Description

Technical Field

[0001] This application relates to the field of garbage truck technology, specifically to a garbage sorting cart. Background Technology

[0002] With the acceleration of global urbanization, the annual output of urban waste continues to rise, becoming one of the main sources of environmental pollution and resource waste. Traditional road waste disposal relies on manual sweeping and dumping into garbage trucks, followed by manual sorting at collection points or treatment plants. This model is not only inefficient and labor-intensive, but its sorting accuracy is also significantly affected by human factors, often resulting in classification errors due to fatigue or lack of experience. This leads to the mishandling of large amounts of recyclable resources (such as landfilling or incineration), further exacerbating the environmental burden and resource depletion. Existing semi-automatic sorting equipment is limited to waste collection and cannot achieve parallel sorting of multiple categories. Utility Model Content

[0003] In view of the above problems, this application provides a garbage sorting cart to solve the problem that existing garbage carts cannot perform sorting.

[0004] To achieve the above objectives, the inventors provide a waste sorting cart, which includes:

[0005] A mobile cart includes a cart body, the cart body having a cavity; the upper part of the cart body has a window corresponding to the cavity, so that garbage can fall into the cavity through the window and be located on a first conveyor belt at one end of a first conveyor assembly; the cart body has detachable doors corresponding to a plurality of sorting bins;

[0006] Several sorting boxes are located at the bottom of the cavity and arranged along the first direction;

[0007] A first transmission component is disposed within the cavity and located above the sorting box; it includes a first transmission belt, a first transmission belt drive, balls, and a ball drive; the first transmission belt transmits from one end of the first transmission component to the other end along a first direction and is driven by the first transmission belt drive; the balls are disposed on the first transmission belt and roll along a second direction and are driven by the ball drive; the first direction and the second direction intersect.

[0008] The identification unit is located inside the cavity and above one end of the first transmission component. It identifies the garbage on the conveyor belt to obtain the garbage type and the coordinates of the garbage in the current pixel coordinate system.

[0009] The main control unit controls the movement of the mobile trolley and is electrically connected to the first conveyor belt drive and the ball drive of the first transmission assembly to drive the first conveyor belt to transmit in a first direction and the balls to roll in a second direction; it is also electrically connected to the identification unit to drive the identification unit to identify the waste located on the conveyor belt.

[0010] The power supply unit provides power to the power consumption unit;

[0011] Waste falls into the cavity through the window and is located on the conveyor belt at one end of the first transmission component. The main control unit drives the recognition unit to identify the waste on the conveyor belt and obtain the waste category and the coordinates of the waste in the current pixel coordinate system. Based on the waste category and the coordinates of the waste in the current pixel coordinate system, the main control unit controls the first conveyor belt driver to drive the first conveyor belt of the first transmission component to transport the waste from one end of the first transmission component to the other end, and controls the ball drive to drive the ball to roll so that the waste falls into the corresponding sorting bin.

[0012] Furthermore, the first conveyor belt is provided with a corresponding friction belt for each sorting bin; the friction belt is driven along the second direction, and the length of the friction belt is set to correspond to the width of the first conveyor belt; the friction belt abuts against the ball bearings, so that the friction belt drives the ball bearings to roll along the second direction, so that the garbage falls into the corresponding sorting bin.

[0013] Furthermore, the bottom of the cavity has four sorting bins. The first transmission component is positioned above the first three sorting bins along the first direction, and the length of the first transmission component extending in the first direction is the same as the total length of the first three sorting bins. This allows the waste of the corresponding waste type in the first three sorting bins to be transported from one end of the first transmission component to the other end via the first transmission belt, where the waste is dropped into the corresponding sorting bin by the rolling of the ball bearings. The waste of the corresponding waste type in the last sorting bin is transported to the other end of the first transmission component via the first transmission belt, where the waste is dropped into the last sorting bin.

[0014] Furthermore, the cavity is also provided with a second transmission component, which is located below the window and above the first transmission component in the height direction; the second transmission component includes a second transmission belt and a second transmission belt driver, the second transmission belt transmits to the first transmission belt along the second direction and is driven by the second transmission belt driver; the first transmission belt and the second transmission belt are adjacent or partially overlapped in the height direction; the second transmission belt driver is electrically connected to the main control unit so that the main control unit controls the second transmission belt driver to drive the second transmission belt.

[0015] Furthermore, it also includes a cover plate, which is configured to open and close the window.

