Waste sorting can effectively utilize waste, alleviate resource scarcity, and reduce environmental pollution. Generally, waste sorting is automated using a combination of visual sensors and image recognition technology.

[0003] However, the aforementioned technologies often suffer from problems such as low recognition accuracy and slow response speed when identifying and processing waste. In existing technologies, recognition accuracy is affected by factors such as light and environment, leading to inaccurate classification. Furthermore, visual sensors and image recognition algorithms have limitations in handling complex situations, as well as limitations in processing speed and computing power, resulting in a poor user experience and making it difficult to motivate people to sort waste. Consequently, the adoption rate of waste sorting and processing devices is low.

[0038] The following is in conjunction with the appendix Figure 1-8 The present invention will be described in further detail below.

[0039] This utility model discloses a high-efficiency waste sorting and processing device, comprising:

[0040] Waste disposal unit 101 is used to receive waste. It can adopt a device structure that can receive waste, such as the existing waste bin structure, which will not be described in detail here.

[0041] The visual recognition unit is used to acquire visual information of the waste received by the waste disposal unit 101. The visual recognition unit is a key part of the waste sorting and processing device and is responsible for distinguishing different types of waste. It will not be described in detail here.

[0042] The control unit classifies waste and generates classification instructions based on the visual information from the visual recognition unit. First, the control unit receives and analyzes the visual information from the visual recognition unit. Based on the processed visual information, the control unit makes judgments according to pre-programmed classification logic. Based on the results of the classification logic judgments, the control unit generates corresponding classification instructions. Typically, the connection between the output of the visual recognition unit and the input of the control unit can be a wired connection via a power cable or data cable, or a wireless connection via Bluetooth or a wireless network for data interaction. Preferably, in this embodiment, the connection between the output of the visual recognition unit and the input of the control unit is a wireless connection, which will not be elaborated further here.

[0043] The sorting unit receives waste from the waste disposal unit 101 and sorts it according to the sorting instructions issued by the control unit. The sorting unit receives the sorting instructions issued by the control unit and performs corresponding operations according to the sorting instructions. The sorting instructions cover the specific operational requirements of each execution component in the sorting unit, which will not be elaborated here. The output terminal of the control unit and the sorting unit are usually connected by a wire to ensure reliable transmission of the sorting instructions, which will not be elaborated here.

[0044] The storage unit is used to receive and store the sorted waste from the sorting unit. The storage unit is generally a trash can made of plastic, metal or composite material, and is used for temporary storage of waste. It will not be described in detail here.

[0045] In this embodiment, the classification unit includes:

[0046] The sorting tray 3 is rotatable and has a surface for receiving waste from the waste disposal unit 101. In common waste disposal devices, the drive motor serves as the power source for the rotation of the sorting tray 3. Its selection depends on factors such as the load characteristics, speed requirements, and working environment of the sorting tray 3. Commonly used motors are AC asynchronous motors, DC motors, or servo motors with good speed regulation performance, large starting torque, and high operating efficiency; these will not be elaborated further here. As shown in the figure, the sorting tray 3 includes a sorting tray body 301, a boss 302, a central shaft 303, a conical cover 304, and a flexible fabric 11 with gaps. The sorting tray body 301 is the core basic structure of the entire sorting tray 3, supporting and bearing other components. Its material generally requires a certain degree of wear resistance and corrosion resistance, such as stainless steel or high-strength plastics, and is capable of withstanding significant weight. The waste is easy to clean and will not be easily corroded by the chemicals in the waste; the protrusion 302 generally refers to the protruding part on the main body 301 of the sorting tray, which has a specific shape and plays a role in positioning, fixing or assisting in guiding the flow of waste to other components, which will not be described in detail here; the central shaft 303 has the characteristics of being flexible and having a certain degree of elasticity, which can better fit other components and ensure the sealing or buffering of the entire sorting tray during operation, preventing waste from leaking out from some gaps, which will not be described in detail here; the conical cover 304 is installed at the top of the central shaft 303, and is shaped like a cone, guiding waste into the sorting tray 3 or preventing waste from splashing out during operation, which will not be described in detail here; the flexible fabric 11 with gaps can prevent dust, debris and other small particles from accumulating on the contact surface of adjacent components, ensuring the normal operation of the sorting tray 3, which will not be described in detail here;

[0047] The pusher plate 5, having several units corresponding to the number of waste categories, is driven to push outwards radially from the inside of the sorting tray 3, thus pushing the sorted waste out of the tray, as shown in the figure. The number of pusher plates 5 corresponds to the number of waste categories. Currently, domestic waste sorting is mainly divided into four categories: recyclable waste, hazardous waste, kitchen waste, and other waste, which will not be elaborated further here. The pusher plate 5 includes a power source, a rod, an outer tube, a transmission device, and a limit switch. The power source is generally a motor, which transmits power to the rod through a transmission device such as a worm gear or gear. The rod is telescopic and is usually made of metal materials, such as stainless steel or aluminum alloy, providing a certain degree of strength and stability. The outer tube is used to wrap the rod, serving a protective and guiding function, while also preventing dust and debris from entering and affecting its normal operation. The limit switch is used to control the extension and retraction stroke of the rod, ensuring that it operates within a set range. When the motor receives the sorting command from the control unit, it starts to operate, driving the rod to perform linear extension and retraction within a certain range through the transmission device, pushing the waste out of the sorting tray, which will not be elaborated further here.

