However, there is a lack of corresponding devices based on advanced algorithms. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a sorting trash can that improves sorting accuracy and adapts to complex-shaped trash.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sorting trash can, comprising a frame, characterized in that: an upper conveying device, a lower conveying device, a dispensing mechanism, and several collection boxes are installed on the frame; the lower conveying device is used to transfer the trash output by the upper conveying device, and the belts of the upper conveying device and the lower conveying device run in opposite directions; the dispensing mechanism is used to receive the trash output by the lower conveying device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6 As shown:

[0029] A sorting trash can includes a frame 1, which is a rectangular frame assembled from aluminum profiles and corner brackets. An upper conveyor 2, a lower conveyor 3, a dispensing mechanism 4, and several collection boxes 5 are installed on the frame 1. The lower conveyor 3 is used to transfer the trash output from the upper conveyor 2, and the belts of the upper conveyor 2 and the lower conveyor 3 run in opposite directions. The dispensing mechanism 4 is used to receive the trash output from the lower conveyor 3.

[0030] It also includes an identification component 61 for classifying and detecting the waste transported by the upper conveyor 2 and the lower conveyor 3. The disposal mechanism 4 disposes of the waste into the corresponding collection bin 5 according to the classification result of the identification component 61.

[0031] The side plates of the unloading points of the upper conveyor 2 and the lower conveyor 3 are provided with detection through holes 8 for installing infrared beam sensors 9;

[0032] The top of the frame 1 is fixedly connected to the top cover 6. Two sets of identification components 61 are installed on the lower surface of the top cover 6. The two sets of identification components 61 detect the garbage on the upper conveyor 2 and the lower conveyor 3 respectively. The identification component 61 includes an identification camera 611 and an infrared sensor 612. The identification camera 611 and the infrared sensor 612 are installed on the lower surface of the top cover 6 through a bracket.

[0033] In this embodiment, with the acceleration of urbanization and population growth, the amount of waste generated has increased dramatically, leading to environmental pollution and resource waste. Therefore, implementing waste sorting to optimize resource recycling and reduce environmental burden has become a key focus.

[0034] Traditional waste sorting relies mainly on manual labor, which is inaccurate and inefficient, creating a demand for more efficient and intelligent waste sorting solutions.

[0035] In recent years, the rapid development of technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), and Machine Vision has provided a solid technical foundation for the research and development of intelligent waste sorting systems. These technologies can achieve automatic identification, sorting, and processing of waste, improving the accuracy and efficiency of sorting.

[0036] Public awareness of environmental protection has gradually increased, promoting the popularization of intelligent waste sorting. People hope to use intelligent technology to improve their living environment, which has also increased their acceptance and participation in waste sorting.

[0037] Both the upper conveyor 2 and the lower conveyor 3 can be belt conveyors. Garbage needs to be deposited onto the upper conveyor 2 one by one. When garbage is deposited onto the upper conveyor 2, it is first detected by the infrared sensor 612 in the identification component 61. This indicates that garbage has fallen onto the upper conveyor 2, and then the visual recognition system is activated. The identification camera 611 takes a picture of the garbage on the upper conveyor 2 to identify its type. After the identification is complete, the upper conveyor 2 is activated, unloading the garbage onto the lower conveyor 3. During this process, the infrared beam sensor 9 at the unloading point of the upper conveyor 2 detects that garbage is being conveyed and is about to fall onto the lower conveyor 3. At this time, the lower conveyor 3 is activated. Figure 1As shown in the example, assuming the lower conveyor 3 can transport the garbage to the left, then the upper conveyor 2 can transport the garbage to the right. Before the garbage falls from the upper conveyor 2 onto the lower conveyor 3, the lower conveyor 3 has already started working. Since the upper conveyor 2 and the lower conveyor 3 operate in opposite directions, there is a certain probability that the garbage will flip when it falls onto the lower conveyor 3, and the shape or the part of the garbage that is facing upward will be changed. By visually recognizing the garbage again through the recognition camera 611 in another set of recognition components 61, the type of garbage can be judged from multiple angles, avoiding the situation of inaccurate judgment at one time. It should be noted that when the garbage falls onto the lower conveyor 3, it will also be detected by the infrared sensor 612 in another set of recognition components 61. At this time, the lower conveyor 3 will continue to rotate for a preset stroke and then stop, so as to better change the position or shape of the garbage. After stopping, it is beneficial for the recognition camera 611 to take pictures, avoiding unclear pictures from affecting the judgment.

