Description

Technical Field

[0001] This utility model relates to the field of building aggregate screening technology, specifically a multi-stage screening device for building aggregates. Background Technology

[0002] Building aggregates are granular loose materials that act as a skeleton or filler in concrete. As the main raw material in concrete, aggregates play a skeleton and supporting role in buildings. There are two types of aggregates: fine aggregates and coarse aggregates. Due to the different sizes of aggregates, in order to ensure the quality of concrete, aggregates need to be screened before use.

[0003] Most existing building aggregate screening methods only use a single filter plate, which has limited filtration efficiency. Some multi-stage screening devices are not convenient for collecting and cleaning the screened aggregate. In addition, feeding too much material at once during screening will affect the screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage screening device for building aggregates to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage screening device for building aggregates, comprising a housing, the bottom of which is fixedly connected to a base, a screen plate inside the housing, the screen plate being movably hinged to one end of a connecting plate, the connecting plate being fixedly connected to a fixed plate, a dual-axis motor fixedly mounted on the upper surface of the fixed plate, the output end of the dual-axis motor being fixedly connected to a rotating shaft, an ear plate fixedly connected to the upper surface of the fixed plate, one end of the rotating shaft being fixedly connected to a rotating plate, the side of the rotating plate being movably hinged to one end of a linkage plate, the other end of the linkage plate being hinged to the side of a second screen plate, the second screen plate being hinged to one end of a hinged plate, the side of the housing being fixedly connected to a discharge port, a collection hopper inside the housing, a feeding hopper fixedly connected to the upper surface of the housing, a feeding motor fixedly mounted on the upper surface of the housing, the output end of the feeding motor being fixedly connected to an adjusting plate, and a feeding hole being provided on the adjusting plate.

[0006] Preferably, a rectangular through hole is provided on the side of the housing, the outer side of the discharge port is fixedly connected to the inner wall of the rectangular through hole, a slot is provided inside the housing, and the housing is movably inserted into the outer side of the collection hopper through the slot.

[0007] Preferably, one end of both the first screen plate and the second screen plate are inclined downwards, the first screen plate is inclined toward the discharge port side, and the two ends of the hinge plate are respectively movably hinged to the first screen plate and the second screen plate.

[0008] Preferably, the two ends of the connecting plate are movably hinged to the inner wall of the housing and the first sieve plate, respectively, and the first sieve plate and the second sieve plate are arranged in parallel.

[0009] Preferably, the rotating plate is an eccentric block, the center of gravity of the rotating plate is located outside the rotating shaft, the side of the rotating plate is hinged to one end of the linkage plate through a hinge shaft, and the other end of the linkage plate extends to the other side of the screen plate and is hinged to the screen plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses a dual-axis motor to drive the rotating shaft to rotate the rotating plate. Since the rotating plate is an eccentric block, it drives the first screen plate to vibrate. The rotation of the rotating plate drives the second screen plate to vibrate through the linkage plate. Multi-stage screening is achieved through the first and second screen plates. The inclined setting allows the screened aggregate to be discharged from the outlet for collection. Vibration improves the filtration efficiency of the first and second screen plates. The synchronous vibration of the first and second screen plates can be achieved with a single drive source, reducing equipment costs and maintenance difficulty.

[0012] 2. This utility model also uses a feeding motor to rotate the adjusting plate. When the adjusting plate rotates and the discharge hole connects with the bottom of the feed hopper, the aggregate can be fed in, avoiding the situation where a large amount of aggregate is fed in at one time, which affects the filtration efficiency and enhances the actual use effect.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a multi-stage screening device for building aggregates, including a housing 1. A transparent observation window is provided on the side of the housing 1, allowing the screening effect inside the housing 1 to be observed through the window. A rectangular through-hole is provided on the side of the housing 1, and the outer side of the discharge port 13 is welded and fixed to the inner wall of the rectangular through-hole. The discharge port 13 is adapted to the positions of screen plate 3 and screen plate 11. A slot is provided inside the housing 1, and the housing 1 is movably inserted into the outer side of the collection hopper 14 through the slot. A handle is welded and fixed to the side of the collection hopper 14, allowing the collection hopper 14 to be directly pulled out from inside the housing 1. The collection hopper 14 collects the aggregate filtered by screen plate 3 and screen plate 11. The bottom of the housing 1 is welded and fixed to a base 2, and the bottom of the base 2 is provided with anti-slip support feet.

