Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment technology, specifically a recycling concrete fragment sorting device. Background Technology

[0002] Concrete fragments are a type of construction waste that urgently needs to be processed. Such construction waste is generally recycled and reused after specific processing procedures. Recycled concrete fragment sorting is a necessary equipment in concrete recycling processes. The sorting device separates concrete fragments of different sizes. Currently, in concrete fragment sorting, concrete fragments need to be manually poured onto the sorting device. However, manually poured concrete fragments tend to be concentrated in one area of ​​the sorting device. Since the screen area of ​​the sorting device is large, the concentration of concrete fragments in one place will prevent the other screen areas of the sorting device from being used effectively, thus greatly reducing the efficiency and effectiveness of concrete fragment sorting. Therefore, a recycled concrete fragment sorting device is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a sorting device for recycled concrete fragments to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a recycled concrete fragment sorting device, comprising a sorting component, and further comprising:

[0005] Vibration assembly, which is installed on the sorting assembly;

[0006] A buffer component is installed on the sorting component;

[0007] The sorting assembly includes a sorting box. A collection chamber 1 is located on the right side of the sorting box, a collection chamber 2 is located in the center of the sorting box, and a collection chamber 3 is located on the left side of the sorting box. Three fixed frames are movably fitted above the collection chambers 1, 2, and 3 inside the sorting box. Several partitions 1 are hinged inside each fixed frame and located above the collection chamber 1, arranged along the interior of the fixed frame. Several partitions 2 are hinged inside each fixed frame and located above the collection chamber 2, arranged along the interior of the fixed frame. Several partitions 3 are fixedly connected inside each fixed frame and located above the collection chamber 3. Fixed blocks are connected to the front and rear of the sorting box. Movable blocks are movably fitted onto the outer surface of each fixed block. A feed box is connected to the inner side of each movable block. A drive motor is installed above and below the right side of the sorting box. The drive motor drives a movable shaft, and a cam is fixedly fitted onto the outer surface of the movable shaft. A protrusion above the cam is connected to the bottom of the feed box.

[0008] Preferably, the gap between the first partitions is smaller than the gap between the second partitions, and the gap between the second partitions is smaller than the gap between the third partitions.

[0009] Preferably, a tension spring is connected to the top of the fixed block, and the other end of the tension spring is connected to the inner cavity of the movable block.

[0010] Preferably, the vibration assembly includes two fixed plates, both of which are disposed at the front and rear of the sorting box. Three mounting plates are movably connected to the top of the fixed plates, and the three mounting plates are respectively located above the partition plate. A limit rod is connected to the bottom of the mounting plate. The bottom end of the limit rod extends to the bottom of the fixed plate and is connected to a connecting plate. A straight spring is sleeved on the outer surface of the limit rod. One end of the straight spring is connected to the fixed plate, and the other end of the straight spring is connected to the connecting plate. A hemispherical block is connected to the bottom of the connecting plate, and the connecting plate is connected to the fixed frame.

[0011] Preferably, mounting blocks are connected to the front and rear of the inner cavities of the first, second, and third collection cavities. A cylindrical wheel is movably fitted inside the mounting block, and several semi-circular blocks are connected around the outer surface of the cylindrical wheel and located below the hemispherical blocks.

[0012] Preferably, the number of semicircular blocks 1 surrounding the surface of the cylindrical wheel inside the second collection chamber is two-thirds of the number of semicircular blocks 1 surrounding the surface of the cylindrical wheel inside the third collection chamber, and the number of semicircular blocks 1 surrounding the surface of the cylindrical wheel inside the third collection chamber is two-thirds of the number of semicircular blocks 1 surrounding the surface of the cylindrical wheel inside the second collection chamber.

[0013] Preferably, the other end of the movable shaft extends into the interior of the first collection chamber, and the interior of the movable shaft is fixedly sleeved with the cylindrical wheel inside the first collection chamber. The cylindrical wheels inside the third and second collection chambers are both fixedly sleeved with round rods. A movable arm is fixedly sleeved on the right side of the outer surface of the round rod. A fixed arm is fixedly sleeved on the left end of the outer surface of the movable shaft and the round rod. A round shaft is fixedly sleeved inside the movable arm, and one end of the round shaft extends into the interior of the fixed arm and is movably sleeved with the interior of the fixed arm.

