeding materials. Background Art

[0002] Vibrating screen, as one of the common screening equipment, is often used to screen powder. It can remove excess impurities in the powder and make the powder finer.

[0003] When an existing vibrating screen is used to screen powder, the powder is usually poured into the feed port, and then the vibrating screen is started to vibrate the screen on the vibrating screen. At the same time, the powder is guided to the screen of the vibrating screen through the feed port. At this time, the powder is affected by the vibration of the screen, causing the powder to fall down through the mesh holes on the screen and be separated from the impurities in the powder. At the same time, the impurities will be affected by the vibration, move along the surface of the filter, and be separated from each other through the discharge port and the vibrating screen, thereby achieving the effect of using a vibrating screen to screen the powder.

[0004] However, after the vibrating screen has finished screening the powder, a small amount of powder usually remains in the impurities separated from the vibrating screen. In order to save costs and improve the screening effect of the powder, the staff usually use tools such as shovels to put the impurities back into the feed port several times and perform secondary screening. However, when putting the impurities back into the feed port, the staff needs to use tools multiple times to completely put the impurities into the feed port. The process is too cumbersome and affects work efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a vibrating screen that is easy to feed, which solves the problem that when putting impurities back into the feed port, the staff needs to use tools multiple times to completely put the impurities into the feed port, and the process is too cumbersome, which affects work efficiency.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: a vibrating screen that is convenient for feeding, comprising a vibrating screen body with a feed port, a discharge port and a filter screen, and also comprising a plurality of storage frames placed at the discharge port, wherein the feed port of the vibrating screen body is fixedly connected to a feed pipe, an annular groove is provided in the feed pipe, one of the storage frames and the annular groove is detachably connected, a through groove is provided at the bottom of the storage frame, a baffle is rotatably connected to the through groove, the baffle and the through groove are connected by a clamping assembly, and when the storage frame and the feed pipe are installed to each other, the baffle and the through groove are no longer clamped.

[0008] By adopting the above-mentioned structural arrangement, when the vibrating screen is used to screen the powder, the impurities will fall outward through the discharge port on the vibrating screen body. At this time, the storage frame is placed at the discharge port to collect the impurities. When the impurities need to be screened for a second time, the storage frame is placed in the feed pipe and installed with the annular groove. At the same time, the restriction between the baffle and the through groove is cancelled by the clamping assembly, and the baffle and the through groove are separated from each other. At this time, the impurities in the storage frame will enter the feed pipe through the through groove, and the impurities will be transported to the vibrating screen body through the feed pipe, and the impurities will be screened for a second time, so as to achieve the effect of putting impurities into the vibrating screen body without the staff using tools, thereby reducing the staff's work intensity, facilitating the staff's operation, and improving work efficiency.

[0009] The utility model is further configured as follows: the clamping assembly includes a slide groove opened on the inner side of the material storage frame, a movable ring is slidably connected in the slide groove, a limiting plate is fixedly connected to the movable ring, the limiting plate and the slide groove are slidably connected, the side wall of the baffle is opened with a groove, a limiting block is slidably connected in the groove, the limiting block and the groove are connected by a spring 1, when the material storage frame and the feeding pipe are installed to each other, the spring 1 is in a natural state, and at this time the limiting block and the inner side of the movable ring contact each other, a driving member for driving the movable ring to move along the slide groove is provided on the annular groove, and one side of the limiting block is inclined.

[0010] When the baffle rotates until the limiting block and the inner side wall of the moving ring are aligned with each other, the spring loses its restriction and deforms and restores, driving the limiting block and the inner side wall of the moving ring to contact each other, thereby achieving the effect of clamping the baffle and the through groove together.

[0011] The utility model is further configured as follows: the driving member includes a fixed block fixedly connected to the annular groove, and when the material storage frame and the material feeding pipe are installed with each other, the fixed block is inserted into the sliding groove.

[0012] By adopting the above-mentioned driving member setting, when it is necessary to drive the movable ring to move along the slide groove, the material storage frame is installed in the annular groove, and the fixed block and the movable ring are driven to contact each other. At this time, pressure is applied to the material storage frame to drive the material storage frame to move downward, and at the same time, the movable ring is driven to move along the slide groove under the influence of the fixed block, and the fixed block is driven to be inserted into the slide groove, thereby achieving the effect of driving the movable ring to move.