[0048] In this embodiment, the sorting unit further includes a waste dry and wet separation system 8. The waste dry and wet separation system 8 includes a filter disc 801 and a waste removal component. As shown in the figure, the main body of the filter disc 801 is a metal container with drainage holes. Its shape is round or square, and it is generally made of stainless steel, which has good corrosion resistance and strength and can withstand a certain weight and pressure. A filter screen is provided inside the main body of the filter disc 801, and the size of its pores is set according to actual needs. The bottom of the filter disc 801 is provided with a drainage pipe interface, which connects to a drainage pipe 802. This will not be described in detail here.

[0049] The waste disposal unit 101 includes a dry waste disposal inlet 1011 and a wet waste disposal inlet 1012. The dry waste disposal inlet 1011 directly reaches the sorting tray 3, and the wet waste disposal inlet 1012 directly reaches the filter tray 801. The liquid in the wet waste is filtered and discharged through the filter tray 801. The waste removal component is used to push the filtered waste on the filter tray 801 to the sorting tray 3. As shown in the figure, the waste disposal unit 101 includes a dry waste disposal inlet 1011 and a wet waste disposal inlet 1012, realizing the disposal of dry and wet waste. Separate disposal of waste facilitates classification and collection, improving waste treatment efficiency, which will not be elaborated further here; the dry waste disposal inlet 1011 is directly connected to the sorting tray 3, and the waste directly reaches the sorting tray 3 area for subsequent processing operations, which will not be elaborated further here; the wet waste disposal inlet 1012 is connected to the filter tray 801, the liquid of the wet waste is filtered through the filter tray 801 and discharged through the drainage pipe 802, and the solid part of the wet waste is pushed to the sorting tray 3 through the waste removal component for subsequent processing operations, which will not be elaborated further here;

[0050] The waste removal assembly includes a pusher plate 9 and a conveyor belt corresponding to the wet and dry waste separation system. The conveyor belt is connected to the sorting tray 3, and the wall of the dry waste inlet 1011 is provided with a notch 10111 that matches the conveyor belt, as shown in the figure. The pusher plate 9 in the waste removal assembly, corresponding to the wet and dry waste separation system, allows the solid parts in the wet waste to be transported to the subsequent processing unit in a timely manner, avoiding the accumulation of solid parts in the wet waste, clogging of the filter screen in the filter tray, and the generation of odors and bacterial growth. Further details are omitted here. The wet and dry waste separation system 8 is connected to the sorting tray 3 via a conveyor belt. The conveyor belt is a material conveying device widely used in industrial production, logistics transportation, and other fields, including horizontal conveyor belts, inclined conveyor belts, and vertical conveyor belts. Further details are omitted here. Preferably, in this embodiment, a [specific type of conveyor belt is used]. The horizontal conveyor belt 7, which will not be described in detail here, carries the solid portion of the wet waste pushed in by the pusher plate 9 corresponding to the wet and dry waste separation system through the notch 10111 on the cylinder wall of the dry waste inlet, which matches the conveyor belt, to the sorting tray 3 for subsequent sorting operations. By integrating the wet and dry waste separation system 8, the pusher plate 9, the horizontal conveyor belt 7, and the sorting tray 3 into a whole, the waste sorting device can accurately and orderly process different types of waste. From the proper collection and control of moisture in wet waste to the transportation and transfer of solid components in wet waste, and then to the comprehensive sorting on the sorting tray 3, each link works closely together, giving full play to its functional advantages, effectively improving the waste sorting efficiency and operational stability of the entire device, and laying a solid foundation for achieving the goal of efficient and environmentally friendly waste sorting and treatment.

[0051] In this embodiment, the storage unit includes several waste storage boxes 10, which are respectively set at the waste ejection position of the sorting tray 3 and the liquid waste discharge position of the filter tray 801. The storage unit is generally made of plastic, metal or composite materials. The several waste storage boxes 10 are set at the outlet of the dry / wet waste ejection channel and are precisely corresponding to the dry / wet waste ejection channel to ensure that the waste can fall accurately into the waste storage box 10, realize waste sorting and collection, facilitate subsequent waste processing, improve resource recycling rate and reduce environmental harm. Further details are omitted here.