[0014] Preferably, the buffer assembly includes a mounting frame, which is installed on the left side of the fixed frame. A fixed shaft is fixedly connected inside the mounting frame. A buffer block located above the gap between partition one or partition two is movably sleeved on the outer surface of the fixed shaft. Several buffer blocks are provided. An arc-shaped spring is connected to the bottom of each buffer block. The arc-shaped spring is connected to the mounting frame. A compression block is connected to the inner side of each buffer block.

[0015] Preferably, the other end of the partition is connected to a push block and the other end of the push block extends to the outside of the fixed frame. The push block can swing inside the fixed frame. One side of the push block is connected to a tension spring. Each adjacent push block is connected to a tension spring and is elastically supported on the inner wall of the fixed frame by the tension spring.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, by setting up a movable block, a feeding box, and a cam, allows the operator to pour concrete fragments into the feeding box. The concrete fragments will flow downwards along the feeding box and be discharged through the discharge port at the bottom of the feeding box. Due to the operation of the drive motor, the movable shaft can drive the cam to rotate, and as the cam rotates, it squeezes the protrusion. The protrusion drives the collection chamber and the sorting box to vibrate up and down along the outside of the fixed block. At this time, the tension spring will have a quick reset effect, vibrating and spreading the concrete fragments inside the feeding box, while accelerating the discharge of the concrete fragments onto the partition plate. Since the width of the discharge port of the feeding box is smaller than the width of the inlet of the feeding box, the vibration of the feeding box can make the concrete fragments spread evenly during discharge, thus preventing them from piling up in one place. This allows the concrete fragments to evenly cover each screen surface, thereby improving the sorting efficiency of the concrete fragments.

[0018] 2. This invention, by setting up a cylindrical wheel and a semi-circular block, allows the cylindrical wheel to drive the semi-circular block to rotate due to the rotation of the movable shaft. This rotation, via the fixed arm, drives the cylindrical wheel and semi-circular block inside the collecting chambers three and two to rotate along the interior of the mounting block. The rotation of the semi-circular block compresses and pushes the hemispherical block, connecting plate, fixed frame, limiting rod, and mounting plate to reciprocate up and down. At this time, the straight spring accelerates the reset of the fixed frame, causing the fixed frame, partition one, partition two, and partition three to vibrate, preventing some concrete fragments from getting stuck in the gaps. Since the number of concrete fragments above partition one is greater than those above partition two and partition three, the rotation of the semi-circular block makes the vibration frequency of partition one greater than that of partition two, and partition two greater than that of partition three. This accelerates the sorting of concrete fragments by partitions two and partition one, further improving the sorting efficiency of concrete fragments.

[0019] 3. This invention, by setting up a buffer block, an arc-shaped spring, and a pusher block, addresses the issue that during the downward rolling of concrete fragments, due to the irregular surface of the fragments, some fragments of a certain size that should be sorted cannot be properly sorted because of their irregular surface. These fragments will get stuck at or be blocked by the buffer block during the fall. As larger fragments roll down, they will be cushioned by the buffer block. When they come into contact with the buffer block, they can squeeze the buffer block to rotate along the fixed axis. This can cause the squeezing block to squeeze the pusher block and the partition plate one to slightly stretch along the axis hinged to the fixed frame. At this time, the tension spring two is stretched, thereby widening the gap in the middle of the partition plate one. This makes it easier to sort out the fragments blocked by the buffer block, further avoiding omissions in the sorting process and improving the sorting effect. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 14 As shown, this embodiment of the invention provides a sorting device for recycled concrete fragments, including a sorting component 1, and further comprising:

[0037] Vibration component 2 is mounted on sorting component 1;

[0038] Buffer component 3 is disposed on sorting component 1;

