Description

Technical Field

[0001] This utility model relates to the field of waste resource recycling technology, and more particularly to the field of recycling waste electrical appliances or household items, specifically to a large waste sorting and recycling bin. Background Technology

[0002] In recent years, waste sorting has become an important part of global environmental protection efforts. Many countries and regions have successively introduced relevant policies to promote the implementation of waste sorting. In China, since its official implementation in Shanghai in 2019, the waste sorting policy has gradually been promoted nationwide. While the standards and methods for waste sorting vary from place to place, they are generally divided into four categories: recyclables, hazardous waste, wet waste, and dry waste. Although public awareness and participation in waste sorting are constantly improving, many challenges remain in practice, such as insufficient dissemination of waste sorting knowledge, a lack of sorting facilities, and low enthusiasm among some residents. Furthermore, governments and communities are making continuous efforts to improve public participation and sorting accuracy through publicity and education, setting up sorting collection points, and providing sorting guidance.

[0003] The recycling of household waste not only helps reduce resource waste but also effectively reduces environmental pollution, especially the separate recycling of items containing metals and those that are not. Metal-containing items, such as used batteries, electronic products, and metal containers, can be refined and reused after sorting and recycling, reducing the demand for new resources and mitigating the environmental damage caused by mining and smelting processes. Recycling non-metallic items, such as plastics and paper, can also transform them into new products through reprocessing, thus forming a closed-loop economy and reducing the consumption of natural resources. Furthermore, the recycling and reuse of waste resources helps create economic value, promotes the development of a circular economy, and propels society towards sustainable development goals. Therefore, actively participating in waste sorting and resource recycling is not only a reflection of personal environmental awareness but also a fulfillment of social responsibility.

[0004] Currently, existing technologies rely on recycling bins to collect garbage and discarded items in residential communities. This results in most recyclable items, such as pure plastic and metal products, being sent to waste disposal stations, leading to low effective recycling rates and resource waste. To improve the recycling of valuable items, a device specifically designed for recycling discarded items is needed to prevent valuable waste from being discarded as household garbage and wasted. Utility Model Content

[0005] To address the issue of recycling household waste, this application provides a bulky waste sorting and recycling bin for targeted recycling of household waste, thereby improving the effective reuse of waste resources, reducing waste generation, and minimizing environmental pollution.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A bulky waste sorting and recycling bin includes an outer casing and a top cover that is detachably and fixedly installed on the outer casing. The outer casing has a window for depositing bulky waste. A lifting door for covering the window is slidably installed inside the outer casing and is driven to rise and fall by a lifting mechanism. Inside the outer casing, below the window, is a conveying mechanism for sorting and transporting bulky waste. Above the conveying mechanism is a detection coil for detecting the metallic properties of bulky waste, and a control module electrically connected to the detection coil, the lifting mechanism, and the conveying mechanism. The bottom of the outer casing contains storage boxes for storing metal and non-metal items respectively.

[0008] Explanation of working principle and usage method / process:

[0009] When waste disposal is required, the control module, triggered manually or by a sensor, opens the lift door. The user then deposits the waste through the window into the outer container. The waste first rests on the conveyor mechanism, where a detection coil above the mechanism checks for metal components. If metal is detected, a signal is sent to the control module, which then moves the conveyor mechanism to the left or right. If no metal is detected, the signal is sent back to the control module, which moves the conveyor mechanism to the right or left / right. This process, based on the detection of metal, determines whether the conveyor moves the waste to the left or right, effectively separating metal and non-metal items. The waste then falls naturally into the metal and non-metal storage bins below.