[0016] Furthermore, it also includes an opening / closing sensor disposed on the surface of the vehicle body and a cover plate driving assembly for opening and closing the cover plate. The opening / closing sensor and the cover plate driving component of the cover plate driving assembly are electrically connected to the main control unit so that the main control unit receives the signal from the opening / closing sensor and controls the cover plate driving component to drive the cover plate to open and close the window.

[0017] Furthermore, the cover plate is slidably connected to the window;

[0018] The cover plate drive assembly also includes a first link and a second link. The fixed end of the motor is located on the surface of the vehicle body or cavity away from the window. The output end of the motor is rotatably connected to one end of the first link. One end of the second link is rotatably connected to the other end of the first link, and the other end is rotatably connected to the cover plate.

[0019] Furthermore, it also includes a wireless communication unit, which is electrically connected to the main control unit.

[0020] Furthermore, it also includes a voice interaction unit, which is electrically connected to the main control unit.

[0021] Furthermore, it also includes a positioning unit, which is electrically connected to the main control unit.

[0022] Unlike existing technologies, the above technical solution sets up several sorting bins inside the mobile vehicle. The identification unit scans the waste category in real time and dynamically allocates the waste to the corresponding sorting bin with the help of the transmission component, thereby achieving simultaneous sorting of multiple types of waste and reducing the time-consuming long process of "manual collection → centralized transportation → fixed sorting" in the traditional mode.

[0055] See Figure 1-6 As shown, a garbage sorting vehicle has several sorting bins 40 set inside the vehicle body of the mobile vehicle 10. The identification unit 60 scans the garbage category in real time and dynamically allocates the garbage to the corresponding sorting bin 40 in conjunction with the transmission component, so as to realize the simultaneous sorting of multiple types of garbage and reduce the long process time of "manual collection → centralized transportation → fixed sorting" in the traditional mode.

[0056] See below for reference. Figures 1-5 An implementation of a waste sorting cart is provided, comprising:

[0057] The mobile trolley 10 includes a vehicle body, the vehicle body having a cavity 101; the upper part of the vehicle body has a window 102 corresponding to the cavity 101, so that garbage can fall into the cavity 101 through the window 102 and is located on the first conveyor belt 201 at one end of the first conveyor assembly 20; the vehicle body is provided with detachable doors 103 corresponding to a plurality of sorting bins 40.

[0058] Several sorting boxes 40 are located at the bottom of the cavity 101 and arranged along the first direction;

[0059] A first transmission assembly 20 is disposed within the cavity 101 and located above the sorting box 40; it includes a first transmission belt 201, a first transmission belt drive 202, balls 203, and a ball drive 205; the first transmission belt 201 transmits data from one end of the first transmission assembly 20 to the other end along a first direction and is driven by the first transmission belt drive 202; the balls 203 are disposed on the first transmission belt 201 and roll along a second direction, driven by the ball drive 205; the first direction and the second direction intersect.

[0060] The identification unit 60 is located inside the cavity 101 and above one end of the first transmission component 20. It identifies the garbage located on the conveyor belt to obtain the garbage type and the coordinates of the garbage in the current pixel coordinate system.

[0061] The main control unit 90 controls the movement of the mobile trolley 10 and is electrically connected to the first conveyor belt drive 202 and the ball drive 205 of the first transmission assembly 20 to drive the first conveyor belt 201 to transmit in a first direction and the ball 203 to roll in a second direction; it is also electrically connected to the identification unit 60 to drive the identification unit 60 to identify the waste located on the conveyor belt.

[0062] Power supply unit 50 supplies power to the power consumption unit;

[0063] Waste falls into cavity 101 through window 102 and is located on the conveyor belt at one end of the first transmission component 20. The main control unit 90 drives the recognition unit 60 to identify the waste on the conveyor belt and obtain the waste type and the coordinates of the waste in the current pixel coordinate system. Based on the waste type and the coordinates of the waste in the current pixel coordinate system, the main control unit 90 controls the first conveyor belt drive 202 to drive the first conveyor belt 201 of the first transmission component 20 to transport the waste from one end of the first transmission component 20 to the other end, and controls the ball drive 205 to drive the ball 203 to roll so that the waste falls into the corresponding sorting box 40.