[0039] The sorting assembly 1 includes a sorting box 11. A collection chamber 12 is located on the right side of the sorting box 11, a collection chamber 2 13 is located in the center of the sorting box 11, and a collection chamber 3 14 is located on the left side of the sorting box 11. Three fixed frames 15 are movably fitted above the collection chambers 12, 2 13, and 3 14 inside the sorting box 11. Several partitions 16 are hinged inside the fixed frames 15 and located above the collection chambers 12. The partitions 16 are arranged along the interior of the fixed frames 15. Several partitions 2 17 are hinged inside the fixed frames 15 and located above the collection chambers 2 13. In the sorting box 11, partition 2 17 is arranged along the inside of the fixed frame 15. Several partition 3 18 are fixedly connected inside the fixed frame 15 and located above the collection chamber 3 14. Fixed blocks 110 are connected to the front and rear sides of the sorting box 11. Movable blocks 111 are movably sleeved on the outer surface of the fixed blocks 110. Feed box 112 is connected to the inner side of the movable blocks 111. Drive motor 114 is installed on the upper and lower right side of the sorting box 11. Movable shaft 115 is driven and connected by drive motor 114. Cam 116 is fixedly sleeved on the outer surface of the movable shaft 115. Protrusion 19 located above cam 116 is connected to the bottom of the feed box 112.

[0040] Concrete fragments are poured into the feed box 112. The concrete fragments will flow downwards along the feed box 112 and be discharged through the discharge port at the bottom of the feed box 112. Due to the operation of the drive motor 114, the movable shaft 115 drives the cam 116 to rotate. As the cam 116 rotates, it squeezes the protrusion 19. The protrusion 19 drives the collection chamber 12 and the sorting box 11 to vibrate up and down along the outside of the fixed block 110, which vibrates and spreads the concrete fragments inside the feed box 112. At the same time, it accelerates the discharge of the concrete fragments onto the partition plate 16. Since the width of the discharge port of the feed box 112 is smaller than the width of the feed port of the feed box 112, the vibration of the feed box 112 can make the concrete fragments spread evenly during discharge, so as not to form a pile-up in one place. In this way, the concrete fragments can be evenly covered on each screen surface.

[0041] As shown in the figure, in one embodiment, the gap between partition 16 is smaller than the gap between partition 217, and the gap between partition 217 is smaller than the gap between partition 318.

[0042] The working principle and beneficial effects of the above technical solution are as follows: partition 16, partition 2 17 and partition 3 18 are set up. Due to the design of partition 16, smaller gravel can be sorted out and fall into collection chamber 12. Due to the design of partition 2 17, gravel between the gap range of partition 16 and the gap range of partition 3 18 can be sorted out and fall into collection chamber 2 13. Due to the design of partition 3 18, larger gravel can be sorted out and fall into collection chamber 3 14.

[0043] As shown in the figure, in one embodiment, a tension spring 113 is connected to the top of the fixed block 110, and the other end of the tension spring 113 is connected to the inner cavity of the movable block 111.

[0044] The working principle and beneficial effects of the above technical solution are as follows: When the movable block 111 moves upward, the tension spring 113 can be stretched. Due to the elastic recovery effect of the tension spring 113, the movable block 111 can be subjected to a downward pulling force, so as to facilitate the rapid reset of the feed box 112.

[0045] As shown in the figure, in one embodiment, the vibration assembly 2 includes two fixed plates 21, both of which are disposed at the front and rear of the sorting box 11. Three mounting plates 22 are movably connected to the top of the fixed plates 21, and the three mounting plates 22 are respectively located above the partition 16. The bottom of the mounting plates 22 is connected to a limit rod 23, the bottom end of which extends to the bottom of the fixed plates 21 and is connected to a connecting plate 213. A straight spring 24 is sleeved on the outer surface of the limit rod 23. One end of the straight spring 24 is connected to the fixed plate 21, and the other end of the straight spring 24 is connected to the connecting plate 213. A hemispherical block 25 is connected to the bottom of the connecting plate 213, and the connecting plate 213 is connected to the fixed frame 15.

[0046] The working principle and beneficial effects of the above technical solution are as follows: When the hemispherical block 25 is subjected to compressive force, the connecting plate 213, the fixed frame 15, the limiting rod 23 and the mounting plate 22 can move up and down reciprocally. At this time, the straight spring 24 can accelerate the reset of the fixed frame 15, thereby causing the fixed frame 15, partition 16, partition 27 and partition 3 18 to vibrate, so as to prevent some concrete fragments from getting stuck in the gap.

