Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a concrete raw material sorting device. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. It is made by mixing cement as the cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and is widely used in civil engineering. The density and strength of concrete are affected by the aggregate particle size. Excessively large aggregate particle size leads to increased internal porosity, reducing the strength and durability of the concrete. Conversely, excessively small particle size may result in poor flowability. Therefore, when preparing concrete from raw materials, it is necessary to sort the concrete aggregates. However, during screening, aggregates can become stuck in the sieve openings, causing clogging and reducing sorting efficiency. To address this, this application proposes a concrete raw material sorting device. Utility Model Content

Detailed Implementation

[0020] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0021] Example

[0022] See Figures 1 to 4 This utility model provides a concrete raw material sorting device, including a sorting screen 1, a guide plate 6, a hopper 7, a vibrating motor 10, a vibrating frame 11, a support 16, an adjusting mechanism 17, and a tilting mechanism 20. The vibrating frame 11 is connected to the support 16 and supports the vibrating frame 11. The vibrating motor 10, the adjusting mechanism 17, and the tilting mechanism 20 are respectively installed on the vibrating frame 11. The vibrating motor 10 drives the vibrating frame 11 to vibrate. The output end of the tilting mechanism 20 is connected to the sorting screen 1 through a connecting shaft 23. The connecting shaft 23 is rotatably connected to the vibrating frame 11. When the sorting screen 1 is blocked after working for a period of time, the tilting mechanism 20 is driven to drive the sorting screen 1. Rotating the screen changes the upward-facing surface of the sorting screen 1, causing the vibrating motor 10 to vibrate and dislodge concrete material stuck in the screen holes of the sorting screen 1. After clearing the concrete material blocking the screen holes of the sorting screen 1, concrete material can be fed into the sorting screen 1 for further sorting. Supports 24 are slidably connected to both sides of the vibrating frame 11. The output end of the adjusting mechanism 17 is connected to the two side supports 24 to drive the two side supports 24 to slide on the vibrating frame 11. The supports 24 are used to support the sorting screen 1 for sorting concrete. When the raw material is being processed, the bracket 24 supports the sorting screen 1. When it is necessary to clean the concrete raw material that is stuck in the screen hole of the sorting screen 1, the adjusting mechanism 17 adjusts the brackets 24 on both sides to slide in opposite directions, and the brackets 24 separate from the sorting screen 1, so that the sorting screen 1 can rotate. The hopper 7 and the guide plate 6 are respectively fixed on the bracket 16. The output port of the hopper 7 is located above the input end of the sorting screen 1, and concrete raw material is fed into the input end of the sorting screen 1. The guide plate 6 is located below the sorting screen 1, and guides and collects the sorted concrete raw material.

[0023] See Figure 2 and Figure 4 The bracket 24 includes a support plate 25, a connecting block 26 and a plurality of sliding rods 27. One end of the plurality of sliding rods 27 is slidably connected to the vibration frame 11, and the ends of the plurality of sliding rods 27 are connected to the support plate 25. The connecting block 26 is fixed to the support plate 25, and the sliding rods 27 can drive the support plate 25 to slide on the vibration frame 11.

[0024] The adjustment mechanism 17 includes a dual-axis motor 18 and two screws 19. The dual-axis motor 18 is mounted on the vibration frame 11. The two output shafts of the dual-axis motor 18 are respectively connected to the corresponding screws 19. The screws 19 are threadedly connected to the connecting block 26.

[0025] The dual-shaft motor 18 drives two screws 19 to rotate. The screws 19 are threadedly connected to the connecting block 26, the connecting block 26 is connected to the support plate 25, and the support plate 25 is connected to the slide rod 27. Thus, the slide rod 27 drives the support plate 25 to move, adjusting the distance between the support plate 25 and the sorting screen 1. When close, it can support the sorting screen 1; when far away, it facilitates the flipping of the sorting screen 1.

[0026] Two bearing seats 28 are fixed on the vibrating frame 11. The connecting shaft 23 is rotatably connected to the two bearing seats 28 to support the sorting screen 1 and facilitate the rotation of the connecting shaft 23.

[0027] The flipping mechanism 20 includes a motor 21 and a drive shaft 22. The motor 21 is mounted on the vibrating frame 11. The output shaft of the motor 21 is connected to the drive shaft 22. The drive shaft 22 is connected to the connecting shaft 23. The motor 21 drives the drive shaft 22 to rotate. The drive shaft 22 drives the sorting screen 1 to rotate through the connecting shaft 23.

[0028] The sorting screen 1 includes a first sorting screen 2 and a second sorting screen 3. The first sorting screen 2 and the second sorting screen 3 are respectively connected to both sides of the connecting shaft 23. The sides of the first sorting screen 2 and the second sorting screen 3 are respectively connected to support plates 4. The support plates 4 cooperate with the bracket 24. The upper and lower end faces of the first sorting screen 2 and the second sorting screen 3 are respectively connected to baffles 5. The baffles 5 can effectively prevent concrete raw materials from splashing to the sides, so that when the sorting screen 1 flips to continue sorting, it can still block the concrete raw materials. The hopper 7 is provided with a first discharge port 8 and a second discharge port 9. The first discharge port 8 is located above the input end of the first sorting screen 2, and the second discharge port 9 is located above the input end of the second sorting screen 3, so that concrete raw materials can be input into the corresponding first sorting screen 2 and second sorting screen 3 respectively.

[0029] The vibration frame 11 includes a vibration plate 12, a first support 13, a second support 14, and a plurality of vibration springs 15. The two ends of the plurality of vibration springs 15 are respectively connected to the vibration plate 12 and the bracket 16. The first support 13 and the second support 14 are respectively fixed on the vibration plate 12. The flipping mechanism 20 is installed on the first support 13, and the adjusting mechanism 17 is installed on the second support 14, which serves to support the flipping mechanism 20 and the adjusting mechanism 17.

[0030] In operation, concrete raw materials are fed into the input end of the first sorting screen 2 through the first discharge port 8, and into the input end of the second sorting screen 3 through the second discharge port 9. The vibrating motor 10 is started, causing the vibrating frame 11 to vibrate, thereby screening the concrete raw materials on the first sorting screen 2 and the second sorting screen 3. The screened concrete raw materials fall into the guide plate 6 and are collected. The tail material is output through the output ends of the first sorting screen 2 and the second sorting screen 3. When the screen openings of the first sorting screen 2 and the second sorting screen 3 are filled with concrete... When raw materials become stuck, the feeding of concrete raw materials into the first sorting screen 2 and the second sorting screen 3 is stopped. After the concrete raw materials on the first sorting screen 2 and the second sorting screen 3 are sorted, the dual-shaft motor 18 drives the screw 19 to rotate. The screw 19 is threadedly connected to the connecting block 26, and the slide rod 27 is slidably connected to the vibrating frame 11, causing the support plate 25 to move away from the sorting screen 1. The support plate 25 separates from the sorting screen 1, and the motor 21 drives the connecting shaft 23 to rotate through the drive shaft 22. The connecting shaft 23 drives the sorting screen 1 to rotate. The screen 1 is flipped over, changing the upward-facing side so that the side with the stuck concrete raw materials is facing down. The vibrating frame 11 vibrates, shaking the stuck concrete raw materials out of the sorting screen 1. After the stuck concrete raw materials are cleared, the dual-shaft motor 18 drives the support plate 25 to move closer to the sorting screen 1 through the screw 19. The support plate 25 slides back to its original position, supporting the sorting screen 1, and the sorting of concrete raw materials can continue.