[0020] A sieve plate 3 is installed inside the housing 1. The sieve plate 3 is hinged to one end of a connecting plate 4. Both ends of the connecting plate 4 are hinged to the inner wall of the housing 1 and the sieve plate 3, respectively. One end of the connecting plate 4 is welded to a fixed plate 5. The upper surface of the fixed plate 5 is bolted to a dual-shaft motor 6. The output end of the dual-shaft motor 6 is welded to a rotating shaft 7. The upper surface of the fixed plate 5 is welded to an ear plate 8. The outer side of the rotating shaft 7 is rotatably connected to the ear plate 8 via a bearing. One end of the rotating shaft 7 is welded to a rotating plate 9. The rotating plate 9 is an eccentric block, and its center of gravity is located outside the rotating shaft 7. The dual-shaft motor 6 causes the rotating shaft 7 to drive the rotating plates 9 on both sides to rotate. The eccentric rotation of the rotating plate 9's center of gravity drives the sieve plate 3 and the dual-shaft motor 6 to vibrate. The sieve plate 3 achieves the vibration effect with the cooperation of the connecting plate 4.

[0021] The rotating plate 9 is hinged to one end of the linkage plate 10, and the other end of the linkage plate 10 is hinged to the side of the second screen plate 11. The second screen plate 11 is hinged to one end of the hinge plate 12, and both ends of the hinge plate 12 are hinged to the first screen plate 3 and the second screen plate 11, respectively. The first screen plate 3 and the second screen plate 11 are arranged parallel to each other, with one end of each screen plate 3 and the second screen plate 11 inclined downwards. The first screen plate 3 is inclined towards the discharge port 13. The rotating plate 9 is hinged to one end of the linkage plate 10 via a hinge shaft, and the other end of the linkage plate 10 extends to the other side of the first screen plate 3 and is hinged to the second screen plate 11. The rotation of the linkage plate 10 by the rotating plate 9 causes the second screen plate 11 to vibrate, and the movement of the second screen plate 11 by the linkage plate 10 is achieved. The vibration of the second screen plate 11 is coordinated with the vibration of the hinge plate 12 to avoid interference.

[0022] The side of the shell 1 is welded and fixed to the discharge port 13. A collection hopper 14 is provided inside the shell 1. The upper surface of the shell 1 is welded and fixed to the feed hopper 15. A feeding motor 16 is fixedly installed on the upper surface of the shell 1. The output end of the feeding motor 16 is welded and fixed to the adjusting plate 17. Several feeding holes 18 are opened on the adjusting plate 17. As the adjusting plate 17 rotates, it drives the feeding holes 18 to move intermittently to the bottom of the feed hopper 15 for feeding.

[0023] Working principle: During use, aggregate is fed into the feed hopper 15. The feeding motor 16 causes the adjusting plate 17 to rotate until the feed hole 18 is connected to the bottom of the feed hopper 15. The rotation of the adjusting plate 17 causes the aggregate in the feed hopper 15 to be discharged intermittently. The fixed plate 5 causes the rotating shaft 7 and the rotating plate 9 to rotate. Since the center of gravity of the rotating plate 9 is outside the rotating shaft 7, the rotation of the rotating plate 9 will cause the screen plate 3 to vibrate. At the same time, the rotation of the rotating plate 9 causes the linkage plate 10 to drive the screen plate 11 to vibrate. The connecting plate 4 and the hinge plate 12 provide operability for the vibration of the screen plate 3 and the screen plate 11. The dual-shaft motor 6 can drive the vibration of the screen plate 3 and the screen plate 11. The multi-stage screening of aggregate is achieved through the screen plate 3 and the screen plate 11. Then, the aggregate screened at each stage is collected and discharged through the discharge port 13. The aggregate can also be collected through the bottom collection hopper 14 to enhance the actual use effect.