[0064] See Figure 4 As shown, the upper part of the vehicle body has a window 102 corresponding to the cavity 101, so that garbage can fall into the cavity 101 through the window 102. The window 102 can be located in the area above the garbage sorting trolley, and it can be located on the upper surface or side of one end of the vehicle body, so that the garbage can be transported by the first conveyor belt 201 and can be identified by the identification unit 60. The size of the window 102 can be adapted to common garbage (such as 20-40cm in width) so that garbage can fall into the cavity 101 through the window 102.

[0065] See Figure 1 and Figure 2As shown, the aforementioned door 103 is detachably connected to the vehicle body and can be connected in a flexible manner such as by snap-fit, sliding, or hinge. This allows the sorting bin 40 inside the vehicle body to be quickly moved out of the cavity 101 by flexibly removing the door 103, and the garbage in the sorting bin 40 to be dumped into the corresponding garbage sorting and recycling area.

[0066] See Figure 2 and Figure 3 As shown, the ball bearings 203 are mounted on the first conveyor belt 201 and roll along the second direction, driven by the ball bearing drive component 205. An array of mounting holes can be formed on the surface of the first conveyor belt 201, and the ball bearings 203 are placed inside the mounting holes. The tops of the ball bearings 203 protrude above the surface of the conveyor belt to ensure contact with the bottom of the waste. Specifically, a corresponding friction belt 204 can be provided between the first conveyor belts and corresponding to the sorting bins 40. The friction belt 204 moves along the second direction, and its length corresponds to the width of the first conveyor belt 201. The friction belt 204 abuts against the ball bearings 203, so that the friction belt 204 drives the ball bearings 203 to roll along the second direction, causing the waste to fall into the corresponding sorting bin 40.

[0067] Preferably, the first direction and the second direction are perpendicular. The vertical layout allows the longitudinal conveying of the conveyor belt and the lateral sorting of the ball bearings 203 to be orthogonally superimposed, eliminating the need for multiple conveyor belts or complex turning mechanisms. This makes the structure of the first conveying component 20 more compact, while improving sorting accuracy and reducing the risk of mutual interference during the simultaneous sorting of multiple types of waste.

[0068] See Figure 4 As shown, the aforementioned identification unit 60 includes a camera, such as an RGB-D camera or a binocular camera, for waste identification, classification, and depth estimation. The camera captures images of the waste on the conveyor belt, and the images are input into a target detection algorithm (such as a trained YOLOv5 target detection model) for identification to obtain the waste category, location, etc. Based on the waste category and location, the main control unit 90 controls the first conveyor belt drive 202 to drive the first conveyor belt 201 of the first conveyor assembly 20 to transport the waste from one end of the first conveyor assembly 20 to the other end, and controls the ball drive 205 to drive the balls 203 to roll so that the waste falls into the corresponding classification bin 40.

[0069] The aforementioned power supply unit 50 provides power to the waste sorting cart and may include solid-state batteries, hydrogen fuel cells, and solar cells (see [link]). Figure 1 One or more combinations of the above (as shown), and of course, an external charging interface can be set to charge the power supply unit 50.

[0070] See Figure 2As shown, the aforementioned sorting bins 40 may include, but are not limited to, recyclables, kitchen waste, hazardous waste, and other waste. The following uses four sorting bins 40—recyclables, kitchen waste, hazardous waste, and other waste—as examples to further illustrate this application.

[0071] The extension of the first transmission component 20 in the first direction may be the same as or different from the sum of the lengths of the four sorting bins 40 in the first direction.

[0072] In some embodiments, the first conveying component 20 is positioned above the four sorting bins 40 along the first direction, and the length of the first conveying component 20 in the first direction is the same as the total length of the four sorting bins 40. This allows waste of the corresponding waste type from the four sorting bins 40 to be transported by the first conveyor belt 201 from one end of the first conveying component 200 to the other, where the waste is rolled by the ball bearings 203 and falls into the corresponding sorting bin 40. In some embodiments, the first conveying component 20 may be positioned above the first three sorting bins 40 along the first direction, and the length of the first conveying component 20 in the first direction is the same as the total length of the first three sorting bins 40. This allows waste of the corresponding waste type from the first three sorting bins 40 to be transported by the first conveyor belt 201 from one end of the first conveying component 201, where the waste is rolled by the ball bearings 203 and falls into the corresponding sorting bin 40. Waste of the corresponding waste type from the last sorting bin 40 is transported by the first conveyor belt 201 to the other end of the first conveying component 200, where the waste falls into the last sorting bin 40.