[0013] The utility model is further configured as follows: a connecting block is fixedly connected to the inner side of the material storage frame, and the connecting block is in contact with the limiting plate and the movable ring respectively.

[0014] By adopting the arrangement of the connecting block, impurities can be prevented from entering the chute, making it easier for the movable ring to move in the chute.

[0015] The utility model is further configured such that: when the limiting block and the inner side wall of the movable ring are in contact with each other, the baffle and the connecting block are in contact with each other.

[0016] By adopting the above technical solution, the rotation range of the baffle can be limited, thereby improving the stability of the baffle during rotation. At the same time, the sealing effect between the baffle and the through groove can be improved, preventing impurities from falling out through the gap between the baffle and the through groove.

[0017] The utility model is further configured as follows: the limit plate and the slide groove are connected by spring 2; when spring 2 is in a natural state, the limit block and the inner wall of the movable ring contact each other; and the elastic potential energy of spring 2 is greater than the elastic potential energy of spring 1.

[0018] By adopting the arrangement of the above-mentioned spring 2, it is possible to facilitate the contact between the limiting block and the inner side wall of the movable ring, and at the same time, the stability of the movable ring in the sliding groove can be improved.

[0019] The utility model is further configured as follows: a plurality of limit blocks are rotatably connected to the top of the feeding pipe, and the limit blocks and the material storage frame are in contact with each other.

[0020] By adopting the setting of the above-mentioned limit block, it is possible to avoid the position of the storage frame from being offset when the storage frame and the annular groove are installed with each other, thereby improving the fixing effect between the storage frame and the annular groove.

[0021] To sum up, the utility model has the following beneficial effects: when it is necessary to perform secondary screening of impurities, the storage frame and the annular groove are installed with each other, and the restriction between the baffle and the through groove is removed by the clamping assembly.

[0029] A vibrating screen that is easy to feed, such as Figure 1-Figure 3As shown, it includes a vibrating screen body 1 with a feed port, a discharge port and a filter screen, and also includes several storage frames 4 placed at the discharge port. The feed port of the vibrating screen body 1 is fixedly connected to a feed pipe 2, and an annular groove 3 is provided in the feed pipe 2. One of the storage frames 4 and the annular groove 3 is detachably connected. A through groove 5 is provided at the bottom of the storage frame 4. A baffle 6 is rotatably connected to the through groove 5. The baffle 6 and the through groove 5 are connected by a clamping assembly. When the storage frame 4 and the feed pipe 2 are installed with each other, the baffle 6 and the through groove 5 are unclamped. When the vibrating screen is used to screen the powder, impurities will fall outward through the discharge port on the vibrating screen body 1. At this time, the storage frame 4 is placed at the discharge port and impurities are collected. When the impurities need to be screened for the second time, the storage frame 4 is placed in the feed pipe 2 and installed with the annular groove 3. At the same time, the restriction between the baffle 6 and the through groove 5 is cancelled by the clamping assembly, and the baffle 6 and the through groove 5 are separated from each other. At this time, the impurities in the storage frame 4 will enter the feed pipe 2 through the through groove 5, and the impurities will be transported to the vibrating screen body 1 through the feed pipe 2, and the impurities will be screened for the second time, so as to achieve the effect of putting impurities into the vibrating screen body 1 without the staff using tools, reducing the staff's operating steps and improving work efficiency.

[0030] like Figure 2 and Figure 3 As shown, the clamping assembly includes a slide groove 7 opened on the inner side of the material storage frame 4, a moving ring 8 is slidably connected in the slide groove 7, a limit plate 9 is fixedly connected to the moving ring 8, the limit plate 9 and the slide groove 7 are slidably connected, a groove 10 is opened on the side wall of the baffle 6, a limit block 11 is slidably connected in the groove 10, the limit block 11 and the groove 10 are connected by a spring 12, when the material storage frame 4 and the feeding pipe 2 are installed to each other, the spring 12 is in a natural state, and at this time the limit block 11 and the inner side of the moving ring 8 contact each other, a driving member for driving the moving ring 8 to move along the slide groove 7 is provided on the annular groove 3, and one side of the limit block 11 is inclined, and the driving member includes a fixed block 13 fixedly connected to the annular groove 3, and when the material storage frame 4 and the feeding pipe 2 are installed to each other, the fixed block 13 is inserted into the slide groove 7.