[0038] The main unit 7 is mounted on the frame 1. The main unit 7 includes an STM32 main control module, a sensor module, and a motor drive module. The STM32 main control module, as the core controller of the entire system, is responsible for receiving data collected by the sensors, running image recognition and control algorithms, and outputting control signals to the motor drive module and sorting execution elements based on the algorithm results. The sensor module includes a camera, an infrared sensor 612, and an infrared beam sensor 9. The recognition camera 611 operates based on the principle of an image sensor (such as CMOS), collecting image data through line-by-line scanning to provide raw data for image recognition. It is installed above the conveyor device, capturing images of waste in real time and converting the light signals into electrical signals before transmitting them to the STM32 main control module. The infrared beam sensor 9... The infrared sensor 9 utilizes the characteristics of infrared emission and reception to detect whether garbage has reached a specific location or whether there are obstacles. When the infrared light is blocked, the sensor outputs a level change signal to notify the STM32 main control module to perform corresponding processing. The motor drive module drives the motor of the conveying device and the actuator of the dispensing mechanism 4 according to the control signal output by the STM32 main control module. The servo motor of the dispensing mechanism 4 can be set according to the type of garbage to ensure that all types of garbage can be accurately sorted into the corresponding collection bins 5. The electrical control system may also include a power module to provide a stable power supply for the entire system. The power module can be powered by batteries or external power supply and has power management functions to optimize power efficiency and reduce energy consumption.

[0039] In an optional embodiment, there are four collection boxes 5 arranged in a matrix in four directions, and the dispensing mechanism 4 is located above the center of the four collection boxes 5.

[0040] In this implementation, Figure 1There are only two display collection bins 5, and there is still space on the left side for placing two collection bins 5. There are four collection bins 5, which are distributed in a matrix in four directions. That is, the four collection bins 5 are arranged in the way of the "mouth" character in the character "qi". This is beneficial for the feeding mechanism 4 to throw garbage into the corresponding collection bin 5 through a simple rotation action. The collection bins 5 are set to four mainly because the common domestic waste classification standard usually adopts the four-category method, corresponding to the four collection bins 5, recyclables (such as paper, plastic, glass, etc.), hazardous waste (such as batteries, lamp tubes, expired medicines, etc.), kitchen waste (perishable waste such as food residues, fruit peels, etc.), and other waste (non-hazardous waste other than the above three categories, such as tissues, dust, etc.).

[0041] In an optional embodiment, the feeding mechanism 4 includes a feeding tray 41, a rotating bracket 42, an upper servo motor 43 and a lower servo motor 44. The lower servo motor 44 is installed on the frame 1, the power output end of the lower servo motor 44 is fixedly connected to the upper servo motor 43, the power output end of the upper servo motor 43 is fixedly connected to the bottom end of the rotating bracket 42, and the top end of the rotating bracket 42 is fixedly connected to the bottom end of the feeding tray 41.

[0042] In this embodiment, as Figure 4 and 6 shown, the lower servo motor 44 is installed on the frame 1 through a mounting bracket, the output shaft of the lower servo motor 44 is perpendicular to the ground, and the lower servo motor 44 can drive the upper servo motor 43 to rotate in the horizontal direction. Of course, there is a mounting bracket outside the upper servo motor 43, and the upper servo motor 43 is fixedly connected to the output shaft of the lower servo motor 44 through the mounting bracket. The output shaft of the upper servo motor 43 is horizontally arranged, and the output shaft of the upper servo motor 43 can drive the rotating bracket 42 to rotate, so that the rotating bracket 42 drives the feeding tray 41 to swing up and down.

[0043] In an optional embodiment, the feeding tray 41 is a quadrangular pyramid structure with a larger top and a smaller bottom. The four corners of the feeding tray 41 respectively point to the four collection bins 5, and the diagonal connection line of the feeding tray 41 is orthogonally arranged in space with the driving shaft of the upper servo motor 43.

[0044] In this embodiment, since there are four collection bins 5, in order to ensure that the garbage on the feeding tray 41 can be accurately thrown into the corresponding collection bin 5, on the basis that the four corners of the feeding tray 41 respectively point to the four collection bins 5, the placement position of the upper servo motor 43 is changed so that the output axis line of the upper servo motor 43 is parallel to the diagonal connection line of the feeding tray 41 in space. Since the angles between the four side faces and the bottom surface of the feeding tray 41 are the same, and the areas of the four side faces are also the same, therefore, if the output axis line of the servo motor is parallel to one diagonal connection line of the feeding tray 41 in space, then the other one is orthogonally arranged in space. When the feeding tray 41 feeds materials, the garbage slides down along the inner angle of the feeding tray 41 into the collection bin 5 with higher accuracy.

[0045] In an optional embodiment, mounting holes 51 for mounting infrared beam sensors 9 are provided on both opposite sides of the collection box 5.

[0046] In this embodiment, the infrared beam sensor 9 installed on the collection box 5 can detect whether the garbage in the collection box 5 is full and remind the staff to clean it. When the garbage in the collection box 5 is full, the infrared light is blocked for a long time.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
