Description

Technical Field

[0001] This application relates to the technical field of construction engineering, and in particular to the storage bins for solid waste and their usage methods. Background Technology

[0002] Construction projects generate a lot of solid waste, such as sand, gravel, scrap steel, and plastics. Therefore, solid waste disposal sites are set up during construction for centralized disposal.

[0003] In related technologies, to reduce dust generation, fixed waste storage bins are placed at designated waste disposal points during construction, and workers place the fixed waste into the storage bins.

[0004] Regarding the aforementioned technologies, the waste inside the stacking bins is mixed together and quite messy. Furthermore, the scrap steel and plastics within them can be recycled and reused, therefore, there is room for improvement in the aforementioned stacking methods. Summary of the Invention

[0005] In order to recycle and process scrap steel and plastics, this application provides a solid waste stacking container and a method for its use.

[0006] The solid waste storage bins and usage methods provided in this application adopt the following technical solution:

[0007] A solid waste storage container and its usage method include a container body with an inlet and a plurality of collection boxes for holding solid waste, wherein the plurality of collection boxes are slidably connected to the container body;

[0008] The box is equipped with a sand and gravel screening screen, a conveying assembly and a sorting assembly in sequence. The sand and gravel screening screen is located below the feed inlet, and below the sand and gravel screening screen is a collection box for storing mud and sand.

[0009] The conveying assembly has a gap for stones to fall, and a collection box for receiving stones is located below the conveying assembly.

[0010] The sorting assembly includes a rotating roller, a transmission plate rotatably connected to the rotating roller, and a support plate connected to the transmission plate. The support plate is equipped with a weight spring; when the weight of the support plate exceeds a preset value, the support plate tilts.

[0011] By adopting the above technical solution, after the waste enters the box from the feed inlet, it first falls onto the sand and gravel screening screen, where fine mud and sand are screened out. The waste then moves to the conveying component, where stones are screened out. Finally, the waste moves to the sorting component, where scrap steel and plastic are screened out. Different types of waste are stored in multiple collection boxes. The sorted stones, scrap steel, and plastic can be recycled and reused, saving resources.

[0012] Optionally, the conveying assembly includes a drive motor and several conveying rollers, with the output shaft of the drive motor connected to the conveying rollers; the several conveying rollers are staggered, and there are gaps between adjacent conveying rollers for the stones to fall.

[0013] By adopting the above technical solution, when the waste moves to the conveying component, the stones fall from the gap between two adjacent conveying rollers and enter the collection box, thereby screening out the stones.

[0014] Optionally, each of the transmission plates is provided with two fixed blocks, and the support plate is located between the two fixed blocks and rotatably connected to the fixed blocks; the weight spring is a torsion spring, and the torsion spring is sleeved on both ends of the support plate.

[0015] By adopting the above technical solution, the waste from the conveyor roller falls onto the support plate. When the waste falling onto the support plate is plastic, the plastic is too light to cause the torsion spring to rotate, so the support plate remains stationary, and the transmission plate drives the plastic forward. When the waste falling onto the support plate is scrap steel, the scrap steel is heavier, and the support plate is subjected to greater pressure, causing the torsion spring to deform, which causes the support plate to rotate and tilt. The scrap steel then slides off the support plate, thus separating the scrap steel and plastic in this way.

[0016] Optionally, the transmission plate is provided with a mounting block, the top of the mounting block is provided with an inwardly curved moving groove, the support plate has a moving block inserted into the moving groove, the moving block slides into the moving groove; the weight spring is a compression spring, the compression spring is located in the moving groove, and the end of the compression spring abuts against the moving block.

[0017] By adopting the above technical solution, under normal conditions, the support plate is perpendicular to the transmission plate under the action of the compression spring. When plastic falls on the support plate, because the plastic is relatively light, the compression spring is not compressed, the support plate remains unchanged and supports the plastic to move forward. When scrap steel falls on the support plate, because the scrap steel is relatively heavy, the compression spring is compressed, the moving block moves downward in the moving groove, causing the support plate to tilt, and the scrap steel slides off the support plate.

[0018] Optionally, each of the transmission plates may have one or more support plates, with the multiple support plates spaced apart on the transmission plate.

[0019] By adopting the above technical solution, shorter scrap steel is relatively lighter in weight, and some short scrap steel may weigh the same as longer plastic. Therefore, in order to further distinguish the short scrap steel, in this embodiment, a transmission plate is provided with two or more support plates. Longer plastic requires two or more support plates to support it, while shorter scrap steel only needs one support plate. In actual operation, the elastic force of the weight spring can be calculated and designed so that the support plate can also tip over when supporting shorter scrap steel.

