Description

Technical Field

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

[0002] In the construction industry, the quality of building aggregates plays a crucial role in the quality of construction projects. Building aggregates often need to be screened and graded before use to meet the different particle size requirements of various construction stages. Traditional building aggregate screening devices are typically complex in structure and cumbersome to operate. For example, some multi-stage screening devices use a fixed screen structure, which allows aggregates of different sizes to easily accumulate on the screen during screening, resulting in low screening efficiency and making it difficult to clean and maintain the screen. Furthermore, existing devices rely heavily on vibration to push and transfer aggregates, which is ineffective for larger particles and fails to precisely control the aggregate movement path, thus affecting the screening effect. Utility Model Content

[0003] This utility model provides a multi-stage screening device for building aggregates, which solves the problems of poor screening effect of existing screens on stockpiled aggregates and inconvenient screen replacement.

[0004] This utility model provides the following technical solution: It includes an outer casing, the inner wall of which has several slide tracks. A fixed frame is slidably connected to the inner wall of each slide track. A filter screen is installed on the inner wall of each fixed frame. A slide frame is provided on the outer casing, with a clearance channel at the top. A mounting bracket matching the clearance channel is slidably connected to the inner wall of the slide frame. Slider blocks are fixedly connected to both ends of the slide frame. A limiting groove matching the slider is provided on the outer casing. The sliders are connected by a connecting frame.

[0017] Please see Figures 1-4The present invention provides the following technical solution: it includes an outer casing 1, the inner wall of the outer casing 1 is provided with a plurality of slide tracks 2, the inner wall of the slide tracks 2 is slidably connected with a fixing frame 21, the inner wall of each fixing frame 21 is equipped with a filter screen 22, the outer casing 1 is provided with a slide 3, the top of the slide 3 is provided with a clearance channel 331, the inner wall of the slide 3 is slidably connected with a mounting frame 33 that matches the clearance channel 331, the two ends of the slide 3 are fixedly connected with sliders 32, the outer casing 1 is provided with a limiting groove 31 that matches the sliders 32, the sliders 32 are connected to each other by a connecting frame 34, the inner wall of the connecting frame 34 is slidably connected with an adjusting block 35, the two sides of the outer casing 1 are provided with mating plates 36, the mating plates 36 are fixedly connected with adjusting rods 361, one of the adjusting rods 361 is threadedly connected to the adjusting block 35.

[0018] In this implementation scheme: the outer casing 1 serves as the carrier of the supporting device. Several slide rails 2 formed on the inner wall of the outer casing 1 allow the fixing frame 21 to slide along one end of the outer casing 1. After sliding along the inner wall of the outer casing 1, it is supported by the inner wall of the outer casing 1. The slide rails 2 have a certain inclination angle, ensuring that the fixing frame 21 is stably supported by the inner wall of the outer casing 1 while allowing the building aggregate on the fixing frame 21 to roll downwards easily. The inner wall of the fixing frame 21 is sealed by a filter screen 22 fixedly connected to it. The building aggregate is placed onto the uppermost filter screen 22, and at this time, it can slide along the inner wall of the outer casing 1 via the slide rails 3. The slide 3 can be slidably supported on the inner wall of the limiting groove 31 by the sliders 32 fixedly connected at both ends, so that the slide 3 can slide stably in the inner wall of the outer box 1. At the same time, several slides 3 are connected vertically to each other and can slide on both sides of the outer box 1 through the connecting frame 34. At this time, the docking plate 36 fixedly connected to both sides of the outer box 1 can install the adjusting rod 361. The adjusting rod 361 can be connected to the adjusting block 35 slidably connected to the inner wall of the connecting frame 34, so that one of the adjusting rods 361 is threadedly connected to the adjusting block 35. A motor 37 fixedly connected to the docking plate 36 is connected to one end of the adjusting rod 361, so that the motor 37 can adjust one of the rods 361. The adjusting rod 361 is driven to adjust the position of the adjusting block 35. Simultaneously, the adjusting block 35 slides against the inner wall of the connecting frame 34. When the adjusting block 35 is maintained at the same height as the docking plate 36 under the connection of the adjusting rod 361, and a certain height difference is created by the adjustment of the connecting frame 34, the sliding of the adjusting block 35 ensures that it is supported and limited within the inner wall of the connecting frame 34. This allows the connecting frame 34 to be pushed to a higher position without being restricted, thus allowing the several carriages 3 to adjust their position on the filter screen 22. This ensures that materials placed on one side of the carriage 3 can be pushed by the carriage 3 without being restricted. The material is displaced on the filter screen 22, allowing it to roll downwards on the inclined surface of the filter screen 22. Smaller particles can pass through the preset apertures on the filter screen 22 and fall onto the next layer of filter screen 22, thus enabling the building aggregate to be graded and screened. At the same time, the mounting bracket 33 installed on the inner wall of the slider 32 is used to seal the inner wall of the slider 32. It can be separated by the clearance channel 331 opened at the top, allowing the slider 3 to allow the aggregate to pass through its inner wall and roll downwards on the filter screen 22. This allows aggregates of different sizes to be used separately, avoiding accumulation in different layers where they are difficult to move. For larger aggregates, vibration and other methods are less effective.