[0047] As shown in the figure, in one embodiment, mounting blocks 26 are connected to the front and rear of the inner cavities of collecting cavity 12, collecting cavity 23 and collecting cavity 34. A cylindrical wheel 27 is movably sleeved inside the mounting block 26. A plurality of semi-circular blocks 28 are connected around the outer surface of the cylindrical wheel 27 and are located below the hemispherical block 25.

[0048] The working principle and beneficial effects of the above technical solution are as follows: a semicircular block 28 is set up. Due to the operation of the drive motor 114, the movable shaft 115 can rotate, and the movable shaft 115 drives the cylindrical wheel 27 to drive the semicircular block 28 to rotate along the inside of the mounting block 26, thereby driving the semicircular block 28.

[0049] As shown in the figure, in one embodiment, the number of semicircular blocks 28 surrounding the surface of the cylindrical wheel 27 inside the second collection cavity 13 is two-thirds of the number of semicircular blocks 28 surrounding the surface of the cylindrical wheel 27 inside the third collection cavity 14, and the number of semicircular blocks 28 surrounding the surface of the cylindrical wheel 27 inside the third collection cavity 14 is two-thirds of the number of semicircular blocks 28 surrounding the surface of the cylindrical wheel 27 inside the second collection cavity 13.

[0050] The working principle and beneficial effects of the above technical solution are as follows: a semicircular block 28 is set up. Since the number of concrete fragments above the partition 16 is greater than that on the partition 27 and the partition 3 18, the rotation of the semicircular block 28 can make the vibration frequency of the partition 16 greater than that of the partition 27, and the vibration frequency of the partition 27 greater than that of the partition 3 18, thereby accelerating the sorting of concrete fragments by the partition 27 and the partition 16.

[0051] As shown in the figure, in one embodiment, the other end of the movable shaft 115 extends into the interior of the first collection chamber 12. The interior of the movable shaft 115 is fixedly sleeved with the cylindrical wheel 27 inside the first collection chamber 12. The cylindrical wheels 27 inside the third collection chamber 14 and the second collection chamber 13 are both fixedly sleeved with a round rod 210. The right side of the outer surface of the round rod 210 is fixedly sleeved with a movable arm 211. The left end of the outer surface of the movable shaft 115 and the round rod 210 is fixedly sleeved with a fixed arm 29. The interior of the movable arm 211 is fixedly sleeved with a round shaft 212. One end of the round shaft 212 extends into the interior of the fixed arm 29 and is movably sleeved with the interior of the fixed arm 29.

[0052] The working principle and beneficial effects of the above technical solution are as follows: The fixed arm 29 is set up so that the rotation of the movable shaft 115 can cause the cylindrical wheel 27 to drive the semi-circular block 28 to rotate. The fixed arm 29 can drive the cylindrical wheel 27 and the semi-circular block 28 inside the cylindrical shaft 212, the movable arm 211, the cylindrical rod 210, and the cylindrical wheel 27 and the semi-circular block 28 inside the collection chamber 3 14 and the collection chamber 2 13 to rotate along the inside of the mounting block 26.

[0053] As shown in the figure, in one embodiment, the buffer assembly 3 includes a mounting frame 31, which is mounted on the left side of the fixed frame 15. A fixed shaft 32 is fixedly connected inside the mounting frame 31. A buffer block 33 is movably sleeved on the outer surface of the fixed shaft 32, located above the gap between the first partition 16 or the second partition 17. Several buffer blocks 33 are provided. An arc spring 34 is connected to the bottom of the buffer block 33. The arc spring 34 is connected to the mounting frame 31. A compression block 37 is connected to the inner side of the buffer block 33.

[0054] The working principle and beneficial effects of the above technical solution are as follows: When the squeezing block 37 is set, the larger fragments will be buffered by the buffer block 33 as they roll down. When in contact with the buffer block 33, the squeezing block 37 can be squeezed to rotate along the fixed axis 32. At this time, the arc spring 34 is compressed. Due to the elastic recovery effect of the arc spring 34, the buffer block 33 will exert a reverse force on the fragments, thereby achieving the effect of unloading force and buffering the fragments as they roll down.