[0020] Optionally, the box body is provided with a sealing plate and a flip plate at the feed inlet, the sealing plate and the flip plate are arranged opposite to each other and interlocked.

[0021] By adopting the above technical solution, the sealing plate and the flip plate are interlocked, making it difficult for dust inside the box to fly out from the feed inlet.

[0022] Optionally, the tilting plate is slidably connected to an extension plate, and the extension plate is elastically connected to the tilting plate; the extension plate has a bent portion that abuts against the sand and gravel screening mesh.

[0023] Optionally, a fixing plate is fixedly connected to the back of the flip plate, and a sliding cavity is formed between the flip plate and the fixing plate for the extension plate to slide. A return spring is provided in the sliding cavity of the fixing plate, one end of the return spring is connected to the fixing plate, and the other end is connected to the extension plate.

[0024] By adopting the above technical solution, under normal conditions, the flip plate and the sealing plate are interlocked, and the bent part of the extension plate abuts against the sealing plate. The extension plate improves the sealing between the sealing plate and the flip plate, making it difficult for dust inside the box to fly out. When waste falls from the feed inlet, the flip plate is opened under the gravity of the waste. The waste slides along the flip plate to the bent part of the extension plate. Then, the extension plate also slides down due to the gravity of the waste. The return spring is stretched until the bent part of the extension plate abuts against the sand and gravel screening screen. The waste slides from the extension plate onto the sand and gravel screening screen. After that, the extension plate moves into the sliding cavity under the action of the return spring, and the flip plate overlaps and is interlocked with the sealing plate under the action of the torsion spring.

[0025] In summary, this application includes at least the following beneficial technical effects:

[0026] 1. After the waste enters the box through the feed inlet, it first falls onto the sand and gravel screening screen, where fine sand and mud are screened out. The waste then moves to the conveying component, where stones are screened out. Finally, the waste moves to the sorting component, where scrap steel and plastic are screened out. Different types of waste are stored in multiple collection boxes. The sorted stones, scrap steel, and plastic can be recycled and reused, saving resources.

[0027] 2. As the waste moves to the conveying assembly, the stones fall through the gap between two adjacent conveyor rollers and into the collection box, thus screening out the stones;

[0028] 3. Under normal conditions, the support plate is perpendicular to the transmission plate under the action of the compression spring. When plastic falls onto the support plate, the compression spring is not compressed because the plastic is relatively light, and the support plate remains unchanged and supports the plastic to move forward. When scrap steel falls onto the support plate, the compression spring is compressed because the scrap steel is relatively heavy, and the moving block moves downward in the moving groove, causing the support plate to tilt and the scrap steel to slide off the support plate.

[0045] The present application will be further described in detail below with reference to the accompanying drawings.

[0046] This application discloses a solid waste storage container.

[0047] Example 1:

[0048] See Figure 1 The stacking box includes a box body 1 and several collection boxes 2. The top of the box body 1 has a feed inlet 11 for dumping waste. Several collection boxes 2 are placed inside the box body 1 to store different types of waste. The collection boxes 2 are slidably connected to the box body 1. When the waste inside the box body is full, the collection boxes 2 can be removed from the box body 1.

[0049] In this embodiment, the solid waste mainly consists of silt, stones, plastic, and scrap steel. Therefore, four collection boxes 2 are provided to collect silt, stones, plastic, and scrap steel respectively. Due to the specific nature of the construction site, the plastic and scrap steel in this embodiment are both in long strips.

[0050] See Figure 2 The box body 1 is provided with a sealing plate 12 and a flip plate 13 at the feed inlet 11. The sealing plate 12 is fixedly connected to the box body 1, and the flip plate 13 is rotatably connected to the box body 1. The sealing plate 12 and the flip plate 13 are arranged opposite to each other and are interlocked.

[0051] A torsion spring is provided at the rotating connection between the flip plate 13 and the box 1. Under normal conditions, the flip plate 13 is always locked with the sealing plate 12 by the action of the torsion spring. When waste is dumped into the feed inlet 11, the flip plate 13 is opened due to gravity, and the waste enters the box 1 from the feed inlet 11. Then, the flip plate 13 is locked back into the sealing plate 12 by the action of the torsion spring.

[0052] See Figure 3 and Figure 4 Since the waste poured in is all mixed together, in order to separate the various wastes, the inside of the container 1 is equipped with a sand and gravel screening screen 3, a conveying component 4 and a sorting component 5 in sequence. The sand and gravel screening screen 3 screens out fine mud and sand, the conveying component 4 screens out stones, and the sorting component 5 screens out plastics and scrap steel.