[0073] See Figure 2As shown, in some embodiments, a second transmission component 30 is further provided inside the cavity 101. The second transmission component 30 is located below the window 102 and above the first transmission component 20 in the height direction. The second transmission component 30 includes a second transmission belt 301 and a second transmission belt driver 302. The second transmission belt 301 transmits to the first transmission belt 201 along the second direction and is driven by the second transmission belt driver 302. The first transmission belt 201 and the second transmission belt 301 are adjacent or partially overlapped in the height direction. The second transmission belt driver is electrically connected to the main control unit 90 so that the main control unit 90 controls the second transmission belt driver to drive the second transmission belt 301. When the main control unit 90 receives a signal that garbage has fallen onto the second conveyor belt 301 (e.g., the weight sensor detects a pressure change, or the photoelectric sensor detects an object blocking it), it will immediately activate the second conveyor belt drive to make the second conveyor belt 301 run at a set speed, conveying the garbage along the second direction onto the first conveyor belt 201. At this time, the main control unit 90 controls the first conveyor belt drive 202 to drive the first conveyor belt 201 of the first conveyor assembly 20 to transport the garbage from one end of the first conveyor assembly 20 to the other end, and controls the ball drive 205 to drive the ball 203 to roll so that the garbage falls into the corresponding sorting bin 40. In this embodiment, the identification unit 60 can be located above the second transmission component 30 to identify the garbage on the second transmission belt 301 to obtain the garbage category; the main control unit 90 starts the second transmission belt drive to make the second transmission belt 301 run at a set speed, and transport the garbage along the second direction to the first transmission belt 201; the main control unit 90 then controls the first transmission belt drive 202 to drive the first transmission belt 201 of the first transmission component 20 to transport the garbage from one end of the first transmission component 20 to the other end according to the garbage category, and controls the ball drive 205 to drive the ball 203 to roll so that the garbage falls into the corresponding classification bin 40.

[0074] See Figure 4 As shown, in some embodiments, a cover plate 104 is also included, which is disposed corresponding to the window 102 to open and close the window 102. The opening and closing method can be sliding connection, snap-fit ​​connection, hinge, etc. The cover plate 104 is used to prevent pollution diffusion, such as controlling odors and preventing the breeding of mosquitoes and flies.

[0075] See Figure 4As shown, in some embodiments, in addition to the cover plate 104, an opening / closing sensor 802 and a cover plate driving assembly 70 for opening and closing the cover plate are also included. The opening / closing sensor 802 and the cover plate driving component of the cover plate driving assembly 70 are electrically connected to the main control unit 90 so that the main control unit 90 receives the signal from the opening / closing sensor 802 and controls the cover plate driving component to drive the cover plate 104 to open and close the window 102. The opening / closing sensor 802 can be an infrared sensor to detect human bodies and can monitor external commands or environmental changes in real time. Specifically, the cover plate driving assembly 70 includes a motor 701. When the opening / closing sensor 802 receives a trigger signal to open or close the window 102 (such as a human body approaching, button operation, or remote control command), it transmits the signal to the main control unit 90. The main control unit 90 converts the rotation or linear motion of the motor 701 into the opening and closing action of the cover plate according to a preset program, thereby realizing the opening or closing of the window 102 by the cover plate 104 to meet the needs of garbage disposal.

[0076] See Figure 4 As shown below, the opening and closing window 102 of the cover plate 104 is further explained using a sliding connection. The cover plate 104 is slidably connected to the window 102; the cover plate driving assembly 70 also includes a first connecting rod 702 and a second connecting rod 703. The fixed end of the motor 701 is located on the vehicle body or the inner surface of the cavity 101 away from the window 102. The output end of the motor 701 is rotatably connected to one end of the first connecting rod 702, and one end of the second connecting rod 703 is rotatably connected to the other end of the first connecting rod 702, and the other end is rotatably connected to the cover plate 104.

[0077] See Figure 6 As shown, in some embodiments, the waste sorting cart further includes a wireless communication unit 801, which is electrically connected to the main control unit 90. The wireless communication unit 801 includes Bluetooth, Wi-Fi, 4G / 5G, infrared, etc., so that a mobile device can be electrically connected to the main control unit 90 via the wireless communication unit 801 to precisely control the movement of the mobile cart 10, enabling it to reach a designated location. The mobile device may include, but is not limited to, a PS2 controller, a mobile phone, a computer, etc.