[0010] To better classify the waste and store items containing metal or purely non-metallic materials separately, thereby improving the efficiency of subsequent processing, the conveying mechanism preferably includes a mounting frame fixedly installed on an outer casing. Conveying roller A and conveying roller B are horizontally mounted on the mounting frame. Conveying roller A consists of multiple rotating drums rotatably mounted on the mounting frame. Each drum is driven by a first driver mounted on the mounting frame. Conveying roller B has the same structure and driving method as conveying roller A and is driven by a second driver. The rotation directions of conveying roller A and conveying roller B are always consistent. This invention provides a structure for conveying using rotating drums. The entire conveying mechanism has multiple rotating drums, all located on the same plane, to facilitate material transport. When all drums rotate clockwise, the material moves to the left; conversely, when all drums rotate counterclockwise, the material moves to the right. This effectively solves the problem of item classification through transport in different directions. Of course, the conveying mechanism provided in this application includes multiple rotating drums controlled in two groups: the first driver drives conveying roller A (the first group), and the second driver drives conveying roller B (the second group). Of course, this is only one preferred conveying method provided by this utility model. The conveying roller can also be replaced with a conveyor belt, and one or two drivers can be used for driving. Those skilled in the art can also use other effective conveying mechanisms to achieve conveying. However, it is worth noting that since the material recycling bin is an unmanned device, the reliability of the structure is crucial. For example, with a conveyor belt, if there is a loose connection between the conveyor belt and the drive roller, the conveyor belt cannot effectively convey materials, and its reliability is lower than that of a rotary drum structure.

[0011] To better address the sorting and conveying of waste, preferably, at least one end of any rotating drum is fixedly connected to a driven gear, and a reversing gear meshes between two adjacent driven gears. The output shaft of the first driver is provided with a drive gear that meshes with the driven gear at the end of any rotating drum in conveying roller A, so that each rotating drum in conveying roller A rotates synchronously in the same direction.

[0012] As another way to achieve classified transportation, preferably, at least one end of any rotating drum is fixedly connected to a driven sprocket, and an active sprocket is provided on the output shaft of the first driver. The active sprocket is driven by a chain to the driven sprocket at the end of each rotating drum in the conveying roller A, so that each rotating drum rotates synchronously in the same direction.

[0013] To balance the convenience of delivery with the relative airtightness of the recycled items storage, preventing them from being eroded and contaminated by external rainwater, dust, and pollution, the lifting mechanism preferably includes a third drive fixedly installed inside the outer casing. The third drive is connected to the lifting door via a linkage mechanism, a lead screw mechanism, and a cylinder, and drives the lifting door to move up and down to open / close the window.

[0014] As one of the preferred structures for lifting drive, preferably, the linkage mechanism includes a first link and a second link hinged to each other. The lower ends of the first link and the second link are respectively hinged to sliders via a second pin and a first pin. The sliders are slidably installed in a slide rail, which is fixedly connected to the lifting door. The upper end of the first link is hinged to a support fixedly installed on the outer casing. The upper end of the second link is fixedly provided with an arc-shaped gear. The output end of the third driver is equipped with a drive gear that is driven and connected to the arc-shaped gear. The arc-shaped gear is driven by the third driver to move the lifting door up and down.

[0015] To prevent the detection coil from contacting the object being disposed of, preferably, a crossbeam is provided on the inner wall of the box top cover, and a detection coil for detecting whether large discarded items contain metal is suspended under the crossbeam. The vertical distance between the detection coil and the conveying mechanism is greater than the vertical height of the window.

[0016] To facilitate the separate collection and retrieval of waste items and to prevent collision damage to the outer box during the disposal process, preferably, the lower part of the outer box is provided with a left and a right door for retrieving the storage box, and a collision-proof protective plate is also provided between the outer box and the storage box.

[0017] Beneficial effects:

[0018] 1. This utility model uses a metal detection coil to detect whether the placed items contain metal as a classification standard, and classifies the items into different storage boxes according to whether they contain metal or are purely non-metallic. This reduces the subsequent classification workload and enables targeted recycling of metals.

[0019] 2. This utility model uses the metal signal detected by the detection coil as the control signal for the rotation direction of the conveying mechanism, which can improve the autonomy and efficiency of classification and effectively target the recycling of metal objects.

[0020] 3. This utility model is designed for the recycling of large waste items, which can effectively reduce the space occupied by existing household waste bins and prevent items such as old flashlights, small fans, toys, and metal / non-metal tableware from occupying the space of household waste bins, making it difficult to recycle valuable items, thus solving the problem of low effective space utilization of household waste bins.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this application, it should be noted that the use of terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when the product is in use. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of terms such as "first" and "second" in the description of this application is only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this application does not imply that the component is required to be absolutely horizontal or suspended, but rather that it may be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it may be slightly tilted.