[0052] In this embodiment, the push plate 5 includes a power source, a transmission device, and a push rod. The power source transmits power to the push rod through the transmission device, thereby extending and retracting the push rod. The power source is typically a motor, and the power is transmitted to the push rod through a transmission device such as a worm gear or gear. The push rod has a telescopic function and is usually made of metal materials, such as stainless steel or aluminum alloy, which has a certain strength and stability. When the motor receives the sorting command issued by the control unit, it starts to operate and drives the push rod to make a linear telescopic movement from the inside to the outside along the radial direction of the sorting plate through the transmission device, pushing the garbage out of the sorting plate. Further details are omitted here.

[0053] The pusher plate 5 is located inside the sorting tray 3 and is in contact with the conical cover cylinder 6 at the center of the sorting tray. The contact surface is provided with a flexible fabric 11 with gaps. The pusher plate 5, as a device that can provide linear reciprocating motion power, is located inside the sorting tray 3 and can be linked with other components on the sorting tray 3 to complete specific operations in the waste sorting process. Further details are omitted here. As shown in the figure, the pusher plate 5 is in contact with the conical cover cylinder 6 located at the center of the sorting tray. The conical cover cylinder 6 consists of a central shaft 303 and a conical cover 304. The conical cover 304 at the top of the cylinder is designed to guide the waste as it enters from the dry waste inlet 1011, preventing it from sliding down the sorting tray 3 in a suitable direction and preventing waste from accumulating on the top of the cylinder. It also prevents smaller pieces of waste or debris from entering. The waste entering the cylinder affects the normal operation of the sorting tray 3 and extends its service life, which will not be elaborated further here. The flexible fabric 11 with gaps is located at the contact surface between the push plate 5 and the conical cover cylinder 6. It can effectively absorb and disperse the impact force generated by the expansion and contraction of the push plate 5 during operation and the friction force that may be generated when the push plate 5 and the conical cover cylinder 6 are in contact. It avoids wear and deformation caused by rigid contact, extends the service life, and enhances the tightness of the fit. The design of the flexible fabric with gaps can prevent the waste from falling from the conical cover 304 to the push plate 5 at too fast speed, which would damage the push plate 5 and extend the service life of the push plate 5. It can also prevent dust, debris and other small particles from accumulating on the contact surface between the push plate 5 and the conical cover cylinder 6, ensuring the stable operation of the entire device and enabling it to continuously and efficiently complete the waste sorting work, which will not be elaborated further here.

[0054] In this embodiment, the waste disposal device also includes an outer cylinder 1, which covers the visual recognition unit, control unit, sorting unit and storage unit located inside the device. The outer cylinder 1, as the external structural part of the entire device, has the function of protecting the internal units, preventing external dust, rainwater and debris from entering the device and damaging the internal units, and extending the service life of the internal units. This will not be elaborated further here.

[0055] The outer cylinder 1 includes a top plate 11' and a cylinder wall 12'. The garbage disposal unit 101 is disposed on the top plate 11' of the outer cylinder. The cylinder wall on the side of the outer cylinder near the garbage dry and wet separation system has a notch 102 that matches the liquid garbage discharge port of the garbage dry and wet separation system. Disposing of the garbage disposal unit 101 on the top plate 11' of the outer cylinder conforms to people's daily garbage disposal habits and can make the most of the space of the outer cylinder 1. This avoids the space waste and the problem of affecting the overall stability of the garbage sorting device that may be caused by setting garbage disposal ports on the side or bottom of the outer cylinder 1. This will not be elaborated here. The notch 102 on the cylinder wall on the side of the outer cylinder near the garbage dry and wet separation system that matches the liquid garbage discharge port of the garbage dry and wet separation system is connected to the end of the drainage pipe 802, so that the liquid of the wet garbage is discharged to the corresponding garbage storage box 10, avoiding the generation of odor and the growth of bacteria due to the accumulation of moisture in the wet garbage. This will not be elaborated here.