[0053] Specifically, the sand and gravel screening screen 3 is located below the feed inlet 11 and is inclined downwards. The sand and gravel screening screen 3 has mesh 31 for sand and mud to fall through, and the size of the mesh 31 is set according to the actual situation. The sand and mud collection box 2 is located below the sand and gravel screening screen 3, and the sand and mud that fall through the mesh 31 falls into the collection box 2.

[0054] See Figure 5 and Figure 6 In order to ensure that the waste in the feed inlet 11 can fall smoothly onto the sand and gravel screening screen 3, the tilting plate 13 is slidably connected to the extension plate 14, and the waste in the feed inlet 11 slides down the extension plate 14 onto the sand and gravel screening screen 3.

[0055] A fixed plate 131 is fixedly connected to the back of the flip plate 13. A sliding cavity 132 is formed between the flip plate 13 and the fixed plate 131 for the extension plate 14 to slide. The extension plate 14 is located in the sliding cavity 132. Furthermore, a return spring 133 is provided in the sliding cavity 132 on the fixed plate 131. The return spring 133 is a compression spring. One end of the return spring 133 is connected to the fixed plate 131, and the other end is connected to the extension plate 14. The extension plate 14 slides in the sliding cavity 132 through the return spring 133.

[0056] The end of the extension plate 14 away from the return spring 133 is bent upward to form a bent portion 141. Under normal conditions, the flip plate 13 and the sealing plate 12 are interlocked, and the bent portion 141 of the extension plate 14 abuts against the sealing plate 12. The extension plate 14 improves the sealing between the sealing plate 12 and the flip plate 13, making it difficult for dust inside the box 1 to fly out. When the waste falls from the feed inlet 11, the flip plate 13 is opened under the gravity of the waste. The waste slides along the flip plate 13 to the bent portion 141 of the extension plate 14. Then the extension plate 14 also slides downward due to the gravity of the waste. The return spring 133 is stretched until the bent portion 141 of the extension plate 14 abuts against the sand and gravel screening screen 3. The waste slides from the extension plate 14 onto the sand and gravel screening screen 3. After that, the extension plate 14 moves into the sliding cavity 132 under the action of the return spring 133, and the flip plate 13 overlaps and is interlocked with the sealing plate 12 under the action of the torsion spring.

[0057] See Figure 7 and Figure 8 The conveying component 4 connects to the lower end of the sand and gravel screening screen 3, and waste that does not fall through the mesh 31 of the sand and gravel screening screen 3 moves to the conveying component 4. The waste here mainly consists of stones, plastics, and scrap steel.

[0058] The conveying assembly 4 includes a drive motor 41 and several conveying rollers 42. The drive motor 41 is fixed to the housing 1, and its output shaft is connected to the conveying rollers 42, thus driving the rollers 42 to rotate. One or more drive motors 41 can be used. If only one drive motor is used, it drives several conveying rollers 42 to rotate together via a gear set 43. If multiple drive motors are used, each drive motor 41 corresponds to one conveying roller 42. In this embodiment, only one drive motor 41 is used.

[0059] Several conveyor rollers 42 are staggered, specifically arranged as follows: the conveyor rollers 42 are divided into several rows, and there are gaps 44 between the conveyor rollers 42 in each row for stones to fall; the positions of the conveyor rollers 42 in adjacent rows are different. For example, each row has five positions of conveyor rollers 42, numbered 1-5. Then, the first row has conveyor rollers 42 at positions 1, 3, and 5; the second row has conveyor rollers 42 at positions 2 and 4; the third row is the same as the first row, and so on.

[0060] Since the conveyor rollers 42 are powered by the drive motor 41, all conveyor rollers 42 in the same horizontal row are driven by the same shaft. In order to prevent the shaft between two adjacent conveyor rollers 42 in the same horizontal row from blocking the stones, the shaft that drives the conveyor rollers 42 to rotate is bent and forms a crankshaft 45, so that the crankshaft 45 is less likely to block the stones from falling through the gap 44.

[0061] Below the conveyor roller 42 is a collection box 2 for storing stones, and stones falling through the gap 44 enter the collection box 2.

[0062] See Figure 9 , Figure 10 and Figure 11 Waste that did not fall through the gap 44 of the conveyor roller 42 moves to the sorting component 5. The waste here is mainly plastic and scrap steel. The plastic and scrap steel are screened by the sorting component 5.

[0063] The sorting assembly 5 includes a rotating roller 51, several transmission plates 52 connected to the rotating roller 51, and a support plate 53 connected to the transmission plates 52. The support plate 53 is equipped with a weight spring 54, which is used to screen plastic or scrap steel.