[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] Example 1:

[0039] This embodiment provides a bulky waste sorting and recycling bin; see the attached instruction manual. Figures 1-8 The internal and external structures shown include an outer casing 2, a detachable and fixed top cover 1 fixedly installed on the outer casing 2, a window 5 for disposing of large waste items on the outer casing 2, a sliding door 10 for covering the window 5 inside the outer casing 2, the lifting door 10 being driven to rise and fall by a lifting mechanism 9; a conveying mechanism 8 for sorting and conveying large waste items is located below the window 5 inside the outer casing 2, a detection coil 7 for detecting the metallic properties of large waste items is located directly above the conveying mechanism 8, and a control module electrically connected to the detection coil 7, the lifting mechanism 9 and the conveying mechanism 8; and storage boxes for storing metal items and non-metal items are located at the bottom inside the outer casing 2.

[0040] Explanation of working principle and usage method / process:

[0041] When waste disposal is required, the control module, triggered manually or by a sensor, opens the lifting door 10. The person disposing of waste throws it into the outer container 2 through window 5. The waste is first placed on the conveyor mechanism 8. At this time, the detection coil 7 above the conveyor mechanism 8 detects whether the disposed item contains metal. If metal is detected, a signal is sent to the control module, which drives the conveyor mechanism 8 to move to the left / right. If no metal is detected, a signal is sent to the control module, which drives the conveyor mechanism 8 to move to the right / left / right. This achieves the purpose of separating items into metal and non-metal categories based on the detection of metal signals. Items then fall naturally into the metal and non-metal storage boxes below for storage.

[0042] The detection structure and principle of the detection coil 7 can adopt existing metal detectors or existing detection modules. In this embodiment, an example such as... Figures 6-7 The detection coil 7 shown adopts a structure in which three coils are placed side by side. The driving circuit of the detection coil 7 is integrated into the control module. The driving circuit used in this embodiment is as follows: Figure 9 As shown, this is implemented using a chip based on NE555P. In the figure, P1 is the power interface, P2 is the connection between the two ends of the detection coil 7, and P3 is the buzzer / light indicator interface. Of course, this is just one way to implement it based on the NE555P chip. Other chips and circuits can also be used for driving. This should not be interpreted as a limitation on the working driving circuit of the detection coil 7.

[0043] Example 2:

[0044] This embodiment is a further optimization based on Embodiment 1, and further refers to the appendix to the specification. Figures 1-9 As shown, in order to better classify the disposed waste and store it separately according to whether it contains metal or is purely non-metallic, thereby improving the efficiency of subsequent processing, in this embodiment, the conveying mechanism 8 includes a mounting frame 81 fixedly installed on the outer casing 2. Conveying rollers A82 and B84 are horizontally mounted on the mounting frame 81. Conveying roller A82 consists of multiple rotating drums rotatably mounted on the mounting frame 81. Each rotating drum is driven by a first driver 83 mounted on the mounting frame 81. The structure and driving method of conveying roller B84 are the same as those of conveying roller A82, and it is driven by a second driver 85. The rotation directions of conveying rollers A82 and B84 are always consistent. This utility model provides a structure for conveying using rotating drums. The entire conveying mechanism 8 has multiple rotating drums, all located on the same plane, to facilitate material conveying. When all rotating drums rotate clockwise, the material moves to the left; conversely, when all rotating drums rotate counterclockwise, the material moves to the right. In this way, the problem of item classification can be effectively solved by transporting items in different directions. Of course, the conveying mechanism 8 provided in this application includes multiple rotating drums controlled in two groups. The first driver 83 drives the conveying roller A82 as the first group; the second driver 85 drives the conveying roller B84 as the second group. Of course, this is only one preferred conveying method provided by this utility model. The conveying rollers can also be replaced with a conveyor belt, and one or two drivers can be used for driving. Those skilled in the art can also use other effective conveying mechanisms to achieve conveying. However, it is worth noting that since the material recycling bin is an unmanned device, the reliability of the structure is crucial. For example, in the case of a conveyor belt, if there is loosening between the conveyor belt and the drive roller, the conveyor belt cannot effectively convey materials, and its reliability is lower than that of the rotating drum structure.