[0019] Several discharge pipes 27 are installed at one end of the outer casing 1. The discharge pipes 27 are connected to the outer casing 1. A partition 28 is slidably connected to the discharge pipes 27. After the partition 28 slides upward, the several discharge pipes 27 installed at one end of the outer casing 1 can allow the aggregate on the filter screen 22 to slide downward, so that it can be collected and processed after passing through the discharge pipes 27.

[0020] A limiting block 311 is fixedly connected at the connection between the limiting groove 31 and the slider 32, and the slider 32 is slidably connected to the limiting block 311. The limiting block 311 fixedly connected at the connection between the limiting groove 31 and the slider 32 can connect and limit the outer wall of the slider 32, so that the slider 32 can be locked and supported on the inner wall of the limiting groove 31, ensuring its stable position, while allowing it to slide on the inner wall of the limiting groove 31 for position adjustment.

[0021] One of the docking plates 36 has a motor 37 installed on one side. The driving end of the motor 37 is connected to one end of one of the adjusting rods 361. The other adjusting rod 361 passes through another adjusting block 35. The motor 37 installed on one side of the docking plate 36 can drive the adjusting rod 361. The driving end of the motor 37 can drive the adjusting rod 361 to rotate, so that the adjusting rod 361 can adjust the position of the adjusting block 35 and push the motor 37. At the same time, the other adjusting rod 361 is slidably connected to its corresponding adjusting block 35, ensuring that the connecting frame 34 can be connected to both ends of the connecting frame 34 and make it move steadily.

[0022] A positioning plate 23 is fixedly connected to one end of the fixing frame 21, and an insertion rod 25 is slidably connected to one side of the outer casing 1. The insertion rod 25 passes through the positioning plate 23. The positioning plate 23, which is fixedly connected to one end of the fixing frame 21, is located on the outer side of one end of the outer casing 1, so that the insertion rod 25 can be connected and limited on the positioning plate 23, thereby positioning the position of the positioning plate 23. This ensures that the positioning plate 23 is stable after the fixing frame 21 is installed, and at the same time, it allows the insertion rod 25 to slide out, so that the positioning plate 23 can pull the fixing frame 21 out.

[0023] An installation rod 24 is fixedly connected to one side of the outer casing 1. A limit rod 26 is fixedly connected to the installation rod 24. The limit rod 26 is slidably connected to the insertion rod 25. The installation rod 24 can install the limit rod 26, so that the insertion rod 25 is slidably limited on the limit rod 26.

[0024] The working principle and usage process of this utility model are as follows: The fixing frame 21 is slid into the inner wall of the outer casing 1 from one end, and is stably supported by the inclined angle of the slide rail 2. The filter screen 22 is installed in the fixing frame 21 to seal the inner wall of the slide rail 2. The mounting frame 33 is installed on the inner wall of the slider 32 and made separable. The two ends of the slider 32 are fixed on the slide frame 3 and can slide in the limiting groove 31. Multiple slide frames 3 are connected by the connecting frame 34. The adjusting block 35 slides in the connecting frame 34. The docking plate 36 is installed on both sides of the outer casing 1 and connected by the adjusting rod 361. One of the adjusting rods 361 is threadedly connected to the adjusting block 35. The motor 37 is installed on one side of the docking plate 36 and the driving end is connected to the adjusting rod 361. At the same time, the insertion rod 25 passes through and is limited on the positioning plate 23 and the limiting rod 26. Positioning plate 23 is fixed to one end of slide 2, mounting rod 24 and limiting rod 26 are fixed to one side of outer box 1, discharge pipe 27 is installed at one end of outer box 1 and connected to outer box 1, partition plate 28 can slide on discharge pipe 27, place the aggregate to be screened on the uppermost filter screen 22, start motor 37, its drive end drives adjustment rod 361 to rotate. Because adjustment rod 361 is threadedly connected to adjustment block 35, adjustment block 35 slides in connecting frame 34 to push connecting frame 34, driving multiple slides 3 to adjust position on inner wall of outer box 1. Material is displaced on filter screen 22 under the push of slides 3, and rolls down along the inclined surface of slide 2. Small particles fall to lower filter screen 22 through preset aperture of filter screen 22, realizing graded screening, and large particles can also move and be screened continuously.