[0056] In this embodiment, the visual recognition unit includes a camera 2 and an image processing unit. The camera 2 is used to capture images of the appearance of the waste. It is mounted on the outer cylinder wall 12' at a set height via a bracket and distributed on both sides of the sorting tray 3, as shown in the figure. The camera 2 is mounted on the outer cylinder wall 12' at a specific height via a bracket to avoid the situation where the installation height is too low, which would only capture a local area of ​​waste on the sorting tray 3, resulting in a limited field of view and difficulty in fully acquiring the appearance features of the waste, which would be detrimental to accurate identification of waste types. Alternatively, if the installation height is too high, although the field of view will be wider, the details of the waste in the image may become blurred, which would also affect the recognition effect. This will not be elaborated further here. The cameras 2 are distributed on both sides of the sorting tray 3, and shooting from both sides of the sorting tray 3 can acquire images of the appearance of the waste from different angles, complementing each other, thereby gaining a more comprehensive understanding of the characteristic information of the waste. By comprehensively analyzing the images acquired by the cameras 2 on both sides of the sorting tray, the accuracy of waste identification is improved, avoiding the occlusion problem that may occur due to a single perspective. At the same time, this layout also makes the structure compact and makes full use of the internal space of the device. This will not be elaborated further here. The image processing unit... The image processing unit processes the images acquired by the camera 2 and inputs the processed visual information of the waste to the control unit. Convolutional Neural Network (CNN) algorithms are commonly used in image processing, mimicking the working principle of the human visual system. A network structure is built using multiple convolutional layers, pooling layers, and fully connected layers to reduce data volume while retaining key features, enhancing the algorithm's anti-interference ability and improving recognition accuracy. Further details are omitted here. The transmission of the processed visual information of the waste from the image processing unit to the control unit typically uses either wired or wireless connections. Wired connections use data cables and offer stable data transmission and high bandwidth, suitable for large data volumes, such as the transmission of high-definition image recognition results and related detailed information. They are commonly used in large, fixed-location waste sorting devices. Wireless connections utilize Bluetooth or wireless networks, offering the advantages of no wiring and convenient connection, suitable for relatively short distances, facilitating remote monitoring and management of the waste sorting device. Further details are omitted here. Preferably, the transmission of the processed visual information of the waste from the image processing unit to the control unit uses a wired connection. Further details are omitted here.

[0057] The main component of the control unit is a microprocessor, which processes the visual information of the waste collected by the visual recognition unit and issues classification instructions to the classification unit based on the visual information. The microprocessor first receives the visual information of the waste collected by the visual recognition unit. The visual information usually includes the shape, color, material, weight, etc. of the waste and is transmitted to the control unit in the form of digital signals via wireless connection. Then, the microprocessor performs processing work based on its pre-set algorithm and intelligent logic judgment system, generates and issues classification instructions to the classification unit, which will not be elaborated here.

[0058] In this embodiment, the sorting tray 3 has four protrusions 302. Each protrusion 302 is tangent to the horizontal projection of the bottom edge of the sorting tray 3 and has an axial distance between them, extending downwards towards the corresponding storage unit, as shown in the figure. The protrusions 302 are evenly distributed around the sorting tray 3. At the point where the protrusions 302 are tangent to the horizontal projection of the bottom edge of the sorting tray 3, a curved baffle 305 of a certain height is provided. The baffle 305 is closely connected to and complements the protrusions 302, preventing garbage from falling behind the protrusions 302. The details will not be elaborated further here; when the sorting tray 3 rotates, the garbage on the sorting tray body 301 is pushed towards the protrusion 302 by the push rod 5, and falls into the garbage storage box 10 below along the direction guided by the protrusion 302 and the baffle 305, ensuring that the garbage can enter the corresponding garbage storage box 10, avoiding the garbage from falling to other places, ensuring the accuracy and efficiency of the garbage sorting and storage process, so that different types of garbage can be put in their proper places, laying a good foundation for subsequent garbage treatment, recycling and other work, and improving the garbage sorting effect, which will not be elaborated further here.

[0059] In this embodiment, a flexible fabric 11 with gaps at a specific height is provided at the contact point between the dry waste inlet 1011 and the sorting tray 3, and at the contact point between the wet waste inlet 1012 and the filter tray 801, as shown in the figure. The flexible fabric 11 with gaps at a certain height at the contact point between the dry waste inlet 1011 and the sorting tray 3 allows for cushioning during the disposal of dry waste. Some dry waste with sharp edges or large volumes may collide with the sorting tray 3 during its fall. To prevent dry waste from bouncing out of the dry waste inlet 1011 due to impact and overflowing outside the device, details are omitted here. A flexible, slit fabric 11 of a certain height is installed at the contact point between the wet waste inlet 1012 and the drain 801. This prevents liquid from splashing out due to impact from the force or volume of the wet waste during disposal, allowing moisture in the wet waste to flow along the slit fabric 11 into the filter disc 801, preventing soiling of surrounding components and reducing the burden of manual cleaning. Further details are omitted here.

[0060] In this embodiment, the smoke alarm 4 is installed on the top plate 11' of the outer cylinder and is located inside the device. Smoke has the characteristic of naturally rising. As shown in the figure, the smoke alarm 4 installed on the top plate 11' of the outer cylinder can detect the smoke generated and rising from inside the trash can in a timely and accurate manner. When smoke is generated inside the trash can due to certain reasons, such as spontaneous combustion of trash or the presence of flammable and volatile substances that can produce smoke, the smoke will gather above the outer cylinder 1 immediately. The smoke alarm 4 located on the top plate 11' of the outer cylinder can quickly capture the smoke signal and achieve rapid early warning. Further details are omitted here.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