[0045] To better address the sorting and transport of waste, this embodiment provides a specific structure in which at least one end of any rotating drum is fixedly connected to a driven gear, and a reversing gear meshes between two adjacent driven gears. The output shaft of the first driver 83 is provided with a drive gear that meshes with the driven gear at the end of any rotating drum in the conveying rollers A82, so that each rotating drum in the conveying rollers A82 rotates synchronously in the same direction.

[0046] As another way to achieve classified transportation, this embodiment also provides another driving structure, in which at least one end of any rotating drum is fixedly connected to a driven sprocket, and an active sprocket is provided on the output shaft of the first driver 83. The active sprocket is driven to be connected to the driven sprocket at the end of each rotating drum in the conveying roller A82 through a chain, so that each rotating drum rotates synchronously in the same direction.

[0047] Example 3:

[0048] This embodiment is an optimized version of any of the above embodiments. Specifically, it is combined with the appendix. Figure 1 , Figure 6 and Figure 7 As shown, in order to balance the convenience of delivery and the relative airtightness of the storage of recycled items, so as to prevent them from being eroded and polluted by external rainwater, dust and dirt, the lifting mechanism 9 includes a third drive 91 that is horizontally slidably disposed inside the outer casing 2. The third drive 91 is connected to the lifting door 10 through a linkage mechanism, a lead screw mechanism and a cylinder and drives the lifting door 10 to move up and down to open / close the window 5.

[0049] As one of the preferred structures for lifting drive, in this embodiment, see... Figure 8 As shown, the linkage mechanism includes a first link 94 and a second link 95 hinged to each other. The lower ends of the first link 94 and the second link 95 are respectively hinged to sliders via a second pin 98 and a first pin 96. The sliders are slidably mounted within a slide rail 97, which is fixedly connected to the lifting door 10. The upper end of the first link 94 is hinged to a support 93 fixedly mounted on the outer casing 2. The upper end of the second link 95 is fixedly provided with an arc-shaped gear disk 92. The output end of the third driver 91 is equipped with a drive gear that is always driven by the arc-shaped gear disk 92. The third driver 91 drives the arc-shaped gear disk 92 to move the lifting door 10 up and down. The third driver 91 drives the arc-shaped gear disk 92, causing the upper end of the second link 95 to deflect. Since the first link 94 and the second link 95 are hinged to each other and the upper end of the first link 94 is hinged to the support 93 fixedly mounted on the outer casing 2... Since the hinge point between the first link 94 and the second link 95 is not fixed, the fulcrum or center of rotation of the arc-shaped gear disk 92 is not fixed. This is thanks to the fact that the third actuator 91 is slidably mounted on the outer housing 2, allowing it to maintain an effective driving connection with the arc-shaped gear disk 92 at all times. To ensure that the drive gear is always drivingly connected to the arc-shaped gear disk 92, the third actuator 91 needs an elastic mechanism that keeps the drive gear pressed against the arc-shaped gear disk 92, which can be achieved using a spring or a spring sheet. Under the drive of the third actuator 91, the angle between the first link 94 and the second link 95 changes, causing the slide rail 97 to move the lifting door 10 up and down to achieve the purpose of opening / closing the door.

[0050] To prevent the detection coil 7 from contacting the object being disposed of, in this embodiment, a crossbeam 6 is provided on the inner wall of the box top cover 1, and a detection coil 7 for detecting whether large discarded items contain metal is suspended under the crossbeam 6. The vertical distance between the detection coil 7 and the conveying mechanism 8 is greater than the vertical height of the window 5.

[0051] To facilitate the separate collection and retrieval of waste items and to prevent collision damage to the outer box 2 during the disposal process, preferably, the lower part of the outer box 2 is provided with a left box door 3 and a right box door 4 for retrieving the storage box, and a collision-proof protective plate 11 is also provided between the outer box 2 and the storage box.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