[0078] See Figure 6As shown, in some embodiments, the waste sorting cart also includes a voice interaction unit 805, which is electrically connected to the main control unit 90. The voice interaction unit 805 is based on a microphone, an audio module, and a digital amplifier. The microphone acts as the "ear" for sound acquisition, supporting omnidirectional sound pickup and accurately capturing voice commands from the vicinity of the waste sorting cart, ensuring clear and distortion-free sound signals. The audio module is responsible for the digital processing of sound signals, filtering environmental noise through noise reduction algorithms and converting the original speech into a digital signal that can be recognized by the system. The digital amplifier serves as the voice broadcaster, using the voice interaction unit 805 to control the waste sorting cart with voice commands. The voice interaction unit 805 can also connect to the internet via a wireless communication module (such as 4G / 5G, Wi-Fi), incorporating large AI models such as Deepseek and Doubao to achieve intelligent language communication. Leveraging the powerful natural language processing capabilities of the large-scale model, the waste sorting cart can quickly understand complex user commands, such as "transport kitchen waste to the B-zone processing station," and instantly parse them into executable control signals, transmitting them to the main control unit 90 to drive the cart to complete the corresponding actions. Simultaneously, the large-scale model also endows the waste sorting cart with intelligent response capabilities. When users ask, "Which types of waste are recyclable?", it can combine local knowledge base and cloud data to provide professional answers in easy-to-understand language. Furthermore, the system supports multi-turn dialogue and contextual understanding; users can continuously ask follow-up questions such as "How are glass bottles classified?", and the cart can accurately respond based on the preceding context, significantly improving the ease of operation and intelligence of the waste sorting cart.

[0079] See Figure 6 As shown, in some embodiments, the garbage sorting cart also includes a display unit 804 to present information intuitively and facilitate operation. The display unit 804 typically integrates modules such as a high-definition touch screen, status indicator lights, and data dashboard.

[0080] See Figure 6 As shown, in some embodiments, the waste sorting cart further includes a positioning unit 803, which is electrically connected to the main control unit 90. The positioning unit 803 can display the current location in real time, and the positioning unit 803 includes, but is not limited to, BDS (BeiDou Navigation Satellite System), GPS (Global Positioning System), etc.

[0081] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.

The waste of the waste category corresponding to the last sorting bin is transported to the other end of the first transmission component by the first transmission belt, so that the waste falls into the last sorting bin. A first transmission assembly is disposed within the cavity and located above the sorting bins; it includes a first transmission belt, a first transmission belt drive, ball bearings, and a ball bearing drive; the first transmission belt transmits waste from one end of the first transmission assembly to the other along a first direction and is driven by the first transmission belt drive; the ball bearings are disposed on the first transmission belt and roll along a second direction, driven by the ball bearing drive; the first and second directions intersect; a corresponding friction belt is provided between the first transmission belts and for each sorting bin; the friction belts travel along the second direction, and the length of the friction belts corresponds to the width of the first transmission belts; the friction belts abut against the ball bearings, so that the friction belts drive friction to guide the ball bearings to roll along the second direction, causing the waste to fall into the corresponding sorting bins; A second transmission component is located below the window and above the first transmission component in the height direction. The second transmission component includes a second transmission belt and a second transmission belt driver. The second transmission belt transmits to the first transmission belt along the second direction and is driven by the second transmission belt driver. The first and second transmission belts are adjacent or partially overlap in the height direction. The second transmission belt driver is electrically connected to the main control unit so that the main control unit controls the second transmission belt driver to drive the second transmission belt. The identification unit is located inside the cavity and above one end of the first transmission component. It identifies the garbage on the conveyor belt to obtain the garbage type and the coordinates of the garbage in the current pixel coordinate system. The main control unit controls the movement of the mobile trolley and is electrically connected to the first conveyor belt drive and the ball drive of the first transmission assembly to drive the first conveyor belt to transmit in a first direction and the balls to roll in a second direction; it is also electrically connected to the identification unit to drive the identification unit to identify the waste located on the conveyor belt. The power supply unit provides power to the power consumption unit; Waste falls into the cavity through the window and is located on the conveyor belt at one end of the first transmission component. The main control unit drives the recognition unit to identify the waste on the conveyor belt and obtain the waste category and the coordinates of the waste in the current pixel coordinate system. Based on the waste category and the coordinates of the waste in the current pixel coordinate system, the main control unit controls the first conveyor belt driver to drive the first conveyor belt of the first transmission component to transport the waste from one end of the first transmission component to the other end, and controls the ball drive to drive the ball to roll so that the waste falls into the corresponding sorting bin.