[0055] As shown in the figure, in one embodiment, the other end of the partition 16 is connected to a push block 35 and the other end of the push block 35 extends to the outside of the fixed frame 15. The push block 35 can swing inside the fixed frame 15. One side of the push block 35 is connected to a tension spring 36. Each adjacent push block 35 is connected to a tension spring 36 and is elastically supported on the inner wall of the fixed frame 15 by the tension spring 36.

[0056] The working principle and beneficial effects of the above technical solution are as follows: When the push block 35 is set, the push block 35 and the partition 16 can be slightly stretched along the axis hinged to the fixed frame 15 due to the rotation of the squeezing block 37. At this time, the tension spring 2 36 is stretched, which can expand the gap in the middle of the partition 16, thereby making it easier to sort out the fragments blocked by the buffer block 33, and further avoiding the omission of the sorting process.

[0057] Working principle and usage process:

[0058] During use, the operator pours concrete fragments into the feed box 112. The concrete fragments will flow downwards along the feed box 112 and be discharged through the discharge port at the bottom of the feed box 112. Due to the operation of the drive motor 114, the movable shaft 115 drives the cam 116 to rotate. As the cam 116 rotates, it squeezes the protrusion 19. The protrusion 19 drives the collection chamber 12 and the sorting box 11 to vibrate up and down along the outside of the fixed block 110. At this time, the tension spring 113 will have a quick reset effect, vibrating and spreading the concrete fragments inside the feed box 112, while accelerating the discharge of the concrete fragments onto the partition plate 16. Since the width of the discharge port of the feed box 112 is smaller than the width of the feed port of the feed box 112, the vibration of the feed box 112 can make the concrete fragments spread evenly during discharge, improving the sorting efficiency of the concrete fragments.

[0059] The rotation of the movable shaft 115 causes the cylindrical wheel 27 to drive the semicircular block 28 to rotate. This rotation, via the fixed arm 29, causes the cylindrical wheel 27 and semicircular block 28 inside the collecting chambers 14 and 13 to rotate along the interior of the mounting block 26. The rotation of the semicircular block 28 compresses and pushes the hemispherical block 25, connecting plate 213, fixed frame 15, limiting rod 23, and mounting plate 22 to reciprocate up and down. At this time, the straight spring 24 accelerates the reset of the fixed frame 15, causing the fixed frame 15, partition 16, partition 27, and partition 38 to vibrate, preventing concrete fragments from getting stuck in the gaps. Because the area above partition 16... The number of concrete fragments is greater than that on partitions 2 (17) and 3 (18). However, the slope of partition 1 (16) is gentler than that of partition 2 (17), and the slope of partition 2 (17) is gentler than that of partition 3 (18). This can reduce the speed at which the concrete fragments roll downwards to a certain extent, and prolong the time that the concrete fragments stay on partitions 2 (17) and 16. This ensures that the concrete fragments are completely sorted by partitions 2 (17) and 16, avoiding any omissions. Due to the rotation of the semicircular block 1 (28), the vibration frequency of partition 1 (16) is greater than that of partition 2 (17), and the vibration frequency of partition 2 (17) is greater than that of partition 3 (18). This can accelerate the sorting of concrete fragments by partitions 2 (17) and 16, further improving the sorting efficiency of concrete fragments.

[0060] As concrete fragments roll downwards, due to their irregular surface, some fragments that should be sorted cannot be properly separated. These fragments may get stuck or blocked by the buffer block 33 during their fall. As larger fragments roll down, they are cushioned by the buffer block 33. Upon contact with the buffer block 33, the fragments are compressed, causing it to rotate along the fixed axis 32 and compressing the arc spring 34. Due to the restoring elasticity of the arc spring 34, a reverse force is applied to the fragments through the buffer block 33, thus achieving [the desired effect]. This provides a force-relieving effect, thus buffering the fragments as they roll downwards, reducing their initial velocity upon impact with partition 17 or partition 18, and further extending the time the fragments remain on partitions 17 and 18 to prevent omissions during sorting. Simultaneously, when the buffer block 33 is squeezed and rotated, it can cause the squeezing block 37 to squeeze the push block 35 and partition 16 along the axis hinged to the fixed frame 15, causing a slight tension. At this time, the tension spring 36 is stretched, thereby widening the gap in the middle of partition 16, making it easier to sort out the fragments blocked by the buffer block 33, further avoiding omissions during the sorting process and improving the sorting effect.