[0031] When the material storage frame 4 is placed in the annular groove 3, the fixed block 13 and the movable ring 8 are driven to contact each other. At this time, pressure is applied to the material storage frame 4 to drive the material storage frame 4 to move downward, and at the same time, the movable ring 8 is driven to move along the slide groove 7 under the influence of the fixed block 13, and the fixed block 13 is driven to be inserted into the slide groove 7. At the same time, the limiting block 11 is driven to move into the groove 10 through the inclined surface of the limiting block 11. At this time, the limiting block 11 and the movable ring 8 are separated from each other, and the baffle 6 and the through groove 5 are driven to separate from each other, thereby achieving the effect of canceling the engagement between the baffle 6 and the through groove 5, and the impurities in the material storage frame 4 completely enter the vibration groove 7. When the screen body 1 is inside, the material storage frame 4 is taken out from the annular groove 3. At this time, the movable ring 8 loses its restriction and returns to its original position, and then drives the baffle 6 to rotate, and drives the limiting block 11 and the movable ring 8 to contact each other. At this time, continue to apply pressure to the baffle 6, drive the limiting block 11 to enter the groove 10 again, and drive the spring 12 to deform and compress. When the baffle 6 is rotated to align the limiting block 11 and the inner side walls of the movable ring 8 with each other, the spring 12 loses its restriction and deforms and recovers, and drives the limiting block 11 and the inner side walls of the movable ring 8 to contact each other, thereby achieving the effect of clamping the baffle 6 and the through groove 5 with each other.

[0032] like Figure 2 and Figure 3 When the limit block 11 and the inner wall of the moving ring 8 are in contact with each other, the baffle 6 and the connecting block 14 are in contact with each other, which can limit the rotation range of the baffle 6 and improve the stability of the baffle 6 during rotation. At the same time, it can also improve the sealing effect between the baffle 6 and the through groove 5 to prevent impurities from falling outward through the gap between the baffle 6 and the through groove 5. The limit plate 9 and the slide groove 7 are connected by the spring 2 15. When the spring 2 15 is in the natural state, the limit block 11 and the inner wall of the moving ring 8 are in contact with each other. The elastic potential energy of the spring 2 15 is greater than the elastic potential energy of the spring 12, which can facilitate the contact between the limit block 11 and the inner wall of the moving ring 8 and improve the stability of the moving ring 8 in the slide groove 7.

[0033] like Figure 1 and Figure 2 As shown, several limit blocks 16 are rotatably connected to the top of the feed pipe 2. The limit blocks 16 and the storage frame 4 are in contact with each other, which can prevent the position of the storage frame 4 from being offset when the storage frame 4 and the annular groove 3 are installed with each other, thereby improving the fixing effect between the storage frame and the annular groove 3.

[0034] The working principle of the present invention is as follows: when the vibrating screen is used to screen the powder, the impurities will fall outward through the discharge port on the vibrating screen body 1. At this time, the storage frame 4 is placed at the discharge port and the impurities are collected. When the impurities need to be screened for the second time, the storage frame 4 is placed in the feeding pipe 2 and installed with the annular groove 3. At the same time, the movable ring 8 is driven to move along the slide groove 7 under the influence of the fixed block 13, and the fixed block 13 is driven to be inserted into the slide groove 7. At the same time, the limiting block 11 is driven to move into the groove 10 by the inclined surface of the limiting block 11. At this time, the limiting block 11 and the moving ring 8 are separated from each other, and the baffle 6 and the through groove 5 are driven to separate from each other. At this time, the impurities in the storage frame 4 will enter the feeding pipe 2 through the through groove 5, and the impurities are transported to the vibrating screen body 1 through the feeding pipe 2, and the impurities are screened for the second time, thereby achieving the effect of putting impurities into the vibrating screen body 1 without the staff using tools, reducing the staff's operating steps and improving work efficiency.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