[0064] Two rotating rollers 51 are provided. The rotating rollers 51 are driven by a motor, which is fixed to the housing 1. Two adjacent transmission plates 52 are rotatably connected. Several transmission plates 52 are connected end to end to form a ring and are sleeved on the two rotating rollers 51. The rotating rollers 51 are provided with protrusions 511, and the transmission plates 52 are provided with grooves 521. After the rotating rollers 51 rotate, the protrusions 511 are embedded in the grooves 521, thereby causing the rotating rollers 51 to drive the transmission plates 52 to move.

[0065] The side of the transmission plate 52 away from the rotating roller 51 is connected to two fixed blocks 522 by screws. The two ends of the support plate 53 have rotating shafts 531. The two rotating shafts 531 are respectively inserted into the two fixed blocks 522, so that the support plate 53 is rotatably connected to the fixed blocks 522, that is, the support plate 53 can rotate on the fixed blocks 522.

[0066] The weight spring 54 is a torsion spring, which is sleeved on the rotating shaft 531. The force-applying rod of the torsion spring is connected to the fixed block 522, and the force-receiving rod of the torsion spring is connected to the support plate 53. The torsion spring applies force to the support plate 53 to keep the support plate 53 in balance. Under normal conditions, the support plate 53 is perpendicular to the transmission plate 52.

[0067] Waste from conveyor roller 42 falls onto support plate 53. When plastic falls onto support plate 53, its light weight prevents the torsion spring from rotating, so support plate 53 remains stationary, and transmission plate 52 drives the plastic forward. When scrap steel falls onto support plate 53, its heavier weight causes the torsion spring to deform under greater pressure, causing support plate 53 to rotate and tilt, and scrap steel to slide off support plate 53.

[0068] Therefore, there are collection boxes 2 on the lower left and lower right of the sorting component 5. The collection box 2 located on the lower left is for storing plastic, and the collection box 2 located on the lower right is for storing scrap steel.

[0069] In addition, to facilitate the transport of plastics, the upper part of the sorting component 5 is tilted to the left so that the plastics are less likely to slip off the support plate 53 when they fall on it.

[0070] Example 2:

[0071] The difference from Embodiment 1 lies in the different structures of the support plate 53 and the weight spring 54 in the sorting assembly 5.

[0072] See Figures 12-15 The transmission plate 52 is provided with two or more support plates 53, and the number of support plates 53 on adjacent transmission plates 52 is different.

[0073] The transmission plate 52 is provided with two fixed blocks 522, and the support plate 53 is rotatably connected between the two fixed blocks 522, so that the support plate 53 can rotate on the fixed blocks 522.

[0074] A mounting block 55 is provided on the transmission plate 52 below the support plate 53. The top of the mounting block 55 has an inwardly curved moving groove 551. The bottom of the support plate 53 is integrally provided with a moving block 532 that inserts into the moving groove 551. The moving block 532 slides into the moving groove 551. In this embodiment, the weight spring 54 is a compression spring, which is located in the moving groove 551, and its end abuts against the moving block 532.

[0075] Under normal conditions, the support plate 53 is perpendicular to the transmission plate 52 under the action of the compression spring. When plastic falls onto the support plate 53, the compression spring is not compressed because the plastic is relatively light, and the support plate 53 remains unchanged and supports the plastic to move forward. When scrap steel falls onto the support plate 53, the compression spring is compressed because the scrap steel is relatively heavy, and the moving block 532 moves downward in the moving groove 551, causing the support plate 53 to tilt and the scrap steel to slide off the support plate 53.

[0076] This embodiment achieves essentially the same effect as Embodiment 1, with the added advantage of being able to distinguish shorter pieces of scrap steel. Shorter pieces of scrap steel are relatively lighter, and some may even weigh the same as longer pieces of plastic. Therefore, to further differentiate between shorter pieces of scrap steel, in this embodiment, one transmission plate 52 is equipped with two or more support plates 53. Longer pieces of plastic require two or more support plates 53 for support, while shorter pieces of scrap steel only require one support plate 53. In actual operation, the elastic force of the weight spring 54 can be calculated and designed so that the support plate 53 can also tip over when supporting shorter pieces of scrap steel.

[0077] The implementation principle of the solid waste stacking box in this application embodiment is as follows: When the waste is placed in the feed inlet 11, the tilting plate 13 moves the waste to the sand and gravel screening screen 3, where fine mud and sand are screened out. Then the waste moves along the sand and gravel screening screen 3 to the conveying component 4, where stones are screened out. Then the waste moves to the sorting component 5, where scrap steel and plastic are screened out.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
